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

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
5e6d12ac
JH
27 cipher, Certificate or OCSP information. A "continued-TLS" marker is
28 added instead of the cipher information: "X=*".

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

JH
53JH/04 Bug 2004: fix CHUNKING in non-PIPELINEING mode. Chunk data following
54 close after a BDAT command line could be taken as a following command,
55 giving a synch failure. Fix by only checking for synch immediately
56 before acknowledging the chunk.

58PP/02 GitHub PR 52: many spelling fixes, which include fixing parsing of

60 macro. Patches provided by Josh Soref.

JH
62JH/05 Have the EHLO response advertise VRFY, if there is a vrfy ACL defined.
63 Previously we did not; the RFC seems ambiguous and VRFY is not listed
64 by IANA as a service extension. However, John Klensin suggests that we
65 should.
66
67JH/06 Bug 2017: Fix DKIM verification in -bh test mode. The data feed into
b895f4b2
JH
68 the dkim code may be unix-mode line endings rather than smtp wire-format
69 CRLF, so prepend a CR to any bare LF.
fd047340 70
bd8fbe36 71JH/07 Rationalise the coding for callout smtp conversations and transport ones.
902fbd69
JH
72 As a side-benfit, callouts can now use PIPELINING hence fewer round-trips.
73
bd8fbe36
JH
74JH/08 Bug 2016: Fix DKIM verification vs. CHUNKING. Any BDAT commands after
75 the first were themselves being wrongly included in the feed into dkim
76 processing; with most chunk sizes in use this resulted in an incorrect
77 body hash calculated value.
78
eea19017
JH
79JH/09 Bug 2014: permit inclusion of a DKIM-Signature header in a received
80 DKIM signature block, for verification. Although advised against by
81 standards it is specifically not ruled illegal.
82

JH
83JH/10 Bug 2025: Fix reception of (quoted) local-parts with embedded spaces.
84
85JH/11 Bug 2029: Fix crash in DKIM verification when a message signature block is
86 missing a body hash (the bh= tag).
87
88JH/12 Bug 2018: Re-order Proxy Protocol startup versus TLS-on-connect startup.
89 It seems that HAProxy sends the Proxy Protocol information in clear and
90 only then does a TLS startup, so do the same.
91
92JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
93 TCP connections (such as for Spamd) unless the daemon successfully set
94 Fast Open mode on its listening sockets. This fixes breakage seen on
95 too-old kernels or those not configured for Fast Open, at the cost of
96 requiring both directions being enabled for TFO, and TFO never being used
97 by non-daemon-related Exim processes.
98
99JH/14 Bug 2000: Reject messages recieved with CHUNKING but with malformed line
100 endings, at least on the first header line. Try to canonify any that get
101 past that check, despite the cost.
102

103JH/15 Angle-bracket nesting (an error inserted by broken sendmails) levels are
104 now limited to an arbitrary five deep, while parsing addresses with the
105 strip_excess_angle_brackets option enabled.

107PP/03 Bug 2018: For Proxy Protocol and TLS-on-connect, do not over-read and
108 instead leave the unprompted TLS handshake in socket buffer for the

114
90341c71
JH
115JH/16 Drop variables when they go out of scope. Memory management drops a whole
116 region in one operation, for speed, and this leaves assigned pointers
117 dangling. Add checks run only under the testsuite which checks all
118 variables at a store-reset and panics on a dangling pointer; add code
119 explicitly nulling out all the variables discovered. Fixes one known
120 bug: a transport crash, where a dangling pointer for $sending_ip_address
121 originally assigned in a verify callout, is re-used.

151JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
152 supports it and a size is available (ie. the sending peer gave us one).
8d042305 153
03d5892b
JH
154JH/02 The obsolete acl condition "demime" is removed (finally, after ten
155 years of being deprecated). The replacements are the ACLs
156 acl_smtp_mime and acl_not_smtp_mime.
157
4b0fe319
JH
158JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
159 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
160 or even an in-clear connection were permitted. Now, if the host lookup
161 was dnssec and dane was requested then the host is only used if the
162 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
163 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
164 if one fails this test.
165 This means that a poorly-configured remote DNS will make it incommunicado;
166 but it protects against a DNS-interception attack on it.

JH
188JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
189 a cutthrough deliver is pending, as we always want to make a connection.
190 This also avoids re-routing the message when later placing the cutthrough
191 connection after a verify cache hit.
192 Do not update it with the verify result either.
193
194JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
195 when routing results in more than one destination address.
196
ae8386f0
JH
197JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
198 signing (which inhibits the cutthrough capability). Previously only
199 the presence of an option was tested; now an expansion evaluating as
200 empty is permissible (obviously it should depend only on data available
201 when the cutthrough connection is made).

980TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
981
982 When a queue runner is handling a message, Exim first routes the
983 recipient addresses, during which it prunes them based on the retry
984 hints database. After that it attempts to deliver the message to
985 any remaining recipients. It then updates the hints database using
986 the retry rules.
987
988 So if a recipient address works intermittently, it can get repeatedly
989 deferred at routing time. The retry hints record remains fresh so the
990 address never reaches the final cutoff time.
991
992 This is a fairly common occurrence when a user is bumping up against
993 their storage quota. Exim had some logic in its local delivery code
994 to deal with this. However it did not apply to per-recipient defers
995 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
996
1ddeb334
TF
997 This change adds a proper retry rule check during routing so that the
998 final cutoff time is checked against the message's age. We only do
999 this check if there is an address retry record and there is not a
1000 domain retry record; this implies that previous attempts to handle
1001 the address had the retry_use_local_parts option turned on. We use
1002 this as an approximation for the destination being like a local
1003 delivery, as in LMTP.
67bd1ab3
TF
1004
1005 I suspect this new check makes the old local delivery cutoff check
1006 redundant, but I have not verified this so I left the code in place.

1014 When I ran the test suite under the user fanf2, Exim expanded
1015 the header to contain my full name, whereas it should have added
1016 a Resent-Sender: header. It erroneously treats any prefix of the
1017 username as equal to the username.

1044 advertises the facility. If the client requests PRDR a new

1046 the body content is received and before the acl_smtp_data ACL.

TF
1328TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1329 lock up or crash if it happened to be inside a call to libc when it
1330 got a SIGUSR1 from exiwhat.
1331
1332 The SIGUSR1 handler appends the current process status to the process
1333 log which is later printed by exiwhat. It used to use the general
1334 purpose logging code to do this, but several functions it calls are
1335 not safe for signals.
1336
1337 The new output code in the SIGUSR1 handler is specific to the process
1338 log, and simple enough that it's easy to inspect for signal safety.
1339 Removing some special cases also simplifies the general logging code.
1340 Removing the spurious timestamps from the process log simplifies
1341 exiwhat.
1342
c99ce5c9
TF
1343TF/04 Improved ratelimit ACL condition.
1344
1345 The /noupdate option has been deprecated in favour of /readonly which
1346 has clearer semantics. The /leaky, /strict, and /readonly update modes
1347 are mutually exclusive. The update mode is no longer included in the
1348 database key; it just determines when the database is updated. (This
4c04137d 1349 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1350
1351 Exim now checks that the per_* options are used with an update mode that
1352 makes sense for the current ACL. For example, when Exim is processing a
1353 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1354 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1355 must specify per_mail/readonly. If you omit the update mode it defaults to
1356 /leaky where that makes sense (as before) or /readonly where required.
1357
1358 The /noupdate option is now undocumented but still supported for
1359 backwards compatibility. It is equivalent to /readonly except that in
1360 ACLs where /readonly is required you may specify /leaky/noupdate or
1361 /strict/noupdate which are treated the same as /readonly.
1362
1363 A useful new feature is the /count= option. This is a generalization
1364 of the per_byte option, so that you can measure the throughput of other
1365 aggregate values. For example, the per_byte option is now equivalent
1366 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1367
1368 The per_rcpt option has been generalized using the /count= mechanism
1369 (though it's more complicated than the per_byte equivalence). When it is
1370 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1371 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1372 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1373 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1374 Note that using per_rcpt with a non-readonly update mode in more than
1375 one ACL will cause the recipients to be double-counted. (The per_mail
1376 and per_byte options don't have this problem.)
1377
1378 The handling of very low rates has changed slightly. If the computed rate
1379 is less than the event's count (usually one) then this event is the first
1380 after a long gap. In this case the rate is set to the same as this event's
1381 count, so that the first message of a spam run is counted properly.
1382
1383 The major new feature is a mechanism for counting the rate of unique
1384 events. The new per_addr option counts the number of different
1385 recipients that someone has sent messages to in the last time period. It
1386 behaves like per_rcpt if all the recipient addresses are different, but
1387 duplicate recipient addresses do not increase the measured rate. Like
1388 the /count= option this is a general mechanism, so the per_addr option
1389 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1390 example, measure the rate that a client uses different sender addresses
1391 with the options per_mail/unique=$sender_address. There are further
1392 details in the main documentation.

1963
1964PH/01 Another patch from the Sieve maintainer.
1965
6a3bceb1
PH
1966PH/02 When an IPv6 address is converted to a string for single-key lookup
1967 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1968 dots are used instead of colons so that keys in lsearch files need not
1969 contain colons. This was done some time before quoting was made available
1970 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1971 (notated using the quote facility) so as to distinguish them from IPv4
1972 keys. This meant that lookups for IP addresses in host lists did not work
1973 for iplsearch lookups.
1974
1975 This has been fixed by arranging for IPv6 addresses to be expressed with
1976 colons if the lookup type is iplsearch. This is not incompatible, because
1977 previously such lookups could never work.
1978
4c04137d 1979 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
1980 ordinary lsearch keys. However, making the change in all cases is
1981 incompatible and would probably break a number of configurations.

MH
1986MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1987 conversion specification without a maximum field width, thereby enabling
1988 a rogue spamd server to cause a buffer overflow. While nobody in their
1989 right mind would setup Exim to query an untrusted spamd server, an
1990 attacker that gains access to a server running spamd could potentially
1991 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
1996MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1997 a directory entry by the name of the lookup key. Previously, if a
1998 symlink pointed to a non-existing file or a file in a directory that
1999 Exim lacked permissions to read, a lookup for a key matching that
2000 symlink would fail. Now it is enough that a matching directory entry
2001 exists, symlink or not. (Bugzilla 503.)

2184PH/29 SMTP synchronization checks are implemented when a command is read -
2185 there is a check that no more input is waiting when there shouldn't be

2187 some time before the response is written. In this time, more input might
2188 arrive, invalidly. So now there are extra checks after an ACL has run for
2189 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2190 pipelining has not been advertised.

2205 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
2206 was a macro that became an assignment, so it seemed to work. This has

PH
2264 the response to the final '.' that terminates a message, but only in the
2265 case where the client has not sent further data following the '.'
2266 (unfortunately, this is allowed). However, in many cases there won't be
2267 any further data because there won't be any more messages to send. A call
2268 to select() can be used: if it shows that the input is "ready", there is
2269 either input waiting, or the socket has been closed. An attempt to read
2270 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2271 would have sent an OK response which the client would never have see.

2282PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2283 fixed by 4.65/MH/01 (is this a record?) are fixed:
2284
2285 (i) An empty string was always treated as zero by the numeric comparison
2286 operators. This behaviour has been restored.
2287
2288 (ii) It is documented that the numeric comparison operators always treat
2289 their arguments as decimal numbers. This was broken in that numbers
2290 starting with 0 were being interpreted as octal.
2291
2292 While fixing these problems I realized that there was another issue that
2293 hadn't been noticed. Values of message_size_limit (both the global option
2294 and the transport option) were treated as octal if they started with 0.
2295 The documentation was vague. These values are now always treated as
2296 decimal, and I will make that clear in the documentation.

2321TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2322 leftover -K file (the existence of which was triggered by #402).
2323 While we were at it, introduced process PID as part of the -K
2324 filename. This should rule out race conditions when creating
2325 these files.
2326
2327TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
2328 processing considerably. Previous code took too long for large mails,
2329 triggering a timeout which in turn triggers #401.
2330
2331TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
2332 in the DK code in transports.c. sendfile() is not really portable,
2333 hence the _LINUX specificness.

2335TF/01 In the add_headers option to the mail command in an Exim filter,
2336 there was a bug that Exim would claim a syntax error in any
2337 header after the first one which had an odd number of characters
2338 in the field name.

PH
2340PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2341 callout verification, Exim cached a "reject" for the entire domain. This
2342 is correct for most verifications, but it is not correct for a recipient
2343 verification with use_sender or use_postmaster set, because in that case
2344 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2345 case of MAIL FROM:<> rejection from other early rejections (e.g.
2346 rejection of HELO). When verifying a recipient using a non-null MAIL
2347 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2348 Whatever the result of the callout, the value of the domain cache is
2349 left unchanged (for any other kind of callout, getting as far as trying
2350 RCPT means that the domain itself is ok).

PH
2384PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2385 hostname. This is wrong, because it relates to the incoming message (and
2386 probably the interface on which it is arriving) and not to the outgoing
2387 callout (which could be using a different interface). This has been
2388 changed to use the value of the helo_data option from the smtp transport
2389 instead - this is what is used when a message is actually being sent. If
2390 there is no remote transport (possible with a router that sets up host
2391 addresses), $smtp_active_hostname is used.

14aa5a05 2393PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2394 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2395 (a) The code assumed that strncpy() returns a negative number on buffer
2396 overflow, which isn't the case. Replaced with Exim's string_format()
2397 function.
2398 (b) There were several signed/unsigned issues. I just did the minimum
2399 hacking in of casts. There is scope for a larger refactoring.
2400 (c) The code used strcasecmp() which is not a standard C function.
2401 Replaced with Exim's strcmpic() function.
2402 (d) The code set only $1; it now sets $auth1 as well.
2403 (e) A simple test gave the error "authentication client didn't specify
2404 service in request". It would seem that Dovecot has changed its
2405 interface. Fortunately there's a specification; I followed it and
2406 changed what the client sends and it appears to be working now.

2411PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2412 address A is aliased to B and C, where B exists and C does not. Without
2413 -v the output is "A verified" because verification stops after a
2414 successful redirection if more than one address is generated. However,
2415 with -v the child addresses are also verified. Exim was outputting "A
2416 failed to verify" and then showing the successful verification for C,
2417 with its parentage. It now outputs "B failed to verify", showing B's
2418 parentage before showing the successful verification of C.

2420PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
2421 look up a TXT record in a specific list after matching in a combined
2422 list.
2423
322050c2
PH
2424PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2425 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2426 they consult the DNS. I had assumed they would set it the way they
2427 wanted; and indeed my experiments on Linux seem to show that in some
2428 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2429 To be on the safe side, however, I have now made the interface to
2430 host_find_byname() similar to host_find_bydns(), with an argument
2431 containing the DNS resolver options. The host_find_byname() function now
2432 sets these options at its start, just as host_find_bydns() does. The smtp
2433 transport options dns_qualify_single and dns_search_parents are passed to
2434 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2435 of host_find_byname() use the default settings of RES_DEFNAMES
2436 (qualify_single) but not RES_DNSRCH (search_parents).
2437

PH
2438PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2439 spool_read_header() do less string testing, by means of a preliminary
2440 switch on the second character of optional "-foo" lines. (This is
2441 overdue, caused by the large number of possibilities that now exist.
2442 Originally there were few.) While I was there, I also converted the
2443 str(n)cmp tests so they don't re-test the leading "-" and the first
2444 character, in the hope this might squeeze out yet more improvement.
2445

PH
2446PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2447 flag allowing group syntax was set by the header_syntax check but not
2448 turned off, possible causing trouble later; (2) The flag was not being
2449 set at all for the header_verify test, causing "group"-style headers to
2450 be rejected. I have now set it in this case, and also caused header_
2451 verify to ignore an empty address taken from a group. While doing this, I
2452 came across some other cases where the code for allowing group syntax
2453 while scanning a header line wasn't quite right (mostly, not resetting
2454 the flag correctly in the right place). These bugs could have caused
2455 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
2457PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2458 with the "reply" argument non-NULL. The code, however (which originally
2459 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2460 but it didn't always do it. This confused somebody who was copying the
2461 code for some other use. I have removed all the tests.
2462
411ef850
PH
2463PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2464 feature that was used to support insecure browsers during the U.S. crypto
2465 embargo. It requires special client support, and Exim is probably the
2466 only MTA that supported it -- and would never use it because real RSA is
2467 always available. This code has been removed, because it had the bad
2468 effect of slowing Exim down by computing (never used) parameters for the
2469 RSA_EXPORT functionality.
2470
7befa435
PH
2471PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2472 authenticator to fail if there's a tab character in the incoming data
2473 (there should never be unless someone is messing about, as it's supposed
2474 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2475 if the connection is using TLS or if the remote IP is the same as the
2476 local IP, and the "valid-client-cert option" if a client certificate has
2477 been verified.
2478
48da4259 2479PH/22 As suggested by Dennis Davis, added a server_condition option to *all*

PH
2508
2509PH/30 Exim was sometimes attempting to deliver messages that had suffered
2510 address errors (4xx response to RCPT) over the same connection as other
2511 messages routed to the same hosts. Such deliveries are always "forced",
2512 so retry times are not inspected. This resulted in far too many retries
2513 for the affected addresses. The effect occurred only when there were more
2514 hosts than the hosts_max_try setting in the smtp transport when it had
2515 the 4xx errors. Those hosts that it had tried were not added to the list
2516 of hosts for which the message was waiting, so if all were tried, there
2517 was no problem. Two fixes have been applied:
2518
2519 (i) If there are any address or message errors in an SMTP delivery, none
2520 of the hosts (tried or untried) are now added to the list of hosts
2521 for which the message is waiting, so the message should not be a
2522 candidate for sending over the same connection that was used for a
2523 successful delivery of some other message. This seems entirely
2524 reasonable: after all the message is NOT "waiting for some host".
2525 This is so "obvious" that I'm not sure why it wasn't done
2526 previously. Hope I haven't missed anything, but it can't do any
2527 harm, as the worst effect is to miss an optimization.
2528
2529 (ii) If, despite (i), such a delivery is accidentally attempted, the
2530 routing retry time is respected, so at least it doesn't keep
2531 hammering the server.

2546PH/35 The error "getsockname() failed: connection reset by peer" was being
2547 written to the panic log as well as the main log, but it isn't really
2548 panic-worthy as it just means the connection died rather early on. I have
2549 removed the panic log writing for the ECONNRESET error when getsockname()
2550 fails.
2551
48c7f9e2
PH
2552PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2553 runs only) independently of the message's sender address. This meant
2554 that, if the 4xx error was in fact related to the sender, a different
2555 message to the same recipient with a different sender could confuse
4c04137d 2556 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2557 server, but other circumstances could also provoke similar problems.
2558 I have changed the default so that the retry time for these errors is now
2559 based a combination of the sender and recipient addresses. This change
2560 can be overridden by setting address_retry_include_sender=false in the
2561 smtp transport.

2832 tcp-wrappers gives "deny", whereas what one would like would be some
2833 kind of temporary error. A kludge has been added to help with this.
2834 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2835 554 error is used if errno is still zero or contains ENOENT (which occurs
2836 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2876 code found IPv4 interfaces correctly, but gave incorrect values for the
2877 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2878 that it would not match correctly against @[] and not recognize the IPv6
2879 addresses as local.

2922 autoreply, Exim could try to deliver to a non-existent relative file

2957 additional section of a DNS packet that returns MX or SRV records.
2958 Instead, it always explicitly searches for A/AAAA records. This avoids
2959 major problems that occur when a DNS server includes only records of one
2960 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2961 fixed another bug: if SRV records were looked up and the corresponding
2962 address records were *not* found in the additional section, the port
2963 values from the SRV records were lost.

2965PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2973PH/19 When calculating a retry time, Exim used to measure the "time since
2974 failure" by looking at the "first failed" field in the retry record. Now
2975 it does not use this if it is later than than the arrival time of the
2976 message. Instead it uses the arrival time. This makes for better
2977 behaviour in cases where some deliveries succeed, thus re-setting the
2978 "first failed" field. An example is a quota failure for a huge message
2979 when small messages continue to be delivered. Without this change, the
2980 "time since failure" will always be short, possible causing more frequent
2981 delivery attempts for the huge message than are intended.

3080 the files. Exim runs with umask(0) because the rest of the code creates
3081 files with open(), and sets the required mode explicitly. Thus, these
3082 files were ending up world-writeable. This was not a big issue, because,
3083 being within the spool directory, they were not world-accessible. I have
3084 created a function called modefopen, which takes an additional mode
3085 argument. It sets umask(777), creates the file, chmods it to the required
3086 mode, then resets the umask. All the relevant calls to fopen() in the
3087 content scanning code have been changed to use this function.

3095PH/45 When the plaintext authenticator is running as a client, the server's
3096 challenges are checked to ensure they are valid base64 strings. By
3097 default, the authentication attempt is cancelled if an invalid string is
3098 received. Setting client_ignore_invalid_base64 true ignores these errors.
3099 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
3100 they are received. Thus, the responses can be made to depend on the
3101 challenges. If an invalid string is ignored, an empty string is placed in
3102 the variable.

3113PH/50 When an Exim quota was set without a file count quota, and mailbox_size
3114 was also set, the appendfile transport was unnecessarily scanning a
3115 directory of message files (e.g. for maildir delivery) to find the count
3116 of files (along with the size), even though it did not need this
3117 information. It now does the scan only if it needs to find either the
3118 size of the count of files.

3122PH/52 Two bugs concerned with error handling when the smtp transport is
3123 used in LMTP mode:
3124
3125 (i) Exim was not creating retry information for temporary errors given
3126 for individual recipients after the DATA command when the smtp transport
3127 was used in LMTP mode. This meant that they could be retried too
3128 frequently, and not timed out correctly.
3129
3130 (ii) Exim was setting the flag that allows error details to be returned
3131 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3132 recipients that were returned after the DATA command.
3133
3134PH/53 This is related to PH/52, but is more general: for any failing address,
3135 when detailed error information was permitted to be returned to the
3136 sender, but the error was temporary, then after the final timeout, only
3137 "retry timeout exceeded" was returned. Now it returns the full error as
3138 well as "retry timeout exceeded".

3194PH/68 The bounce_return_message and bounce_return_body options were not being

3196 In particular, this applied to messages rejected by the ACL. This bug has
3197 been fixed. However, if bounce_return_message is true and bounce_return_
3198 body is false, the headers that are returned for a non-SMTP message
3199 include only those that have been read before the error was detected.

3208PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3209 function verify_get_ident() calls ip_connect() to connect a socket, but
3210 if the "connect()" function timed out, ip_connect() used to close the
3211 socket. However, verify_get_ident() also closes the socket later, and in
3212 between Exim writes to the log, which may get opened at this point. When
3213 the socket was closed in ip_connect(), the log could get the same file
3214 descriptor number as the socket. This naturally causes chaos. The fix is
3215 not to close the socket in ip_connect(); the socket should be closed by
3216 the function that creates it. There was only one place in the code where
3217 this was missing, in the iplookup router, which I don't think anybody now
3218 uses, but I've fixed it anyway.

3237PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3238
3239 (1) Generate an error if the third argument for the ${prvs expansion is
3240 not a single digit.
3241
3242 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3243 string.
3244
3245 (3) Reset the variables that are obtained from the first argument of
3246 ${prvscheck and used in the second argument before leaving the code,
3247 because their memory is reclaimed, so using them afterwards may do
3248 silly things.
3249
3250 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3251 one (it's much easier than Tom thought :-).
3252
3253 (5) Because of (4), we can now allow for the use of $prvscheck_result
3254 inside the third argument.

3275 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3276 not being looked up in the rDNS to get a host name, Exim was showing the
3277 IP address twice in Received: lines, even though the IP addresses were
3278 identical. For example:
3279
3280 Received: from [1.2.3.4] (helo=[1.2.3.4])
