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
25 using channel bindings instead).

239 real issues in debug logging.
240
5779e6aa
PP
241PP/32 GnuTLS was always using default tls_require_ciphers, due to a missing

243
3375e053
PP
244PP/33 Added tls_dh_max_bits option, defaulting to current hard-coded limit
245 of NSS, for GnuTLS/NSS interop. Problem root cause diagnosis by
246 Janne Snabb (who went above and beyond: thank you).
247
248PP/34 Validate tls_require_ciphers on startup, since debugging an invalid
249 string otherwise requires a connection and a bunch more work and it's
78e0c7a3

b87a6e0e
PP
257 GNU libc to support some of the 64-bit stuff, should not lead to
258 conflicts. Defined before os.h is pulled in, so if a given platform
259 needs to override this, it can.

PP
265PP/38 Overhaul DH prime handling, supply RFC-specified DH primes as built
266 into Exim, default to IKE id 23 from RFC 5114 (2048 bit). Make
267 tls_dhparam take prime identifiers. Also unbreak combination of
268 OpenSSL+DH_params+TLSSNI.

TF
287TF/03 Make the exiwhat support code safe for signals. Previously Exim might
288 lock up or crash if it happened to be inside a call to libc when it
289 got a SIGUSR1 from exiwhat.
290
291 The SIGUSR1 handler appends the current process status to the process
292 log which is later printed by exiwhat. It used to use the general
293 purpose logging code to do this, but several functions it calls are
294 not safe for signals.
295
296 The new output code in the SIGUSR1 handler is specific to the process
297 log, and simple enough that it's easy to inspect for signal safety.
298 Removing some special cases also simplifies the general logging code.
299 Removing the spurious timestamps from the process log simplifies
300 exiwhat.
301
c99ce5c9
TF
302TF/04 Improved ratelimit ACL condition.
303
304 The /noupdate option has been deprecated in favour of /readonly which
305 has clearer semantics. The /leaky, /strict, and /readonly update modes
306 are mutually exclusive. The update mode is no longer included in the
307 database key; it just determines when the database is updated. (This
308 means that when you upgrde Exim will forget old rate measurements.)
309
310 Exim now checks that the per_* options are used with an update mode that
311 makes sense for the current ACL. For example, when Exim is processing a
312 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
313 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
314 must specify per_mail/readonly. If you omit the update mode it defaults to
315 /leaky where that makes sense (as before) or /readonly where required.
316
317 The /noupdate option is now undocumented but still supported for
318 backwards compatibility. It is equivalent to /readonly except that in
319 ACLs where /readonly is required you may specify /leaky/noupdate or
320 /strict/noupdate which are treated the same as /readonly.
321
322 A useful new feature is the /count= option. This is a generalization
323 of the per_byte option, so that you can measure the throughput of other
324 aggregate values. For example, the per_byte option is now equivalent
325 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
326
327 The per_rcpt option has been generalized using the /count= mechanism
328 (though it's more complicated than the per_byte equivalence). When it is
329 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
330 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
331 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
332 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
333 Note that using per_rcpt with a non-readonly update mode in more than
334 one ACL will cause the recipients to be double-counted. (The per_mail
335 and per_byte options don't have this problem.)
336
337 The handling of very low rates has changed slightly. If the computed rate
338 is less than the event's count (usually one) then this event is the first
339 after a long gap. In this case the rate is set to the same as this event's
340 count, so that the first message of a spam run is counted properly.
341
342 The major new feature is a mechanism for counting the rate of unique
343 events. The new per_addr option counts the number of different
344 recipients that someone has sent messages to in the last time period. It
345 behaves like per_rcpt if all the recipient addresses are different, but
346 duplicate recipient addresses do not increase the measured rate. Like
347 the /count= option this is a general mechanism, so the per_addr option
348 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
349 example, measure the rate that a client uses different sender addresses
350 with the options per_mail/unique=$sender_address. There are further
351 details in the main documentation.

901 Note to Michael Haardt: I had to rename some vars in sieve.c. They
902 were called 'true' and it seems that C99 defines that as a reserved
903 keyword to be used with 'bool' variable types. That means you could
904 not include C99-style headers which use bools without triggering

923PH/01 Another patch from the Sieve maintainer.
924
6a3bceb1
PH
925PH/02 When an IPv6 address is converted to a string for single-key lookup
926 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
927 dots are used instead of colons so that keys in lsearch files need not
928 contain colons. This was done some time before quoting was made available
929 in lsearch files. However, iplsearch files do require colons in IPv6 keys
930 (notated using the quote facility) so as to distinguish them from IPv4
931 keys. This meant that lookups for IP addresses in host lists did not work
932 for iplsearch lookups.
933
934 This has been fixed by arranging for IPv6 addresses to be expressed with
935 colons if the lookup type is iplsearch. This is not incompatible, because
936 previously such lookups could never work.
937
938 The situation is now rather anomolous, since one *can* have colons in
939 ordinary lsearch keys. However, making the change in all cases is
940 incompatible and would probably break a number of configurations.

945MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
946 conversion specification without a maximum field width, thereby enabling
947 a rogue spamd server to cause a buffer overflow. While nobody in their
948 right mind would setup Exim to query an untrusted spamd server, an
949 attacker that gains access to a server running spamd could potentially
950 exploit this vulnerability to run arbitrary code as the Exim user.

MH
955MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
956 a directory entry by the name of the lookup key. Previously, if a
957 symlink pointed to a non-existing file or a file in a directory that
958 Exim lacked permissions to read, a lookup for a key matching that
959 symlink would fail. Now it is enough that a matching directory entry
960 exists, symlink or not. (Bugzilla 503.)

1037 if a client was not listed at all, or was listed with a value other than

1143PH/29 SMTP synchronization checks are implemented when a command is read -
1144 there is a check that no more input is waiting when there shouldn't be

1146 some time before the response is written. In this time, more input might
1147 arrive, invalidly. So now there are extra checks after an ACL has run for
1148 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1149 pipelining has not been advertised.

1195PH/40 When Exim receives a message, it writes the login name, uid, and gid of
1196 whoever called Exim into the -H file. In the case of the daemon it was
1197 behaving confusingly. When first started, it used values for whoever
1198 started the daemon, but after a SIGHUP it used the Exim user (because it
1199 calls itself on a restart). I have changed the code so that it now always
1200 uses the Exim user.

1202PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a

1204 sender address), and a DATA command is nevertheless sent (as can happen
1205 with PIPELINING or a stupid MUA), the error message that was given to the
1206 RCPT commands is included in the rejection of the DATA command. This is
1207 intended to be helpful for MUAs that show only the final error to their
1208 users.

58eb016e 1222PH/44 I found a way to check for a TCP/IP connection going away before sending

PH
1223 the response to the final '.' that terminates a message, but only in the
1224 case where the client has not sent further data following the '.'
1225 (unfortunately, this is allowed). However, in many cases there won't be
1226 any further data because there won't be any more messages to send. A call
1227 to select() can be used: if it shows that the input is "ready", there is
1228 either input waiting, or the socket has been closed. An attempt to read
1229 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1230 would have sent an OK response which the client would never have see.

1240
1241PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1242 fixed by 4.65/MH/01 (is this a record?) are fixed:
1243
1244 (i) An empty string was always treated as zero by the numeric comparison
1245 operators. This behaviour has been restored.
1246
1247 (ii) It is documented that the numeric comparison operators always treat
1248 their arguments as decimal numbers. This was broken in that numbers
1249 starting with 0 were being interpreted as octal.
1250
1251 While fixing these problems I realized that there was another issue that
1252 hadn't been noticed. Values of message_size_limit (both the global option
1253 and the transport option) were treated as octal if they started with 0.
1254 The documentation was vague. These values are now always treated as
1255 decimal, and I will make that clear in the documentation.

1269PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1270 child addresses, Exim now panics and dies. Previously, because the count
1271 is held in a short int, deliveries were likely to be lost. As such a
1272 large number of recipients for a single message is ridiculous
1273 (performance will be very, very poor), I have chosen to impose a limit
1274 rather than extend the field.

PH
1299PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1300 callout verification, Exim cached a "reject" for the entire domain. This
1301 is correct for most verifications, but it is not correct for a recipient
1302 verification with use_sender or use_postmaster set, because in that case
1303 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1304 case of MAIL FROM:<> rejection from other early rejections (e.g.
1305 rejection of HELO). When verifying a recipient using a non-null MAIL
1306 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1307 Whatever the result of the callout, the value of the domain cache is
1308 left unchanged (for any other kind of callout, getting as far as trying
1309 RCPT means that the domain itself is ok).

1343PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1345 probably the interface on which it is arriving) and not to the outgoing
1346 callout (which could be using a different interface). This has been
1347 changed to use the value of the helo_data option from the smtp transport
1348 instead - this is what is used when a message is actually being sent. If
1349 there is no remote transport (possible with a router that sets up host
1350 addresses), $smtp_active_hostname is used.

14aa5a05
PH
1354 (a) The code assumed that strncpy() returns a negative number on buffer
1355 overflow, which isn't the case. Replaced with Exim's string_format()
1356 function.
1357 (b) There were several signed/unsigned issues. I just did the minimum
1358 hacking in of casts. There is scope for a larger refactoring.
1359 (c) The code used strcasecmp() which is not a standard C function.
1360 Replaced with Exim's strcmpic() function.
1361 (d) The code set only $1; it now sets $auth1 as well.
1362 (e) A simple test gave the error "authentication client didn't specify
1363 service in request". It would seem that Dovecot has changed its
1364 interface. Fortunately there's a specification; I followed it and
1365 changed what the client sends and it appears to be working now.

1371 address A is aliased to B and C, where B exists and C does not. Without
1372 -v the output is "A verified" because verification stops after a
1373 successful redirection if more than one address is generated. However,
1374 with -v the child addresses are also verified. Exim was outputting "A
1375 failed to verify" and then showing the successful verification for C,
1376 with its parentage. It now outputs "B failed to verify", showing B's
1377 parentage before showing the successful verification of C.

1382
322050c2
PH
1383PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1384 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1385 they consult the DNS. I had assumed they would set it the way they
1386 wanted; and indeed my experiments on Linux seem to show that in some
1387 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1388 To be on the safe side, however, I have now made the interface to
1389 host_find_byname() similar to host_find_bydns(), with an argument
1390 containing the DNS resolver options. The host_find_byname() function now
1391 sets these options at its start, just as host_find_bydns() does. The smtp
1392 transport options dns_qualify_single and dns_search_parents are passed to
1393 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1394 of host_find_byname() use the default settings of RES_DEFNAMES
1395 (qualify_single) but not RES_DNSRCH (search_parents).

1398 spool_read_header() do less string testing, by means of a preliminary
1399 switch on the second character of optional "-foo" lines. (This is
1400 overdue, caused by the large number of possibilities that now exist.
1401 Originally there were few.) While I was there, I also converted the
1402 str(n)cmp tests so they don't re-test the leading "-" and the first
1403 character, in the hope this might squeeze out yet more improvement.

1405PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1406 flag allowing group syntax was set by the header_syntax check but not
1407 turned off, possible causing trouble later; (2) The flag was not being
1408 set at all for the header_verify test, causing "group"-style headers to
1409 be rejected. I have now set it in this case, and also caused header_
1410 verify to ignore an empty address taken from a group. While doing this, I
1411 came across some other cases where the code for allowing group syntax
1412 while scanning a header line wasn't quite right (mostly, not resetting
1413 the flag correctly in the right place). These bugs could have caused
1414 trouble for malformed header lines. I hope it is now all correct.

PH
1416PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1417 with the "reply" argument non-NULL. The code, however (which originally
1418 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1419 but it didn't always do it. This confused somebody who was copying the
1420 code for some other use. I have removed all the tests.

PH
1422PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1423 feature that was used to support insecure browsers during the U.S. crypto
1424 embargo. It requires special client support, and Exim is probably the
1425 only MTA that supported it -- and would never use it because real RSA is
1426 always available. This code has been removed, because it had the bad
1427 effect of slowing Exim down by computing (never used) parameters for the
1428 RSA_EXPORT functionality.

1431 authenticator to fail if there's a tab character in the incoming data
1432 (there should never be unless someone is messing about, as it's supposed
1433 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1434 if the connection is using TLS or if the remote IP is the same as the
1435 local IP, and the "valid-client-cert option" if a client certificate has
1436 been verified.

1467
1468PH/30 Exim was sometimes attempting to deliver messages that had suffered
1469 address errors (4xx response to RCPT) over the same connection as other
1470 messages routed to the same hosts. Such deliveries are always "forced",
1471 so retry times are not inspected. This resulted in far too many retries
1472 for the affected addresses. The effect occurred only when there were more
1473 hosts than the hosts_max_try setting in the smtp transport when it had
1474 the 4xx errors. Those hosts that it had tried were not added to the list
1475 of hosts for which the message was waiting, so if all were tried, there
1476 was no problem. Two fixes have been applied:
1477
1478 (i) If there are any address or message errors in an SMTP delivery, none
1479 of the hosts (tried or untried) are now added to the list of hosts
1480 for which the message is waiting, so the message should not be a
1481 candidate for sending over the same connection that was used for a
1482 successful delivery of some other message. This seems entirely
1483 reasonable: after all the message is NOT "waiting for some host".
1484 This is so "obvious" that I'm not sure why it wasn't done
1485 previously. Hope I haven't missed anything, but it can't do any
1486 harm, as the worst effect is to miss an optimization.
1487
1488 (ii) If, despite (i), such a delivery is accidentally attempted, the
1489 routing retry time is respected, so at least it doesn't keep
1490 hammering the server.

1505PH/35 The error "getsockname() failed: connection reset by peer" was being
1506 written to the panic log as well as the main log, but it isn't really

1508 removed the panic log writing for the ECONNRESET error when getsockname()
1509 fails.
1510
48c7f9e2
PH
1511PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1512 runs only) independently of the message's sender address. This meant
1513 that, if the 4xx error was in fact related to the sender, a different
1514 message to the same recipient with a different sender could confuse
1515 things. In particualar, this can happen when sending to a greylisting
1516 server, but other circumstances could also provoke similar problems.
1517 I have changed the default so that the retry time for these errors is now
1518 based a combination of the sender and recipient addresses. This change
1519 can be overridden by setting address_retry_include_sender=false in the
1520 smtp transport.

1788PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

1790 Unfortunately, if there is a major crisis, such as a disk failure,
1791 tcp-wrappers gives "deny", whereas what one would like would be some
1792 kind of temporary error. A kludge has been added to help with this.
1793 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1794 554 error is used if errno is still zero or contains ENOENT (which occurs
1795 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1796 451 error is used.

1832PH/01 The code for finding all the local interface addresses on a FreeBSD
1833 system running IPv6 was broken. This may well have applied to all BSD
1834 systems, as well as to others that have similar system calls. The broken
1835 code found IPv4 interfaces correctly, but gave incorrect values for the
1836 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1837 that it would not match correctly against @[] and not recognize the IPv6
1838 addresses as local.

1881 autoreply, Exim could try to deliver to a non-existent relative file
1882 name, causing unrelated and misleading errors. What now happens is that

1904 (a) Failures to set uid/gid, the current directory, or a process leader
1905 in a subprocess such as that created by queryprogram now generate
1906 suitable debugging ouput when -d is set.

1910 the subprocess without attempting to change uid/gid.

1916 additional section of a DNS packet that returns MX or SRV records.
1917 Instead, it always explicitly searches for A/AAAA records. This avoids
1918 major problems that occur when a DNS server includes only records of one
1919 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1920 fixed another bug: if SRV records were looked up and the corresponding
1921 address records were *not* found in the additional section, the port
1922 values from the SRV records were lost.

1924PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
1932PH/19 When calculating a retry time, Exim used to measure the "time since
1933 failure" by looking at the "first failed" field in the retry record. Now
1934 it does not use this if it is later than than the arrival time of the
1935 message. Instead it uses the arrival time. This makes for better
1936 behaviour in cases where some deliveries succeed, thus re-setting the
1937 "first failed" field. An example is a quota failure for a huge message
1938 when small messages continue to be delivered. Without this change, the
1939 "time since failure" will always be short, possible causing more frequent
1940 delivery attempts for the huge message than are intended.

2037PH/42 The content-scanning code uses fopen() to create files in which to put
2038 message data. Previously it was not paying any attention to the mode of
2039 the files. Exim runs with umask(0) because the rest of the code creates
2040 files with open(), and sets the required mode explicitly. Thus, these
2041 files were ending up world-writeable. This was not a big issue, because,
2042 being within the spool directory, they were not world-accessible. I have
2043 created a function called modefopen, which takes an additional mode
2044 argument. It sets umask(777), creates the file, chmods it to the required
2045 mode, then resets the umask. All the relevant calls to fopen() in the

2083
2084 (i) Exim was not creating retry information for temporary errors given
2085 for individual recipients after the DATA command when the smtp transport
2086 was used in LMTP mode. This meant that they could be retried too
2087 frequently, and not timed out correctly.
2088
2089 (ii) Exim was setting the flag that allows error details to be returned
2090 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2091 recipients that were returned after the DATA command.
2092
2093PH/53 This is related to PH/52, but is more general: for any failing address,
2094 when detailed error information was permitted to be returned to the
2095 sender, but the error was temporary, then after the final timeout, only

2167PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2168 function verify_get_ident() calls ip_connect() to connect a socket, but
2169 if the "connect()" function timed out, ip_connect() used to close the
2170 socket. However, verify_get_ident() also closes the socket later, and in
2171 between Exim writes to the log, which may get opened at this point. When
2172 the socket was closed in ip_connect(), the log could get the same file
2173 descriptor number as the socket. This naturally causes chaos. The fix is
2174 not to close the socket in ip_connect(); the socket should be closed by
2175 the function that creates it. There was only one place in the code where
2176 this was missing, in the iplookup router, which I don't think anybody now
2177 uses, but I've fixed it anyway.

2203
2204 (3) Reset the variables that are obtained from the first argument of
2205 ${prvscheck and used in the second argument before leaving the code,
2206 because their memory is reclaimed, so using them afterwards may do
2207 silly things.

2209 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2210 one (it's much easier than Tom thought :-).

2234 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2235 not being looked up in the rDNS to get a host name, Exim was showing the
2236 IP address twice in Received: lines, even though the IP addresses were
2237 identical. For example:
2238
2239 Received: from [1.2.3.4] (helo=[1.2.3.4])
2240
2241 However, if the real host name was known, it was omitting the HELO data

2243 doesn't show the same IP address twice.

2335 addresses acquired from the DNS when checking that the found name did
2336 have the original IP as one of its addresses. Since any found IPv6
2337 addresses are likely to be in abbreviated form, the comparison could
2338 fail. Luckily, there already exists a function for doing the comparison
2339 by converting both addresses to binary, so now that is used instead of

2638 with the definition in sysexits.h (which is #included earlier).
2639 Fortunately, Exim does not actually use EX_OK. The code used to try to
2640 preserve the sysexits.h value, by assumimg that macro definitions were
2641 scanned for macro replacements. I have been disabused of this notion,

2647 This seems wrong - if the receiver was accepting one byte at a time it
2648 would take for ever. The timeout is now adjusted when this happens. It
2649 doesn't have to be particularly precise.

2788 read the rcpt_include_affixes from the non-existent transport. Now it
2789 just assumes that the setting of that option is false. This bug was

2857
2858PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2859 that changes the way the GnuTLS parameters are stored in the cache file.
2860 The new format can be generated externally. For backward compatibility,
2861 if the data in the cache doesn't make sense, Exim assumes it has read an
2862 old-format file, and it generates new data and writes a new file. This
2863 means that you can't go back to an older release without removing the
2864 file.
2865
2866PH/03 A redirect router that has both "unseen" and "one_time" set does not
2867 work if there are any delivery delays because "one_time" forces the
2868 parent to be marked "delivered", so its unseen clone is never tried
2869 again. For this reason, Exim now forbids the simultaneous setting of
2870 these two options.
2871
2872PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2873 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2874 entry if you want to know the details. The fix, however, neglected to
2875 consider the case when local delivery batching is involved. The test for
2876 "previously delivered" was not happening when checking to see if an
2877 address could be batched with a previous (undelivered) one; under
2878 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2879 address.

2881PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2883
2884PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2885 header_syntax) but Exim was just ignoring anything given after a slash.
2886 In particular, this caused confusion with an attempt to use "verify =
2887 reverse_host_lookup/defer_ok". An error is now given when options are
2888 supplied for verify items that do not have them. (Maybe reverse_host_
2889 lookup should have a defer_ok option, but that's a different point.)
2890
2891PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2944 the file with the wrong ownership). There was no test for failure of this
2945 fork() call, which would lead to the process getting stuck as it waited
2946 for a non-existent subprocess. Forks do occasionally fail when resources
2947 run out. I reviewed all the other calls to fork(); they all seem to check

2953 the result was a log entry for a synchronization error with an empty
2954 string after "input=" when read() returned zero. If read() returned -1

PH
2967PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2968 hadn't been configured. The fix is from Juergen Kreileder, who
2969 understands it better than I do:
2970
2971 "Here's what I see happening with three configured cyrus_sasl
2972 authenticators configured (plain, login, cram-md5):
2973
2974 On startup auth_cyrus_sasl_init() gets called for each of these.
2975 This means three calls to sasl_listmech() without a specified mech_list.
2976 => SASL tests which mechs of all available mechs actually work
2977 => three warnings about OTP not working
2978 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2979
2980 With the patch, sasl_listmech() also gets called three times. But now
2981 SASL's mech_list option is set to the server_mech specified in the the
2982 authenticator. Or in other words, the answer from sasl_listmech()
2983 gets limited to just the mech you're testing for (which is different
2984 for each call.)
2985 => the return list contains just 'plain' or 'login', 'cram-md5' or
2986 nothing depending on the value of ob->server_mech.
2987
2988 I've just tested the patch: Authentication still works fine,
2989 unavailable mechs specified in the exim configuration are still
2990 caught, and the auth.log warnings about OTP are gone."

PH
3054PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3055 the grounds that routing the same address twice would always produce the
3056 same answer. This might have been true once, but it is certainly no
3057 longer true now. Routing a child address may depend on the previous
3058 routing that produced that child. Some complicated redirection strategies
3059 went wrong when messages had multiple recipients, and made Exim's
3060 behaviour dependent on the order in which the addresses were given.
3061
3062 I have moved the duplicate checking until after the routing is complete.
3063 Exim scans the addresses that are assigned to local and remote
3064 transports, and removes any duplicates. This means that more work will be
3065 done, as duplicates will always all be routed, but duplicates are
3066 presumably rare, so I don't expect this is of any significance.
3067
3068 For deliveries to pipes, files, and autoreplies, the duplicate checking
3069 still happens during the routing process, since they are not going to be
3070 routed further.

3115 consistency with the overall process timeout, these timeouts are now
3116 treated as errors, giving rise to delivery failures by default. However,
3117 there is now a new Boolean option for the pipe transport called

3129A note about Exim versions 4.44 and 4.50
3130----------------------------------------
3131
3132Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3133changes of various kinds. As a consequence, a big documentation update was
3134needed. This delayed the release for rather longer than seemed good, especially
3135in the light of a couple of (minor) security issues. Therefore, the changes
3136that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3137release. So 4.44 and 4.50 are in effect two different branches that both start
3138from 4.43.
3139
3140I have left the 4.50 change log unchanged; it contains all the changes since
31414.43. The change log for 4.44 is below; many of its items are identical to
3142those for 4.50. This seems to be the most sensible way to preserve the
3143historical information.

3161 5. There are several places where Exim runs a non-Exim command in a
3162 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3163 was being done only for the command run by the queryprogram router. It is
3164 now done for all such subprocesses. The other cases are: ${run, transport
3165 filters, and the commands run by the lmtp and pipe transports.

PH
3167 6. Added CONFIGURE_GROUP build-time option.
3168
3169 7. Some older OS have a limit of 256 on the maximum number of file
3170 descriptors. Exim was using setrlimit() to set 1000 as a large value
3171 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3172 systems. I've change it so that if it can't get 1000, it tries for 256.

3174 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3175 was an oversight, and furthermore, ever since the addition of extra
3176 controls (e.g. 4.43/32), the checks on when to allow different forms of
3177 "control" were broken. There should now be diagnostics for all cases when a
3178 control that does not make sense is encountered.

PH
3180 9. Added the /retain_sender option to "control=submission".

PH
318411. Tidy the search cache before the fork to do a delivery from a message
3185 received from the command line. Otherwise the child will trigger a lookup
3186 failure and thereby defer the delivery if it tries to use (for example) a
3187 cached ldap connection that the parent has called unbind on.
3188

PH
318912. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3190 of $address_data from the recipient verification was clobbered by the
3191 sender verification.
3192
319313. The value of address_data from a sender verification is now available in
3194 $sender_address_data in subsequent conditions in the ACL statement.

PH
319614. Added forbid_sieve_filter and forbid_exim_filter to the redirect router.

319815. Added a new option "connect=<time>" to callout options, to set a different
3199 connection timeout.

PH
320116. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3202 was its contents. (It was OK if the option was not defined at all.)

PH
320417. A "Completed" log line is now written for messages that are removed from
3205 the spool by the -Mrm option.

321019. Added -dd to debug only the daemon process.

PH
321220. Incorporated Michael Haardt's patch to ldap.c for improving the way it
3213 handles timeouts, both on the server side and network timeouts. Renamed the
3214 CONNECT parameter as NETTIMEOUT (but kept the old name for compatibility).

321621. The rare case of EHLO->STARTTLS->HELO was setting the protocol to "smtp".
3217 It is now set to "smtps".

PH
321922. $host_address is now set to the target address during the checking of
3220 ignore_target_hosts.
3221
322223. When checking ignore_target_hosts for an ipliteral router, no host name was
3223 being passed; this would have caused $sender_host_name to have been used if
3224 matching the list had actually called for a host name (not very likely,
3225 since this list is usually IP addresses). A host name is now passed as
3226 "[x.x.x.x]".
3227
7d468ab8
PH
322824. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3229 code that specifies a non-restarting handler (typically sigaction() in
3230 modern systems) in an attempt to fix a rare and obscure crash bug.
3231
323225. Narrowed the window for a race in the daemon that could cause it to ignore
3233 SIGCHLD signals. This is not a major problem, because they are used only to
3234 wake it up if nothing else does.
3235
62c0818f
PH
323626. A malformed maildirsize file could cause Exim to calculate negative values
3237 for the mailbox size or file count. Odd effects could occur as a result.
3238 The maildirsize information is now recalculated if the size or filecount
3239 end up negative.
3240

PH
324127. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3242 support for a long time. Removed HAVE_SYS_VFS_H.

PH
324629. In an address list, if the pattern was not a regular expression, an empty
3247 subject address (from a bounce message) matched only if the pattern was an
3248 empty string. Non-empty patterns were not even tested. This was the wrong
3249 because it is perfectly reasonable to use an empty address as part of a
3250 database query. An empty address is now tested by patterns that are
3251 lookups. However, all the other forms of pattern expect the subject to
3252 contain a local part and a domain, and therefore, for them, an empty
3253 address still always fails if the pattern is not itself empty.

PH
325530. Exim went into a mad DNS loop when attempting to do a callout where the
3256 host was specified on an smtp transport, and looking it up yielded more
3257 than one IP address.
3258

PH
325931. Re-factored the code for checking spool and log partition space into a
3260 function that finds that data and another that does the check. The former
3261 is then used to implement four new variables: $spool_space, $log_space,
3262 $spool_inodes, and $log_inodes.

PH
326432. The RFC2047 encoding function was originally intended for short strings
3265 such as real names; it was not keeping to the 75-character limit for
3266 encoded words that the RFC imposes. It now respects the limit, and
3267 generates multiple encoded words if necessary. To be on the safe side, I
3268 have increased the buffer size for the ${rfc2047: expansion operator from
3269 1024 to 2048 bytes.
3270

PH
327133. It is now permitted to omit both strings after an "if" condition; if the
3272 condition is true, the result is "true". As before, when the second string
3273 is omitted, a false condition yields an empty string. This makes it less
3274 cumbersome to write custom ACL and router conditions.
3275
652e1b65
PH
327634. Failure to deliver a bounce message always caused it to be frozen, even if
3277 there was an errors_to setting on the router. The errors_to setting is now
3278 respected.
3279

PH
328035. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3281 canonical form (fully expanded) before being placed in
3282 $sender_host_address.

PH
328436. The table in the code that translates DNS record types into text (T_A to
3285 "A" for instance) was missing entries for NS and CNAME. It is just possible
3286 that this could have caused confusion if both these types were looked up
3287 for the same domain, because the text type is used as part of Exim's
3288 per-process caching. But the chance of anyone hitting this buglet seems
3289 very small.
3290

PH
329137. The dnsdb lookup has been extended in a number of ways.
3292
3293 (1) There is a new type, "zns", which walks up the domain tree until it
3294 finds some nameserver records. It should be used with care.
3295
ea3bc19b
PH
3296 (2) There is a new type, "mxh", which is like "mx" except that it returns
3297 just the host names, not the priorities.
3298
3299 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
3300 looked up. The behaviour when one of the lookups defers can be
3301 controlled by a keyword.
7bb56e1f 3302
ea3bc19b 3303 (4) It is now possible to specify the separator character for use when
7bb56e1f 3304 multiple records are returned.
33397d19 3305
0bcb2a0e
PH
330638. The dnslists ACL condition has been extended: it is now possible to supply
3307 a list of IP addresses and/or domains to be looked up in a particular DNS
3308 domain.

331039. Added log_selector=+queue_time_overall.

PH
331240. When running the queue in the test harness, wait just a tad after forking a
3313 delivery process, to get repeatability of debugging output.

PH
331541. Include certificate and key file names in error message when GnuTLS fails
3316 to set them up, because the GnuTLS error message doesn't include the name
3317 of the failing file when there is a problem reading it.
3318

331942. Allow both -bf and -bF in the same test run.

PH
332344. The "Exiscan patch" is now merged into the mainline Exim source.
3324
332545. Sometimes the final signoff response after QUIT could fail to get
3326 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3327 < 0 before doing a fflush(). This bug looks as though it goes back to the
3328 introduction of TLS in release 3.20, but "sometimes" must have been rare
3329 because the tests only now provoked it.

333146. Reset the locale to "C" after calling embedded Perl, in case it was changed
3332 (this can affect the format of dates).

PH
333447. exim_tidydb, when checking for the continued existence of a message for
3335 which it has found a message-specific retry record, was not finding
3336 messages that were in split spool directories. Consequently, it was
3337 deleting retry records that should have stayed in existence.

PH
333948. Steve fixed some bugs in eximstats.
3340
334149. The SPA authentication driver was not abandoning authentication and moving
3342 on to the next authenticator when an expansion was forced to fail,
3343 contradicting the general specification for all authenticators. Instead it
3344 was generating a temporary error. It now behaves as specified.
3345

PH
334650. The default ordering of permitted cipher suites for GnuTLS was pessimal
3347 (the order specifies the preference for clients). The order is now AES256,
3348 AES128, 3DES, ARCFOUR128.

335051. Small patch to Sieve code - explicitly set From: when generating an

PH
335352. Exim crashed if a remote delivery caused a very long error message to be
3354 recorded - for instance if somebody sent an entire SpamAssassin report back
3355 as a large number of 550 error lines. This bug was coincidentally fixed by
3356 increasing the size of one of Exim's internal buffers (big_buffer) that
3357 happened as part of the Exiscan merge. However, to be on the safe side, I
3358 have made the code more robust (and fixed the comments that describe what
3359 is going on).
3360

PH
336153. Now that there can be additional text after "Completed" in log lines (if
3362 the queue_time_overall log selector is set), a one-byte patch to exigrep
3363 was needed to allow it to recognize "Completed" as not the last thing in
3364 the line.

PH
336654. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3367 patch that reportedly fixes this has been added. I am not expert enough to
3368 create a test for it. This is what the patch creator wrote:
3369
3370 "I found a little strange behaviour of ldap code when working with
3371 Windows 2003 AD Domain, where users was placed in more than one
3372 Organization Units. When I tried to give exim partial DN, the exit code
3373 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3374 But simultaneously result of request was absolutely normal ldap result,
3375 so I produce this patch..."
3376
3295e65b
PH
3377 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3378 REFERENCE, so I have modified the code to exclude the patch when that macro
3379 is not defined.

338155. Some experimental protocols are using DNS PTR records for new purposes. The
3382 keys for these records are domain names, not reversed IP addresses. The
