104
17c76198
PP
105PP/25 Revamped GnuTLS support, passing tls_require_ciphers to
106 gnutls_priority_init, ignoring Exim options gnutls_require_kx,
107 gnutls_require_mac & gnutls_require_protocols (no longer supported).
108 Added SNI support via GnuTLS too.

128 when unlink() failed. See also change 4.74-TF/03.
129
921b12ca
TF
130TF/03 Make the exiwhat support code safe for signals. Previously Exim might
131 lock up or crash if it happened to be inside a call to libc when it
132 got a SIGUSR1 from exiwhat.
133
134 The SIGUSR1 handler appends the current process status to the process
135 log which is later printed by exiwhat. It used to use the general
136 purpose logging code to do this, but several functions it calls are
137 not safe for signals.
138
139 The new output code in the SIGUSR1 handler is specific to the process
140 log, and simple enough that it's easy to inspect for signal safety.
141 Removing some special cases also simplifies the general logging code.
142 Removing the spurious timestamps from the process log simplifies
143 exiwhat.
144
c99ce5c9
TF
145TF/04 Improved ratelimit ACL condition.
146
147 The /noupdate option has been deprecated in favour of /readonly which
148 has clearer semantics. The /leaky, /strict, and /readonly update modes
149 are mutually exclusive. The update mode is no longer included in the
150 database key; it just determines when the database is updated. (This
151 means that when you upgrde Exim will forget old rate measurements.)
152
153 Exim now checks that the per_* options are used with an update mode that
154 makes sense for the current ACL. For example, when Exim is processing a
155 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
156 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
157 must specify per_mail/readonly. If you omit the update mode it defaults to
158 /leaky where that makes sense (as before) or /readonly where required.
159
160 The /noupdate option is now undocumented but still supported for
161 backwards compatibility. It is equivalent to /readonly except that in
162 ACLs where /readonly is required you may specify /leaky/noupdate or
163 /strict/noupdate which are treated the same as /readonly.
164
165 A useful new feature is the /count= option. This is a generalization
166 of the per_byte option, so that you can measure the throughput of other
167 aggregate values. For example, the per_byte option is now equivalent
168 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
169
170 The per_rcpt option has been generalized using the /count= mechanism
171 (though it's more complicated than the per_byte equivalence). When it is
172 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
173 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
174 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
175 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
176 Note that using per_rcpt with a non-readonly update mode in more than
177 one ACL will cause the recipients to be double-counted. (The per_mail
178 and per_byte options don't have this problem.)
179
180 The handling of very low rates has changed slightly. If the computed rate
181 is less than the event's count (usually one) then this event is the first
182 after a long gap. In this case the rate is set to the same as this event's
183 count, so that the first message of a spam run is counted properly.
184
185 The major new feature is a mechanism for counting the rate of unique
186 events. The new per_addr option counts the number of different
187 recipients that someone has sent messages to in the last time period. It
188 behaves like per_rcpt if all the recipient addresses are different, but
189 duplicate recipient addresses do not increase the measured rate. Like
190 the /count= option this is a general mechanism, so the per_addr option
191 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
192 example, measure the rate that a client uses different sender addresses
193 with the options per_mail/unique=$sender_address. There are further
194 details in the main documentation.

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

766PH/01 Another patch from the Sieve maintainer.
767
6a3bceb1
PH
768PH/02 When an IPv6 address is converted to a string for single-key lookup
769 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
770 dots are used instead of colons so that keys in lsearch files need not
771 contain colons. This was done some time before quoting was made available
772 in lsearch files. However, iplsearch files do require colons in IPv6 keys
773 (notated using the quote facility) so as to distinguish them from IPv4
774 keys. This meant that lookups for IP addresses in host lists did not work
775 for iplsearch lookups.
776
777 This has been fixed by arranging for IPv6 addresses to be expressed with
778 colons if the lookup type is iplsearch. This is not incompatible, because
779 previously such lookups could never work.
780
781 The situation is now rather anomolous, since one *can* have colons in
782 ordinary lsearch keys. However, making the change in all cases is
783 incompatible and would probably break a number of configurations.

788MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
789 conversion specification without a maximum field width, thereby enabling
790 a rogue spamd server to cause a buffer overflow. While nobody in their
791 right mind would setup Exim to query an untrusted spamd server, an
792 attacker that gains access to a server running spamd could potentially
793 exploit this vulnerability to run arbitrary code as the Exim user.

798MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for

986PH/29 SMTP synchronization checks are implemented when a command is read -
987 there is a check that no more input is waiting when there shouldn't be

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

PH
1066 the response to the final '.' that terminates a message, but only in the
1067 case where the client has not sent further data following the '.'
1068 (unfortunately, this is allowed). However, in many cases there won't be
1069 any further data because there won't be any more messages to send. A call
1070 to select() can be used: if it shows that the input is "ready", there is
1071 either input waiting, or the socket has been closed. An attempt to read
1072 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1073 would have sent an OK response which the client would never have see.

1084PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1085 fixed by 4.65/MH/01 (is this a record?) are fixed:
1086
1087 (i) An empty string was always treated as zero by the numeric comparison
1088 operators. This behaviour has been restored.
1089
1090 (ii) It is documented that the numeric comparison operators always treat
1091 their arguments as decimal numbers. This was broken in that numbers
1092 starting with 0 were being interpreted as octal.
1093
1094 While fixing these problems I realized that there was another issue that
1095 hadn't been noticed. Values of message_size_limit (both the global option
1096 and the transport option) were treated as octal if they started with 0.
1097 The documentation was vague. These values are now always treated as
1098 decimal, and I will make that clear in the documentation.

1115 large number of recipients for a single message is ridiculous

2b1c6e3a
PH
1142PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1143 callout verification, Exim cached a "reject" for the entire domain. This
1144 is correct for most verifications, but it is not correct for a recipient
1145 verification with use_sender or use_postmaster set, because in that case
1146 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1147 case of MAIL FROM:<> rejection from other early rejections (e.g.
1148 rejection of HELO). When verifying a recipient using a non-null MAIL
1149 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1150 Whatever the result of the callout, the value of the domain cache is
1151 left unchanged (for any other kind of callout, getting as far as trying
1152 RCPT means that the domain itself is ok).

1189 callout (which could be using a different interface). This has been
1190 changed to use the value of the helo_data option from the smtp transport
1191 instead - this is what is used when a message is actually being sent. If
1192 there is no remote transport (possible with a router that sets up host

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

e6f6568e
PH
1213PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1214 address A is aliased to B and C, where B exists and C does not. Without
1215 -v the output is "A verified" because verification stops after a
1216 successful redirection if more than one address is generated. However,
1217 with -v the child addresses are also verified. Exim was outputting "A
1218 failed to verify" and then showing the successful verification for C,
1219 with its parentage. It now outputs "B failed to verify", showing B's
1220 parentage before showing the successful verification of C.

PH
1222PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
1223 look up a TXT record in a specific list after matching in a combined
1224 list.
1225
322050c2
PH
1226PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1227 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1228 they consult the DNS. I had assumed they would set it the way they
1229 wanted; and indeed my experiments on Linux seem to show that in some
1230 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1231 To be on the safe side, however, I have now made the interface to
1232 host_find_byname() similar to host_find_bydns(), with an argument
1233 containing the DNS resolver options. The host_find_byname() function now
1234 sets these options at its start, just as host_find_bydns() does. The smtp
1235 transport options dns_qualify_single and dns_search_parents are passed to
1236 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1237 of host_find_byname() use the default settings of RES_DEFNAMES
1238 (qualify_single) but not RES_DNSRCH (search_parents).
1239
08955dd3
PH
1240PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1241 spool_read_header() do less string testing, by means of a preliminary
1242 switch on the second character of optional "-foo" lines. (This is
1243 overdue, caused by the large number of possibilities that now exist.
1244 Originally there were few.) While I was there, I also converted the
1245 str(n)cmp tests so they don't re-test the leading "-" and the first
1246 character, in the hope this might squeeze out yet more improvement.
1247
1eccaa59
PH
1248PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1249 flag allowing group syntax was set by the header_syntax check but not
1250 turned off, possible causing trouble later; (2) The flag was not being
1251 set at all for the header_verify test, causing "group"-style headers to
1252 be rejected. I have now set it in this case, and also caused header_
1253 verify to ignore an empty address taken from a group. While doing this, I
1254 came across some other cases where the code for allowing group syntax
1255 while scanning a header line wasn't quite right (mostly, not resetting
1256 the flag correctly in the right place). These bugs could have caused
1257 trouble for malformed header lines. I hope it is now all correct.
1258
602e59e5
PH
1259PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1260 with the "reply" argument non-NULL. The code, however (which originally
1261 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1262 but it didn't always do it. This confused somebody who was copying the
1263 code for some other use. I have removed all the tests.
1264
411ef850
PH
1265PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1266 feature that was used to support insecure browsers during the U.S. crypto
1267 embargo. It requires special client support, and Exim is probably the
1268 only MTA that supported it -- and would never use it because real RSA is
1269 always available. This code has been removed, because it had the bad
1270 effect of slowing Exim down by computing (never used) parameters for the
1271 RSA_EXPORT functionality.
1272
7befa435
PH
1273PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1274 authenticator to fail if there's a tab character in the incoming data
1275 (there should never be unless someone is messing about, as it's supposed
1276 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1277 if the connection is using TLS or if the remote IP is the same as the
1278 local IP, and the "valid-client-cert option" if a client certificate has
1279 been verified.
1280
48da4259 1281PH/22 As suggested by Dennis Davis, added a server_condition option to *all*

1282 authenticators. This can be used for authorization after authentication
1283 succeeds. (In the case of plaintext, it servers for both authentication
1284 and authorization.)

PH
1310
1311PH/30 Exim was sometimes attempting to deliver messages that had suffered
1312 address errors (4xx response to RCPT) over the same connection as other
1313 messages routed to the same hosts. Such deliveries are always "forced",
1314 so retry times are not inspected. This resulted in far too many retries
1315 for the affected addresses. The effect occurred only when there were more
1316 hosts than the hosts_max_try setting in the smtp transport when it had
1317 the 4xx errors. Those hosts that it had tried were not added to the list
1318 of hosts for which the message was waiting, so if all were tried, there
1319 was no problem. Two fixes have been applied:
1320
1321 (i) If there are any address or message errors in an SMTP delivery, none
1322 of the hosts (tried or untried) are now added to the list of hosts
1323 for which the message is waiting, so the message should not be a
1324 candidate for sending over the same connection that was used for a
1325 successful delivery of some other message. This seems entirely
1326 reasonable: after all the message is NOT "waiting for some host".
1327 This is so "obvious" that I'm not sure why it wasn't done
1328 previously. Hope I haven't missed anything, but it can't do any
1329 harm, as the worst effect is to miss an optimization.
1330
1331 (ii) If, despite (i), such a delivery is accidentally attempted, the
1332 routing retry time is respected, so at least it doesn't keep
1333 hammering the server.

1344PH/34 The spec says: "With one important exception, whenever a domain list is

520de300
PH
1348PH/35 The error "getsockname() failed: connection reset by peer" was being
1349 written to the panic log as well as the main log, but it isn't really
1350 panic-worthy as it just means the connection died rather early on. I have
1351 removed the panic log writing for the ECONNRESET error when getsockname()
1352 fails.
1353
48c7f9e2
PH
1354PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1355 runs only) independently of the message's sender address. This meant
1356 that, if the 4xx error was in fact related to the sender, a different
1357 message to the same recipient with a different sender could confuse
1358 things. In particualar, this can happen when sending to a greylisting
1359 server, but other circumstances could also provoke similar problems.
1360 I have changed the default so that the retry time for these errors is now
1361 based a combination of the sender and recipient addresses. This change
1362 can be overridden by setting address_retry_include_sender=false in the
1363 smtp transport.
1364

PH
1365PH/37 For LMTP over TCP/IP (the smtp transport), error responses from the

1368 same for both kinds of LMTP.

1631PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
1632 "Deny" causes Exim to reject the incoming connection with a 554 error.
1633 Unfortunately, if there is a major crisis, such as a disk failure,
1634 tcp-wrappers gives "deny", whereas what one would like would be some
1635 kind of temporary error. A kludge has been added to help with this.
1636 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1637 554 error is used if errno is still zero or contains ENOENT (which occurs
1638 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1639 451 error is used.

1675PH/01 The code for finding all the local interface addresses on a FreeBSD
1676 system running IPv6 was broken. This may well have applied to all BSD
1677 systems, as well as to others that have similar system calls. The broken
1678 code found IPv4 interfaces correctly, but gave incorrect values for the
1679 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1680 that it would not match correctly against @[] and not recognize the IPv6
1681 addresses as local.

1724 autoreply, Exim could try to deliver to a non-existent relative file

1747 (a) Failures to set uid/gid, the current directory, or a process leader
1748 in a subprocess such as that created by queryprogram now generate
1749 suitable debugging ouput when -d is set.

1760 Instead, it always explicitly searches for A/AAAA records. This avoids
1761 major problems that occur when a DNS server includes only records of one
1762 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1763 fixed another bug: if SRV records were looked up and the corresponding
1764 address records were *not* found in the additional section, the port
1765 values from the SRV records were lost.

PH
1775PH/19 When calculating a retry time, Exim used to measure the "time since
1776 failure" by looking at the "first failed" field in the retry record. Now
1777 it does not use this if it is later than than the arrival time of the
1778 message. Instead it uses the arrival time. This makes for better
1779 behaviour in cases where some deliveries succeed, thus re-setting the
1780 "first failed" field. An example is a quota failure for a huge message
1781 when small messages continue to be delivered. Without this change, the
1782 "time since failure" will always be short, possible causing more frequent
1783 delivery attempts for the huge message than are intended.

PH
1880PH/42 The content-scanning code uses fopen() to create files in which to put
1881 message data. Previously it was not paying any attention to the mode of
1882 the files. Exim runs with umask(0) because the rest of the code creates
1883 files with open(), and sets the required mode explicitly. Thus, these
1884 files were ending up world-writeable. This was not a big issue, because,
1885 being within the spool directory, they were not world-accessible. I have
1886 created a function called modefopen, which takes an additional mode
1887 argument. It sets umask(777), creates the file, chmods it to the required
1888 mode, then resets the umask. All the relevant calls to fopen() in the

1926
1927 (i) Exim was not creating retry information for temporary errors given

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

2010PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2011 function verify_get_ident() calls ip_connect() to connect a socket, but
2012 if the "connect()" function timed out, ip_connect() used to close the
2013 socket. However, verify_get_ident() also closes the socket later, and in
2014 between Exim writes to the log, which may get opened at this point. When
2015 the socket was closed in ip_connect(), the log could get the same file
2016 descriptor number as the socket. This naturally causes chaos. The fix is
2017 not to close the socket in ip_connect(); the socket should be closed by
2018 the function that creates it. There was only one place in the code where
2019 this was missing, in the iplookup router, which I don't think anybody now
2020 uses, but I've fixed it anyway.

2043
2044 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2045 string.
2046
2047 (3) Reset the variables that are obtained from the first argument of
2048 ${prvscheck and used in the second argument before leaving the code,
2049 because their memory is reclaimed, so using them afterwards may do
2050 silly things.
2051
2052 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2053 one (it's much easier than Tom thought :-).
2054

2076PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2077 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2078 not being looked up in the rDNS to get a host name, Exim was showing the
2079 IP address twice in Received: lines, even though the IP addresses were
2080 identical. For example:
2081
2082 Received: from [1.2.3.4] (helo=[1.2.3.4])
2083
2084 However, if the real host name was known, it was omitting the HELO data
2085 if it matched the actual IP address. This has been tidied up so that it
2086 doesn't show the same IP address twice.

2117 in the messages that it generates (bounce messages and others, such as
2118 warnings). In the case of bounce messages for non-SMTP mesages, there was
2119 also a typo: it was using "Auto_submitted" (underscore instead of
2120 hyphen). Since every message generated by Exim is necessarily in response
2121 to another message, thes have all been changed to:
2122
2123 Auto-Submitted: auto-replied
2124
2125 in accordance with these statements in the RFC:
2126
2127 The auto-replied keyword:

2175PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated

2177 the IP address, check_host() was doing a simple string comparison with
2178 addresses acquired from the DNS when checking that the found name did
2179 have the original IP as one of its addresses. Since any found IPv6
2180 addresses are likely to be in abbreviated form, the comparison could
2181 fail. Luckily, there already exists a function for doing the comparison
2182 by converting both addresses to binary, so now that is used instead of
2183 the text comparison.

2481 with the definition in sysexits.h (which is #included earlier).
2482 Fortunately, Exim does not actually use EX_OK. The code used to try to
2483 preserve the sysexits.h value, by assumimg that macro definitions were
2484 scanned for macro replacements. I have been disabused of this notion,

2492 doesn't have to be particularly precise.

2569 suddenly stopped working when I started to use syslog. The patch checks

2701PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2702 that changes the way the GnuTLS parameters are stored in the cache file.
2703 The new format can be generated externally. For backward compatibility,
2704 if the data in the cache doesn't make sense, Exim assumes it has read an
2705 old-format file, and it generates new data and writes a new file. This
2706 means that you can't go back to an older release without removing the
2707 file.
2708
2709PH/03 A redirect router that has both "unseen" and "one_time" set does not
2710 work if there are any delivery delays because "one_time" forces the
2711 parent to be marked "delivered", so its unseen clone is never tried
2712 again. For this reason, Exim now forbids the simultaneous setting of
2713 these two options.
2714
2715PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2716 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2717 entry if you want to know the details. The fix, however, neglected to
2718 consider the case when local delivery batching is involved. The test for
2719 "previously delivered" was not happening when checking to see if an
2720 address could be batched with a previous (undelivered) one; under
2721 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2722 address.

PH
2723
2724PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2727PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2728 header_syntax) but Exim was just ignoring anything given after a slash.
2729 In particular, this caused confusion with an attempt to use "verify =
2730 reverse_host_lookup/defer_ok". An error is now given when options are
2731 supplied for verify items that do not have them. (Maybe reverse_host_
2732 lookup should have a defer_ok option, but that's a different point.)
2733
2734PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2784PH/19 When an Exim process that is running as root has to create an Exim log
2785 file, it does so in a subprocess that runs as exim:exim so as to get the
2786 ownership right at creation (otherwise, other Exim processes might see
2787 the file with the wrong ownership). There was no test for failure of this
2788 fork() call, which would lead to the process getting stuck as it waited
2789 for a non-existent subprocess. Forks do occasionally fail when resources
2790 run out. I reviewed all the other calls to fork(); they all seem to check
2791 for failure.

2793PH/20 When checking for unexpected SMTP input at connect time (before writing

2795 from the read() function. If the client had disconnected by this time,
2796 the result was a log entry for a synchronization error with an empty
2797 string after "input=" when read() returned zero. If read() returned -1
2798 (an event I could not check), uninitialized data bytes were printed.

PH
2810PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2811 hadn't been configured. The fix is from Juergen Kreileder, who
2812 understands it better than I do:
2813
2814 "Here's what I see happening with three configured cyrus_sasl
2815 authenticators configured (plain, login, cram-md5):
2816
2817 On startup auth_cyrus_sasl_init() gets called for each of these.
2818 This means three calls to sasl_listmech() without a specified mech_list.
2819 => SASL tests which mechs of all available mechs actually work
2820 => three warnings about OTP not working
2821 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2822
2823 With the patch, sasl_listmech() also gets called three times. But now
2824 SASL's mech_list option is set to the server_mech specified in the the
2825 authenticator. Or in other words, the answer from sasl_listmech()
2826 gets limited to just the mech you're testing for (which is different
2827 for each call.)
2828 => the return list contains just 'plain' or 'login', 'cram-md5' or
2829 nothing depending on the value of ob->server_mech.
2830
2831 I've just tested the patch: Authentication still works fine,
2832 unavailable mechs specified in the exim configuration are still
2833 caught, and the auth.log warnings about OTP are gone."

PH
2897PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2898 the grounds that routing the same address twice would always produce the
2899 same answer. This might have been true once, but it is certainly no
2900 longer true now. Routing a child address may depend on the previous
2901 routing that produced that child. Some complicated redirection strategies
2902 went wrong when messages had multiple recipients, and made Exim's
2903 behaviour dependent on the order in which the addresses were given.
2904
2905 I have moved the duplicate checking until after the routing is complete.
2906 Exim scans the addresses that are assigned to local and remote
2907 transports, and removes any duplicates. This means that more work will be
2908 done, as duplicates will always all be routed, but duplicates are
2909 presumably rare, so I don't expect this is of any significance.
2910
2911 For deliveries to pipes, files, and autoreplies, the duplicate checking
2912 still happens during the routing process, since they are not going to be
2913 routed further.

2958 consistency with the overall process timeout, these timeouts are now
2959 treated as errors, giving rise to delivery failures by default. However,
2960 there is now a new Boolean option for the pipe transport called

2972A note about Exim versions 4.44 and 4.50
2973----------------------------------------
2974
2975Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2976changes of various kinds. As a consequence, a big documentation update was
2977needed. This delayed the release for rather longer than seemed good, especially
2978in the light of a couple of (minor) security issues. Therefore, the changes
2979that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2980release. So 4.44 and 4.50 are in effect two different branches that both start
2981from 4.43.
2982
2983I have left the 4.50 change log unchanged; it contains all the changes since
29844.43. The change log for 4.44 is below; many of its items are identical to
2985those for 4.50. This seems to be the most sensible way to preserve the
2986historical information.

3004 5. There are several places where Exim runs a non-Exim command in a

3006 was being done only for the command run by the queryprogram router. It is
3007 now done for all such subprocesses. The other cases are: ${run, transport
3008 filters, and the commands run by the lmtp and pipe transports.

3015 systems. I've change it so that if it can't get 1000, it tries for 256.

306523. When checking ignore_target_hosts for an ipliteral router, no host name was
3066 being passed; this would have caused $sender_host_name to have been used if

308929. In an address list, if the pattern was not a regular expression, an empty
3090 subject address (from a bounce message) matched only if the pattern was an
3091 empty string. Non-empty patterns were not even tested. This was the wrong
3092 because it is perfectly reasonable to use an empty address as part of a
3093 database query. An empty address is now tested by patterns that are
3094 lookups. However, all the other forms of pattern expect the subject to
3095 contain a local part and a domain, and therefore, for them, an empty
3096 address still always fails if the pattern is not itself empty.

PH
310732. The RFC2047 encoding function was originally intended for short strings
3108 such as real names; it was not keeping to the 75-character limit for
3109 encoded words that the RFC imposes. It now respects the limit, and
3110 generates multiple encoded words if necessary. To be on the safe side, I
3111 have increased the buffer size for the ${rfc2047: expansion operator from
3112 1024 to 2048 bytes.
3113

PH
311433. It is now permitted to omit both strings after an "if" condition; if the
3115 condition is true, the result is "true". As before, when the second string
3116 is omitted, a false condition yields an empty string. This makes it less
3117 cumbersome to write custom ACL and router conditions.
3118

PH
312736. The table in the code that translates DNS record types into text (T_A to
3128 "A" for instance) was missing entries for NS and CNAME. It is just possible
3129 that this could have caused confusion if both these types were looked up
3130 for the same domain, because the text type is used as part of Exim's
3131 per-process caching. But the chance of anyone hitting this buglet seems
3132 very small.

PH
316443. Did the same fix as 41 above for OpenSSL, which had the same infelicity.
3165

PH
316644. The "Exiscan patch" is now merged into the mainline Exim source.
3167
316845. Sometimes the final signoff response after QUIT could fail to get
3169 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3170 < 0 before doing a fflush(). This bug looks as though it goes back to the
3171 introduction of TLS in release 3.20, but "sometimes" must have been rare
3172 because the tests only now provoked it.
3173

PH
317446. Reset the locale to "C" after calling embedded Perl, in case it was changed
3175 (this can affect the format of dates).
3176

PH
317747. exim_tidydb, when checking for the continued existence of a message for
3178 which it has found a message-specific retry record, was not finding
3179 messages that were in split spool directories. Consequently, it was
3180 deleting retry records that should have stayed in existence.
3181

PH
318248. Steve fixed some bugs in eximstats.
3183
318449. The SPA authentication driver was not abandoning authentication and moving
3185 on to the next authenticator when an expansion was forced to fail,
3186 contradicting the general specification for all authenticators. Instead it
3187 was generating a temporary error. It now behaves as specified.
3188
26dd5a95
PH
318950. The default ordering of permitted cipher suites for GnuTLS was pessimal
3190 (the order specifies the preference for clients). The order is now AES256,
3191 AES128, 3DES, ARCFOUR128.
3192
343b2385
PH
319351. Small patch to Sieve code - explicitly set From: when generating an
3194 autoreply.
3195
1c5466b9
PH
319652. Exim crashed if a remote delivery caused a very long error message to be
3197 recorded - for instance if somebody sent an entire SpamAssassin report back
3198 as a large number of 550 error lines. This bug was coincidentally fixed by
3199 increasing the size of one of Exim's internal buffers (big_buffer) that
3200 happened as part of the Exiscan merge. However, to be on the safe side, I
3201 have made the code more robust (and fixed the comments that describe what
3202 is going on).
3203
55ee9ee3
PH
320453. Now that there can be additional text after "Completed" in log lines (if
3205 the queue_time_overall log selector is set), a one-byte patch to exigrep
3206 was needed to allow it to recognize "Completed" as not the last thing in
3207 the line.
3208
d38f8232
PH
320954. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3210 patch that reportedly fixes this has been added. I am not expert enough to
3211 create a test for it. This is what the patch creator wrote:
3212
3213 "I found a little strange behaviour of ldap code when working with
3214 Windows 2003 AD Domain, where users was placed in more than one
3215 Organization Units. When I tried to give exim partial DN, the exit code
3216 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3217 But simultaneously result of request was absolutely normal ldap result,
3218 so I produce this patch..."
3219
3295e65b
PH
3220 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3221 REFERENCE, so I have modified the code to exclude the patch when that macro
3222 is not defined.
3223
7102e136
PH
322455. Some experimental protocols are using DNS PTR records for new purposes. The
3225 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3226 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3227 leaves it alone. Component reversal etc. now happens only for IP addresses.

323056. Improve error message when ldap_search() fails in OpenLDAP or Solaris LDAP.

PH
323257. Double the size of the debug message buffer (to 2048) so that more of very
3233 long debug lines gets shown.
3234
18ce445d
PH
323558. The exicyclog utility now does better if the number of log files to keep
3236 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
3237
1f5b4c3d
PH
323859. Two changes related to the smtp_active_hostname option:
3239
3240 (1) $smtp_active_hostname is now available as a variable.
3241 (2) The default for smtp_banner uses $smtp_active_hostname instead
3242 of $primary_hostname.
3243
b975ba52
PH
324460. The host_aton() function is supposed to be passed a string that is known
3245 to be a valid IP address. However, in the case of IPv6 addresses, it was
3246 not checking this. This is a hostage to fortune. Exim now panics and dies
3247 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3248 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3249 components; fortuitously, this particular loophole had already been fixed
3250 by change 4.50/55 above.
3251
3252 If there are any other similar loopholes, the new check in host_aton()
3253 itself should stop them being exploited. The report I received stated that
3254 data on the command line could provoke the exploit when Exim was running as
3255 exim, but did not say which command line option was involved. All I could
3256 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3257 running as the user.

326061. There was a buffer overflow vulnerability in the SPA authentication code
3261 (which came originally from the Samba project). I have added a test to the
3262 spa_base64_to_bits() function which I hope fixes it.

326562. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
3266 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
3267
d95f9fdb
PH
326863. The daemon start-up calls getloadavg() while still root for those OS that
3269 need the first call to be done as root, but it missed one case: when
3270 deliver_queue_load_max is set with deliver_drop_privilege. This is
3271 necessary for the benefit of the queue runner, because there is no re-exec
3272 when deliver_drop_privilege is set.
3273
86b8287f
PH
327464. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3275 This has been fixed.
3276
60dc5e56
PH
327765. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3278 was in use, was not putting the data itself into the right store pool;
3279 consequently, it could be overwritten for a subsequent message in the same
3280 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3281 the caching.)
3282
533244af
PH
328366. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3284
a5a28604
PH
328567. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3286 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3287 the function were treating the return as a boolean value, which happened to
3288 work because 0=false and not-0=true, but is not correct code.
3289
7e634d24
PH
329068. The host_aton() function was not handling scoped IPv6 addresses (those
3291 with, for example, "%eth0" on the end) correctly.
3292
3e11c26b
PH
329369. Fixed some compiler warnings in acl.c for the bitmaps specified with
3294 negated items (that is, ~something) in unsigned ints. Some compilers
3295 apparently mutter when there is no cast.
3296
6729cf78
PH
329770. If an address verification called from an ACL failed, and did not produce a
3298 user-specific message (i.e. there was only a "system" message), nothing was
3299 put in $acl_verify_message. In this situation, it now puts the system
3300 message there.
3301
00f00ca5
PH
330271. Change 4.23/11 added synchronization checking at the start of an SMTP
3303 session; change 4.31/43 added the unwanted input to the log line - except
3304 that it did not do this in the start of session case. It now does.
3305
c9bdd01c
PH
330672. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3307 This is wrong and can cause the other end to generate a synchronization
3308 error if it is another Exim or anything else that does the synchronization
3309 check. A QUIT command is no longer sent after a timeout.
3310
d43194df
PH
331173. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3312 during host lookups.
3313

PH
331474. The defer_ok option of callout verification was not working if it was used
3315 when verifying addresses in header lines, that is, for this case:
3316
3317 verify = header_sender/callout=defer_ok
3318
76a2d7ba
PH
331975. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3320 those file descriptors could be used for SMTP connections. If anything
3321 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3322 could be sent to the SMTP client, causing chaos. The daemon now opens
3323 stdin, stdout, and stderr to /dev/null when it puts itself into the
3324 background.
3325
332676. Arrange for output from Perl's "warn" command to be written to Exim's main
3327 log by default. The user can override this with suitable Perl magic.
3328
04f7d5b9
PH
332977. The use of log_message on a "discard" ACL verb, which is supposed to add to
3330 the log message when discard triggers, was not working for the DATA ACL or
3331 for the non-SMTP ACL.
3332
bc60667e
PH
333378. Error message wording change in sieve.c.
3334
bb6e88ff
PH
333579. If smtp_accept_max_per_host was set, the number of connections could be
3336 restricted to fewer than expected, because the daemon was trying to set up
3337 a new connection before checking whether the processes handling previous
3338 connections had finished. The check for completed processes is now done
3339 earlier. On busy systems, this bug wouldn't be noticed because something
3340 else would have woken the daemon, and it would have reaped the completed
3341 process earlier.
3342
1e70f85b
PH
334380. If a message was submitted locally by a user whose login name contained one
3344 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3345 It caused a spool format error. I have fixed the spool reading code. A
3346 related problem was that the "from" clause in the Received: line became
3347 illegal because of the space(s). It is now covered by ${quote_local_part.
3348
334981. Included the latest eximstats from Steve (adds average sizes to HTML Top
3350 tables).

3363----------------------------------------------------
3364See the note above about the 4.44 and 4.50 releases.
3365----------------------------------------------------
3366
3367
3368Exim version 4.44
3369-----------------
3370
3371 1. Change 4.43/35 introduced a bug that caused file counts to be
3372 incorrectly computed when quota_filecount was set in an appendfile
3373 transport
3374
3375 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3376 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3377 place.
3378
3379 3. Give more explanation in the error message when the command for a transport
3380 filter fails to execute.
3381
3382 4. There are several places where Exim runs a non-Exim command in a
3383 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3384 was being done only for the command run by the queryprogram router. It is
3385 now done for all such subprocesses. The other cases are: ${run, transport
3386 filters, and the commands run by the lmtp and pipe transports.
3387
3388 5. Some older OS have a limit of 256 on the maximum number of file
3389 descriptors. Exim was using setrlimit() to set 1000 as a large value
3390 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3391 systems. I've change it so that if it can't get 1000, it tries for 256.
3392
3393 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3394 was an oversight, and furthermore, ever since the addition of extra
3395 controls (e.g. 4.43/32), the checks on when to allow different forms of
3396 "control" were broken. There should now be diagnostics for all cases when a
3397 control that does not make sense is encountered.
3398
3399 7. $recipients is now available in the predata ACL (oversight).
3400
3401 8. Tidy the search cache before the fork to do a delivery from a message
3402 received from the command line. Otherwise the child will trigger a lookup
