18TF/03 Make the exiwhat support code safe for signals. Previously Exim might
19 lock up or crash if it happened to be inside a call to libc when it
20 got a SIGUSR1 from exiwhat.
21
22 The SIGUSR1 handler appends the current process status to the process
23 log which is later printed by exiwhat. It used to use the general
24 purpose logging code to do this, but several functions it calls are
25 not safe for signals.
26
27 The new output code in the SIGUSR1 handler is specific to the process
28 log, and simple enough that it's easy to inspect for signal safety.
29 Removing some special cases also simplifies the general logging code.
30 Removing the spurious timestamps from the process log simplifies
31 exiwhat.

33TF/04 Improved ratelimit ACL condition.
34
35 The /noupdate option has been deprecated in favour of /readonly which
36 has clearer semantics. The /leaky, /strict, and /readonly update modes
37 are mutually exclusive. The update mode is no longer included in the
38 database key; it just determines when the database is updated. (This
39 means that when you upgrde Exim will forget old rate measurements.)
40
41 Exim now checks that the per_* options are used with an update mode that
42 makes sense for the current ACL. For example, when Exim is processing a
43 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
44 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
45 must specify per_mail/readonly. If you omit the update mode it defaults to
46 /leaky where that makes sense (as before) or /readonly where required.
47
48 The /noupdate option is now undocumented but still supported for
49 backwards compatibility. It is equivalent to /readonly except that in
50 ACLs where /readonly is required you may specify /leaky/noupdate or
51 /strict/noupdate which are treated the same as /readonly.
52
53 A useful new feature is the /count= option. This is a generalization
54 of the per_byte option, so that you can measure the throughput of other
55 aggregate values. For example, the per_byte option is now equivalent
56 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
57
58 The per_rcpt option has been generalized using the /count= mechanism
59 (though it's more complicated than the per_byte equivalence). When it is
60 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
61 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
62 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
63 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
64 Note that using per_rcpt with a non-readonly update mode in more than
65 one ACL will cause the recipients to be double-counted. (The per_mail
66 and per_byte options don't have this problem.)
67
68 The handling of very low rates has changed slightly. If the computed rate
69 is less than the event's count (usually one) then this event is the first
70 after a long gap. In this case the rate is set to the same as this event's
71 count, so that the first message of a spam run is counted properly.
72
73 The major new feature is a mechanism for counting the rate of unique
74 events. The new per_addr option counts the number of different
75 recipients that someone has sent messages to in the last time period. It
76 behaves like per_rcpt if all the recipient addresses are different, but
77 duplicate recipient addresses do not increase the measured rate. Like
78 the /count= option this is a general mechanism, so the per_addr option
79 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
80 example, measure the rate that a client uses different sender addresses
81 with the options per_mail/unique=$sender_address. There are further
82 details in the main documentation.

633 were called 'true' and it seems that C99 defines that as a reserved

654PH/01 Another patch from the Sieve maintainer.
655
6a3bceb1
PH
656PH/02 When an IPv6 address is converted to a string for single-key lookup
657 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
658 dots are used instead of colons so that keys in lsearch files need not
659 contain colons. This was done some time before quoting was made available
660 in lsearch files. However, iplsearch files do require colons in IPv6 keys
661 (notated using the quote facility) so as to distinguish them from IPv4
662 keys. This meant that lookups for IP addresses in host lists did not work
663 for iplsearch lookups.
664
665 This has been fixed by arranging for IPv6 addresses to be expressed with
666 colons if the lookup type is iplsearch. This is not incompatible, because
667 previously such lookups could never work.
668
669 The situation is now rather anomolous, since one *can* have colons in
670 ordinary lsearch keys. However, making the change in all cases is
671 incompatible and would probably break a number of configurations.

676MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
677 conversion specification without a maximum field width, thereby enabling
678 a rogue spamd server to cause a buffer overflow. While nobody in their
679 right mind would setup Exim to query an untrusted spamd server, an
680 attacker that gains access to a server running spamd could potentially
681 exploit this vulnerability to run arbitrary code as the Exim user.

MH
686MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
687 a directory entry by the name of the lookup key. Previously, if a
688 symlink pointed to a non-existing file or a file in a directory that
689 Exim lacked permissions to read, a lookup for a key matching that
690 symlink would fail. Now it is enough that a matching directory entry
691 exists, symlink or not. (Bugzilla 503.)

PH
874PH/29 SMTP synchronization checks are implemented when a command is read -
875 there is a check that no more input is waiting when there shouldn't be
876 any. However, for some commands, a delay in an ACL can mean that it is
877 some time before the response is written. In this time, more input might
878 arrive, invalidly. So now there are extra checks after an ACL has run for
879 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
880 pipelining has not been advertised.

895 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
896 was a macro that became an assignment, so it seemed to work. This has

926PH/40 When Exim receives a message, it writes the login name, uid, and gid of

928 behaving confusingly. When first started, it used values for whoever
929 started the daemon, but after a SIGHUP it used the Exim user (because it
930 calls itself on a restart). I have changed the code so that it now always
931 uses the Exim user.

936 with PIPELINING or a stupid MUA), the error message that was given to the
937 RCPT commands is included in the rejection of the DATA command. This is

58eb016e 953PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
954 the response to the final '.' that terminates a message, but only in the
955 case where the client has not sent further data following the '.'
956 (unfortunately, this is allowed). However, in many cases there won't be
957 any further data because there won't be any more messages to send. A call
958 to select() can be used: if it shows that the input is "ready", there is
959 either input waiting, or the socket has been closed. An attempt to read
960 the next input character can distinguish the two cases. Previously, Exim
58eb016e 961 would have sent an OK response which the client would never have see.

970-----------------
971
972PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
973 fixed by 4.65/MH/01 (is this a record?) are fixed:
974
975 (i) An empty string was always treated as zero by the numeric comparison
976 operators. This behaviour has been restored.
977
978 (ii) It is documented that the numeric comparison operators always treat
979 their arguments as decimal numbers. This was broken in that numbers
980 starting with 0 were being interpreted as octal.
981
982 While fixing these problems I realized that there was another issue that
983 hadn't been noticed. Values of message_size_limit (both the global option
984 and the transport option) were treated as octal if they started with 0.
985 The documentation was vague. These values are now always treated as
986 decimal, and I will make that clear in the documentation.

PH
1000PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1001 child addresses, Exim now panics and dies. Previously, because the count
1002 is held in a short int, deliveries were likely to be lost. As such a
1003 large number of recipients for a single message is ridiculous
1004 (performance will be very, very poor), I have chosen to impose a limit
1005 rather than extend the field.

1011TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1012 leftover -K file (the existence of which was triggered by #402).
1013 While we were at it, introduced process PID as part of the -K

1020
1021TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1022 in the DK code in transports.c. sendfile() is not really portable,

1028 in the field name.

2b1c6e3a
PH
1030PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1031 callout verification, Exim cached a "reject" for the entire domain. This
1032 is correct for most verifications, but it is not correct for a recipient
1033 verification with use_sender or use_postmaster set, because in that case
1034 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1035 case of MAIL FROM:<> rejection from other early rejections (e.g.
1036 rejection of HELO). When verifying a recipient using a non-null MAIL
1037 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1038 Whatever the result of the callout, the value of the domain cache is
1039 left unchanged (for any other kind of callout, getting as far as trying
1040 RCPT means that the domain itself is ok).

1074PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1075 hostname. This is wrong, because it relates to the incoming message (and
1076 probably the interface on which it is arriving) and not to the outgoing
1077 callout (which could be using a different interface). This has been
1078 changed to use the value of the helo_data option from the smtp transport
1079 instead - this is what is used when a message is actually being sent. If
1080 there is no remote transport (possible with a router that sets up host
1081 addresses), $smtp_active_hostname is used.

14aa5a05 1083PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1084 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1085 (a) The code assumed that strncpy() returns a negative number on buffer
1086 overflow, which isn't the case. Replaced with Exim's string_format()
1087 function.
1088 (b) There were several signed/unsigned issues. I just did the minimum
1089 hacking in of casts. There is scope for a larger refactoring.
1090 (c) The code used strcasecmp() which is not a standard C function.
1091 Replaced with Exim's strcmpic() function.
1092 (d) The code set only $1; it now sets $auth1 as well.
1093 (e) A simple test gave the error "authentication client didn't specify
1094 service in request". It would seem that Dovecot has changed its
1095 interface. Fortunately there's a specification; I followed it and
1096 changed what the client sends and it appears to be working now.

1101PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1102 address A is aliased to B and C, where B exists and C does not. Without
1103 -v the output is "A verified" because verification stops after a
1104 successful redirection if more than one address is generated. However,
1105 with -v the child addresses are also verified. Exim was outputting "A
1106 failed to verify" and then showing the successful verification for C,
1107 with its parentage. It now outputs "B failed to verify", showing B's
1108 parentage before showing the successful verification of C.

1110PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
1111 look up a TXT record in a specific list after matching in a combined
1112 list.
1113
322050c2
PH
1114PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1115 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1116 they consult the DNS. I had assumed they would set it the way they
1117 wanted; and indeed my experiments on Linux seem to show that in some
1118 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1119 To be on the safe side, however, I have now made the interface to
1120 host_find_byname() similar to host_find_bydns(), with an argument
1121 containing the DNS resolver options. The host_find_byname() function now
1122 sets these options at its start, just as host_find_bydns() does. The smtp
1123 transport options dns_qualify_single and dns_search_parents are passed to
1124 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1125 of host_find_byname() use the default settings of RES_DEFNAMES
1126 (qualify_single) but not RES_DNSRCH (search_parents).

PH
1128PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1129 spool_read_header() do less string testing, by means of a preliminary
1130 switch on the second character of optional "-foo" lines. (This is
1131 overdue, caused by the large number of possibilities that now exist.
1132 Originally there were few.) While I was there, I also converted the
1133 str(n)cmp tests so they don't re-test the leading "-" and the first
1134 character, in the hope this might squeeze out yet more improvement.

PH
1136PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1137 flag allowing group syntax was set by the header_syntax check but not
1138 turned off, possible causing trouble later; (2) The flag was not being
1139 set at all for the header_verify test, causing "group"-style headers to
1140 be rejected. I have now set it in this case, and also caused header_
1141 verify to ignore an empty address taken from a group. While doing this, I
1142 came across some other cases where the code for allowing group syntax
1143 while scanning a header line wasn't quite right (mostly, not resetting
1144 the flag correctly in the right place). These bugs could have caused
1145 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1147PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1148 with the "reply" argument non-NULL. The code, however (which originally
1149 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1150 but it didn't always do it. This confused somebody who was copying the
1151 code for some other use. I have removed all the tests.

PH
1153PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1154 feature that was used to support insecure browsers during the U.S. crypto
1155 embargo. It requires special client support, and Exim is probably the
1156 only MTA that supported it -- and would never use it because real RSA is
1157 always available. This code has been removed, because it had the bad
1158 effect of slowing Exim down by computing (never used) parameters for the
1159 RSA_EXPORT functionality.

PH
1161PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1162 authenticator to fail if there's a tab character in the incoming data

1164 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1165 if the connection is using TLS or if the remote IP is the same as the
1166 local IP, and the "valid-client-cert option" if a client certificate has
1167 been verified.

1199PH/30 Exim was sometimes attempting to deliver messages that had suffered
1200 address errors (4xx response to RCPT) over the same connection as other
1201 messages routed to the same hosts. Such deliveries are always "forced",
1202 so retry times are not inspected. This resulted in far too many retries
1203 for the affected addresses. The effect occurred only when there were more
1204 hosts than the hosts_max_try setting in the smtp transport when it had
1205 the 4xx errors. Those hosts that it had tried were not added to the list
1206 of hosts for which the message was waiting, so if all were tried, there
1207 was no problem. Two fixes have been applied:
1208
1209 (i) If there are any address or message errors in an SMTP delivery, none
1210 of the hosts (tried or untried) are now added to the list of hosts
1211 for which the message is waiting, so the message should not be a
1212 candidate for sending over the same connection that was used for a
1213 successful delivery of some other message. This seems entirely
1214 reasonable: after all the message is NOT "waiting for some host".
1215 This is so "obvious" that I'm not sure why it wasn't done
1216 previously. Hope I haven't missed anything, but it can't do any
1217 harm, as the worst effect is to miss an optimization.
1218
1219 (ii) If, despite (i), such a delivery is accidentally attempted, the
1220 routing retry time is respected, so at least it doesn't keep
1221 hammering the server.

1236PH/35 The error "getsockname() failed: connection reset by peer" was being
1237 written to the panic log as well as the main log, but it isn't really
1238 panic-worthy as it just means the connection died rather early on. I have
1239 removed the panic log writing for the ECONNRESET error when getsockname()
1240 fails.
1241
48c7f9e2
PH
1242PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1243 runs only) independently of the message's sender address. This meant
1244 that, if the 4xx error was in fact related to the sender, a different
1245 message to the same recipient with a different sender could confuse
1246 things. In particualar, this can happen when sending to a greylisting
1247 server, but other circumstances could also provoke similar problems.
1248 I have changed the default so that the retry time for these errors is now
1249 based a combination of the sender and recipient addresses. This change
1250 can be overridden by setting address_retry_include_sender=false in the
1251 smtp transport.

1522 tcp-wrappers gives "deny", whereas what one would like would be some
1523 kind of temporary error. A kludge has been added to help with this.
1524 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1525 554 error is used if errno is still zero or contains ENOENT (which occurs
1526 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

1611 generate an autoreply, and therefore failed to obtain an address for the
1612 autoreply, Exim could try to deliver to a non-existent relative file
1613 name, causing unrelated and misleading errors. What now happens is that
1614 it logs this as a hard delivery error, but does not attempt to create a

1633 changes:
1634
1635 (a) Failures to set uid/gid, the current directory, or a process leader
1636 in a subprocess such as that created by queryprogram now generate
1637 suitable debugging ouput when -d is set.

1646PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1647 additional section of a DNS packet that returns MX or SRV records.
1648 Instead, it always explicitly searches for A/AAAA records. This avoids
1649 major problems that occur when a DNS server includes only records of one
1650 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1651 fixed another bug: if SRV records were looked up and the corresponding
1652 address records were *not* found in the additional section, the port
1653 values from the SRV records were lost.

PH
1663PH/19 When calculating a retry time, Exim used to measure the "time since
1664 failure" by looking at the "first failed" field in the retry record. Now
1665 it does not use this if it is later than than the arrival time of the
1666 message. Instead it uses the arrival time. This makes for better
1667 behaviour in cases where some deliveries succeed, thus re-setting the
1668 "first failed" field. An example is a quota failure for a huge message
1669 when small messages continue to be delivered. Without this change, the
1670 "time since failure" will always be short, possible causing more frequent
1671 delivery attempts for the huge message than are intended.

PH
1768PH/42 The content-scanning code uses fopen() to create files in which to put
1769 message data. Previously it was not paying any attention to the mode of
1770 the files. Exim runs with umask(0) because the rest of the code creates
1771 files with open(), and sets the required mode explicitly. Thus, these
1772 files were ending up world-writeable. This was not a big issue, because,
1773 being within the spool directory, they were not world-accessible. I have
1774 created a function called modefopen, which takes an additional mode
1775 argument. It sets umask(777), creates the file, chmods it to the required
1776 mode, then resets the umask. All the relevant calls to fopen() in the
1777 content scanning code have been changed to use this function.

1814
1815 (i) Exim was not creating retry information for temporary errors given
1816 for individual recipients after the DATA command when the smtp transport
1817 was used in LMTP mode. This meant that they could be retried too
1818 frequently, and not timed out correctly.
1819
1820 (ii) Exim was setting the flag that allows error details to be returned
1821 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1822 recipients that were returned after the DATA command.
1823
1824PH/53 This is related to PH/52, but is more general: for any failing address,
1825 when detailed error information was permitted to be returned to the
1826 sender, but the error was temporary, then after the final timeout, only
1827 "retry timeout exceeded" was returned. Now it returns the full error as

1898PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1899 function verify_get_ident() calls ip_connect() to connect a socket, but
1900 if the "connect()" function timed out, ip_connect() used to close the
1901 socket. However, verify_get_ident() also closes the socket later, and in
1902 between Exim writes to the log, which may get opened at this point. When
1903 the socket was closed in ip_connect(), the log could get the same file
1904 descriptor number as the socket. This naturally causes chaos. The fix is
1905 not to close the socket in ip_connect(); the socket should be closed by
1906 the function that creates it. There was only one place in the code where
1907 this was missing, in the iplookup router, which I don't think anybody now
1908 uses, but I've fixed it anyway.

1937 because their memory is reclaimed, so using them afterwards may do
1938 silly things.

1968 identical. For example:
1969
1970 Received: from [1.2.3.4] (helo=[1.2.3.4])
1971
1972 However, if the real host name was known, it was omitting the HELO data

2000PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2001 Electronic Mail") by including:
2002
2003 Auto-submitted: auto-generated
2004
2005 in the messages that it generates (bounce messages and others, such as
2006 warnings). In the case of bounce messages for non-SMTP mesages, there was
2007 also a typo: it was using "Auto_submitted" (underscore instead of
2008 hyphen). Since every message generated by Exim is necessarily in response
2009 to another message, thes have all been changed to:
2010
2011 Auto-Submitted: auto-replied
2012
2013 in accordance with these statements in the RFC:
2014
2015 The auto-replied keyword:
2016
2017 - SHOULD be used on messages sent in direct response to another
2018 message by an automatic process,
2019
2020 - MUST NOT be used on manually-generated messages,
2021
2022 - MAY be used on Delivery Status Notifications (DSNs) and Message
2023 Disposition Notifications (MDNs),
2024
2025 - MUST NOT be used on messages generated by automatic or periodic
2026 processes, except for messages which are automatic responses to
2027 other messages.

2063PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2064 canonical form (as documented). However, after a host name lookup from
2065 the IP address, check_host() was doing a simple string comparison with
2066 addresses acquired from the DNS when checking that the found name did
2067 have the original IP as one of its addresses. Since any found IPv6
2068 addresses are likely to be in abbreviated form, the comparison could
2069 fail. Luckily, there already exists a function for doing the comparison
2070 by converting both addresses to binary, so now that is used instead of
2071 the text comparison.

PH
2073PH/20 There was another similar case to PH/19, when a complete host name was

2371 preserve the sysexits.h value, by assumimg that macro definitions were

2446PH/15 The code I had for printing potentially long long variables in PH/11

PH
2449 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
2450 to be "long long int" or "long int". This is needed for the internal
2451 formatting function string_vformat().

PH
2453PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
2454 the configuration file to be ":syslog", then the script "guesses" where
2455 the logs files are, rather than using the compiled in default. In our
2456 case the guess is not the same as the compiled default, so the script
2457 suddenly stopped working when I started to use syslog. The patch checks
2458 to see if log_file_path is "". If so, it attempts to read it from exim
2459 with no configuration file to get the compiled in version, before it
2460 falls back to the previous guessing code."

2475 patch removes a few documentation additions to RFC 3028, because the

2477 and a new error check for 8bit text in MIME parts. Comparator and

2503PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints

ff790e47 2508PH/26 Insert a lot of missing (void) casts for functions such as chown(),
f1e894f3
PH
2509 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
2510 picked up on a user's system that detects such things. There doesn't seem
2511 to be a gcc warning option for this - only an attribute that has to be
2512 put on the function's prototype. It seems that in Fedora Core 4 they have
2513 set this on a number of new functions. No doubt there will be more in due
2514 course.

5417f6d1
PH
2516PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
2517 specify a transport. However, if an address that was verified by such a
2518 router was the subject of a callout, Exim crashed because it tried to
2519 read the rcpt_include_affixes from the non-existent transport. Now it
2520 just assumes that the setting of that option is false. This bug was
2521 introduced by 4.51/PH/31.

PH
2531PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
2532 aren't the modern standard, and it seems that some systems' include files
2533 don't always have them. Exim was already checking for some of the newer
2534 ones like T_AAAA, and defining it itself. I've added checks for all the
2535 record types that Exim uses.

182ad5cf
PH
2537PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
2538 not automatically generating a new one, as it is supposed to. This
2539 prevented TLS from working. If the file did exist, but contained invalid
2540 data, a new version was generated, as expected. It was only the case of a
2541 non-existent file that was broken.

2552PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
2553 the use of a port name that isn't defined in /etc/services) occurred, the
2554 message was deferred as in a normal delivery, and thus remained on the
2555 spool, instead of being failed because of the mua_wrapper setting. This
2556 is now fixed, and I tidied up some of the mua_wrapper messages at the
2557 same time.

2559SC/08 Eximstats: whilst parsing the mainlog(s), store information about

2587 to test Sieve filters that use "vacation".
2588
2589PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2590 that changes the way the GnuTLS parameters are stored in the cache file.
2591 The new format can be generated externally. For backward compatibility,
2592 if the data in the cache doesn't make sense, Exim assumes it has read an
2593 old-format file, and it generates new data and writes a new file. This
2594 means that you can't go back to an older release without removing the
2595 file.
2596
2597PH/03 A redirect router that has both "unseen" and "one_time" set does not
2598 work if there are any delivery delays because "one_time" forces the
2599 parent to be marked "delivered", so its unseen clone is never tried
2600 again. For this reason, Exim now forbids the simultaneous setting of
2601 these two options.
2602
2603PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2604 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2605 entry if you want to know the details. The fix, however, neglected to
2606 consider the case when local delivery batching is involved. The test for
2607 "previously delivered" was not happening when checking to see if an
2608 address could be batched with a previous (undelivered) one; under
2609 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2610 address.
1a46a8c5
PH
2611
2612PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
2613 in its include files, and this causes problems building Exim.
2614
2615PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2616 header_syntax) but Exim was just ignoring anything given after a slash.
2617 In particular, this caused confusion with an attempt to use "verify =
2618 reverse_host_lookup/defer_ok". An error is now given when options are
2619 supplied for verify items that do not have them. (Maybe reverse_host_
2620 lookup should have a defer_ok option, but that's a different point.)
2621
2622PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
2623 defined by RFC 821) to 2048, because there were problems with some AUTH
2624 commands, and RFC 1869 says the size should be increased for extended
2625 SMTP commands that take arguments.

PH
2672PH/19 When an Exim process that is running as root has to create an Exim log
2673 file, it does so in a subprocess that runs as exim:exim so as to get the
2674 ownership right at creation (otherwise, other Exim processes might see
2675 the file with the wrong ownership). There was no test for failure of this
2676 fork() call, which would lead to the process getting stuck as it waited
2677 for a non-existent subprocess. Forks do occasionally fail when resources
2678 run out. I reviewed all the other calls to fork(); they all seem to check
2679 for failure.

PH
2681PH/20 When checking for unexpected SMTP input at connect time (before writing
2682 the banner), Exim was not dealing correctly with a non-positive return
2683 from the read() function. If the client had disconnected by this time,
2684 the result was a log entry for a synchronization error with an empty
2685 string after "input=" when read() returned zero. If read() returned -1
2686 (an event I could not check), uninitialized data bytes were printed.

c5ddb310
PH
2698PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2699 hadn't been configured. The fix is from Juergen Kreileder, who
2700 understands it better than I do:
2701
2702 "Here's what I see happening with three configured cyrus_sasl
2703 authenticators configured (plain, login, cram-md5):
2704
2705 On startup auth_cyrus_sasl_init() gets called for each of these.
2706 This means three calls to sasl_listmech() without a specified mech_list.
2707 => SASL tests which mechs of all available mechs actually work
2708 => three warnings about OTP not working
2709 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2710
2711 With the patch, sasl_listmech() also gets called three times. But now
2712 SASL's mech_list option is set to the server_mech specified in the the
2713 authenticator. Or in other words, the answer from sasl_listmech()
2714 gets limited to just the mech you're testing for (which is different
2715 for each call.)
2716 => the return list contains just 'plain' or 'login', 'cram-md5' or
2717 nothing depending on the value of ob->server_mech.
2718
2719 I've just tested the patch: Authentication still works fine,
2720 unavailable mechs specified in the exim configuration are still
2721 caught, and the auth.log warnings about OTP are gone."

PH
2785PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2786 the grounds that routing the same address twice would always produce the
2787 same answer. This might have been true once, but it is certainly no
2788 longer true now. Routing a child address may depend on the previous
2789 routing that produced that child. Some complicated redirection strategies
2790 went wrong when messages had multiple recipients, and made Exim's
2791 behaviour dependent on the order in which the addresses were given.
2792
2793 I have moved the duplicate checking until after the routing is complete.
2794 Exim scans the addresses that are assigned to local and remote
2795 transports, and removes any duplicates. This means that more work will be
2796 done, as duplicates will always all be routed, but duplicates are
2797 presumably rare, so I don't expect this is of any significance.
2798
2799 For deliveries to pipes, files, and autoreplies, the duplicate checking
2800 still happens during the routing process, since they are not going to be
2801 routed further.

2803PH/38 Installed a patch from Ian Freislich, with the agreement of Tom Kistner.
2804 It corrects a timeout issue with spamd. This is Ian's comment: "The
2805 background is that sometimes spamd either never reads data from a
2806 connection it has accepted, or it never writes response data. The exiscan
2807 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
2808 blindly assumes that writes won't block so it may never time out."

2822PH/42 Exim no longer gives details of delivery errors for specific addresses in
2823 bounce and delay warning messages, except in certain special cases, which

2827 (b) A message specified in a :fail: redirection;
2828 (c) A message specified in a "fail" command in a system filter;
2829 (d) A message specified in a FAIL return from the queryprogram router;
2830 (e) A message specified by the cannot_route_message router option.
2831
2832 In these cases only, Exim does include the error details in bounce and
2833 warning messages. There are also a few cases where bland messages such
2834 as "unrouteable address" or "local delivery error" are given.

2845 successful delivery. Such timeouts include transport filter timeouts. For
2846 consistency with the overall process timeout, these timeouts are now
2847 treated as errors, giving rise to delivery failures by default. However,
2848 there is now a new Boolean option for the pipe transport called
2849 timeout_defer, which, if set TRUE, converts the failures into defers for
2850 both kinds of timeout. A transport filter timeout is now identified in

2860A note about Exim versions 4.44 and 4.50
2861----------------------------------------
2862
2863Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2864changes of various kinds. As a consequence, a big documentation update was
2865needed. This delayed the release for rather longer than seemed good, especially
2866in the light of a couple of (minor) security issues. Therefore, the changes
2867that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2868release. So 4.44 and 4.50 are in effect two different branches that both start
2869from 4.43.
2870
2871I have left the 4.50 change log unchanged; it contains all the changes since
28724.43. The change log for 4.44 is below; many of its items are identical to
2873those for 4.50. This seems to be the most sensible way to preserve the
2874historical information.

2880 1. Minor wording change to the doc/README.SIEVE file.

PH
2892 5. There are several places where Exim runs a non-Exim command in a
2893 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2894 was being done only for the command run by the queryprogram router. It is
2895 now done for all such subprocesses. The other cases are: ${run, transport
2896 filters, and the commands run by the lmtp and pipe transports.

2898 6. Added CONFIGURE_GROUP build-time option.
2899
2900 7. Some older OS have a limit of 256 on the maximum number of file
2901 descriptors. Exim was using setrlimit() to set 1000 as a large value
2902 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2903 systems. I've change it so that if it can't get 1000, it tries for 256.

2905 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
2906 was an oversight, and furthermore, ever since the addition of extra
2907 controls (e.g. 4.43/32), the checks on when to allow different forms of
2908 "control" were broken. There should now be diagnostics for all cases when a
2909 control that does not make sense is encountered.

292012. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
2921 of $address_data from the recipient verification was clobbered by the
2922 sender verification.

295022. $host_address is now set to the target address during the checking of
2951 ignore_target_hosts.
2952
295323. When checking ignore_target_hosts for an ipliteral router, no host name was
2954 being passed; this would have caused $sender_host_name to have been used if
2955 matching the list had actually called for a host name (not very likely,
2956 since this list is usually IP addresses). A host name is now passed as
2957 "[x.x.x.x]".
2958
7d468ab8
PH
295924. Changed the calls that set up the SIGCHLD handler in the daemon to use the
2960 code that specifies a non-restarting handler (typically sigaction() in
2961 modern systems) in an attempt to fix a rare and obscure crash bug.
2962
296325. Narrowed the window for a race in the daemon that could cause it to ignore
2964 SIGCHLD signals. This is not a major problem, because they are used only to
2965 wake it up if nothing else does.
2966
62c0818f
PH
296726. A malformed maildirsize file could cause Exim to calculate negative values
2968 for the mailbox size or file count. Odd effects could occur as a result.
2969 The maildirsize information is now recalculated if the size or filecount
2970 end up negative.
2971
26034054
PH

PH
297729. In an address list, if the pattern was not a regular expression, an empty
2978 subject address (from a bounce message) matched only if the pattern was an
2979 empty string. Non-empty patterns were not even tested. This was the wrong
2980 because it is perfectly reasonable to use an empty address as part of a
2981 database query. An empty address is now tested by patterns that are
2982 lookups. However, all the other forms of pattern expect the subject to
2983 contain a local part and a domain, and therefore, for them, an empty
2984 address still always fails if the pattern is not itself empty.
2985
d8ef3577
PH
298630. Exim went into a mad DNS loop when attempting to do a callout where the
2987 host was specified on an smtp transport, and looking it up yielded more
2988 than one IP address.
2989
5cb8cbc6
PH
299031. Re-factored the code for checking spool and log partition space into a
2991 function that finds that data and another that does the check. The former
2992 is then used to implement four new variables: $spool_space, $log_space,
2993 $spool_inodes, and $log_inodes.
2994

PH
299532. The RFC2047 encoding function was originally intended for short strings
2996 such as real names; it was not keeping to the 75-character limit for
2997 encoded words that the RFC imposes. It now respects the limit, and
2998 generates multiple encoded words if necessary. To be on the safe side, I
2999 have increased the buffer size for the ${rfc2047: expansion operator from
3000 1024 to 2048 bytes.
3001
063b1e99
PH
300233. It is now permitted to omit both strings after an "if" condition; if the
3003 condition is true, the result is "true". As before, when the second string
3004 is omitted, a false condition yields an empty string. This makes it less
3005 cumbersome to write custom ACL and router conditions.
3006
652e1b65
PH
300734. Failure to deliver a bounce message always caused it to be frozen, even if
3008 there was an errors_to setting on the router. The errors_to setting is now
3009 respected.
3010
6f0c9a4f
PH
301135. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3012 canonical form (fully expanded) before being placed in
3013 $sender_host_address.
3014
33397d19
PH
301536. The table in the code that translates DNS record types into text (T_A to
3016 "A" for instance) was missing entries for NS and CNAME. It is just possible
3017 that this could have caused confusion if both these types were looked up
3018 for the same domain, because the text type is used as part of Exim's
3019 per-process caching. But the chance of anyone hitting this buglet seems
3020 very small.
3021
7bb56e1f
PH
302237. The dnsdb lookup has been extended in a number of ways.
3023
3024 (1) There is a new type, "zns", which walks up the domain tree until it
3025 finds some nameserver records. It should be used with care.
3026
ea3bc19b
PH
3027 (2) There is a new type, "mxh", which is like "mx" except that it returns
3028 just the host names, not the priorities.
3029
3030 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19

3031 looked up. The behaviour when one of the lookups defers can be
3032 controlled by a keyword.
7bb56e1f 3033
ea3bc19b 3034 (4) It is now possible to specify the separator character for use when
7bb56e1f 3035 multiple records are returned.

3039 domain.

3058 < 0 before doing a fflush(). This bug looks as though it goes back to the

308452. Exim crashed if a remote delivery caused a very long error message to be
3085 recorded - for instance if somebody sent an entire SpamAssassin report back
3086 as a large number of 550 error lines. This bug was coincidentally fixed by
3087 increasing the size of one of Exim's internal buffers (big_buffer) that
3088 happened as part of the Exiscan merge. However, to be on the safe side, I
3089 have made the code more robust (and fixed the comments that describe what
3090 is going on).

PH
309754. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3098 patch that reportedly fixes this has been added. I am not expert enough to
3099 create a test for it. This is what the patch creator wrote:
3100
3101 "I found a little strange behaviour of ldap code when working with
3102 Windows 2003 AD Domain, where users was placed in more than one
3103 Organization Units. When I tried to give exim partial DN, the exit code
3104 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3105 But simultaneously result of request was absolutely normal ldap result,
3106 so I produce this patch..."
3107
3295e65b
PH
3108 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3109 REFERENCE, so I have modified the code to exclude the patch when that macro
3110 is not defined.

3113 keys for these records are domain names, not reversed IP addresses. The

3114 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3115 leaves it alone. Component reversal etc. now happens only for IP addresses.

3127

3129 (2) The default for smtp_banner uses $smtp_active_hostname instead
3130 of $primary_hostname.

b975ba52
PH
313260. The host_aton() function is supposed to be passed a string that is known
3133 to be a valid IP address. However, in the case of IPv6 addresses, it was
3134 not checking this. This is a hostage to fortune. Exim now panics and dies
3135 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3136 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3137 components; fortuitously, this particular loophole had already been fixed
3138 by change 4.50/55 above.
3139
3140 If there are any other similar loopholes, the new check in host_aton()
3141 itself should stop them being exploited. The report I received stated that
3142 data on the command line could provoke the exploit when Exim was running as
3143 exim, but did not say which command line option was involved. All I could
3144 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3145 running as the user.

3157 need the first call to be done as root, but it missed one case: when
3158 deliver_queue_load_max is set with deliver_drop_privilege. This is

3167 consequently, it could be overwritten for a subsequent message in the same
3168 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3169 the caching.)
3170

PH
317166. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3172
a5a28604
PH
317367. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3174 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3175 the function were treating the return as a boolean value, which happened to
3176 work because 0=false and not-0=true, but is not correct code.
3177
7e634d24
PH
317868. The host_aton() function was not handling scoped IPv6 addresses (those
3179 with, for example, "%eth0" on the end) correctly.
3180
3e11c26b
PH
318169. Fixed some compiler warnings in acl.c for the bitmaps specified with
3182 negated items (that is, ~something) in unsigned ints. Some compilers
3183 apparently mutter when there is no cast.
3184
6729cf78
PH
318570. If an address verification called from an ACL failed, and did not produce a
3186 user-specific message (i.e. there was only a "system" message), nothing was
3187 put in $acl_verify_message. In this situation, it now puts the system
3188 message there.
3189
00f00ca5
PH
319071. Change 4.23/11 added synchronization checking at the start of an SMTP
3191 session; change 4.31/43 added the unwanted input to the log line - except
3192 that it did not do this in the start of session case. It now does.
3193
c9bdd01c
PH
319472. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3195 This is wrong and can cause the other end to generate a synchronization
3196 error if it is another Exim or anything else that does the synchronization
3197 check. A QUIT command is no longer sent after a timeout.
3198
d43194df
PH
319973. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3200 during host lookups.
3201
fe5b5d0b
PH
320274. The defer_ok option of callout verification was not working if it was used
3203 when verifying addresses in header lines, that is, for this case:
3204
3205 verify = header_sender/callout=defer_ok
3206
76a2d7ba
PH
320775. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3208 those file descriptors could be used for SMTP connections. If anything
3209 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3210 could be sent to the SMTP client, causing chaos. The daemon now opens
3211 stdin, stdout, and stderr to /dev/null when it puts itself into the
3212 background.
3213
321476. Arrange for output from Perl's "warn" command to be written to Exim's main
3215 log by default. The user can override this with suitable Perl magic.
3216
04f7d5b9
PH
321777. The use of log_message on a "discard" ACL verb, which is supposed to add to
3218 the log message when discard triggers, was not working for the DATA ACL or
3219 for the non-SMTP ACL.
3220
bc60667e
PH
322178. Error message wording change in sieve.c.
3222
bb6e88ff
PH
322379. If smtp_accept_max_per_host was set, the number of connections could be
3224 restricted to fewer than expected, because the daemon was trying to set up
3225 a new connection before checking whether the processes handling previous
3226 connections had finished. The check for completed processes is now done
3227 earlier. On busy systems, this bug wouldn't be noticed because something
3228 else would have woken the daemon, and it would have reaped the completed
3229 process earlier.
3230
1e70f85b
PH
323180. If a message was submitted locally by a user whose login name contained one
3232 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3233 It caused a spool format error. I have fixed the spool reading code. A
3234 related problem was that the "from" clause in the Received: line became
3235 illegal because of the space(s). It is now covered by ${quote_local_part.
3236
323781. Included the latest eximstats from Steve (adds average sizes to HTML Top
3238 tables).
3239

324082. Updated OS/Makefile-AIX as per message from Mike Meredith.

3251----------------------------------------------------
3252See the note above about the 4.44 and 4.50 releases.
3253----------------------------------------------------
3254
3255
3256Exim version 4.44
3257-----------------
3258
3259 1. Change 4.43/35 introduced a bug that caused file counts to be
3260 incorrectly computed when quota_filecount was set in an appendfile
3261 transport
3262
3263 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3264 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3265 place.
3266
3267 3. Give more explanation in the error message when the command for a transport
3268 filter fails to execute.
3269
3270 4. There are several places where Exim runs a non-Exim command in a
3271 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3272 was being done only for the command run by the queryprogram router. It is
3273 now done for all such subprocesses. The other cases are: ${run, transport
3274 filters, and the commands run by the lmtp and pipe transports.
3275
3276 5. Some older OS have a limit of 256 on the maximum number of file
3277 descriptors. Exim was using setrlimit() to set 1000 as a large value
3278 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3279 systems. I've change it so that if it can't get 1000, it tries for 256.
3280
3281 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3282 was an oversight, and furthermore, ever since the addition of extra
3283 controls (e.g. 4.43/32), the checks on when to allow different forms of
3284 "control" were broken. There should now be diagnostics for all cases when a
3285 control that does not make sense is encountered.
3286
3287 7. $recipients is now available in the predata ACL (oversight).
3288
3289 8. Tidy the search cache before the fork to do a delivery from a message
3290 received from the command line. Otherwise the child will trigger a lookup
3291 failure and thereby defer the delivery if it tries to use (for example) a
3292 cached ldap connection that the parent has called unbind on.
3293
3294 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3295 of $address_data from the recipient verification was clobbered by the
3296 sender verification.
3297
329810. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3299 was its contents. (It was OK if the option was not defined at all.)
3300
330111. A "Completed" log line is now written for messages that are removed from
3302 the spool by the -Mrm option.
3303
330412. $host_address is now set to the target address during the checking of
3305 ignore_target_hosts.
3306
330713. When checking ignore_target_hosts for an ipliteral router, no host name was
3308 being passed; this would have caused $sender_host_name to have been used if
3309 matching the list had actually called for a host name (not very likely,
3310 since this list is usually IP addresses). A host name is now passed as
3311 "[x.x.x.x]".
3312
331314. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3314 code that specifies a non-restarting handler (typically sigaction() in
3315 modern systems) in an attempt to fix a rare and obscure crash bug.
3316
331715. Narrowed the window for a race in the daemon that could cause it to ignore
3318 SIGCHLD signals. This is not a major problem, because they are used only to
3319 wake it up if nothing else does.
3320
332116. A malformed maildirsize file could cause Exim to calculate negative values
3322 for the mailbox size or file count. Odd effects could occur as a result.
3323 The maildirsize information is now recalculated if the size or filecount
3324 end up negative.
3325
332617. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3327 support for a long time. Removed HAVE_SYS_VFS_H.
3328
ea3a6f44 332918. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3330
333119. Allow an empty sender to be matched against a lookup in an address list.
3332 Previously the only cases considered were a regular expression, or an
3333 empty pattern.
3334
333520. Exim went into a mad DNS lookup loop when doing a callout where the
3336 host was specified on the transport, if the DNS lookup yielded more than
3337 one IP address.
3338
ea3a6f44
NM
333921. The RFC2047 encoding function was originally intended for short strings
3340 such as real names; it was not keeping to the 75-character limit for
3341 encoded words that the RFC imposes. It now respects the limit, and
3342 generates multiple encoded words if necessary. To be on the safe side, I
3343 have increased the buffer size for the ${rfc2047: expansion operator from
3344 1024 to 2048 bytes.
bbe902f0 3345
ea3a6f44
NM
334622. Failure to deliver a bounce message always caused it to be frozen, even if
3347 there was an errors_to setting on the router. The errors_to setting is now
3348 respected.
bbe902f0
PH
3349
335023. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3351 canonical form (fully expanded) before being placed in
3352 $sender_host_address.
3353
335424. Updated eximstats to version 1.33
3355
ea3a6f44
NM
335625. Include certificate and key file names in error message when GnuTLS fails
3357 to set them up, because the GnuTLS error message doesn't include the name
3358 of the failing file when there is a problem reading it.
bbe902f0
PH
3359
336026. Expand error message when OpenSSL has problems setting up cert/key files.
ea3a6f44 3361 As per change 25.
bbe902f0 3362
ea3a6f44
NM
336327. Reset the locale to "C" after calling embedded Perl, in case it was changed
3364 (this can affect the format of dates).
bbe902f0 3365
ea3a6f44
NM
336628. exim_tidydb, when checking for the continued existence of a message for
3367 which it has found a message-specific retry record, was not finding
3368 messages that were in split spool directories. Consequently, it was
3369 deleting retry records that should have stayed in existence.
bbe902f0
PH
3370
337129. eximstats updated to version 1.35
3372 1.34 - allow eximstats to parse syslog lines as well as mainlog lines
3373 1.35 - bugfix such that pie charts by volume are generated correctly
3374
ea3a6f44
NM
337530. The SPA authentication driver was not abandoning authentication and moving
3376 on to the next authenticator when an expansion was forced to fail,
3377 contradicting the general specification for all authenticators. Instead it
3378 was generating a temporary error. It now behaves as specified.
bbe902f0 3379
ea3a6f44
NM
338031. The default ordering of permitted cipher suites for GnuTLS was pessimal
3381 (the order specifies the preference for clients). The order is now AES256,
3382 AES128, 3DES, ARCFOUR128.
bbe902f0 3383
ea3a6f44
NM
338431. Small patch to Sieve code - explicitly set From: when generating an
3385 autoreply.
bbe902f0 3386
ea3a6f44
NM
338732. Exim crashed if a remote delivery caused a very long error message to be
3388 recorded - for instance if somebody sent an entire SpamAssassin report back
3389 as a large number of 550 error lines. This bug was coincidentally fixed by
3390 increasing the size of one of Exim's internal buffers (big_buffer) that
3391 happened as part of the Exiscan merge. However, to be on the safe side, I
3392 have made the code more robust (and fixed the comments that describe what
3393 is going on).
bbe902f0 3394
ea3a6f44
NM
339533. Some experimental protocols are using DNS PTR records for new purposes. The
3396 keys for these records are domain names, not reversed IP addresses. The
3397 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3398 leaves it alone. Component reversal etc. now happens only for IP addresses.
bbe902f0
PH
3399 CAN-2005-0021
3400
ea3a6f44
NM
340134. The host_aton() function is supposed to be passed a string that is known
3402 to be a valid IP address. However, in the case of IPv6 addresses, it was
3403 not checking this. This is a hostage to fortune. Exim now panics and dies
3404 if the condition is not met. A case was found where this could be provoked
3405 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3406 components; fortuitously, this particular loophole had already been fixed
3407 by change 4.50/55 or 4.44/33 above.
3408
3409 If there are any other similar loopholes, the new check in host_aton()
3410 itself should stop the
