9427e879 11JH/01 Bug 1922: Support IDNA2008. This has slightly different conversion rules
4c04137d 12 than -2003 did; needs libidn2 in addition to libidn.

20 missing a wire-to-host endian conversion.

JH
22JH/04 Bug 2004: fix CHUNKING in non-PIPELINEING mode. Chunk data following
23 close after a BDAT command line could be taken as a following command,
24 giving a synch failure. Fix by only checking for synch immediately
25 before acknowledging the chunk.

JH
31JH/05 Have the EHLO response advertise VRFY, if there is a vrfy ACL defined.
32 Previously we did not; the RFC seems ambiguous and VRFY is not listed
33 by IANA as a service extension. However, John Klensin suggests that we
34 should.
35
36JH/06 Bug 2017: Fix DKIM verification in -bh test mode. The data feed into
b895f4b2
JH
37 the dkim code may be unix-mode line endings rather than smtp wire-format
38 CRLF, so prepend a CR to any bare LF.
fd047340 39
bd8fbe36 40JH/07 Rationalise the coding for callout smtp conversations and transport ones.
902fbd69
JH
41 As a side-benfit, callouts can now use PIPELINING hence fewer round-trips.
42
bd8fbe36
JH
43JH/08 Bug 2016: Fix DKIM verification vs. CHUNKING. Any BDAT commands after
44 the first were themselves being wrongly included in the feed into dkim
45 processing; with most chunk sizes in use this resulted in an incorrect
46 body hash calculated value.
47

JH
48JH/09 Bug 2014: permit inclusion of a DKIM-Signature header in a received
49 DKIM signature block, for verification. Although advised against by
50 standards it is specifically not ruled illegal.

JH
52JH/10 Bug 2025: Fix reception of (quoted) local-parts with embedded spaces.
53
54JH/11 Bug 2029: Fix crash in DKIM verification when a message signature block is
55 missing a body hash (the bh= tag).
56
57JH/12 Bug 2018: Re-order Proxy Protocol startup versus TLS-on-connect startup.
58 It seems that HAProxy sends the Proxy Protocol information in clear and
59 only then does a TLS startup, so do the same.
60
61JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
62 TCP connections (such as for Spamd) unless the daemon successfully set
63 Fast Open mode on its listening sockets. This fixes breakage seen on
64 too-old kernels or those not configured for Fast Open, at the cost of
65 requiring both directions being enabled for TFO, and TFO never being used
66 by non-daemon-related Exim processes.
67
68JH/14 Bug 2000: Reject messages recieved with CHUNKING but with malformed line
69 endings, at least on the first header line. Try to canonify any that get
70 past that check, despite the cost.
71
b6040544
JH
72JH/15 Angle-bracket nesting (an error inserted by broken sendmails) levels are
73 now limited to an arbitrary five deep, while parsing addresses with the
74 strip_excess_angle_brackets option enabled.

76PP/03 Bug 2018: For Proxy Protocol and TLS-on-connect, do not over-read and
77 instead leave the unprompted TLS handshake in socket buffer for the
78 TLS library to consume.

83
90341c71
JH
84JH/16 Drop variables when they go out of scope. Memory management drops a whole
85 region in one operation, for speed, and this leaves assigned pointers
86 dangling. Add checks run only under the testsuite which checks all
87 variables at a store-reset and panics on a dangling pointer; add code
88 explicitly nulling out all the variables discovered. Fixes one known
89 bug: a transport crash, where a dangling pointer for $sending_ip_address
90 originally assigned in a verify callout, is re-used.
91
cf0c6164
JH
92JH/17 Rework error string handling in TLS interface so that the caller in
93 more cases is responsible for logging. This permits library-sourced
94 string to be attached to addresses during delivery, and collapses
95 pairs of long lines into single ones.

JH
101JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
102 supports it and a size is available (ie. the sending peer gave us one).
8d042305 103
03d5892b
JH
104JH/02 The obsolete acl condition "demime" is removed (finally, after ten
105 years of being deprecated). The replacements are the ACLs
106 acl_smtp_mime and acl_not_smtp_mime.
107
4b0fe319
JH
108JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
109 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
110 or even an in-clear connection were permitted. Now, if the host lookup
111 was dnssec and dane was requested then the host is only used if the
112 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
113 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
114 if one fails this test.
115 This means that a poorly-configured remote DNS will make it incommunicado;
116 but it protects against a DNS-interception attack on it.

JH
138JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
139 a cutthrough deliver is pending, as we always want to make a connection.
140 This also avoids re-routing the message when later placing the cutthrough
141 connection after a verify cache hit.
142 Do not update it with the verify result either.
143
144JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
145 when routing results in more than one destination address.
146
ae8386f0
JH
147JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
148 signing (which inhibits the cutthrough capability). Previously only
149 the presence of an option was tested; now an expansion evaluating as
150 empty is permissible (obviously it should depend only on data available
151 when the cutthrough connection is made).
152

153JH/14 Fix logging of errors under PIPELINING. Previously the log line giving
154 the relevant preceding SMTP command did not note the pipelining mode.

177JH/22 Fix continued use of a connection for further deliveries. If a port was
178 specified by a router, it must also match for the delivery to be
179 compatible.

JH
181JH/23 Bug 1874: fix continued use of a connection for further deliveries.
182 When one of the recipients of a message was unsuitable for the connection
183 (has no matching addresses), we lost track of needing to mark it
184 deferred. As a result mail would be lost.

254 The I= interface field on outgoing lines is now after the H= remote

259JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
260 If not running log_selector +smtp_connection the mainlog would be held
261 open indefinitely after a "too many connections" event, including to a
262 deleted file after a log rotate. Leave the per net connection logging
263 leaving it open for efficiency as that will be quickly detected by the
264 check on the next write.

930TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
931
932 When a queue runner is handling a message, Exim first routes the
933 recipient addresses, during which it prunes them based on the retry
934 hints database. After that it attempts to deliver the message to
935 any remaining recipients. It then updates the hints database using
936 the retry rules.
937
938 So if a recipient address works intermittently, it can get repeatedly
939 deferred at routing time. The retry hints record remains fresh so the
940 address never reaches the final cutoff time.
941
942 This is a fairly common occurrence when a user is bumping up against
943 their storage quota. Exim had some logic in its local delivery code
944 to deal with this. However it did not apply to per-recipient defers
945 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
946
1ddeb334
TF
947 This change adds a proper retry rule check during routing so that the
948 final cutoff time is checked against the message's age. We only do
949 this check if there is an address retry record and there is not a
950 domain retry record; this implies that previous attempts to handle
951 the address had the retry_use_local_parts option turned on. We use
952 this as an approximation for the destination being like a local
953 delivery, as in LMTP.
67bd1ab3
TF
954
955 I suspect this new check makes the old local delivery cutoff check
956 redundant, but I have not verified this so I left the code in place.

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

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

1278TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1279 lock up or crash if it happened to be inside a call to libc when it
1280 got a SIGUSR1 from exiwhat.
1281
1282 The SIGUSR1 handler appends the current process status to the process
1283 log which is later printed by exiwhat. It used to use the general
1284 purpose logging code to do this, but several functions it calls are
1285 not safe for signals.
1286
1287 The new output code in the SIGUSR1 handler is specific to the process
1288 log, and simple enough that it's easy to inspect for signal safety.
1289 Removing some special cases also simplifies the general logging code.
1290 Removing the spurious timestamps from the process log simplifies
1291 exiwhat.

TF
1293TF/04 Improved ratelimit ACL condition.
1294
1295 The /noupdate option has been deprecated in favour of /readonly which
1296 has clearer semantics. The /leaky, /strict, and /readonly update modes
1297 are mutually exclusive. The update mode is no longer included in the
1298 database key; it just determines when the database is updated. (This
4c04137d 1299 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1300
1301 Exim now checks that the per_* options are used with an update mode that
1302 makes sense for the current ACL. For example, when Exim is processing a
1303 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1304 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1305 must specify per_mail/readonly. If you omit the update mode it defaults to
1306 /leaky where that makes sense (as before) or /readonly where required.
1307
1308 The /noupdate option is now undocumented but still supported for
1309 backwards compatibility. It is equivalent to /readonly except that in
1310 ACLs where /readonly is required you may specify /leaky/noupdate or
1311 /strict/noupdate which are treated the same as /readonly.
1312
1313 A useful new feature is the /count= option. This is a generalization
1314 of the per_byte option, so that you can measure the throughput of other
1315 aggregate values. For example, the per_byte option is now equivalent
1316 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1317
1318 The per_rcpt option has been generalized using the /count= mechanism
1319 (though it's more complicated than the per_byte equivalence). When it is
1320 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1321 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1322 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1323 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1324 Note that using per_rcpt with a non-readonly update mode in more than
1325 one ACL will cause the recipients to be double-counted. (The per_mail
1326 and per_byte options don't have this problem.)
1327
1328 The handling of very low rates has changed slightly. If the computed rate
1329 is less than the event's count (usually one) then this event is the first
1330 after a long gap. In this case the rate is set to the same as this event's
1331 count, so that the first message of a spam run is counted properly.
1332
1333 The major new feature is a mechanism for counting the rate of unique
1334 events. The new per_addr option counts the number of different
1335 recipients that someone has sent messages to in the last time period. It
1336 behaves like per_rcpt if all the recipient addresses are different, but
1337 duplicate recipient addresses do not increase the measured rate. Like
1338 the /count= option this is a general mechanism, so the per_addr option
1339 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1340 example, measure the rate that a client uses different sender addresses
1341 with the options per_mail/unique=$sender_address. There are further
1342 details in the main documentation.

1893 were called 'true' and it seems that C99 defines that as a reserved

1915
6a3bceb1
PH
1916PH/02 When an IPv6 address is converted to a string for single-key lookup
1917 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1918 dots are used instead of colons so that keys in lsearch files need not
1919 contain colons. This was done some time before quoting was made available
1920 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1921 (notated using the quote facility) so as to distinguish them from IPv4
1922 keys. This meant that lookups for IP addresses in host lists did not work
1923 for iplsearch lookups.
1924
1925 This has been fixed by arranging for IPv6 addresses to be expressed with
1926 colons if the lookup type is iplsearch. This is not incompatible, because

1936MH/01 The "spam" ACL condition code contained a sscanf() call with a %s

1938 a rogue spamd server to cause a buffer overflow. While nobody in their
1939 right mind would setup Exim to query an untrusted spamd server, an
1940 attacker that gains access to a server running spamd could potentially
1941 exploit this vulnerability to run arbitrary code as the Exim user.

2137 some time before the response is written. In this time, more input might
2138 arrive, invalidly. So now there are extra checks after an ACL has run for
2139 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2140 pipelining has not been advertised.

2214 the response to the final '.' that terminates a message, but only in the
2215 case where the client has not sent further data following the '.'
2216 (unfortunately, this is allowed). However, in many cases there won't be
2217 any further data because there won't be any more messages to send. A call
2218 to select() can be used: if it shows that the input is "ready", there is
2219 either input waiting, or the socket has been closed. An attempt to read
2220 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2221 would have sent an OK response which the client would never have see.

2233 fixed by 4.65/MH/01 (is this a record?) are fixed:
2234
2235 (i) An empty string was always treated as zero by the numeric comparison
2236 operators. This behaviour has been restored.
2237
2238 (ii) It is documented that the numeric comparison operators always treat
2239 their arguments as decimal numbers. This was broken in that numbers
2240 starting with 0 were being interpreted as octal.
2241
2242 While fixing these problems I realized that there was another issue that
2243 hadn't been noticed. Values of message_size_limit (both the global option
2244 and the transport option) were treated as octal if they started with 0.
2245 The documentation was vague. These values are now always treated as
2246 decimal, and I will make that clear in the documentation.

PH
2290PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2291 callout verification, Exim cached a "reject" for the entire domain. This
2292 is correct for most verifications, but it is not correct for a recipient
2293 verification with use_sender or use_postmaster set, because in that case
2294 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2295 case of MAIL FROM:<> rejection from other early rejections (e.g.
2296 rejection of HELO). When verifying a recipient using a non-null MAIL
2297 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2298 Whatever the result of the callout, the value of the domain cache is
2299 left unchanged (for any other kind of callout, getting as far as trying
2300 RCPT means that the domain itself is ok).

2334PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2335 hostname. This is wrong, because it relates to the incoming message (and
2336 probably the interface on which it is arriving) and not to the outgoing
2337 callout (which could be using a different interface). This has been
2338 changed to use the value of the helo_data option from the smtp transport
2339 instead - this is what is used when a message is actually being sent. If
2340 there is no remote transport (possible with a router that sets up host
2341 addresses), $smtp_active_hostname is used.

14aa5a05 2343PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2344 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2345 (a) The code assumed that strncpy() returns a negative number on buffer
2346 overflow, which isn't the case. Replaced with Exim's string_format()
2347 function.
2348 (b) There were several signed/unsigned issues. I just did the minimum
2349 hacking in of casts. There is scope for a larger refactoring.
2350 (c) The code used strcasecmp() which is not a standard C function.
2351 Replaced with Exim's strcmpic() function.
2352 (d) The code set only $1; it now sets $auth1 as well.
2353 (e) A simple test gave the error "authentication client didn't specify
2354 service in request". It would seem that Dovecot has changed its
2355 interface. Fortunately there's a specification; I followed it and
2356 changed what the client sends and it appears to be working now.

PH
2361PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2362 address A is aliased to B and C, where B exists and C does not. Without
2363 -v the output is "A verified" because verification stops after a
2364 successful redirection if more than one address is generated. However,
2365 with -v the child addresses are also verified. Exim was outputting "A
2366 failed to verify" and then showing the successful verification for C,
2367 with its parentage. It now outputs "B failed to verify", showing B's
2368 parentage before showing the successful verification of C.

PH
2370PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
2371 look up a TXT record in a specific list after matching in a combined
2372 list.
2373
322050c2
PH
2374PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2375 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2376 they consult the DNS. I had assumed they would set it the way they
2377 wanted; and indeed my experiments on Linux seem to show that in some
2378 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2379 To be on the safe side, however, I have now made the interface to
2380 host_find_byname() similar to host_find_bydns(), with an argument
2381 containing the DNS resolver options. The host_find_byname() function now
2382 sets these options at its start, just as host_find_bydns() does. The smtp
2383 transport options dns_qualify_single and dns_search_parents are passed to
2384 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2385 of host_find_byname() use the default settings of RES_DEFNAMES
2386 (qualify_single) but not RES_DNSRCH (search_parents).
2387

PH
2388PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2389 spool_read_header() do less string testing, by means of a preliminary
2390 switch on the second character of optional "-foo" lines. (This is
2391 overdue, caused by the large number of possibilities that now exist.
2392 Originally there were few.) While I was there, I also converted the
2393 str(n)cmp tests so they don't re-test the leading "-" and the first
2394 character, in the hope this might squeeze out yet more improvement.
2395

PH
2396PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2397 flag allowing group syntax was set by the header_syntax check but not
2398 turned off, possible causing trouble later; (2) The flag was not being
2399 set at all for the header_verify test, causing "group"-style headers to
2400 be rejected. I have now set it in this case, and also caused header_
2401 verify to ignore an empty address taken from a group. While doing this, I
2402 came across some other cases where the code for allowing group syntax
2403 while scanning a header line wasn't quite right (mostly, not resetting
2404 the flag correctly in the right place). These bugs could have caused
2405 trouble for malformed header lines. I hope it is now all correct.
2406
602e59e5
PH
2407PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2408 with the "reply" argument non-NULL. The code, however (which originally
2409 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2410 but it didn't always do it. This confused somebody who was copying the
2411 code for some other use. I have removed all the tests.
2412
411ef850
PH
2413PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2414 feature that was used to support insecure browsers during the U.S. crypto
2415 embargo. It requires special client support, and Exim is probably the
2416 only MTA that supported it -- and would never use it because real RSA is
2417 always available. This code has been removed, because it had the bad
2418 effect of slowing Exim down by computing (never used) parameters for the
2419 RSA_EXPORT functionality.
2420
7befa435
PH
2421PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2422 authenticator to fail if there's a tab character in the incoming data
2423 (there should never be unless someone is messing about, as it's supposed
2424 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2425 if the connection is using TLS or if the remote IP is the same as the
2426 local IP, and the "valid-client-cert option" if a client certificate has
2427 been verified.

PH
2458
2459PH/30 Exim was sometimes attempting to deliver messages that had suffered
2460 address errors (4xx response to RCPT) over the same connection as other
2461 messages routed to the same hosts. Such deliveries are always "forced",
2462 so retry times are not inspected. This resulted in far too many retries
2463 for the affected addresses. The effect occurred only when there were more
2464 hosts than the hosts_max_try setting in the smtp transport when it had
2465 the 4xx errors. Those hosts that it had tried were not added to the list
2466 of hosts for which the message was waiting, so if all were tried, there
2467 was no problem. Two fixes have been applied:
2468
2469 (i) If there are any address or message errors in an SMTP delivery, none
2470 of the hosts (tried or untried) are now added to the list of hosts
2471 for which the message is waiting, so the message should not be a
2472 candidate for sending over the same connection that was used for a
2473 successful delivery of some other message. This seems entirely
2474 reasonable: after all the message is NOT "waiting for some host".
2475 This is so "obvious" that I'm not sure why it wasn't done
2476 previously. Hope I haven't missed anything, but it can't do any
2477 harm, as the worst effect is to miss an optimization.
2478
2479 (ii) If, despite (i), such a delivery is accidentally attempted, the
2480 routing retry time is respected, so at least it doesn't keep
2481 hammering the server.

2496PH/35 The error "getsockname() failed: connection reset by peer" was being
2497 written to the panic log as well as the main log, but it isn't really

2499 removed the panic log writing for the ECONNRESET error when getsockname()
2500 fails.
2501
48c7f9e2
PH
2502PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2503 runs only) independently of the message's sender address. This meant
2504 that, if the 4xx error was in fact related to the sender, a different
2505 message to the same recipient with a different sender could confuse
4c04137d 2506 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2507 server, but other circumstances could also provoke similar problems.
2508 I have changed the default so that the retry time for these errors is now
2509 based a combination of the sender and recipient addresses. This change
2510 can be overridden by setting address_retry_include_sender=false in the
2511 smtp transport.

2779PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2781 Unfortunately, if there is a major crisis, such as a disk failure,
2782 tcp-wrappers gives "deny", whereas what one would like would be some
2783 kind of temporary error. A kludge has been added to help with this.
2784 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2785 554 error is used if errno is still zero or contains ENOENT (which occurs
2786 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2787 451 error is used.

2823PH/01 The code for finding all the local interface addresses on a FreeBSD
2824 system running IPv6 was broken. This may well have applied to all BSD
2825 systems, as well as to others that have similar system calls. The broken
2826 code found IPv4 interfaces correctly, but gave incorrect values for the
2827 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2828 that it would not match correctly against @[] and not recognize the IPv6
2829 addresses as local.

2872 autoreply, Exim could try to deliver to a non-existent relative file

2908 Instead, it always explicitly searches for A/AAAA records. This avoids
2909 major problems that occur when a DNS server includes only records of one
2910 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2911 fixed another bug: if SRV records were looked up and the corresponding
2912 address records were *not* found in the additional section, the port
2913 values from the SRV records were lost.

2915PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2923PH/19 When calculating a retry time, Exim used to measure the "time since
2924 failure" by looking at the "first failed" field in the retry record. Now
2925 it does not use this if it is later than than the arrival time of the
2926 message. Instead it uses the arrival time. This makes for better
2927 behaviour in cases where some deliveries succeed, thus re-setting the
2928 "first failed" field. An example is a quota failure for a huge message
2929 when small messages continue to be delivered. Without this change, the
2930 "time since failure" will always be short, possible causing more frequent
2931 delivery attempts for the huge message than are intended.

3031 files with open(), and sets the required mode explicitly. Thus, these
3032 files were ending up world-writeable. This was not a big issue, because,
3033 being within the spool directory, they were not world-accessible. I have
3034 created a function called modefopen, which takes an additional mode
3035 argument. It sets umask(777), creates the file, chmods it to the required
3036 mode, then resets the umask. All the relevant calls to fopen() in the

3078 frequently, and not timed out correctly.
3079
3080 (ii) Exim was setting the flag that allows error details to be returned
3081 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3082 recipients that were returned after the DATA command.
3083
3084PH/53 This is related to PH/52, but is more general: for any failing address,
3085 when detailed error information was permitted to be returned to the
3086 sender, but the error was temporary, then after the final timeout, only
3087 "retry timeout exceeded" was returned. Now it returns the full error as
3088 well as "retry timeout exceeded".

3126PH/62 When verifying, if an address was redirected to one new address, so that
3127 verification continued, and the new address failed or deferred after

3129 passed back to the ACL. This was different to the case when no
3130 redirection occurred. The value is now passed back in both cases.

3144PH/68 The bounce_return_message and bounce_return_body options were not being
3145 honoured for bounces generated during the reception of non-SMTP messages.
3146 In particular, this applied to messages rejected by the ACL. This bug has
3147 been fixed. However, if bounce_return_message is true and bounce_return_
3148 body is false, the headers that are returned for a non-SMTP message
3149 include only those that have been read before the error was detected.
3150 (In the case of an ACL rejection, they have all been read.)

3152PH/69 The HTML version of the specification is now built in a directory called

3158PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3159 function verify_get_ident() calls ip_connect() to connect a socket, but
3160 if the "connect()" function timed out, ip_connect() used to close the
3161 socket. However, verify_get_ident() also closes the socket later, and in
3162 between Exim writes to the log, which may get opened at this point. When
3163 the socket was closed in ip_connect(), the log could get the same file
3164 descriptor number as the socket. This naturally causes chaos. The fix is
3165 not to close the socket in ip_connect(); the socket should be closed by
3166 the function that creates it. There was only one place in the code where
3167 this was missing, in the iplookup router, which I don't think anybody now
3168 uses, but I've fixed it anyway.

3182
3183 (2) Add control=submission to the relay_from_hosts and authenticated
3184 clients checks, on the grounds that messages accepted by these
3185 statements are most likely to be submissions.

3187PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3188
3189 (1) Generate an error if the third argument for the ${prvs expansion is
3190 not a single digit.
3191
3192 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3193 string.
3194
3195 (3) Reset the variables that are obtained from the first argument of
3196 ${prvscheck and used in the second argument before leaving the code,
3197 because their memory is reclaimed, so using them afterwards may do
3198 silly things.
3199
3200 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3201 one (it's much easier than Tom thought :-).
3202
3203 (5) Because of (4), we can now allow for the use of $prvscheck_result
3204 inside the third argument.

3213PH/05 When a filter generated an autoreply, the entire To: header line was
3214 quoted in the delivery log line, like this:
3215
3216 => >A.N.Other <ano@some.domain> <original@ddress> ...
3217
3218 This has been changed so that it extracts the operative address. There
3219 may be more than one such address. If so, they are comma-separated, like
3220 this:
3221
3222 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
3224PH/06 When a client host used a correct literal IP address in a HELO or EHLO
3225 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3226 not being looked up in the rDNS to get a host name, Exim was showing the
3227 IP address twice in Received: lines, even though the IP addresses were
3228 identical. For example:
3229
3230 Received: from [1.2.3.4] (helo=[1.2.3.4])
3231
3232 However, if the real host name was known, it was omitting the HELO data
3233 if it matched the actual IP address. This has been tidied up so that it
3234 doesn't show the same IP address twice.

3236PH/07 When both +timestamp and +memory debugging was on, the value given by

3260PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

3263 Auto-submitted: auto-generated
3264
3265 in the messages that it generates (bounce messages and others, such as
4c04137d 3266 warnings). In the case of bounce messages for non-SMTP messages, there was
456682f5
PH
3267 also a typo: it was using "Auto_submitted" (underscore instead of
3268 hyphen). Since every message generated by Exim is necessarily in response
3269 to another message, thes have all been changed to:
3270
3271 Auto-Submitted: auto-replied
3272
3273 in accordance with these statements in the RFC:
3274
3275 The auto-replied keyword:
3276
3277 - SHOULD be used on messages sent in direct response to another
3278 message by an automatic process,
3279
3280 - MUST NOT be used on manually-generated messages,
3281
3282 - MAY be used on Delivery Status Notifications (DSNs) and Message
3283 Disposition Notifications (MDNs),
3284
3285 - MUST NOT be used on messages generated by automatic or periodic
3286 processes, except for messages which are automatic responses to
3287 other messages.
