8Exim version 4.90
9-----------------
10
11JH/01 Rework error string handling in TLS interface so that the caller in
12 more cases is responsible for logging. This permits library-sourced
13 string to be attached to addresses during delivery, and collapses
14 pairs of long lines into single ones.
15

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

JH
19JH/02 Rework error string handling in DKIM to pass more info back to callers.
20 This permits better logging.
21
875512a3
JH
22JH/03 Rework the transport continued-connection mechanism: when TLS is active,
23 do not close it down and have the child transport start it up again on
24 the passed-on TCP connection. Instead, proxy the child (and any
25 subsequent ones) for TLS via a unix-domain socket channel. Logging is
26 affected: the continued delivery log lines do not have any DNSSEC, TLS
5013d912 27 Certificate or OCSP information. TLS cipher information is still logged.

29JH/04 Shorten the log line for daemon startup by collapsing adjacent sets of
30 identical IP addresses on different listening ports. Will also affect
31 "exiwhat" output.

34 add noisy ifdef guards to special-case this sillyness.
35 Patch from Bernd Kuhls.

37JH/05 Tighten up the checking in isip4 (et al): dotted-quad components larger
38 than 255 are no longer allowed.
39
7006ee24
JH
40JH/06 Default openssl_options to include +no_ticket, to reduce load on peers.
41 Disable the session-cache too, which might reduce our load. Since we
42 currrectly use a new context for every connection, both as server and
43 client, there is no benefit for these.
44 GnuTLS appears to not support tickets server-side by default (we don't
45 call gnutls_session_ticket_enable_server()) but client side is enabled
46 by default on recent versions (3.1.3 +) unless the PFS priority string
47 is used (3.2.4 +).

JH
71JH/04 Bug 2004: fix CHUNKING in non-PIPELINEING mode. Chunk data following
72 close after a BDAT command line could be taken as a following command,
73 giving a synch failure. Fix by only checking for synch immediately
74 before acknowledging the chunk.

80JH/05 Have the EHLO response advertise VRFY, if there is a vrfy ACL defined.
81 Previously we did not; the RFC seems ambiguous and VRFY is not listed
82 by IANA as a service extension. However, John Klensin suggests that we
83 should.
84
85JH/06 Bug 2017: Fix DKIM verification in -bh test mode. The data feed into

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

bd8fbe36 89JH/07 Rationalise the coding for callout smtp conversations and transport ones.
902fbd69
JH
90 As a side-benfit, callouts can now use PIPELINING hence fewer round-trips.
91
bd8fbe36
JH
92JH/08 Bug 2016: Fix DKIM verification vs. CHUNKING. Any BDAT commands after
93 the first were themselves being wrongly included in the feed into dkim
94 processing; with most chunk sizes in use this resulted in an incorrect
95 body hash calculated value.
96

97JH/09 Bug 2014: permit inclusion of a DKIM-Signature header in a received
98 DKIM signature block, for verification. Although advised against by
99 standards it is specifically not ruled illegal.

102
103JH/11 Bug 2029: Fix crash in DKIM verification when a message signature block is
104 missing a body hash (the bh= tag).
105
106JH/12 Bug 2018: Re-order Proxy Protocol startup versus TLS-on-connect startup.
107 It seems that HAProxy sends the Proxy Protocol information in clear and
108 only then does a TLS startup, so do the same.
109
110JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
111 TCP connections (such as for Spamd) unless the daemon successfully set
112 Fast Open mode on its listening sockets. This fixes breakage seen on
113 too-old kernels or those not configured for Fast Open, at the cost of
114 requiring both directions being enabled for TFO, and TFO never being used
115 by non-daemon-related Exim processes.
116
117JH/14 Bug 2000: Reject messages recieved with CHUNKING but with malformed line
118 endings, at least on the first header line. Try to canonify any that get
119 past that check, despite the cost.
120

JH
121JH/15 Angle-bracket nesting (an error inserted by broken sendmails) levels are
122 now limited to an arbitrary five deep, while parsing addresses with the
123 strip_excess_angle_brackets option enabled.

125PP/03 Bug 2018: For Proxy Protocol and TLS-on-connect, do not over-read and
126 instead leave the unprompted TLS handshake in socket buffer for the
127 TLS library to consume.

132
90341c71
JH
133JH/16 Drop variables when they go out of scope. Memory management drops a whole
134 region in one operation, for speed, and this leaves assigned pointers
135 dangling. Add checks run only under the testsuite which checks all
136 variables at a store-reset and panics on a dangling pointer; add code
137 explicitly nulling out all the variables discovered. Fixes one known
138 bug: a transport crash, where a dangling pointer for $sending_ip_address
139 originally assigned in a verify callout, is re-used.
140
1ec2ab36
PP
141PP/06 Drop '.' from @INC in various Perl scripts.
142
143PP/07 Switch FreeBSD iconv to always use the base-system libc functions.
144
145PP/08 Reduce a number of compilation warnings under clang; building with
146 CC=clang CFLAGS+=-Wno-dangling-else -Wno-logical-op-parentheses
147 should be warning-free.
148

152 realloc(NULL) is not equivalent to malloc() [SunOS et al].

JH
169JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
170 supports it and a size is available (ie. the sending peer gave us one).
8d042305 171
03d5892b
JH
172JH/02 The obsolete acl condition "demime" is removed (finally, after ten
173 years of being deprecated). The replacements are the ACLs
174 acl_smtp_mime and acl_not_smtp_mime.
175
4b0fe319
JH
176JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
177 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
178 or even an in-clear connection were permitted. Now, if the host lookup
179 was dnssec and dane was requested then the host is only used if the
180 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
181 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
182 if one fails this test.
183 This means that a poorly-configured remote DNS will make it incommunicado;
184 but it protects against a DNS-interception attack on it.

JH
206JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
207 a cutthrough deliver is pending, as we always want to make a connection.
208 This also avoids re-routing the message when later placing the cutthrough
209 connection after a verify cache hit.
210 Do not update it with the verify result either.
211
212JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
213 when routing results in more than one destination address.
214
ae8386f0
JH
215JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
216 signing (which inhibits the cutthrough capability). Previously only
217 the presence of an option was tested; now an expansion evaluating as
218 empty is permissible (obviously it should depend only on data available
219 when the cutthrough connection is made).

400 in transport context, after the attempt, and per-recipient. The latter type
401 is per host attempted. The event data is the error message, and the errno
402 information encodes the lookup type (A vs. MX) used for the (first) host,

998TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
999
1000 When a queue runner is handling a message, Exim first routes the
1001 recipient addresses, during which it prunes them based on the retry
1002 hints database. After that it attempts to deliver the message to
1003 any remaining recipients. It then updates the hints database using
1004 the retry rules.
1005
1006 So if a recipient address works intermittently, it can get repeatedly
1007 deferred at routing time. The retry hints record remains fresh so the
1008 address never reaches the final cutoff time.
1009
1010 This is a fairly common occurrence when a user is bumping up against
1011 their storage quota. Exim had some logic in its local delivery code
1012 to deal with this. However it did not apply to per-recipient defers
1013 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1014
1ddeb334
TF
1015 This change adds a proper retry rule check during routing so that the
1016 final cutoff time is checked against the message's age. We only do
1017 this check if there is an address retry record and there is not a
1018 domain retry record; this implies that previous attempts to handle
1019 the address had the retry_use_local_parts option turned on. We use
1020 this as an approximation for the destination being like a local
1021 delivery, as in LMTP.
67bd1ab3
TF
1022
1023 I suspect this new check makes the old local delivery cutoff check
1024 redundant, but I have not verified this so I left the code in place.

1033 the header to contain my full name, whereas it should have added
1034 a Resent-Sender: header. It erroneously treats any prefix of the

1346TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1347 lock up or crash if it happened to be inside a call to libc when it
1348 got a SIGUSR1 from exiwhat.
1349
1350 The SIGUSR1 handler appends the current process status to the process
1351 log which is later printed by exiwhat. It used to use the general
1352 purpose logging code to do this, but several functions it calls are
1353 not safe for signals.
1354
1355 The new output code in the SIGUSR1 handler is specific to the process
1356 log, and simple enough that it's easy to inspect for signal safety.
1357 Removing some special cases also simplifies the general logging code.
1358 Removing the spurious timestamps from the process log simplifies
1359 exiwhat.
1360
c99ce5c9
TF
1361TF/04 Improved ratelimit ACL condition.
1362
1363 The /noupdate option has been deprecated in favour of /readonly which
1364 has clearer semantics. The /leaky, /strict, and /readonly update modes
1365 are mutually exclusive. The update mode is no longer included in the
1366 database key; it just determines when the database is updated. (This
4c04137d 1367 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1368
1369 Exim now checks that the per_* options are used with an update mode that
1370 makes sense for the current ACL. For example, when Exim is processing a
1371 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1372 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1373 must specify per_mail/readonly. If you omit the update mode it defaults to
1374 /leaky where that makes sense (as before) or /readonly where required.
1375
1376 The /noupdate option is now undocumented but still supported for
1377 backwards compatibility. It is equivalent to /readonly except that in
1378 ACLs where /readonly is required you may specify /leaky/noupdate or
1379 /strict/noupdate which are treated the same as /readonly.
1380
1381 A useful new feature is the /count= option. This is a generalization
1382 of the per_byte option, so that you can measure the throughput of other
1383 aggregate values. For example, the per_byte option is now equivalent
1384 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1385
1386 The per_rcpt option has been generalized using the /count= mechanism
1387 (though it's more complicated than the per_byte equivalence). When it is
1388 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1389 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1390 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1391 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1392 Note that using per_rcpt with a non-readonly update mode in more than
1393 one ACL will cause the recipients to be double-counted. (The per_mail
1394 and per_byte options don't have this problem.)
1395
1396 The handling of very low rates has changed slightly. If the computed rate
1397 is less than the event's count (usually one) then this event is the first
1398 after a long gap. In this case the rate is set to the same as this event's
1399 count, so that the first message of a spam run is counted properly.
1400
1401 The major new feature is a mechanism for counting the rate of unique
1402 events. The new per_addr option counts the number of different
1403 recipients that someone has sent messages to in the last time period. It
1404 behaves like per_rcpt if all the recipient addresses are different, but
1405 duplicate recipient addresses do not increase the measured rate. Like
1406 the /count= option this is a general mechanism, so the per_addr option
1407 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1408 example, measure the rate that a client uses different sender addresses
1409 with the options per_mail/unique=$sender_address. There are further
1410 details in the main documentation.

1982PH/01 Another patch from the Sieve maintainer.
1983
6a3bceb1
PH
1984PH/02 When an IPv6 address is converted to a string for single-key lookup
1985 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1986 dots are used instead of colons so that keys in lsearch files need not
1987 contain colons. This was done some time before quoting was made available
1988 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1989 (notated using the quote facility) so as to distinguish them from IPv4
1990 keys. This meant that lookups for IP addresses in host lists did not work
1991 for iplsearch lookups.
1992
1993 This has been fixed by arranging for IPv6 addresses to be expressed with
1994 colons if the lookup type is iplsearch. This is not incompatible, because
1995 previously such lookups could never work.
1996
4c04137d 1997 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
1998 ordinary lsearch keys. However, making the change in all cases is
1999 incompatible and would probably break a number of configurations.

2004MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2005 conversion specification without a maximum field width, thereby enabling
2006 a rogue spamd server to cause a buffer overflow. While nobody in their
2007 right mind would setup Exim to query an untrusted spamd server, an
2008 attacker that gains access to a server running spamd could potentially
2009 exploit this vulnerability to run arbitrary code as the Exim user.

MH
2014MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2015 a directory entry by the name of the lookup key. Previously, if a
2016 symlink pointed to a non-existing file or a file in a directory that
2017 Exim lacked permissions to read, a lookup for a key matching that
2018 symlink would fail. Now it is enough that a matching directory entry

2202PH/29 SMTP synchronization checks are implemented when a command is read -
2203 there is a check that no more input is waiting when there shouldn't be

2205 some time before the response is written. In this time, more input might
2206 arrive, invalidly. So now there are extra checks after an ACL has run for
2207 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2208 pipelining has not been advertised.

2223 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
2224 was a macro that became an assignment, so it seemed to work. This has

PH
2282 the response to the final '.' that terminates a message, but only in the
2283 case where the client has not sent further data following the '.'
2284 (unfortunately, this is allowed). However, in many cases there won't be
2285 any further data because there won't be any more messages to send. A call
2286 to select() can be used: if it shows that the input is "ready", there is
2287 either input waiting, or the socket has been closed. An attempt to read
2288 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2289 would have sent an OK response which the client would never have see.

2301 fixed by 4.65/MH/01 (is this a record?) are fixed:
2302
2303 (i) An empty string was always treated as zero by the numeric comparison
2304 operators. This behaviour has been restored.
2305
2306 (ii) It is documented that the numeric comparison operators always treat
2307 their arguments as decimal numbers. This was broken in that numbers
2308 starting with 0 were being interpreted as octal.

2310 While fixing these problems I realized that there was another issue that
2311 hadn't been noticed. Values of message_size_limit (both the global option
2312 and the transport option) were treated as octal if they started with 0.
2313 The documentation was vague. These values are now always treated as
2314 decimal, and I will make that clear in the documentation.

2331 large number of recipients for a single message is ridiculous
2332 (performance will be very, very poor), I have chosen to impose a limit

2339TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2340 leftover -K file (the existence of which was triggered by #402).

2343 these files.

2349TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

2356 in the field name.

PH
2358PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2359 callout verification, Exim cached a "reject" for the entire domain. This
2360 is correct for most verifications, but it is not correct for a recipient
2361 verification with use_sender or use_postmaster set, because in that case
2362 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2363 case of MAIL FROM:<> rejection from other early rejections (e.g.
2364 rejection of HELO). When verifying a recipient using a non-null MAIL
2365 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2366 Whatever the result of the callout, the value of the domain cache is
2367 left unchanged (for any other kind of callout, getting as far as trying
2368 RCPT means that the domain itself is ok).

2402PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2404 probably the interface on which it is arriving) and not to the outgoing
2405 callout (which could be using a different interface). This has been
2406 changed to use the value of the helo_data option from the smtp transport
2407 instead - this is what is used when a message is actually being sent. If
2408 there is no remote transport (possible with a router that sets up host
2409 addresses), $smtp_active_hostname is used.

7befa435 2412 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2413 (a) The code assumed that strncpy() returns a negative number on buffer
2414 overflow, which isn't the case. Replaced with Exim's string_format()
2415 function.
2416 (b) There were several signed/unsigned issues. I just did the minimum
2417 hacking in of casts. There is scope for a larger refactoring.
2418 (c) The code used strcasecmp() which is not a standard C function.
2419 Replaced with Exim's strcmpic() function.
2420 (d) The code set only $1; it now sets $auth1 as well.
2421 (e) A simple test gave the error "authentication client didn't specify
2422 service in request". It would seem that Dovecot has changed its
2423 interface. Fortunately there's a specification; I followed it and
2424 changed what the client sends and it appears to be working now.

2429PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2430 address A is aliased to B and C, where B exists and C does not. Without
2431 -v the output is "A verified" because verification stops after a
2432 successful redirection if more than one address is generated. However,
2433 with -v the child addresses are also verified. Exim was outputting "A
2434 failed to verify" and then showing the successful verification for C,
2435 with its parentage. It now outputs "B failed to verify", showing B's
2436 parentage before showing the successful verification of C.

2441
322050c2
PH
2442PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2443 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2444 they consult the DNS. I had assumed they would set it the way they
2445 wanted; and indeed my experiments on Linux seem to show that in some
2446 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2447 To be on the safe side, however, I have now made the interface to
2448 host_find_byname() similar to host_find_bydns(), with an argument
2449 containing the DNS resolver options. The host_find_byname() function now
2450 sets these options at its start, just as host_find_bydns() does. The smtp
2451 transport options dns_qualify_single and dns_search_parents are passed to
2452 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2453 of host_find_byname() use the default settings of RES_DEFNAMES
2454 (qualify_single) but not RES_DNSRCH (search_parents).

2456PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2457 spool_read_header() do less string testing, by means of a preliminary
2458 switch on the second character of optional "-foo" lines. (This is
2459 overdue, caused by the large number of possibilities that now exist.
2460 Originally there were few.) While I was there, I also converted the
2461 str(n)cmp tests so they don't re-test the leading "-" and the first
2462 character, in the hope this might squeeze out yet more improvement.

PH
2464PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2465 flag allowing group syntax was set by the header_syntax check but not
2466 turned off, possible causing trouble later; (2) The flag was not being
2467 set at all for the header_verify test, causing "group"-style headers to
2468 be rejected. I have now set it in this case, and also caused header_
2469 verify to ignore an empty address taken from a group. While doing this, I
2470 came across some other cases where the code for allowing group syntax
2471 while scanning a header line wasn't quite right (mostly, not resetting
2472 the flag correctly in the right place). These bugs could have caused
2473 trouble for malformed header lines. I hope it is now all correct.

PH
2475PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2476 with the "reply" argument non-NULL. The code, however (which originally
2477 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2478 but it didn't always do it. This confused somebody who was copying the
2479 code for some other use. I have removed all the tests.

PH
2481PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2482 feature that was used to support insecure browsers during the U.S. crypto
2483 embargo. It requires special client support, and Exim is probably the
2484 only MTA that supported it -- and would never use it because real RSA is
2485 always available. This code has been removed, because it had the bad
2486 effect of slowing Exim down by computing (never used) parameters for the
2487 RSA_EXPORT functionality.

2492 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2493 if the connection is using TLS or if the remote IP is the same as the
2494 local IP, and the "valid-client-cert option" if a client certificate has
2495 been verified.

2526
2527PH/30 Exim was sometimes attempting to deliver messages that had suffered
2528 address errors (4xx response to RCPT) over the same connection as other
2529 messages routed to the same hosts. Such deliveries are always "forced",
2530 so retry times are not inspected. This resulted in far too many retries
2531 for the affected addresses. The effect occurred only when there were more
2532 hosts than the hosts_max_try setting in the smtp transport when it had
2533 the 4xx errors. Those hosts that it had tried were not added to the list
2534 of hosts for which the message was waiting, so if all were tried, there
2535 was no problem. Two fixes have been applied:
2536
2537 (i) If there are any address or message errors in an SMTP delivery, none
2538 of the hosts (tried or untried) are now added to the list of hosts
2539 for which the message is waiting, so the message should not be a
2540 candidate for sending over the same connection that was used for a
2541 successful delivery of some other message. This seems entirely
2542 reasonable: after all the message is NOT "waiting for some host".
2543 This is so "obvious" that I'm not sure why it wasn't done
2544 previously. Hope I haven't missed anything, but it can't do any
2545 harm, as the worst effect is to miss an optimization.
2546
2547 (ii) If, despite (i), such a delivery is accidentally attempted, the
2548 routing retry time is respected, so at least it doesn't keep
2549 hammering the server.

2565 written to the panic log as well as the main log, but it isn't really

2567 removed the panic log writing for the ECONNRESET error when getsockname()
2568 fails.

48c7f9e2
PH
2570PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2571 runs only) independently of the message's sender address. This meant
2572 that, if the 4xx error was in fact related to the sender, a different
2573 message to the same recipient with a different sender could confuse
4c04137d 2574 things. In particular, this can happen when sending to a greylisting
48c7f9e2

2575 server, but other circumstances could also provoke similar problems.
2576 I have changed the default so that the retry time for these errors is now
2577 based a combination of the sender and recipient addresses. This change
2578 can be overridden by setting address_retry_include_sender=false in the
2579 smtp transport.

2849 Unfortunately, if there is a major crisis, such as a disk failure,
2850 tcp-wrappers gives "deny", whereas what one would like would be some
2851 kind of temporary error. A kludge has been added to help with this.
2852 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2853 554 error is used if errno is still zero or contains ENOENT (which occurs
2854 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2855 451 error is used.

2891PH/01 The code for finding all the local interface addresses on a FreeBSD
2892 system running IPv6 was broken. This may well have applied to all BSD
2893 systems, as well as to others that have similar system calls. The broken
2894 code found IPv4 interfaces correctly, but gave incorrect values for the
2895 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2896 that it would not match correctly against @[] and not recognize the IPv6
2897 addresses as local.

2940 autoreply, Exim could try to deliver to a non-existent relative file
2941 name, causing unrelated and misleading errors. What now happens is that

2975 additional section of a DNS packet that returns MX or SRV records.
2976 Instead, it always explicitly searches for A/AAAA records. This avoids
2977 major problems that occur when a DNS server includes only records of one
2978 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2979 fixed another bug: if SRV records were looked up and the corresponding
2980 address records were *not* found in the additional section, the port
2981 values from the SRV records were lost.

2983PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2991PH/19 When calculating a retry time, Exim used to measure the "time since
2992 failure" by looking at the "first failed" field in the retry record. Now
2993 it does not use this if it is later than than the arrival time of the
2994 message. Instead it uses the arrival time. This makes for better
2995 behaviour in cases where some deliveries succeed, thus re-setting the
2996 "first failed" field. An example is a quota failure for a huge message
2997 when small messages continue to be delivered. Without this change, the
2998 "time since failure" will always be short, possible causing more frequent
2999 delivery attempts for the huge message than are intended.

3081JJ/03 exipick: Removed parentheses from 'next' and 'last' calls that specified
3082 a label. They prevented compilation on older perls.
3083
3084JJ/04 exipick: Refactored code to prevent implicit split to @_ which caused
3085 a warning to be raised on newish perls.
3086
3087JJ/05 exipick: Fixed bug where -bpc always showed a count of all messages
3088 on queue. Changes to match documented behaviour of showing count of
3089 messages matching specified criteria.

3096PH/42 The content-scanning code uses fopen() to create files in which to put
3097 message data. Previously it was not paying any attention to the mode of
3098 the files. Exim runs with umask(0) because the rest of the code creates
3099 files with open(), and sets the required mode explicitly. Thus, these
3100 files were ending up world-writeable. This was not a big issue, because,
3101 being within the spool directory, they were not world-accessible. I have
3102 created a function called modefopen, which takes an additional mode
3103 argument. It sets umask(777), creates the file, chmods it to the required
3104 mode, then resets the umask. All the relevant calls to fopen() in the
3105 content scanning code have been changed to use this function.

3107PH/43 If retry_interval_max is set greater than 24 hours, it is quietly reset
3108 to 24 hours. This avoids potential overflow problems when processing G
3109 and H retry rules. I suspect nobody ever tinkers with this value.

PH
3113PH/45 When the plaintext authenticator is running as a client, the server's
3114 challenges are checked to ensure they are valid base64 strings. By
3115 default, the authentication attempt is cancelled if an invalid string is
3116 received. Setting client_ignore_invalid_base64 true ignores these errors.
3117 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
3118 they are received. Thus, the responses can be made to depend on the
3119 challenges. If an invalid string is ignored, an empty string is placed in
3120 the variable.

PH
3131PH/50 When an Exim quota was set without a file count quota, and mailbox_size
3132 was also set, the appendfile transport was unnecessarily scanning a
3133 directory of message files (e.g. for maildir delivery) to find the count
3134 of files (along with the size), even though it did not need this
3135 information. It now does the scan only if it needs to find either the
3136 size of the count of files.

PH
3140PH/52 Two bugs concerned with error handling when the smtp transport is
3141 used in LMTP mode:
3142
3143 (i) Exim was not creating retry information for temporary errors given
3144 for individual recipients after the DATA command when the smtp transport
3145 was used in LMTP mode. This meant that they could be retried too
3146 frequently, and not timed out correctly.
3147
3148 (ii) Exim was setting the flag that allows error details to be returned
3149 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3150 recipients that were returned after the DATA command.
3151
3152PH/53 This is related to PH/52, but is more general: for any failing address,
3153 when detailed error information was permitted to be returned to the
3154 sender, but the error was temporary, then after the final timeout, only
3155 "retry timeout exceeded" was returned. Now it returns the full error as
3156 well as "retry timeout exceeded".

3180 SMTP output lines.

3194PH/62 When verifying, if an address was redirected to one new address, so that
3195 verification continued, and the new address failed or deferred after
3196 having set something in $address_data, the value of $address_data was not
3197 passed back to the ACL. This was different to the case when no
3198 redirection occurred. The value is now passed back in both cases.

PH
3200PH/63 Changed the macro HAVE_LOGIN_CAP (see PH/41 for this release above) to
3201 HAVE_SETCLASSRESOURCES because there are different APIs in use that all
3202 use login_cap.h, so on its own it isn't the distinguishing feature. The
3203 new name refers directly to the setclassresources() function.

PH
3212PH/68 The bounce_return_message and bounce_return_body options were not being
3213 honoured for bounces generated during the reception of non-SMTP messages.
3214 In particular, this applied to messages rejected by the ACL. This bug has
3215 been fixed. However, if bounce_return_message is true and bounce_return_
3216 body is false, the headers that are returned for a non-SMTP message
3217 include only those that have been read before the error was detected.
3218 (In the case of an ACL rejection, they have all been read.)

PH
3220PH/69 The HTML version of the specification is now built in a directory called
3221 spec_html instead of spec.html, because the latter looks like a path with

PH
3226PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3227 function verify_get_ident() calls ip_connect() to connect a socket, but
3228 if the "connect()" function timed out, ip_connect() used to close the
3229 socket. However, verify_get_ident() also closes the socket later, and in
3230 between Exim writes to the log, which may get opened at this point. When
3231 the socket was closed in ip_connect(), the log could get the same file
3232 descriptor number as the socket. This naturally causes chaos. The fix is
3233 not to close the socket in ip_connect(); the socket should be closed by
3234 the function that creates it. There was only one place in the code where
3235 this was missing, in the iplookup router, which I don't think anybody now
3236 uses, but I've fixed it anyway.

3238PH/72 Make dns_again_means_nonexist apply to lookups using gethostbyname() as

3246PH/01 Two changes to the default runtime configuration:

3248 (1) Move the checks for relay_from_hosts and authenticated clients from
3249 after to before the (commented out) DNS black list checks.
3250
3251 (2) Add control=submission to the relay_from_hosts and authenticated
3252 clients checks, on the grounds that messages accepted by these
3253 statements are most likely to be submissions.

PH
3255PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3256
3257 (1) Generate an error if the third argument for the ${prvs expansion is
3258 not a single digit.
3259
3260 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3261 string.
3262
3263 (3) Reset the variables that are obtained from the first argument of
3264 ${prvscheck and used in the second argument before leaving the code,
3265 because their memory is reclaimed, so using them afterwards may do
3266 silly things.
3267
3268 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3269 one (it's much easier than Tom thought :-).
3270
3271 (5) Because of (4), we can now allow for the use of $prvscheck_result
3272 inside the third argument.
