68PP/14 TLS fixes for OpenSSL: support TLS 1.1 & 1.2; new "openssl_options"
69 values; set SSL_MODE_AUTO_RETRY so that OpenSSL will retry a read
70 or write after TLS renegotiation, which otherwise led to messages
71 "Got SSL error 2".

JH
117 This may cause build issues on older platforms.
118
17c76198
PP
119PP/25 Revamped GnuTLS support, passing tls_require_ciphers to
120 gnutls_priority_init, ignoring Exim options gnutls_require_kx,
121 gnutls_require_mac & gnutls_require_protocols (no longer supported).
122 Added SNI support via GnuTLS too.
af3498d6 123 Made ${randint:..} supplier available, if using not-too-old GnuTLS.

137PP/29 Fix three issues highlighted by clang analyser static analysis.
138 Only crash-plausible issue would require the Cambridge-specific
139 iplookup router and a misconfiguration.
140 Report from Marcin Mirosław.
141
6475bd82
PP
142PP/30 Another attempt to deal with PCRE_PRERELEASE, this one less buggy.
143
81f91683
PP
144PP/31 %D in printf continues to cause issues (-Wformat=security), so for
145 now guard some of the printf checks behind WANT_DEEPER_PRINTF_CHECKS.
146 As part of this, removing so much warning spew let me fix some minor
147 real issues in debug logging.
148
5779e6aa
PP
149PP/32 GnuTLS was always using default tls_require_ciphers, due to a missing
150 assignment on my part. Fixed.
151
3375e053
PP
152PP/33 Added tls_dh_max_bits option, defaulting to current hard-coded limit
153 of NSS, for GnuTLS/NSS interop. Problem root cause diagnosis by
154 Janne Snabb (who went above and beyond: thank you).
155
156PP/34 Validate tls_require_ciphers on startup, since debugging an invalid
157 string otherwise requires a connection and a bunch more work and it's
78e0c7a3
PP
158 relatively easy to get wrong. Should also expose TLS library linkage
159 problems.

162 64-bit ${eval} (JH/03).
163
57eb9e91 164PP/36 Define _GNU_SOURCE in exim.h; it's needed for some releases of
b87a6e0e
PP
165 GNU libc to support some of the 64-bit stuff, should not lead to
166 conflicts. Defined before os.h is pulled in, so if a given platform
167 needs to override this, it can.
168
16880d1a
PP
169PP/37 Unbreak Cyrus SASL auth: SSF retrieval was incorrect, Exim thought
170 protection layer was required, which is not implemented.
171 Bugzilla 1254, patch from Wolfgang Breyha.
172
a799883d
PP
173PP/38 Overhaul DH prime handling, supply RFC-specified DH primes as built
174 into Exim, default to IKE id 23 from RFC 5114 (2048 bit). Make
175 tls_dhparam take prime identifiers. Also unbreak combination of
176 OpenSSL+DH_params+TLSSNI.
177

193 when unlink() failed. See also change 4.74-TF/03.
194
921b12ca
TF
195TF/03 Make the exiwhat support code safe for signals. Previously Exim might
196 lock up or crash if it happened to be inside a call to libc when it
197 got a SIGUSR1 from exiwhat.
198
199 The SIGUSR1 handler appends the current process status to the process
200 log which is later printed by exiwhat. It used to use the general
201 purpose logging code to do this, but several functions it calls are
202 not safe for signals.
203
204 The new output code in the SIGUSR1 handler is specific to the process
205 log, and simple enough that it's easy to inspect for signal safety.
206 Removing some special cases also simplifies the general logging code.
207 Removing the spurious timestamps from the process log simplifies
208 exiwhat.
209

TF
210TF/04 Improved ratelimit ACL condition.
211
212 The /noupdate option has been deprecated in favour of /readonly which
213 has clearer semantics. The /leaky, /strict, and /readonly update modes
214 are mutually exclusive. The update mode is no longer included in the
215 database key; it just determines when the database is updated. (This
216 means that when you upgrde Exim will forget old rate measurements.)
217
218 Exim now checks that the per_* options are used with an update mode that
219 makes sense for the current ACL. For example, when Exim is processing a
220 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
221 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
222 must specify per_mail/readonly. If you omit the update mode it defaults to
223 /leaky where that makes sense (as before) or /readonly where required.
224
225 The /noupdate option is now undocumented but still supported for
226 backwards compatibility. It is equivalent to /readonly except that in
227 ACLs where /readonly is required you may specify /leaky/noupdate or
228 /strict/noupdate which are treated the same as /readonly.
229
230 A useful new feature is the /count= option. This is a generalization
231 of the per_byte option, so that you can measure the throughput of other
232 aggregate values. For example, the per_byte option is now equivalent
233 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
234
235 The per_rcpt option has been generalized using the /count= mechanism
236 (though it's more complicated than the per_byte equivalence). When it is
237 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
238 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
239 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
240 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
241 Note that using per_rcpt with a non-readonly update mode in more than
242 one ACL will cause the recipients to be double-counted. (The per_mail
243 and per_byte options don't have this problem.)
244
245 The handling of very low rates has changed slightly. If the computed rate
246 is less than the event's count (usually one) then this event is the first
247 after a long gap. In this case the rate is set to the same as this event's
248 count, so that the first message of a spam run is counted properly.
249
250 The major new feature is a mechanism for counting the rate of unique
251 events. The new per_addr option counts the number of different
252 recipients that someone has sent messages to in the last time period. It
253 behaves like per_rcpt if all the recipient addresses are different, but
254 duplicate recipient addresses do not increase the measured rate. Like
255 the /count= option this is a general mechanism, so the per_addr option
256 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
257 example, measure the rate that a client uses different sender addresses
258 with the options per_mail/unique=$sender_address. There are further
259 details in the main documentation.

831PH/01 Another patch from the Sieve maintainer.
832
6a3bceb1
PH
833PH/02 When an IPv6 address is converted to a string for single-key lookup
834 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
835 dots are used instead of colons so that keys in lsearch files need not
836 contain colons. This was done some time before quoting was made available
837 in lsearch files. However, iplsearch files do require colons in IPv6 keys
838 (notated using the quote facility) so as to distinguish them from IPv4
839 keys. This meant that lookups for IP addresses in host lists did not work
840 for iplsearch lookups.
841
842 This has been fixed by arranging for IPv6 addresses to be expressed with
843 colons if the lookup type is iplsearch. This is not incompatible, because
844 previously such lookups could never work.
845
846 The situation is now rather anomolous, since one *can* have colons in
847 ordinary lsearch keys. However, making the change in all cases is
848 incompatible and would probably break a number of configurations.

853MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
854 conversion specification without a maximum field width, thereby enabling
855 a rogue spamd server to cause a buffer overflow. While nobody in their
856 right mind would setup Exim to query an untrusted spamd server, an
857 attacker that gains access to a server running spamd could potentially
858 exploit this vulnerability to run arbitrary code as the Exim user.

MH
863MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
864 a directory entry by the name of the lookup key. Previously, if a
865 symlink pointed to a non-existing file or a file in a directory that
866 Exim lacked permissions to read, a lookup for a key matching that
867 symlink would fail. Now it is enough that a matching directory entry
868 exists, symlink or not. (Bugzilla 503.)

1051PH/29 SMTP synchronization checks are implemented when a command is read -
1052 there is a check that no more input is waiting when there shouldn't be

1054 some time before the response is written. In this time, more input might
1055 arrive, invalidly. So now there are extra checks after an ACL has run for
1056 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1057 pipelining has not been advertised.

1131 the response to the final '.' that terminates a message, but only in the
1132 case where the client has not sent further data following the '.'
1133 (unfortunately, this is allowed). However, in many cases there won't be
1134 any further data because there won't be any more messages to send. A call
1135 to select() can be used: if it shows that the input is "ready", there is
1136 either input waiting, or the socket has been closed. An attempt to read
1137 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1138 would have sent an OK response which the client would never have see.

1149PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1150 fixed by 4.65/MH/01 (is this a record?) are fixed:
1151
1152 (i) An empty string was always treated as zero by the numeric comparison
1153 operators. This behaviour has been restored.
1154
1155 (ii) It is documented that the numeric comparison operators always treat
1156 their arguments as decimal numbers. This was broken in that numbers
1157 starting with 0 were being interpreted as octal.
1158
1159 While fixing these problems I realized that there was another issue that
1160 hadn't been noticed. Values of message_size_limit (both the global option
1161 and the transport option) were treated as octal if they started with 0.
1162 The documentation was vague. These values are now always treated as
1163 decimal, and I will make that clear in the documentation.

1196 triggering a timeout which in turn triggers #401.
1197
1198TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1199 in the DK code in transports.c. sendfile() is not really portable,
1200 hence the _LINUX specificness.

1202TF/01 In the add_headers option to the mail command in an Exim filter,
1203 there was a bug that Exim would claim a syntax error in any
1204 header after the first one which had an odd number of characters
1205 in the field name.

PH
1207PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1208 callout verification, Exim cached a "reject" for the entire domain. This
1209 is correct for most verifications, but it is not correct for a recipient
1210 verification with use_sender or use_postmaster set, because in that case
1211 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1212 case of MAIL FROM:<> rejection from other early rejections (e.g.
1213 rejection of HELO). When verifying a recipient using a non-null MAIL
1214 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1215 Whatever the result of the callout, the value of the domain cache is
1216 left unchanged (for any other kind of callout, getting as far as trying
1217 RCPT means that the domain itself is ok).

1251PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1252 hostname. This is wrong, because it relates to the incoming message (and
1253 probably the interface on which it is arriving) and not to the outgoing
1254 callout (which could be using a different interface). This has been
1255 changed to use the value of the helo_data option from the smtp transport
1256 instead - this is what is used when a message is actually being sent. If
1257 there is no remote transport (possible with a router that sets up host
1258 addresses), $smtp_active_hostname is used.

14aa5a05 1260PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1261 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1262 (a) The code assumed that strncpy() returns a negative number on buffer
1263 overflow, which isn't the case. Replaced with Exim's string_format()
1264 function.
1265 (b) There were several signed/unsigned issues. I just did the minimum
1266 hacking in of casts. There is scope for a larger refactoring.
1267 (c) The code used strcasecmp() which is not a standard C function.
1268 Replaced with Exim's strcmpic() function.
1269 (d) The code set only $1; it now sets $auth1 as well.
1270 (e) A simple test gave the error "authentication client didn't specify
1271 service in request". It would seem that Dovecot has changed its
1272 interface. Fortunately there's a specification; I followed it and
1273 changed what the client sends and it appears to be working now.

PH
1278PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1279 address A is aliased to B and C, where B exists and C does not. Without
1280 -v the output is "A verified" because verification stops after a
1281 successful redirection if more than one address is generated. However,
1282 with -v the child addresses are also verified. Exim was outputting "A
1283 failed to verify" and then showing the successful verification for C,
1284 with its parentage. It now outputs "B failed to verify", showing B's
1285 parentage before showing the successful verification of C.

1287PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
1288 look up a TXT record in a specific list after matching in a combined
1289 list.
1290
322050c2
PH
1291PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1292 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1293 they consult the DNS. I had assumed they would set it the way they
1294 wanted; and indeed my experiments on Linux seem to show that in some
1295 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1296 To be on the safe side, however, I have now made the interface to
1297 host_find_byname() similar to host_find_bydns(), with an argument
1298 containing the DNS resolver options. The host_find_byname() function now
1299 sets these options at its start, just as host_find_bydns() does. The smtp
1300 transport options dns_qualify_single and dns_search_parents are passed to
1301 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1302 of host_find_byname() use the default settings of RES_DEFNAMES
1303 (qualify_single) but not RES_DNSRCH (search_parents).
1304
08955dd3
PH
1305PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1306 spool_read_header() do less string testing, by means of a preliminary
1307 switch on the second character of optional "-foo" lines. (This is
1308 overdue, caused by the large number of possibilities that now exist.
1309 Originally there were few.) While I was there, I also converted the
1310 str(n)cmp tests so they don't re-test the leading "-" and the first
1311 character, in the hope this might squeeze out yet more improvement.
1312

PH
1313PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1314 flag allowing group syntax was set by the header_syntax check but not
1315 turned off, possible causing trouble later; (2) The flag was not being
1316 set at all for the header_verify test, causing "group"-style headers to
1317 be rejected. I have now set it in this case, and also caused header_
1318 verify to ignore an empty address taken from a group. While doing this, I
1319 came across some other cases where the code for allowing group syntax
1320 while scanning a header line wasn't quite right (mostly, not resetting
1321 the flag correctly in the right place). These bugs could have caused
1322 trouble for malformed header lines. I hope it is now all correct.
1323
602e59e5
PH
1324PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1325 with the "reply" argument non-NULL. The code, however (which originally
1326 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1327 but it didn't always do it. This confused somebody who was copying the
1328 code for some other use. I have removed all the tests.

PH
1330PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1331 feature that was used to support insecure browsers during the U.S. crypto
1332 embargo. It requires special client support, and Exim is probably the
1333 only MTA that supported it -- and would never use it because real RSA is
1334 always available. This code has been removed, because it had the bad
1335 effect of slowing Exim down by computing (never used) parameters for the
1336 RSA_EXPORT functionality.

7befa435
PH
1338PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1339 authenticator to fail if there's a tab character in the incoming data
1340 (there should never be unless someone is messing about, as it's supposed
1341 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1342 if the connection is using TLS or if the remote IP is the same as the
1343 local IP, and the "valid-client-cert option" if a client certificate has
1344 been verified.

1375
1376PH/30 Exim was sometimes attempting to deliver messages that had suffered
1377 address errors (4xx response to RCPT) over the same connection as other
1378 messages routed to the same hosts. Such deliveries are always "forced",
1379 so retry times are not inspected. This resulted in far too many retries
1380 for the affected addresses. The effect occurred only when there were more
1381 hosts than the hosts_max_try setting in the smtp transport when it had
1382 the 4xx errors. Those hosts that it had tried were not added to the list
1383 of hosts for which the message was waiting, so if all were tried, there
1384 was no problem. Two fixes have been applied:
1385
1386 (i) If there are any address or message errors in an SMTP delivery, none
1387 of the hosts (tried or untried) are now added to the list of hosts
1388 for which the message is waiting, so the message should not be a
1389 candidate for sending over the same connection that was used for a
1390 successful delivery of some other message. This seems entirely
1391 reasonable: after all the message is NOT "waiting for some host".
1392 This is so "obvious" that I'm not sure why it wasn't done
1393 previously. Hope I haven't missed anything, but it can't do any
1394 harm, as the worst effect is to miss an optimization.
1395
1396 (ii) If, despite (i), such a delivery is accidentally attempted, the
1397 routing retry time is respected, so at least it doesn't keep
1398 hammering the server.

PH
1413PH/35 The error "getsockname() failed: connection reset by peer" was being
1414 written to the panic log as well as the main log, but it isn't really
1415 panic-worthy as it just means the connection died rather early on. I have
1416 removed the panic log writing for the ECONNRESET error when getsockname()
1417 fails.
1418
48c7f9e2
PH
1419PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1420 runs only) independently of the message's sender address. This meant
1421 that, if the 4xx error was in fact related to the sender, a different
1422 message to the same recipient with a different sender could confuse
1423 things. In particualar, this can happen when sending to a greylisting
1424 server, but other circumstances could also provoke similar problems.
1425 I have changed the default so that the retry time for these errors is now
1426 based a combination of the sender and recipient addresses. This change
1427 can be overridden by setting address_retry_include_sender=false in the
1428 smtp transport.

1696PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

1698 Unfortunately, if there is a major crisis, such as a disk failure,
1699 tcp-wrappers gives "deny", whereas what one would like would be some
1700 kind of temporary error. A kludge has been added to help with this.
1701 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1702 554 error is used if errno is still zero or contains ENOENT (which occurs
1703 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1704 451 error is used.

1740PH/01 The code for finding all the local interface addresses on a FreeBSD
1741 system running IPv6 was broken. This may well have applied to all BSD
1742 systems, as well as to others that have similar system calls. The broken
1743 code found IPv4 interfaces correctly, but gave incorrect values for the
1744 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1745 that it would not match correctly against @[] and not recognize the IPv6
1746 addresses as local.

1788 generate an autoreply, and therefore failed to obtain an address for the
1789 autoreply, Exim could try to deliver to a non-existent relative file
1790 name, causing unrelated and misleading errors. What now happens is that

1809 non-existent - all you got was a failure to exec. I have made two
1810 changes:
1811
1812 (a) Failures to set uid/gid, the current directory, or a process leader
1813 in a subprocess such as that created by queryprogram now generate
1814 suitable debugging ouput when -d is set.
1815
1816 (b) The queryprogram router detects when it is not running as root,
1817 outputs suitable debugging information if -d is set, and then runs
1818 the subprocess without attempting to change uid/gid.

1823PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1824 additional section of a DNS packet that returns MX or SRV records.
1825 Instead, it always explicitly searches for A/AAAA records. This avoids
1826 major problems that occur when a DNS server includes only records of one
1827 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1828 fixed another bug: if SRV records were looked up and the corresponding
1829 address records were *not* found in the additional section, the port
1830 values from the SRV records were lost.

PH
1832PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

727071f8
PH
1840PH/19 When calculating a retry time, Exim used to measure the "time since
1841 failure" by looking at the "first failed" field in the retry record. Now
1842 it does not use this if it is later than than the arrival time of the
1843 message. Instead it uses the arrival time. This makes for better
1844 behaviour in cases where some deliveries succeed, thus re-setting the
1845 "first failed" field. An example is a quota failure for a huge message
1846 when small messages continue to be delivered. Without this change, the
1847 "time since failure" will always be short, possible causing more frequent
1848 delivery attempts for the huge message than are intended.

1945PH/42 The content-scanning code uses fopen() to create files in which to put

1948 files with open(), and sets the required mode explicitly. Thus, these
1949 files were ending up world-writeable. This was not a big issue, because,
1950 being within the spool directory, they were not world-accessible. I have
1951 created a function called modefopen, which takes an additional mode
1952 argument. It sets umask(777), creates the file, chmods it to the required
1953 mode, then resets the umask. All the relevant calls to fopen() in the

1965 received. Setting client_ignore_invalid_base64 true ignores these errors.
1966 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
1967 they are received. Thus, the responses can be made to depend on the
1968 challenges. If an invalid string is ignored, an empty string is placed in
1969 the variable.

1989PH/52 Two bugs concerned with error handling when the smtp transport is
1990 used in LMTP mode:
1991
1992 (i) Exim was not creating retry information for temporary errors given
1993 for individual recipients after the DATA command when the smtp transport
1994 was used in LMTP mode. This meant that they could be retried too
1995 frequently, and not timed out correctly.
1996
1997 (ii) Exim was setting the flag that allows error details to be returned
1998 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1999 recipients that were returned after the DATA command.
2000
2001PH/53 This is related to PH/52, but is more general: for any failing address,
2002 when detailed error information was permitted to be returned to the
2003 sender, but the error was temporary, then after the final timeout, only
2004 "retry timeout exceeded" was returned. Now it returns the full error as

2075PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2076 function verify_get_ident() calls ip_connect() to connect a socket, but
2077 if the "connect()" function timed out, ip_connect() used to close the
2078 socket. However, verify_get_ident() also closes the socket later, and in
2079 between Exim writes to the log, which may get opened at this point. When
2080 the socket was closed in ip_connect(), the log could get the same file
2081 descriptor number as the socket. This naturally causes chaos. The fix is
2082 not to close the socket in ip_connect(); the socket should be closed by
2083 the function that creates it. There was only one place in the code where
2084 this was missing, in the iplookup router, which I don't think anybody now
2085 uses, but I've fixed it anyway.

2108
2109 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2110 string.
2111
2112 (3) Reset the variables that are obtained from the first argument of
2113 ${prvscheck and used in the second argument before leaving the code,
2114 because their memory is reclaimed, so using them afterwards may do
2115 silly things.
2116
2117 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2118 one (it's much easier than Tom thought :-).

2142 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2143 not being looked up in the rDNS to get a host name, Exim was showing the
2144 IP address twice in Received: lines, even though the IP addresses were
2145 identical. For example:
2146
2147 Received: from [1.2.3.4] (helo=[1.2.3.4])
2148
2149 However, if the real host name was known, it was omitting the HELO data
2150 if it matched the actual IP address. This has been tidied up so that it
2151 doesn't show the same IP address twice.

2179
2180 Auto-submitted: auto-generated

2182 in the messages that it generates (bounce messages and others, such as
2183 warnings). In the case of bounce messages for non-SMTP mesages, there was
2184 also a typo: it was using "Auto_submitted" (underscore instead of
2185 hyphen). Since every message generated by Exim is necessarily in response
2186 to another message, thes have all been changed to:
2187
2188 Auto-Submitted: auto-replied
2189
2190 in accordance with these statements in the RFC:
2191
2192 The auto-replied keyword:
2193
2194 - SHOULD be used on messages sent in direct response to another

2242 the IP address, check_host() was doing a simple string comparison with
2243 addresses acquired from the DNS when checking that the found name did
2244 have the original IP as one of its addresses. Since any found IPv6
2245 addresses are likely to be in abbreviated form, the comparison could
2246 fail. Luckily, there already exists a function for doing the comparison
2247 by converting both addresses to binary, so now that is used instead of
2248 the text comparison.

2546 with the definition in sysexits.h (which is #included earlier).
2547 Fortunately, Exim does not actually use EX_OK. The code used to try to
2548 preserve the sysexits.h value, by assumimg that macro definitions were
2549 scanned for macro replacements. I have been disabused of this notion,

2555 This seems wrong - if the receiver was accepting one byte at a time it
2556 would take for ever. The timeout is now adjusted when this happens. It
2557 doesn't have to be particularly precise.

2769 if the data in the cache doesn't make sense, Exim assumes it has read an
2770 old-format file, and it generates new data and writes a new file. This
2771 means that you can't go back to an older release without removing the
2772 file.
2773
2774PH/03 A redirect router that has both "unseen" and "one_time" set does not
2775 work if there are any delivery delays because "one_time" forces the
2776 parent to be marked "delivered", so its unseen clone is never tried
2777 again. For this reason, Exim now forbids the simultaneous setting of
2778 these two options.
2779
2780PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2781 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2782 entry if you want to know the details. The fix, however, neglected to
2783 consider the case when local delivery batching is involved. The test for
2784 "previously delivered" was not happening when checking to see if an
2785 address could be batched with a previous (undelivered) one; under
2786 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2787 address.

2789PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
2790 in its include files, and this causes problems building Exim.
2791
2792PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2793 header_syntax) but Exim was just ignoring anything given after a slash.
2794 In particular, this caused confusion with an attempt to use "verify =
2795 reverse_host_lookup/defer_ok". An error is now given when options are
2796 supplied for verify items that do not have them. (Maybe reverse_host_
2797 lookup should have a defer_ok option, but that's a different point.)
2798
2799PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
2800 defined by RFC 821) to 2048, because there were problems with some AUTH

2849PH/19 When an Exim process that is running as root has to create an Exim log
2850 file, it does so in a subprocess that runs as exim:exim so as to get the
2851 ownership right at creation (otherwise, other Exim processes might see
2852 the file with the wrong ownership). There was no test for failure of this
2853 fork() call, which would lead to the process getting stuck as it waited
2854 for a non-existent subprocess. Forks do occasionally fail when resources
2855 run out. I reviewed all the other calls to fork(); they all seem to check
2856 for failure.

2858PH/20 When checking for unexpected SMTP input at connect time (before writing

2861 the result was a log entry for a synchronization error with an empty
2862 string after "input=" when read() returned zero. If read() returned -1

PH
2875PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2876 hadn't been configured. The fix is from Juergen Kreileder, who
2877 understands it better than I do:
2878
2879 "Here's what I see happening with three configured cyrus_sasl
2880 authenticators configured (plain, login, cram-md5):
2881
2882 On startup auth_cyrus_sasl_init() gets called for each of these.
2883 This means three calls to sasl_listmech() without a specified mech_list.
2884 => SASL tests which mechs of all available mechs actually work
2885 => three warnings about OTP not working
2886 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2887
2888 With the patch, sasl_listmech() also gets called three times. But now
2889 SASL's mech_list option is set to the server_mech specified in the the
2890 authenticator. Or in other words, the answer from sasl_listmech()
2891 gets limited to just the mech you're testing for (which is different
2892 for each call.)
2893 => the return list contains just 'plain' or 'login', 'cram-md5' or
2894 nothing depending on the value of ob->server_mech.
2895
2896 I've just tested the patch: Authentication still works fine,

PH
2962PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2963 the grounds that routing the same address twice would always produce the
2964 same answer. This might have been true once, but it is certainly no
2965 longer true now. Routing a child address may depend on the previous
2966 routing that produced that child. Some complicated redirection strategies
2967 went wrong when messages had multiple recipients, and made Exim's
2968 behaviour dependent on the order in which the addresses were given.
2969
2970 I have moved the duplicate checking until after the routing is complete.
2971 Exim scans the addresses that are assigned to local and remote
2972 transports, and removes any duplicates. This means that more work will be
2973 done, as duplicates will always all be routed, but duplicates are
2974 presumably rare, so I don't expect this is of any significance.
2975
2976 For deliveries to pipes, files, and autoreplies, the duplicate checking
2977 still happens during the routing process, since they are not going to be
2978 routed further.

3023 consistency with the overall process timeout, these timeouts are now
3024 treated as errors, giving rise to delivery failures by default. However,
3025 there is now a new Boolean option for the pipe transport called
3026 timeout_defer, which, if set TRUE, converts the failures into defers for
3027 both kinds of timeout. A transport filter timeout is now identified in

3037A note about Exim versions 4.44 and 4.50
3038----------------------------------------
3039
3040Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3041changes of various kinds. As a consequence, a big documentation update was
3042needed. This delayed the release for rather longer than seemed good, especially
3043in the light of a couple of (minor) security issues. Therefore, the changes
3044that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3045release. So 4.44 and 4.50 are in effect two different branches that both start
3046from 4.43.
3047
3048I have left the 4.50 change log unchanged; it contains all the changes since
30494.43. The change log for 4.44 is below; many of its items are identical to
3050those for 4.50. This seems to be the most sensible way to preserve the
3051historical information.

3073 filters, and the commands run by the lmtp and pipe transports.

3080 systems. I've change it so that if it can't get 1000, it tries for 256.

3157 because it is perfectly reasonable to use an empty address as part of a
3158 database query. An empty address is now tested by patterns that are
3159 lookups. However, all the other forms of pattern expect the subject to
3160 contain a local part and a domain, and therefore, for them, an empty
3161 address still always fails if the pattern is not itself empty.

3164 host was specified on an smtp transport, and looking it up yielded more
3165 than one IP address.
3166
5cb8cbc6
PH
316731. Re-factored the code for checking spool and log partition space into a
3168 function that finds that data and another that does the check. The former
3169 is then used to implement four new variables: $spool_space, $log_space,
3170 $spool_inodes, and $log_inodes.

PH
317232. The RFC2047 encoding function was originally intended for short strings
3173 such as real names; it was not keeping to the 75-character limit for
3174 encoded words that the RFC imposes. It now respects the limit, and
3175 generates multiple encoded words if necessary. To be on the safe side, I
3176 have increased the buffer size for the ${rfc2047: expansion operator from
3177 1024 to 2048 bytes.
3178
063b1e99
PH
317933. It is now permitted to omit both strings after an "if" condition; if the
3180 condition is true, the result is "true". As before, when the second string
3181 is omitted, a false condition yields an empty string. This makes it less
3182 cumbersome to write custom ACL and router conditions.
3183
652e1b65
PH
318434. Failure to deliver a bounce message always caused it to be frozen, even if
3185 there was an errors_to setting on the router. The errors_to setting is now
3186 respected.
3187
6f0c9a4f
PH
318835. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3189 canonical form (fully expanded) before being placed in
3190 $sender_host_address.
3191
33397d19
PH
319236. The table in the code that translates DNS record types into text (T_A to
3193 "A" for instance) was missing entries for NS and CNAME. It is just possible
3194 that this could have caused confusion if both these types were looked up
3195 for the same domain, because the text type is used as part of Exim's
3196 per-process caching. But the chance of anyone hitting this buglet seems
3197 very small.
3198
7bb56e1f
PH
319937. The dnsdb lookup has been extended in a number of ways.
3200
3201 (1) There is a new type, "zns", which walks up the domain tree until it
3202 finds some nameserver records. It should be used with care.
3203
ea3bc19b
PH
3204 (2) There is a new type, "mxh", which is like "mx" except that it returns
3205 just the host names, not the priorities.
3206
3207 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
3208 looked up. The behaviour when one of the lookups defers can be
3209 controlled by a keyword.
7bb56e1f 3210
ea3bc19b 3211 (4) It is now possible to specify the separator character for use when
7bb56e1f 3212 multiple records are returned.
33397d19 3213
0bcb2a0e
PH
321438. The dnslists ACL condition has been extended: it is now possible to supply
3215 a list of IP addresses and/or domains to be looked up in a particular DNS
3216 domain.

de365ded
PH
322341. Include certificate and key file names in error message when GnuTLS fails
3224 to set them up, because the GnuTLS error message doesn't include the name
3225 of the failing file when there is a problem reading it.

PH
323144. The "Exiscan patch" is now merged into the mainline Exim source.
3232
323345. Sometimes the final signoff response after QUIT could fail to get
3234 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3235 < 0 before doing a fflush(). This bug looks as though it goes back to the
3236 introduction of TLS in release 3.20, but "sometimes" must have been rare
3237 because the tests only now provoked it.

323946. Reset the locale to "C" after calling embedded Perl, in case it was changed
3240 (this can affect the format of dates).

PH
324247. exim_tidydb, when checking for the continued existence of a message for
3243 which it has found a message-specific retry record, was not finding
3244 messages that were in split spool directories. Consequently, it was
3245 deleting retry records that should have stayed in existence.

PH
324748. Steve fixed some bugs in eximstats.
3248
324949. The SPA authentication driver was not abandoning authentication and moving
3250 on to the next authenticator when an expansion was forced to fail,
3251 contradicting the general specification for all authenticators. Instead it
3252 was generating a temporary error. It now behaves as specified.
3253

PH
325450. The default ordering of permitted cipher suites for GnuTLS was pessimal
3255 (the order specifies the preference for clients). The order is now AES256,
3256 AES128, 3DES, ARCFOUR128.

325851. Small patch to Sieve code - explicitly set From: when generating an
3259 autoreply.

PH
326152. Exim crashed if a remote delivery caused a very long error message to be
3262 recorded - for instance if somebody sent an entire SpamAssassin report back
3263 as a large number of 550 error lines. This bug was coincidentally fixed by
3264 increasing the size of one of Exim's internal buffers (big_buffer) that
3265 happened as part of the Exiscan merge. However, to be on the safe side, I
3266 have made the code more robust (and fixed the comments that describe what
3267 is going on).
3268

PH
326953. Now that there can be additional text after "Completed" in log lines (if
3270 the queue_time_overall log selector is set), a one-byte patch to exigrep
3271 was needed to allow it to recognize "Completed" as not the last thing in
3272 the line.

PH
327454. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3275 patch that reportedly fixes this has been added. I am not expert enough to
3276 create a test for it. This is what the patch creator wrote:
3277
3278 "I found a little strange behaviour of ldap code when working with
3279 Windows 2003 AD Domain, where users was placed in more than one
3280 Organization Units. When I tried to give exim partial DN, the exit code
3281 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3282 But simultaneously result of request was absolutely normal ldap result,
3283 so I produce this patch..."
3284
3295e65b
PH
3285 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3286 REFERENCE, so I have modified the code to exclude the patch when that macro
3287 is not defined.
3288

PH
328955. Some experimental protocols are using DNS PTR records for new purposes. The
3290 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3291 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3292 leaves it alone. Component reversal etc. now happens only for IP addresses.

PH
330058. The exicyclog utility now does better if the number of log files to keep

PH
330359. Two changes related to the smtp_active_hostname option:
3304
3305 (1) $smtp_active_hostname is now available as a variable.
3306 (2) The default for smtp_banner uses $smtp_active_hostname instead
3307 of $primary_hostname.
3308
b975ba52
PH
330960. The host_aton() function is supposed to be passed a string that is known
3310 to be a valid IP address. However, in the case of IPv6 addresses, it was
3311 not checking this. This is a hostage to fortune. Exim now panics and dies
3312 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3313 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3314 components; fortuitously, this particular loophole had already been fixed
3315 by change 4.50/55 above.
3316
3317 If there are any other similar loopholes, the new check in host_aton()
3318 itself should stop them being exploited. The report I received stated that
3319 data on the command line could provoke the exploit when Exim was running as
3320 exim, but did not say which command line option was involved. All I could
3321 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3322 running as the user.

PH
333363. The daemon start-up calls getloadavg() while still root for those OS that
3334 need the first call to be done as root, but it missed one case: when
3335 deliver_queue_load_max is set with deliver_drop_privilege. This is
3336 necessary for the benefit of the queue runner, because there is no re-exec
3337 when deliver_drop_privilege is set.
3338

PH
333964. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3340 This has been fixed.
3341
60dc5e56
PH
334265. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3343 was in use, was not putting the data itself into the right store pool;
3344 consequently, it could be overwritten for a subsequent message in the same
3345 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3346 the caching.)
3347

PH
334866. Added hosts_max_try_hardlimit to the smtp transport, default 50.

PH
335067. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3351 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3352 the function were treating the return as a boolean value, which happened to
3353 work because 0=false and not-0=true, but is not correct code.
3354
7e634d24
PH
335568. The host_aton() function was not handling scoped IPv6 addresses (those
3356 with, for example, "%eth0" on the end) correctly.

PH
335869. Fixed some compiler warnings in acl.c for the bitmaps specified with
3359 negated items (that is, ~something) in unsigned ints. Some compilers
3360 apparently mutter when there is no cast.

PH
336270. If an address verification called from an ACL failed, and did not produce a
3363 user-specific message (i.e. there was only a "system" message), nothing was
3364 put in $acl_verify_message. In this situation, it now puts the system
3365 message there.
3366
00f00ca5
PH
336771. Change 4.23/11 added synchronization checking at the start of an SMTP
3368 session; change 4.31/43 added the unwanted input to the log line - except
3369 that it did not do this in the start of session case. It now does.
3370
c9bdd01c
PH
337172. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3372 This is wrong and can cause the other end to generate a synchronization
3373 error if it is another Exim or anything else that does the synchronization
3374 check. A QUIT command is no longer sent after a timeout.

337673. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3377 during host lookups.

PH
337974. The defer_ok option of callout verification was not working if it was used
3380 when verifying addresses in header lines, that is, for this case:
3381
3382 verify = header_sender/callout=defer_ok
3383

PH
338475. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3385 those file descriptors could be used for SMTP connections. If anything
3386 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3387 could be sent to the SMTP client, causing chaos. The daemon now opens
3388 stdin, stdout, and stderr to /dev/null when it puts itself into the
