TF
67TF/03 Make the exiwhat support code safe for signals. Previously Exim might
68 lock up or crash if it happened to be inside a call to libc when it
69 got a SIGUSR1 from exiwhat.
70
71 The SIGUSR1 handler appends the current process status to the process
72 log which is later printed by exiwhat. It used to use the general
73 purpose logging code to do this, but several functions it calls are
74 not safe for signals.
75
76 The new output code in the SIGUSR1 handler is specific to the process
77 log, and simple enough that it's easy to inspect for signal safety.
78 Removing some special cases also simplifies the general logging code.
79 Removing the spurious timestamps from the process log simplifies
80 exiwhat.
81
c99ce5c9
TF
82TF/04 Improved ratelimit ACL condition.
83
84 The /noupdate option has been deprecated in favour of /readonly which
85 has clearer semantics. The /leaky, /strict, and /readonly update modes
86 are mutually exclusive. The update mode is no longer included in the
87 database key; it just determines when the database is updated. (This
88 means that when you upgrde Exim will forget old rate measurements.)
89
90 Exim now checks that the per_* options are used with an update mode that
91 makes sense for the current ACL. For example, when Exim is processing a
92 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
93 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
94 must specify per_mail/readonly. If you omit the update mode it defaults to
95 /leaky where that makes sense (as before) or /readonly where required.
96
97 The /noupdate option is now undocumented but still supported for
98 backwards compatibility. It is equivalent to /readonly except that in
99 ACLs where /readonly is required you may specify /leaky/noupdate or
100 /strict/noupdate which are treated the same as /readonly.
101
102 A useful new feature is the /count= option. This is a generalization
103 of the per_byte option, so that you can measure the throughput of other
104 aggregate values. For example, the per_byte option is now equivalent
105 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
106
107 The per_rcpt option has been generalized using the /count= mechanism
108 (though it's more complicated than the per_byte equivalence). When it is
109 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
110 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
111 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
112 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
113 Note that using per_rcpt with a non-readonly update mode in more than
114 one ACL will cause the recipients to be double-counted. (The per_mail
115 and per_byte options don't have this problem.)
116
117 The handling of very low rates has changed slightly. If the computed rate
118 is less than the event's count (usually one) then this event is the first
119 after a long gap. In this case the rate is set to the same as this event's
120 count, so that the first message of a spam run is counted properly.
121
122 The major new feature is a mechanism for counting the rate of unique
123 events. The new per_addr option counts the number of different
124 recipients that someone has sent messages to in the last time period. It
125 behaves like per_rcpt if all the recipient addresses are different, but
126 duplicate recipient addresses do not increase the measured rate. Like
127 the /count= option this is a general mechanism, so the per_addr option
128 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
129 example, measure the rate that a client uses different sender addresses
130 with the options per_mail/unique=$sender_address. There are further
131 details in the main documentation.

703PH/01 Another patch from the Sieve maintainer.
704
6a3bceb1
PH
705PH/02 When an IPv6 address is converted to a string for single-key lookup
706 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
707 dots are used instead of colons so that keys in lsearch files need not
708 contain colons. This was done some time before quoting was made available
709 in lsearch files. However, iplsearch files do require colons in IPv6 keys
710 (notated using the quote facility) so as to distinguish them from IPv4
711 keys. This meant that lookups for IP addresses in host lists did not work
712 for iplsearch lookups.
713
714 This has been fixed by arranging for IPv6 addresses to be expressed with
715 colons if the lookup type is iplsearch. This is not incompatible, because
716 previously such lookups could never work.
717
718 The situation is now rather anomolous, since one *can* have colons in
719 ordinary lsearch keys. However, making the change in all cases is
720 incompatible and would probably break a number of configurations.

725MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
726 conversion specification without a maximum field width, thereby enabling
727 a rogue spamd server to cause a buffer overflow. While nobody in their
728 right mind would setup Exim to query an untrusted spamd server, an
729 attacker that gains access to a server running spamd could potentially
730 exploit this vulnerability to run arbitrary code as the Exim user.

MH
735MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
736 a directory entry by the name of the lookup key. Previously, if a
737 symlink pointed to a non-existing file or a file in a directory that
738 Exim lacked permissions to read, a lookup for a key matching that
739 symlink would fail. Now it is enough that a matching directory entry
740 exists, symlink or not. (Bugzilla 503.)

813PH/02 In an ACL statement such as

817 if a client was not listed at all, or was listed with a value other than
818 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
819 the condition was not true (as it should be), so access was not denied.
820 The bug was that the ! inversion was incorrectly passed on to the second

PH
923PH/29 SMTP synchronization checks are implemented when a command is read -
924 there is a check that no more input is waiting when there shouldn't be
925 any. However, for some commands, a delay in an ACL can mean that it is
926 some time before the response is written. In this time, more input might
927 arrive, invalidly. So now there are extra checks after an ACL has run for
928 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
929 pipelining has not been advertised.

941PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
942 Exim which did not show up earlier: it was assuming that a call to
943 SSL_CTX_set_info_callback() might give an error value. In fact, there is
944 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
945 was a macro that became an assignment, so it seemed to work. This has
946 changed to a proper function call with a void return, hence the compile
947 error. Exim's code has been fixed.

PH
975PH/40 When Exim receives a message, it writes the login name, uid, and gid of
976 whoever called Exim into the -H file. In the case of the daemon it was
977 behaving confusingly. When first started, it used values for whoever
978 started the daemon, but after a SIGHUP it used the Exim user (because it
979 calls itself on a restart). I have changed the code so that it now always
980 uses the Exim user.

982PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a

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

58eb016e 1002PH/44 I found a way to check for a TCP/IP connection going away before sending

PH
1003 the response to the final '.' that terminates a message, but only in the
1004 case where the client has not sent further data following the '.'
1005 (unfortunately, this is allowed). However, in many cases there won't be
1006 any further data because there won't be any more messages to send. A call
1007 to select() can be used: if it shows that the input is "ready", there is
1008 either input waiting, or the socket has been closed. An attempt to read
1009 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1010 would have sent an OK response which the client would never have see.

1020
1021PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1022 fixed by 4.65/MH/01 (is this a record?) are fixed:
1023
1024 (i) An empty string was always treated as zero by the numeric comparison
1025 operators. This behaviour has been restored.
1026
1027 (ii) It is documented that the numeric comparison operators always treat
1028 their arguments as decimal numbers. This was broken in that numbers
1029 starting with 0 were being interpreted as octal.
1030
1031 While fixing these problems I realized that there was another issue that
1032 hadn't been noticed. Values of message_size_limit (both the global option
1033 and the transport option) were treated as octal if they started with 0.
1034 The documentation was vague. These values are now always treated as
1035 decimal, and I will make that clear in the documentation.

1049PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1050 child addresses, Exim now panics and dies. Previously, because the count
1051 is held in a short int, deliveries were likely to be lost. As such a
1052 large number of recipients for a single message is ridiculous
1053 (performance will be very, very poor), I have chosen to impose a limit
1054 rather than extend the field.

1060TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1061 leftover -K file (the existence of which was triggered by #402).

1069
1070TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

2b1c6e3a
PH
1079PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1080 callout verification, Exim cached a "reject" for the entire domain. This
1081 is correct for most verifications, but it is not correct for a recipient
1082 verification with use_sender or use_postmaster set, because in that case
1083 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1084 case of MAIL FROM:<> rejection from other early rejections (e.g.
1085 rejection of HELO). When verifying a recipient using a non-null MAIL
1086 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1087 Whatever the result of the callout, the value of the domain cache is
1088 left unchanged (for any other kind of callout, getting as far as trying
1089 RCPT means that the domain itself is ok).

1123PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1124 hostname. This is wrong, because it relates to the incoming message (and
1125 probably the interface on which it is arriving) and not to the outgoing
1126 callout (which could be using a different interface). This has been
1127 changed to use the value of the helo_data option from the smtp transport
1128 instead - this is what is used when a message is actually being sent. If
1129 there is no remote transport (possible with a router that sets up host
1130 addresses), $smtp_active_hostname is used.

14aa5a05 1132PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1133 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1134 (a) The code assumed that strncpy() returns a negative number on buffer
1135 overflow, which isn't the case. Replaced with Exim's string_format()
1136 function.
1137 (b) There were several signed/unsigned issues. I just did the minimum
1138 hacking in of casts. There is scope for a larger refactoring.
1139 (c) The code used strcasecmp() which is not a standard C function.
1140 Replaced with Exim's strcmpic() function.
1141 (d) The code set only $1; it now sets $auth1 as well.
1142 (e) A simple test gave the error "authentication client didn't specify
1143 service in request". It would seem that Dovecot has changed its
1144 interface. Fortunately there's a specification; I followed it and
1145 changed what the client sends and it appears to be working now.

1150PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1151 address A is aliased to B and C, where B exists and C does not. Without
1152 -v the output is "A verified" because verification stops after a
1153 successful redirection if more than one address is generated. However,
1154 with -v the child addresses are also verified. Exim was outputting "A
1155 failed to verify" and then showing the successful verification for C,
1156 with its parentage. It now outputs "B failed to verify", showing B's
1157 parentage before showing the successful verification of C.

1160 look up a TXT record in a specific list after matching in a combined

1162
322050c2
PH
1163PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1164 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1165 they consult the DNS. I had assumed they would set it the way they
1166 wanted; and indeed my experiments on Linux seem to show that in some
1167 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1168 To be on the safe side, however, I have now made the interface to
1169 host_find_byname() similar to host_find_bydns(), with an argument
1170 containing the DNS resolver options. The host_find_byname() function now
1171 sets these options at its start, just as host_find_bydns() does. The smtp
1172 transport options dns_qualify_single and dns_search_parents are passed to
1173 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1174 of host_find_byname() use the default settings of RES_DEFNAMES
1175 (qualify_single) but not RES_DNSRCH (search_parents).

1177PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1178 spool_read_header() do less string testing, by means of a preliminary
1179 switch on the second character of optional "-foo" lines. (This is
1180 overdue, caused by the large number of possibilities that now exist.
1181 Originally there were few.) While I was there, I also converted the
1182 str(n)cmp tests so they don't re-test the leading "-" and the first
1183 character, in the hope this might squeeze out yet more improvement.

1185PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1186 flag allowing group syntax was set by the header_syntax check but not
1187 turned off, possible causing trouble later; (2) The flag was not being
1188 set at all for the header_verify test, causing "group"-style headers to
1189 be rejected. I have now set it in this case, and also caused header_
1190 verify to ignore an empty address taken from a group. While doing this, I
1191 came across some other cases where the code for allowing group syntax
1192 while scanning a header line wasn't quite right (mostly, not resetting
1193 the flag correctly in the right place). These bugs could have caused
1194 trouble for malformed header lines. I hope it is now all correct.

1197 with the "reply" argument non-NULL. The code, however (which originally
1198 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1199 but it didn't always do it. This confused somebody who was copying the
1200 code for some other use. I have removed all the tests.

1202PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1203 feature that was used to support insecure browsers during the U.S. crypto
1204 embargo. It requires special client support, and Exim is probably the
1205 only MTA that supported it -- and would never use it because real RSA is
1206 always available. This code has been removed, because it had the bad
1207 effect of slowing Exim down by computing (never used) parameters for the
1208 RSA_EXPORT functionality.

1210PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1211 authenticator to fail if there's a tab character in the incoming data
1212 (there should never be unless someone is messing about, as it's supposed
1213 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1214 if the connection is using TLS or if the remote IP is the same as the
1215 local IP, and the "valid-client-cert option" if a client certificate has
1216 been verified.

1247
1248PH/30 Exim was sometimes attempting to deliver messages that had suffered
1249 address errors (4xx response to RCPT) over the same connection as other
1250 messages routed to the same hosts. Such deliveries are always "forced",
1251 so retry times are not inspected. This resulted in far too many retries
1252 for the affected addresses. The effect occurred only when there were more
1253 hosts than the hosts_max_try setting in the smtp transport when it had
1254 the 4xx errors. Those hosts that it had tried were not added to the list
1255 of hosts for which the message was waiting, so if all were tried, there
1256 was no problem. Two fixes have been applied:
1257
1258 (i) If there are any address or message errors in an SMTP delivery, none
1259 of the hosts (tried or untried) are now added to the list of hosts
1260 for which the message is waiting, so the message should not be a
1261 candidate for sending over the same connection that was used for a
1262 successful delivery of some other message. This seems entirely
1263 reasonable: after all the message is NOT "waiting for some host".
1264 This is so "obvious" that I'm not sure why it wasn't done
1265 previously. Hope I haven't missed anything, but it can't do any
1266 harm, as the worst effect is to miss an optimization.
1267
1268 (ii) If, despite (i), such a delivery is accidentally attempted, the
1269 routing retry time is respected, so at least it doesn't keep
1270 hammering the server.

1285PH/35 The error "getsockname() failed: connection reset by peer" was being
1286 written to the panic log as well as the main log, but it isn't really
1287 panic-worthy as it just means the connection died rather early on. I have
1288 removed the panic log writing for the ECONNRESET error when getsockname()
1289 fails.
1290
48c7f9e2
PH
1291PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1292 runs only) independently of the message's sender address. This meant
1293 that, if the 4xx error was in fact related to the sender, a different
1294 message to the same recipient with a different sender could confuse
1295 things. In particualar, this can happen when sending to a greylisting
1296 server, but other circumstances could also provoke similar problems.
1297 I have changed the default so that the retry time for these errors is now
1298 based a combination of the sender and recipient addresses. This change
1299 can be overridden by setting address_retry_include_sender=false in the
1300 smtp transport.

1574 554 error is used if errno is still zero or contains ENOENT (which occurs

1598PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
1599 folder from quota calculations, a direct delivery into this folder messed
1600 up the contents of the maildirsize file. This was because the regex was
1601 used only to exclude .Trash (or whatever) when the size of the mailbox
1602 was calculated. There was no check that a delivery was happening into an
1603 excluded directory. This bug has been fixed by ignoring all quota

1612PH/01 The code for finding all the local interface addresses on a FreeBSD
1613 system running IPv6 was broken. This may well have applied to all BSD
1614 systems, as well as to others that have similar system calls. The broken
1615 code found IPv4 interfaces correctly, but gave incorrect values for the
1616 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1617 that it would not match correctly against @[] and not recognize the IPv6
1618 addresses as local.

1697 Instead, it always explicitly searches for A/AAAA records. This avoids
1698 major problems that occur when a DNS server includes only records of one
1699 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1700 fixed another bug: if SRV records were looked up and the corresponding
1701 address records were *not* found in the additional section, the port
1702 values from the SRV records were lost.

PH
1712PH/19 When calculating a retry time, Exim used to measure the "time since
1713 failure" by looking at the "first failed" field in the retry record. Now
1714 it does not use this if it is later than than the arrival time of the
1715 message. Instead it uses the arrival time. This makes for better
1716 behaviour in cases where some deliveries succeed, thus re-setting the
1717 "first failed" field. An example is a quota failure for a huge message
1718 when small messages continue to be delivered. Without this change, the
1719 "time since failure" will always be short, possible causing more frequent
1720 delivery attempts for the huge message than are intended.

PH
1817PH/42 The content-scanning code uses fopen() to create files in which to put
1818 message data. Previously it was not paying any attention to the mode of
1819 the files. Exim runs with umask(0) because the rest of the code creates
1820 files with open(), and sets the required mode explicitly. Thus, these
1821 files were ending up world-writeable. This was not a big issue, because,
1822 being within the spool directory, they were not world-accessible. I have
1823 created a function called modefopen, which takes an additional mode
1824 argument. It sets umask(777), creates the file, chmods it to the required
1825 mode, then resets the umask. All the relevant calls to fopen() in the
1826 content scanning code have been changed to use this function.

1863
1864 (i) Exim was not creating retry information for temporary errors given

1866 was used in LMTP mode. This meant that they could be retried too
1867 frequently, and not timed out correctly.
1868
1869 (ii) Exim was setting the flag that allows error details to be returned
1870 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1871 recipients that were returned after the DATA command.
1872
1873PH/53 This is related to PH/52, but is more general: for any failing address,
1874 when detailed error information was permitted to be returned to the

1948 function verify_get_ident() calls ip_connect() to connect a socket, but
1949 if the "connect()" function timed out, ip_connect() used to close the
1950 socket. However, verify_get_ident() also closes the socket later, and in
1951 between Exim writes to the log, which may get opened at this point. When
1952 the socket was closed in ip_connect(), the log could get the same file
1953 descriptor number as the socket. This naturally causes chaos. The fix is
1954 not to close the socket in ip_connect(); the socket should be closed by
1955 the function that creates it. There was only one place in the code where
1956 this was missing, in the iplookup router, which I don't think anybody now

1976PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
1977
1978 (1) Generate an error if the third argument for the ${prvs expansion is
1979 not a single digit.
1980
1981 (2) Treat a missing third argument of ${prvscheck as if it were an empty
1982 string.
1983
1984 (3) Reset the variables that are obtained from the first argument of
1985 ${prvscheck and used in the second argument before leaving the code,
1986 because their memory is reclaimed, so using them afterwards may do
1987 silly things.
1988
1989 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
1990 one (it's much easier than Tom thought :-).
1991
1992 (5) Because of (4), we can now allow for the use of $prvscheck_result
1993 inside the third argument.

2014 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2015 not being looked up in the rDNS to get a host name, Exim was showing the
2016 IP address twice in Received: lines, even though the IP addresses were
2017 identical. For example:
2018
2019 Received: from [1.2.3.4] (helo=[1.2.3.4])
2020
2021 However, if the real host name was known, it was omitting the HELO data

2023 doesn't show the same IP address twice.

2056 also a typo: it was using "Auto_submitted" (underscore instead of
2057 hyphen). Since every message generated by Exim is necessarily in response
2058 to another message, thes have all been changed to:
2059
2060 Auto-Submitted: auto-replied
2061
2062 in accordance with these statements in the RFC:
2063
2064 The auto-replied keyword:

2067 message by an automatic process,

2114 the IP address, check_host() was doing a simple string comparison with
2115 addresses acquired from the DNS when checking that the found name did
2116 have the original IP as one of its addresses. Since any found IPv6
2117 addresses are likely to be in abbreviated form, the comparison could
2118 fail. Luckily, there already exists a function for doing the comparison
2119 by converting both addresses to binary, so now that is used instead of
2120 the text comparison.

2417PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2418 with the definition in sysexits.h (which is #included earlier).
2419 Fortunately, Exim does not actually use EX_OK. The code used to try to
2420 preserve the sysexits.h value, by assumimg that macro definitions were
2421 scanned for macro replacements. I have been disabused of this notion,
2422 so now the code just undefines EX_OK before #including unistd.h.

2424PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout

2427 This seems wrong - if the receiver was accepting one byte at a time it
2428 would take for ever. The timeout is now adjusted when this happens. It
2429 doesn't have to be particularly precise.

2638PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2639 that changes the way the GnuTLS parameters are stored in the cache file.
2640 The new format can be generated externally. For backward compatibility,
2641 if the data in the cache doesn't make sense, Exim assumes it has read an
2642 old-format file, and it generates new data and writes a new file. This
2643 means that you can't go back to an older release without removing the
2644 file.
2645
2646PH/03 A redirect router that has both "unseen" and "one_time" set does not
2647 work if there are any delivery delays because "one_time" forces the
2648 parent to be marked "delivered", so its unseen clone is never tried
2649 again. For this reason, Exim now forbids the simultaneous setting of
2650 these two options.
2651
2652PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2653 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2654 entry if you want to know the details. The fix, however, neglected to
2655 consider the case when local delivery batching is involved. The test for
2656 "previously delivered" was not happening when checking to see if an
2657 address could be batched with a previous (undelivered) one; under
2658 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2659 address.

2664PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =

2666 In particular, this caused confusion with an attempt to use "verify =
2667 reverse_host_lookup/defer_ok". An error is now given when options are
2668 supplied for verify items that do not have them. (Maybe reverse_host_
2669 lookup should have a defer_ok option, but that's a different point.)

2724 the file with the wrong ownership). There was no test for failure of this
2725 fork() call, which would lead to the process getting stuck as it waited

2747PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it

2749 understands it better than I do:
2750
2751 "Here's what I see happening with three configured cyrus_sasl
2752 authenticators configured (plain, login, cram-md5):
2753
2754 On startup auth_cyrus_sasl_init() gets called for each of these.
2755 This means three calls to sasl_listmech() without a specified mech_list.
2756 => SASL tests which mechs of all available mechs actually work
2757 => three warnings about OTP not working
2758 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2759
2760 With the patch, sasl_listmech() also gets called three times. But now
2761 SASL's mech_list option is set to the server_mech specified in the the
2762 authenticator. Or in other words, the answer from sasl_listmech()
2763 gets limited to just the mech you're testing for (which is different
2764 for each call.)
2765 => the return list contains just 'plain' or 'login', 'cram-md5' or
2766 nothing depending on the value of ob->server_mech.
2767

2802 . Two addresses routed to the same list of hosts;

2806 . Second host offers TLS and a TLS session is established;

PH
2834PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2835 the grounds that routing the same address twice would always produce the
2836 same answer. This might have been true once, but it is certainly no
2837 longer true now. Routing a child address may depend on the previous
2838 routing that produced that child. Some complicated redirection strategies
2839 went wrong when messages had multiple recipients, and made Exim's
2840 behaviour dependent on the order in which the addresses were given.
2841
2842 I have moved the duplicate checking until after the routing is complete.
2843 Exim scans the addresses that are assigned to local and remote
2844 transports, and removes any duplicates. This means that more work will be
2845 done, as duplicates will always all be routed, but duplicates are
2846 presumably rare, so I don't expect this is of any significance.
2847
2848 For deliveries to pipes, files, and autoreplies, the duplicate checking
2849 still happens during the routing process, since they are not going to be
2850 routed further.

2856 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
2857 blindly assumes that writes won't block so it may never time out."

2883 as "unrouteable address" or "local delivery error" are given.

2894 successful delivery. Such timeouts include transport filter timeouts. For
2895 consistency with the overall process timeout, these timeouts are now
2896 treated as errors, giving rise to delivery failures by default. However,
2897 there is now a new Boolean option for the pipe transport called
2898 timeout_defer, which, if set TRUE, converts the failures into defers for
2899 both kinds of timeout. A transport filter timeout is now identified in

2909A note about Exim versions 4.44 and 4.50
2910----------------------------------------
2911
2912Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2913changes of various kinds. As a consequence, a big documentation update was
2914needed. This delayed the release for rather longer than seemed good, especially
2915in the light of a couple of (minor) security issues. Therefore, the changes
2916that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2917release. So 4.44 and 4.50 are in effect two different branches that both start
2918from 4.43.
2919
2920I have left the 4.50 change log unchanged; it contains all the changes since
29214.43. The change log for 4.44 is below; many of its items are identical to
2922those for 4.50. This seems to be the most sensible way to preserve the
2923historical information.

2941 5. There are several places where Exim runs a non-Exim command in a
2942 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2943 was being done only for the command run by the queryprogram router. It is
2944 now done for all such subprocesses. The other cases are: ${run, transport
2945 filters, and the commands run by the lmtp and pipe transports.

2947 6. Added CONFIGURE_GROUP build-time option.
2948
2949 7. Some older OS have a limit of 256 on the maximum number of file
2950 descriptors. Exim was using setrlimit() to set 1000 as a large value
2951 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2952 systems. I've change it so that if it can't get 1000, it tries for 256.

2954 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
2955 was an oversight, and furthermore, ever since the addition of extra
2956 controls (e.g. 4.43/32), the checks on when to allow different forms of
2957 "control" were broken. There should now be diagnostics for all cases when a
2958 control that does not make sense is encountered.

299922. $host_address is now set to the target address during the checking of
3000 ignore_target_hosts.
3001
300223. When checking ignore_target_hosts for an ipliteral router, no host name was
3003 being passed; this would have caused $sender_host_name to have been used if
3004 matching the list had actually called for a host name (not very likely,
3005 since this list is usually IP addresses). A host name is now passed as
3006 "[x.x.x.x]".
3007
7d468ab8
PH
300824. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3009 code that specifies a non-restarting handler (typically sigaction() in
3010 modern systems) in an attempt to fix a rare and obscure crash bug.
3011
301225. Narrowed the window for a race in the daemon that could cause it to ignore
3013 SIGCHLD signals. This is not a major problem, because they are used only to
3014 wake it up if nothing else does.
3015
62c0818f
PH
301626. A malformed maildirsize file could cause Exim to calculate negative values
3017 for the mailbox size or file count. Odd effects could occur as a result.
3018 The maildirsize information is now recalculated if the size or filecount
3019 end up negative.
3020
26034054
PH
302127. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this

PH
302629. In an address list, if the pattern was not a regular expression, an empty
3027 subject address (from a bounce message) matched only if the pattern was an
3028 empty string. Non-empty patterns were not even tested. This was the wrong
3029 because it is perfectly reasonable to use an empty address as part of a
3030 database query. An empty address is now tested by patterns that are
3031 lookups. However, all the other forms of pattern expect the subject to
3032 contain a local part and a domain, and therefore, for them, an empty
3033 address still always fails if the pattern is not itself empty.
3034
d8ef3577
PH
303530. Exim went into a mad DNS loop when attempting to do a callout where the
3036 host was specified on an smtp transport, and looking it up yielded more
3037 than one IP address.
3038
5cb8cbc6
PH
303931. Re-factored the code for checking spool and log partition space into a
3040 function that finds that data and another that does the check. The former
3041 is then used to implement four new variables: $spool_space, $log_space,
3042 $spool_inodes, and $log_inodes.
3043
14702f5b
PH
304432. The RFC2047 encoding function was originally intended for short strings
3045 such as real names; it was not keeping to the 75-character limit for
3046 encoded words that the RFC imposes. It now respects the limit, and
3047 generates multiple encoded words if necessary. To be on the safe side, I
3048 have increased the buffer size for the ${rfc2047: expansion operator from
3049 1024 to 2048 bytes.
3050
063b1e99
PH
305133. It is now permitted to omit both strings after an "if" condition; if the
3052 condition is true, the result is "true". As before, when the second string
3053 is omitted, a false condition yields an empty string. This makes it less
3054 cumbersome to write custom ACL and router conditions.
3055
652e1b65
PH
305634. Failure to deliver a bounce message always caused it to be frozen, even if
3057 there was an errors_to setting on the router. The errors_to setting is now
3058 respected.
3059
6f0c9a4f
PH
306035. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3061 canonical form (fully expanded) before being placed in
3062 $sender_host_address.
3063
33397d19
PH
306436. The table in the code that translates DNS record types into text (T_A to
3065 "A" for instance) was missing entries for NS and CNAME. It is just possible
3066 that this could have caused confusion if both these types were looked up
3067 for the same domain, because the text type is used as part of Exim's
3068 per-process caching. But the chance of anyone hitting this buglet seems
3069 very small.
3070
7bb56e1f
PH
307137. The dnsdb lookup has been extended in a number of ways.
3072
3073 (1) There is a new type, "zns", which walks up the domain tree until it
3074 finds some nameserver records. It should be used with care.
3075
ea3bc19b
PH
3076 (2) There is a new type, "mxh", which is like "mx" except that it returns

3106 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3107 < 0 before doing a fflush(). This bug looks as though it goes back to the

313352. Exim crashed if a remote delivery caused a very long error message to be
3134 recorded - for instance if somebody sent an entire SpamAssassin report back
3135 as a large number of 550 error lines. This bug was coincidentally fixed by
3136 increasing the size of one of Exim's internal buffers (big_buffer) that
3137 happened as part of the Exiscan merge. However, to be on the safe side, I
3138 have made the code more robust (and fixed the comments that describe what
3139 is going on).

PH
314654. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3147 patch that reportedly fixes this has been added. I am not expert enough to
3148 create a test for it. This is what the patch creator wrote:
3149
3150 "I found a little strange behaviour of ldap code when working with
3151 Windows 2003 AD Domain, where users was placed in more than one
3152 Organization Units. When I tried to give exim partial DN, the exit code
3153 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3154 But simultaneously result of request was absolutely normal ldap result,
3155 so I produce this patch..."
3156
3295e65b
PH
3157 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3158 REFERENCE, so I have modified the code to exclude the patch when that macro
3159 is not defined.

PH
317258. The exicyclog utility now does better if the number of log files to keep
3173 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
3174

PH
317559. Two changes related to the smtp_active_hostname option:
3176
3177 (1) $smtp_active_hostname is now available as a variable.
3178 (2) The default for smtp_banner uses $smtp_active_hostname instead
3179 of $primary_hostname.

PH
318160. The host_aton() function is supposed to be passed a string that is known
3182 to be a valid IP address. However, in the case of IPv6 addresses, it was
3183 not checking this. This is a hostage to fortune. Exim now panics and dies
3184 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3185 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3186 components; fortuitously, this particular loophole had already been fixed
3187 by change 4.50/55 above.
3188
3189 If there are any other similar loopholes, the new check in host_aton()
3190 itself should stop them being exploited. The report I received stated that
3191 data on the command line could provoke the exploit when Exim was running as
3192 exim, but did not say which command line option was involved. All I could
3193 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3194 running as the user.

3196
319761. There was a buffer overflow vulnerability in the SPA authentication code
3198 (which came originally from the Samba project). I have added a test to the
3199 spa_base64_to_bits() function which I hope fixes it.
ea3a6f44 3200 CAN-2005-0022

320262. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
3203 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
3204
d95f9fdb
PH
320563. The daemon start-up calls getloadavg() while still root for those OS that
3206 need the first call to be done as root, but it missed one case: when
3207 deliver_queue_load_max is set with deliver_drop_privilege. This is
3208 necessary for the benefit of the queue runner, because there is no re-exec
3209 when deliver_drop_privilege is set.
3210
86b8287f
PH
321164. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3212 This has been fixed.
3213
60dc5e56
PH
321465. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3215 was in use, was not putting the data itself into the right store pool;
3216 consequently, it could be overwritten for a subsequent message in the same
3217 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3218 the caching.)
3219

PH
322066. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3221
a5a28604
PH
322267. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3223 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3224 the function were treating the return as a boolean value, which happened to
3225 work because 0=false and not-0=true, but is not correct code.
3226
7e634d24
PH
322768. The host_aton() function was not handling scoped IPv6 addresses (those
3228 with, for example, "%eth0" on the end) correctly.
3229
3e11c26b
PH
323069. Fixed some compiler warnings in acl.c for the bitmaps specified with
3231 negated items (that is, ~something) in unsigned ints. Some compilers
3232 apparently mutter when there is no cast.
3233
6729cf78
PH
323470. If an address verification called from an ACL failed, and did not produce a
3235 user-specific message (i.e. there was only a "system" message), nothing was
3236 put in $acl_verify_message. In this situation, it now puts the system
3237 message there.
3238
00f00ca5
PH
323971. Change 4.23/11 added synchronization checking at the start of an SMTP
3240 session; change 4.31/43 added the unwanted input to the log line - except
3241 that it did not do this in the start of session case. It now does.
3242
c9bdd01c
PH
324372. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3244 This is wrong and can cause the other end to generate a synchronization
3245 error if it is another Exim or anything else that does the synchronization
3246 check. A QUIT command is no longer sent after a timeout.
3247
d43194df
PH
324873. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3249 during host lookups.
3250

PH
325174. The defer_ok option of callout verification was not working if it was used
3252 when verifying addresses in header lines, that is, for this case:
3253
3254 verify = header_sender/callout=defer_ok
3255
76a2d7ba
PH
325675. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3257 those file descriptors could be used for SMTP connections. If anything
3258 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3259 could be sent to the SMTP client, causing chaos. The daemon now opens
3260 stdin, stdout, and stderr to /dev/null when it puts itself into the
3261 background.
3262
326376. Arrange for output from Perl's "warn" command to be written to Exim's main
3264 log by default. The user can override this with suitable Perl magic.
3265
04f7d5b9
PH
326677. The use of log_message on a "discard" ACL verb, which is supposed to add to
3267 the log message when discard triggers, was not working for the DATA ACL or
3268 for the non-SMTP ACL.
3269
bc60667e
PH
327078. Error message wording change in sieve.c.
3271
bb6e88ff
PH
327279. If smtp_accept_max_per_host was set, the number of connections could be
3273 restricted to fewer than expected, because the daemon was trying to set up
3274 a new connection before checking whether the processes handling previous
3275 connections had finished. The check for completed processes is now done
3276 earlier. On busy systems, this bug wouldn't be noticed because something
3277 else would have woken the daemon, and it would have reaped the completed
3278 process earlier.
3279
1e70f85b
PH
328080. If a message was submitted locally by a user whose login name contained one
3281 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3282 It caused a spool format error. I have fixed the spool reading code. A
3283 related problem was that the "from" clause in the Received: line became
3284 illegal because of the space(s). It is now covered by ${quote_local_part.
3285
328681. Included the latest eximstats from Steve (adds average sizes to HTML Top
3287 tables).

3300----------------------------------------------------
3301See the note above about the 4.44 and 4.50 releases.
3302----------------------------------------------------
3303
3304
3305Exim version 4.44
3306-----------------
3307
3308 1. Change 4.43/35 introduced a bug that caused file counts to be
3309 incorrectly computed when quota_filecount was set in an appendfile
3310 transport
3311
3312 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3313 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3314 place.
3315
3316 3. Give more explanation in the error message when the command for a transport
3317 filter fails to execute.
3318
3319 4. There are several places where Exim runs a non-Exim command in a
3320 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3321 was being done only for the command run by the queryprogram router. It is
3322 now done for all such subprocesses. The other cases are: ${run, transport
3323 filters, and the commands run by the lmtp and pipe transports.
3324
3325 5. Some older OS have a limit of 256 on the maximum number of file
3326 descriptors. Exim was using setrlimit() to set 1000 as a large value
3327 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3328 systems. I've change it so that if it can't get 1000, it tries for 256.
3329
3330 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3331 was an oversight, and furthermore, ever since the addition of extra
3332 controls (e.g. 4.43/32), the checks on when to allow different forms of
3333 "control" were broken. There should now be diagnostics for all cases when a
3334 control that does not make sense is encountered.
3335
3336 7. $recipients is now available in the predata ACL (oversight).
3337
3338 8. Tidy the search cache before the fork to do a delivery from a message
3339 received from the command line. Otherwise the child will trigger a lookup
3340 failure and thereby defer the delivery if it tries to use (for example) a
3341 cached ldap connection that the parent has called unbind on.
3342
3343 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3344 of $address_data from the recipient verification was clobbered by the
3345 sender verification.
3346
334710. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3348 was its contents. (It was OK if the option was not defined at all.)
3349
335011. A "Completed" log line is now written for messages that are removed from
3351 the spool by the -Mrm option.
3352
335312. $host_address is now set to the target address during the checking of
3354 ignore_target_hosts.
3355
335613. When checking ignore_target_hosts for an ipliteral router, no host name was
3357 being passed; this would have caused $sender_host_name to have been used if
3358 matching the list had actually called for a host name (not very likely,
3359 since this list is usually IP addresses). A host name is now passed as
3360 "[x.x.x.x]".
3361
336214. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3363 code that specifies a non-restarting handler (typically sigaction() in
3364 modern systems) in an attempt to fix a rare and obscure crash bug.
3365
336615. Narrowed the window for a race in the daemon that could cause it to ignore
3367 SIGCHLD signals. This is not a major problem, because they are used only to
3368 wake it up if nothing else does.
3369
337016. A malformed maildirsize file could cause Exim to calculate negative values
3371 for the mailbox size or file count. Odd effects could occur as a result.
3372 The maildirsize information is now recalculated if the size or filecount
3373 end up negative.
3374
337517. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3376 support for a long time. Removed HAVE_SYS_VFS_H.
3377
ea3a6f44 337818. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3379
338019. Allow an empty sender to be matched against a lookup in an address list.
3381 Previously the only cases considered were a regular expression, or an
3382 empty pattern.
3383
338420. Exim went into a mad DNS lookup loop when doing a callout where the
3385 host was specified on the transport, if the DNS lookup yielded more than
3386 one IP address.
3387
ea3a6f44
NM
338821. The RFC2047 encoding function was originally intended for short strings
3389 such as real names; it was not keeping to the 75-character limit for
3390 encoded words that the RFC imposes. It now respects the limit, and
3391 generates multiple encoded words if necessary. To be on the safe side, I
3392 have increased the buffer size for the ${rfc2047: expansion operator from
3393 1024 to 2048 bytes.
bbe902f0 3394
ea3a6f44
NM
339522. Failure to deliver a bounce message always caused it to be frozen, even if
3396 there was an errors_to setting on the router. The errors_to setting is now
3397 respected.
bbe902f0
PH
3398
339923. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3400 canonical form (fully expanded) before being placed in
3401 $sender_host_address.
3402
340324. Updated eximstats to version 1.33
3404
ea3a6f44
NM
340525. Include certificate and key file names in error message when GnuTLS fails
3406 to set them up, because the GnuTLS error message doesn't include the name
3407 of the failing file when there is a problem reading it.
bbe902f0
PH
3408
340926. Expand error message when OpenSSL has problems setting up cert/key files.
ea3a6f44 3410 As per change 25.
bbe902f0 3411
ea3a6f44
NM
341227. Reset the locale to "C" after calling embedded Perl, in case it was
