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.

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.

42PP/02 GitHub PR 52: many spelling fixes, which include fixing parsing of

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.

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.

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
b6040544
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.

135JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
136 supports it and a size is available (ie. the sending peer gave us one).

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

153 non-noisy when a race steals the message being considered.

98c82a3d
JH
172JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
173 a cutthrough deliver is pending, as we always want to make a connection.
174 This also avoids re-routing the message when later placing the cutthrough
175 connection after a verify cache hit.
176 Do not update it with the verify result either.
177
178JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
179 when routing results in more than one destination address.
180
ae8386f0
JH
181JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
182 signing (which inhibits the cutthrough capability). Previously only
183 the presence of an option was tested; now an expansion evaluating as
184 empty is permissible (obviously it should depend only on data available
185 when the cutthrough connection is made).

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

367 is per host attempted. The event data is the error message, and the errno
368 information encodes the lookup type (A vs. MX) used for the (first) host,
4c04137d 369 and the trailing two digits of the smtp 4xx response.

964TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
965
966 When a queue runner is handling a message, Exim first routes the
967 recipient addresses, during which it prunes them based on the retry
968 hints database. After that it attempts to deliver the message to
969 any remaining recipients. It then updates the hints database using
970 the retry rules.
971
972 So if a recipient address works intermittently, it can get repeatedly
973 deferred at routing time. The retry hints record remains fresh so the
974 address never reaches the final cutoff time.
975
976 This is a fairly common occurrence when a user is bumping up against
977 their storage quota. Exim had some logic in its local delivery code
978 to deal with this. However it did not apply to per-recipient defers
979 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
980
1ddeb334
TF
981 This change adds a proper retry rule check during routing so that the
982 final cutoff time is checked against the message's age. We only do
983 this check if there is an address retry record and there is not a
984 domain retry record; this implies that previous attempts to handle
985 the address had the retry_use_local_parts option turned on. We use
986 this as an approximation for the destination being like a local
987 delivery, as in LMTP.
67bd1ab3
TF
988
989 I suspect this new check makes the old local delivery cutoff check
990 redundant, but I have not verified this so I left the code in place.

999 the header to contain my full name, whereas it should have added
1000 a Resent-Sender: header. It erroneously treats any prefix of the
1001 username as equal to the username.

1025 Server implementation by Todd Lyons, client by JH.
1026 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
1027 config variable "prdr_enable" controls whether the server
1028 advertises the facility. If the client requests PRDR a new
1029 acl_data_smtp_prdr ACL is called once for each recipient, after
1030 the body content is received and before the acl_smtp_data ACL.
4c04137d 1031 The client is controlled by both of: a hosts_try_prdr option

1032 on the smtp transport, and the server advertisement.

1312TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1313 lock up or crash if it happened to be inside a call to libc when it
1314 got a SIGUSR1 from exiwhat.
1315
1316 The SIGUSR1 handler appends the current process status to the process
1317 log which is later printed by exiwhat. It used to use the general
1318 purpose logging code to do this, but several functions it calls are
1319 not safe for signals.
1320
1321 The new output code in the SIGUSR1 handler is specific to the process
1322 log, and simple enough that it's easy to inspect for signal safety.
1323 Removing some special cases also simplifies the general logging code.
1324 Removing the spurious timestamps from the process log simplifies
1325 exiwhat.
1326
c99ce5c9
TF
1327TF/04 Improved ratelimit ACL condition.
1328
1329 The /noupdate option has been deprecated in favour of /readonly which
1330 has clearer semantics. The /leaky, /strict, and /readonly update modes
1331 are mutually exclusive. The update mode is no longer included in the
1332 database key; it just determines when the database is updated. (This
4c04137d 1333 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1334
1335 Exim now checks that the per_* options are used with an update mode that
1336 makes sense for the current ACL. For example, when Exim is processing a
1337 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1338 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1339 must specify per_mail/readonly. If you omit the update mode it defaults to
1340 /leaky where that makes sense (as before) or /readonly where required.
1341
1342 The /noupdate option is now undocumented but still supported for
1343 backwards compatibility. It is equivalent to /readonly except that in
1344 ACLs where /readonly is required you may specify /leaky/noupdate or
1345 /strict/noupdate which are treated the same as /readonly.
1346
1347 A useful new feature is the /count= option. This is a generalization
1348 of the per_byte option, so that you can measure the throughput of other
1349 aggregate values. For example, the per_byte option is now equivalent
1350 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1351
1352 The per_rcpt option has been generalized using the /count= mechanism
1353 (though it's more complicated than the per_byte equivalence). When it is
1354 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1355 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1356 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1357 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1358 Note that using per_rcpt with a non-readonly update mode in more than
1359 one ACL will cause the recipients to be double-counted. (The per_mail
1360 and per_byte options don't have this problem.)
1361
1362 The handling of very low rates has changed slightly. If the computed rate
1363 is less than the event's count (usually one) then this event is the first
1364 after a long gap. In this case the rate is set to the same as this event's
1365 count, so that the first message of a spam run is counted properly.
1366
1367 The major new feature is a mechanism for counting the rate of unique
1368 events. The new per_addr option counts the number of different
1369 recipients that someone has sent messages to in the last time period. It
1370 behaves like per_rcpt if all the recipient addresses are different, but
1371 duplicate recipient addresses do not increase the measured rate. Like
1372 the /count= option this is a general mechanism, so the per_addr option
1373 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1374 example, measure the rate that a client uses different sender addresses
1375 with the options per_mail/unique=$sender_address. There are further
1376 details in the main documentation.

PH
1950PH/02 When an IPv6 address is converted to a string for single-key lookup
1951 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1952 dots are used instead of colons so that keys in lsearch files need not
1953 contain colons. This was done some time before quoting was made available
1954 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1955 (notated using the quote facility) so as to distinguish them from IPv4
1956 keys. This meant that lookups for IP addresses in host lists did not work
1957 for iplsearch lookups.
1958
1959 This has been fixed by arranging for IPv6 addresses to be expressed with
1960 colons if the lookup type is iplsearch. This is not incompatible, because
1961 previously such lookups could never work.
1962
4c04137d 1963 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
1964 ordinary lsearch keys. However, making the change in all cases is

1970MH/01 The "spam" ACL condition code contained a sscanf() call with a %s

1972 a rogue spamd server to cause a buffer overflow. While nobody in their
1973 right mind would setup Exim to query an untrusted spamd server, an
1974 attacker that gains access to a server running spamd could potentially
1975 exploit this vulnerability to run arbitrary code as the Exim user.

1980MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for

2171 some time before the response is written. In this time, more input might
2172 arrive, invalidly. So now there are extra checks after an ACL has run for
2173 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2174 pipelining has not been advertised.

2248 the response to the final '.' that terminates a message, but only in the
2249 case where the client has not sent further data following the '.'
2250 (unfortunately, this is allowed). However, in many cases there won't be
2251 any further data because there won't be any more messages to send. A call
2252 to select() can be used: if it shows that the input is "ready", there is
2253 either input waiting, or the socket has been closed. An attempt to read
2254 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2255 would have sent an OK response which the client would never have see.

2267 fixed by 4.65/MH/01 (is this a record?) are fixed:
2268
2269 (i) An empty string was always treated as zero by the numeric comparison
2270 operators. This behaviour has been restored.
2271
2272 (ii) It is documented that the numeric comparison operators always treat
2273 their arguments as decimal numbers. This was broken in that numbers
2274 starting with 0 were being interpreted as octal.
2275
2276 While fixing these problems I realized that there was another issue that
2277 hadn't been noticed. Values of message_size_limit (both the global option
2278 and the transport option) were treated as octal if they started with 0.
2279 The documentation was vague. These values are now always treated as
2280 decimal, and I will make that clear in the documentation.

2319TF/01 In the add_headers option to the mail command in an Exim filter,
2320 there was a bug that Exim would claim a syntax error in any
2321 header after the first one which had an odd number of characters
2322 in the field name.

PH
2324PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2325 callout verification, Exim cached a "reject" for the entire domain. This
2326 is correct for most verifications, but it is not correct for a recipient
2327 verification with use_sender or use_postmaster set, because in that case
2328 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2329 case of MAIL FROM:<> rejection from other early rejections (e.g.
2330 rejection of HELO). When verifying a recipient using a non-null MAIL
2331 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2332 Whatever the result of the callout, the value of the domain cache is
2333 left unchanged (for any other kind of callout, getting as far as trying
2334 RCPT means that the domain itself is ok).

2368PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2369 hostname. This is wrong, because it relates to the incoming message (and
2370 probably the interface on which it is arriving) and not to the outgoing
2371 callout (which could be using a different interface). This has been
2372 changed to use the value of the helo_data option from the smtp transport
2373 instead - this is what is used when a message is actually being sent. If
2374 there is no remote transport (possible with a router that sets up host
2375 addresses), $smtp_active_hostname is used.

14aa5a05 2377PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2378 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2379 (a) The code assumed that strncpy() returns a negative number on buffer
2380 overflow, which isn't the case. Replaced with Exim's string_format()
2381 function.
2382 (b) There were several signed/unsigned issues. I just did the minimum
2383 hacking in of casts. There is scope for a larger refactoring.
2384 (c) The code used strcasecmp() which is not a standard C function.
2385 Replaced with Exim's strcmpic() function.
2386 (d) The code set only $1; it now sets $auth1 as well.
2387 (e) A simple test gave the error "authentication client didn't specify
2388 service in request". It would seem that Dovecot has changed its
2389 interface. Fortunately there's a specification; I followed it and
2390 changed what the client sends and it appears to be working now.

PH
2395PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2396 address A is aliased to B and C, where B exists and C does not. Without
2397 -v the output is "A verified" because verification stops after a
2398 successful redirection if more than one address is generated. However,
2399 with -v the child addresses are also verified. Exim was outputting "A
2400 failed to verify" and then showing the successful verification for C,
2401 with its parentage. It now outputs "B failed to verify", showing B's
2402 parentage before showing the successful verification of C.

2404PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
2405 look up a TXT record in a specific list after matching in a combined

2407
322050c2
PH
2408PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2409 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2410 they consult the DNS. I had assumed they would set it the way they
2411 wanted; and indeed my experiments on Linux seem to show that in some
2412 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2413 To be on the safe side, however, I have now made the interface to
2414 host_find_byname() similar to host_find_bydns(), with an argument
2415 containing the DNS resolver options. The host_find_byname() function now
2416 sets these options at its start, just as host_find_bydns() does. The smtp
2417 transport options dns_qualify_single and dns_search_parents are passed to
2418 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2419 of host_find_byname() use the default settings of RES_DEFNAMES
2420 (qualify_single) but not RES_DNSRCH (search_parents).
2421

PH
2422PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2423 spool_read_header() do less string testing, by means of a preliminary
2424 switch on the second character of optional "-foo" lines. (This is
2425 overdue, caused by the large number of possibilities that now exist.
2426 Originally there were few.) While I was there, I also converted the
2427 str(n)cmp tests so they don't re-test the leading "-" and the first
2428 character, in the hope this might squeeze out yet more improvement.

PH
2430PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2431 flag allowing group syntax was set by the header_syntax check but not
2432 turned off, possible causing trouble later; (2) The flag was not being
2433 set at all for the header_verify test, causing "group"-style headers to
2434 be rejected. I have now set it in this case, and also caused header_
2435 verify to ignore an empty address taken from a group. While doing this, I
2436 came across some other cases where the code for allowing group syntax
2437 while scanning a header line wasn't quite right (mostly, not resetting
2438 the flag correctly in the right place). These bugs could have caused
2439 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
2441PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2442 with the "reply" argument non-NULL. The code, however (which originally
2443 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2444 but it didn't always do it. This confused somebody who was copying the
2445 code for some other use. I have removed all the tests.
2446
411ef850
PH
2447PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2448 feature that was used to support insecure browsers during the U.S. crypto
2449 embargo. It requires special client support, and Exim is probably the
2450 only MTA that supported it -- and would never use it because real RSA is
2451 always available. This code has been removed, because it had the bad
2452 effect of slowing Exim down by computing (never used) parameters for the
2453 RSA_EXPORT functionality.
2454
7befa435
PH
2455PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2456 authenticator to fail if there's a tab character in the incoming data
2457 (there should never be unless someone is messing about, as it's supposed
2458 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2459 if the connection is using TLS or if the remote IP is the same as the
2460 local IP, and the "valid-client-cert option" if a client certificate has
2461 been verified.

2492
2493PH/30 Exim was sometimes attempting to deliver messages that had suffered
2494 address errors (4xx response to RCPT) over the same connection as other
2495 messages routed to the same hosts. Such deliveries are always "forced",
2496 so retry times are not inspected. This resulted in far too many retries
2497 for the affected addresses. The effect occurred only when there were more
2498 hosts than the hosts_max_try setting in the smtp transport when it had
2499 the 4xx errors. Those hosts that it had tried were not added to the list
2500 of hosts for which the message was waiting, so if all were tried, there
2501 was no problem. Two fixes have been applied:
2502
2503 (i) If there are any address or message errors in an SMTP delivery, none
2504 of the hosts (tried or untried) are now added to the list of hosts
2505 for which the message is waiting, so the message should not be a
2506 candidate for sending over the same connection that was used for a
2507 successful delivery of some other message. This seems entirely
2508 reasonable: after all the message is NOT "waiting for some host".
2509 This is so "obvious" that I'm not sure why it wasn't done
2510 previously. Hope I haven't missed anything, but it can't do any
2511 harm, as the worst effect is to miss an optimization.
2512
2513 (ii) If, despite (i), such a delivery is accidentally attempted, the
2514 routing retry time is respected, so at least it doesn't keep
2515 hammering the server.

2530PH/35 The error "getsockname() failed: connection reset by peer" was being
2531 written to the panic log as well as the main log, but it isn't really

2533 removed the panic log writing for the ECONNRESET error when getsockname()
2534 fails.
2535
48c7f9e2
PH
2536PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2537 runs only) independently of the message's sender address. This meant
2538 that, if the 4xx error was in fact related to the sender, a different
2539 message to the same recipient with a different sender could confuse
4c04137d 2540 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2541 server, but other circumstances could also provoke similar problems.
2542 I have changed the default so that the retry time for these errors is now
2543 based a combination of the sender and recipient addresses. This change
2544 can be overridden by setting address_retry_include_sender=false in the
2545 smtp transport.

2813PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2815 Unfortunately, if there is a major crisis, such as a disk failure,
2816 tcp-wrappers gives "deny", whereas what one would like would be some
2817 kind of temporary error. A kludge has been added to help with this.
2818 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2819 554 error is used if errno is still zero or contains ENOENT (which occurs
2820 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2821 451 error is used.

2857PH/01 The code for finding all the local interface addresses on a FreeBSD
2858 system running IPv6 was broken. This may well have applied to all BSD
2859 systems, as well as to others that have similar system calls. The broken
2860 code found IPv4 interfaces correctly, but gave incorrect values for the
2861 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2862 that it would not match correctly against @[] and not recognize the IPv6
2863 addresses as local.

2906 autoreply, Exim could try to deliver to a non-existent relative file

2941 additional section of a DNS packet that returns MX or SRV records.
2942 Instead, it always explicitly searches for A/AAAA records. This avoids
2943 major problems that occur when a DNS server includes only records of one
2944 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2945 fixed another bug: if SRV records were looked up and the corresponding
2946 address records were *not* found in the additional section, the port
2947 values from the SRV records were lost.

2949PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2957PH/19 When calculating a retry time, Exim used to measure the "time since
2958 failure" by looking at the "first failed" field in the retry record. Now
2959 it does not use this if it is later than than the arrival time of the
2960 message. Instead it uses the arrival time. This makes for better
2961 behaviour in cases where some deliveries succeed, thus re-setting the
2962 "first failed" field. An example is a quota failure for a huge message
2963 when small messages continue to be delivered. Without this change, the
2964 "time since failure" will always be short, possible causing more frequent
2965 delivery attempts for the huge message than are intended.

3065 files with open(), and sets the required mode explicitly. Thus, these
3066 files were ending up world-writeable. This was not a big issue, because,
3067 being within the spool directory, they were not world-accessible. I have
3068 created a function called modefopen, which takes an additional mode
3069 argument. It sets umask(777), creates the file, chmods it to the required
3070 mode, then resets the umask. All the relevant calls to fopen() in the

3084 they are received. Thus, the responses can be made to depend on the
3085 challenges. If an invalid string is ignored, an empty string is placed in
3086 the variable.

3097PH/50 When an Exim quota was set without a file count quota, and mailbox_size
3098 was also set, the appendfile transport was unnecessarily scanning a
3099 directory of message files (e.g. for maildir delivery) to find the count
3100 of files (along with the size), even though it did not need this
3101 information. It now does the scan only if it needs to find either the
3102 size of the count of files.

3106PH/52 Two bugs concerned with error handling when the smtp transport is
3107 used in LMTP mode:
3108
3109 (i) Exim was not creating retry information for temporary errors given
3110 for individual recipients after the DATA command when the smtp transport
3111 was used in LMTP mode. This meant that they could be retried too
3112 frequently, and not timed out correctly.
3113
3114 (ii) Exim was setting the flag that allows error details to be returned
3115 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3116 recipients that were returned after the DATA command.
3117
3118PH/53 This is related to PH/52, but is more general: for any failing address,
3119 when detailed error information was permitted to be returned to the
3120 sender, but the error was temporary, then after the final timeout, only
3121 "retry timeout exceeded" was returned. Now it returns the full error as
3122 well as "retry timeout exceeded".

3178PH/68 The bounce_return_message and bounce_return_body options were not being
3179 honoured for bounces generated during the reception of non-SMTP messages.
3180 In particular, this applied to messages rejected by the ACL. This bug has
3181 been fixed. However, if bounce_return_message is true and bounce_return_
3182 body is false, the headers that are returned for a non-SMTP message
3183 include only those that have been read before the error was detected.

PH
3192PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3193 function verify_get_ident() calls ip_connect() to connect a socket, but
3194 if the "connect()" function timed out, ip_connect() used to close the
3195 socket. However, verify_get_ident() also closes the socket later, and in
3196 between Exim writes to the log, which may get opened at this point. When
3197 the socket was closed in ip_connect(), the log could get the same file
3198 descriptor number as the socket. This naturally causes chaos. The fix is
3199 not to close the socket in ip_connect(); the socket should be closed by
3200 the function that creates it. There was only one place in the code where
3201 this was missing, in the iplookup router, which I don't think anybody now
3202 uses, but I've fixed it anyway.

3221PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3222
3223 (1) Generate an error if the third argument for the ${prvs expansion is
3224 not a single digit.
3225
3226 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3227 string.
3228
3229 (3) Reset the variables that are obtained from the first argument of
3230 ${prvscheck and used in the second argument before leaving the code,
3231 because their memory is reclaimed, so using them afterwards may do
3232 silly things.
3233
3234 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3235 one (it's much easier than Tom thought :-).
3236
3237 (5) Because of (4), we can now allow for the use of $prvscheck_result
3238 inside the third argument.

PH
3247PH/05 When a filter generated an autoreply, the entire To: header line was
3248 quoted in the delivery log line, like this:
3249
3250 => >A.N.Other <ano@some.domain> <original@ddress> ...
3251
3252 This has been changed so that it extracts the operative address. There
3253 may be more than one such address. If so, they are comma-separated, like
3254 this:
3255
3256 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
3258PH/06 When a client host used a correct literal IP address in a HELO or EHLO
3259 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3260 not being looked up in the rDNS to get a host name, Exim was showing the
3261 IP address twice in Received: lines, even though the IP addresses were
3262 identical. For example:
3263
3264 Received: from [1.2.3.4] (helo=[1.2.3.4])
3265
3266 However, if the real host name was known, it was omitting the HELO data
3267 if it matched the actual IP address. This has been tidied up so that it
3268 doesn't show the same IP address twice.

3270PH/07 When both +timestamp and +memory debugging was on, the value given by
3271 $tod_xxx expansions could be wrong, because the tod_stamp() function was
