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.

9427e879 20JH/01 Bug 1922: Support IDNA2008. This has slightly different conversion rules
4c04137d 21 than -2003 did; needs libidn2 in addition to libidn.

31JH/04 Bug 2004: fix CHUNKING in non-PIPELINEING mode. Chunk data following
32 close after a BDAT command line could be taken as a following command,
33 giving a synch failure. Fix by only checking for synch immediately
34 before acknowledging the chunk.

40JH/05 Have the EHLO response advertise VRFY, if there is a vrfy ACL defined.
41 Previously we did not; the RFC seems ambiguous and VRFY is not listed
42 by IANA as a service extension. However, John Klensin suggests that we
43 should.
44
45JH/06 Bug 2017: Fix DKIM verification in -bh test mode. The data feed into
b895f4b2
JH
46 the dkim code may be unix-mode line endings rather than smtp wire-format
47 CRLF, so prepend a CR to any bare LF.

bd8fbe36 49JH/07 Rationalise the coding for callout smtp conversations and transport ones.
902fbd69
JH
50 As a side-benfit, callouts can now use PIPELINING hence fewer round-trips.
51
bd8fbe36
JH
52JH/08 Bug 2016: Fix DKIM verification vs. CHUNKING. Any BDAT commands after
53 the first were themselves being wrongly included in the feed into dkim
54 processing; with most chunk sizes in use this resulted in an incorrect
55 body hash calculated value.
56

JH
57JH/09 Bug 2014: permit inclusion of a DKIM-Signature header in a received
58 DKIM signature block, for verification. Although advised against by
59 standards it is specifically not ruled illegal.

JH
61JH/10 Bug 2025: Fix reception of (quoted) local-parts with embedded spaces.
62
63JH/11 Bug 2029: Fix crash in DKIM verification when a message signature block is
64 missing a body hash (the bh= tag).
65
66JH/12 Bug 2018: Re-order Proxy Protocol startup versus TLS-on-connect startup.
67 It seems that HAProxy sends the Proxy Protocol information in clear and
68 only then does a TLS startup, so do the same.
69
70JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
71 TCP connections (such as for Spamd) unless the daemon successfully set
72 Fast Open mode on its listening sockets. This fixes breakage seen on
73 too-old kernels or those not configured for Fast Open, at the cost of
74 requiring both directions being enabled for TFO, and TFO never being used
75 by non-daemon-related Exim processes.
76
77JH/14 Bug 2000: Reject messages recieved with CHUNKING but with malformed line
78 endings, at least on the first header line. Try to canonify any that get
79 past that check, despite the cost.
80

JH
81JH/15 Angle-bracket nesting (an error inserted by broken sendmails) levels are
82 now limited to an arbitrary five deep, while parsing addresses with the
83 strip_excess_angle_brackets option enabled.

85PP/03 Bug 2018: For Proxy Protocol and TLS-on-connect, do not over-read and
86 instead leave the unprompted TLS handshake in socket buffer for the
87 TLS library to consume.

92
90341c71
JH
93JH/16 Drop variables when they go out of scope. Memory management drops a whole
94 region in one operation, for speed, and this leaves assigned pointers
95 dangling. Add checks run only under the testsuite which checks all
96 variables at a store-reset and panics on a dangling pointer; add code
97 explicitly nulling out all the variables discovered. Fixes one known
98 bug: a transport crash, where a dangling pointer for $sending_ip_address
99 originally assigned in a verify callout, is re-used.

113JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
114 supports it and a size is available (ie. the sending peer gave us one).

JH
116JH/02 The obsolete acl condition "demime" is removed (finally, after ten
117 years of being deprecated). The replacements are the ACLs
118 acl_smtp_mime and acl_not_smtp_mime.
119
4b0fe319
JH
120JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
121 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
122 or even an in-clear connection were permitted. Now, if the host lookup
123 was dnssec and dane was requested then the host is only used if the
124 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
125 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
126 if one fails this test.
127 This means that a poorly-configured remote DNS will make it incommunicado;
128 but it protects against a DNS-interception attack on it.

148 certificate).
149
98c82a3d
JH
150JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
151 a cutthrough deliver is pending, as we always want to make a connection.
152 This also avoids re-routing the message when later placing the cutthrough
153 connection after a verify cache hit.
154 Do not update it with the verify result either.
155
156JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
157 when routing results in more than one destination address.
158
ae8386f0
JH
159JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
160 signing (which inhibits the cutthrough capability). Previously only
161 the presence of an option was tested; now an expansion evaluating as
162 empty is permissible (obviously it should depend only on data available
163 when the cutthrough connection is made).
164

165JH/14 Fix logging of errors under PIPELINING. Previously the log line giving
166 the relevant preceding SMTP command did not note the pipelining mode.

189JH/22 Fix continued use of a connection for further deliveries. If a port was
190 specified by a router, it must also match for the delivery to be
191 compatible.

JH
193JH/23 Bug 1874: fix continued use of a connection for further deliveries.
194 When one of the recipients of a message was unsuitable for the connection
195 (has no matching addresses), we lost track of needing to mark it
196 deferred. As a result mail would be lost.

257JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
258 and 3.4.4 - once the server is enabled to respond to an OCSP request
259 it does even when not requested, resulting in a stapling non-aware

265TF/02 Improve the consistency of logging incoming and outgoing interfaces.
266 The I= interface field on outgoing lines is now after the H= remote

271JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
272 If not running log_selector +smtp_connection the mainlog would be held
273 open indefinitely after a "too many connections" event, including to a
274 deleted file after a log rotate. Leave the per net connection logging
275 leaving it open for efficiency as that will be quickly detected by the
276 check on the next write.

942TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
943
944 When a queue runner is handling a message, Exim first routes the
945 recipient addresses, during which it prunes them based on the retry
946 hints database. After that it attempts to deliver the message to
947 any remaining recipients. It then updates the hints database using
948 the retry rules.
949
950 So if a recipient address works intermittently, it can get repeatedly
951 deferred at routing time. The retry hints record remains fresh so the
952 address never reaches the final cutoff time.
953
954 This is a fairly common occurrence when a user is bumping up against
955 their storage quota. Exim had some logic in its local delivery code
956 to deal with this. However it did not apply to per-recipient defers
957 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
958
1ddeb334
TF
959 This change adds a proper retry rule check during routing so that the
960 final cutoff time is checked against the message's age. We only do
961 this check if there is an address retry record and there is not a
962 domain retry record; this implies that previous attempts to handle
963 the address had the retry_use_local_parts option turned on. We use
964 this as an approximation for the destination being like a local
965 delivery, as in LMTP.
67bd1ab3
TF
966
967 I suspect this new check makes the old local delivery cutoff check
968 redundant, but I have not verified this so I left the code in place.

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

TF
1290TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1291 lock up or crash if it happened to be inside a call to libc when it
1292 got a SIGUSR1 from exiwhat.
1293
1294 The SIGUSR1 handler appends the current process status to the process
1295 log which is later printed by exiwhat. It used to use the general
1296 purpose logging code to do this, but several functions it calls are
1297 not safe for signals.
1298
1299 The new output code in the SIGUSR1 handler is specific to the process
1300 log, and simple enough that it's easy to inspect for signal safety.
1301 Removing some special cases also simplifies the general logging code.
1302 Removing the spurious timestamps from the process log simplifies
1303 exiwhat.
1304
c99ce5c9
TF
1305TF/04 Improved ratelimit ACL condition.
1306
1307 The /noupdate option has been deprecated in favour of /readonly which
1308 has clearer semantics. The /leaky, /strict, and /readonly update modes
1309 are mutually exclusive. The update mode is no longer included in the
1310 database key; it just determines when the database is updated. (This
4c04137d 1311 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1312
1313 Exim now checks that the per_* options are used with an update mode that
1314 makes sense for the current ACL. For example, when Exim is processing a
1315 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1316 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1317 must specify per_mail/readonly. If you omit the update mode it defaults to
1318 /leaky where that makes sense (as before) or /readonly where required.
1319
1320 The /noupdate option is now undocumented but still supported for
1321 backwards compatibility. It is equivalent to /readonly except that in
1322 ACLs where /readonly is required you may specify /leaky/noupdate or
1323 /strict/noupdate which are treated the same as /readonly.
1324
1325 A useful new feature is the /count= option. This is a generalization
1326 of the per_byte option, so that you can measure the throughput of other
1327 aggregate values. For example, the per_byte option is now equivalent
1328 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1329
1330 The per_rcpt option has been generalized using the /count= mechanism
1331 (though it's more complicated than the per_byte equivalence). When it is
1332 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1333 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1334 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1335 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1336 Note that using per_rcpt with a non-readonly update mode in more than
1337 one ACL will cause the recipients to be double-counted. (The per_mail
1338 and per_byte options don't have this problem.)
1339
1340 The handling of very low rates has changed slightly. If the computed rate
1341 is less than the event's count (usually one) then this event is the first
1342 after a long gap. In this case the rate is set to the same as this event's
1343 count, so that the first message of a spam run is counted properly.
1344
1345 The major new feature is a mechanism for counting the rate of unique
1346 events. The new per_addr option counts the number of different
1347 recipients that someone has sent messages to in the last time period. It
1348 behaves like per_rcpt if all the recipient addresses are different, but
1349 duplicate recipient addresses do not increase the measured rate. Like
1350 the /count= option this is a general mechanism, so the per_addr option
1351 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1352 example, measure the rate that a client uses different sender addresses
1353 with the options per_mail/unique=$sender_address. There are further
1354 details in the main documentation.

1567 the case, and it resulted in successful deliveries going unlogged.

1931 contain colons. This was done some time before quoting was made available
1932 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1933 (notated using the quote facility) so as to distinguish them from IPv4
1934 keys. This meant that lookups for IP addresses in host lists did not work
1935 for iplsearch lookups.
1936
1937 This has been fixed by arranging for IPv6 addresses to be expressed with
1938 colons if the lookup type is iplsearch. This is not incompatible, because
1939 previously such lookups could never work.
1940
4c04137d 1941 The situation is now rather anomalous, since one *can* have colons in

1942 ordinary lsearch keys. However, making the change in all cases is
1943 incompatible and would probably break a number of configurations.

1948MH/01 The "spam" ACL condition code contained a sscanf() call with a %s

1950 a rogue spamd server to cause a buffer overflow. While nobody in their
1951 right mind would setup Exim to query an untrusted spamd server, an

1953 exploit this vulnerability to run arbitrary code as the Exim user.

2150 arrive, invalidly. So now there are extra checks after an ACL has run for

2226 the response to the final '.' that terminates a message, but only in the
2227 case where the client has not sent further data following the '.'
2228 (unfortunately, this is allowed). However, in many cases there won't be
2229 any further data because there won't be any more messages to send. A call
2230 to select() can be used: if it shows that the input is "ready", there is
2231 either input waiting, or the socket has been closed. An attempt to read
2232 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2233 would have sent an OK response which the client would never have see.

2245 fixed by 4.65/MH/01 (is this a record?) are fixed:
2246
2247 (i) An empty string was always treated as zero by the numeric comparison
2248 operators. This behaviour has been restored.
2249
2250 (ii) It is documented that the numeric comparison operators always treat
2251 their arguments as decimal numbers. This was broken in that numbers
2252 starting with 0 were being interpreted as octal.
2253
2254 While fixing these problems I realized that there was another issue that
2255 hadn't been noticed. Values of message_size_limit (both the global option
2256 and the transport option) were treated as octal if they started with 0.
2257 The documentation was vague. These values are now always treated as
2258 decimal, and I will make that clear in the documentation.

PH
2302PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2303 callout verification, Exim cached a "reject" for the entire domain. This
2304 is correct for most verifications, but it is not correct for a recipient
2305 verification with use_sender or use_postmaster set, because in that case
2306 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2307 case of MAIL FROM:<> rejection from other early rejections (e.g.
2308 rejection of HELO). When verifying a recipient using a non-null MAIL
2309 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2310 Whatever the result of the callout, the value of the domain cache is
2311 left unchanged (for any other kind of callout, getting as far as trying
2312 RCPT means that the domain itself is ok).

2346PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2347 hostname. This is wrong, because it relates to the incoming message (and
2348 probably the interface on which it is arriving) and not to the outgoing
2349 callout (which could be using a different interface). This has been
2350 changed to use the value of the helo_data option from the smtp transport
2351 instead - this is what is used when a message is actually being sent. If
2352 there is no remote transport (possible with a router that sets up host
2353 addresses), $smtp_active_hostname is used.

14aa5a05 2355PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2356 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2357 (a) The code assumed that strncpy() returns a negative number on buffer
2358 overflow, which isn't the case. Replaced with Exim's string_format()
2359 function.
2360 (b) There were several signed/unsigned issues. I just did the minimum
2361 hacking in of casts. There is scope for a larger refactoring.
2362 (c) The code used strcasecmp() which is not a standard C function.
2363 Replaced with Exim's strcmpic() function.
2364 (d) The code set only $1; it now sets $auth1 as well.
2365 (e) A simple test gave the error "authentication client didn't specify
2366 service in request". It would seem that Dovecot has changed its
2367 interface. Fortunately there's a specification; I followed it and
2368 changed what the client sends and it appears to be working now.

2373PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2374 address A is aliased to B and C, where B exists and C does not. Without
2375 -v the output is "A verified" because verification stops after a
2376 successful redirection if more than one address is generated. However,
2377 with -v the child addresses are also verified. Exim was outputting "A
2378 failed to verify" and then showing the successful verification for C,
2379 with its parentage. It now outputs "B failed to verify", showing B's
2380 parentage before showing the successful verification of C.

2385
322050c2
PH
2386PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2387 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2388 they consult the DNS. I had assumed they would set it the way they
2389 wanted; and indeed my experiments on Linux seem to show that in some
2390 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2391 To be on the safe side, however, I have now made the interface to
2392 host_find_byname() similar to host_find_bydns(), with an argument
2393 containing the DNS resolver options. The host_find_byname() function now
2394 sets these options at its start, just as host_find_bydns() does. The smtp
2395 transport options dns_qualify_single and dns_search_parents are passed to
2396 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2397 of host_find_byname() use the default settings of RES_DEFNAMES
2398 (qualify_single) but not RES_DNSRCH (search_parents).

PH
2400PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2401 spool_read_header() do less string testing, by means of a preliminary
2402 switch on the second character of optional "-foo" lines. (This is
2403 overdue, caused by the large number of possibilities that now exist.
2404 Originally there were few.) While I was there, I also converted the
2405 str(n)cmp tests so they don't re-test the leading "-" and the first
2406 character, in the hope this might squeeze out yet more improvement.

PH
2408PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2409 flag allowing group syntax was set by the header_syntax check but not
2410 turned off, possible causing trouble later; (2) The flag was not being
2411 set at all for the header_verify test, causing "group"-style headers to
2412 be rejected. I have now set it in this case, and also caused header_
2413 verify to ignore an empty address taken from a group. While doing this, I
2414 came across some other cases where the code for allowing group syntax
2415 while scanning a header line wasn't quite right (mostly, not resetting
2416 the flag correctly in the right place). These bugs could have caused
2417 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
2419PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2420 with the "reply" argument non-NULL. The code, however (which originally
2421 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2422 but it didn't always do it. This confused somebody who was copying the
2423 code for some other use. I have removed all the tests.

411ef850
PH
2425PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2426 feature that was used to support insecure browsers during the U.S. crypto
2427 embargo. It requires special client support, and Exim is probably the
2428 only MTA that supported it -- and would never use it because real RSA is
2429 always available. This code has been removed, because it had the bad
2430 effect of slowing Exim down by computing (never used) parameters for the
2431 RSA_EXPORT functionality.

7befa435
PH
2433PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2434 authenticator to fail if there's a tab character in the incoming data
2435 (there should never be unless someone is messing about, as it's supposed
2436 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2437 if the connection is using TLS or if the remote IP is the same as the
2438 local IP, and the "valid-client-cert option" if a client certificate has
2439 been verified.

2470
2471PH/30 Exim was sometimes attempting to deliver messages that had suffered
2472 address errors (4xx response to RCPT) over the same connection as other
2473 messages routed to the same hosts. Such deliveries are always "forced",
2474 so retry times are not inspected. This resulted in far too many retries
2475 for the affected addresses. The effect occurred only when there were more
2476 hosts than the hosts_max_try setting in the smtp transport when it had
2477 the 4xx errors. Those hosts that it had tried were not added to the list
2478 of hosts for which the message was waiting, so if all were tried, there
2479 was no problem. Two fixes have been applied:
2480
2481 (i) If there are any address or message errors in an SMTP delivery, none
2482 of the hosts (tried or untried) are now added to the list of hosts
2483 for which the message is waiting, so the message should not be a
2484 candidate for sending over the same connection that was used for a
2485 successful delivery of some other message. This seems entirely
2486 reasonable: after all the message is NOT "waiting for some host".
2487 This is so "obvious" that I'm not sure why it wasn't done
2488 previously. Hope I haven't missed anything, but it can't do any
2489 harm, as the worst effect is to miss an optimization.
2490
2491 (ii) If, despite (i), such a delivery is accidentally attempted, the
2492 routing retry time is respected, so at least it doesn't keep
2493 hammering the server.

2509 written to the panic log as well as the main log, but it isn't really

2511 removed the panic log writing for the ECONNRESET error when getsockname()
2512 fails.

48c7f9e2
PH
2514PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2515 runs only) independently of the message's sender address. This meant
2516 that, if the 4xx error was in fact related to the sender, a different
2517 message to the same recipient with a different sender could confuse
4c04137d 2518 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2519 server, but other circumstances could also provoke similar problems.
2520 I have changed the default so that the retry time for these errors is now
2521 based a combination of the sender and recipient addresses. This change
2522 can be overridden by setting address_retry_include_sender=false in the
2523 smtp transport.

2791PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
2792 "Deny" causes Exim to reject the incoming connection with a 554 error.
2793 Unfortunately, if there is a major crisis, such as a disk failure,
2794 tcp-wrappers gives "deny", whereas what one would like would be some
2795 kind of temporary error. A kludge has been added to help with this.
2796 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2797 554 error is used if errno is still zero or contains ENOENT (which occurs
2798 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2799 451 error is used.

2835PH/01 The code for finding all the local interface addresses on a FreeBSD
2836 system running IPv6 was broken. This may well have applied to all BSD
2837 systems, as well as to others that have similar system calls. The broken
2838 code found IPv4 interfaces correctly, but gave incorrect values for the
2839 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2840 that it would not match correctly against @[] and not recognize the IPv6
2841 addresses as local.

2884 autoreply, Exim could try to deliver to a non-existent relative file

2919 additional section of a DNS packet that returns MX or SRV records.
2920 Instead, it always explicitly searches for A/AAAA records. This avoids
2921 major problems that occur when a DNS server includes only records of one
2922 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2923 fixed another bug: if SRV records were looked up and the corresponding
2924 address records were *not* found in the additional section, the port
2925 values from the SRV records were lost.

2927PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2935PH/19 When calculating a retry time, Exim used to measure the "time since
2936 failure" by looking at the "first failed" field in the retry record. Now
2937 it does not use this if it is later than than the arrival time of the
2938 message. Instead it uses the arrival time. This makes for better
2939 behaviour in cases where some deliveries succeed, thus re-setting the
2940 "first failed" field. An example is a quota failure for a huge message
2941 when small messages continue to be delivered. Without this change, the
2942 "time since failure" will always be short, possible causing more frequent
2943 delivery attempts for the huge message than are intended.

3040PH/42 The content-scanning code uses fopen() to create files in which to put

3043 files with open(), and sets the required mode explicitly. Thus, these
3044 files were ending up world-writeable. This was not a big issue, because,
3045 being within the spool directory, they were not world-accessible. I have
3046 created a function called modefopen, which takes an additional mode
3047 argument. It sets umask(777), creates the file, chmods it to the required
3048 mode, then resets the umask. All the relevant calls to fopen() in the

3084PH/52 Two bugs concerned with error handling when the smtp transport is
3085 used in LMTP mode:
3086
3087 (i) Exim was not creating retry information for temporary errors given
3088 for individual recipients after the DATA command when the smtp transport
3089 was used in LMTP mode. This meant that they could be retried too
3090 frequently, and not timed out correctly.
3091
3092 (ii) Exim was setting the flag that allows error details to be returned
3093 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3094 recipients that were returned after the DATA command.
3095
3096PH/53 This is related to PH/52, but is more general: for any failing address,
3097 when detailed error information was permitted to be returned to the
3098 sender, but the error was temporary, then after the final timeout, only
3099 "retry timeout exceeded" was returned. Now it returns the full error as
3100 well as "retry timeout exceeded".

3138PH/62 When verifying, if an address was redirected to one new address, so that
3139 verification continued, and the new address failed or deferred after
3140 having set something in $address_data, the value of $address_data was not
3141 passed back to the ACL. This was different to the case when no
3142 redirection occurred. The value is now passed back in both cases.

3144PH/63 Changed the macro HAVE_LOGIN_CAP (see PH/41 for this release above) to
3145 HAVE_SETCLASSRESOURCES because there are different APIs in use that all
3146 use login_cap.h, so on its own it isn't the distinguishing feature. The
3147 new name refers directly to the setclassresources() function.

PH
3156PH/68 The bounce_return_message and bounce_return_body options were not being
3157 honoured for bounces generated during the reception of non-SMTP messages.
3158 In particular, this applied to messages rejected by the ACL. This bug has
3159 been fixed. However, if bounce_return_message is true and bounce_return_
3160 body is false, the headers that are returned for a non-SMTP message
3161 include only those that have been read before the error was detected.
3162 (In the case of an ACL rejection, they have all been read.)

3164PH/69 The HTML version of the specification is now built in a directory called
3165 spec_html instead of spec.html, because the latter looks like a path with

PH
3170PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3171 function verify_get_ident() calls ip_connect() to connect a socket, but
3172 if the "connect()" function timed out, ip_connect() used to close the
3173 socket. However, verify_get_ident() also closes the socket later, and in
3174 between Exim writes to the log, which may get opened at this point. When
3175 the socket was closed in ip_connect(), the log could get the same file
3176 descriptor number as the socket. This naturally causes chaos. The fix is
3177 not to close the socket in ip_connect(); the socket should be closed by
3178 the function that creates it. There was only one place in the code where
3179 this was missing, in the iplookup router, which I don't think anybody now
3180 uses, but I've fixed it anyway.

3194
3195 (2) Add control=submission to the relay_from_hosts and authenticated
3196 clients checks, on the grounds that messages accepted by these
3197 statements are most likely to be submissions.

PH
3199PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3200
3201 (1) Generate an error if the third argument for the ${prvs expansion is
3202 not a single digit.
3203
3204 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3205 string.
3206
3207 (3) Reset the variables that are obtained from the first argument of
3208 ${prvscheck and used in the second argument before leaving the code,
3209 because their memory is reclaimed, so using them afterwards may do
3210 silly things.
3211
3212 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3213 one (it's much easier than Tom thought :-).
3214
3215 (5) Because of (4), we can now allow for the use of $prvscheck_result
3216 inside the third argument.

PH
3225PH/05 When a filter generated an autoreply, the entire To: header line was
3226 quoted in the delivery log line, like this:
3227
3228 => >A.N.Other <ano@some.domain> <original@ddress> ...
3229
3230 This has been changed so that it extracts the operative address. There
3231 may be more than one such address. If so, they are comma-separated, like
3232 this:
3233
3234 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
3236PH/06 When a client host used a correct literal IP address in a HELO or EHLO
3237 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3238 not being looked up in the rDNS to get a host name, Exim was showing the
3239 IP address twice in Received: lines, even though the IP addresses were
3240 identical. For example:
3241
3242 Received: from [1.2.3.4] (helo=[1.2.3.4])
3243
3244 However, if the real host name was known, it was omitting the HELO data
3245 if it matched the actual IP address. This has been tidied up so that it
3246 doesn't show the same IP address twice.

3248PH/07 When both +timestamp and +memory debugging was on, the value given by
3249 $tod_xxx expansions could be wrong, because the tod_stamp() function was
3250 called by the debug printing, thereby overwriting the timestamp buffer.
3251 Debugging no longer uses the tod_stamp() function when +timestamp is set.

3253PH/08 When the original message was included in an autoreply transport, it

3256 message.

3272PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

PH
3279 also a typo: it was using "Auto_submitted" (underscore instead of
3280 hyphen). Since every message generated by Exim is necessarily in response
