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.

16PP/01 Allow PKG_CONFIG_PATH to be set in Local/Makefile and use it correctly
17 during configuration. Wildcards are allowed and expanded.

4c04137d 27 than -2003 did; needs libidn2 in addition to libidn.

37JH/04 Bug 2004: fix CHUNKING in non-PIPELINEING mode. Chunk data following
38 close after a BDAT command line could be taken as a following command,
39 giving a synch failure. Fix by only checking for synch immediately
40 before acknowledging the chunk.

46JH/05 Have the EHLO response advertise VRFY, if there is a vrfy ACL defined.
47 Previously we did not; the RFC seems ambiguous and VRFY is not listed
48 by IANA as a service extension. However, John Klensin suggests that we
49 should.

51JH/06 Bug 2017: Fix DKIM verification in -bh test mode. The data feed into

52 the dkim code may be unix-mode line endings rather than smtp wire-format
53 CRLF, so prepend a CR to any bare LF.

bd8fbe36 55JH/07 Rationalise the coding for callout smtp conversations and transport ones.
902fbd69
JH
56 As a side-benfit, callouts can now use PIPELINING hence fewer round-trips.
57

JH
58JH/08 Bug 2016: Fix DKIM verification vs. CHUNKING. Any BDAT commands after
59 the first were themselves being wrongly included in the feed into dkim
60 processing; with most chunk sizes in use this resulted in an incorrect
61 body hash calculated value.
62

JH
63JH/09 Bug 2014: permit inclusion of a DKIM-Signature header in a received
64 DKIM signature block, for verification. Although advised against by
65 standards it is specifically not ruled illegal.

JH
67JH/10 Bug 2025: Fix reception of (quoted) local-parts with embedded spaces.
68
69JH/11 Bug 2029: Fix crash in DKIM verification when a message signature block is
70 missing a body hash (the bh= tag).
71
72JH/12 Bug 2018: Re-order Proxy Protocol startup versus TLS-on-connect startup.
73 It seems that HAProxy sends the Proxy Protocol information in clear and
74 only then does a TLS startup, so do the same.
75
76JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
77 TCP connections (such as for Spamd) unless the daemon successfully set
78 Fast Open mode on its listening sockets. This fixes breakage seen on
79 too-old kernels or those not configured for Fast Open, at the cost of
80 requiring both directions being enabled for TFO, and TFO never being used
81 by non-daemon-related Exim processes.
82
83JH/14 Bug 2000: Reject messages recieved with CHUNKING but with malformed line
84 endings, at least on the first header line. Try to canonify any that get
85 past that check, despite the cost.
86

JH
87JH/15 Angle-bracket nesting (an error inserted by broken sendmails) levels are
88 now limited to an arbitrary five deep, while parsing addresses with the
89 strip_excess_angle_brackets option enabled.

98
90341c71
JH
99JH/16 Drop variables when they go out of scope. Memory management drops a whole
100 region in one operation, for speed, and this leaves assigned pointers
101 dangling. Add checks run only under the testsuite which checks all
102 variables at a store-reset and panics on a dangling pointer; add code
103 explicitly nulling out all the variables discovered. Fixes one known
104 bug: a transport crash, where a dangling pointer for $sending_ip_address
105 originally assigned in a verify callout, is re-used.

131JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
132 supports it and a size is available (ie. the sending peer gave us one).
8d042305 133

JH
134JH/02 The obsolete acl condition "demime" is removed (finally, after ten
135 years of being deprecated). The replacements are the ACLs
136 acl_smtp_mime and acl_not_smtp_mime.
137
4b0fe319
JH
138JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
139 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
140 or even an in-clear connection were permitted. Now, if the host lookup
141 was dnssec and dane was requested then the host is only used if the
142 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
143 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
144 if one fails this test.
145 This means that a poorly-configured remote DNS will make it incommunicado;
146 but it protects against a DNS-interception attack on it.

JH
168JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
169 a cutthrough deliver is pending, as we always want to make a connection.
170 This also avoids re-routing the message when later placing the cutthrough
171 connection after a verify cache hit.
172 Do not update it with the verify result either.
173
174JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
175 when routing results in more than one destination address.
176
ae8386f0
JH
177JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
178 signing (which inhibits the cutthrough capability). Previously only
179 the presence of an option was tested; now an expansion evaluating as
180 empty is permissible (obviously it should depend only on data available
181 when the cutthrough connection is made).

291 open indefinitely after a "too many connections" event, including to a
292 deleted file after a log rotate. Leave the per net connection logging

362 in transport context, after the attempt, and per-recipient. The latter type
363 is per host attempted. The event data is the error message, and the errno
364 information encodes the lookup type (A vs. MX) used for the (first) host,
4c04137d 365 and the trailing two digits of the smtp 4xx response.

960TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
961
962 When a queue runner is handling a message, Exim first routes the
963 recipient addresses, during which it prunes them based on the retry
964 hints database. After that it attempts to deliver the message to
965 any remaining recipients. It then updates the hints database using
966 the retry rules.
967
968 So if a recipient address works intermittently, it can get repeatedly
969 deferred at routing time. The retry hints record remains fresh so the
970 address never reaches the final cutoff time.
971
972 This is a fairly common occurrence when a user is bumping up against
973 their storage quota. Exim had some logic in its local delivery code
974 to deal with this. However it did not apply to per-recipient defers
975 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
976
1ddeb334
TF
977 This change adds a proper retry rule check during routing so that the
978 final cutoff time is checked against the message's age. We only do
979 this check if there is an address retry record and there is not a
980 domain retry record; this implies that previous attempts to handle
981 the address had the retry_use_local_parts option turned on. We use
982 this as an approximation for the destination being like a local
983 delivery, as in LMTP.
67bd1ab3
TF
984
985 I suspect this new check makes the old local delivery cutoff check
986 redundant, but I have not verified this so I left the code in place.

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

1021 Server implementation by Todd Lyons, client by JH.
1022 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
1023 config variable "prdr_enable" controls whether the server
1024 advertises the facility. If the client requests PRDR a new
1025 acl_data_smtp_prdr ACL is called once for each recipient, after
1026 the body content is received and before the acl_smtp_data ACL.
4c04137d 1027 The client is controlled by both of: a hosts_try_prdr option

1028 on the smtp transport, and the server advertisement.

1308TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1309 lock up or crash if it happened to be inside a call to libc when it
1310 got a SIGUSR1 from exiwhat.
1311
1312 The SIGUSR1 handler appends the current process status to the process
1313 log which is later printed by exiwhat. It used to use the general
1314 purpose logging code to do this, but several functions it calls are
1315 not safe for signals.
1316
1317 The new output code in the SIGUSR1 handler is specific to the process
1318 log, and simple enough that it's easy to inspect for signal safety.
1319 Removing some special cases also simplifies the general logging code.
1320 Removing the spurious timestamps from the process log simplifies
1321 exiwhat.
1322
c99ce5c9
TF
1323TF/04 Improved ratelimit ACL condition.
1324
1325 The /noupdate option has been deprecated in favour of /readonly which
1326 has clearer semantics. The /leaky, /strict, and /readonly update modes
1327 are mutually exclusive. The update mode is no longer included in the
1328 database key; it just determines when the database is updated. (This
4c04137d 1329 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1330
1331 Exim now checks that the per_* options are used with an update mode that
1332 makes sense for the current ACL. For example, when Exim is processing a
1333 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1334 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1335 must specify per_mail/readonly. If you omit the update mode it defaults to
1336 /leaky where that makes sense (as before) or /readonly where required.
1337
1338 The /noupdate option is now undocumented but still supported for
1339 backwards compatibility. It is equivalent to /readonly except that in
1340 ACLs where /readonly is required you may specify /leaky/noupdate or
1341 /strict/noupdate which are treated the same as /readonly.
1342
1343 A useful new feature is the /count= option. This is a generalization
1344 of the per_byte option, so that you can measure the throughput of other
1345 aggregate values. For example, the per_byte option is now equivalent
1346 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1347
1348 The per_rcpt option has been generalized using the /count= mechanism
1349 (though it's more complicated than the per_byte equivalence). When it is
1350 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1351 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1352 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1353 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1354 Note that using per_rcpt with a non-readonly update mode in more than
1355 one ACL will cause the recipients to be double-counted. (The per_mail
1356 and per_byte options don't have this problem.)
1357
1358 The handling of very low rates has changed slightly. If the computed rate
1359 is less than the event's count (usually one) then this event is the first
1360 after a long gap. In this case the rate is set to the same as this event's
1361 count, so that the first message of a spam run is counted properly.
1362
1363 The major new feature is a mechanism for counting the rate of unique
1364 events. The new per_addr option counts the number of different
1365 recipients that someone has sent messages to in the last time period. It
1366 behaves like per_rcpt if all the recipient addresses are different, but
1367 duplicate recipient addresses do not increase the measured rate. Like
1368 the /count= option this is a general mechanism, so the per_addr option
1369 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1370 example, measure the rate that a client uses different sender addresses
1371 with the options per_mail/unique=$sender_address. There are further
1372 details in the main documentation.

1944PH/01 Another patch from the Sieve maintainer.
1945
6a3bceb1
PH
1946PH/02 When an IPv6 address is converted to a string for single-key lookup
1947 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1948 dots are used instead of colons so that keys in lsearch files need not
1949 contain colons. This was done some time before quoting was made available
1950 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1951 (notated using the quote facility) so as to distinguish them from IPv4
1952 keys. This meant that lookups for IP addresses in host lists did not work
1953 for iplsearch lookups.
1954
1955 This has been fixed by arranging for IPv6 addresses to be expressed with
1956 colons if the lookup type is iplsearch. This is not incompatible, because
1957 previously such lookups could never work.
1958
4c04137d 1959 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
1960 ordinary lsearch keys. However, making the change in all cases is

1966MH/01 The "spam" ACL condition code contained a sscanf() call with a %s

1968 a rogue spamd server to cause a buffer overflow. While nobody in their
1969 right mind would setup Exim to query an untrusted spamd server, an
1970 attacker that gains access to a server running spamd could potentially
1971 exploit this vulnerability to run arbitrary code as the Exim user.

1976MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for

1978 symlink pointed to a non-existing file or a file in a directory that
1979 Exim lacked permissions to read, a lookup for a key matching that

2167 some time before the response is written. In this time, more input might
2168 arrive, invalidly. So now there are extra checks after an ACL has run for
2169 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2170 pipelining has not been advertised.

2185 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()

2244 the response to the final '.' that terminates a message, but only in the
2245 case where the client has not sent further data following the '.'
2246 (unfortunately, this is allowed). However, in many cases there won't be
2247 any further data because there won't be any more messages to send. A call
2248 to select() can be used: if it shows that the input is "ready", there is
2249 either input waiting, or the socket has been closed. An attempt to read
2250 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2251 would have sent an OK response which the client would never have see.

2263 fixed by 4.65/MH/01 (is this a record?) are fixed:
2264
2265 (i) An empty string was always treated as zero by the numeric comparison
2266 operators. This behaviour has been restored.
2267
2268 (ii) It is documented that the numeric comparison operators always treat
2269 their arguments as decimal numbers. This was broken in that numbers
2270 starting with 0 were being interpreted as octal.
2271
2272 While fixing these problems I realized that there was another issue that
2273 hadn't been noticed. Values of message_size_limit (both the global option
2274 and the transport option) were treated as octal if they started with 0.
2275 The documentation was vague. These values are now always treated as
2276 decimal, and I will make that clear in the documentation.

PH
2320PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2321 callout verification, Exim cached a "reject" for the entire domain. This
2322 is correct for most verifications, but it is not correct for a recipient
2323 verification with use_sender or use_postmaster set, because in that case
2324 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2325 case of MAIL FROM:<> rejection from other early rejections (e.g.
2326 rejection of HELO). When verifying a recipient using a non-null MAIL
2327 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2328 Whatever the result of the callout, the value of the domain cache is
2329 left unchanged (for any other kind of callout, getting as far as trying
2330 RCPT means that the domain itself is ok).

2364PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2365 hostname. This is wrong, because it relates to the incoming message (and
2366 probably the interface on which it is arriving) and not to the outgoing
2367 callout (which could be using a different interface). This has been
2368 changed to use the value of the helo_data option from the smtp transport
2369 instead - this is what is used when a message is actually being sent. If
2370 there is no remote transport (possible with a router that sets up host
2371 addresses), $smtp_active_hostname is used.

7befa435 2374 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2375 (a) The code assumed that strncpy() returns a negative number on buffer
2376 overflow, which isn't the case. Replaced with Exim's string_format()
2377 function.
2378 (b) There were several signed/unsigned issues. I just did the minimum
2379 hacking in of casts. There is scope for a larger refactoring.
2380 (c) The code used strcasecmp() which is not a standard C function.
2381 Replaced with Exim's strcmpic() function.
2382 (d) The code set only $1; it now sets $auth1 as well.
2383 (e) A simple test gave the error "authentication client didn't specify
2384 service in request". It would seem that Dovecot has changed its
2385 interface. Fortunately there's a specification; I followed it and
2386 changed what the client sends and it appears to be working now.

2391PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2392 address A is aliased to B and C, where B exists and C does not. Without
2393 -v the output is "A verified" because verification stops after a
2394 successful redirection if more than one address is generated. However,
2395 with -v the child addresses are also verified. Exim was outputting "A
2396 failed to verify" and then showing the successful verification for C,
2397 with its parentage. It now outputs "B failed to verify", showing B's
2398 parentage before showing the successful verification of C.

2403
322050c2
PH
2404PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2405 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2406 they consult the DNS. I had assumed they would set it the way they
2407 wanted; and indeed my experiments on Linux seem to show that in some
2408 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2409 To be on the safe side, however, I have now made the interface to
2410 host_find_byname() similar to host_find_bydns(), with an argument
2411 containing the DNS resolver options. The host_find_byname() function now
2412 sets these options at its start, just as host_find_bydns() does. The smtp
2413 transport options dns_qualify_single and dns_search_parents are passed to
2414 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2415 of host_find_byname() use the default settings of RES_DEFNAMES
2416 (qualify_single) but not RES_DNSRCH (search_parents).

PH
2418PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2419 spool_read_header() do less string testing, by means of a preliminary
2420 switch on the second character of optional "-foo" lines. (This is
2421 overdue, caused by the large number of possibilities that now exist.
2422 Originally there were few.) While I was there, I also converted the
2423 str(n)cmp tests so they don't re-test the leading "-" and the first
2424 character, in the hope this might squeeze out yet more improvement.

PH
2426PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2427 flag allowing group syntax was set by the header_syntax check but not
2428 turned off, possible causing trouble later; (2) The flag was not being
2429 set at all for the header_verify test, causing "group"-style headers to
2430 be rejected. I have now set it in this case, and also caused header_
2431 verify to ignore an empty address taken from a group. While doing this, I
2432 came across some other cases where the code for allowing group syntax
2433 while scanning a header line wasn't quite right (mostly, not resetting
2434 the flag correctly in the right place). These bugs could have caused
2435 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
2437PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2438 with the "reply" argument non-NULL. The code, however (which originally
2439 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2440 but it didn't always do it. This confused somebody who was copying the
2441 code for some other use. I have removed all the tests.

PH
2443PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2444 feature that was used to support insecure browsers during the U.S. crypto
2445 embargo. It requires special client support, and Exim is probably the
2446 only MTA that supported it -- and would never use it because real RSA is
2447 always available. This code has been removed, because it had the bad
2448 effect of slowing Exim down by computing (never used) parameters for the
2449 RSA_EXPORT functionality.

PH
2451PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2452 authenticator to fail if there's a tab character in the incoming data
2453 (there should never be unless someone is messing about, as it's supposed
2454 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2455 if the connection is using TLS or if the remote IP is the same as the
2456 local IP, and the "valid-client-cert option" if a client certificate has
2457 been verified.

2488
2489PH/30 Exim was sometimes attempting to deliver messages that had suffered
2490 address errors (4xx response to RCPT) over the same connection as other
2491 messages routed to the same hosts. Such deliveries are always "forced",
2492 so retry times are not inspected. This resulted in far too many retries
2493 for the affected addresses. The effect occurred only when there were more
2494 hosts than the hosts_max_try setting in the smtp transport when it had
2495 the 4xx errors. Those hosts that it had tried were not added to the list
2496 of hosts for which the message was waiting, so if all were tried, there
2497 was no problem. Two fixes have been applied:
2498
2499 (i) If there are any address or message errors in an SMTP delivery, none
2500 of the hosts (tried or untried) are now added to the list of hosts
2501 for which the message is waiting, so the message should not be a
2502 candidate for sending over the same connection that was used for a
2503 successful delivery of some other message. This seems entirely
2504 reasonable: after all the message is NOT "waiting for some host".
2505 This is so "obvious" that I'm not sure why it wasn't done
2506 previously. Hope I haven't missed anything, but it can't do any
2507 harm, as the worst effect is to miss an optimization.
2508
2509 (ii) If, despite (i), such a delivery is accidentally attempted, the
2510 routing retry time is respected, so at least it doesn't keep
2511 hammering the server.

2530 fails.

48c7f9e2
PH
2532PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2533 runs only) independently of the message's sender address. This meant
2534 that, if the 4xx error was in fact related to the sender, a different
2535 message to the same recipient with a different sender could confuse
4c04137d 2536 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2537 server, but other circumstances could also provoke similar problems.
2538 I have changed the default so that the retry time for these errors is now
2539 based a combination of the sender and recipient addresses. This change
2540 can be overridden by setting address_retry_include_sender=false in the
2541 smtp transport.

2809PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
2810 "Deny" causes Exim to reject the incoming connection with a 554 error.
2811 Unfortunately, if there is a major crisis, such as a disk failure,
2812 tcp-wrappers gives "deny", whereas what one would like would be some
2813 kind of temporary error. A kludge has been added to help with this.
2814 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2815 554 error is used if errno is still zero or contains ENOENT (which occurs
2816 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2817 451 error is used.

2842 used only to exclude .Trash (or whatever) when the size of the mailbox

2851-----------------

2853PH/01 The code for finding all the local interface addresses on a FreeBSD
2854 system running IPv6 was broken. This may well have applied to all BSD
2855 systems, as well as to others that have similar system calls. The broken
2856 code found IPv4 interfaces correctly, but gave incorrect values for the
2857 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2858 that it would not match correctly against @[] and not recognize the IPv6
2859 addresses as local.

2900 syntactically invalid From: or Reply-to: line, and a filter used this to
2901 generate an autoreply, and therefore failed to obtain an address for the
2902 autoreply, Exim could try to deliver to a non-existent relative file
2903 name, causing unrelated and misleading errors. What now happens is that
2904 it logs this as a hard delivery error, but does not attempt to create a

2936PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2937 additional section of a DNS packet that returns MX or SRV records.
2938 Instead, it always explicitly searches for A/AAAA records. This avoids
2939 major problems that occur when a DNS server includes only records of one
2940 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2941 fixed another bug: if SRV records were looked up and the corresponding
2942 address records were *not* found in the additional section, the port
2943 values from the SRV records were lost.

PH
2945PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

2952
727071f8
PH
2953PH/19 When calculating a retry time, Exim used to measure the "time since
2954 failure" by looking at the "first failed" field in the retry record. Now
2955 it does not use this if it is later than than the arrival time of the
2956 message. Instead it uses the arrival time. This makes for better
2957 behaviour in cases where some deliveries succeed, thus re-setting the
2958 "first failed" field. An example is a quota failure for a huge message
2959 when small messages continue to be delivered. Without this change, the
2960 "time since failure" will always be short, possible causing more frequent
2961 delivery attempts for the huge message than are intended.

3058PH/42 The content-scanning code uses fopen() to create files in which to put

3061 files with open(), and sets the required mode explicitly. Thus, these
3062 files were ending up world-writeable. This was not a big issue, because,
3063 being within the spool directory, they were not world-accessible. I have
3064 created a function called modefopen, which takes an additional mode
3065 argument. It sets umask(777), creates the file, chmods it to the required
3066 mode, then resets the umask. All the relevant calls to fopen() in the

3093PH/50 When an Exim quota was set without a file count quota, and mailbox_size
3094 was also set, the appendfile transport was unnecessarily scanning a
3095 directory of message files (e.g. for maildir delivery) to find the count
3096 of files (along with the size), even though it did not need this
3097 information. It now does the scan only if it needs to find either the
3098 size of the count of files.

3102PH/52 Two bugs concerned with error handling when the smtp transport is
3103 used in LMTP mode:
3104
3105 (i) Exim was not creating retry information for temporary errors given
3106 for individual recipients after the DATA command when the smtp transport
3107 was used in LMTP mode. This meant that they could be retried too
3108 frequently, and not timed out correctly.
3109
3110 (ii) Exim was setting the flag that allows error details to be returned
3111 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3112 recipients that were returned after the DATA command.
3113
3114PH/53 This is related to PH/52, but is more general: for any failing address,
3115 when detailed error information was permitted to be returned to the
3116 sender, but the error was temporary, then after the final timeout, only
3117 "retry timeout exceeded" was returned. Now it returns the full error as
3118 well as "retry timeout exceeded".

3156PH/62 When verifying, if an address was redirected to one new address, so that
3157 verification continued, and the new address failed or deferred after
3158 having set something in $address_data, the value of $address_data was not
3159 passed back to the ACL. This was different to the case when no
3160 redirection occurred. The value is now passed back in both cases.

3174PH/68 The bounce_return_message and bounce_return_body options were not being
3175 honoured for bounces generated during the reception of non-SMTP messages.
3176 In particular, this applied to messages rejected by the ACL. This bug has
3177 been fixed. However, if bounce_return_message is true and bounce_return_
3178 body is false, the headers that are returned for a non-SMTP message
3179 include only those that have been read before the error was detected.
3180 (In the case of an ACL rejection, they have all been read.)

3182PH/69 The HTML version of the specification is now built in a directory called

PH
3188PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3189 function verify_get_ident() calls ip_connect() to connect a socket, but
3190 if the "connect()" function timed out, ip_connect() used to close the
3191 socket. However, verify_get_ident() also closes the socket later, and in
3192 between Exim writes to the log, which may get opened at this point. When
3193 the socket was closed in ip_connect(), the log could get the same file
3194 descriptor number as the socket. This naturally causes chaos. The fix is
3195 not to close the socket in ip_connect(); the socket should be closed by
3196 the function that creates it. There was only one place in the code where
3197 this was missing, in the iplookup router, which I don't think anybody now
3198 uses, but I've fixed it anyway.

3213 (2) Add control=submission to the relay_from_hosts and authenticated
3214 clients checks, on the grounds that messages accepted by these
3215 statements are most likely to be submissions.

PH
3217PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3218
3219 (1) Generate an error if the third argument for the ${prvs expansion is
3220 not a single digit.
3221
3222 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3223 string.
3224
3225 (3) Reset the variables that are obtained from the first argument of
3226 ${prvscheck and used in the second argument before leaving the code,
3227 because their memory is reclaimed, so using them afterwards may do
3228 silly things.
3229
3230 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3231 one (it's much easier than Tom thought :-).
3232
3233 (5) Because of (4), we can now allow for the use of $prvscheck_result
3234 inside the third argument.

PH
3243PH/05 When a filter generated an autoreply, the entire To: header line was
3244 quoted in the delivery log line, like this:
3245
3246 => >A.N.Other <ano@some.domain> <original@ddress> ...
3247
3248 This has been changed so that it extracts the operative address. There
3249 may be more than one such address. If so, they are comma-separated, like
3250 this:
3251
3252 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
3254PH/06 When a client host used a correct literal IP address in a HELO or EHLO
3255 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3256 not being looked up in the rDNS to get a host name, Exim was showing the
3257 IP address twice in Received: lines, even though the IP addresses were
3258 identical. For example:
3259
3260 Received: from [1.2.3.4] (helo=[1.2.3.4])
3261
3262 However, if the real host name was known, it was omitting the HELO data
3263 if it matched the actual IP address. This has been tidied up so that it
3264 doesn't show the same IP address twice.

PH
3266PH/07 When both +timestamp and +memory debugging was on, the value given by
3267 $tod_xxx expansions could be wrong, because the tod_stamp() function was
3268 called by the debug printing, thereby overwriting the timestamp buffer.
3269 Debugging no longer uses the tod_stamp() function when +timestamp is set.

3271PH/08 When the original message was included in an autoreply transport, it

3274 message.
