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.
875512a3 28

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.
36

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 +).

49PP/03 Add $SOURCE_DATE_EPOCH support for reproducible builds, per spec at
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.
63
eeb35890
JH
64JH/10 Enable use of sendfile in Linux builds as default. It was disabled in
65 4.77 as the kernel support then wasn't solid, having issues in 64bit
66 mode. Now, it's been long enough.

JH
83JH/04 Bug 2004: fix CHUNKING in non-PIPELINEING mode. Chunk data following
84 close after a BDAT command line could be taken as a following command,
85 giving a synch failure. Fix by only checking for synch immediately
86 before acknowledging the chunk.

88PP/02 GitHub PR 52: many spelling fixes, which include fixing parsing of
89 no_require_dnssec option and creation of _HAVE_TRANSPORT_APPEND_MAILDIR
90 macro. Patches provided by Josh Soref.
91
bd8fbe36
JH
92JH/05 Have the EHLO response advertise VRFY, if there is a vrfy ACL defined.
93 Previously we did not; the RFC seems ambiguous and VRFY is not listed
94 by IANA as a service extension. However, John Klensin suggests that we
95 should.
96
97JH/06 Bug 2017: Fix DKIM verification in -bh test mode. The data feed into

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

bd8fbe36 101JH/07 Rationalise the coding for callout smtp conversations and transport ones.
902fbd69
JH
102 As a side-benfit, callouts can now use PIPELINING hence fewer round-trips.
103
bd8fbe36
JH
104JH/08 Bug 2016: Fix DKIM verification vs. CHUNKING. Any BDAT commands after
105 the first were themselves being wrongly included in the feed into dkim
106 processing; with most chunk sizes in use this resulted in an incorrect
107 body hash calculated value.
108
eea19017
JH
109JH/09 Bug 2014: permit inclusion of a DKIM-Signature header in a received
110 DKIM signature block, for verification. Although advised against by
111 standards it is specifically not ruled illegal.

JH
113JH/10 Bug 2025: Fix reception of (quoted) local-parts with embedded spaces.
114
115JH/11 Bug 2029: Fix crash in DKIM verification when a message signature block is
116 missing a body hash (the bh= tag).
117
118JH/12 Bug 2018: Re-order Proxy Protocol startup versus TLS-on-connect startup.
119 It seems that HAProxy sends the Proxy Protocol information in clear and
120 only then does a TLS startup, so do the same.
121
122JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
123 TCP connections (such as for Spamd) unless the daemon successfully set
124 Fast Open mode on its listening sockets. This fixes breakage seen on
125 too-old kernels or those not configured for Fast Open, at the cost of
126 requiring both directions being enabled for TFO, and TFO never being used
127 by non-daemon-related Exim processes.
128
129JH/14 Bug 2000: Reject messages recieved with CHUNKING but with malformed line
130 endings, at least on the first header line. Try to canonify any that get
131 past that check, despite the cost.
132
b6040544
JH
133JH/15 Angle-bracket nesting (an error inserted by broken sendmails) levels are
134 now limited to an arbitrary five deep, while parsing addresses with the
135 strip_excess_angle_brackets option enabled.

PP
137PP/03 Bug 2018: For Proxy Protocol and TLS-on-connect, do not over-read and
138 instead leave the unprompted TLS handshake in socket buffer for the
139 TLS library to consume.

143PP/05 FreeBSD compat: handle that Ports no longer create /usr/bin/perl
144
90341c71
JH
145JH/16 Drop variables when they go out of scope. Memory management drops a whole
146 region in one operation, for speed, and this leaves assigned pointers
147 dangling. Add checks run only under the testsuite which checks all
148 variables at a store-reset and panics on a dangling pointer; add code
149 explicitly nulling out all the variables discovered. Fixes one known
150 bug: a transport crash, where a dangling pointer for $sending_ip_address
151 originally assigned in a verify callout, is re-used.
152

PP
153PP/06 Drop '.' from @INC in various Perl scripts.
154
155PP/07 Switch FreeBSD iconv to always use the base-system libc functions.
156
157PP/08 Reduce a number of compilation warnings under clang; building with
158 CC=clang CFLAGS+=-Wno-dangling-else -Wno-logical-op-parentheses
159 should be warning-free.

164 realloc(NULL) is not equivalent to malloc() [SunOS et al].

181JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
182 supports it and a size is available (ie. the sending peer gave us one).
8d042305 183
03d5892b
JH
184JH/02 The obsolete acl condition "demime" is removed (finally, after ten
185 years of being deprecated). The replacements are the ACLs
186 acl_smtp_mime and acl_not_smtp_mime.
187
4b0fe319
JH
188JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
189 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
190 or even an in-clear connection were permitted. Now, if the host lookup
191 was dnssec and dane was requested then the host is only used if the
192 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
193 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
194 if one fails this test.
195 This means that a poorly-configured remote DNS will make it incommunicado;
196 but it protects against a DNS-interception attack on it.

98c82a3d
JH
218JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
219 a cutthrough deliver is pending, as we always want to make a connection.
220 This also avoids re-routing the message when later placing the cutthrough
221 connection after a verify cache hit.
222 Do not update it with the verify result either.
223
224JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
225 when routing results in more than one destination address.
226
ae8386f0
JH
227JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
228 signing (which inhibits the cutthrough capability). Previously only
229 the presence of an option was tested; now an expansion evaluating as
230 empty is permissible (obviously it should depend only on data available
231 when the cutthrough connection is made).

4c04137d 401 with TLS, default unset, mainly to enable keeping the testsuite sane.

402 If a server certificate is not supplied (via tls_certificate) an error is

406 at installation time.

411JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
412 in transport context, after the attempt, and per-recipient. The latter type
413 is per host attempted. The event data is the error message, and the errno
414 information encodes the lookup type (A vs. MX) used for the (first) host,
4c04137d 415 and the trailing two digits of the smtp 4xx response.

1010TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
1011
1012 When a queue runner is handling a message, Exim first routes the
1013 recipient addresses, during which it prunes them based on the retry
1014 hints database. After that it attempts to deliver the message to
1015 any remaining recipients. It then updates the hints database using
1016 the retry rules.
1017
1018 So if a recipient address works intermittently, it can get repeatedly
1019 deferred at routing time. The retry hints record remains fresh so the
1020 address never reaches the final cutoff time.
1021
1022 This is a fairly common occurrence when a user is bumping up against
1023 their storage quota. Exim had some logic in its local delivery code
1024 to deal with this. However it did not apply to per-recipient defers
1025 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1026
1ddeb334
TF
1027 This change adds a proper retry rule check during routing so that the
1028 final cutoff time is checked against the message's age. We only do
1029 this check if there is an address retry record and there is not a
1030 domain retry record; this implies that previous attempts to handle
1031 the address had the retry_use_local_parts option turned on. We use
1032 this as an approximation for the destination being like a local
1033 delivery, as in LMTP.
67bd1ab3
TF
1034
1035 I suspect this new check makes the old local delivery cutoff check
1036 redundant, but I have not verified this so I left the code in place.

TF
1358TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1359 lock up or crash if it happened to be inside a call to libc when it
1360 got a SIGUSR1 from exiwhat.
1361
1362 The SIGUSR1 handler appends the current process status to the process
1363 log which is later printed by exiwhat. It used to use the general
1364 purpose logging code to do this, but several functions it calls are
1365 not safe for signals.
1366
1367 The new output code in the SIGUSR1 handler is specific to the process
1368 log, and simple enough that it's easy to inspect for signal safety.
1369 Removing some special cases also simplifies the general logging code.
1370 Removing the spurious timestamps from the process log simplifies
1371 exiwhat.
1372
c99ce5c9
TF
1373TF/04 Improved ratelimit ACL condition.
1374
1375 The /noupdate option has been deprecated in favour of /readonly which
1376 has clearer semantics. The /leaky, /strict, and /readonly update modes
1377 are mutually exclusive. The update mode is no longer included in the
1378 database key; it just determines when the database is updated. (This
4c04137d 1379 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1380
1381 Exim now checks that the per_* options are used with an update mode that
1382 makes sense for the current ACL. For example, when Exim is processing a
1383 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1384 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1385 must specify per_mail/readonly. If you omit the update mode it defaults to
1386 /leaky where that makes sense (as before) or /readonly where required.
1387
1388 The /noupdate option is now undocumented but still supported for
1389 backwards compatibility. It is equivalent to /readonly except that in
1390 ACLs where /readonly is required you may specify /leaky/noupdate or
1391 /strict/noupdate which are treated the same as /readonly.
1392
1393 A useful new feature is the /count= option. This is a generalization
1394 of the per_byte option, so that you can measure the throughput of other
1395 aggregate values. For example, the per_byte option is now equivalent
1396 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1397
1398 The per_rcpt option has been generalized using the /count= mechanism
1399 (though it's more complicated than the per_byte equivalence). When it is
1400 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1401 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1402 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1403 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1404 Note that using per_rcpt with a non-readonly update mode in more than
1405 one ACL will cause the recipients to be double-counted. (The per_mail
1406 and per_byte options don't have this problem.)
1407
1408 The handling of very low rates has changed slightly. If the computed rate
1409 is less than the event's count (usually one) then this event is the first
1410 after a long gap. In this case the rate is set to the same as this event's
1411 count, so that the first message of a spam run is counted properly.
1412
1413 The major new feature is a mechanism for counting the rate of unique
1414 events. The new per_addr option counts the number of different
1415 recipients that someone has sent messages to in the last time period. It
1416 behaves like per_rcpt if all the recipient addresses are different, but
1417 duplicate recipient addresses do not increase the measured rate. Like
1418 the /count= option this is a general mechanism, so the per_addr option
1419 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1420 example, measure the rate that a client uses different sender addresses
1421 with the options per_mail/unique=$sender_address. There are further
1422 details in the main documentation.

1973 were called 'true' and it seems that C99 defines that as a reserved

1992-----------------
1993
1994PH/01 Another patch from the Sieve maintainer.
1995
6a3bceb1
PH
1996PH/02 When an IPv6 address is converted to a string for single-key lookup
1997 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1998 dots are used instead of colons so that keys in lsearch files need not
1999 contain colons. This was done some time before quoting was made available
2000 in lsearch files. However, iplsearch files do require colons in IPv6 keys
2001 (notated using the quote facility) so as to distinguish them from IPv4
2002 keys. This meant that lookups for IP addresses in host lists did not work
2003 for iplsearch lookups.
2004
2005 This has been fixed by arranging for IPv6 addresses to be expressed with
2006 colons if the lookup type is iplsearch. This is not incompatible, because
2007 previously such lookups could never work.
2008
4c04137d 2009 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2010 ordinary lsearch keys. However, making the change in all cases is
2011 incompatible and would probably break a number of configurations.

MH
2016MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2017 conversion specification without a maximum field width, thereby enabling
2018 a rogue spamd server to cause a buffer overflow. While nobody in their
2019 right mind would setup Exim to query an untrusted spamd server, an
2020 attacker that gains access to a server running spamd could potentially
2021 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
2026MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2027 a directory entry by the name of the lookup key. Previously, if a
2028 symlink pointed to a non-existing file or a file in a directory that
2029 Exim lacked permissions to read, a lookup for a key matching that
2030 symlink would fail. Now it is enough that a matching directory entry
2031 exists, symlink or not. (Bugzilla 503.)

2104PH/02 In an ACL statement such as

2108 if a client was not listed at all, or was listed with a value other than
2109 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
2110 the condition was not true (as it should be), so access was not denied.

a14e5636
PH
2214PH/29 SMTP synchronization checks are implemented when a command is read -
2215 there is a check that no more input is waiting when there shouldn't be
2216 any. However, for some commands, a delay in an ACL can mean that it is
2217 some time before the response is written. In this time, more input might
2218 arrive, invalidly. So now there are extra checks after an ACL has run for
2219 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2220 pipelining has not been advertised.

PH
2232PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in

2234 SSL_CTX_set_info_callback() might give an error value. In fact, there is
2235 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
2236 was a macro that became an assignment, so it seemed to work. This has
2237 changed to a proper function call with a void return, hence the compile
2238 error. Exim's code has been fixed.

2269 started the daemon, but after a SIGHUP it used the Exim user (because it

2276 with PIPELINING or a stupid MUA), the error message that was given to the

PH
2294 the response to the final '.' that terminates a message, but only in the
2295 case where the client has not sent further data following the '.'
2296 (unfortunately, this is allowed). However, in many cases there won't be
2297 any further data because there won't be any more messages to send. A call
2298 to select() can be used: if it shows that the input is "ready", there is
2299 either input waiting, or the socket has been closed. An attempt to read
2300 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2301 would have sent an OK response which the client would never have see.

2309Exim version 4.66
2310-----------------
2311
2312PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2313 fixed by 4.65/MH/01 (is this a record?) are fixed:
2314
2315 (i) An empty string was always treated as zero by the numeric comparison
2316 operators. This behaviour has been restored.
2317
2318 (ii) It is documented that the numeric comparison operators always treat
2319 their arguments as decimal numbers. This was broken in that numbers
2320 starting with 0 were being interpreted as octal.
2321
2322 While fixing these problems I realized that there was another issue that
2323 hadn't been noticed. Values of message_size_limit (both the global option
2324 and the transport option) were treated as octal if they started with 0.
2325 The documentation was vague. These values are now always treated as
2326 decimal, and I will make that clear in the documentation.

PH
2340PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
2341 child addresses, Exim now panics and dies. Previously, because the count
2342 is held in a short int, deliveries were likely to be lost. As such a
2343 large number of recipients for a single message is ridiculous
2344 (performance will be very, very poor), I have chosen to impose a limit
2345 rather than extend the field.

2351TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2352 leftover -K file (the existence of which was triggered by #402).
2353 While we were at it, introduced process PID as part of the -K
2354 filename. This should rule out race conditions when creating
2355 these files.
2356
2357TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
2358 processing considerably. Previous code took too long for large mails,
2359 triggering a timeout which in turn triggers #401.
2360
2361TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
2362 in the DK code in transports.c. sendfile() is not really portable,
2363 hence the _LINUX specificness.

2365TF/01 In the add_headers option to the mail command in an Exim filter,

2367 header after the first one which had an odd number of characters
2368 in the field name.

PH
2370PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2371 callout verification, Exim cached a "reject" for the entire domain. This
2372 is correct for most verifications, but it is not correct for a recipient
2373 verification with use_sender or use_postmaster set, because in that case
2374 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2375 case of MAIL FROM:<> rejection from other early rejections (e.g.
2376 rejection of HELO). When verifying a recipient using a non-null MAIL
2377 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2378 Whatever the result of the callout, the value of the domain cache is
2379 left unchanged (for any other kind of callout, getting as far as trying
2380 RCPT means that the domain itself is ok).

2414PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2415 hostname. This is wrong, because it relates to the incoming message (and
2416 probably the interface on which it is arriving) and not to the outgoing
2417 callout (which could be using a different interface). This has been
2418 changed to use the value of the helo_data option from the smtp transport
2419 instead - this is what is used when a message is actually being sent. If
2420 there is no remote transport (possible with a router that sets up host
2421 addresses), $smtp_active_hostname is used.

14aa5a05 2423PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2424 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2425 (a) The code assumed that strncpy() returns a negative number on buffer
2426 overflow, which isn't the case. Replaced with Exim's string_format()
2427 function.
2428 (b) There were several signed/unsigned issues. I just did the minimum
2429 hacking in of casts. There is scope for a larger refactoring.
2430 (c) The code used strcasecmp() which is not a standard C function.
2431 Replaced with Exim's strcmpic() function.
2432 (d) The code set only $1; it now sets $auth1 as well.
2433 (e) A simple test gave the error "authentication client didn't specify
2434 service in request". It would seem that Dovecot has changed its
2435 interface. Fortunately there's a specification; I followed it and
2436 changed what the client sends and it appears to be working now.

2441PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2442 address A is aliased to B and C, where B exists and C does not. Without
2443 -v the output is "A verified" because verification stops after a
2444 successful redirection if more than one address is generated. However,
2445 with -v the child addresses are also verified. Exim was outputting "A
2446 failed to verify" and then showing the successful verification for C,
2447 with its parentage. It now outputs "B failed to verify", showing B's
2448 parentage before showing the successful verification of C.

2450PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
2451 look up a TXT record in a specific list after matching in a combined
2452 list.
2453
322050c2
PH
2454PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2455 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2456 they consult the DNS. I had assumed they would set it the way they
2457 wanted; and indeed my experiments on Linux seem to show that in some
2458 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2459 To be on the safe side, however, I have now made the interface to
2460 host_find_byname() similar to host_find_bydns(), with an argument
2461 containing the DNS resolver options. The host_find_byname() function now
2462 sets these options at its start, just as host_find_bydns() does. The smtp
2463 transport options dns_qualify_single and dns_search_parents are passed to
2464 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2465 of host_find_byname() use the default settings of RES_DEFNAMES
2466 (qualify_single) but not RES_DNSRCH (search_parents).

PH
2468PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2469 spool_read_header() do less string testing, by means of a preliminary
2470 switch on the second character of optional "-foo" lines. (This is
2471 overdue, caused by the large number of possibilities that now exist.
2472 Originally there were few.) While I was there, I also converted the
2473 str(n)cmp tests so they don't re-test the leading "-" and the first
2474 character, in the hope this might squeeze out yet more improvement.

PH
2476PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2477 flag allowing group syntax was set by the header_syntax check but not
2478 turned off, possible causing trouble later; (2) The flag was not being
2479 set at all for the header_verify test, causing "group"-style headers to
2480 be rejected. I have now set it in this case, and also caused header_
2481 verify to ignore an empty address taken from a group. While doing this, I
2482 came across some other cases where the code for allowing group syntax
2483 while scanning a header line wasn't quite right (mostly, not resetting
2484 the flag correctly in the right place). These bugs could have caused
2485 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
2487PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2488 with the "reply" argument non-NULL. The code, however (which originally
2489 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2490 but it didn't always do it. This confused somebody who was copying the
2491 code for some other use. I have removed all the tests.
2492
411ef850
PH
2493PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2494 feature that was used to support insecure browsers during the U.S. crypto
2495 embargo. It requires special client support, and Exim is probably the
2496 only MTA that supported it -- and would never use it because real RSA is
2497 always available. This code has been removed, because it had the bad
2498 effect of slowing Exim down by computing (never used) parameters for the
2499 RSA_EXPORT functionality.

7befa435
PH
2501PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2502 authenticator to fail if there's a tab character in the incoming data
2503 (there should never be unless someone is messing about, as it's supposed
2504 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2505 if the connection is using TLS or if the remote IP is the same as the
2506 local IP, and the "valid-client-cert option" if a client certificate has
2507 been verified.

PH
2538
2539PH/30 Exim was sometimes attempting to deliver messages that had suffered
2540 address errors (4xx response to RCPT) over the same connection as other
2541 messages routed to the same hosts. Such deliveries are always "forced",
2542 so retry times are not inspected. This resulted in far too many retries
2543 for the affected addresses. The effect occurred only when there were more
2544 hosts than the hosts_max_try setting in the smtp transport when it had
2545 the 4xx errors. Those hosts that it had tried were not added to the list
2546 of hosts for which the message was waiting, so if all were tried, there
2547 was no problem. Two fixes have been applied:
2548
2549 (i) If there are any address or message errors in an SMTP delivery, none
2550 of the hosts (tried or untried) are now added to the list of hosts
2551 for which the message is waiting, so the message should not be a
2552 candidate for sending over the same connection that was used for a
2553 successful delivery of some other message. This seems entirely
2554 reasonable: after all the message is NOT "waiting for some host".
2555 This is so "obvious" that I'm not sure why it wasn't done
2556 previously. Hope I haven't missed anything, but it can't do any
2557 harm, as the worst effect is to miss an optimization.
2558
2559 (ii) If, despite (i), such a delivery is accidentally attempted, the
2560 routing retry time is respected, so at least it doesn't keep
2561 hammering the server.

2576PH/35 The error "getsockname() failed: connection reset by peer" was being
2577 written to the panic log as well as the main log, but it isn't really
2578 panic-worthy as it just means the connection died rather early on. I have
2579 removed the panic log writing for the ECONNRESET error when getsockname()
2580 fails.
2581
48c7f9e2
PH
2582PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2583 runs only) independently of the message's sender address. This meant
2584 that, if the 4xx error was in fact related to the sender, a different
2585 message to the same recipient with a different sender could confuse
4c04137d 2586 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2587 server, but other circumstances could also provoke similar problems.
2588 I have changed the default so that the retry time for these errors is now
2589 based a combination of the sender and recipient addresses. This change
2590 can be overridden by setting address_retry_include_sender=false in the
2591 smtp transport.

2859PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2861 Unfortunately, if there is a major crisis, such as a disk failure,
2862 tcp-wrappers gives "deny", whereas what one would like would be some
2863 kind of temporary error. A kludge has been added to help with this.
2864 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2865 554 error is used if errno is still zero or contains ENOENT (which occurs
2866 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2867 451 error is used.

2901-----------------

2903PH/01 The code for finding all the local interface addresses on a FreeBSD
2904 system running IPv6 was broken. This may well have applied to all BSD
2905 systems, as well as to others that have similar system calls. The broken
2906 code found IPv4 interfaces correctly, but gave incorrect values for the
2907 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2908 that it would not match correctly against @[] and not recognize the IPv6
2909 addresses as local.

2951 generate an autoreply, and therefore failed to obtain an address for the
2952 autoreply, Exim could try to deliver to a non-existent relative file
2953 name, causing unrelated and misleading errors. What now happens is that

2986PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2987 additional section of a DNS packet that returns MX or SRV records.
2988 Instead, it always explicitly searches for A/AAAA records. This avoids
2989 major problems that occur when a DNS server includes only records of one
2990 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2991 fixed another bug: if SRV records were looked up and the corresponding
2992 address records were *not* found in the additional section, the port
2993 values from the SRV records were lost.

2995PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

3002
727071f8
PH
3003PH/19 When calculating a retry time, Exim used to measure the "time since
3004 failure" by looking at the "first failed" field in the retry record. Now
3005 it does not use this if it is later than than the arrival time of the
3006 message. Instead it uses the arrival time. This makes for better
3007 behaviour in cases where some deliveries succeed, thus re-setting the
3008 "first failed" field. An example is a quota failure for a huge message
3009 when small messages continue to be delivered. Without this change, the
3010 "time since failure" will always be short, possible causing more frequent
3011 delivery attempts for the huge message than are intended.

3079PH/36 Now that the new test suite is complete, we can remove some of the
3080 special code in Exim that was needed for the old test suite. For example,
3081 sorting DNS records because real resolvers return them in an arbitrary
3082 order. The new test suite's fake resolver always returns records in the
3083 same order.
3084
3085PH/37 When running in the test harness, use -odi for submitted messages (e.g.
3086 bounces) except when queue_only is set, to avoid logging races between
3087 the different processes.

3093JJ/03 exipick: Removed parentheses from 'next' and 'last' calls that specified
3094 a label. They prevented compilation on older perls.

3097 a warning to be raised on newish perls.

3099JJ/05 exipick: Fixed bug where -bpc always showed a count of all messages
3100 on queue. Changes to match documented behaviour of showing count of
3101 messages matching specified criteria.

PH
3108PH/42 The content-scanning code uses fopen() to create files in which to put
3109 message data. Previously it was not paying any attention to the mode of
3110 the files. Exim runs with umask(0) because the rest of the code creates
3111 files with open(), and sets the required mode explicitly. Thus, these
3112 files were ending up world-writeable. This was not a big issue, because,
3113 being within the spool directory, they were not world-accessible. I have
3114 created a function called modefopen, which takes an additional mode
3115 argument. It sets umask(777), creates the file, chmods it to the required
3116 mode, then resets the umask. All the relevant calls to fopen() in the
3117 content scanning code have been changed to use this function.

PH
3125PH/45 When the plaintext authenticator is running as a client, the server's
3126 challenges are checked to ensure they are valid base64 strings. By
3127 default, the authentication attempt is cancelled if an invalid string is
3128 received. Setting client_ignore_invalid_base64 true ignores these errors.
3129 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
3130 they are received. Thus, the responses can be made to depend on the
3131 challenges. If an invalid string is ignored, an empty string is placed in
3132 the variable.

PH
3143PH/50 When an Exim quota was set without a file count quota, and mailbox_size
3144 was also set, the appendfile transport was unnecessarily scanning a
3145 directory of message files (e.g. for maildir delivery) to find the count
3146 of files (along with the size), even though it did not need this
3147 information. It now does the scan only if it needs to find either the
3148 size of the count of files.

3152PH/52 Two bugs concerned with error handling when the smtp transport is
3153 used in LMTP mode:
3154
3155 (i) Exim was not creating retry information for temporary errors given
3156 for individual recipients after the DATA command when the smtp transport
3157 was used in LMTP mode. This meant that they could be retried too
3158 frequently, and not timed out correctly.
3159
3160 (ii) Exim was setting the flag that allows error details to be returned
3161 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3162 recipients that were returned after the DATA command.
3163
3164PH/53 This is related to PH/52, but is more general: for any failing address,
3165 when detailed error information was permitted to be returned to the
3166 sender, but the error was temporary, then after the final timeout, only
3167 "retry timeout exceeded" was returned. Now it returns the full error as
3168 well as "retry timeout exceeded".

3224PH/68 The bounce_return_message and bounce_return_body options were not being
3225 honoured for bounces generated during the reception of non-SMTP messages.
3226 In particular, this applied to messages rejected by the ACL. This bug has
3227 been fixed. However, if bounce_return_message is true and bounce_return_
3228 body is false, the headers that are returned for a non-SMTP message
3229 include only those that have been read before the error was detected.

PH
3238PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3239 function verify_get_ident() calls ip_connect() to connect a socket, but
3240 if the "connect()" function timed out, ip_connect() used to close the
3241 socket. However, verify_get_ident() also closes the socket later, and in
3242 between Exim writes to the log, which may get opened at this point. When
3243 the socket was closed in ip_connect(), the log could get the same file
3244 descriptor number as the socket. This naturally causes chaos. The fix is
3245 not to close the socket in ip_connect(); the socket should be closed by
3246 the function that creates it. There was only one place in the code where
3247 this was missing, in the iplookup router, which I don't think anybody now
3248 uses, but I've fixed it anyway.

3267PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3268
3269 (1) Generate an error if the third argument for the ${prvs expansion is
3270 not a single digit.
3271
3272 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3273 string.
3274
3275 (3) Reset the variables that are obtained from the first argument of
3276 ${prvscheck and used in the second argument before leaving the code,
3277 because their memory is reclaimed, so using them afterwards may do
3278 silly things.
3279
3280 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3281 one (it's much easier than Tom thought :-).
