131

TF
132TF/03 Make the exiwhat support code safe for signals. Previously Exim might
133 lock up or crash if it happened to be inside a call to libc when it
134 got a SIGUSR1 from exiwhat.
135
136 The SIGUSR1 handler appends the current process status to the process
137 log which is later printed by exiwhat. It used to use the general
138 purpose logging code to do this, but several functions it calls are
139 not safe for signals.
140
141 The new output code in the SIGUSR1 handler is specific to the process
142 log, and simple enough that it's easy to inspect for signal safety.
143 Removing some special cases also simplifies the general logging code.
144 Removing the spurious timestamps from the process log simplifies
145 exiwhat.
146
c99ce5c9
TF
147TF/04 Improved ratelimit ACL condition.
148
149 The /noupdate option has been deprecated in favour of /readonly which
150 has clearer semantics. The /leaky, /strict, and /readonly update modes
151 are mutually exclusive. The update mode is no longer included in the
152 database key; it just determines when the database is updated. (This
153 means that when you upgrde Exim will forget old rate measurements.)
154
155 Exim now checks that the per_* options are used with an update mode that
156 makes sense for the current ACL. For example, when Exim is processing a
157 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
158 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
159 must specify per_mail/readonly. If you omit the update mode it defaults to
160 /leaky where that makes sense (as before) or /readonly where required.
161
162 The /noupdate option is now undocumented but still supported for
163 backwards compatibility. It is equivalent to /readonly except that in
164 ACLs where /readonly is required you may specify /leaky/noupdate or
165 /strict/noupdate which are treated the same as /readonly.
166
167 A useful new feature is the /count= option. This is a generalization
168 of the per_byte option, so that you can measure the throughput of other
169 aggregate values. For example, the per_byte option is now equivalent
170 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
171
172 The per_rcpt option has been generalized using the /count= mechanism
173 (though it's more complicated than the per_byte equivalence). When it is
174 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
175 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
176 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
177 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
178 Note that using per_rcpt with a non-readonly update mode in more than
179 one ACL will cause the recipients to be double-counted. (The per_mail
180 and per_byte options don't have this problem.)
181
182 The handling of very low rates has changed slightly. If the computed rate
183 is less than the event's count (usually one) then this event is the first
184 after a long gap. In this case the rate is set to the same as this event's
185 count, so that the first message of a spam run is counted properly.
186
187 The major new feature is a mechanism for counting the rate of unique
188 events. The new per_addr option counts the number of different
189 recipients that someone has sent messages to in the last time period. It
190 behaves like per_rcpt if all the recipient addresses are different, but
191 duplicate recipient addresses do not increase the measured rate. Like
192 the /count= option this is a general mechanism, so the per_addr option
193 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
194 example, measure the rate that a client uses different sender addresses
195 with the options per_mail/unique=$sender_address. There are further
196 details in the main documentation.

746 Note to Michael Haardt: I had to rename some vars in sieve.c. They
747 were called 'true' and it seems that C99 defines that as a reserved

749 not include C99-style headers which use bools without triggering

769

PH
770PH/02 When an IPv6 address is converted to a string for single-key lookup
771 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
772 dots are used instead of colons so that keys in lsearch files need not
773 contain colons. This was done some time before quoting was made available
774 in lsearch files. However, iplsearch files do require colons in IPv6 keys
775 (notated using the quote facility) so as to distinguish them from IPv4
776 keys. This meant that lookups for IP addresses in host lists did not work
777 for iplsearch lookups.
778
779 This has been fixed by arranging for IPv6 addresses to be expressed with
780 colons if the lookup type is iplsearch. This is not incompatible, because
781 previously such lookups could never work.
782
783 The situation is now rather anomolous, since one *can* have colons in
784 ordinary lsearch keys. However, making the change in all cases is
785 incompatible and would probably break a number of configurations.

790MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
791 conversion specification without a maximum field width, thereby enabling
792 a rogue spamd server to cause a buffer overflow. While nobody in their
793 right mind would setup Exim to query an untrusted spamd server, an
794 attacker that gains access to a server running spamd could potentially
795 exploit this vulnerability to run arbitrary code as the Exim user.

800MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
801 a directory entry by the name of the lookup key. Previously, if a

803 Exim lacked permissions to read, a lookup for a key matching that

988PH/29 SMTP synchronization checks are implemented when a command is read -
989 there is a check that no more input is waiting when there shouldn't be

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

PH
1068 the response to the final '.' that terminates a message, but only in the
1069 case where the client has not sent further data following the '.'
1070 (unfortunately, this is allowed). However, in many cases there won't be
1071 any further data because there won't be any more messages to send. A call
1072 to select() can be used: if it shows that the input is "ready", there is
1073 either input waiting, or the socket has been closed. An attempt to read
1074 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1075 would have sent an OK response which the client would never have see.

1086PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1087 fixed by 4.65/MH/01 (is this a record?) are fixed:
1088
1089 (i) An empty string was always treated as zero by the numeric comparison
1090 operators. This behaviour has been restored.
1091
1092 (ii) It is documented that the numeric comparison operators always treat
1093 their arguments as decimal numbers. This was broken in that numbers
1094 starting with 0 were being interpreted as octal.
1095
1096 While fixing these problems I realized that there was another issue that
1097 hadn't been noticed. Values of message_size_limit (both the global option
1098 and the transport option) were treated as octal if they started with 0.
1099 The documentation was vague. These values are now always treated as
1100 decimal, and I will make that clear in the documentation.

PH
1144PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1145 callout verification, Exim cached a "reject" for the entire domain. This
1146 is correct for most verifications, but it is not correct for a recipient
1147 verification with use_sender or use_postmaster set, because in that case
1148 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1149 case of MAIL FROM:<> rejection from other early rejections (e.g.
1150 rejection of HELO). When verifying a recipient using a non-null MAIL
1151 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1152 Whatever the result of the callout, the value of the domain cache is
1153 left unchanged (for any other kind of callout, getting as far as trying
1154 RCPT means that the domain itself is ok).

1191 callout (which could be using a different interface). This has been
1192 changed to use the value of the helo_data option from the smtp transport
1193 instead - this is what is used when a message is actually being sent. If
1194 there is no remote transport (possible with a router that sets up host

14aa5a05 1197PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1198 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1199 (a) The code assumed that strncpy() returns a negative number on buffer
1200 overflow, which isn't the case. Replaced with Exim's string_format()
1201 function.
1202 (b) There were several signed/unsigned issues. I just did the minimum
1203 hacking in of casts. There is scope for a larger refactoring.
1204 (c) The code used strcasecmp() which is not a standard C function.
1205 Replaced with Exim's strcmpic() function.
1206 (d) The code set only $1; it now sets $auth1 as well.
1207 (e) A simple test gave the error "authentication client didn't specify
1208 service in request". It would seem that Dovecot has changed its
1209 interface. Fortunately there's a specification; I followed it and
1210 changed what the client sends and it appears to be working now.

e6f6568e
PH
1215PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1216 address A is aliased to B and C, where B exists and C does not. Without
1217 -v the output is "A verified" because verification stops after a
1218 successful redirection if more than one address is generated. However,
1219 with -v the child addresses are also verified. Exim was outputting "A
1220 failed to verify" and then showing the successful verification for C,
1221 with its parentage. It now outputs "B failed to verify", showing B's
1222 parentage before showing the successful verification of C.

PH
1224PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
1225 look up a TXT record in a specific list after matching in a combined
1226 list.
1227
322050c2
PH
1228PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1229 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1230 they consult the DNS. I had assumed they would set it the way they
1231 wanted; and indeed my experiments on Linux seem to show that in some
1232 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1233 To be on the safe side, however, I have now made the interface to
1234 host_find_byname() similar to host_find_bydns(), with an argument
1235 containing the DNS resolver options. The host_find_byname() function now
1236 sets these options at its start, just as host_find_bydns() does. The smtp
1237 transport options dns_qualify_single and dns_search_parents are passed to
1238 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1239 of host_find_byname() use the default settings of RES_DEFNAMES
1240 (qualify_single) but not RES_DNSRCH (search_parents).
1241
08955dd3
PH
1242PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1243 spool_read_header() do less string testing, by means of a preliminary
1244 switch on the second character of optional "-foo" lines. (This is
1245 overdue, caused by the large number of possibilities that now exist.
1246 Originally there were few.) While I was there, I also converted the
1247 str(n)cmp tests so they don't re-test the leading "-" and the first
1248 character, in the hope this might squeeze out yet more improvement.
1249

PH
1250PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1251 flag allowing group syntax was set by the header_syntax check but not
1252 turned off, possible causing trouble later; (2) The flag was not being
1253 set at all for the header_verify test, causing "group"-style headers to
1254 be rejected. I have now set it in this case, and also caused header_
1255 verify to ignore an empty address taken from a group. While doing this, I
1256 came across some other cases where the code for allowing group syntax
1257 while scanning a header line wasn't quite right (mostly, not resetting
1258 the flag correctly in the right place). These bugs could have caused
1259 trouble for malformed header lines. I hope it is now all correct.
1260
602e59e5
PH
1261PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1262 with the "reply" argument non-NULL. The code, however (which originally
1263 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1264 but it didn't always do it. This confused somebody who was copying the
1265 code for some other use. I have removed all the tests.
1266
411ef850
PH
1267PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1268 feature that was used to support insecure browsers during the U.S. crypto
1269 embargo. It requires special client support, and Exim is probably the
1270 only MTA that supported it -- and would never use it because real RSA is
1271 always available. This code has been removed, because it had the bad
1272 effect of slowing Exim down by computing (never used) parameters for the
1273 RSA_EXPORT functionality.
1274
7befa435
PH
1275PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1276 authenticator to fail if there's a tab character in the incoming data
1277 (there should never be unless someone is messing about, as it's supposed
1278 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1279 if the connection is using TLS or if the remote IP is the same as the
1280 local IP, and the "valid-client-cert option" if a client certificate has
1281 been verified.
1282
48da4259 1283PH/22 As suggested by Dennis Davis, added a server_condition option to *all*

1285 succeeds. (In the case of plaintext, it servers for both authentication
1286 and authorization.)

PH
1312
1313PH/30 Exim was sometimes attempting to deliver messages that had suffered
1314 address errors (4xx response to RCPT) over the same connection as other
1315 messages routed to the same hosts. Such deliveries are always "forced",
1316 so retry times are not inspected. This resulted in far too many retries
1317 for the affected addresses. The effect occurred only when there were more
1318 hosts than the hosts_max_try setting in the smtp transport when it had
1319 the 4xx errors. Those hosts that it had tried were not added to the list
1320 of hosts for which the message was waiting, so if all were tried, there
1321 was no problem. Two fixes have been applied:
1322
1323 (i) If there are any address or message errors in an SMTP delivery, none
1324 of the hosts (tried or untried) are now added to the list of hosts
1325 for which the message is waiting, so the message should not be a
1326 candidate for sending over the same connection that was used for a
1327 successful delivery of some other message. This seems entirely
1328 reasonable: after all the message is NOT "waiting for some host".
1329 This is so "obvious" that I'm not sure why it wasn't done
1330 previously. Hope I haven't missed anything, but it can't do any
1331 harm, as the worst effect is to miss an optimization.
1332
1333 (ii) If, despite (i), such a delivery is accidentally attempted, the
1334 routing retry time is respected, so at least it doesn't keep
1335 hammering the server.

PH
1350PH/35 The error "getsockname() failed: connection reset by peer" was being
1351 written to the panic log as well as the main log, but it isn't really
1352 panic-worthy as it just means the connection died rather early on. I have
1353 removed the panic log writing for the ECONNRESET error when getsockname()
1354 fails.
1355
48c7f9e2
PH
1356PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1357 runs only) independently of the message's sender address. This meant
1358 that, if the 4xx error was in fact related to the sender, a different
1359 message to the same recipient with a different sender could confuse
1360 things. In particualar, this can happen when sending to a greylisting
1361 server, but other circumstances could also provoke similar problems.
1362 I have changed the default so that the retry time for these errors is now
1363 based a combination of the sender and recipient addresses. This change
1364 can be overridden by setting address_retry_include_sender=false in the
1365 smtp transport.

1633PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
1634 "Deny" causes Exim to reject the incoming connection with a 554 error.
1635 Unfortunately, if there is a major crisis, such as a disk failure,
1636 tcp-wrappers gives "deny", whereas what one would like would be some
1637 kind of temporary error. A kludge has been added to help with this.
1638 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1639 554 error is used if errno is still zero or contains ENOENT (which occurs
1640 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1641 451 error is used.

1677PH/01 The code for finding all the local interface addresses on a FreeBSD
1678 system running IPv6 was broken. This may well have applied to all BSD
1679 systems, as well as to others that have similar system calls. The broken
1680 code found IPv4 interfaces correctly, but gave incorrect values for the
1681 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1682 that it would not match correctly against @[] and not recognize the IPv6
1683 addresses as local.

1726 autoreply, Exim could try to deliver to a non-existent relative file

1749 (a) Failures to set uid/gid, the current directory, or a process leader
1750 in a subprocess such as that created by queryprogram now generate
1751 suitable debugging ouput when -d is set.

1762 Instead, it always explicitly searches for A/AAAA records. This avoids
1763 major problems that occur when a DNS server includes only records of one
1764 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1765 fixed another bug: if SRV records were looked up and the corresponding
1766 address records were *not* found in the additional section, the port
1767 values from the SRV records were lost.

PH
1777PH/19 When calculating a retry time, Exim used to measure the "time since
1778 failure" by looking at the "first failed" field in the retry record. Now
1779 it does not use this if it is later than than the arrival time of the
1780 message. Instead it uses the arrival time. This makes for better
1781 behaviour in cases where some deliveries succeed, thus re-setting the
1782 "first failed" field. An example is a quota failure for a huge message
1783 when small messages continue to be delivered. Without this change, the
1784 "time since failure" will always be short, possible causing more frequent
1785 delivery attempts for the huge message than are intended.

PH
1882PH/42 The content-scanning code uses fopen() to create files in which to put
1883 message data. Previously it was not paying any attention to the mode of
1884 the files. Exim runs with umask(0) because the rest of the code creates
1885 files with open(), and sets the required mode explicitly. Thus, these
1886 files were ending up world-writeable. This was not a big issue, because,
1887 being within the spool directory, they were not world-accessible. I have
1888 created a function called modefopen, which takes an additional mode
1889 argument. It sets umask(777), creates the file, chmods it to the required
1890 mode, then resets the umask. All the relevant calls to fopen() in the

1928
1929 (i) Exim was not creating retry information for temporary errors given
1930 for individual recipients after the DATA command when the smtp transport
1931 was used in LMTP mode. This meant that they could be retried too
1932 frequently, and not timed out correctly.
1933
1934 (ii) Exim was setting the flag that allows error details to be returned
1935 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1936 recipients that were returned after the DATA command.
1937
1938PH/53 This is related to PH/52, but is more general: for any failing address,
1939 when detailed error information was permitted to be returned to the

2012PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2013 function verify_get_ident() calls ip_connect() to connect a socket, but
2014 if the "connect()" function timed out, ip_connect() used to close the
2015 socket. However, verify_get_ident() also closes the socket later, and in
2016 between Exim writes to the log, which may get opened at this point. When
2017 the socket was closed in ip_connect(), the log could get the same file
2018 descriptor number as the socket. This naturally causes chaos. The fix is
2019 not to close the socket in ip_connect(); the socket should be closed by
2020 the function that creates it. There was only one place in the code where
2021 this was missing, in the iplookup router, which I don't think anybody now
2022 uses, but I've fixed it anyway.

2045
2046 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2047 string.
2048
2049 (3) Reset the variables that are obtained from the first argument of
2050 ${prvscheck and used in the second argument before leaving the code,
2051 because their memory is reclaimed, so using them afterwards may do
2052 silly things.
2053
2054 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2055 one (it's much easier than Tom thought :-).
2056
2057 (5) Because of (4), we can now allow for the use of $prvscheck_result

2073 may be more than one such address. If so, they are comma-separated, like

2078PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2079 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2080 not being looked up in the rDNS to get a host name, Exim was showing the
2081 IP address twice in Received: lines, even though the IP addresses were
2082 identical. For example:
2083
2084 Received: from [1.2.3.4] (helo=[1.2.3.4])
2085
2086 However, if the real host name was known, it was omitting the HELO data
2087 if it matched the actual IP address. This has been tidied up so that it
2088 doesn't show the same IP address twice.

2119 in the messages that it generates (bounce messages and others, such as
2120 warnings). In the case of bounce messages for non-SMTP mesages, there was
2121 also a typo: it was using "Auto_submitted" (underscore instead of
2122 hyphen). Since every message generated by Exim is necessarily in response
2123 to another message, thes have all been changed to:
2124
2125 Auto-Submitted: auto-replied
2126
2127 in accordance with these statements in the RFC:
2128
2129 The auto-replied keyword:

2177PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated

2179 the IP address, check_host() was doing a simple string comparison with
2180 addresses acquired from the DNS when checking that the found name did
2181 have the original IP as one of its addresses. Since any found IPv6
2182 addresses are likely to be in abbreviated form, the comparison could
2183 fail. Luckily, there already exists a function for doing the comparison
2184 by converting both addresses to binary, so now that is used instead of
2185 the text comparison.

2483 with the definition in sysexits.h (which is #included earlier).
2484 Fortunately, Exim does not actually use EX_OK. The code used to try to
2485 preserve the sysexits.h value, by assumimg that macro definitions were
2486 scanned for macro replacements. I have been disabused of this notion,

2492 This seems wrong - if the receiver was accepting one byte at a time it
2493 would take for ever. The timeout is now adjusted when this happens. It
2494 doesn't have to be particularly precise.

2571 suddenly stopped working when I started to use syslog. The patch checks

2703PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2704 that changes the way the GnuTLS parameters are stored in the cache file.
2705 The new format can be generated externally. For backward compatibility,
2706 if the data in the cache doesn't make sense, Exim assumes it has read an
2707 old-format file, and it generates new data and writes a new file. This
2708 means that you can't go back to an older release without removing the
2709 file.
2710
2711PH/03 A redirect router that has both "unseen" and "one_time" set does not
2712 work if there are any delivery delays because "one_time" forces the
2713 parent to be marked "delivered", so its unseen clone is never tried
2714 again. For this reason, Exim now forbids the simultaneous setting of
2715 these two options.
2716
2717PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2718 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2719 entry if you want to know the details. The fix, however, neglected to
2720 consider the case when local delivery batching is involved. The test for
2721 "previously delivered" was not happening when checking to see if an
2722 address could be batched with a previous (undelivered) one; under
2723 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2724 address.

2729PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2730 header_syntax) but Exim was just ignoring anything given after a slash.
2731 In particular, this caused confusion with an attempt to use "verify =
2732 reverse_host_lookup/defer_ok". An error is now given when options are
2733 supplied for verify items that do not have them. (Maybe reverse_host_
2734 lookup should have a defer_ok option, but that's a different point.)

2736PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2786PH/19 When an Exim process that is running as root has to create an Exim log
2787 file, it does so in a subprocess that runs as exim:exim so as to get the
2788 ownership right at creation (otherwise, other Exim processes might see
2789 the file with the wrong ownership). There was no test for failure of this
2790 fork() call, which would lead to the process getting stuck as it waited
2791 for a non-existent subprocess. Forks do occasionally fail when resources
2792 run out. I reviewed all the other calls to fork(); they all seem to check
2793 for failure.

2795PH/20 When checking for unexpected SMTP input at connect time (before writing

2797 from the read() function. If the client had disconnected by this time,
2798 the result was a log entry for a synchronization error with an empty
2799 string after "input=" when read() returned zero. If read() returned -1
2800 (an event I could not check), uninitialized data bytes were printed.

PH
2812PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2813 hadn't been configured. The fix is from Juergen Kreileder, who
2814 understands it better than I do:
2815
2816 "Here's what I see happening with three configured cyrus_sasl
2817 authenticators configured (plain, login, cram-md5):
2818
2819 On startup auth_cyrus_sasl_init() gets called for each of these.
2820 This means three calls to sasl_listmech() without a specified mech_list.
2821 => SASL tests which mechs of all available mechs actually work
2822 => three warnings about OTP not working
2823 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2824
2825 With the patch, sasl_listmech() also gets called three times. But now
2826 SASL's mech_list option is set to the server_mech specified in the the
2827 authenticator. Or in other words, the answer from sasl_listmech()
2828 gets limited to just the mech you're testing for (which is different
2829 for each call.)
2830 => the return list contains just 'plain' or 'login', 'cram-md5' or
2831 nothing depending on the value of ob->server_mech.
2832
2833 I've just tested the patch: Authentication still works fine,
2834 unavailable mechs specified in the exim configuration are still
2835 caught, and the auth.log warnings about OTP are gone."

PH
2899PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2900 the grounds that routing the same address twice would always produce the
2901 same answer. This might have been true once, but it is certainly no
2902 longer true now. Routing a child address may depend on the previous
2903 routing that produced that child. Some complicated redirection strategies
2904 went wrong when messages had multiple recipients, and made Exim's
2905 behaviour dependent on the order in which the addresses were given.
2906
2907 I have moved the duplicate checking until after the routing is complete.
2908 Exim scans the addresses that are assigned to local and remote
2909 transports, and removes any duplicates. This means that more work will be
2910 done, as duplicates will always all be routed, but duplicates are
2911 presumably rare, so I don't expect this is of any significance.
2912
2913 For deliveries to pipes, files, and autoreplies, the duplicate checking
2914 still happens during the routing process, since they are not going to be
2915 routed further.

2960 consistency with the overall process timeout, these timeouts are now
2961 treated as errors, giving rise to delivery failures by default. However,
2962 there is now a new Boolean option for the pipe transport called

2974A note about Exim versions 4.44 and 4.50
2975----------------------------------------
2976
2977Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2978changes of various kinds. As a consequence, a big documentation update was
2979needed. This delayed the release for rather longer than seemed good, especially
2980in the light of a couple of (minor) security issues. Therefore, the changes
2981that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2982release. So 4.44 and 4.50 are in effect two different branches that both start
2983from 4.43.
2984
2985I have left the 4.50 change log unchanged; it contains all the changes since
29864.43. The change log for 4.44 is below; many of its items are identical to
2987those for 4.50. This seems to be the most sensible way to preserve the
2988historical information.

3008 was being done only for the command run by the queryprogram router. It is
3009 now done for all such subprocesses. The other cases are: ${run, transport
3010 filters, and the commands run by the lmtp and pipe transports.

3015 descriptors. Exim was using setrlimit() to set 1000 as a large value
3016 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3017 systems. I've change it so that if it can't get 1000, it tries for 256.

306723. When checking ignore_target_hosts for an ipliteral router, no host name was
3068 being passed; this would have caused $sender_host_name to have been used if

309129. In an address list, if the pattern was not a regular expression, an empty
3092 subject address (from a bounce message) matched only if the pattern was an
3093 empty string. Non-empty patterns were not even tested. This was the wrong
3094 because it is perfectly reasonable to use an empty address as part of a
3095 database query. An empty address is now tested by patterns that are
3096 lookups. However, all the other forms of pattern expect the subject to
3097 contain a local part and a domain, and therefore, for them, an empty
3098 address still always fails if the pattern is not itself empty.

PH
310932. The RFC2047 encoding function was originally intended for short strings
3110 such as real names; it was not keeping to the 75-character limit for
3111 encoded words that the RFC imposes. It now respects the limit, and
3112 generates multiple encoded words if necessary. To be on the safe side, I
3113 have increased the buffer size for the ${rfc2047: expansion operator from
3114 1024 to 2048 bytes.
3115

PH
311633. It is now permitted to omit both strings after an "if" condition; if the
3117 condition is true, the result is "true". As before, when the second string
3118 is omitted, a false condition yields an empty string. This makes it less
3119 cumbersome to write custom ACL and router conditions.
3120

312936. The table in the code that translates DNS record types into text (T_A to
3130 "A" for instance) was missing entries for NS and CNAME. It is just possible
3131 that this could have caused confusion if both these types were looked up
3132 for the same domain, because the text type is used as part of Exim's
3133 per-process caching. But the chance of anyone hitting this buglet seems
3134 very small.

316643. Did the same fix as 41 above for OpenSSL, which had the same infelicity.

PH
316844. The "Exiscan patch" is now merged into the mainline Exim source.
3169
317045. Sometimes the final signoff response after QUIT could fail to get
3171 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3172 < 0 before doing a fflush(). This bug looks as though it goes back to the
3173 introduction of TLS in release 3.20, but "sometimes" must have been rare
3174 because the tests only now provoked it.
3175

PH
317646. Reset the locale to "C" after calling embedded Perl, in case it was changed
3177 (this can affect the format of dates).

PH
317947. exim_tidydb, when checking for the continued existence of a message for
3180 which it has found a message-specific retry record, was not finding
3181 messages that were in split spool directories. Consequently, it was
3182 deleting retry records that should have stayed in existence.

PH
318448. Steve fixed some bugs in eximstats.
3185
318649. The SPA authentication driver was not abandoning authentication and moving
3187 on to the next authenticator when an expansion was forced to fail,
3188 contradicting the general specification for all authenticators. Instead it
3189 was generating a temporary error. It now behaves as specified.
3190

PH
319150. The default ordering of permitted cipher suites for GnuTLS was pessimal
3192 (the order specifies the preference for clients). The order is now AES256,
3193 AES128, 3DES, ARCFOUR128.
3194

PH
319551. Small patch to Sieve code - explicitly set From: when generating an
3196 autoreply.
3197
1c5466b9
PH
319852. Exim crashed if a remote delivery caused a very long error message to be
3199 recorded - for instance if somebody sent an entire SpamAssassin report back
3200 as a large number of 550 error lines. This bug was coincidentally fixed by
3201 increasing the size of one of Exim's internal buffers (big_buffer) that
3202 happened as part of the Exiscan merge. However, to be on the safe side, I
3203 have made the code more robust (and fixed the comments that describe what
3204 is going on).
3205
55ee9ee3
PH
320653. Now that there can be additional text after "Completed" in log lines (if
3207 the queue_time_overall log selector is set), a one-byte patch to exigrep
3208 was needed to allow it to recognize "Completed" as not the last thing in
3209 the line.
3210

PH
321154. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3212 patch that reportedly fixes this has been added. I am not expert enough to
3213 create a test for it. This is what the patch creator wrote:
3214
3215 "I found a little strange behaviour of ldap code when working with
3216 Windows 2003 AD Domain, where users was placed in more than one
3217 Organization Units. When I tried to give exim partial DN, the exit code
3218 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3219 But simultaneously result of request was absolutely normal ldap result,
3220 so I produce this patch..."
3221
3295e65b
PH
3222 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3223 REFERENCE, so I have modified the code to exclude the patch when that macro
3224 is not defined.
3225
7102e136
PH
322655. Some experimental protocols are using DNS PTR records for new purposes. The
3227 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3228 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3229 leaves it alone. Component reversal etc. now happens only for IP addresses.

323457. Double the size of the debug message buffer (to 2048) so that more of very
3235 long debug lines gets shown.
3236
18ce445d
PH
323758. The exicyclog utility now does better if the number of log files to keep
3238 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
3239

PH
324059. Two changes related to the smtp_active_hostname option:
3241
3242 (1) $smtp_active_hostname is now available as a variable.
3243 (2) The default for smtp_banner uses $smtp_active_hostname instead
3244 of $primary_hostname.
3245
b975ba52
PH
324660. The host_aton() function is supposed to be passed a string that is known
3247 to be a valid IP address. However, in the case of IPv6 addresses, it was
3248 not checking this. This is a hostage to fortune. Exim now panics and dies
3249 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3250 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3251 components; fortuitously, this particular loophole had already been fixed
3252 by change 4.50/55 above.
3253
3254 If there are any other similar loopholes, the new check in host_aton()
3255 itself should stop them being exploited. The report I received stated that
3256 data on the command line could provoke the exploit when Exim was running as
3257 exim, but did not say which command line option was involved. All I could
3258 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3259 running as the user.

326261. There was a buffer overflow vulnerability in the SPA authentication code
3263 (which came originally from the Samba project). I have added a test to the
3264 spa_base64_to_bits() function which I hope fixes it.

PH
327063. The daemon start-up calls getloadavg() while still root for those OS that
3271 need the first call to be done as root, but it missed one case: when
3272 deliver_queue_load_max is set with deliver_drop_privilege. This is
3273 necessary for the benefit of the queue runner, because there is no re-exec
3274 when deliver_drop_privilege is set.
3275
86b8287f
PH
327664. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3277 This has been fixed.
3278
60dc5e56
PH
327965. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3280 was in use, was not putting the data itself into the right store pool;
3281 consequently, it could be overwritten for a subsequent message in the same
3282 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3283 the caching.)
3284

PH
328566. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3286
a5a28604
PH
328767. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3288 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3289 the function were treating the return as a boolean value, which happened to
3290 work because 0=false and not-0=true, but is not correct code.
3291
7e634d24
PH
329268. The host_aton() function was not handling scoped IPv6 addresses (those
3293 with, for example, "%eth0" on the end) correctly.
3294
3e11c26b
PH
329569. Fixed some compiler warnings in acl.c for the bitmaps specified with
3296 negated items (that is, ~something) in unsigned ints. Some compilers
3297 apparently mutter when there is no cast.
3298
6729cf78
PH
329970. If an address verification called from an ACL failed, and did not produce a
3300 user-specific message (i.e. there was only a "system" message), nothing was
3301 put in $acl_verify_message. In this situation, it now puts the system
3302 message there.
3303
00f00ca5
PH
330471. Change 4.23/11 added synchronization checking at the start of an SMTP
3305 session; change 4.31/43 added the unwanted input to the log line - except
3306 that it did not do this in the start of session case. It now does.
3307
c9bdd01c
PH
330872. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3309 This is wrong and can cause the other end to generate a synchronization
3310 error if it is another Exim or anything else that does the synchronization
3311 check. A QUIT command is no longer sent after a timeout.
3312

PH
331373. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3314 during host lookups.
3315

PH
331674. The defer_ok option of callout verification was not working if it was used
3317 when verifying addresses in header lines, that is, for this case:
3318
3319 verify = header_sender/callout=defer_ok
3320
76a2d7ba
PH
332175. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3322 those file descriptors could be used for SMTP connections. If anything
3323 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3324 could be sent to the SMTP client, causing chaos. The daemon now opens
3325 stdin, stdout, and stderr to /dev/null when it puts itself into the
3326 background.
3327
332876. Arrange for output from Perl's "warn" command to be written to Exim's main
3329 log by default. The user can override this with suitable Perl magic.
3330
04f7d5b9
PH
333177. The use of log_message on a "discard" ACL verb, which is supposed to add to
3332 the log message when discard triggers, was not working for the DATA ACL or
3333 for the non-SMTP ACL.
3334
bc60667e
PH
333578. Error message wording change in sieve.c.
3336
bb6e88ff
PH
333779. If smtp_accept_max_per_host was set, the number of connections could be
3338 restricted to fewer than expected, because the daemon was trying to set up
3339 a new connection before checking whether the processes handling previous
3340 connections had finished. The check for completed processes is now done
3341 earlier. On busy systems, this bug wouldn't be noticed because something
3342 else would have woken the daemon, and it would have reaped the completed
3343 process earlier.
3344
1e70f85b
PH
334580. If a message was submitted locally by a user whose login name contained one
3346 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3347 It caused a spool format error. I have fixed the spool reading code. A
3348 related problem was that the "from" clause in the Received: line became
3349 illegal because of the space(s). It is now covered by ${quote_local_part.
3350

3352 tables).

3366See the note above about the 4.44 and 4.50 releases.
3367----------------------------------------------------
3368
3369
3370Exim version 4.44
3371-----------------
3372
3373 1. Change 4.43/35 introduced a bug that caused file counts to be
3374 incorrectly computed when quota_filecount was set in an appendfile
3375 transport
3376
3377 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3378 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3379 place.
3380
3381 3. Give more explanation in the error message when the command for a transport
3382 filter fails to execute.
3383
3384 4. There are several places where Exim runs a non-Exim command in a
3385 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3386 was being done only for the command run by the queryprogram router. It is
3387 now done for all such subprocesses. The other cases are: ${run, transport
3388 filters, and the commands run by the lmtp and pipe transports.
3389
3390 5. Some older OS have a limit of 256 on the maximum number of file
3391 descriptors. Exim was using setrlimit() to set 1000 as a large value
3392 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3393 systems. I've change it so that if it can't get 1000, it tries for 256.
3394
3395 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3396 was an oversight, and furthermore, ever since the addition of extra
3397 controls (e.g. 4.43/32), the checks on when to allow different forms of
3398 "control" were broken. There should now be diagnosti
