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

PP
231PP/31 %D in printf continues to cause issues (-Wformat=security), so for

233 As part of this, removing so much warning spew let me fix some minor
234 real issues in debug logging.
235
5779e6aa
PP
236PP/32 GnuTLS was always using default tls_require_ciphers, due to a missing
237 assignment on my part. Fixed.
238
3375e053
PP
239PP/33 Added tls_dh_max_bits option, defaulting to current hard-coded limit
240 of NSS, for GnuTLS/NSS interop. Problem root cause diagnosis by
241 Janne Snabb (who went above and beyond: thank you).
242
243PP/34 Validate tls_require_ciphers on startup, since debugging an invalid
244 string otherwise requires a connection and a bunch more work and it's
78e0c7a3
PP
245 relatively easy to get wrong. Should also expose TLS library linkage
246 problems.

b87a6e0e
PP
252 GNU libc to support some of the 64-bit stuff, should not lead to
253 conflicts. Defined before os.h is pulled in, so if a given platform
254 needs to override this, it can.
255
16880d1a
PP
256PP/37 Unbreak Cyrus SASL auth: SSF retrieval was incorrect, Exim thought
257 protection layer was required, which is not implemented.

259
a799883d
PP
260PP/38 Overhaul DH prime handling, supply RFC-specified DH primes as built
261 into Exim, default to IKE id 23 from RFC 5114 (2048 bit). Make
262 tls_dhparam take prime identifiers. Also unbreak combination of
263 OpenSSL+DH_params+TLSSNI.

280 when unlink() failed. See also change 4.74-TF/03.
281
921b12ca
TF
282TF/03 Make the exiwhat support code safe for signals. Previously Exim might
283 lock up or crash if it happened to be inside a call to libc when it
284 got a SIGUSR1 from exiwhat.
285
286 The SIGUSR1 handler appends the current process status to the process
287 log which is later printed by exiwhat. It used to use the general
288 purpose logging code to do this, but several functions it calls are
289 not safe for signals.
290
291 The new output code in the SIGUSR1 handler is specific to the process
292 log, and simple enough that it's easy to inspect for signal safety.
293 Removing some special cases also simplifies the general logging code.
294 Removing the spurious timestamps from the process log simplifies
295 exiwhat.
296

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

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

PH
920PH/02 When an IPv6 address is converted to a string for single-key lookup
921 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
922 dots are used instead of colons so that keys in lsearch files need not
923 contain colons. This was done some time before quoting was made available
924 in lsearch files. However, iplsearch files do require colons in IPv6 keys
925 (notated using the quote facility) so as to distinguish them from IPv4
926 keys. This meant that lookups for IP addresses in host lists did not work
927 for iplsearch lookups.
928
929 This has been fixed by arranging for IPv6 addresses to be expressed with
930 colons if the lookup type is iplsearch. This is not incompatible, because
931 previously such lookups could never work.
932
933 The situation is now rather anomolous, since one *can* have colons in
934 ordinary lsearch keys. However, making the change in all cases is
935 incompatible and would probably break a number of configurations.

940MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
941 conversion specification without a maximum field width, thereby enabling
942 a rogue spamd server to cause a buffer overflow. While nobody in their
943 right mind would setup Exim to query an untrusted spamd server, an
944 attacker that gains access to a server running spamd could potentially
945 exploit this vulnerability to run arbitrary code as the Exim user.

950MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
951 a directory entry by the name of the lookup key. Previously, if a
952 symlink pointed to a non-existing file or a file in a directory that
953 Exim lacked permissions to read, a lookup for a key matching that
954 symlink would fail. Now it is enough that a matching directory entry
955 exists, symlink or not. (Bugzilla 503.)

1138PH/29 SMTP synchronization checks are implemented when a command is read -
1139 there is a check that no more input is waiting when there shouldn't be

1141 some time before the response is written. In this time, more input might
1142 arrive, invalidly. So now there are extra checks after an ACL has run for
1143 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1144 pipelining has not been advertised.

1190PH/40 When Exim receives a message, it writes the login name, uid, and gid of

1192 behaving confusingly. When first started, it used values for whoever
1193 started the daemon, but after a SIGHUP it used the Exim user (because it
1194 calls itself on a restart). I have changed the code so that it now always
1195 uses the Exim user.

1197PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a

1199 sender address), and a DATA command is nevertheless sent (as can happen
1200 with PIPELINING or a stupid MUA), the error message that was given to the
1201 RCPT commands is included in the rejection of the DATA command. This is
1202 intended to be helpful for MUAs that show only the final error to their
1203 users.

PH
1218 the response to the final '.' that terminates a message, but only in the
1219 case where the client has not sent further data following the '.'
1220 (unfortunately, this is allowed). However, in many cases there won't be
1221 any further data because there won't be any more messages to send. A call
1222 to select() can be used: if it shows that the input is "ready", there is
1223 either input waiting, or the socket has been closed. An attempt to read
1224 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1225 would have sent an OK response which the client would never have see.

1233Exim version 4.66
1234-----------------
1235
1236PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1237 fixed by 4.65/MH/01 (is this a record?) are fixed:
1238
1239 (i) An empty string was always treated as zero by the numeric comparison
1240 operators. This behaviour has been restored.
1241
1242 (ii) It is documented that the numeric comparison operators always treat
1243 their arguments as decimal numbers. This was broken in that numbers
1244 starting with 0 were being interpreted as octal.
1245
1246 While fixing these problems I realized that there was another issue that
1247 hadn't been noticed. Values of message_size_limit (both the global option
1248 and the transport option) were treated as octal if they started with 0.
1249 The documentation was vague. These values are now always treated as
1250 decimal, and I will make that clear in the documentation.

1264PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1265 child addresses, Exim now panics and dies. Previously, because the count
1266 is held in a short int, deliveries were likely to be lost. As such a
1267 large number of recipients for a single message is ridiculous
1268 (performance will be very, very poor), I have chosen to impose a limit
1269 rather than extend the field.

1285TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

PH
1294PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1295 callout verification, Exim cached a "reject" for the entire domain. This
1296 is correct for most verifications, but it is not correct for a recipient
1297 verification with use_sender or use_postmaster set, because in that case
1298 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1299 case of MAIL FROM:<> rejection from other early rejections (e.g.
1300 rejection of HELO). When verifying a recipient using a non-null MAIL
1301 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1302 Whatever the result of the callout, the value of the domain cache is
1303 left unchanged (for any other kind of callout, getting as far as trying
1304 RCPT means that the domain itself is ok).

1338PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1340 probably the interface on which it is arriving) and not to the outgoing
1341 callout (which could be using a different interface). This has been
1342 changed to use the value of the helo_data option from the smtp transport
1343 instead - this is what is used when a message is actually being sent. If
1344 there is no remote transport (possible with a router that sets up host
1345 addresses), $smtp_active_hostname is used.

7befa435 1348 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1349 (a) The code assumed that strncpy() returns a negative number on buffer
1350 overflow, which isn't the case. Replaced with Exim's string_format()
1351 function.
1352 (b) There were several signed/unsigned issues. I just did the minimum
1353 hacking in of casts. There is scope for a larger refactoring.
1354 (c) The code used strcasecmp() which is not a standard C function.
1355 Replaced with Exim's strcmpic() function.
1356 (d) The code set only $1; it now sets $auth1 as well.
1357 (e) A simple test gave the error "authentication client didn't specify
1358 service in request". It would seem that Dovecot has changed its
1359 interface. Fortunately there's a specification; I followed it and
1360 changed what the client sends and it appears to be working now.

1366 address A is aliased to B and C, where B exists and C does not. Without
1367 -v the output is "A verified" because verification stops after a
1368 successful redirection if more than one address is generated. However,
1369 with -v the child addresses are also verified. Exim was outputting "A
1370 failed to verify" and then showing the successful verification for C,
1371 with its parentage. It now outputs "B failed to verify", showing B's
1372 parentage before showing the successful verification of C.

322050c2
PH
1378PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1379 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1380 they consult the DNS. I had assumed they would set it the way they
1381 wanted; and indeed my experiments on Linux seem to show that in some
1382 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1383 To be on the safe side, however, I have now made the interface to
1384 host_find_byname() similar to host_find_bydns(), with an argument
1385 containing the DNS resolver options. The host_find_byname() function now
1386 sets these options at its start, just as host_find_bydns() does. The smtp
1387 transport options dns_qualify_single and dns_search_parents are passed to
1388 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1389 of host_find_byname() use the default settings of RES_DEFNAMES
1390 (qualify_single) but not RES_DNSRCH (search_parents).

1393 spool_read_header() do less string testing, by means of a preliminary
1394 switch on the second character of optional "-foo" lines. (This is
1395 overdue, caused by the large number of possibilities that now exist.
1396 Originally there were few.) While I was there, I also converted the
1397 str(n)cmp tests so they don't re-test the leading "-" and the first
1398 character, in the hope this might squeeze out yet more improvement.

1400PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1401 flag allowing group syntax was set by the header_syntax check but not
1402 turned off, possible causing trouble later; (2) The flag was not being
1403 set at all for the header_verify test, causing "group"-style headers to
1404 be rejected. I have now set it in this case, and also caused header_
1405 verify to ignore an empty address taken from a group. While doing this, I
1406 came across some other cases where the code for allowing group syntax
1407 while scanning a header line wasn't quite right (mostly, not resetting
1408 the flag correctly in the right place). These bugs could have caused
1409 trouble for malformed header lines. I hope it is now all correct.

PH
1411PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1412 with the "reply" argument non-NULL. The code, however (which originally
1413 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1414 but it didn't always do it. This confused somebody who was copying the
1415 code for some other use. I have removed all the tests.

PH
1417PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1418 feature that was used to support insecure browsers during the U.S. crypto
1419 embargo. It requires special client support, and Exim is probably the
1420 only MTA that supported it -- and would never use it because real RSA is
1421 always available. This code has been removed, because it had the bad
1422 effect of slowing Exim down by computing (never used) parameters for the
1423 RSA_EXPORT functionality.

1426 authenticator to fail if there's a tab character in the incoming data
1427 (there should never be unless someone is messing about, as it's supposed
1428 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1429 if the connection is using TLS or if the remote IP is the same as the
1430 local IP, and the "valid-client-cert option" if a client certificate has
1431 been verified.

1462
1463PH/30 Exim was sometimes attempting to deliver messages that had suffered
1464 address errors (4xx response to RCPT) over the same connection as other
1465 messages routed to the same hosts. Such deliveries are always "forced",
1466 so retry times are not inspected. This resulted in far too many retries
1467 for the affected addresses. The effect occurred only when there were more
1468 hosts than the hosts_max_try setting in the smtp transport when it had
1469 the 4xx errors. Those hosts that it had tried were not added to the list
1470 of hosts for which the message was waiting, so if all were tried, there
1471 was no problem. Two fixes have been applied:
1472
1473 (i) If there are any address or message errors in an SMTP delivery, none
1474 of the hosts (tried or untried) are now added to the list of hosts
1475 for which the message is waiting, so the message should not be a
1476 candidate for sending over the same connection that was used for a
1477 successful delivery of some other message. This seems entirely
1478 reasonable: after all the message is NOT "waiting for some host".
1479 This is so "obvious" that I'm not sure why it wasn't done
1480 previously. Hope I haven't missed anything, but it can't do any
1481 harm, as the worst effect is to miss an optimization.
1482
1483 (ii) If, despite (i), such a delivery is accidentally attempted, the
1484 routing retry time is respected, so at least it doesn't keep
1485 hammering the server.

1500PH/35 The error "getsockname() failed: connection reset by peer" was being
1501 written to the panic log as well as the main log, but it isn't really

1503 removed the panic log writing for the ECONNRESET error when getsockname()
1504 fails.
1505
48c7f9e2
PH
1506PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1507 runs only) independently of the message's sender address. This meant
1508 that, if the 4xx error was in fact related to the sender, a different
1509 message to the same recipient with a different sender could confuse
1510 things. In particualar, this can happen when sending to a greylisting
1511 server, but other circumstances could also provoke similar problems.
1512 I have changed the default so that the retry time for these errors is now
1513 based a combination of the sender and recipient addresses. This change
1514 can be overridden by setting address_retry_include_sender=false in the
1515 smtp transport.

1783PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

1785 Unfortunately, if there is a major crisis, such as a disk failure,
1786 tcp-wrappers gives "deny", whereas what one would like would be some
1787 kind of temporary error. A kludge has been added to help with this.
1788 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1789 554 error is used if errno is still zero or contains ENOENT (which occurs
1790 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1791 451 error is used.

1816 used only to exclude .Trash (or whatever) when the size of the mailbox

1827PH/01 The code for finding all the local interface addresses on a FreeBSD
1828 system running IPv6 was broken. This may well have applied to all BSD
1829 systems, as well as to others that have similar system calls. The broken
1830 code found IPv4 interfaces correctly, but gave incorrect values for the
1831 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1832 that it would not match correctly against @[] and not recognize the IPv6
1833 addresses as local.

1876 autoreply, Exim could try to deliver to a non-existent relative file
1877 name, causing unrelated and misleading errors. What now happens is that

1899 (a) Failures to set uid/gid, the current directory, or a process leader
1900 in a subprocess such as that created by queryprogram now generate
1901 suitable debugging ouput when -d is set.

1905 the subprocess without attempting to change uid/gid.

1911 additional section of a DNS packet that returns MX or SRV records.
1912 Instead, it always explicitly searches for A/AAAA records. This avoids
1913 major problems that occur when a DNS server includes only records of one
1914 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1915 fixed another bug: if SRV records were looked up and the corresponding
1916 address records were *not* found in the additional section, the port
1917 values from the SRV records were lost.

1919PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
1927PH/19 When calculating a retry time, Exim used to measure the "time since
1928 failure" by looking at the "first failed" field in the retry record. Now
1929 it does not use this if it is later than than the arrival time of the
1930 message. Instead it uses the arrival time. This makes for better
1931 behaviour in cases where some deliveries succeed, thus re-setting the
1932 "first failed" field. An example is a quota failure for a huge message
1933 when small messages continue to be delivered. Without this change, the
1934 "time since failure" will always be short, possible causing more frequent
1935 delivery attempts for the huge message than are intended.

PH
2032PH/42 The content-scanning code uses fopen() to create files in which to put
2033 message data. Previously it was not paying any attention to the mode of
2034 the files. Exim runs with umask(0) because the rest of the code creates
2035 files with open(), and sets the required mode explicitly. Thus, these
2036 files were ending up world-writeable. This was not a big issue, because,
2037 being within the spool directory, they were not world-accessible. I have
2038 created a function called modefopen, which takes an additional mode
2039 argument. It sets umask(777), creates the file, chmods it to the required
2040 mode, then resets the umask. All the relevant calls to fopen() in the
2041 content scanning code have been changed to use this function.

2078
2079 (i) Exim was not creating retry information for temporary errors given
2080 for individual recipients after the DATA command when the smtp transport
2081 was used in LMTP mode. This meant that they could be retried too
2082 frequently, and not timed out correctly.
2083
2084 (ii) Exim was setting the flag that allows error details to be returned
2085 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2086 recipients that were returned after the DATA command.
2087
2088PH/53 This is related to PH/52, but is more general: for any failing address,
2089 when detailed error information was permitted to be returned to the

2162PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2163 function verify_get_ident() calls ip_connect() to connect a socket, but
2164 if the "connect()" function timed out, ip_connect() used to close the
2165 socket. However, verify_get_ident() also closes the socket later, and in
2166 between Exim writes to the log, which may get opened at this point. When
2167 the socket was closed in ip_connect(), the log could get the same file
2168 descriptor number as the socket. This naturally causes chaos. The fix is
2169 not to close the socket in ip_connect(); the socket should be closed by
2170 the function that creates it. There was only one place in the code where
2171 this was missing, in the iplookup router, which I don't think anybody now
2172 uses, but I've fixed it anyway.

2199 (3) Reset the variables that are obtained from the first argument of
2200 ${prvscheck and used in the second argument before leaving the code,
2201 because their memory is reclaimed, so using them afterwards may do
2202 silly things.

2229 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2230 not being looked up in the rDNS to get a host name, Exim was showing the
2231 IP address twice in Received: lines, even though the IP addresses were
2232 identical. For example:
2233
2234 Received: from [1.2.3.4] (helo=[1.2.3.4])
2235
2236 However, if the real host name was known, it was omitting the HELO data

2330 addresses acquired from the DNS when checking that the found name did
2331 have the original IP as one of its addresses. Since any found IPv6
2332 addresses are likely to be in abbreviated form, the comparison could
2333 fail. Luckily, there already exists a function for doing the comparison
2334 by converting both addresses to binary, so now that is used instead of

TK
2372Exim version 4.53

2376 NewStuff for rationale and an example.

5b68f6e4
PH
2382PH/03 When creating an mbox file for a virus/spam scan, use fseek() instead of
2383 fread() to skip over the body file's header line, because in Cygwin the
2384 header line is locked and is inaccessible.
2385
1ab52c69
PH
2386PH/04 Added $message_exim_id, ultimately to replace $message_id (they will both
2387 co-exist for some time) to make it clear that it is the Exim ID that is
2388 referenced, not the Message-ID: header line.
2389
b07e6aa3
PH
2390PH/05 Replaced all Tom's calls to snprintf() with calls to the internal
2391 string_format() function, because snprintf() does not exist on all
2392 operating systems.
2393
254e032f
PH
2394PH/06 The use of forbid_filter_existstest now also locks out the use of the
2395 ${stat: expansion item.

2397PH/07 Changed "SMTP protocol violation: synchronization error" into "SMTP
2398 protocol synchronization error", to keep the pedants happy.

PH
2400PH/08 Arrange for USE_INET_NTOA_FIX to be set in config.h for AIX systems as

2410 transport and to the smtp transport in LMTP mode.

PH
2412TK/02 Remove one case of BASE64 error detection FTTB (undocumented anyway).
2413
af46795e
PH
2414PH/12 There was a missing call to search_tidyup() before the fork() in rda.c to
2415 run a filter in a subprocess. This could lead to confusion in subsequent
2416 lookups in the parent process. There should also be a search_tidyup() at
2417 the end of the subprocess.
2418
d7b47fd0
PH
2419PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
2420 only if the host matched helo_try_verify_hosts, which caused the
2421 verification to occur when the EHLO/HELO command was issued. The ACL just
2422 tested the remembered result. Now, if a previous verification attempt has
2423 not happened, "verify = helo" does it there and then.

PH
2442PH/20 If a delivery was routed to a non-standard port by means of an SRV
2443 record, the port was not correctly logged when the outgoing_port log
2444 selector was set (it logged the transort's default port).

2447 fallback_hosts, and "hosts" in the smtp transport.

PH
2452PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
2453 authentication with radiusclient 0.4.9:
2454
2455 - Error returned from rc_read_config was caught wrongly
2456 - Username/password not passed on to radius server due to wrong length.
2457
2458 The presumption is that some radiusclient API changes for 4.51/PH/17
2459 were not taken care of correctly. The code is still untested by me (my
2460 Linux distribution still has 0.3.2 of radiusclient), but it was
2461 contributed by a Radius user.

PH
2476PH/26 Exim was recognizing IPv6 addresses of the form [IPv6:....] in EHLO
2477 commands, but it was not correctly comparing the address with the actual
2478 client host address. Thus, it would show the EHLO address in Received:
2479 header lines when this was not necessary.

ba18e66a
PH
2483PH/28 Exim tries to create and chdir to its spool directory when it starts;
2484 it should be ignoring failures (because with -C, for example, it has lost

2503
2504PH/34 There are settings for CHOWN_COMMAND and MV_COMMAND that can be used in
2505 Local/Makefile (with some defaults set). These are used in built scripts
2506 such as exicyclog, but they have never been used in the exim_install
2507 script (though there are many overriding facilities there). I have
2508 arranged that the exim_install script now takes note of these two
2509 settings.

PH
2513PH/36 When a locally submitted message by a trusted user did not contain a
2514 From: header, and the sender address was obtained from -f or from an SMTP
2515 MAIL command, and the trusted user did not use -F to supply a sender
2516 name, $originator_name was incorrectly used when constructing a From:
2517 header. Furthermore, $originator_name was used for submission mode
2518 messages from external hosts without From: headers in a similar way,
2519 which is clearly wrong.

ccfdb010
PH
2523PH/38 When log_selector = +received_sender was set, and the addition of the
2524 sender made the log line's construction buffer exactly full, or one byte
2525 less than full, an overflow happened when the terminating "\n" was
2526 subsequently added.
2527
1130bfb0
PH
2528PH/39 Added a new log selector, "unknown_in_list", which provokes a log entry
2529 when the result of a list match is failure because a DNS lookup failed.

PH
2536PH/42 (But a TF fix): In a domain list, Exim incorrectly matched @[] if the IP
2537 address in a domain literal was a prefix of an interface address.

fd6de02e
PH
2539PH/43 (Again a TF fix): In the dnslookup router, do not apply widen_domains
2540 when verifying a sender address, unless rewrite_headers is false.

PH
2552PH/47 Added an interface to a fake DNS resolver for use by the new test suite,
2553 avoiding the need to install special zones in a real server. This is
2554 backwards compatible; if it can't find the fake resolver, it drops back.

TF
2585TF/08 Change PH/13 introduced the possibility that verify=helo may defer,
2586 if the DNS of the sending site is misconfigured. This is quite a

PH
2599PH/01 When a transport filter timed out in a pipe delivery, and the pipe

PH
2609PH/03 The warning log line about a condition test deferring for a "warn" verb
2610 was being output only once per connection, rather than after each

87ba3f5f
PH
2614TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that
2615 it should not have, which might have caused a crash in the right
2616 circumstances, but probably never did.
2617
2618PH/04 Installed a modified version of Tony Finch's patch to make submission
2619 mode fix the return path as well as the Sender: header line, and to

415c8f3b
PH
2632PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2633 with the definition in sysexits.h (which is #included earlier).
2634 Fortunately, Exim does not actually use EX_OK. The code used to try to
2635 preserve the sysexits.h value, by assumimg that macro definitions were
2636 scanned for macro replacements. I have been disabused of this notion,
2637 so now the code just undefines EX_OK before #including unistd.h.
11d337a4 2638
958541e9
PH
2639PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
2640 in the smtp transport. When a block could not be written in a single
2641 write() function, the timeout was being re-applied to each part-write.
2642 This seems wrong - if the receiver was accepting one byte at a time it
2643 would take for ever. The timeout is now adjusted when this happens. It
2644 doesn't have to be particularly precise.

2673TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers.

PH
2710PH/15 The code I had for printing potentially long long variables in PH/11

c6c2dc1d
PH
2713 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T

PH
2717PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
2718 the configuration file to be ":syslog", then the script "guesses" where
2719 the logs files are, rather than using the compiled in default. In our
2720 case the guess is not the same as the compiled default, so the script
2721 suddenly stopped working when I started to use syslog. The patch checks
2722 to see if log_file_path is "". If so, it attempts to read it from exim
2723 with no configuration file to get the compiled in version, before it
2724 falls back to the previous guessing code."

2783 read the rcpt_include_affixes from the non-existent transport. Now it
2784 just assumes that the setting of that option is false. This bug was

2852
2853PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2854 that changes the way the GnuTLS parameters are stored in the cache file.
2855 The new format can be generated externally. For backward compatibility,
2856 if the data in the cache doesn't make sense, Exim assumes it has read an
2857 old-format file, and it generates new data and writes a new file. This
2858 means that you can't go back to an older release without removing the
2859 file.
2860
2861PH/03 A redirect router that has both "unseen" and "one_time" set does not
2862 work if there are any delivery delays because "one_time" forces the
2863 parent to be marked "delivered", so its unseen clone is never tried
2864 again. For this reason, Exim now forbids the simultaneous setting of
2865 these two options.
2866
2867PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2868 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2869 entry if you want to know the details. The fix, however, neglected to
2870 consider the case when local delivery batching is involved. The test for
2871 "previously delivered" was not happening when checking to see if an
2872 address could be batched with a previous (undelivered) one; under
2873 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2874 address.

2879PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2880 header_syntax) but Exim was just ignoring anything given after a slash.
2881 In particular, this caused confusion with an attempt to use "verify =
2882 reverse_host_lookup/defer_ok". An error is now given when options are
2883 supplied for verify items that do not have them. (Maybe reverse_host_
2884 lookup should have a defer_ok option, but that's a different point.)

2939 the file with the wrong ownership). There was no test for failure of this
2940 fork() call, which would lead to the process getting stuck as it waited
2941 for a non-existent subprocess. Forks do occasionally fail when resources

2949 string after "input=" when read() returned zero. If read() returned -1

2962PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2963 hadn't been configured. The fix is from Juergen Kreileder, who
2964 understands it better than I do:
2965
2966 "Here's what I see happening with three configured cyrus_sasl
2967 authenticators configured (plain, login, cram-md5):
2968
2969 On startup auth_cyrus_sasl_init() gets called for each of these.
2970 This means three calls to sasl_listmech() without a specified mech_list.
2971 => SASL tests which mechs of all available mechs actually work
2972 => three warnings about OTP not working
2973 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2974
2975 With the patch, sasl_listmech() also gets called three times. But now
2976 SASL's mech_list option is set to the server_mech specified in the the
2977 authenticator. Or in other words, the answer from sasl_listmech()
2978 gets limited to just the mech you're testing for (which is different
2979 for each call.)
2980 => the return list contains just 'plain' or 'login', 'cram-md5' or
2981 nothing depending on the value of ob->server_mech.
2982
2983 I've just tested the patch: Authentication still works fine,

3049PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3050 the grounds that routing the same address twice would always produce the
3051 same answer. This might have been true once, but it is certainly no
3052 longer true now. Routing a child address may depend on the previous
3053 routing that produced that child. Some complicated redirection strategies
3054 went wrong when messages had multiple recipients, and made Exim's
3055 behaviour dependent on the order in which the addresses were given.
3056
3057 I have moved the duplicate checking until after the routing is complete.
3058 Exim scans the addresses that are assigned to local and remote
3059 transports, and removes any duplicates. This means that more work will be
3060 done, as duplicates will always all be routed, but duplicates are
3061 presumably rare, so I don't expect this is of any significance.
3062
3063 For deliveries to pipes, files, and autoreplies, the duplicate checking
3064 still happens during the routing process, since they are not going to be
3065 routed further.

3110 consistency with the overall process timeout, these timeouts are now

3112 there is now a new Boolean option for the pipe transport called

3124A note about Exim versions 4.44 and 4.50
3125----------------------------------------
3126
3127Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3128changes of various kinds. As a consequence, a big documentation update was
3129needed. This delayed the release for rather longer than seemed good, especially
3130in the light of a couple of (minor) security issues. Therefore, the changes
3131that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3132release. So 4.44 and 4.50 are in effect two different branches that both start
3133from 4.43.
3134
3135I have left the 4.50 change log unchanged; it contains all the changes since
31364.43. The change log for 4.44 is below; many of its items are identical to
3137those for 4.50. This seems to be the most sensible way to preserve the
3138historical information.

3159 now done for all such subprocesses. The other cases are: ${run, transport
3160 filters, and the commands run by the lmtp and pipe transports.

PH
3162 6. Added CONFIGURE_GROUP build-time option.
3163
3164 7. Some older OS have a limit of 256 on the maximum number of file
3165 descriptors. Exim was using setrlimit() to set 1000 as a large value
3166 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3167 systems. I've change it so that if it can't get 1000, it tries for 256.

3169 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3170 was an oversight, and furthermore, ever since the addition of extra
3171 controls (e.g. 4.43/32), the checks on when to allow different forms of
3172 "control" were broken. There should now be diagnostics for all cases when a
3173 control that does not make sense is encountered.
3174

PH
3175 9. Added the /retain_sender option to "control=submission".

PH
317710. $recipients is now available in the predata ACL (oversight).
3178
eb2c0248
PH
317911. Tidy the search cache before the fork to do a delivery from a message
3180 received from the command line. Otherwise the child will trigger a lookup
3181 failure and thereby defer the delivery if it tries to use (for example) a
3182 cached ldap connection that the parent has called unbind on.
3183
2a3eea10
PH
318412. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3185 of $address_data from the recipient verification was clobbered by the
3186 sender verification.
3187
318813. The value of address_data from a sender verification is now available in
3189 $sender_address_data in subsequent conditions in the ACL statement.
3190
23c7ff99
PH
319114. Added forbid_sieve_filter and forbid_exim_filter to the redirect router.
3192
4deaf07d
PH
319315. Added a new option "connect=<time>" to callout options, to set a different
3194 connection timeout.
3195
926e1192
PH
319616. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3197 was its contents. (It was OK if the option was not defined at all.)
3198

PH
319917. A "Completed" log line is now written for messages that are removed from
3200 the spool by the -Mrm option.
3201
2c7db3f5
PH
320218. New variables $sender_verify_failure and $recipient_verify_failure contain
3203 information about exactly what failed.
3204
3d235903
PH
320519. Added -dd to debug only the daemon process.
3206
7c7ad977
PH
320720. Incorporated Michael Haardt's patch to ldap.c for improving the way it
3208 handles timeouts, both on the server side and network timeouts. Renamed the
3209 CONNECT parameter as NETTIMEOUT (but kept the old name for compatibility).
3210

PH
321121. The rare case of EHLO->STARTTLS->HELO was setting the protocol to "smtp".
3212 It is now set to "smtps".

d4eb88df
PH
321422. $host_address is now set to the target address during the checking of
3215 ignore_target_hosts.
3216
321723. When checking ignore_target_hosts for an ipliteral router, no host name was
3218 being passed; this would have caused $sender_host_name to have been used if
3219 matching the list had actually called for a host name (not very likely,
3220 since this list is usually IP addresses). A host name is now passed as
3221 "[x.x.x.x]".
3222
7d468ab8
PH
322324. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3224 code that specifies a non-restarting handler (typically sigaction() in
3225 modern systems) in an attempt to fix a rare and obscure crash bug.
3226
322725. Narrowed the window for a race in the daemon that could cause it to ignore
3228 SIGCHLD signals. This is not a major problem, because they are used only to
3229 wake it up if nothing else does.
3230
62c0818f
PH
323126. A malformed maildirsize file could cause Exim to calculate negative values
3232 for the mailbox size or file count. Odd effects could occur as a result.
3233 The maildirsize information is now recalculated if the size or filecount
3234 end up negative.
3235
26034054
PH
323627. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3237 support for a long time. Removed HAVE_SYS_VFS_H.

af66f652
PH
323928. Installed the latest version of exipick from John Jetmore.
3240
90af77f4
PH
324129. In an address list, if the pattern was not a regular expression, an empty
3242 subject address (from a bounce message) matched only if the pattern was an
3243 empty string. Non-empty patterns were not even tested. This was the wrong
3244 because it is perfectly reasonable to use an empty address as part of a
3245 database query. An empty address is now tested by patterns that are
3246 lookups. However, all the other forms of pattern expect the subject to
3247 contain a local part and a domain, and therefore, for them, an empty
3248 address still always fails if the pattern is not itself empty.
3249
d8ef3577
PH
325030. Exim went into a mad DNS loop when attempting to do a callout where the
3251 host was specified on an smtp transport, and looking it up yielded more
3252 than one IP address.
3253
5cb8cbc6
PH
325431. Re-factored the code for checking spool and log partition space into a
3255 function that finds that data and another that does the check. The former
3256 is then used to implement four new variables: $spool_space, $log_space,
3257 $spool_inodes, and $log_inodes.
3258
14702f5b
PH
325932. The RFC2047 encoding function was originally intended for short strings
3260 such as real names; it was not keeping to the 75-character limit for
3261 encoded words that the RFC imposes. It now respects the limit, and
3262 generates multiple encoded words if necessary. To be on the safe side, I
3263 have increased the buffer size for the ${rfc2047: expansion operator from
3264 1024 to 2048 bytes.
3265
063b1e99
PH
326633. It is now permitted to omit both strings after an "if" condition; if the
3267 condition is true, the result is "true". As before, when the second string
3268 is omitted, a false condition yields an empty string. This makes it less
3269 cumbersome to write custom ACL and router conditions.
3270
652e1b65
PH
327134. Failure to deliver a bounce message always caused it to be frozen, even if
3272 there was an errors_to setting on the router. The errors_to setting is now
3273 respected.
3274
6f0c9a4f
PH
327535. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3276 canonical form (fully expanded) before being placed in
3277 $sender_host_address.
3278
33397d19
PH
327936. The table in the code that translates DNS record types into text (T_A to
3280 "A" for instance) was missing entries for NS and CNAME. It is just possible
3281 that this could have caused confusion if both these types were looked up
3282 for the same domain, because the text type is used as part of Exim's
3283 per-process caching. But the chance of anyone hitting this buglet seems
3284 very small.
3285
7bb56e1f
PH
328637. The dnsdb lookup has been extended in a number of ways.
3287
3288 (1) There is a new type, "zns", which walks up the domain tree until it
3289 finds some nameserver records. It should be used with care.
3290
ea3bc19b
PH
3291 (2) There is a new type, "mxh", which is like "mx" except that it returns
3292 just the host names, not the priorities.
3293
3294 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
3295 looked up. The behaviour when one of the lookups defers can be
3296 controlled by a keyword.
7bb56e1f 3297
ea3bc19b 3298 (4) It is now possible to specify the separator character for use when
7bb56e1f 3299 multiple records are returned.
33397d19 3300
0bcb2a0e
PH
330138. The dnslists ACL condition has been extended: it is now possible to supply
3302 a list of IP addresses and/or domains to be looked up in a particular DNS
3303 domain.
3304
2ac0e484
PH
330539. Added log_selector=+queue_time_overall.
3306
4e1fde53
PH
330740. When running the queue in the test harness, wait just a tad after forking a
3308 delivery process, to get repeatability of debugging output.
3309
de365ded
PH
331041. Include certificate and key file names in error message when GnuTLS fails
3311 to set them up, because the GnuTLS error message doesn't include the name
3312 of the failing file when there is a problem reading it.
3313
f05da2e8
PH
331442. Allow both -bf and -bF in the same test run.
3315
d6453af2
PH
331643. Did the same fix as 41 above for OpenSSL, which had the same infelicity.
3317
f7b63901
PH
331844. The "Exiscan patch" is now merged into the mainline Exim source.
3319
332045. Sometimes the final signoff response after QUIT could fail to get
3321 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3322 < 0 before doing a fflush(). This bug looks as though it goes back to the
3323 introduction of TLS in release 3.20, but "sometimes" must have been rare
3324 because the tests only now provoked it.
3325
a444213a
PH
332646. Reset the locale to "C" after calling embedded Perl, in case it was changed
3327 (this can affect the format of dates).
3328
0ec020ea
PH
332947. exim_tidydb, when checking for the continued existence of a message for
3330 which it has found a message-specific retry record, was not finding
3331 messages that were in split spool directories. Consequently, it was
3332 deleting retry records that should have stayed in existence.
3333
b1206957
PH
333448. Steve fixed some bugs in eximstats.
3335
333649. The SPA authentication driver was not abandoning authentication and moving
3337 on to the next authenticator when an expansion was forced to fail,
3338 contradicting the general specification for all authenticators. Instead it
3339 was generating a temporary error. It now behaves as specified.
3340
26dd5a95
PH
334150. The default ordering of permitted cipher suites for GnuTLS was pessimal
3342 (the order specifies the preference for clients). The order is now AES256,
3343 AES128, 3DES, ARCFOUR128.
3344
343b2385
PH
334551. Small patch to Sieve code - explicitly set From: when generating an
3346 autoreply.
3347
1c5466b9
PH
334852. Exim crashed if a remote delivery caused a very long error message to be
3349 recorded - for instance if somebody sent an entire SpamAssassin report back
3350 as a large number of 550 error lines. This bug was coincidentally fixed by
3351 increasing the size of one of Exim's internal buffers (big_buffer) that
3352 happened as part of the Exiscan merge. However, to be on the safe side, I
3353 have made the code more robust (and fixed the comments that describe what
3354 is going on).
3355
55ee9ee3
PH
335653. Now that there can be additional text after "Completed" in log lines (if
3357 the queue_time_overall log selector is set), a one-byte patch to exigrep
3358 was needed to allow it to recognize "Completed" as not the last thing in
3359 the line.
3360
d38f8232
PH
336154. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3362 patch that reportedly fixes this has been added. I am not expert enough to
3363 create a test for it. This is what the patch creator wrote:
3364
3365 "I found a little strange behaviour of ldap code when working with
3366 Windows 2003 AD Domain, where users was placed in more than one
3367 Organization Units. When I tried to give exim partial DN, the exit code
3368 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3369 But simultaneously result of request was absolutely normal ldap result,
3370 so I produce this patch..."
3371
3295e65b
PH
3372 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3373 REFERENCE, so I have modified the code to exclude the patch when that macro
3374 is not defined.
3375
7102e136
PH
337655. Some experimental protocols are using DNS PTR records for new purposes. The
3377 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3378 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3379 leaves it alone. Component reversal etc. now happens only for IP addresses.
