PP
22 (Only plugin which currently uses this is kerberos4, which nobody should
23 be using, but we should make it available and other future plugins might
24 conceivably use it, even though it would break NAT; stuff *should* be

209 real issues in debug logging.
210

211PP/32 GnuTLS was always using default tls_require_ciphers, due to a missing

213
3375e053
PP
214PP/33 Added tls_dh_max_bits option, defaulting to current hard-coded limit
215 of NSS, for GnuTLS/NSS interop. Problem root cause diagnosis by
216 Janne Snabb (who went above and beyond: thank you).
217
218PP/34 Validate tls_require_ciphers on startup, since debugging an invalid
219 string otherwise requires a connection and a bunch more work and it's
78e0c7a3

PP
227 GNU libc to support some of the 64-bit stuff, should not lead to

PP
235PP/38 Overhaul DH prime handling, supply RFC-specified DH primes as built

TF
257TF/03 Make the exiwhat support code safe for signals. Previously Exim might
258 lock up or crash if it happened to be inside a call to libc when it
259 got a SIGUSR1 from exiwhat.
260
261 The SIGUSR1 handler appends the current process status to the process
262 log which is later printed by exiwhat. It used to use the general
263 purpose logging code to do this, but several functions it calls are
264 not safe for signals.
265
266 The new output code in the SIGUSR1 handler is specific to the process
267 log, and simple enough that it's easy to inspect for signal safety.
268 Removing some special cases also simplifies the general logging code.
269 Removing the spurious timestamps from the process log simplifies
270 exiwhat.
271
c99ce5c9
TF
272TF/04 Improved ratelimit ACL condition.
273
274 The /noupdate option has been deprecated in favour of /readonly which
275 has clearer semantics. The /leaky, /strict, and /readonly update modes
276 are mutually exclusive. The update mode is no longer included in the
277 database key; it just determines when the database is updated. (This
278 means that when you upgrde Exim will forget old rate measurements.)
279
280 Exim now checks that the per_* options are used with an update mode that
281 makes sense for the current ACL. For example, when Exim is processing a
282 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
283 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
284 must specify per_mail/readonly. If you omit the update mode it defaults to
285 /leaky where that makes sense (as before) or /readonly where required.
286
287 The /noupdate option is now undocumented but still supported for
288 backwards compatibility. It is equivalent to /readonly except that in
289 ACLs where /readonly is required you may specify /leaky/noupdate or
290 /strict/noupdate which are treated the same as /readonly.
291
292 A useful new feature is the /count= option. This is a generalization
293 of the per_byte option, so that you can measure the throughput of other
294 aggregate values. For example, the per_byte option is now equivalent
295 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
296
297 The per_rcpt option has been generalized using the /count= mechanism
298 (though it's more complicated than the per_byte equivalence). When it is
299 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
300 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
301 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
302 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
303 Note that using per_rcpt with a non-readonly update mode in more than
304 one ACL will cause the recipients to be double-counted. (The per_mail
305 and per_byte options don't have this problem.)
306
307 The handling of very low rates has changed slightly. If the computed rate
308 is less than the event's count (usually one) then this event is the first
309 after a long gap. In this case the rate is set to the same as this event's
310 count, so that the first message of a spam run is counted properly.
311
312 The major new feature is a mechanism for counting the rate of unique
313 events. The new per_addr option counts the number of different
314 recipients that someone has sent messages to in the last time period. It
315 behaves like per_rcpt if all the recipient addresses are different, but
316 duplicate recipient addresses do not increase the measured rate. Like
317 the /count= option this is a general mechanism, so the per_addr option
318 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
319 example, measure the rate that a client uses different sender addresses
320 with the options per_mail/unique=$sender_address. There are further
321 details in the main documentation.

401TK/03 SECURITY - DKIM signature header parsing was double-expanded, second
402 time unintentionally subject to list matching rules, letting the header
403 cause arbitrary Exim lookups (of items which can occur in lists, *not*
404 arbitrary string expansion). This allowed for information disclosure.
405
406PP/09 Fix another SIGFPE (x86) in ${eval:...} expansion, this time related to
407 INT_MIN/-1 -- value coerced to INT_MAX.

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

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

893PH/01 Another patch from the Sieve maintainer.
894
6a3bceb1
PH
895PH/02 When an IPv6 address is converted to a string for single-key lookup
896 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
897 dots are used instead of colons so that keys in lsearch files need not
898 contain colons. This was done some time before quoting was made available
899 in lsearch files. However, iplsearch files do require colons in IPv6 keys
900 (notated using the quote facility) so as to distinguish them from IPv4
901 keys. This meant that lookups for IP addresses in host lists did not work
902 for iplsearch lookups.
903
904 This has been fixed by arranging for IPv6 addresses to be expressed with
905 colons if the lookup type is iplsearch. This is not incompatible, because
906 previously such lookups could never work.
907
908 The situation is now rather anomolous, since one *can* have colons in
909 ordinary lsearch keys. However, making the change in all cases is
910 incompatible and would probably break a number of configurations.

MH
915MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
916 conversion specification without a maximum field width, thereby enabling
917 a rogue spamd server to cause a buffer overflow. While nobody in their
918 right mind would setup Exim to query an untrusted spamd server, an
919 attacker that gains access to a server running spamd could potentially
920 exploit this vulnerability to run arbitrary code as the Exim user.

MH
925MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
926 a directory entry by the name of the lookup key. Previously, if a
927 symlink pointed to a non-existing file or a file in a directory that
928 Exim lacked permissions to read, a lookup for a key matching that
929 symlink would fail. Now it is enough that a matching directory entry
930 exists, symlink or not. (Bugzilla 503.)

1007 if a client was not listed at all, or was listed with a value other than

1113PH/29 SMTP synchronization checks are implemented when a command is read -
1114 there is a check that no more input is waiting when there shouldn't be
1115 any. However, for some commands, a delay in an ACL can mean that it is
1116 some time before the response is written. In this time, more input might
1117 arrive, invalidly. So now there are extra checks after an ACL has run for
1118 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1119 pipelining has not been advertised.

1134 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1135 was a macro that became an assignment, so it seemed to work. This has

58eb016e 1192PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1193 the response to the final '.' that terminates a message, but only in the
1194 case where the client has not sent further data following the '.'
1195 (unfortunately, this is allowed). However, in many cases there won't be
1196 any further data because there won't be any more messages to send. A call
1197 to select() can be used: if it shows that the input is "ready", there is
1198 either input waiting, or the socket has been closed. An attempt to read
1199 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1200 would have sent an OK response which the client would never have see.

1208Exim version 4.66
1209-----------------
1210
1211PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1212 fixed by 4.65/MH/01 (is this a record?) are fixed:
1213
1214 (i) An empty string was always treated as zero by the numeric comparison
1215 operators. This behaviour has been restored.
1216
1217 (ii) It is documented that the numeric comparison operators always treat
1218 their arguments as decimal numbers. This was broken in that numbers
1219 starting with 0 were being interpreted as octal.
1220
1221 While fixing these problems I realized that there was another issue that
1222 hadn't been noticed. Values of message_size_limit (both the global option
1223 and the transport option) were treated as octal if they started with 0.
1224 The documentation was vague. These values are now always treated as
1225 decimal, and I will make that clear in the documentation.

1239PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1240 child addresses, Exim now panics and dies. Previously, because the count
1241 is held in a short int, deliveries were likely to be lost. As such a
1242 large number of recipients for a single message is ridiculous
1243 (performance will be very, very poor), I have chosen to impose a limit
1244 rather than extend the field.

1250TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1251 leftover -K file (the existence of which was triggered by #402).
1252 While we were at it, introduced process PID as part of the -K
1253 filename. This should rule out race conditions when creating
1254 these files.

1256TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1257 processing considerably. Previous code took too long for large mails,
1258 triggering a timeout which in turn triggers #401.
1259
1260TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1261 in the DK code in transports.c. sendfile() is not really portable,

1264TF/01 In the add_headers option to the mail command in an Exim filter,

1267 in the field name.

2b1c6e3a
PH
1269PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1270 callout verification, Exim cached a "reject" for the entire domain. This
1271 is correct for most verifications, but it is not correct for a recipient
1272 verification with use_sender or use_postmaster set, because in that case
1273 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1274 case of MAIL FROM:<> rejection from other early rejections (e.g.
1275 rejection of HELO). When verifying a recipient using a non-null MAIL
1276 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1277 Whatever the result of the callout, the value of the domain cache is
1278 left unchanged (for any other kind of callout, getting as far as trying
1279 RCPT means that the domain itself is ok).

1313PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1314 hostname. This is wrong, because it relates to the incoming message (and
1315 probably the interface on which it is arriving) and not to the outgoing
1316 callout (which could be using a different interface). This has been
1317 changed to use the value of the helo_data option from the smtp transport
1318 instead - this is what is used when a message is actually being sent. If
1319 there is no remote transport (possible with a router that sets up host
1320 addresses), $smtp_active_hostname is used.

7befa435 1323 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1324 (a) The code assumed that strncpy() returns a negative number on buffer
1325 overflow, which isn't the case. Replaced with Exim's string_format()
1326 function.
1327 (b) There were several signed/unsigned issues. I just did the minimum
1328 hacking in of casts. There is scope for a larger refactoring.
1329 (c) The code used strcasecmp() which is not a standard C function.
1330 Replaced with Exim's strcmpic() function.
1331 (d) The code set only $1; it now sets $auth1 as well.
1332 (e) A simple test gave the error "authentication client didn't specify
1333 service in request". It would seem that Dovecot has changed its
1334 interface. Fortunately there's a specification; I followed it and
1335 changed what the client sends and it appears to be working now.

1340PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1341 address A is aliased to B and C, where B exists and C does not. Without
1342 -v the output is "A verified" because verification stops after a
1343 successful redirection if more than one address is generated. However,
1344 with -v the child addresses are also verified. Exim was outputting "A
1345 failed to verify" and then showing the successful verification for C,
1346 with its parentage. It now outputs "B failed to verify", showing B's
1347 parentage before showing the successful verification of C.

1350 look up a TXT record in a specific list after matching in a combined
1351 list.
1352
322050c2
PH
1353PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1354 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1355 they consult the DNS. I had assumed they would set it the way they
1356 wanted; and indeed my experiments on Linux seem to show that in some
1357 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1358 To be on the safe side, however, I have now made the interface to
1359 host_find_byname() similar to host_find_bydns(), with an argument
1360 containing the DNS resolver options. The host_find_byname() function now
1361 sets these options at its start, just as host_find_bydns() does. The smtp
1362 transport options dns_qualify_single and dns_search_parents are passed to
1363 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1364 of host_find_byname() use the default settings of RES_DEFNAMES
1365 (qualify_single) but not RES_DNSRCH (search_parents).

1367PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1368 spool_read_header() do less string testing, by means of a preliminary
1369 switch on the second character of optional "-foo" lines. (This is
1370 overdue, caused by the large number of possibilities that now exist.
1371 Originally there were few.) While I was there, I also converted the
1372 str(n)cmp tests so they don't re-test the leading "-" and the first
1373 character, in the hope this might squeeze out yet more improvement.

PH
1375PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1376 flag allowing group syntax was set by the header_syntax check but not
1377 turned off, possible causing trouble later; (2) The flag was not being
1378 set at all for the header_verify test, causing "group"-style headers to
1379 be rejected. I have now set it in this case, and also caused header_
1380 verify to ignore an empty address taken from a group. While doing this, I
1381 came across some other cases where the code for allowing group syntax
1382 while scanning a header line wasn't quite right (mostly, not resetting
1383 the flag correctly in the right place). These bugs could have caused
1384 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1386PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1387 with the "reply" argument non-NULL. The code, however (which originally
1388 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1389 but it didn't always do it. This confused somebody who was copying the
1390 code for some other use. I have removed all the tests.

PH
1392PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1393 feature that was used to support insecure browsers during the U.S. crypto
1394 embargo. It requires special client support, and Exim is probably the
1395 only MTA that supported it -- and would never use it because real RSA is
1396 always available. This code has been removed, because it had the bad
1397 effect of slowing Exim down by computing (never used) parameters for the
1398 RSA_EXPORT functionality.

PH
1400PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1401 authenticator to fail if there's a tab character in the incoming data
1402 (there should never be unless someone is messing about, as it's supposed
1403 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1404 if the connection is using TLS or if the remote IP is the same as the
1405 local IP, and the "valid-client-cert option" if a client certificate has
1406 been verified.

1437
1438PH/30 Exim was sometimes attempting to deliver messages that had suffered
1439 address errors (4xx response to RCPT) over the same connection as other
1440 messages routed to the same hosts. Such deliveries are always "forced",
1441 so retry times are not inspected. This resulted in far too many retries
1442 for the affected addresses. The effect occurred only when there were more
1443 hosts than the hosts_max_try setting in the smtp transport when it had
1444 the 4xx errors. Those hosts that it had tried were not added to the list
1445 of hosts for which the message was waiting, so if all were tried, there
1446 was no problem. Two fixes have been applied:
1447
1448 (i) If there are any address or message errors in an SMTP delivery, none
1449 of the hosts (tried or untried) are now added to the list of hosts
1450 for which the message is waiting, so the message should not be a
1451 candidate for sending over the same connection that was used for a
1452 successful delivery of some other message. This seems entirely
1453 reasonable: after all the message is NOT "waiting for some host".
1454 This is so "obvious" that I'm not sure why it wasn't done
1455 previously. Hope I haven't missed anything, but it can't do any
1456 harm, as the worst effect is to miss an optimization.
1457
1458 (ii) If, despite (i), such a delivery is accidentally attempted, the
1459 routing retry time is respected, so at least it doesn't keep
1460 hammering the server.

PH
1475PH/35 The error "getsockname() failed: connection reset by peer" was being
1476 written to the panic log as well as the main log, but it isn't really
1477 panic-worthy as it just means the connection died rather early on. I have
1478 removed the panic log writing for the ECONNRESET error when getsockname()
1479 fails.
1480
48c7f9e2
PH
1481PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1482 runs only) independently of the message's sender address. This meant
1483 that, if the 4xx error was in fact related to the sender, a different
1484 message to the same recipient with a different sender could confuse
1485 things. In particualar, this can happen when sending to a greylisting
1486 server, but other circumstances could also provoke similar problems.
1487 I have changed the default so that the retry time for these errors is now
1488 based a combination of the sender and recipient addresses. This change
1489 can be overridden by setting address_retry_include_sender=false in the
1490 smtp transport.

1761 tcp-wrappers gives "deny", whereas what one would like would be some
1762 kind of temporary error. A kludge has been added to help with this.
1763 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1764 554 error is used if errno is still zero or contains ENOENT (which occurs
1765 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

1805 code found IPv4 interfaces correctly, but gave incorrect values for the
1806 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1807 that it would not match correctly against @[] and not recognize the IPv6
1808 addresses as local.

1851 autoreply, Exim could try to deliver to a non-existent relative file

1874 (a) Failures to set uid/gid, the current directory, or a process leader
1875 in a subprocess such as that created by queryprogram now generate
1876 suitable debugging ouput when -d is set.

1886 additional section of a DNS packet that returns MX or SRV records.
1887 Instead, it always explicitly searches for A/AAAA records. This avoids
1888 major problems that occur when a DNS server includes only records of one
1889 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1890 fixed another bug: if SRV records were looked up and the corresponding
1891 address records were *not* found in the additional section, the port
1892 values from the SRV records were lost.

1894PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
1902PH/19 When calculating a retry time, Exim used to measure the "time since
1903 failure" by looking at the "first failed" field in the retry record. Now
1904 it does not use this if it is later than than the arrival time of the
1905 message. Instead it uses the arrival time. This makes for better
1906 behaviour in cases where some deliveries succeed, thus re-setting the
1907 "first failed" field. An example is a quota failure for a huge message
1908 when small messages continue to be delivered. Without this change, the
1909 "time since failure" will always be short, possible causing more frequent
1910 delivery attempts for the huge message than are intended.

PH
2007PH/42 The content-scanning code uses fopen() to create files in which to put
2008 message data. Previously it was not paying any attention to the mode of
2009 the files. Exim runs with umask(0) because the rest of the code creates
2010 files with open(), and sets the required mode explicitly. Thus, these
2011 files were ending up world-writeable. This was not a big issue, because,
2012 being within the spool directory, they were not world-accessible. I have
2013 created a function called modefopen, which takes an additional mode
2014 argument. It sets umask(777), creates the file, chmods it to the required
2015 mode, then resets the umask. All the relevant calls to fopen() in the
2016 content scanning code have been changed to use this function.

2027 received. Setting client_ignore_invalid_base64 true ignores these errors.
2028 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2029 they are received. Thus, the responses can be made to depend on the

2051PH/52 Two bugs concerned with error handling when the smtp transport is
2052 used in LMTP mode:
2053
2054 (i) Exim was not creating retry information for temporary errors given
2055 for individual recipients after the DATA command when the smtp transport
2056 was used in LMTP mode. This meant that they could be retried too
2057 frequently, and not timed out correctly.
2058
2059 (ii) Exim was setting the flag that allows error details to be returned
2060 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2061 recipients that were returned after the DATA command.
2062
2063PH/53 This is related to PH/52, but is more general: for any failing address,
2064 when detailed error information was permitted to be returned to the
2065 sender, but the error was temporary, then after the final timeout, only
2066 "retry timeout exceeded" was returned. Now it returns the full error as
2067 well as "retry timeout exceeded".

2137PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2138 function verify_get_ident() calls ip_connect() to connect a socket, but
2139 if the "connect()" function timed out, ip_connect() used to close the
2140 socket. However, verify_get_ident() also closes the socket later, and in
2141 between Exim writes to the log, which may get opened at this point. When
2142 the socket was closed in ip_connect(), the log could get the same file
2143 descriptor number as the socket. This naturally causes chaos. The fix is
2144 not to close the socket in ip_connect(); the socket should be closed by
2145 the function that creates it. There was only one place in the code where
2146 this was missing, in the iplookup router, which I don't think anybody now
2147 uses, but I've fixed it anyway.

2170
2171 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2172 string.
2173
2174 (3) Reset the variables that are obtained from the first argument of
2175 ${prvscheck and used in the second argument before leaving the code,
2176 because their memory is reclaimed, so using them afterwards may do
2177 silly things.
2178
2179 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2180 one (it's much easier than Tom thought :-).

2203PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2204 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2205 not being looked up in the rDNS to get a host name, Exim was showing the
2206 IP address twice in Received: lines, even though the IP addresses were
2207 identical. For example:
2208
2209 Received: from [1.2.3.4] (helo=[1.2.3.4])
2210
2211 However, if the real host name was known, it was omitting the HELO data
2212 if it matched the actual IP address. This has been tidied up so that it
2213 doesn't show the same IP address twice.

2241
2242 Auto-submitted: auto-generated
2243
2244 in the messages that it generates (bounce messages and others, such as
2245 warnings). In the case of bounce messages for non-SMTP mesages, there was
2246 also a typo: it was using "Auto_submitted" (underscore instead of
2247 hyphen). Since every message generated by Exim is necessarily in response
2248 to another message, thes have all been changed to:
2249
2250 Auto-Submitted: auto-replied
2251
2252 in accordance with these statements in the RFC:
2253
2254 The auto-replied keyword:

2305 addresses acquired from the DNS when checking that the found name did
2306 have the original IP as one of its addresses. Since any found IPv6
2307 addresses are likely to be in abbreviated form, the comparison could
2308 fail. Luckily, there already exists a function for doing the comparison
2309 by converting both addresses to binary, so now that is used instead of
2310 the text comparison.

2608 with the definition in sysexits.h (which is #included earlier).
2609 Fortunately, Exim does not actually use EX_OK. The code used to try to
2610 preserve the sysexits.h value, by assumimg that macro definitions were
2611 scanned for macro replacements. I have been disabused of this notion,
2612 so now the code just undefines EX_OK before #including unistd.h.

2617 This seems wrong - if the receiver was accepting one byte at a time it
2618 would take for ever. The timeout is now adjusted when this happens. It
2619 doesn't have to be particularly precise.

2770PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These

2779 data, a new version was generated, as expected. It was only the case of a

2827
2828PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2829 that changes the way the GnuTLS parameters are stored in the cache file.
2830 The new format can be generated externally. For backward compatibility,
2831 if the data in the cache doesn't make sense, Exim assumes it has read an
2832 old-format file, and it generates new data and writes a new file. This
2833 means that you can't go back to an older release without removing the
2834 file.
2835
2836PH/03 A redirect router that has both "unseen" and "one_time" set does not
2837 work if there are any delivery delays because "one_time" forces the
2838 parent to be marked "delivered", so its unseen clone is never tried
2839 again. For this reason, Exim now forbids the simultaneous setting of
2840 these two options.
2841
2842PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2843 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2844 entry if you want to know the details. The fix, however, neglected to
2845 consider the case when local delivery batching is involved. The test for
2846 "previously delivered" was not happening when checking to see if an
2847 address could be batched with a previous (undelivered) one; under
2848 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2849 address.

2854PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2855 header_syntax) but Exim was just ignoring anything given after a slash.
2856 In particular, this caused confusion with an attempt to use "verify =
2857 reverse_host_lookup/defer_ok". An error is now given when options are
2858 supplied for verify items that do not have them. (Maybe reverse_host_
2859 lookup should have a defer_ok option, but that's a different point.)

2861PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2914 the file with the wrong ownership). There was no test for failure of this
2915 fork() call, which would lead to the process getting stuck as it waited
2916 for a non-existent subprocess. Forks do occasionally fail when resources

2924 string after "input=" when read() returned zero. If read() returned -1

2937PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2938 hadn't been configured. The fix is from Juergen Kreileder, who
2939 understands it better than I do:
2940
2941 "Here's what I see happening with three configured cyrus_sasl
2942 authenticators configured (plain, login, cram-md5):
2943
2944 On startup auth_cyrus_sasl_init() gets called for each of these.
2945 This means three calls to sasl_listmech() without a specified mech_list.
2946 => SASL tests which mechs of all available mechs actually work
2947 => three warnings about OTP not working
2948 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2949
2950 With the patch, sasl_listmech() also gets called three times. But now
2951 SASL's mech_list option is set to the server_mech specified in the the
2952 authenticator. Or in other words, the answer from sasl_listmech()
2953 gets limited to just the mech you're testing for (which is different
2954 for each call.)
2955 => the return list contains just 'plain' or 'login', 'cram-md5' or
2956 nothing depending on the value of ob->server_mech.
2957
2958 I've just tested the patch: Authentication still works fine,

PH
3024PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3025 the grounds that routing the same address twice would always produce the
3026 same answer. This might have been true once, but it is certainly no
3027 longer true now. Routing a child address may depend on the previous
3028 routing that produced that child. Some complicated redirection strategies
3029 went wrong when messages had multiple recipients, and made Exim's
3030 behaviour dependent on the order in which the addresses were given.
3031
3032 I have moved the duplicate checking until after the routing is complete.
3033 Exim scans the addresses that are assigned to local and remote
3034 transports, and removes any duplicates. This means that more work will be
3035 done, as duplicates will always all be routed, but duplicates are
3036 presumably rare, so I don't expect this is of any significance.
3037
3038 For deliveries to pipes, files, and autoreplies, the duplicate checking
3039 still happens during the routing process, since they are not going to be

3085 consistency with the overall process timeout, these timeouts are now

3087 there is now a new Boolean option for the pipe transport called

3099A note about Exim versions 4.44 and 4.50
3100----------------------------------------
3101
3102Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3103changes of various kinds. As a consequence, a big documentation update was
3104needed. This delayed the release for rather longer than seemed good, especially
3105in the light of a couple of (minor) security issues. Therefore, the changes
3106that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3107release. So 4.44 and 4.50 are in effect two different branches that both start
3108from 4.43.
3109
3110I have left the 4.50 change log unchanged; it contains all the changes since
31114.43. The change log for 4.44 is below; many of its items are identical to
3112those for 4.50. This seems to be the most sensible way to preserve the
3113historical information.

3157 cached ldap connection that the parent has called unbind on.

PH
315912. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3160 of $address_data from the recipient verification was clobbered by the
3161 sender verification.
3162
316313. The value of address_data from a sender verification is now available in
3164 $sender_address_data in subsequent conditions in the ACL statement.
3165
23c7ff99
PH
316614. Added forbid_sieve_filter and forbid_exim_filter to the redirect router.
3167

PH
316815. Added a new option "connect=<time>" to callout options, to set a different
3169 connection timeout.
3170
926e1192
PH
317116. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3172 was its contents. (It was OK if the option was not defined at all.)
3173
650edc6f
PH
317417. A "Completed" log line is now written for messages that are removed from
3175 the spool by the -Mrm option.
3176
2c7db3f5
PH
317718. New variables $sender_verify_failure and $recipient_verify_failure contain
3178 information about exactly what failed.
3179
3d235903
PH
318019. Added -dd to debug only the daemon process.
3181
7c7ad977
PH
318220. Incorporated Michael Haardt's patch to ldap.c for improving the way it
3183 handles timeouts, both on the server side and network timeouts. Renamed the
3184 CONNECT parameter as NETTIMEOUT (but kept the old name for compatibility).
3185
981756db
PH
318621. The rare case of EHLO->STARTTLS->HELO was setting the protocol to "smtp".
3187 It is now set to "smtps".
3188
d4eb88df
PH
318922. $host_address is now set to the target address during the checking of
3190 ignore_target_hosts.
3191
319223. When checking ignore_target_hosts for an ipliteral router, no host name was
3193 being passed; this would have caused $sender_host_name to have been used if
3194 matching the list had actually called for a host name (not very likely,
3195 since this list is usually IP addresses). A host name is now passed as
3196 "[x.x.x.x]".
3197
7d468ab8
PH
319824. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3199 code that specifies a non-restarting handler (typically sigaction() in
3200 modern systems) in an attempt to fix a rare and obscure crash bug.
3201
320225. Narrowed the window for a race in the daemon that could cause it to ignore
3203 SIGCHLD signals. This is not a major problem, because they are used only to
3204 wake it up if nothing else does.
3205
62c0818f
PH
320626. A malformed maildirsize file could cause Exim to calculate negative values
3207 for the mailbox size or file count. Odd effects could occur as a result.
3208 The maildirsize information is now recalculated if the size or filecount
3209 end up negative.
3210
26034054
PH
321127. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3212 support for a long time. Removed HAVE_SYS_VFS_H.
3213
af66f652
PH
321428. Installed the latest version of exipick from John Jetmore.
3215
90af77f4
PH
321629. In an address list, if the pattern was not a regular expression, an empty
3217 subject address (from a bounce message) matched only if the pattern was an
3218 empty string. Non-empty patterns were not even tested. This was the wrong
3219 because it is perfectly reasonable to use an empty address as part of a
3220 database query. An empty address is now tested by patterns that are
3221 lookups. However, all the other forms of pattern expect the subject to
3222 contain a local part and a domain, and therefore, for them, an empty
3223 address still always fails if the pattern is not itself empty.
3224
d8ef3577
PH
322530. Exim went into a mad DNS loop when attempting to do a callout where the
3226 host was specified on an smtp transport, and looking it up yielded more
3227 than one IP address.
3228
5cb8cbc6
PH
322931. Re-factored the code for checking spool and log partition space into a
3230 function that finds that data and another that does the check. The former
3231 is then used to implement four new variables: $spool_space, $log_space,
3232 $spool_inodes, and $log_inodes.
3233
14702f5b
PH
323432. The RFC2047 encoding function was originally intended for short strings
3235 such as real names; it was not keeping to the 75-character limit for
3236 encoded words that the RFC imposes. It now respects the limit, and
3237 generates multiple encoded words if necessary. To be on the safe side, I
3238 have increased the buffer size for the ${rfc2047: expansion operator from
3239 1024 to 2048 bytes.
3240
063b1e99
PH
324133. It is now permitted to omit both strings after an "if" condition; if the
3242 condition is true, the result is "true". As before, when the second string
3243 is omitted, a false condition yields an empty string. This makes it less
3244 cumbersome to write custom ACL and router conditions.
3245
652e1b65
PH
324634. Failure to deliver a bounce message always caused it to be frozen, even if
3247 there was an errors_to setting on the router. The errors_to setting is now
3248 respected.
3249
6f0c9a4f
PH
325035. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3251 canonical form (fully expanded) before being placed in
3252 $sender_host_address.
3253
33397d19
PH
325436. The table in the code that translates DNS record types into text (T_A to
3255 "A" for instance) was missing entries for NS and CNAME. It is just possible
3256 that this could have caused confusion if both these types were looked up
3257 for the same domain, because the text type is used as part of Exim's
3258 per-process caching. But the chance of anyone hitting this buglet seems
3259 very small.
3260
7bb56e1f
PH
326137. The dnsdb lookup has been extended in a number of ways.
3262
3263 (1) There is a new type, "zns", which walks up the domain tree until it
3264 finds some nameserver records. It should be used with care.
3265
ea3bc19b
PH
3266 (2) There is a new type, "mxh", which is like "mx" except that it returns
3267 just the host names, not the priorities.
3268
3269 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
3270 looked up. The behaviour when one of the lookups defers can be
3271 controlled by a keyword.
7bb56e1f 3272
ea3bc19b 3273 (4) It is now possible to specify the separator character for use when
7bb56e1f 3274 multiple records are returned.
33397d19 3275
0bcb2a0e
PH
327638. The dnslists ACL condition has been extended: it is now possible to supply
3277 a list of IP addresses and/or domains to be looked up in a particular DNS
3278 domain.

PH
328039. Added log_selector=+queue_time_overall.
3281
4e1fde53
PH
328240. When running the queue in the test harness, wait just a tad after forking a
3283 delivery process, to get repeatability of debugging output.
3284
de365ded
PH
328541. Include certificate and key file names in error message when GnuTLS fails
3286 to set them up, because the GnuTLS error message doesn't include the name
3287 of the failing file when there is a problem reading it.
3288
f05da2e8
PH
328942. Allow both -bf and -bF in the same test run.

PH
329143. Did the same fix as 41 above for OpenSSL, which had the same infelicity.
3292
f7b63901
PH
329344. The "Exiscan patch" is now merged into the mainline Exim source.
3294
329545. Sometimes the final signoff response after QUIT could fail to get
3296 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3297 < 0 before doing a fflush(). This bug looks as though it goes back to the
3298 introduction of TLS in release 3.20, but "sometimes" must have been rare
3299 because the tests only now provoked it.
3300

PH
330146. Reset the locale to "C" after calling embedded Perl, in case it was changed
3302 (this can affect the format of dates).
3303
0ec020ea
PH
330447. exim_tidydb, when checking for the continued existence of a message for
3305 which it has found a message-specific retry record, was not finding
3306 messages that were in split spool directories. Consequently, it was
3307 deleting retry records that should have stayed in existence.
3308
b1206957
PH
330948. Steve fixed some bugs in eximstats.
3310
331149. The SPA authentication driver was not abandoning authentication and moving
3312 on to the next authenticator when an expansion was forced to fail,
3313 contradicting the general specification for all authenticators. Instead it
3314 was generating a temporary error. It now behaves as specified.
3315
26dd5a95
PH
331650. The default ordering of permitted cipher suites for GnuTLS was pessimal
3317 (the order specifies the preference for clients). The order is now AES256,
3318 AES128, 3DES, ARCFOUR128.
3319

PH
332051. Small patch to Sieve code - explicitly set From: when generating an
3321 autoreply.
3322
1c5466b9
PH
332352. Exim crashed if a remote delivery caused a very long error message to be
3324 recorded - for instance if somebody sent an entire SpamAssassin report back
3325 as a large number of 550 error lines. This bug was coincidentally fixed by
3326 increasing the size of one of Exim's internal buffers (big_buffer) that
3327 happened as part of the Exiscan merge. However, to be on the safe side, I
3328 have made the code more robust (and fixed the comments that describe what
3329 is going on).
3330
55ee9ee3
PH
333153. Now that there can be additional text after "Completed" in log lines (if
3332 the queue_time_overall log selector is set), a one-byte patch to exigrep
3333 was needed to allow it to recognize "Completed" as not the last thing in
3334 the line.
3335

PH
333654. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3337 patch that reportedly fixes this has been added. I am not expert enough to
3338 create a test for it. This is what the patch creator wrote:
3339
3340 "I found a little strange behaviour of ldap code when working with
3341 Windows 2003 AD Domain, where users was placed in more than one
3342 Organization Units. When I tried to give exim partial DN, the exit code
3343 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3344 But simultaneously result of request was absolutely normal ldap result,
3345 so I produce this patch..."
3346
3295e65b
PH
3347 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3348 REFERENCE, so I have modified the code to exclude the patch when that macro
3349 is not defined.
3350

PH
335155. Some experimental protocols are using DNS PTR records for new purposes. The
3352 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3353 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3354 leaves it alone. Component reversal etc. now happens only for IP addresses.

335957. Double the size of the debug message buffer (to 2048) so that more of very
3360 long debug lines gets shown.
3361
18ce445d
PH
336258. The exicyclog utility now does better if the number of log files to keep
3363 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
3364

PH
336559. Two changes related to the smtp_active_hostname option:
3366
3367 (1) $smtp_active_hostname is now available as a variable.
3368 (2) The default for smtp_banner uses $smtp_active_hostname instead
3369 of $primary_hostname.
3370
b975ba52
PH
337160. The host_aton() function is supposed to be passed a string that is known
3372 to be a valid IP address. However, in the case of IPv6 addresses, it was
3373 not checking this. This is a hostage to fortune. Exim now panics and dies
3374 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3375 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3376 components; fortuitously, this particular loophole had already been fixed
3377 by change 4.50/55 above.
