TF
117TF/03 Make the exiwhat support code safe for signals. Previously Exim might
118 lock up or crash if it happened to be inside a call to libc when it
119 got a SIGUSR1 from exiwhat.
120
121 The SIGUSR1 handler appends the current process status to the process
122 log which is later printed by exiwhat. It used to use the general
123 purpose logging code to do this, but several functions it calls are
124 not safe for signals.
125
126 The new output code in the SIGUSR1 handler is specific to the process
127 log, and simple enough that it's easy to inspect for signal safety.
128 Removing some special cases also simplifies the general logging code.
129 Removing the spurious timestamps from the process log simplifies
130 exiwhat.
131
c99ce5c9
TF
132TF/04 Improved ratelimit ACL condition.
133
134 The /noupdate option has been deprecated in favour of /readonly which
135 has clearer semantics. The /leaky, /strict, and /readonly update modes
136 are mutually exclusive. The update mode is no longer included in the
137 database key; it just determines when the database is updated. (This
138 means that when you upgrde Exim will forget old rate measurements.)
139
140 Exim now checks that the per_* options are used with an update mode that
141 makes sense for the current ACL. For example, when Exim is processing a
142 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
143 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
144 must specify per_mail/readonly. If you omit the update mode it defaults to
145 /leaky where that makes sense (as before) or /readonly where required.
146
147 The /noupdate option is now undocumented but still supported for
148 backwards compatibility. It is equivalent to /readonly except that in
149 ACLs where /readonly is required you may specify /leaky/noupdate or
150 /strict/noupdate which are treated the same as /readonly.
151
152 A useful new feature is the /count= option. This is a generalization
153 of the per_byte option, so that you can measure the throughput of other
154 aggregate values. For example, the per_byte option is now equivalent
155 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
156
157 The per_rcpt option has been generalized using the /count= mechanism
158 (though it's more complicated than the per_byte equivalence). When it is
159 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
160 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
161 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
162 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
163 Note that using per_rcpt with a non-readonly update mode in more than
164 one ACL will cause the recipients to be double-counted. (The per_mail
165 and per_byte options don't have this problem.)
166
167 The handling of very low rates has changed slightly. If the computed rate
168 is less than the event's count (usually one) then this event is the first
169 after a long gap. In this case the rate is set to the same as this event's
170 count, so that the first message of a spam run is counted properly.
171
172 The major new feature is a mechanism for counting the rate of unique
173 events. The new per_addr option counts the number of different
174 recipients that someone has sent messages to in the last time period. It
175 behaves like per_rcpt if all the recipient addresses are different, but
176 duplicate recipient addresses do not increase the measured rate. Like
177 the /count= option this is a general mechanism, so the per_addr option
178 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
179 example, measure the rate that a client uses different sender addresses
180 with the options per_mail/unique=$sender_address. There are further
181 details in the main documentation.

753PH/01 Another patch from the Sieve maintainer.
754
6a3bceb1
PH
755PH/02 When an IPv6 address is converted to a string for single-key lookup
756 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
757 dots are used instead of colons so that keys in lsearch files need not
758 contain colons. This was done some time before quoting was made available
759 in lsearch files. However, iplsearch files do require colons in IPv6 keys
760 (notated using the quote facility) so as to distinguish them from IPv4
761 keys. This meant that lookups for IP addresses in host lists did not work
762 for iplsearch lookups.
763
764 This has been fixed by arranging for IPv6 addresses to be expressed with
765 colons if the lookup type is iplsearch. This is not incompatible, because
766 previously such lookups could never work.
767
768 The situation is now rather anomolous, since one *can* have colons in
769 ordinary lsearch keys. However, making the change in all cases is
770 incompatible and would probably break a number of configurations.

775MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
776 conversion specification without a maximum field width, thereby enabling
777 a rogue spamd server to cause a buffer overflow. While nobody in their
778 right mind would setup Exim to query an untrusted spamd server, an
779 attacker that gains access to a server running spamd could potentially
780 exploit this vulnerability to run arbitrary code as the Exim user.

MH
785MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
786 a directory entry by the name of the lookup key. Previously, if a
787 symlink pointed to a non-existing file or a file in a directory that
788 Exim lacked permissions to read, a lookup for a key matching that
789 symlink would fail. Now it is enough that a matching directory entry
790 exists, symlink or not. (Bugzilla 503.)

973PH/29 SMTP synchronization checks are implemented when a command is read -
974 there is a check that no more input is waiting when there shouldn't be

976 some time before the response is written. In this time, more input might
977 arrive, invalidly. So now there are extra checks after an ACL has run for
978 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
979 pipelining has not been advertised.

PH
1053 the response to the final '.' that terminates a message, but only in the
1054 case where the client has not sent further data following the '.'
1055 (unfortunately, this is allowed). However, in many cases there won't be
1056 any further data because there won't be any more messages to send. A call
1057 to select() can be used: if it shows that the input is "ready", there is
1058 either input waiting, or the socket has been closed. An attempt to read
1059 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1060 would have sent an OK response which the client would never have see.

1071PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1072 fixed by 4.65/MH/01 (is this a record?) are fixed:
1073
1074 (i) An empty string was always treated as zero by the numeric comparison
1075 operators. This behaviour has been restored.
1076
1077 (ii) It is documented that the numeric comparison operators always treat
1078 their arguments as decimal numbers. This was broken in that numbers
1079 starting with 0 were being interpreted as octal.
1080
1081 While fixing these problems I realized that there was another issue that
1082 hadn't been noticed. Values of message_size_limit (both the global option
1083 and the transport option) were treated as octal if they started with 0.
1084 The documentation was vague. These values are now always treated as
1085 decimal, and I will make that clear in the documentation.

1102 large number of recipients for a single message is ridiculous
1103 (performance will be very, very poor), I have chosen to impose a limit

2b1c6e3a
PH
1129PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1130 callout verification, Exim cached a "reject" for the entire domain. This
1131 is correct for most verifications, but it is not correct for a recipient
1132 verification with use_sender or use_postmaster set, because in that case
1133 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1134 case of MAIL FROM:<> rejection from other early rejections (e.g.
1135 rejection of HELO). When verifying a recipient using a non-null MAIL
1136 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1137 Whatever the result of the callout, the value of the domain cache is
1138 left unchanged (for any other kind of callout, getting as far as trying
1139 RCPT means that the domain itself is ok).

1175 probably the interface on which it is arriving) and not to the outgoing
1176 callout (which could be using a different interface). This has been
1177 changed to use the value of the helo_data option from the smtp transport
1178 instead - this is what is used when a message is actually being sent. If
1179 there is no remote transport (possible with a router that sets up host

14aa5a05
PH
1184 (a) The code assumed that strncpy() returns a negative number on buffer
1185 overflow, which isn't the case. Replaced with Exim's string_format()
1186 function.
1187 (b) There were several signed/unsigned issues. I just did the minimum
1188 hacking in of casts. There is scope for a larger refactoring.
1189 (c) The code used strcasecmp() which is not a standard C function.
1190 Replaced with Exim's strcmpic() function.
1191 (d) The code set only $1; it now sets $auth1 as well.
1192 (e) A simple test gave the error "authentication client didn't specify
1193 service in request". It would seem that Dovecot has changed its
1194 interface. Fortunately there's a specification; I followed it and
1195 changed what the client sends and it appears to be working now.

1201 address A is aliased to B and C, where B exists and C does not. Without
1202 -v the output is "A verified" because verification stops after a
1203 successful redirection if more than one address is generated. However,
1204 with -v the child addresses are also verified. Exim was outputting "A
1205 failed to verify" and then showing the successful verification for C,
1206 with its parentage. It now outputs "B failed to verify", showing B's
1207 parentage before showing the successful verification of C.

PH
1213PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1214 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1215 they consult the DNS. I had assumed they would set it the way they
1216 wanted; and indeed my experiments on Linux seem to show that in some
1217 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1218 To be on the safe side, however, I have now made the interface to
1219 host_find_byname() similar to host_find_bydns(), with an argument
1220 containing the DNS resolver options. The host_find_byname() function now
1221 sets these options at its start, just as host_find_bydns() does. The smtp
1222 transport options dns_qualify_single and dns_search_parents are passed to
1223 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1224 of host_find_byname() use the default settings of RES_DEFNAMES
1225 (qualify_single) but not RES_DNSRCH (search_parents).

1227PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1228 spool_read_header() do less string testing, by means of a preliminary
1229 switch on the second character of optional "-foo" lines. (This is
1230 overdue, caused by the large number of possibilities that now exist.
1231 Originally there were few.) While I was there, I also converted the
1232 str(n)cmp tests so they don't re-test the leading "-" and the first
1233 character, in the hope this might squeeze out yet more improvement.

1235PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1236 flag allowing group syntax was set by the header_syntax check but not
1237 turned off, possible causing trouble later; (2) The flag was not being
1238 set at all for the header_verify test, causing "group"-style headers to
1239 be rejected. I have now set it in this case, and also caused header_
1240 verify to ignore an empty address taken from a group. While doing this, I
1241 came across some other cases where the code for allowing group syntax
1242 while scanning a header line wasn't quite right (mostly, not resetting
1243 the flag correctly in the right place). These bugs could have caused
1244 trouble for malformed header lines. I hope it is now all correct.

1246PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1249 but it didn't always do it. This confused somebody who was copying the
1250 code for some other use. I have removed all the tests.

PH
1252PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1253 feature that was used to support insecure browsers during the U.S. crypto
1254 embargo. It requires special client support, and Exim is probably the
1255 only MTA that supported it -- and would never use it because real RSA is
1256 always available. This code has been removed, because it had the bad
1257 effect of slowing Exim down by computing (never used) parameters for the
1258 RSA_EXPORT functionality.

1263 to be base64-encoded). Also added, on Timo's advice, the "secured" option

1265 local IP, and the "valid-client-cert option" if a client certificate has
1266 been verified.

1297
1298PH/30 Exim was sometimes attempting to deliver messages that had suffered
1299 address errors (4xx response to RCPT) over the same connection as other
1300 messages routed to the same hosts. Such deliveries are always "forced",
1301 so retry times are not inspected. This resulted in far too many retries
1302 for the affected addresses. The effect occurred only when there were more
1303 hosts than the hosts_max_try setting in the smtp transport when it had
1304 the 4xx errors. Those hosts that it had tried were not added to the list
1305 of hosts for which the message was waiting, so if all were tried, there
1306 was no problem. Two fixes have been applied:
1307
1308 (i) If there are any address or message errors in an SMTP delivery, none
1309 of the hosts (tried or untried) are now added to the list of hosts
1310 for which the message is waiting, so the message should not be a
1311 candidate for sending over the same connection that was used for a
1312 successful delivery of some other message. This seems entirely
1313 reasonable: after all the message is NOT "waiting for some host".
1314 This is so "obvious" that I'm not sure why it wasn't done
1315 previously. Hope I haven't missed anything, but it can't do any
1316 harm, as the worst effect is to miss an optimization.
1317
1318 (ii) If, despite (i), such a delivery is accidentally attempted, the
1319 routing retry time is respected, so at least it doesn't keep
1320 hammering the server.

1335PH/35 The error "getsockname() failed: connection reset by peer" was being
1336 written to the panic log as well as the main log, but it isn't really

1338 removed the panic log writing for the ECONNRESET error when getsockname()
1339 fails.
1340
48c7f9e2
PH
1341PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1342 runs only) independently of the message's sender address. This meant
1343 that, if the 4xx error was in fact related to the sender, a different
1344 message to the same recipient with a different sender could confuse
1345 things. In particualar, this can happen when sending to a greylisting
1346 server, but other circumstances could also provoke similar problems.
1347 I have changed the default so that the retry time for these errors is now
1348 based a combination of the sender and recipient addresses. This change
1349 can be overridden by setting address_retry_include_sender=false in the
1350 smtp transport.

1618PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
1619 "Deny" causes Exim to reject the incoming connection with a 554 error.
1620 Unfortunately, if there is a major crisis, such as a disk failure,
1621 tcp-wrappers gives "deny", whereas what one would like would be some
1622 kind of temporary error. A kludge has been added to help with this.
1623 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1624 554 error is used if errno is still zero or contains ENOENT (which occurs
1625 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1626 451 error is used.

1651 used only to exclude .Trash (or whatever) when the size of the mailbox
1652 was calculated. There was no check that a delivery was happening into an

1662PH/01 The code for finding all the local interface addresses on a FreeBSD
1663 system running IPv6 was broken. This may well have applied to all BSD
1664 systems, as well as to others that have similar system calls. The broken
1665 code found IPv4 interfaces correctly, but gave incorrect values for the
1666 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1667 that it would not match correctly against @[] and not recognize the IPv6
1668 addresses as local.

1711 autoreply, Exim could try to deliver to a non-existent relative file

1733
1734 (a) Failures to set uid/gid, the current directory, or a process leader
1735 in a subprocess such as that created by queryprogram now generate
1736 suitable debugging ouput when -d is set.

1745PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1746 additional section of a DNS packet that returns MX or SRV records.
1747 Instead, it always explicitly searches for A/AAAA records. This avoids
1748 major problems that occur when a DNS server includes only records of one
1749 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1750 fixed another bug: if SRV records were looked up and the corresponding
1751 address records were *not* found in the additional section, the port
1752 values from the SRV records were lost.

1754PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
1762PH/19 When calculating a retry time, Exim used to measure the "time since
1763 failure" by looking at the "first failed" field in the retry record. Now
1764 it does not use this if it is later than than the arrival time of the
1765 message. Instead it uses the arrival time. This makes for better
1766 behaviour in cases where some deliveries succeed, thus re-setting the
1767 "first failed" field. An example is a quota failure for a huge message
1768 when small messages continue to be delivered. Without this change, the
1769 "time since failure" will always be short, possible causing more frequent
1770 delivery attempts for the huge message than are intended.

PH
1867PH/42 The content-scanning code uses fopen() to create files in which to put
1868 message data. Previously it was not paying any attention to the mode of
1869 the files. Exim runs with umask(0) because the rest of the code creates
1870 files with open(), and sets the required mode explicitly. Thus, these
1871 files were ending up world-writeable. This was not a big issue, because,
1872 being within the spool directory, they were not world-accessible. I have
1873 created a function called modefopen, which takes an additional mode
1874 argument. It sets umask(777), creates the file, chmods it to the required
1875 mode, then resets the umask. All the relevant calls to fopen() in the

1913
1914 (i) Exim was not creating retry information for temporary errors given

1916 was used in LMTP mode. This meant that they could be retried too
1917 frequently, and not timed out correctly.
1918
1919 (ii) Exim was setting the flag that allows error details to be returned
1920 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1921 recipients that were returned after the DATA command.
1922
1923PH/53 This is related to PH/52, but is more general: for any failing address,
1924 when detailed error information was permitted to be returned to the

1983PH/68 The bounce_return_message and bounce_return_body options were not being

1985 In particular, this applied to messages rejected by the ACL. This bug has
1986 been fixed. However, if bounce_return_message is true and bounce_return_
1987 body is false, the headers that are returned for a non-SMTP message
1988 include only those that have been read before the error was detected.

1997PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1998 function verify_get_ident() calls ip_connect() to connect a socket, but
1999 if the "connect()" function timed out, ip_connect() used to close the
2000 socket. However, verify_get_ident() also closes the socket later, and in
2001 between Exim writes to the log, which may get opened at this point. When
2002 the socket was closed in ip_connect(), the log could get the same file
2003 descriptor number as the socket. This naturally causes chaos. The fix is
2004 not to close the socket in ip_connect(); the socket should be closed by
2005 the function that creates it. There was only one place in the code where
2006 this was missing, in the iplookup router, which I don't think anybody now
2007 uses, but I've fixed it anyway.

2030
2031 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2032 string.
2033
2034 (3) Reset the variables that are obtained from the first argument of
2035 ${prvscheck and used in the second argument before leaving the code,
2036 because their memory is reclaimed, so using them afterwards may do
2037 silly things.
2038
2039 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2040 one (it's much easier than Tom thought :-).

2063PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2064 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2065 not being looked up in the rDNS to get a host name, Exim was showing the
2066 IP address twice in Received: lines, even though the IP addresses were
2067 identical. For example:
2068
2069 Received: from [1.2.3.4] (helo=[1.2.3.4])
2070
2071 However, if the real host name was known, it was omitting the HELO data
2072 if it matched the actual IP address. This has been tidied up so that it
2073 doesn't show the same IP address twice.

2099PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2101
2102 Auto-submitted: auto-generated
2103
2104 in the messages that it generates (bounce messages and others, such as
2105 warnings). In the case of bounce messages for non-SMTP mesages, there was
2106 also a typo: it was using "Auto_submitted" (underscore instead of
2107 hyphen). Since every message generated by Exim is necessarily in response
2108 to another message, thes have all been changed to:
2109
2110 Auto-Submitted: auto-replied
2111
2112 in accordance with these statements in the RFC:
2113
2114 The auto-replied keyword:
2115
2116 - SHOULD be used on messages sent in direct response to another
2117 message by an automatic process,
2118
2119 - MUST NOT be used on manually-generated messages,

2122 Disposition Notifications (MDNs),

2162PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated

2164 the IP address, check_host() was doing a simple string comparison with
2165 addresses acquired from the DNS when checking that the found name did
2166 have the original IP as one of its addresses. Since any found IPv6
2167 addresses are likely to be in abbreviated form, the comparison could
2168 fail. Luckily, there already exists a function for doing the comparison
2169 by converting both addresses to binary, so now that is used instead of
2170 the text comparison.

2467PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2468 with the definition in sysexits.h (which is #included earlier).
2469 Fortunately, Exim does not actually use EX_OK. The code used to try to
2470 preserve the sysexits.h value, by assumimg that macro definitions were
2471 scanned for macro replacements. I have been disabused of this notion,
2472 so now the code just undefines EX_OK before #including unistd.h.

2477 This seems wrong - if the receiver was accepting one byte at a time it
2478 would take for ever. The timeout is now adjusted when this happens. It
2479 doesn't have to be particularly precise.

2555 case the guess is not the same as the compiled default, so the script
2556 suddenly stopped working when I started to use syslog. The patch checks
2557 to see if log_file_path is "". If so, it attempts to read it from exim

2687
2688PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2689 that changes the way the GnuTLS parameters are stored in the cache file.
2690 The new format can be generated externally. For backward compatibility,
2691 if the data in the cache doesn't make sense, Exim assumes it has read an
2692 old-format file, and it generates new data and writes a new file. This
2693 means that you can't go back to an older release without removing the
2694 file.
2695
2696PH/03 A redirect router that has both "unseen" and "one_time" set does not
2697 work if there are any delivery delays because "one_time" forces the
2698 parent to be marked "delivered", so its unseen clone is never tried
2699 again. For this reason, Exim now forbids the simultaneous setting of
2700 these two options.
2701
2702PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2703 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2704 entry if you want to know the details. The fix, however, neglected to
2705 consider the case when local delivery batching is involved. The test for
2706 "previously delivered" was not happening when checking to see if an
2707 address could be batched with a previous (undelivered) one; under
2708 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2709 address.

PH
2710
2711PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2714PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2715 header_syntax) but Exim was just ignoring anything given after a slash.
2716 In particular, this caused confusion with an attempt to use "verify =
2717 reverse_host_lookup/defer_ok". An error is now given when options are
2718 supplied for verify items that do not have them. (Maybe reverse_host_
2719 lookup should have a defer_ok option, but that's a different point.)
2720
2721PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2774 the file with the wrong ownership). There was no test for failure of this
2775 fork() call, which would lead to the process getting stuck as it waited
2776 for a non-existent subprocess. Forks do occasionally fail when resources
2777 run out. I reviewed all the other calls to fork(); they all seem to check
2778 for failure.

2780PH/20 When checking for unexpected SMTP input at connect time (before writing
2781 the banner), Exim was not dealing correctly with a non-positive return
2782 from the read() function. If the client had disconnected by this time,
2783 the result was a log entry for a synchronization error with an empty
2784 string after "input=" when read() returned zero. If read() returned -1
2785 (an event I could not check), uninitialized data bytes were printed.
2786 There were reports of junk text (parts of files, etc) appearing after
2787 "input=".

PH
2797PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2798 hadn't been configured. The fix is from Juergen Kreileder, who
2799 understands it better than I do:
2800
2801 "Here's what I see happening with three configured cyrus_sasl
2802 authenticators configured (plain, login, cram-md5):
2803
2804 On startup auth_cyrus_sasl_init() gets called for each of these.
2805 This means three calls to sasl_listmech() without a specified mech_list.
2806 => SASL tests which mechs of all available mechs actually work
2807 => three warnings about OTP not working
2808 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2809
2810 With the patch, sasl_listmech() also gets called three times. But now
2811 SASL's mech_list option is set to the server_mech specified in the the
2812 authenticator. Or in other words, the answer from sasl_listmech()
2813 gets limited to just the mech you're testing for (which is different
2814 for each call.)
2815 => the return list contains just 'plain' or 'login', 'cram-md5' or
2816 nothing depending on the value of ob->server_mech.
2817
2818 I've just tested the patch: Authentication still works fine,
2819 unavailable mechs specified in the exim configuration are still
2820 caught, and the auth.log warnings about OTP are gone."

PH
2884PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2885 the grounds that routing the same address twice would always produce the
2886 same answer. This might have been true once, but it is certainly no
2887 longer true now. Routing a child address may depend on the previous
2888 routing that produced that child. Some complicated redirection strategies
2889 went wrong when messages had multiple recipients, and made Exim's
2890 behaviour dependent on the order in which the addresses were given.
2891
2892 I have moved the duplicate checking until after the routing is complete.
2893 Exim scans the addresses that are assigned to local and remote
2894 transports, and removes any duplicates. This means that more work will be
2895 done, as duplicates will always all be routed, but duplicates are
2896 presumably rare, so I don't expect this is of any significance.
2897
2898 For deliveries to pipes, files, and autoreplies, the duplicate checking
2899 still happens during the routing process, since they are not going to be
2900 routed further.

2945 consistency with the overall process timeout, these timeouts are now
2946 treated as errors, giving rise to delivery failures by default. However,
2947 there is now a new Boolean option for the pipe transport called

2959A note about Exim versions 4.44 and 4.50
2960----------------------------------------
2961
2962Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2963changes of various kinds. As a consequence, a big documentation update was
2964needed. This delayed the release for rather longer than seemed good, especially
2965in the light of a couple of (minor) security issues. Therefore, the changes
2966that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2967release. So 4.44 and 4.50 are in effect two different branches that both start
2968from 4.43.
2969
2970I have left the 4.50 change log unchanged; it contains all the changes since
29714.43. The change log for 4.44 is below; many of its items are identical to
2972those for 4.50. This seems to be the most sensible way to preserve the
2973historical information.

2991 5. There are several places where Exim runs a non-Exim command in a
2992 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2993 was being done only for the command run by the queryprogram router. It is
2994 now done for all such subprocesses. The other cases are: ${run, transport
2995 filters, and the commands run by the lmtp and pipe transports.

3000 descriptors. Exim was using setrlimit() to set 1000 as a large value
3001 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3002 systems. I've change it so that if it can't get 1000, it tries for 256.

3051
305223. When checking ignore_target_hosts for an ipliteral router, no host name was
3053 being passed; this would have caused $sender_host_name to have been used if
3054 matching the list had actually called for a host name (not very likely,
3055 since this list is usually IP addresses). A host name is now passed as
3056 "[x.x.x.x]".

3061
306225. Narrowed the window for a race in the daemon that could cause it to ignore

307629. In an address list, if the pattern was not a regular expression, an empty
3077 subject address (from a bounce message) matched only if the pattern was an
3078 empty string. Non-empty patterns were not even tested. This was the wrong
3079 because it is perfectly reasonable to use an empty address as part of a
3080 database query. An empty address is now tested by patterns that are
3081 lookups. However, all the other forms of pattern expect the subject to
3082 contain a local part and a domain, and therefore, for them, an empty
3083 address still always fails if the pattern is not itself empty.

PH
308530. Exim went into a mad DNS loop when attempting to do a callout where the

PH
308931. Re-factored the code for checking spool and log partition space into a
3090 function that finds that data and another that does the check. The former

3092 $spool_inodes, and $log_inodes.
3093

PH
309432. The RFC2047 encoding function was originally intended for short strings
3095 such as real names; it was not keeping to the 75-character limit for
3096 encoded words that the RFC imposes. It now respects the limit, and
3097 generates multiple encoded words if necessary. To be on the safe side, I
3098 have increased the buffer size for the ${rfc2047: expansion operator from
3099 1024 to 2048 bytes.
3100
063b1e99
PH
310133. It is now permitted to omit both strings after an "if" condition; if the
3102 condition is true, the result is "true". As before, when the second string
3103 is omitted, a false condition yields an empty string. This makes it less
3104 cumbersome to write custom ACL and router conditions.
3105
652e1b65
PH
310634. Failure to deliver a bounce message always caused it to be frozen, even if
3107 there was an errors_to setting on the router. The errors_to setting is now
3108 respected.

PH
311436. The table in the code that translates DNS record types into text (T_A to
3115 "A" for instance) was missing entries for NS and CNAME. It is just possible
3116 that this could have caused confusion if both these types were looked up
3117 for the same domain, because the text type is used as part of Exim's
3118 per-process caching. But the chance of anyone hitting this buglet seems
3119 very small.

PH
312137. The dnsdb lookup has been extended in a number of ways.

317149. The SPA authentication driver was not abandoning authentication and moving
3172 on to the next authenticator when an expansion was forced to fail,
3173 contradicting the general specification for all authenticators. Instead it
3174 was generating a temporary error. It now behaves as specified.
3175
26dd5a95
PH
317650. The default ordering of permitted cipher suites for GnuTLS was pessimal
3177 (the order specifies the preference for clients). The order is now AES256,
3178 AES128, 3DES, ARCFOUR128.
3179
343b2385
PH
318051. Small patch to Sieve code - explicitly set From: when generating an
3181 autoreply.
3182
1c5466b9
PH
318352. Exim crashed if a remote delivery caused a very long error message to be
3184 recorded - for instance if somebody sent an entire SpamAssassin report back
3185 as a large number of 550 error lines. This bug was coincidentally fixed by
3186 increasing the size of one of Exim's internal buffers (big_buffer) that
3187 happened as part of the Exiscan merge. However, to be on the safe side, I
3188 have made the code more robust (and fixed the comments that describe what
3189 is going on).
3190
55ee9ee3
PH
319153. Now that there can be additional text after "Completed" in log lines (if
3192 the queue_time_overall log selector is set), a one-byte patch to exigrep
3193 was needed to allow it to recognize "Completed" as not the last thing in
3194 the line.
3195
d38f8232
PH
319654. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3197 patch that reportedly fixes this has been added. I am not expert enough to
3198 create a test for it. This is what the patch creator wrote:
3199
3200 "I found a little strange behaviour of ldap code when working with
3201 Windows 2003 AD Domain, where users was placed in more than one
3202 Organization Units. When I tried to give exim partial DN, the exit code
3203 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3204 But simultaneously result of request was absolutely normal ldap result,
3205 so I produce this patch..."
3206
3295e65b
PH
3207 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3208 REFERENCE, so I have modified the code to exclude the patch when that macro
3209 is not defined.
3210
7102e136
PH
321155. Some experimental protocols are using DNS PTR records for new purposes. The
3212 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3213 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3214 leaves it alone. Component reversal etc. now happens only for IP addresses.

PH
321756. Improve error message when ldap_search() fails in OpenLDAP or Solaris LDAP.
3218
c2bcbe20
PH
321957. Double the size of the debug message buffer (to 2048) so that more of very
3220 long debug lines gets shown.
3221
18ce445d
PH
322258. The exicyclog utility now does better if the number of log files to keep
3223 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
3224
1f5b4c3d
PH
322559. Two changes related to the smtp_active_hostname option:
3226
3227 (1) $smtp_active_hostname is now available as a variable.
3228 (2) The default for smtp_banner uses $smtp_active_hostname instead
3229 of $primary_hostname.
3230
b975ba52
PH
323160. The host_aton() function is supposed to be passed a string that is known
3232 to be a valid IP address. However, in the case of IPv6 addresses, it was
3233 not checking this. This is a hostage to fortune. Exim now panics and dies
3234 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3235 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3236 components; fortuitously, this particular loophole had already been fixed
3237 by change 4.50/55 above.
3238
3239 If there are any other similar loopholes, the new check in host_aton()
3240 itself should stop them being exploited. The report I received stated that
3241 data on the command line could provoke the exploit when Exim was running as
3242 exim, but did not say which command line option was involved. All I could
3243 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3244 running as the user.

PH
3246
324761. There was a buffer overflow vulnerability in the SPA authentication code
3248 (which came originally from the Samba project). I have added a test to the
3249 spa_base64_to_bits() function which I hope fixes it.
ea3a6f44 3250 CAN-2005-0022

PH
325262. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
3253 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
3254
d95f9fdb
PH
325563. The daemon start-up calls getloadavg() while still root for those OS that
3256 need the first call to be done as root, but it missed one case: when
3257 deliver_queue_load_max is set with deliver_drop_privilege. This is
3258 necessary for the benefit of the queue runner, because there is no re-exec
3259 when deliver_drop_privilege is set.
3260
86b8287f
PH
326164. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3262 This has been fixed.
3263
60dc5e56
PH
326465. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3265 was in use, was not putting the data itself into the right store pool;
3266 consequently, it could be overwritten for a subsequent message in the same
3267 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3268 the caching.)
3269
533244af
PH
327066. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3271
a5a28604
PH
327267. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3273 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3274 the function were treating the return as a boolean value, which happened to
3275 work because 0=false and not-0=true, but is not correct code.
3276
7e634d24
PH
327768. The host_aton() function was not handling scoped IPv6 addresses (those
3278 with, for example, "%eth0" on the end) correctly.
3279
3e11c26b
PH
328069. Fixed some compiler warnings in acl.c for the bitmaps specified with
3281 negated items (that is, ~something) in unsigned ints. Some compilers
3282 apparently mutter when there is no cast.
3283
6729cf78
PH
328470. If an address verification called from an ACL failed, and did not produce a
3285 user-specific message (i.e. there was only a "system" message), nothing was
3286 put in $acl_verify_message. In this situation, it now puts the system
3287 message there.
3288
00f00ca5
PH
328971. Change 4.23/11 added synchronization checking at the start of an SMTP
3290 session; change 4.31/43 added the unwanted input to the log line - except
3291 that it did not do this in the start of session case. It now does.
3292
c9bdd01c
PH
329372. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3294 This is wrong and can cause the other end to generate a synchronization
3295 error if it is another Exim or anything else that does the synchronization
3296 check. A QUIT command is no longer sent after a timeout.
3297
d43194df
PH
329873. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3299 during host lookups.
3300
fe5b5d0b
PH
330174. The defer_ok option of callout verification was not working if it was used
3302 when verifying addresses in header lines, that is, for this case:
3303
3304 verify = header_sender/callout=defer_ok
3305
76a2d7ba
PH
330675. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3307 those file descriptors could be used for SMTP connections. If anything
3308 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3309 could be sent to the SMTP client, causing chaos. The daemon now opens
3310 stdin, stdout, and stderr to /dev/null when it puts itself into the
3311 background.
3312
331376. Arrange for output from Perl's "warn" command to be written to Exim's main
3314 log by default. The user can override this with suitable Perl magic.
3315
04f7d5b9
PH
331677. The use of log_message on a "discard" ACL verb, which is supposed to add to
3317 the log message when discard triggers, was not working for the DATA ACL or
3318 for the non-SMTP ACL.
3319
bc60667e
PH
332078. Error message wording change in sieve.c.
3321
bb6e88ff
PH
332279. If smtp_accept_max_per_host was set, the number of connections could be
3323 restricted to fewer than expected, because the daemon was trying to set up
3324 a new connection before checking whether the processes handling previous
3325 connections had finished. The check for completed processes is now done
3326 earlier. On busy systems, this bug wouldn't be noticed because something
3327 else would have woken the daemon, and it would have reaped the completed
3328 process earlier.
3329
1e70f85b
PH
333080. If a message was submitted locally by a user whose login name contained one
3331 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3332 It caused a spool format error. I have fixed the spool reading code. A
3333 related problem was that the "from" clause in the Received: line became
3334 illegal because of the space(s). It is now covered by ${quote_local_part.
3335
333681. Included the latest eximstats from Steve (adds average sizes to HTML Top
3337 tables).
3338
4e01f9d6
PH
333982. Updated OS/Makefile-AIX as per message from Mike Meredith.

3342 "vacation" handling.

334484. Some minor changes to the Linux configuration files to help with other
3345 OS variants using glibc.
3346

3350----------------------------------------------------
3351See the note above about the 4.44 and 4.50 releases.
3352----------------------------------------------------
3353
3354
3355Exim version 4.44
3356-----------------
3357
3358 1. Change 4.43/35 introduced a bug that caused file counts to be
3359 incorrectly computed when quota_filecount was set in an appendfile
3360 transport
3361
3362 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3363 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3364 place.
3365
3366 3. Give more explanation in the error message when the command for a transport
3367 filter fails to execute.
3368
3369 4. There are several places where Exim runs a non-Exim command in a
3370 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3371 was being done only for the command run by the queryprogram router. It is
3372 now done for all such subprocesses. The other cases are: ${run, transport
3373 filters, and the commands run by the lmtp and pipe transports.
3374
3375 5. Some older OS have a limit of 256 on the maximum number of file
3376 descriptors. Exim was using setrlimit() to set 1000 as a large value
3377 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3378 systems. I've change it so that if it can't get 1000, it tries for 256.
3379
3380 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3381 was an oversight, and furthermore, ever since the addition of extra
3382 controls (e.g. 4.43/32), the checks on when to allow different forms of
3383 "control" were broken. There should now be diagnostics for all cases when a
3384 control that does not make sense is encountered.
3385
3386 7. $recipients is now available in the predata ACL (oversight).
3387
3388 8. Tidy the search cache before the fork to do a delivery from a message
3389 received from the command line. Otherwise the child will trigger a lookup
3390 failure and thereby defer the delivery if it tries to use (for example) a
3391 cached ldap connection that the parent has called unbind on.
3392
3393 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3394 of $address_data from the recipient verification was clobbered by the
3395 sender verification.
3396
339710. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3398 was its contents. (It was OK if the option was not defined at all.)
3399
340011. A "Completed" log line is now written for messages that are removed from
3401 the spool by the -Mrm option.
3402
340312. $host_address is now set to the target address during the checking of
3404 ignore_target_hosts.
3405
