TF
43TF/03 Make the exiwhat support code safe for signals. Previously Exim might
44 lock up or crash if it happened to be inside a call to libc when it
45 got a SIGUSR1 from exiwhat.
46
47 The SIGUSR1 handler appends the current process status to the process
48 log which is later printed by exiwhat. It used to use the general
49 purpose logging code to do this, but several functions it calls are
50 not safe for signals.
51
52 The new output code in the SIGUSR1 handler is specific to the process
53 log, and simple enough that it's easy to inspect for signal safety.
54 Removing some special cases also simplifies the general logging code.
55 Removing the spurious timestamps from the process log simplifies
56 exiwhat.
57

TF
58TF/04 Improved ratelimit ACL condition.
59
60 The /noupdate option has been deprecated in favour of /readonly which
61 has clearer semantics. The /leaky, /strict, and /readonly update modes
62 are mutually exclusive. The update mode is no longer included in the
63 database key; it just determines when the database is updated. (This
64 means that when you upgrde Exim will forget old rate measurements.)
65
66 Exim now checks that the per_* options are used with an update mode that
67 makes sense for the current ACL. For example, when Exim is processing a
68 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
69 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
70 must specify per_mail/readonly. If you omit the update mode it defaults to
71 /leaky where that makes sense (as before) or /readonly where required.
72
73 The /noupdate option is now undocumented but still supported for
74 backwards compatibility. It is equivalent to /readonly except that in
75 ACLs where /readonly is required you may specify /leaky/noupdate or
76 /strict/noupdate which are treated the same as /readonly.
77
78 A useful new feature is the /count= option. This is a generalization
79 of the per_byte option, so that you can measure the throughput of other
80 aggregate values. For example, the per_byte option is now equivalent
81 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
82
83 The per_rcpt option has been generalized using the /count= mechanism
84 (though it's more complicated than the per_byte equivalence). When it is
85 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
86 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
87 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
88 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
89 Note that using per_rcpt with a non-readonly update mode in more than
90 one ACL will cause the recipients to be double-counted. (The per_mail
91 and per_byte options don't have this problem.)
92
93 The handling of very low rates has changed slightly. If the computed rate
94 is less than the event's count (usually one) then this event is the first
95 after a long gap. In this case the rate is set to the same as this event's
96 count, so that the first message of a spam run is counted properly.
97
98 The major new feature is a mechanism for counting the rate of unique
99 events. The new per_addr option counts the number of different
100 recipients that someone has sent messages to in the last time period. It
101 behaves like per_rcpt if all the recipient addresses are different, but
102 duplicate recipient addresses do not increase the measured rate. Like
103 the /count= option this is a general mechanism, so the per_addr option
104 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
105 example, measure the rate that a client uses different sender addresses
106 with the options per_mail/unique=$sender_address. There are further
107 details in the main documentation.

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

679PH/01 Another patch from the Sieve maintainer.
680
6a3bceb1
PH
681PH/02 When an IPv6 address is converted to a string for single-key lookup
682 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
683 dots are used instead of colons so that keys in lsearch files need not
684 contain colons. This was done some time before quoting was made available
685 in lsearch files. However, iplsearch files do require colons in IPv6 keys
686 (notated using the quote facility) so as to distinguish them from IPv4
687 keys. This meant that lookups for IP addresses in host lists did not work
688 for iplsearch lookups.
689
690 This has been fixed by arranging for IPv6 addresses to be expressed with
691 colons if the lookup type is iplsearch. This is not incompatible, because
692 previously such lookups could never work.
693
694 The situation is now rather anomolous, since one *can* have colons in
695 ordinary lsearch keys. However, making the change in all cases is
696 incompatible and would probably break a number of configurations.

701MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
702 conversion specification without a maximum field width, thereby enabling
703 a rogue spamd server to cause a buffer overflow. While nobody in their
704 right mind would setup Exim to query an untrusted spamd server, an
705 attacker that gains access to a server running spamd could potentially
706 exploit this vulnerability to run arbitrary code as the Exim user.

MH
711MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
712 a directory entry by the name of the lookup key. Previously, if a
713 symlink pointed to a non-existing file or a file in a directory that
714 Exim lacked permissions to read, a lookup for a key matching that
715 symlink would fail. Now it is enough that a matching directory entry
716 exists, symlink or not. (Bugzilla 503.)

PH
899PH/29 SMTP synchronization checks are implemented when a command is read -
900 there is a check that no more input is waiting when there shouldn't be
901 any. However, for some commands, a delay in an ACL can mean that it is
902 some time before the response is written. In this time, more input might
903 arrive, invalidly. So now there are extra checks after an ACL has run for
904 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
905 pipelining has not been advertised.

920 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
921 was a macro that became an assignment, so it seemed to work. This has
922 changed to a proper function call with a void return, hence the compile
923 error. Exim's code has been fixed.

951PH/40 When Exim receives a message, it writes the login name, uid, and gid of

954 started the daemon, but after a SIGHUP it used the Exim user (because it
955 calls itself on a restart). I have changed the code so that it now always
956 uses the Exim user.

58eb016e 978PH/44 I found a way to check for a TCP/IP connection going away before sending

PH
979 the response to the final '.' that terminates a message, but only in the
980 case where the client has not sent further data following the '.'
981 (unfortunately, this is allowed). However, in many cases there won't be
982 any further data because there won't be any more messages to send. A call
983 to select() can be used: if it shows that the input is "ready", there is
984 either input waiting, or the socket has been closed. An attempt to read
985 the next input character can distinguish the two cases. Previously, Exim
58eb016e 986 would have sent an OK response which the client would never have see.

996
997PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
998 fixed by 4.65/MH/01 (is this a record?) are fixed:
999
1000 (i) An empty string was always treated as zero by the numeric comparison
1001 operators. This behaviour has been restored.
1002
1003 (ii) It is documented that the numeric comparison operators always treat
1004 their arguments as decimal numbers. This was broken in that numbers
1005 starting with 0 were being interpreted as octal.
1006
1007 While fixing these problems I realized that there was another issue that
1008 hadn't been noticed. Values of message_size_limit (both the global option
1009 and the transport option) were treated as octal if they started with 0.
1010 The documentation was vague. These values are now always treated as
1011 decimal, and I will make that clear in the documentation.

1025PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1026 child addresses, Exim now panics and dies. Previously, because the count
1027 is held in a short int, deliveries were likely to be lost. As such a
1028 large number of recipients for a single message is ridiculous
1029 (performance will be very, very poor), I have chosen to impose a limit
1030 rather than extend the field.

1036TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1037 leftover -K file (the existence of which was triggered by #402).

1042TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1043 processing considerably. Previous code took too long for large mails,
1044 triggering a timeout which in turn triggers #401.
1045
1046TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1047 in the DK code in transports.c. sendfile() is not really portable,

2b1c6e3a
PH
1055PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1056 callout verification, Exim cached a "reject" for the entire domain. This
1057 is correct for most verifications, but it is not correct for a recipient
1058 verification with use_sender or use_postmaster set, because in that case
1059 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1060 case of MAIL FROM:<> rejection from other early rejections (e.g.
1061 rejection of HELO). When verifying a recipient using a non-null MAIL
1062 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1063 Whatever the result of the callout, the value of the domain cache is
1064 left unchanged (for any other kind of callout, getting as far as trying
1065 RCPT means that the domain itself is ok).

1099PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1100 hostname. This is wrong, because it relates to the incoming message (and
1101 probably the interface on which it is arriving) and not to the outgoing
1102 callout (which could be using a different interface). This has been
1103 changed to use the value of the helo_data option from the smtp transport
1104 instead - this is what is used when a message is actually being sent. If
1105 there is no remote transport (possible with a router that sets up host
1106 addresses), $smtp_active_hostname is used.

14aa5a05 1108PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1109 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1110 (a) The code assumed that strncpy() returns a negative number on buffer
1111 overflow, which isn't the case. Replaced with Exim's string_format()
1112 function.
1113 (b) There were several signed/unsigned issues. I just did the minimum
1114 hacking in of casts. There is scope for a larger refactoring.
1115 (c) The code used strcasecmp() which is not a standard C function.
1116 Replaced with Exim's strcmpic() function.
1117 (d) The code set only $1; it now sets $auth1 as well.
1118 (e) A simple test gave the error "authentication client didn't specify
1119 service in request". It would seem that Dovecot has changed its
1120 interface. Fortunately there's a specification; I followed it and
1121 changed what the client sends and it appears to be working now.

1126PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1127 address A is aliased to B and C, where B exists and C does not. Without
1128 -v the output is "A verified" because verification stops after a
1129 successful redirection if more than one address is generated. However,
1130 with -v the child addresses are also verified. Exim was outputting "A
1131 failed to verify" and then showing the successful verification for C,
1132 with its parentage. It now outputs "B failed to verify", showing B's
1133 parentage before showing the successful verification of C.

1136 look up a TXT record in a specific list after matching in a combined
1137 list.
1138
322050c2
PH
1139PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1140 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1141 they consult the DNS. I had assumed they would set it the way they
1142 wanted; and indeed my experiments on Linux seem to show that in some
1143 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1144 To be on the safe side, however, I have now made the interface to
1145 host_find_byname() similar to host_find_bydns(), with an argument
1146 containing the DNS resolver options. The host_find_byname() function now
1147 sets these options at its start, just as host_find_bydns() does. The smtp
1148 transport options dns_qualify_single and dns_search_parents are passed to
1149 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1150 of host_find_byname() use the default settings of RES_DEFNAMES
1151 (qualify_single) but not RES_DNSRCH (search_parents).

1153PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1154 spool_read_header() do less string testing, by means of a preliminary
1155 switch on the second character of optional "-foo" lines. (This is
1156 overdue, caused by the large number of possibilities that now exist.
1157 Originally there were few.) While I was there, I also converted the
1158 str(n)cmp tests so they don't re-test the leading "-" and the first
1159 character, in the hope this might squeeze out yet more improvement.

1161PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1162 flag allowing group syntax was set by the header_syntax check but not
1163 turned off, possible causing trouble later; (2) The flag was not being
1164 set at all for the header_verify test, causing "group"-style headers to
1165 be rejected. I have now set it in this case, and also caused header_
1166 verify to ignore an empty address taken from a group. While doing this, I
1167 came across some other cases where the code for allowing group syntax
1168 while scanning a header line wasn't quite right (mostly, not resetting
1169 the flag correctly in the right place). These bugs could have caused
1170 trouble for malformed header lines. I hope it is now all correct.

PH
1172PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1173 with the "reply" argument non-NULL. The code, however (which originally
1174 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1175 but it didn't always do it. This confused somebody who was copying the
1176 code for some other use. I have removed all the tests.

PH
1178PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1179 feature that was used to support insecure browsers during the U.S. crypto
1180 embargo. It requires special client support, and Exim is probably the
1181 only MTA that supported it -- and would never use it because real RSA is
1182 always available. This code has been removed, because it had the bad
1183 effect of slowing Exim down by computing (never used) parameters for the
1184 RSA_EXPORT functionality.

1187 authenticator to fail if there's a tab character in the incoming data

1189 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1190 if the connection is using TLS or if the remote IP is the same as the
1191 local IP, and the "valid-client-cert option" if a client certificate has
1192 been verified.

1224PH/30 Exim was sometimes attempting to deliver messages that had suffered
1225 address errors (4xx response to RCPT) over the same connection as other
1226 messages routed to the same hosts. Such deliveries are always "forced",
1227 so retry times are not inspected. This resulted in far too many retries
1228 for the affected addresses. The effect occurred only when there were more
1229 hosts than the hosts_max_try setting in the smtp transport when it had
1230 the 4xx errors. Those hosts that it had tried were not added to the list
1231 of hosts for which the message was waiting, so if all were tried, there
1232 was no problem. Two fixes have been applied:
1233
1234 (i) If there are any address or message errors in an SMTP delivery, none
1235 of the hosts (tried or untried) are now added to the list of hosts
1236 for which the message is waiting, so the message should not be a
1237 candidate for sending over the same connection that was used for a
1238 successful delivery of some other message. This seems entirely
1239 reasonable: after all the message is NOT "waiting for some host".
1240 This is so "obvious" that I'm not sure why it wasn't done
1241 previously. Hope I haven't missed anything, but it can't do any
1242 harm, as the worst effect is to miss an optimization.
1243
1244 (ii) If, despite (i), such a delivery is accidentally attempted, the
1245 routing retry time is respected, so at least it doesn't keep
1246 hammering the server.

1262 written to the panic log as well as the main log, but it isn't really

1264 removed the panic log writing for the ECONNRESET error when getsockname()
1265 fails.

48c7f9e2
PH
1267PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1268 runs only) independently of the message's sender address. This meant
1269 that, if the 4xx error was in fact related to the sender, a different
1270 message to the same recipient with a different sender could confuse
1271 things. In particualar, this can happen when sending to a greylisting
1272 server, but other circumstances could also provoke similar problems.
1273 I have changed the default so that the retry time for these errors is now
1274 based a combination of the sender and recipient addresses. This change
1275 can be overridden by setting address_retry_include_sender=false in the
1276 smtp transport.

1549 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1550 554 error is used if errno is still zero or contains ENOENT (which occurs

1592 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1593 that it would not match correctly against @[] and not recognize the IPv6
1594 addresses as local.

1637 autoreply, Exim could try to deliver to a non-existent relative file

1661 in a subprocess such as that created by queryprogram now generate
1662 suitable debugging ouput when -d is set.

1672 additional section of a DNS packet that returns MX or SRV records.
1673 Instead, it always explicitly searches for A/AAAA records. This avoids
1674 major problems that occur when a DNS server includes only records of one
1675 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1676 fixed another bug: if SRV records were looked up and the corresponding
1677 address records were *not* found in the additional section, the port
1678 values from the SRV records were lost.

PH
1688PH/19 When calculating a retry time, Exim used to measure the "time since
1689 failure" by looking at the "first failed" field in the retry record. Now
1690 it does not use this if it is later than than the arrival time of the
1691 message. Instead it uses the arrival time. This makes for better
1692 behaviour in cases where some deliveries succeed, thus re-setting the
1693 "first failed" field. An example is a quota failure for a huge message
1694 when small messages continue to be delivered. Without this change, the
1695 "time since failure" will always be short, possible causing more frequent
1696 delivery attempts for the huge message than are intended.

PH
1793PH/42 The content-scanning code uses fopen() to create files in which to put
1794 message data. Previously it was not paying any attention to the mode of
1795 the files. Exim runs with umask(0) because the rest of the code creates
1796 files with open(), and sets the required mode explicitly. Thus, these
1797 files were ending up world-writeable. This was not a big issue, because,
1798 being within the spool directory, they were not world-accessible. I have
1799 created a function called modefopen, which takes an additional mode
1800 argument. It sets umask(777), creates the file, chmods it to the required
1801 mode, then resets the umask. All the relevant calls to fopen() in the
1802 content scanning code have been changed to use this function.

1814 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

1839
1840 (i) Exim was not creating retry information for temporary errors given
1841 for individual recipients after the DATA command when the smtp transport
1842 was used in LMTP mode. This meant that they could be retried too
1843 frequently, and not timed out correctly.
1844
1845 (ii) Exim was setting the flag that allows error details to be returned
1846 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1847 recipients that were returned after the DATA command.
1848
1849PH/53 This is related to PH/52, but is more general: for any failing address,
1850 when detailed error information was permitted to be returned to the
1851 sender, but the error was temporary, then after the final timeout, only
1852 "retry timeout exceeded" was returned. Now it returns the full error as

1923PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1924 function verify_get_ident() calls ip_connect() to connect a socket, but
1925 if the "connect()" function timed out, ip_connect() used to close the
1926 socket. However, verify_get_ident() also closes the socket later, and in
1927 between Exim writes to the log, which may get opened at this point. When
1928 the socket was closed in ip_connect(), the log could get the same file
1929 descriptor number as the socket. This naturally causes chaos. The fix is
1930 not to close the socket in ip_connect(); the socket should be closed by
1931 the function that creates it. There was only one place in the code where
1932 this was missing, in the iplookup router, which I don't think anybody now
1933 uses, but I've fixed it anyway.

1989PH/06 When a client host used a correct literal IP address in a HELO or EHLO
1990 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
1991 not being looked up in the rDNS to get a host name, Exim was showing the
1992 IP address twice in Received: lines, even though the IP addresses were
1993 identical. For example:
1994
1995 Received: from [1.2.3.4] (helo=[1.2.3.4])
1996
1997 However, if the real host name was known, it was omitting the HELO data
1998 if it matched the actual IP address. This has been tidied up so that it
1999 doesn't show the same IP address twice.

2025PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2026 Electronic Mail") by including:
2027
2028 Auto-submitted: auto-generated
2029
2030 in the messages that it generates (bounce messages and others, such as
2031 warnings). In the case of bounce messages for non-SMTP mesages, there was
2032 also a typo: it was using "Auto_submitted" (underscore instead of
2033 hyphen). Since every message generated by Exim is necessarily in response
2034 to another message, thes have all been changed to:
2035
2036 Auto-Submitted: auto-replied
2037
2038 in accordance with these statements in the RFC:
2039
2040 The auto-replied keyword:
2041
2042 - SHOULD be used on messages sent in direct response to another
2043 message by an automatic process,
2044
2045 - MUST NOT be used on manually-generated messages,
2046
2047 - MAY be used on Delivery Status Notifications (DSNs) and Message
2048 Disposition Notifications (MDNs),

2088PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2089 canonical form (as documented). However, after a host name lookup from
2090 the IP address, check_host() was doing a simple string comparison with
2091 addresses acquired from the DNS when checking that the found name did
2092 have the original IP as one of its addresses. Since any found IPv6
2093 addresses are likely to be in abbreviated form, the comparison could
2094 fail. Luckily, there already exists a function for doing the comparison
2095 by converting both addresses to binary, so now that is used instead of
2096 the text comparison.

PH
2393PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2394 with the definition in sysexits.h (which is #included earlier).
2395 Fortunately, Exim does not actually use EX_OK. The code used to try to
2396 preserve the sysexits.h value, by assumimg that macro definitions were
2397 scanned for macro replacements. I have been disabused of this notion,
2398 so now the code just undefines EX_OK before #including unistd.h.

PH
2400PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
2401 in the smtp transport. When a block could not be written in a single
2402 write() function, the timeout was being re-applied to each part-write.
2403 This seems wrong - if the receiver was accepting one byte at a time it
2404 would take for ever. The timeout is now adjusted when this happens. It
2405 doesn't have to be particularly precise.

2471PH/15 The code I had for printing potentially long long variables in PH/11

PH
2474 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T

PH
2478PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
2479 the configuration file to be ":syslog", then the script "guesses" where
2480 the logs files are, rather than using the compiled in default. In our
2481 case the guess is not the same as the compiled default, so the script
2482 suddenly stopped working when I started to use syslog. The patch checks
2483 to see if log_file_path is "". If so, it attempts to read it from exim
2484 with no configuration file to get the compiled in version, before it
2485 falls back to the previous guessing code."

2528PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints

2534 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
2535 picked up on a user's system that detects such things. There doesn't seem
2536 to be a gcc warning option for this - only an attribute that has to be
2537 put on the function's prototype. It seems that in Fedora Core 4 they have
2538 set this on a number of new functions. No doubt there will be more in due
2539 course.

PH
2541PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
2542 specify a transport. However, if an address that was verified by such a
2543 router was the subject of a callout, Exim crashed because it tried to
2544 read the rcpt_include_affixes from the non-existent transport. Now it
2545 just assumes that the setting of that option is false. This bug was
2546 introduced by 4.51/PH/31.

PH
2556PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
2557 aren't the modern standard, and it seems that some systems' include files
2558 don't always have them. Exim was already checking for some of the newer
2559 ones like T_AAAA, and defining it itself. I've added checks for all the
2560 record types that Exim uses.

182ad5cf
PH
2562PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
2563 not automatically generating a new one, as it is supposed to. This
2564 prevented TLS from working. If the file did exist, but contained invalid
2565 data, a new version was generated, as expected. It was only the case of a
2566 non-existent file that was broken.

2577PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
2578 the use of a port name that isn't defined in /etc/services) occurred, the
2579 message was deferred as in a normal delivery, and thus remained on the
2580 spool, instead of being failed because of the mua_wrapper setting. This
2581 is now fixed, and I tidied up some of the mua_wrapper messages at the
2582 same time.

SC
2584SC/08 Eximstats: whilst parsing the mainlog(s), store information about

2612 to test Sieve filters that use "vacation".
2613
2614PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2615 that changes the way the GnuTLS parameters are stored in the cache file.
2616 The new format can be generated externally. For backward compatibility,
2617 if the data in the cache doesn't make sense, Exim assumes it has read an
2618 old-format file, and it generates new data and writes a new file. This
2619 means that you can't go back to an older release without removing the
2620 file.
2621
2622PH/03 A redirect router that has both "unseen" and "one_time" set does not
2623 work if there are any delivery delays because "one_time" forces the
2624 parent to be marked "delivered", so its unseen clone is never tried
2625 again. For this reason, Exim now forbids the simultaneous setting of
2626 these two options.
2627
2628PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2629 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2630 entry if you want to know the details. The fix, however, neglected to
2631 consider the case when local delivery batching is involved. The test for
2632 "previously delivered" was not happening when checking to see if an
2633 address could be batched with a previous (undelivered) one; under
2634 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2635 address.
1a46a8c5
PH
2636
2637PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
2638 in its include files, and this causes problems building Exim.
2639
2640PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2641 header_syntax) but Exim was just ignoring anything given after a slash.
2642 In particular, this caused confusion with an attempt to use "verify =
2643 reverse_host_lookup/defer_ok". An error is now given when options are
2644 supplied for verify items that do not have them. (Maybe reverse_host_
2645 lookup should have a defer_ok option, but that's a different point.)
2646
2647PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
2648 defined by RFC 821) to 2048, because there were problems with some AUTH
2649 commands, and RFC 1869 says the size should be increased for extended
2650 SMTP commands that take arguments.

2697PH/19 When an Exim process that is running as root has to create an Exim log
2698 file, it does so in a subprocess that runs as exim:exim so as to get the
2699 ownership right at creation (otherwise, other Exim processes might see
2700 the file with the wrong ownership). There was no test for failure of this
2701 fork() call, which would lead to the process getting stuck as it waited
2702 for a non-existent subprocess. Forks do occasionally fail when resources
2703 run out. I reviewed all the other calls to fork(); they all seem to check
2704 for failure.

PH
2706PH/20 When checking for unexpected SMTP input at connect time (before writing
2707 the banner), Exim was not dealing correctly with a non-positive return
2708 from the read() function. If the client had disconnected by this time,
2709 the result was a log entry for a synchronization error with an empty
2710 string after "input=" when read() returned zero. If read() returned -1
2711 (an event I could not check), uninitialized data bytes were printed.

c5ddb310
PH
2723PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2724 hadn't been configured. The fix is from Juergen Kreileder, who
2725 understands it better than I do:
2726
2727 "Here's what I see happening with three configured cyrus_sasl
2728 authenticators configured (plain, login, cram-md5):
2729
2730 On startup auth_cyrus_sasl_init() gets called for each of these.
2731 This means three calls to sasl_listmech() without a specified mech_list.
2732 => SASL tests which mechs of all available mechs actually work
2733 => three warnings about OTP not working
2734 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2735
2736 With the patch, sasl_listmech() also gets called three times. But now
2737 SASL's mech_list option is set to the server_mech specified in the the
2738 authenticator. Or in other words, the answer from sasl_listmech()
2739 gets limited to just the mech you're testing for (which is different
2740 for each call.)
2741 => the return list contains just 'plain' or 'login', 'cram-md5' or
2742 nothing depending on the value of ob->server_mech.
2743
2744 I've just tested the patch: Authentication still works fine,
2745 unavailable mechs specified in the exim configuration are still
2746 caught, and the auth.log warnings about OTP are gone."

2786 address.

2791 does for delivery: the affixes are removed from the local part unless

PH
2810PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2811 the grounds that routing the same address twice would always produce the
2812 same answer. This might have been true once, but it is certainly no
2813 longer true now. Routing a child address may depend on the previous
2814 routing that produced that child. Some complicated redirection strategies
2815 went wrong when messages had multiple recipients, and made Exim's
2816 behaviour dependent on the order in which the addresses were given.
2817
2818 I have moved the duplicate checking until after the routing is complete.
2819 Exim scans the addresses that are assigned to local and remote
2820 transports, and removes any duplicates. This means that more work will be
2821 done, as duplicates will always all be routed, but duplicates are
2822 presumably rare, so I don't expect this is of any significance.
2823
2824 For deliveries to pipes, files, and autoreplies, the duplicate checking
2825 still happens during the routing process, since they are not going to be
2826 routed further.

2831 connection it has accepted, or it never writes response data. The exiscan
2832 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
2833 blindly assumes that writes won't block so it may never time out."

2870 successful delivery. Such timeouts include transport filter timeouts. For
2871 consistency with the overall process timeout, these timeouts are now
2872 treated as errors, giving rise to delivery failures by default. However,
2873 there is now a new Boolean option for the pipe transport called
2874 timeout_defer, which, if set TRUE, converts the failures into defers for
2875 both kinds of timeout. A transport filter timeout is now identified in

2885A note about Exim versions 4.44 and 4.50
2886----------------------------------------
2887
2888Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2889changes of various kinds. As a consequence, a big documentation update was
2890needed. This delayed the release for rather longer than seemed good, especially
2891in the light of a couple of (minor) security issues. Therefore, the changes
2892that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2893release. So 4.44 and 4.50 are in effect two different branches that both start
2894from 4.43.
2895
2896I have left the 4.50 change log unchanged; it contains all the changes since
28974.43. The change log for 4.44 is below; many of its items are identical to
2898those for 4.50. This seems to be the most sensible way to preserve the
2899historical information.

2917 5. There are several places where Exim runs a non-Exim command in a
2918 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2919 was being done only for the command run by the queryprogram router. It is
2920 now done for all such subprocesses. The other cases are: ${run, transport
2921 filters, and the commands run by the lmtp and pipe transports.

2923 6. Added CONFIGURE_GROUP build-time option.

2925 7. Some older OS have a limit of 256 on the maximum number of file
2926 descriptors. Exim was using setrlimit() to set 1000 as a large value
2927 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2928 systems. I've change it so that if it can't get 1000, it tries for 256.

2933 "control" were broken. There should now be diagnostics for all cases when a
2934 control that does not make sense is encountered.

297522. $host_address is now set to the target address during the checking of
2976 ignore_target_hosts.
2977
297823. When checking ignore_target_hosts for an ipliteral router, no host name was
2979 being passed; this would have caused $sender_host_name to have been used if
2980 matching the list had actually called for a host name (not very likely,
2981 since this list is usually IP addresses). A host name is now passed as
2982 "[x.x.x.x]".
2983
7d468ab8
PH
298424. Changed the calls that set up the SIGCHLD handler in the daemon to use the
2985 code that specifies a non-restarting handler (typically sigaction() in
2986 modern systems) in an attempt to fix a rare and obscure crash bug.
2987
298825. Narrowed the window for a race in the daemon that could cause it to ignore
2989 SIGCHLD signals. This is not a major problem, because they are used only to
2990 wake it up if nothing else does.
2991
62c0818f
PH
299226. A malformed maildirsize file could cause Exim to calculate negative values
2993 for the mailbox size or file count. Odd effects could occur as a result.
2994 The maildirsize information is now recalculated if the size or filecount
2995 end up negative.
2996
26034054
PH

300028. Installed the latest version of exipick from John Jetmore.
3001
90af77f4
PH
300229. In an address list, if the pattern was not a regular expression, an empty
3003 subject address (from a bounce message) matched only if the pattern was an
3004 empty string. Non-empty patterns were not even tested. This was the wrong
3005 because it is perfectly reasonable to use an empty address as part of a
3006 database query. An empty address is now tested by patterns that are
3007 lookups. However, all the other forms of pattern expect the subject to
3008 contain a local part and a domain, and therefore, for them, an empty
3009 address still always fails if the pattern is not itself empty.
3010
d8ef3577
PH
301130. Exim went into a mad DNS loop when attempting to do a callout where the
3012 host was specified on an smtp transport, and looking it up yielded more
3013 than one IP address.
3014
5cb8cbc6
PH
301531. Re-factored the code for checking spool and log partition space into a
3016 function that finds that data and another that does the check. The former
3017 is then used to implement four new variables: $spool_space, $log_space,
3018 $spool_inodes, and $log_inodes.
3019
14702f5b
PH
302032. The RFC2047 encoding function was originally intended for short strings
3021 such as real names; it was not keeping to the 75-character limit for
3022 encoded words that the RFC imposes. It now respects the limit, and
3023 generates multiple encoded words if necessary. To be on the safe side, I
3024 have increased the buffer size for the ${rfc2047: expansion operator from
3025 1024 to 2048 bytes.
3026
063b1e99
PH
302733. It is now permitted to omit both strings after an "if" condition; if the
3028 condition is true, the result is "true". As before, when the second string
3029 is omitted, a false condition yields an empty string. This makes it less
3030 cumbersome to write custom ACL and router conditions.
3031
652e1b65
PH
303234. Failure to deliver a bounce message always caused it to be frozen, even if
3033 there was an errors_to setting on the router. The errors_to setting is now
3034 respected.
3035
6f0c9a4f
PH
303635. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3037 canonical form (fully expanded) before being placed in
3038 $sender_host_address.
3039
33397d19
PH
304036. The table in the code that translates DNS record types into text (T_A to
3041 "A" for instance) was missing entries for NS and CNAME. It is just possible
3042 that this could have caused confusion if both these types were looked up
3043 for the same domain, because the text type is used as part of Exim's
3044 per-process caching. But the chance of anyone hitting this buglet seems
3045 very small.
3046
7bb56e1f
PH
304737. The dnsdb lookup has been extended in a number of ways.
3048
3049 (1) There is a new type, "zns", which walks up the domain tree until it
3050 finds some nameserver records. It should be used with care.
3051
ea3bc19b
PH
3052 (2) There is a new type, "mxh", which is like "mx" except that it returns
3053 just the host names, not the priorities.
3054
3055 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19

3056 looked up. The behaviour when one of the lookups defers can be
3057 controlled by a keyword.
7bb56e1f 3058
ea3bc19b 3059 (4) It is now possible to specify the separator character for use when
7bb56e1f 3060 multiple records are returned.

3064 domain.

307141. Include certificate and key file names in error message when GnuTLS fails

3083 < 0 before doing a fflush(). This bug looks as though it goes back to the
3084 introduction of TLS in release 3.20, but "sometimes" must have been rare

PH
310952. Exim crashed if a remote delivery caused a very long error message to be
3110 recorded - for instance if somebody sent an entire SpamAssassin report back
3111 as a large number of 550 error lines. This bug was coincidentally fixed by
3112 increasing the size of one of Exim's internal buffers (big_buffer) that
3113 happened as part of the Exiscan merge. However, to be on the safe side, I
3114 have made the code more robust (and fixed the comments that describe what
3115 is going on).

PH
312254. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3123 patch that reportedly fixes this has been added. I am not expert enough to
3124 create a test for it. This is what the patch creator wrote:
3125
3126 "I found a little strange behaviour of ldap code when working with
3127 Windows 2003 AD Domain, where users was placed in more than one
3128 Organization Units. When I tried to give exim partial DN, the exit code
3129 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3130 But simultaneously result of request was absolutely normal ldap result,
3131 so I produce this patch..."
3132
3295e65b
PH
3133 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3134 REFERENCE, so I have modified the code to exclude the patch when that macro
3135 is not defined.

3138 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3139 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3140 leaves it alone. Component reversal etc. now happens only for IP addresses.

315159. Two changes related to the smtp_active_hostname option:
3152

3154 (2) The default for smtp_banner uses $smtp_active_hostname instead
3155 of $primary_hostname.

b975ba52
PH
315760. The host_aton() function is supposed to be passed a string that is known
3158 to be a valid IP address. However, in the case of IPv6 addresses, it was
3159 not checking this. This is a hostage to fortune. Exim now panics and dies
3160 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3161 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3162 components; fortuitously, this particular loophole had already been fixed
3163 by change 4.50/55 above.
3164
3165 If there are any other similar loopholes, the new check in host_aton()
3166 itself should stop them being exploited. The report I received stated that
3167 data on the command line could provoke the exploit when Exim was running as
3168 exim, but did not say which command line option was involved. All I could
3169 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3170 running as the user.

317361. There was a buffer overflow vulnerability in the SPA authentication code
3174 (which came originally from the Samba project). I have added a test to the
3175 spa_base64_to_bits() function which I hope fixes it.

PH
317862. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
3179 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
3180

PH
318163. The daemon start-up calls getloadavg() while still root for those OS that
3182 need the first call to be done as root, but it missed one case: when
3183 deliver_queue_load_max is set with deliver_drop_privilege. This is
3184 necessary for the benefit of the queue runner, because there is no re-exec
3185 when deliver_drop_privilege is set.
3186

PH
318764. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3188 This has been fixed.
3189
60dc5e56
PH
319065. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3191 was in use, was not putting the data itself into the right store pool;
3192 consequently, it could be overwritten for a subsequent message in the same
3193 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3194 the caching.)
3195
533244af
PH
319666. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3197
a5a28604
PH
319867. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3199 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3200 the function were treating the return as a boolean value, which happened to
3201 work because 0=false and not-0=true, but is not correct code.
3202
7e634d24
PH
320368. The host_aton() function was not handling scoped IPv6 addresses (those
3204 with, for example, "%eth0" on the end) correctly.
3205
3e11c26b
PH
320669. Fixed some compiler warnings in acl.c for the bitmaps specified with
3207 negated items (that is, ~something) in unsigned ints. Some compilers
3208 apparently mutter when there is no cast.
3209
6729cf78
PH
321070. If an address verification called from an ACL failed, and did not produce a
3211 user-specific message (i.e. there was only a "system" message), nothing was
3212 put in $acl_verify_message. In this situation, it now puts the system
3213 message there.
3214
00f00ca5
PH
321571. Change 4.23/11 added synchronization checking at the start of an SMTP
3216 session; change 4.31/43 added the unwanted input to the log line - except
3217 that it did not do this in the start of session case. It now does.
3218
c9bdd01c
PH
321972. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3220 This is wrong and can cause the other end to generate a synchronization
3221 error if it is another Exim or anything else that does the synchronization
3222 check. A QUIT command is no longer sent after a timeout.
3223
d43194df
PH
322473. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3225 during host lookups.
3226
fe5b5d0b
PH
322774. The defer_ok option of callout verification was not working if it was used
3228 when verifying addresses in header lines, that is, for this case:
3229
3230 verify = header_sender/callout=defer_ok
3231
76a2d7ba
PH
323275. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3233 those file descriptors could be used for SMTP connections. If anything
3234 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3235 could be sent to the SMTP client, causing chaos. The daemon now opens
3236 stdin, stdout, and stderr to /dev/null when it puts itself into the
3237 background.
3238
323976. Arrange for output from Perl's "warn" command to be written to Exim's main
3240 log by default. The user can override this with suitable Perl magic.
3241
04f7d5b9
PH
324277. The use of log_message on a "discard" ACL verb, which is supposed to add to
3243 the log message when discard triggers, was not working for the DATA ACL or
3244 for the non-SMTP ACL.
3245
bc60667e
PH
324678. Error message wording change in sieve.c.
3247
bb6e88ff
PH
324879. If smtp_accept_max_per_host was set, the number of connections could be
3249 restricted to fewer than expected, because the daemon was trying to set up
3250 a new connection before checking whether the processes handling previous
3251 connections had finished. The check for completed processes is now done
3252 earlier. On busy systems, this bug wouldn't be noticed because something
3253 else would have woken the daemon, and it would have reaped the completed
3254 process earlier.
3255
1e70f85b
PH
325680. If a message was submitted locally by a user whose login name contained one
3257 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3258 It caused a spool format error. I have fixed the spool reading code. A
3259 related problem was that the "from" clause in the Received: line became
3260 illegal because of the space(s). It is now covered by ${quote_local_part.
3261
326281. Included the latest eximstats from Steve (adds average sizes to HTML Top
3263 tables).

3276----------------------------------------------------
3277See the note above about the 4.44 and 4.50 releases.
3278----------------------------------------------------
3279
3280
3281Exim version 4.44
3282-----------------
3283
3284 1. Change 4.43/35 introduced a bug that caused file counts to be
3285 incorrectly computed when quota_filecount was set in an appendfile
3286 transport
3287
3288 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3289 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3290 place.
3291
3292 3. Give more explanation in the error message when the command for a transport
3293 filter fails to execute.
3294
3295 4. There are several places where Exim runs a non-Exim command in a
3296 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3297 was being done only for the command run by the queryprogram router. It is
3298 now done for all such subprocesses. The other cases are: ${run, transport
3299 filters, and the commands run by the lmtp and pipe transports.
3300
3301 5. Some older OS have a limit of 256 on the maximum number of file
3302 descriptors. Exim was using setrlimit() to set 1000 as a large value
3303 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3304 systems. I've change it so that if it can't get 1000, it tries for 256.
3305
3306 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3307 was an oversight, and furthermore, ever since the addition of extra
3308 controls (e.g. 4.43/32), the checks on when to allow different forms of
3309 "control" were broken. There should now be diagnostics for all cases when a
3310 control that does not make sense is encountered.
3311
3312 7. $recipients is now available in the predata ACL (oversight).
3313
3314 8. Tidy the search cache before the fork to do a delivery from a message
3315 received from the command line. Otherwise the child will trigger a lookup
3316 failure and thereby defer the delivery if it tries to use (for example) a
3317 cached ldap connection that the parent has called unbind on.
3318
3319 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3320 of $address_data from the recipient verification was clobbered by the
3321 sender verification.
3322
332310. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3324 was its contents. (It was OK if the option was not defined at all.)
3325
332611. A "Completed" log line is now written for messages that are removed from
3327 the spool by the -Mrm option.
3328
332912. $host_address is now set to the target address during the checking of
3330 ignore_target_hosts.
3331
333213. When checking ignore_target_hosts for an ipliteral router, no host name was
3333 being passed; this would have caused $sender_host_name to have been used if
3334 matching the list had actually called for a host name (not very likely,
3335 since this list is usually IP addresses). A host name is now passed as
3336 "[x.x.x.x]".
3337
333814. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3339 code that specifies a non-restarting handler (typically sigaction() in
3340 modern systems) in an attempt to fix a rare and obscure crash bug.
3341
334215. Narrowed the window for a race in the daemon that could cause it to ignore
3343 SIGCHLD signals. This is not a major problem, because they are used only to
3344 wake it up if nothing else does.
3345
334616. A malformed maildirsize file could cause Exim to calculate negative values
3347 for the mailbox size or file count. Odd effects could occur as a result.
3348 The maildirsize information is now recalculated if the size or filecount
3349 end up negative.
3350
335117. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3352 support for a long time. Removed HAVE_SYS_VFS_H.
3353
ea3a6f44 335418. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3355
335619. Allow an empty sender to be matched against a lookup in an address list.
3357 Previously the only cases considered were a regular expression, or an
3358 empty pattern.
3359
336020. Exim went into a mad DNS lookup loop when doing a callout where the
3361 host was specified on the transport, if the DNS lookup yielded more than
3362 one IP address.
3363
ea3a6f44
NM
336421. The RFC2047 encoding function was originally intended for short strings
3365 such as real names; it was not keeping to the 75-character limit for
3366 encoded words that the RFC imposes. It now respects the limit, and
3367 generates multiple encoded words if necessary. To be on the safe side, I
3368 have increased the buffer size for the ${rfc2047: expansion operator from
3369 1024 to 2048 bytes.
bbe902f0 3370
ea3a6f44
NM
337122. Failure to deliver a bounce message always caused it to be frozen, even if
3372 there was an errors_to setting on the router. The errors_to setting is now
3373 respected.
bbe902f0
PH
3374
337523. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3376 canonical form (fully expanded) before being placed in
3377 $sender_host_address.
3378
337924. Updated eximstats to version 1.33
3380
ea3a6f44
NM
338125. Include certificate and key file names in error message when GnuTLS fails
3382 to set them up, because the GnuTLS error message doesn't include the name
3383 of the failing file when there is a problem reading it.
bbe902f0
PH
3384
338526. Expand error message when OpenSSL has problems setting up cert/key files.
ea3a6f44 3386 As per change 25.
bbe902f0 3387
ea3a6f44
NM
338827. Reset the locale to "C" after calling embedded Perl, in case it was changed
3389 (this can affect the format of dates).
bbe902f0 3390
ea3a6f44
NM
339128. exim_tidydb, when checking for the continued existence of a message for
3392 which it has found a message-specific retry record, was not finding
3393 messages that were in split spool directories. Consequently, it was
3394 deleting retry records that should have stayed in existence.
bbe902f0
PH
3395
339629. eximstats updated to version 1.35
3397 1.34 - allow eximstats to parse syslog lines as well as mainlog lines
3398 1.35 - bugfix such that pie charts by volume are generated correctly
3399
ea3a6f44
NM
340030. The SPA authentication driver was not abandoning authentication and moving
3401 on to the next authenticator when an expansion was forced to fail,
3402 contradicting the general specification for all authenticators. Instead it
3403 was generating a temporary error. It now behaves as specified.
bbe902f0 3404
ea3a6f44
NM
340531. The default ordering of permitted cipher suites for GnuTLS was pessimal
3406 (the order specifies the preference for clients). The order is now AES256,
3407 AES128, 3DES, ARCFOUR128.
bbe902f0 3408
ea3a6f44
NM
340931. Small patch to Sieve code - explicitly set From: when generating an
3410 autoreply.
bbe902f0 3411
ea3a6f44

341232. Exim crashed if a remote delivery caused a very long error message to be
