107PP/25 Revamped GnuTLS support, passing tls_require_ciphers to
108 gnutls_priority_init, ignoring Exim options gnutls_require_kx,
109 gnutls_require_mac & gnutls_require_protocols (no longer supported).

125PP/29 Fix three issues highlighted by clang analyser static analysis.
126 Only crash-plausible issue would require the Cambridge-specific

130PP/30 Another attempt to deal with PCRE_PRERELEASE, this one less buggy.
131
81f91683
PP
132PP/31 %D in printf continues to cause issues (-Wformat=security), so for
133 now guard some of the printf checks behind WANT_DEEPER_PRINTF_CHECKS.
134 As part of this, removing so much warning spew let me fix some minor
135 real issues in debug logging.
136
5779e6aa
PP
137PP/32 GnuTLS was always using default tls_require_ciphers, due to a missing
138 assignment on my part. Fixed.
139
3375e053
PP
140PP/33 Added tls_dh_max_bits option, defaulting to current hard-coded limit
141 of NSS, for GnuTLS/NSS interop. Problem root cause diagnosis by
142 Janne Snabb (who went above and beyond: thank you).
143
144PP/34 Validate tls_require_ciphers on startup, since debugging an invalid
145 string otherwise requires a connection and a bunch more work and it's
78e0c7a3
PP
146 relatively easy to get wrong. Should also expose TLS library linkage
147 problems.

162 when unlink() failed. See also change 4.74-TF/03.
163
921b12ca
TF
164TF/03 Make the exiwhat support code safe for signals. Previously Exim might
165 lock up or crash if it happened to be inside a call to libc when it
166 got a SIGUSR1 from exiwhat.
167
168 The SIGUSR1 handler appends the current process status to the process
169 log which is later printed by exiwhat. It used to use the general
170 purpose logging code to do this, but several functions it calls are
171 not safe for signals.
172
173 The new output code in the SIGUSR1 handler is specific to the process
174 log, and simple enough that it's easy to inspect for signal safety.
175 Removing some special cases also simplifies the general logging code.
176 Removing the spurious timestamps from the process log simplifies
177 exiwhat.
178
c99ce5c9
TF
179TF/04 Improved ratelimit ACL condition.
180
181 The /noupdate option has been deprecated in favour of /readonly which
182 has clearer semantics. The /leaky, /strict, and /readonly update modes
183 are mutually exclusive. The update mode is no longer included in the
184 database key; it just determines when the database is updated. (This
185 means that when you upgrde Exim will forget old rate measurements.)
186
187 Exim now checks that the per_* options are used with an update mode that
188 makes sense for the current ACL. For example, when Exim is processing a
189 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
190 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
191 must specify per_mail/readonly. If you omit the update mode it defaults to
192 /leaky where that makes sense (as before) or /readonly where required.
193
194 The /noupdate option is now undocumented but still supported for
195 backwards compatibility. It is equivalent to /readonly except that in
196 ACLs where /readonly is required you may specify /leaky/noupdate or
197 /strict/noupdate which are treated the same as /readonly.
198
199 A useful new feature is the /count= option. This is a generalization
200 of the per_byte option, so that you can measure the throughput of other
201 aggregate values. For example, the per_byte option is now equivalent
202 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
203
204 The per_rcpt option has been generalized using the /count= mechanism
205 (though it's more complicated than the per_byte equivalence). When it is
206 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
207 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
208 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
209 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
210 Note that using per_rcpt with a non-readonly update mode in more than
211 one ACL will cause the recipients to be double-counted. (The per_mail
212 and per_byte options don't have this problem.)
213
214 The handling of very low rates has changed slightly. If the computed rate
215 is less than the event's count (usually one) then this event is the first
216 after a long gap. In this case the rate is set to the same as this event's
217 count, so that the first message of a spam run is counted properly.
218
219 The major new feature is a mechanism for counting the rate of unique
220 events. The new per_addr option counts the number of different
221 recipients that someone has sent messages to in the last time period. It
222 behaves like per_rcpt if all the recipient addresses are different, but
223 duplicate recipient addresses do not increase the measured rate. Like
224 the /count= option this is a general mechanism, so the per_addr option
225 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
226 example, measure the rate that a client uses different sender addresses
227 with the options per_mail/unique=$sender_address. There are further
228 details in the main documentation.

438PP/06 Bugzilla 1071: fix delivery logging with untrusted macros.
439 If dropping privileges for untrusted macros, we disabled normal logging
440 on the basis that it would fail; for the Exim run-time user, this is not
441 the case, and it resulted in successful deliveries going unlogged.
442 Fixed. Reported by Andreas Metzler.

800PH/01 Another patch from the Sieve maintainer.
801
6a3bceb1
PH
802PH/02 When an IPv6 address is converted to a string for single-key lookup
803 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
804 dots are used instead of colons so that keys in lsearch files need not
805 contain colons. This was done some time before quoting was made available
806 in lsearch files. However, iplsearch files do require colons in IPv6 keys
807 (notated using the quote facility) so as to distinguish them from IPv4
808 keys. This meant that lookups for IP addresses in host lists did not work
809 for iplsearch lookups.
810
811 This has been fixed by arranging for IPv6 addresses to be expressed with
812 colons if the lookup type is iplsearch. This is not incompatible, because
813 previously such lookups could never work.
814
815 The situation is now rather anomolous, since one *can* have colons in
816 ordinary lsearch keys. However, making the change in all cases is
817 incompatible and would probably break a number of configurations.

MH
822MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
823 conversion specification without a maximum field width, thereby enabling
824 a rogue spamd server to cause a buffer overflow. While nobody in their
825 right mind would setup Exim to query an untrusted spamd server, an
826 attacker that gains access to a server running spamd could potentially
827 exploit this vulnerability to run arbitrary code as the Exim user.

829TK/02 Bugzilla 502: Apply patch to make the SPF-Received: header use
830 $primary_hostname instead of what libspf2 thinks the hosts name is.
831
0f2cbd1b
MH
832MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
833 a directory entry by the name of the lookup key. Previously, if a
834 symlink pointed to a non-existing file or a file in a directory that
835 Exim lacked permissions to read, a lookup for a key matching that
836 symlink would fail. Now it is enough that a matching directory entry
837 exists, symlink or not. (Bugzilla 503.)

PH
877PH/18 If a system quota error occurred while trying to create the file for
878 a maildir delivery, the message "Mailbox is full" was not appended to the
879 bounce if the delivery eventually timed out. Change 4.67/27 below applied
880 only to a quota excession during the actual writing of the file.
d6a60c0f 881
ddea74fa 882PH/19 It seems that peer DN values may contain newlines (and other non-printing

PH
910PH/02 In an ACL statement such as
911
912 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
913
914 if a client was not listed at all, or was listed with a value other than
915 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
916 the condition was not true (as it should be), so access was not denied.
917 The bug was that the ! inversion was incorrectly passed on to the second
918 item. This has been fixed.

921 = and & when the dns lookup returns more than one IP address.

PH
926PH/05 After discussion on the list, added a compile time option ENABLE_DISABLE_

933 with the auxiliary C programs that it uses: (1) Arrange for BIND_8_COMPAT
934 to be defined when compiling on OSX (Darwin); (2) Tidies to the Makefile,

0e8a9471
MH
938MH/02 Fix for bug #451, causing paniclog entries to be written if a bounce
939 message fails, move_frozen_messages = true and ignore_bounce_errors_after

f0872424
PH
942PH/07 There was a bug in the dovecot authenticator such that the value of
943 $auth1 could be overwritten, and so not correctly preserved, after a
944 successful authentication. This usually meant that the value preserved by
945 the server_setid option was incorrect.

PH
951PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
952 run for batched SMTP input. It is now run at the start of every message
953 in the batch. While fixing this I discovered that the process information
954 (output by running exiwhat) was not always getting set for -bs and -bS
955 input. This is fixed, and it now also says "batched" for BSMTP.

1006PH/27 When a message times out after an over-quota error from an Exim-imposed

MH
1011MH/03 Made $recipients available in local_scan(). local_scan() already has
1012 better access to the recipient list through recipients_list[], but

ca86f471
PH
1015PH/28 The $smtp_command and $smtp_command_argument variables were not correct
1016 in the case of a MAIL command with additional options following the

1018 were accidentally chopped off.
1019
a14e5636
PH
1020PH/29 SMTP synchronization checks are implemented when a command is read -
1021 there is a check that no more input is waiting when there shouldn't be
1022 any. However, for some commands, a delay in an ACL can mean that it is
1023 some time before the response is written. In this time, more input might
1024 arrive, invalidly. So now there are extra checks after an ACL has run for
1025 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1026 pipelining has not been advertised.

PH
1038PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1039 Exim which did not show up earlier: it was assuming that a call to
1040 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1041 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1042 was a macro that became an assignment, so it seemed to work. This has
1043 changed to a proper function call with a void return, hence the compile
1044 error. Exim's code has been fixed.

1055 "Completed" line in the log. When some messages of this type were

1058 criteria to be more general.

PH
1060PH/38 The host_find_failed option in the manualroute router can now be set
1061 to "ignore", to completely ignore a host whose IP address cannot be

cd9868ec
PH
1065PH/39 In a list of hosts for manualroute, if one item (either because of multi-
1066 homing or because of multiple MX records with /mx) generated more than
1067 one IP address, and the following item turned out to be the local host,
1068 all the secondary addresses of the first item were incorrectly removed
1069 from the list, along with the local host and any following hosts (which
1070 is what is supposed to happen).

ebeaf996
PH
1072PH/40 When Exim receives a message, it writes the login name, uid, and gid of
1073 whoever called Exim into the -H file. In the case of the daemon it was
1074 behaving confusingly. When first started, it used values for whoever
1075 started the daemon, but after a SIGHUP it used the Exim user (because it
1076 calls itself on a restart). I have changed the code so that it now always
1077 uses the Exim user.

PH
1079PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
1080 message are rejected with the same error (e.g. no authentication or bad
1081 sender address), and a DATA command is nevertheless sent (as can happen
1082 with PIPELINING or a stupid MUA), the error message that was given to the
1083 RCPT commands is included in the rejection of the DATA command. This is
1084 intended to be helpful for MUAs that show only the final error to their
1085 users.

PH
1100 the response to the final '.' that terminates a message, but only in the
1101 case where the client has not sent further data following the '.'
1102 (unfortunately, this is allowed). However, in many cases there won't be
1103 any further data because there won't be any more messages to send. A call
1104 to select() can be used: if it shows that the input is "ready", there is
1105 either input waiting, or the socket has been closed. An attempt to read
1106 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1107 would have sent an OK response which the client would never have see.

1116-----------------
1117
1118PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1119 fixed by 4.65/MH/01 (is this a record?) are fixed:
1120
1121 (i) An empty string was always treated as zero by the numeric comparison
1122 operators. This behaviour has been restored.
1123
1124 (ii) It is documented that the numeric comparison operators always treat
1125 their arguments as decimal numbers. This was broken in that numbers
1126 starting with 0 were being interpreted as octal.
1127
1128 While fixing these problems I realized that there was another issue that
1129 hadn't been noticed. Values of message_size_limit (both the global option
1130 and the transport option) were treated as octal if they started with 0.
1131 The documentation was vague. These values are now always treated as
1132 decimal, and I will make that clear in the documentation.

1148 is held in a short int, deliveries were likely to be lost. As such a
1149 large number of recipients for a single message is ridiculous
1150 (performance will be very, very poor), I have chosen to impose a limit
1151 rather than extend the field.

1157TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1158 leftover -K file (the existence of which was triggered by #402).
1159 While we were at it, introduced process PID as part of the -K
1160 filename. This should rule out race conditions when creating
1161 these files.

1163TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1164 processing considerably. Previous code took too long for large mails,
1165 triggering a timeout which in turn triggers #401.
1166
1167TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1168 in the DK code in transports.c. sendfile() is not really portable,

2b1c6e3a
PH
1176PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1177 callout verification, Exim cached a "reject" for the entire domain. This
1178 is correct for most verifications, but it is not correct for a recipient
1179 verification with use_sender or use_postmaster set, because in that case
1180 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1181 case of MAIL FROM:<> rejection from other early rejections (e.g.
1182 rejection of HELO). When verifying a recipient using a non-null MAIL
1183 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1184 Whatever the result of the callout, the value of the domain cache is
1185 left unchanged (for any other kind of callout, getting as far as trying
1186 RCPT means that the domain itself is ok).

1220PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1221 hostname. This is wrong, because it relates to the incoming message (and
1222 probably the interface on which it is arriving) and not to the outgoing
1223 callout (which could be using a different interface). This has been
1224 changed to use the value of the helo_data option from the smtp transport
1225 instead - this is what is used when a message is actually being sent. If
1226 there is no remote transport (possible with a router that sets up host
1227 addresses), $smtp_active_hostname is used.

14aa5a05 1229PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1230 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1231 (a) The code assumed that strncpy() returns a negative number on buffer
1232 overflow, which isn't the case. Replaced with Exim's string_format()
1233 function.
1234 (b) There were several signed/unsigned issues. I just did the minimum
1235 hacking in of casts. There is scope for a larger refactoring.
1236 (c) The code used strcasecmp() which is not a standard C function.
1237 Replaced with Exim's strcmpic() function.
1238 (d) The code set only $1; it now sets $auth1 as well.
1239 (e) A simple test gave the error "authentication client didn't specify
1240 service in request". It would seem that Dovecot has changed its
1241 interface. Fortunately there's a specification; I followed it and
1242 changed what the client sends and it appears to be working now.

1247PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1248 address A is aliased to B and C, where B exists and C does not. Without
1249 -v the output is "A verified" because verification stops after a
1250 successful redirection if more than one address is generated. However,
1251 with -v the child addresses are also verified. Exim was outputting "A
1252 failed to verify" and then showing the successful verification for C,
1253 with its parentage. It now outputs "B failed to verify", showing B's
1254 parentage before showing the successful verification of C.

1257 look up a TXT record in a specific list after matching in a combined

1259
322050c2
PH
1260PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1261 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1262 they consult the DNS. I had assumed they would set it the way they
1263 wanted; and indeed my experiments on Linux seem to show that in some
1264 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1265 To be on the safe side, however, I have now made the interface to
1266 host_find_byname() similar to host_find_bydns(), with an argument
1267 containing the DNS resolver options. The host_find_byname() function now
1268 sets these options at its start, just as host_find_bydns() does. The smtp
1269 transport options dns_qualify_single and dns_search_parents are passed to
1270 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1271 of host_find_byname() use the default settings of RES_DEFNAMES
1272 (qualify_single) but not RES_DNSRCH (search_parents).
1273

PH
1274PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1275 spool_read_header() do less string testing, by means of a preliminary
1276 switch on the second character of optional "-foo" lines. (This is
1277 overdue, caused by the large number of possibilities that now exist.
1278 Originally there were few.) While I was there, I also converted the
1279 str(n)cmp tests so they don't re-test the leading "-" and the first
1280 character, in the hope this might squeeze out yet more improvement.
1281

PH
1282PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1283 flag allowing group syntax was set by the header_syntax check but not
1284 turned off, possible causing trouble later; (2) The flag was not being
1285 set at all for the header_verify test, causing "group"-style headers to
1286 be rejected. I have now set it in this case, and also caused header_
1287 verify to ignore an empty address taken from a group. While doing this, I
1288 came across some other cases where the code for allowing group syntax
1289 while scanning a header line wasn't quite right (mostly, not resetting
1290 the flag correctly in the right place). These bugs could have caused
1291 trouble for malformed header lines. I hope it is now all correct.
1292
602e59e5
PH
1293PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1294 with the "reply" argument non-NULL. The code, however (which originally
1295 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1296 but it didn't always do it. This confused somebody who was copying the
1297 code for some other use. I have removed all the tests.
1298
411ef850
PH
1299PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1300 feature that was used to support insecure browsers during the U.S. crypto
1301 embargo. It requires special client support, and Exim is probably the
1302 only MTA that supported it -- and would never use it because real RSA is
1303 always available. This code has been removed, because it had the bad
1304 effect of slowing Exim down by computing (never used) parameters for the
1305 RSA_EXPORT functionality.
1306
7befa435
PH
1307PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1308 authenticator to fail if there's a tab character in the incoming data
1309 (there should never be unless someone is messing about, as it's supposed
1310 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1311 if the connection is using TLS or if the remote IP is the same as the
1312 local IP, and the "valid-client-cert option" if a client certificate has
1313 been verified.

PH
1344
1345PH/30 Exim was sometimes attempting to deliver messages that had suffered
1346 address errors (4xx response to RCPT) over the same connection as other
1347 messages routed to the same hosts. Such deliveries are always "forced",
1348 so retry times are not inspected. This resulted in far too many retries
1349 for the affected addresses. The effect occurred only when there were more
1350 hosts than the hosts_max_try setting in the smtp transport when it had
1351 the 4xx errors. Those hosts that it had tried were not added to the list
1352 of hosts for which the message was waiting, so if all were tried, there
1353 was no problem. Two fixes have been applied:
1354
1355 (i) If there are any address or message errors in an SMTP delivery, none
1356 of the hosts (tried or untried) are now added to the list of hosts
1357 for which the message is waiting, so the message should not be a
1358 candidate for sending over the same connection that was used for a
1359 successful delivery of some other message. This seems entirely
1360 reasonable: after all the message is NOT "waiting for some host".
1361 This is so "obvious" that I'm not sure why it wasn't done
1362 previously. Hope I haven't missed anything, but it can't do any
1363 harm, as the worst effect is to miss an optimization.
1364
1365 (ii) If, despite (i), such a delivery is accidentally attempted, the
1366 routing retry time is respected, so at least it doesn't keep
1367 hammering the server.

PH
1382PH/35 The error "getsockname() failed: connection reset by peer" was being
1383 written to the panic log as well as the main log, but it isn't really
1384 panic-worthy as it just means the connection died rather early on. I have
1385 removed the panic log writing for the ECONNRESET error when getsockname()
1386 fails.
1387
48c7f9e2
PH
1388PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1389 runs only) independently of the message's sender address. This meant
1390 that, if the 4xx error was in fact related to the sender, a different
1391 message to the same recipient with a different sender could confuse
1392 things. In particualar, this can happen when sending to a greylisting
1393 server, but other circumstances could also provoke similar problems.
1394 I have changed the default so that the retry time for these errors is now
1395 based a combination of the sender and recipient addresses. This change
1396 can be overridden by setting address_retry_include_sender=false in the
1397 smtp transport.

1665PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
1666 "Deny" causes Exim to reject the incoming connection with a 554 error.
1667 Unfortunately, if there is a major crisis, such as a disk failure,
1668 tcp-wrappers gives "deny", whereas what one would like would be some
1669 kind of temporary error. A kludge has been added to help with this.
1670 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1671 554 error is used if errno is still zero or contains ENOENT (which occurs
1672 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1673 451 error is used.

1695PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash

1697 up the contents of the maildirsize file. This was because the regex was
1698 used only to exclude .Trash (or whatever) when the size of the mailbox
1699 was calculated. There was no check that a delivery was happening into an
1700 excluded directory. This bug has been fixed by ignoring all quota

1709PH/01 The code for finding all the local interface addresses on a FreeBSD
1710 system running IPv6 was broken. This may well have applied to all BSD
1711 systems, as well as to others that have similar system calls. The broken
1712 code found IPv4 interfaces correctly, but gave incorrect values for the
1713 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1714 that it would not match correctly against @[] and not recognize the IPv6
1715 addresses as local.

1756 syntactically invalid From: or Reply-to: line, and a filter used this to
1757 generate an autoreply, and therefore failed to obtain an address for the
1758 autoreply, Exim could try to deliver to a non-existent relative file
1759 name, causing unrelated and misleading errors. What now happens is that
1760 it logs this as a hard delivery error, but does not attempt to create a

1775PH/14 When a uid/gid is specified for the queryprogram router, it cannot be

1778 non-existent - all you got was a failure to exec. I have made two
1779 changes:
1780
1781 (a) Failures to set uid/gid, the current directory, or a process leader
1782 in a subprocess such as that created by queryprogram now generate
1783 suitable debugging ouput when -d is set.
1784
1785 (b) The queryprogram router detects when it is not running as root,
1786 outputs suitable debugging information if -d is set, and then runs
1787 the subprocess without attempting to change uid/gid.

1792PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1793 additional section of a DNS packet that returns MX or SRV records.
1794 Instead, it always explicitly searches for A/AAAA records. This avoids
1795 major problems that occur when a DNS server includes only records of one
1796 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1797 fixed another bug: if SRV records were looked up and the corresponding
1798 address records were *not* found in the additional section, the port
1799 values from the SRV records were lost.

1801PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

1808
727071f8
PH
1809PH/19 When calculating a retry time, Exim used to measure the "time since
1810 failure" by looking at the "first failed" field in the retry record. Now
1811 it does not use this if it is later than than the arrival time of the
1812 message. Instead it uses the arrival time. This makes for better
1813 behaviour in cases where some deliveries succeed, thus re-setting the
1814 "first failed" field. An example is a quota failure for a huge message
1815 when small messages continue to be delivered. Without this change, the
1816 "time since failure" will always be short, possible causing more frequent
1817 delivery attempts for the huge message than are intended.

PH
1914PH/42 The content-scanning code uses fopen() to create files in which to put
1915 message data. Previously it was not paying any attention to the mode of
1916 the files. Exim runs with umask(0) because the rest of the code creates
1917 files with open(), and sets the required mode explicitly. Thus, these
1918 files were ending up world-writeable. This was not a big issue, because,
1919 being within the spool directory, they were not world-accessible. I have
1920 created a function called modefopen, which takes an additional mode
1921 argument. It sets umask(777), creates the file, chmods it to the required
1922 mode, then resets the umask. All the relevant calls to fopen() in the
1923 content scanning code have been changed to use this function.

2044PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2045 function verify_get_ident() calls ip_connect() to connect a socket, but
2046 if the "connect()" function timed out, ip_connect() used to close the
2047 socket. However, verify_get_ident() also closes the socket later, and in
2048 between Exim writes to the log, which may get opened at this point. When
2049 the socket was closed in ip_connect(), the log could get the same file
2050 descriptor number as the socket. This naturally causes chaos. The fix is
2051 not to close the socket in ip_connect(); the socket should be closed by
2052 the function that creates it. There was only one place in the code where
2053 this was missing, in the iplookup router, which I don't think anybody now
2054 uses, but I've fixed it anyway.

2077
2078 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2079 string.
2080
2081 (3) Reset the variables that are obtained from the first argument of
2082 ${prvscheck and used in the second argument before leaving the code,
2083 because their memory is reclaimed, so using them afterwards may do
2084 silly things.
2085
2086 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2087 one (it's much easier than Tom thought :-).

2110PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2111 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2112 not being looked up in the rDNS to get a host name, Exim was showing the
2113 IP address twice in Received: lines, even though the IP addresses were
2114 identical. For example:
2115
2116 Received: from [1.2.3.4] (helo=[1.2.3.4])
2117
2118 However, if the real host name was known, it was omitting the HELO data
2119 if it matched the actual IP address. This has been tidied up so that it
2120 doesn't show the same IP address twice.

2149 Auto-submitted: auto-generated
2150
2151 in the messages that it generates (bounce messages and others, such as
2152 warnings). In the case of bounce messages for non-SMTP mesages, there was
2153 also a typo: it was using "Auto_submitted" (underscore instead of
2154 hyphen). Since every message generated by Exim is necessarily in response
2155 to another message, thes have all been changed to:
2156
2157 Auto-Submitted: auto-replied
2158
2159 in accordance with these statements in the RFC:
2160
2161 The auto-replied keyword:
2162
2163 - SHOULD be used on messages sent in direct response to another

2209PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2210 canonical form (as documented). However, after a host name lookup from
2211 the IP address, check_host() was doing a simple string comparison with
2212 addresses acquired from the DNS when checking that the found name did
2213 have the original IP as one of its addresses. Since any found IPv6
2214 addresses are likely to be in abbreviated form, the comparison could
2215 fail. Luckily, there already exists a function for doing the comparison
2216 by converting both addresses to binary, so now that is used instead of
2217 the text comparison.

2514PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2515 with the definition in sysexits.h (which is #included earlier).
2516 Fortunately, Exim does not actually use EX_OK. The code used to try to
2517 preserve the sysexits.h value, by assumimg that macro definitions were
2518 scanned for macro replacements. I have been disabused of this notion,
2519 so now the code just undefines EX_OK before #including unistd.h.

2524 This seems wrong - if the receiver was accepting one byte at a time it
2525 would take for ever. The timeout is now adjusted when this happens. It
2526 doesn't have to be particularly precise.

2601 the logs files are, rather than using the compiled in default. In our
2602 case the guess is not the same as the compiled default, so the script
2603 suddenly stopped working when I started to use syslog. The patch checks
2604 to see if log_file_path is "". If so, it attempts to read it from exim
2605 with no configuration file to get the compiled in version, before it
2606 falls back to the previous guessing code."

2662PH/27 If a dnslookup or manualroute router is set with verify=only, it need not

2665 read the rcpt_include_affixes from the non-existent transport. Now it

2734
2735PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2736 that changes the way the GnuTLS parameters are stored in the cache file.
2737 The new format can be generated externally. For backward compatibility,
2738 if the data in the cache doesn't make sense, Exim assumes it has read an
2739 old-format file, and it generates new data and writes a new file. This
2740 means that you can't go back to an older release without removing the
2741 file.
2742
2743PH/03 A redirect router that has both "unseen" and "one_time" set does not
2744 work if there are any delivery delays because "one_time" forces the
2745 parent to be marked "delivered", so its unseen clone is never tried
2746 again. For this reason, Exim now forbids the simultaneous setting of
2747 these two options.
2748
2749PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2750 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2751 entry if you want to know the details. The fix, however, neglected to
2752 consider the case when local delivery batching is involved. The test for
2753 "previously delivered" was not happening when checking to see if an
2754 address could be batched with a previous (undelivered) one; under
2755 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2756 address.

PH
2757
2758PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2760
2761PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2762 header_syntax) but Exim was just ignoring anything given after a slash.
2763 In particular, this caused confusion with an attempt to use "verify =
2764 reverse_host_lookup/defer_ok". An error is now given when options are
2765 supplied for verify items that do not have them. (Maybe reverse_host_
2766 lookup should have a defer_ok option, but that's a different point.)
2767
2768PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
2769 defined by RFC 821) to 2048, because there were problems with some AUTH

2818PH/19 When an Exim process that is running as root has to create an Exim log
2819 file, it does so in a subprocess that runs as exim:exim so as to get the
2820 ownership right at creation (otherwise, other Exim processes might see
2821 the file with the wrong ownership). There was no test for failure of this
2822 fork() call, which would lead to the process getting stuck as it waited
2823 for a non-existent subprocess. Forks do occasionally fail when resources
2824 run out. I reviewed all the other calls to fork(); they all seem to check
2825 for failure.

2827PH/20 When checking for unexpected SMTP input at connect time (before writing
2828 the banner), Exim was not dealing correctly with a non-positive return
2829 from the read() function. If the client had disconnected by this time,
2830 the result was a log entry for a synchronization error with an empty
2831 string after "input=" when read() returned zero. If read() returned -1
2832 (an event I could not check), uninitialized data bytes were printed.

2843
c5ddb310
PH
2844PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2845 hadn't been configured. The fix is from Juergen Kreileder, who
2846 understands it better than I do:
2847
2848 "Here's what I see happening with three configured cyrus_sasl
2849 authenticators configured (plain, login, cram-md5):
2850
2851 On startup auth_cyrus_sasl_init() gets called for each of these.
2852 This means three calls to sasl_listmech() without a specified mech_list.
2853 => SASL tests which mechs of all available mechs actually work
2854 => three warnings about OTP not working
2855 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2856
2857 With the patch, sasl_listmech() also gets called three times. But now
2858 SASL's mech_list option is set to the server_mech specified in the the
2859 authenticator. Or in other words, the answer from sasl_listmech()
2860 gets limited to just the mech you're testing for (which is different
2861 for each call.)
2862 => the return list contains just 'plain' or 'login', 'cram-md5' or
2863 nothing depending on the value of ob->server_mech.
2864
2865 I've just tested the patch: Authentication still works fine,
2866 unavailable mechs specified in the exim configuration are still
2867 caught, and the auth.log warnings about OTP are gone."

d7174846
PH
2931PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2932 the grounds that routing the same address twice would always produce the
2933 same answer. This might have been true once, but it is certainly no
2934 longer true now. Routing a child address may depend on the previous
2935 routing that produced that child. Some complicated redirection strategies
2936 went wrong when messages had multiple recipients, and made Exim's
2937 behaviour dependent on the order in which the addresses were given.
2938
2939 I have moved the duplicate checking until after the routing is complete.
2940 Exim scans the addresses that are assigned to local and remote
2941 transports, and removes any duplicates. This means that more work will be
2942 done, as duplicates will always all be routed, but duplicates are
2943 presumably rare, so I don't expect this is of any significance.
2944
2945 For deliveries to pipes, files, and autoreplies, the duplicate checking
2946 still happens during the routing process, since they are not going to be
2947 routed further.

2992 consistency with the overall process timeout, these timeouts are now
2993 treated as errors, giving rise to delivery failures by default. However,
2994 there is now a new Boolean option for the pipe transport called
2995 timeout_defer, which, if set TRUE, converts the failures into defers for
2996 both kinds of timeout. A transport filter timeout is now identified in

3006A note about Exim versions 4.44 and 4.50
3007----------------------------------------
3008
3009Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3010changes of various kinds. As a consequence, a big documentation update was
3011needed. This delayed the release for rather longer than seemed good, especially
3012in the light of a couple of (minor) security issues. Therefore, the changes
3013that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3014release. So 4.44 and 4.50 are in effect two different branches that both start
3015from 4.43.
3016
3017I have left the 4.50 change log unchanged; it contains all the changes since
30184.43. The change log for 4.44 is below; many of its items are identical to
3019those for 4.50. This seems to be the most sensible way to preserve the
3020historical information.

3038 5. There are several places where Exim runs a non-Exim command in a
3039 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3040 was being done only for the command run by the queryprogram router. It is
3041 now done for all such subprocesses. The other cases are: ${run, transport
3042 filters, and the commands run by the lmtp and pipe transports.

3046 7. Some older OS have a limit of 256 on the maximum number of file
3047 descriptors. Exim was using setrlimit() to set 1000 as a large value
3048 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3049 systems. I've change it so that if it can't get 1000, it tries for 256.

3097 ignore_target_hosts.
3098
309923. When checking ignore_target_hosts for an ipliteral router, no host name was
3100 being passed; this would have caused $sender_host_name to have been used if
3101 matching the list had actually called for a host name (not very likely,
3102 since this list is usually IP addresses). A host name is now passed as
3103 "[x.x.x.x]".

3108
310925. Narrowed the window for a race in the daemon that could cause it to ignore

312329. In an address list, if the pattern was not a regular expression, an empty
3124 subject address (from a bounce message) matched only if the pattern was an
3125 empty string. Non-empty patterns were not even tested. This was the wrong
3126 because it is perfectly reasonable to use an empty address as part of a
3127 database query. An empty address is now tested by patterns that are
3128 lookups. However, all the other forms of pattern expect the subject to
3129 contain a local part and a domain, and therefore, for them, an empty
3130 address still always fails if the pattern is not itself empty.

313230. Exim went into a mad DNS loop when attempting to do a callout where the

PH
313631. Re-factored the code for checking spool and log partition space into a
3137 function that finds that data and another that does the check. The former

3139 $spool_inodes, and $log_inodes.

PH
314132. The RFC2047 encoding function was originally intended for short strings
3142 such as real names; it was not keeping to the 75-character limit for
3143 encoded words that the RFC imposes. It now respects the limit, and
3144 generates multiple encoded words if necessary. To be on the safe side, I
3145 have increased the buffer size for the ${rfc2047: expansion operator from
3146 1024 to 2048 bytes.
3147

PH
314833. It is now permitted to omit both strings after an "if" condition; if the
3149 condition is true, the result is "true". As before, when the second string
3150 is omitted, a false condition yields an empty string. This makes it less
3151 cumbersome to write custom ACL and router conditions.
3152

PH
315334. Failure to deliver a bounce message always caused it to be frozen, even if
3154 there was an errors_to setting on the router. The errors_to setting is now

316136. The table in the code that translates DNS record types into text (T_A to
3162 "A" for instance) was missing entries for NS and CNAME. It is just possible
3163 that this could have caused confusion if both these types were looked up
3164 for the same domain, because the text type is used as part of Exim's
3165 per-process caching. But the chance of anyone hitting this buglet seems
3166 very small.

PH
316837. The dnsdb lookup has been extended in a number of ways.
3169
3170 (1) There is a new type, "zns", which walks up the domain tree until it
3171 finds some nameserver records. It should be used with care.
3172
ea3bc19b
PH
3173 (2) There is a new type, "mxh", which is like "mx" except that it returns
3174 just the host names, not the priorities.
3175
3176 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
3177 looked up. The behaviour when one of the lookups defers can be
3178 controlled by a keyword.
7bb56e1f 3179
ea3bc19b 3180 (4) It is now possible to specify the separator character for use when
7bb56e1f 3181 multiple records are returned.
33397d19 3182
0bcb2a0e
PH
318338. The dnslists ACL condition has been extended: it is now possible to supply
3184 a list of IP addresses and/or domains to be looked up in a particular DNS
3185 domain.
3186
2ac0e484
PH
318739. Added log_selector=+queue_time_overall.
3188
4e1fde53
PH
318940. When running the queue in the test harness, wait just a tad after forking a
3190 delivery process, to get repeatability of debugging output.
3191
de365ded
PH
319241. Include certificate and key file names in error message when GnuTLS fails
3193 to set them up, because the GnuTLS error message doesn't include the name
3194 of the failing file when there is a problem reading it.
3195
f05da2e8
PH
319642. Allow both -bf and -bF in the same test run.
3197
d6453af2
PH
319843. Did the same fix as 41 above for OpenSSL, which had the same infelicity.
3199
f7b63901
PH
320044. The "Exiscan patch" is now merged into the mainline Exim source.
3201
320245. Sometimes the final signoff response after QUIT could fail to get
3203 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3204 < 0 before doing a fflush(). This bug looks as though it goes back to the
3205 introduction of TLS in release 3.20, but "sometimes" must have been rare
3206 because the tests only now provoked it.
3207
a444213a
PH
320846. Reset the locale to "C" after calling embedded Perl, in case it was changed
3209 (this can affect the format of dates).
3210
0ec020ea
PH
321147. exim_tidydb, when checking for the continued existence of a message for
3212 which it has found a message-specific retry record, was not finding
3213 messages that were in split spool directories. Consequently, it was
3214 deleting retry records that should have stayed in existence.
3215
b1206957
PH
321648. Steve fixed some bugs in eximstats.
3217
321849. The SPA authentication driver was not abandoning authentication and moving
3219 on to the next authenticator when an expansion was forced to fail,
3220 contradicting the general specification for all authenticators. Instead it
3221 was generating a temporary error. It now behaves as specified.
3222
26dd5a95
PH
322350. The default ordering of permitted cipher suites for GnuTLS was pessimal
3224 (the order specifies the preference for clients). The order is now AES256,
3225 AES128, 3DES, ARCFOUR128.
3226
343b2385
PH
322751. Small patch to Sieve code - explicitly set From: when generating an
3228 autoreply.
3229
1c5466b9
PH
323052. Exim crashed if a remote delivery caused a very long error message to be
3231 recorded - for instance if somebody sent an entire SpamAssassin report back
3232 as a large number of 550 error lines. This bug was coincidentally fixed by
3233 increasing the size of one of Exim's internal buffers (big_buffer) that
3234 happened as part of the Exiscan merge. However, to be on the safe side, I
3235 have made the code more robust (and fixed the comments that describe what
3236 is going on).
3237
55ee9ee3
PH
323853. Now that there can be additional text after "Completed" in log lines (if
3239 the queue_time_overall log selector is set), a one-byte patch to exigrep
3240 was needed to allow it to recognize "Completed" as not the last thing in
3241 the line.
3242
d38f8232
PH
324354. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3244 patch that reportedly fixes this has been added. I am not expert enough to
3245 create a test for it. This is what the patch creator wrote:
3246
3247 "I found a little strange behaviour of ldap code when working with
3248 Windows 2003 AD Domain, where users was placed in more than one
3249 Organization Units. When I tried to give exim partial DN, the exit code
3250 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3251 But simultaneously result of request was absolutely normal ldap result,
3252 so I produce this patch..."
3253
3295e65b
PH
3254 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3255 REFERENCE, so I have modified the code to exclude the patch when that macro
3256 is not defined.
3257
7102e136
PH
325855. Some experimental protocols are using DNS PTR records for new purposes. The
3259 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3260 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3261 leaves it alone. Component reversal etc. now happens only for IP addresses.

PH
326456. Improve error message when ldap_search() fails in OpenLDAP or Solaris LDAP.
3265
c2bcbe20
PH
326657. Double the size of the debug message buffer (to 2048) so that more of very
3267 long debug lines gets shown.
3268
18ce445d
PH
326958. The exicyclog utility now does better if the number of log files to keep
3270 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
3271
1f5b4c3d
PH
327259. Two changes related to the smtp_active_hostname option:
3273
3274 (1) $smtp_active_hostname is now available as a variable.
3275 (2) The default for smtp_banner uses $smtp_active_hostname instead
3276 of $primary_hostname.
3277
b975ba52
PH
327860. The host_aton() function is supposed to be passed a string that is known
3279 to be a valid IP address. However, in the case of IPv6 addresses, it was
3280 not checking this. This is a hostage to fortune. Exim now panics and dies
3281 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3282 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3283 components; fortuitously, this particular loophole had already been fixed
3284 by change 4.50/55 above.
3285
3286 If there are any other similar loopholes, the new check in host_aton()
3287 itself should stop them being exploited. The report I received stated that
3288 data on the command line could provoke the exploit when Exim was running as
3289 exim, but did not say which command line option was involved. All I could
3290 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3291 running as the user.

PH
3293
329461. There was a buffer overflow vulnerability in the SPA authentication code
3295 (which came originally from the Samba project). I have added a test to the
3296 spa_base64_to_bits() function which I hope fixes it.
ea3a6f44 3297 CAN-2005-0022
b975ba52 3298

PH
329962. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
3300 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
3301
d95f9fdb
PH
330263. The daemon start-up calls getloadavg() while still root for those OS that
3303 need the first call to be done as root, but it missed one case: when
3304 deliver_queue_load_max is set with deliver_drop_privilege. This is
3305 necessary for the benefit of the queue runner, because there is no re-exec
3306 when deliver_drop_privilege is set.
3307
86b8287f
PH
330864. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3309 This has been fixed.
3310
60dc5e56
PH
331165. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3312 was in use, was not putting the data itself into the right store pool;
3313 consequently, it could be overwritten for a subsequent message in the same
3314 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3315 the caching.)
3316
533244af
PH
331766. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3318
a5a28604
PH
331967. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3320 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3321 the function were treating the return as a boolean value, which happened to
3322 work because 0=false and not-0=true, but is not correct code.
3323
7e634d24
PH
332468. The host_aton() function was not handling scoped IPv6 addresses (those
3325 with, for example, "%eth0" on the end) correctly.
3326
3e11c26b
PH
332769. Fixed some compiler warnings in acl.c for the bitmaps specified with
3328 negated items (that is, ~something) in unsigned ints. Some compilers
3329 apparently mutter when there is no cast.
3330
6729cf78
PH
333170. If an address verification called from an ACL failed, and did not produce a
3332 user-specific message (i.e. there was only a "system" message), nothing was
3333 put in $acl_verify_message. In this situation, it now puts the system
3334 message there.
3335
00f00ca5
PH
333671. Change 4.23/11 added synchronization checking at the start of an SMTP
3337 session; change 4.31/43 added the unwanted input to the log line - except
3338 that it did not do this in the start of session case. It now does.
3339
c9bdd01c
PH
334072. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3341 This is wrong and can cause the other end to generate a synchronization
3342 error if it is another Exim or anything else that does the synchronization
3343 check. A QUIT command is no longer sent after a timeout.
3344
d43194df
PH
334573. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3346 during host lookups.
3347
fe5b5d0b
PH
334874. The defer_ok option of callout verification was not working if it was used
3349 when verifying addresses in header lines, that is, for this case:
3350
3351 verify = header_sender/callout=defer_ok
3352
76a2d7ba
PH
335375. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3354 those file descriptors could be used for SMTP connections. If anything
3355 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3356 could be sent to the SMTP client, causing chaos. The daemon now opens
3357 stdin, stdout, and stderr to /dev/null when it puts itself into the
3358 background.
3359
336076. Arrange for output from Perl's "warn" command to be written to Exim's main
3361 log by default. The user can override this with suitable Perl magic.
3362
04f7d5b9
PH
336377. The use of log_message on a "discard" ACL verb, which is supposed to add to
3364 the log message when discard triggers, was not working for the DATA ACL or
3365 for the non-SMTP ACL.
3366
bc60667e
PH
336778. Error message wording change in sieve.c.
3368
bb6e88ff
PH
336979. If smtp_accept_max_per_host was set, the number of connections could be
3370 restricted to fewer than expected, because the daemon was trying to set up
3371 a new connection before checking whether the processes handling previous
3372 connections had finished. The check for completed processes is now done
3373 earlier. On busy systems, this bug wouldn't be noticed because something
3374 else would have woken the daemon, and it would have reaped the completed
3375 process earlier.
3376
1e70f85b
PH
337780. If a message was submitted locally by a user whose login name contained one
3378 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3379 It caused a spool format error. I have fixed the spool reading code. A
3380 related problem was that the "from" clause in the Received: line became
3381 illegal because of the space(s). It is now covered by ${quote_local_part.
3382
338381. Included the latest eximstats from Steve (adds average sizes to HTML Top
3384 tables).

338682. Updated OS/Makefile-AIX as per message from Mike Meredith.
