8Exim version 4.90
9-----------------
10
11JH/01 Rework error string handling in TLS interface so that the caller in
12 more cases is responsible for logging. This permits library-sourced
13 string to be attached to addresses during delivery, and collapses
14 pairs of long lines into single ones.
15
856d1e16
PP
16PP/01 Allow PKG_CONFIG_PATH to be set in Local/Makefile and use it correctly
17 during configuration. Wildcards are allowed and expanded.

JH
19JH/02 Rework error string handling in DKIM to pass more info back to callers.
20 This permits better logging.
21
875512a3
JH
22JH/03 Rework the transport continued-connection mechanism: when TLS is active,
23 do not close it down and have the child transport start it up again on
24 the passed-on TCP connection. Instead, proxy the child (and any
25 subsequent ones) for TLS via a unix-domain socket channel. Logging is
26 affected: the continued delivery log lines do not have any DNSSEC, TLS
5013d912 27 Certificate or OCSP information. TLS cipher information is still logged.

29JH/04 Shorten the log line for daemon startup by collapsing adjacent sets of
30 identical IP addresses on different listening ports. Will also affect
31 "exiwhat" output.

33PP/02 Bug 2070: uClibc defines __GLIBC__ without providing glibc headers;
34 add noisy ifdef guards to special-case this sillyness.
35 Patch from Bernd Kuhls.

JH
37JH/05 Tighten up the checking in isip4 (et al): dotted-quad components larger
38 than 255 are no longer allowed.
39
7006ee24
JH
40JH/06 Default openssl_options to include +no_ticket, to reduce load on peers.
41 Disable the session-cache too, which might reduce our load. Since we
42 currrectly use a new context for every connection, both as server and
43 client, there is no benefit for these.
44 GnuTLS appears to not support tickets server-side by default (we don't
45 call gnutls_session_ticket_enable_server()) but client side is enabled
46 by default on recent versions (3.1.3 +) unless the PFS priority string
47 is used (3.2.4 +).

50 <https://reproducible-builds.org/specs/source-date-epoch/>.

JH
52JH/07 Fix smtp transport use of limited max_rcpt under mua_wrapper. Previously
53 the check for any unsuccessful recipients did not notice the limit, and
54 erroneously found still-pending ones.
55
4e910c01
JH
56JH/08 Pipeline CHUNKING command and data together, on kernels that support
57 MSG_MORE. Only in-clear (not on TLS connections).
58
42055a33
JH
59JH/09 Avoid using a temporary file during transport using dkim. Unless a
60 transport-filter is involved we can buffer the headers in memory for
61 creating the signature, and read the spool data file once for the
62 signature and again for transmission.

79JH/04 Bug 2004: fix CHUNKING in non-PIPELINEING mode. Chunk data following
80 close after a BDAT command line could be taken as a following command,
81 giving a synch failure. Fix by only checking for synch immediately
82 before acknowledging the chunk.

JH
88JH/05 Have the EHLO response advertise VRFY, if there is a vrfy ACL defined.
89 Previously we did not; the RFC seems ambiguous and VRFY is not listed
90 by IANA as a service extension. However, John Klensin suggests that we
91 should.

95 CRLF, so prepend a CR to any bare LF.

902fbd69
JH
98 As a side-benfit, callouts can now use PIPELINING hence fewer round-trips.
99

JH
100JH/08 Bug 2016: Fix DKIM verification vs. CHUNKING. Any BDAT commands after
101 the first were themselves being wrongly included in the feed into dkim
102 processing; with most chunk sizes in use this resulted in an incorrect
103 body hash calculated value.
104

JH
105JH/09 Bug 2014: permit inclusion of a DKIM-Signature header in a received
106 DKIM signature block, for verification. Although advised against by
107 standards it is specifically not ruled illegal.

111JH/11 Bug 2029: Fix crash in DKIM verification when a message signature block is
112 missing a body hash (the bh= tag).
113
114JH/12 Bug 2018: Re-order Proxy Protocol startup versus TLS-on-connect startup.
115 It seems that HAProxy sends the Proxy Protocol information in clear and
116 only then does a TLS startup, so do the same.
117
118JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
119 TCP connections (such as for Spamd) unless the daemon successfully set
120 Fast Open mode on its listening sockets. This fixes breakage seen on
121 too-old kernels or those not configured for Fast Open, at the cost of
122 requiring both directions being enabled for TFO, and TFO never being used
123 by non-daemon-related Exim processes.
124
125JH/14 Bug 2000: Reject messages recieved with CHUNKING but with malformed line
126 endings, at least on the first header line. Try to canonify any that get
127 past that check, despite the cost.
128

129JH/15 Angle-bracket nesting (an error inserted by broken sendmails) levels are
130 now limited to an arbitrary five deep, while parsing addresses with the
131 strip_excess_angle_brackets option enabled.

133PP/03 Bug 2018: For Proxy Protocol and TLS-on-connect, do not over-read and
134 instead leave the unprompted TLS handshake in socket buffer for the
135 TLS library to consume.

140
90341c71
JH
141JH/16 Drop variables when they go out of scope. Memory management drops a whole
142 region in one operation, for speed, and this leaves assigned pointers
143 dangling. Add checks run only under the testsuite which checks all
144 variables at a store-reset and panics on a dangling pointer; add code
145 explicitly nulling out all the variables discovered. Fixes one known
146 bug: a transport crash, where a dangling pointer for $sending_ip_address
147 originally assigned in a verify callout, is re-used.

149PP/06 Drop '.' from @INC in various Perl scripts.

151PP/07 Switch FreeBSD iconv to always use the base-system libc functions.

153PP/08 Reduce a number of compilation warnings under clang; building with
154 CC=clang CFLAGS+=-Wno-dangling-else -Wno-logical-op-parentheses
155 should be warning-free.

178 supports it and a size is available (ie. the sending peer gave us one).

JH
180JH/02 The obsolete acl condition "demime" is removed (finally, after ten
181 years of being deprecated). The replacements are the ACLs
182 acl_smtp_mime and acl_not_smtp_mime.
183
4b0fe319
JH
184JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
185 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
186 or even an in-clear connection were permitted. Now, if the host lookup
187 was dnssec and dane was requested then the host is only used if the
188 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
189 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
190 if one fails this test.
191 This means that a poorly-configured remote DNS will make it incommunicado;
192 but it protects against a DNS-interception attack on it.

JH
214JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
215 a cutthrough deliver is pending, as we always want to make a connection.
216 This also avoids re-routing the message when later placing the cutthrough
217 connection after a verify cache hit.
218 Do not update it with the verify result either.
219
220JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
221 when routing results in more than one destination address.
222
ae8386f0
JH
223JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
224 signing (which inhibits the cutthrough capability). Previously only
225 the presence of an option was tested; now an expansion evaluating as
226 empty is permissible (obviously it should depend only on data available
227 when the cutthrough connection is made).

1006TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
1007
1008 When a queue runner is handling a message, Exim first routes the
1009 recipient addresses, during which it prunes them based on the retry
1010 hints database. After that it attempts to deliver the message to
1011 any remaining recipients. It then updates the hints database using
1012 the retry rules.
1013
1014 So if a recipient address works intermittently, it can get repeatedly
1015 deferred at routing time. The retry hints record remains fresh so the
1016 address never reaches the final cutoff time.
1017
1018 This is a fairly common occurrence when a user is bumping up against
1019 their storage quota. Exim had some logic in its local delivery code
1020 to deal with this. However it did not apply to per-recipient defers
1021 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1022
1ddeb334
TF
1023 This change adds a proper retry rule check during routing so that the
1024 final cutoff time is checked against the message's age. We only do
1025 this check if there is an address retry record and there is not a
1026 domain retry record; this implies that previous attempts to handle
1027 the address had the retry_use_local_parts option turned on. We use
1028 this as an approximation for the destination being like a local
1029 delivery, as in LMTP.
67bd1ab3
TF
1030
1031 I suspect this new check makes the old local delivery cutoff check
1032 redundant, but I have not verified this so I left the code in place.

1040 When I ran the test suite under the user fanf2, Exim expanded
1041 the header to contain my full name, whereas it should have added
1042 a Resent-Sender: header. It erroneously treats any prefix of the
1043 username as equal to the username.

1354TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1355 lock up or crash if it happened to be inside a call to libc when it
1356 got a SIGUSR1 from exiwhat.
1357
1358 The SIGUSR1 handler appends the current process status to the process
1359 log which is later printed by exiwhat. It used to use the general
1360 purpose logging code to do this, but several functions it calls are
1361 not safe for signals.
1362
1363 The new output code in the SIGUSR1 handler is specific to the process
1364 log, and simple enough that it's easy to inspect for signal safety.
1365 Removing some special cases also simplifies the general logging code.
1366 Removing the spurious timestamps from the process log simplifies
1367 exiwhat.
1368
c99ce5c9
TF
1369TF/04 Improved ratelimit ACL condition.
1370
1371 The /noupdate option has been deprecated in favour of /readonly which
1372 has clearer semantics. The /leaky, /strict, and /readonly update modes
1373 are mutually exclusive. The update mode is no longer included in the
1374 database key; it just determines when the database is updated. (This
4c04137d 1375 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1376
1377 Exim now checks that the per_* options are used with an update mode that
1378 makes sense for the current ACL. For example, when Exim is processing a
1379 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1380 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1381 must specify per_mail/readonly. If you omit the update mode it defaults to
1382 /leaky where that makes sense (as before) or /readonly where required.
1383
1384 The /noupdate option is now undocumented but still supported for
1385 backwards compatibility. It is equivalent to /readonly except that in
1386 ACLs where /readonly is required you may specify /leaky/noupdate or
1387 /strict/noupdate which are treated the same as /readonly.
1388
1389 A useful new feature is the /count= option. This is a generalization
1390 of the per_byte option, so that you can measure the throughput of other
1391 aggregate values. For example, the per_byte option is now equivalent
1392 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1393
1394 The per_rcpt option has been generalized using the /count= mechanism
1395 (though it's more complicated than the per_byte equivalence). When it is
1396 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1397 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1398 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1399 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1400 Note that using per_rcpt with a non-readonly update mode in more than
1401 one ACL will cause the recipients to be double-counted. (The per_mail
1402 and per_byte options don't have this problem.)
1403
1404 The handling of very low rates has changed slightly. If the computed rate
1405 is less than the event's count (usually one) then this event is the first
1406 after a long gap. In this case the rate is set to the same as this event's
1407 count, so that the first message of a spam run is counted properly.
1408
1409 The major new feature is a mechanism for counting the rate of unique
1410 events. The new per_addr option counts the number of different
1411 recipients that someone has sent messages to in the last time period. It
1412 behaves like per_rcpt if all the recipient addresses are different, but
1413 duplicate recipient addresses do not increase the measured rate. Like
1414 the /count= option this is a general mechanism, so the per_addr option
1415 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1416 example, measure the rate that a client uses different sender addresses
1417 with the options per_mail/unique=$sender_address. There are further
1418 details in the main documentation.

1969 were called 'true' and it seems that C99 defines that as a reserved

1989
1990PH/01 Another patch from the Sieve maintainer.
1991
6a3bceb1
PH
1992PH/02 When an IPv6 address is converted to a string for single-key lookup
1993 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1994 dots are used instead of colons so that keys in lsearch files need not
1995 contain colons. This was done some time before quoting was made available
1996 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1997 (notated using the quote facility) so as to distinguish them from IPv4
1998 keys. This meant that lookups for IP addresses in host lists did not work
1999 for iplsearch lookups.
2000
2001 This has been fixed by arranging for IPv6 addresses to be expressed with
2002 colons if the lookup type is iplsearch. This is not incompatible, because
2003 previously such lookups could never work.
2004
4c04137d 2005 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2006 ordinary lsearch keys. However, making the change in all cases is
2007 incompatible and would probably break a number of configurations.

MH
2012MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2013 conversion specification without a maximum field width, thereby enabling
2014 a rogue spamd server to cause a buffer overflow. While nobody in their
2015 right mind would setup Exim to query an untrusted spamd server, an
2016 attacker that gains access to a server running spamd could potentially
2017 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
2022MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2023 a directory entry by the name of the lookup key. Previously, if a
2024 symlink pointed to a non-existing file or a file in a directory that
2025 Exim lacked permissions to read, a lookup for a key matching that
2026 symlink would fail. Now it is enough that a matching directory entry
2027 exists, symlink or not. (Bugzilla 503.)

2104 if a client was not listed at all, or was listed with a value other than

PH
2210PH/29 SMTP synchronization checks are implemented when a command is read -
2211 there is a check that no more input is waiting when there shouldn't be
2212 any. However, for some commands, a delay in an ACL can mean that it is
2213 some time before the response is written. In this time, more input might
2214 arrive, invalidly. So now there are extra checks after an ACL has run for
2215 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2216 pipelining has not been advertised.

PH
2228PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in

2230 SSL_CTX_set_info_callback() might give an error value. In fact, there is
2231 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
2232 was a macro that became an assignment, so it seemed to work. This has
2233 changed to a proper function call with a void return, hence the compile
2234 error. Exim's code has been fixed.

2265 started the daemon, but after a SIGHUP it used the Exim user (because it

2272 with PIPELINING or a stupid MUA), the error message that was given to the

PH
2290 the response to the final '.' that terminates a message, but only in the
2291 case where the client has not sent further data following the '.'
2292 (unfortunately, this is allowed). However, in many cases there won't be
2293 any further data because there won't be any more messages to send. A call
2294 to select() can be used: if it shows that the input is "ready", there is
2295 either input waiting, or the socket has been closed. An attempt to read
2296 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2297 would have sent an OK response which the client would never have see.

2309 fixed by 4.65/MH/01 (is this a record?) are fixed:
2310
2311 (i) An empty string was always treated as zero by the numeric comparison
2312 operators. This behaviour has been restored.
2313
2314 (ii) It is documented that the numeric comparison operators always treat
2315 their arguments as decimal numbers. This was broken in that numbers
2316 starting with 0 were being interpreted as octal.
2317
2318 While fixing these problems I realized that there was another issue that
2319 hadn't been noticed. Values of message_size_limit (both the global option
2320 and the transport option) were treated as octal if they started with 0.
2321 The documentation was vague. These values are now always treated as
2322 decimal, and I will make that clear in the documentation.

PH
2336PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
2337 child addresses, Exim now panics and dies. Previously, because the count
2338 is held in a short int, deliveries were likely to be lost. As such a
2339 large number of recipients for a single message is ridiculous
2340 (performance will be very, very poor), I have chosen to impose a limit
2341 rather than extend the field.

2347TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2348 leftover -K file (the existence of which was triggered by #402).
2349 While we were at it, introduced process PID as part of the -K
2350 filename. This should rule out race conditions when creating
2351 these files.
2352
2353TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
2354 processing considerably. Previous code took too long for large mails,
2355 triggering a timeout which in turn triggers #401.
2356
2357TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
2358 in the DK code in transports.c. sendfile() is not really portable,
2359 hence the _LINUX specificness.

2361TF/01 In the add_headers option to the mail command in an Exim filter,
2362 there was a bug that Exim would claim a syntax error in any
2363 header after the first one which had an odd number of characters
2364 in the field name.
2365
2b1c6e3a
PH
2366PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2367 callout verification, Exim cached a "reject" for the entire domain. This
2368 is correct for most verifications, but it is not correct for a recipient
2369 verification with use_sender or use_postmaster set, because in that case
2370 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2371 case of MAIL FROM:<> rejection from other early rejections (e.g.
2372 rejection of HELO). When verifying a recipient using a non-null MAIL
2373 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2374 Whatever the result of the callout, the value of the domain cache is
2375 left unchanged (for any other kind of callout, getting as far as trying
2376 RCPT means that the domain itself is ok).

2410PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2411 hostname. This is wrong, because it relates to the incoming message (and
2412 probably the interface on which it is arriving) and not to the outgoing
2413 callout (which could be using a different interface). This has been
2414 changed to use the value of the helo_data option from the smtp transport
2415 instead - this is what is used when a message is actually being sent. If
2416 there is no remote transport (possible with a router that sets up host
2417 addresses), $smtp_active_hostname is used.

14aa5a05 2419PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2420 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2421 (a) The code assumed that strncpy() returns a negative number on buffer
2422 overflow, which isn't the case. Replaced with Exim's string_format()
2423 function.
2424 (b) There were several signed/unsigned issues. I just did the minimum
2425 hacking in of casts. There is scope for a larger refactoring.
2426 (c) The code used strcasecmp() which is not a standard C function.
2427 Replaced with Exim's strcmpic() function.
2428 (d) The code set only $1; it now sets $auth1 as well.
2429 (e) A simple test gave the error "authentication client didn't specify
2430 service in request". It would seem that Dovecot has changed its
2431 interface. Fortunately there's a specification; I followed it and
2432 changed what the client sends and it appears to be working now.

PH
2437PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2438 address A is aliased to B and C, where B exists and C does not. Without
2439 -v the output is "A verified" because verification stops after a
2440 successful redirection if more than one address is generated. However,
2441 with -v the child addresses are also verified. Exim was outputting "A
2442 failed to verify" and then showing the successful verification for C,
2443 with its parentage. It now outputs "B failed to verify", showing B's
2444 parentage before showing the successful verification of C.

2446PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
2447 look up a TXT record in a specific list after matching in a combined
2448 list.
2449
322050c2
PH
2450PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2451 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2452 they consult the DNS. I had assumed they would set it the way they
2453 wanted; and indeed my experiments on Linux seem to show that in some
2454 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2455 To be on the safe side, however, I have now made the interface to
2456 host_find_byname() similar to host_find_bydns(), with an argument
2457 containing the DNS resolver options. The host_find_byname() function now
2458 sets these options at its start, just as host_find_bydns() does. The smtp
2459 transport options dns_qualify_single and dns_search_parents are passed to
2460 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2461 of host_find_byname() use the default settings of RES_DEFNAMES
2462 (qualify_single) but not RES_DNSRCH (search_parents).
2463
08955dd3
PH
2464PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2465 spool_read_header() do less string testing, by means of a preliminary
2466 switch on the second character of optional "-foo" lines. (This is
2467 overdue, caused by the large number of possibilities that now exist.
2468 Originally there were few.) While I was there, I also converted the
2469 str(n)cmp tests so they don't re-test the leading "-" and the first
2470 character, in the hope this might squeeze out yet more improvement.
2471

PH
2472PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2473 flag allowing group syntax was set by the header_syntax check but not
2474 turned off, possible causing trouble later; (2) The flag was not being
2475 set at all for the header_verify test, causing "group"-style headers to
2476 be rejected. I have now set it in this case, and also caused header_
2477 verify to ignore an empty address taken from a group. While doing this, I
2478 came across some other cases where the code for allowing group syntax
2479 while scanning a header line wasn't quite right (mostly, not resetting
2480 the flag correctly in the right place). These bugs could have caused
2481 trouble for malformed header lines. I hope it is now all correct.
2482
602e59e5
PH
2483PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2484 with the "reply" argument non-NULL. The code, however (which originally
2485 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2486 but it didn't always do it. This confused somebody who was copying the
2487 code for some other use. I have removed all the tests.
2488
411ef850
PH
2489PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2490 feature that was used to support insecure browsers during the U.S. crypto
2491 embargo. It requires special client support, and Exim is probably the
2492 only MTA that supported it -- and would never use it because real RSA is
2493 always available. This code has been removed, because it had the bad
2494 effect of slowing Exim down by computing (never used) parameters for the
2495 RSA_EXPORT functionality.
2496
7befa435
PH
2497PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2498 authenticator to fail if there's a tab character in the incoming data
2499 (there should never be unless someone is messing about, as it's supposed
2500 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2501 if the connection is using TLS or if the remote IP is the same as the
2502 local IP, and the "valid-client-cert option" if a client certificate has
2503 been verified.
2504
48da4259 2505PH/22 As suggested by Dennis Davis, added a server_condition option to *all*

PH
2534
2535PH/30 Exim was sometimes attempting to deliver messages that had suffered
2536 address errors (4xx response to RCPT) over the same connection as other
2537 messages routed to the same hosts. Such deliveries are always "forced",
2538 so retry times are not inspected. This resulted in far too many retries
2539 for the affected addresses. The effect occurred only when there were more
2540 hosts than the hosts_max_try setting in the smtp transport when it had
2541 the 4xx errors. Those hosts that it had tried were not added to the list
2542 of hosts for which the message was waiting, so if all were tried, there
2543 was no problem. Two fixes have been applied:
2544
2545 (i) If there are any address or message errors in an SMTP delivery, none
2546 of the hosts (tried or untried) are now added to the list of hosts
2547 for which the message is waiting, so the message should not be a
2548 candidate for sending over the same connection that was used for a
2549 successful delivery of some other message. This seems entirely
2550 reasonable: after all the message is NOT "waiting for some host".
2551 This is so "obvious" that I'm not sure why it wasn't done
2552 previously. Hope I haven't missed anything, but it can't do any
2553 harm, as the worst effect is to miss an optimization.
2554
2555 (ii) If, despite (i), such a delivery is accidentally attempted, the
2556 routing retry time is respected, so at least it doesn't keep
2557 hammering the server.

2568PH/34 The spec says: "With one important exception, whenever a domain list is

520de300
PH
2572PH/35 The error "getsockname() failed: connection reset by peer" was being
2573 written to the panic log as well as the main log, but it isn't really
2574 panic-worthy as it just means the connection died rather early on. I have
2575 removed the panic log writing for the ECONNRESET error when getsockname()
2576 fails.
2577
48c7f9e2
PH
2578PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2579 runs only) independently of the message's sender address. This meant
2580 that, if the 4xx error was in fact related to the sender, a different
2581 message to the same recipient with a different sender could confuse
4c04137d 2582 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2583 server, but other circumstances could also provoke similar problems.
2584 I have changed the default so that the retry time for these errors is now
2585 based a combination of the sender and recipient addresses. This change
2586 can be overridden by setting address_retry_include_sender=false in the
2587 smtp transport.

2589PH/37 For LMTP over TCP/IP (the smtp transport), error responses from the

2858 tcp-wrappers gives "deny", whereas what one would like would be some
2859 kind of temporary error. A kludge has been added to help with this.
2860 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2861 554 error is used if errno is still zero or contains ENOENT (which occurs
2862 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2899PH/01 The code for finding all the local interface addresses on a FreeBSD
2900 system running IPv6 was broken. This may well have applied to all BSD
2901 systems, as well as to others that have similar system calls. The broken
2902 code found IPv4 interfaces correctly, but gave incorrect values for the
2903 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2904 that it would not match correctly against @[] and not recognize the IPv6
2905 addresses as local.

2948 autoreply, Exim could try to deliver to a non-existent relative file
2949 name, causing unrelated and misleading errors. What now happens is that

2984 Instead, it always explicitly searches for A/AAAA records. This avoids
2985 major problems that occur when a DNS server includes only records of one
2986 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2987 fixed another bug: if SRV records were looked up and the corresponding
2988 address records were *not* found in the additional section, the port
2989 values from the SRV records were lost.

PH
2999PH/19 When calculating a retry time, Exim used to measure the "time since
3000 failure" by looking at the "first failed" field in the retry record. Now
3001 it does not use this if it is later than than the arrival time of the
3002 message. Instead it uses the arrival time. This makes for better
3003 behaviour in cases where some deliveries succeed, thus re-setting the
3004 "first failed" field. An example is a quota failure for a huge message
3005 when small messages continue to be delivered. Without this change, the
3006 "time since failure" will always be short, possible causing more frequent
3007 delivery attempts for the huge message than are intended.

3104PH/42 The content-scanning code uses fopen() to create files in which to put
3105 message data. Previously it was not paying any attention to the mode of
3106 the files. Exim runs with umask(0) because the rest of the code creates
3107 files with open(), and sets the required mode explicitly. Thus, these
3108 files were ending up world-writeable. This was not a big issue, because,
3109 being within the spool directory, they were not world-accessible. I have
3110 created a function called modefopen, which takes an additional mode
3111 argument. It sets umask(777), creates the file, chmods it to the required
3112 mode, then resets the umask. All the relevant calls to fopen() in the
3113 content scanning code have been changed to use this function.

3121PH/45 When the plaintext authenticator is running as a client, the server's
3122 challenges are checked to ensure they are valid base64 strings. By
3123 default, the authentication attempt is cancelled if an invalid string is
3124 received. Setting client_ignore_invalid_base64 true ignores these errors.
3125 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
3126 they are received. Thus, the responses can be made to depend on the
3127 challenges. If an invalid string is ignored, an empty string is placed in
3128 the variable.

3139PH/50 When an Exim quota was set without a file count quota, and mailbox_size

3142 of files (along with the size), even though it did not need this
3143 information. It now does the scan only if it needs to find either the
3144 size of the count of files.

3148PH/52 Two bugs concerned with error handling when the smtp transport is
3149 used in LMTP mode:
3150
3151 (i) Exim was not creating retry information for temporary errors given
3152 for individual recipients after the DATA command when the smtp transport
3153 was used in LMTP mode. This meant that they could be retried too
3154 frequently, and not timed out correctly.
3155
3156 (ii) Exim was setting the flag that allows error details to be returned
3157 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3158 recipients that were returned after the DATA command.
3159
3160PH/53 This is related to PH/52, but is more general: for any failing address,
3161 when detailed error information was permitted to be returned to the
3162 sender, but the error was temporary, then after the final timeout, only
3163 "retry timeout exceeded" was returned. Now it returns the full error as
3164 well as "retry timeout exceeded".

3220PH/68 The bounce_return_message and bounce_return_body options were not being
3221 honoured for bounces generated during the reception of non-SMTP messages.
3222 In particular, this applied to messages rejected by the ACL. This bug has
3223 been fixed. However, if bounce_return_message is true and bounce_return_
3224 body is false, the headers that are returned for a non-SMTP message
3225 include only those that have been read before the error was detected.

PH
3234PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3235 function verify_get_ident() calls ip_connect() to connect a socket, but
3236 if the "connect()" function timed out, ip_connect() used to close the
3237 socket. However, verify_get_ident() also closes the socket later, and in
3238 between Exim writes to the log, which may get opened at this point. When
3239 the socket was closed in ip_connect(), the log could get the same file
3240 descriptor number as the socket. This naturally causes chaos. The fix is
3241 not to close the socket in ip_connect(); the socket should be closed by
3242 the function that creates it. There was only one place in the code where
3243 this was missing, in the iplookup router, which I don't think anybody now
3244 uses, but I've fixed it anyway.

3263PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3264
3265 (1) Generate an error if the third argument for the ${prvs expansion is
3266 not a single digit.
3267
3268 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3269 string.
3270
3271 (3) Reset the variables that are obtained from the first argument of
3272 ${prvscheck and used in the second argument before leaving the code,
3273 because their memory is reclaimed, so using them afterwards may do
3274 silly things.
3275
3276 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3277 one (it's much easier than Tom thought :-).
3278
3279 (5) Because of (4), we can now allow for the use of $prvscheck_result
3280 inside the third argument.
