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.

33PP/02 Bug 2070: uClibc defines __GLIBC__ without providing glibc headers;
34 add noisy ifdef guards to special-case this sillyness.
35 Patch from Bernd Kuhls.
36

JH
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 +).

49PP/03 Add $SOURCE_DATE_EPOCH support for reproducible builds, per spec at
50 <https://reproducible-builds.org/specs/source-date-epoch/>.
51
4c2471ca
JH
52JH/07 Fix smtp transport use of limited max_rcpt under mua_wrapper. Previously
53 the check for any unsuccessful recipients did not notice the limit, and
54 erroneously found still-pending ones.
55
4e910c01
JH
56JH/08 Pipeline CHUNKING command and data together, on kernels that support
57 MSG_MORE. Only in-clear (not on TLS connections).
58
42055a33
JH
59JH/09 Avoid using a temporary file during transport using dkim. Unless a
60 transport-filter is involved we can buffer the headers in memory for
61 creating the signature, and read the spool data file once for the
62 signature and again for transmission.
63
eeb35890
JH
64JH/10 Enable use of sendfile in Linux builds as default. It was disabled in
65 4.77 as the kernel support then wasn't solid, having issues in 64bit
7d758a6a 66 mode. Now, it's been long enough. Add support for FreeBSD also.

JH
68JH/11 Bug 2104: Fix continued use of a transport connection with TLS. In the
69 case where the routing stage had gathered several addresses to send to
70 a host before calling the transport for the first, we previously failed
71 to close down TLS in the old transport process before passing the TCP
72 connection to the new process. The new one sent a STARTTLS command
73 which naturally failed, giving a failed delivery and bloating the retry
74 database. Investigation and fix prototype from Wolfgang Breyha.
75
40525d07
JH
76JH/12 Fix check on SMTP command input synchronisation. Previously there were
77 false-negatives in the check that the sender had not preempted a response
78 or prompt from Exim (running as a server), due to that code's lack of
a5ffa9b4 79 awareness of the SMTP input buffering.
40525d07 80
f33875c3
PP
81PP/04 Add commandline_checks_require_admin option.
82 Exim drops privileges sanely, various checks such as -be aren't a
83 security problem, as long as you trust local users with access to their
84 own account. When invoked by services which pass untrusted data to
85 Exim, this might be an issue. Set this option in main configuration
86 AND make fixes to the calling application, such as using `--` to stop
87 processing options.
88
a5ffa9b4
JH
89JH/13 Do pipelining under TLS. Previously, although safe, no advantage was
90 taken. Now take care to pack both (client) MAIL,RCPT,DATA, and (server)
91 responses to those, into a single TLS record each way (this usually means
92 a single packet). As a side issue, smtp_enforce_sync now works on TLS
93 connections.

PP
95PP/05 OpenSSL/1.1: use DH_bits() for more accurate DH param sizes. This
96 affects you only if you're dancing at the edge of the param size limits.
97 If you are, and this message makes sense to you, then: raise the
98 configured limit or use OpenSSL 1.1. Nothing we can do for older
99 versions.

142JH/05 Have the EHLO response advertise VRFY, if there is a vrfy ACL defined.

167
168JH/12 Bug 2018: Re-order Proxy Protocol startup versus TLS-on-connect startup.
169 It seems that HAProxy sends the Proxy Protocol information in clear and
170 only then does a TLS startup, so do the same.
171
172JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
173 TCP connections (such as for Spamd) unless the daemon successfully set
174 Fast Open mode on its listening sockets. This fixes breakage seen on
175 too-old kernels or those not configured for Fast Open, at the cost of
176 requiring both directions being enabled for TFO, and TFO never being used
177 by non-daemon-related Exim processes.
178
179JH/14 Bug 2000: Reject messages recieved with CHUNKING but with malformed line
180 endings, at least on the first header line. Try to canonify any that get
181 past that check, despite the cost.

195JH/16 Drop variables when they go out of scope. Memory management drops a whole

197 dangling. Add checks run only under the testsuite which checks all
198 variables at a store-reset and panics on a dangling pointer; add code
199 explicitly nulling out all the variables discovered. Fixes one known
200 bug: a transport crash, where a dangling pointer for $sending_ip_address
201 originally assigned in a verify callout, is re-used.

JH
238JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
239 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
240 or even an in-clear connection were permitted. Now, if the host lookup
241 was dnssec and dane was requested then the host is only used if the
242 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
243 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
244 if one fails this test.
245 This means that a poorly-configured remote DNS will make it incommunicado;
246 but it protects against a DNS-interception attack on it.

268JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
269 a cutthrough deliver is pending, as we always want to make a connection.
270 This also avoids re-routing the message when later placing the cutthrough
271 connection after a verify cache hit.

808
809 When a message was received over SMTP with TLS, Exim failed to clear up
810 the incoming connection properly after forking off the child process to
811 deliver the message. In some situations the subsequent outgoing
812 delivery connection happened to have the same fd number as the incoming
813 connection previously had. Exim would try to use TLS and fail, logging
814 a "Bad file descriptor" error.

1060TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
1061
1062 When a queue runner is handling a message, Exim first routes the
1063 recipient addresses, during which it prunes them based on the retry
1064 hints database. After that it attempts to deliver the message to
1065 any remaining recipients. It then updates the hints database using
1066 the retry rules.
1067
1068 So if a recipient address works intermittently, it can get repeatedly
1069 deferred at routing time. The retry hints record remains fresh so the
1070 address never reaches the final cutoff time.
1071
1072 This is a fairly common occurrence when a user is bumping up against
1073 their storage quota. Exim had some logic in its local delivery code
1074 to deal with this. However it did not apply to per-recipient defers
1075 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1076
1ddeb334
TF
1077 This change adds a proper retry rule check during routing so that the
1078 final cutoff time is checked against the message's age. We only do
1079 this check if there is an address retry record and there is not a
1080 domain retry record; this implies that previous attempts to handle
1081 the address had the retry_use_local_parts option turned on. We use
1082 this as an approximation for the destination being like a local
1083 delivery, as in LMTP.
67bd1ab3
TF
1084
1085 I suspect this new check makes the old local delivery cutoff check
1086 redundant, but I have not verified this so I left the code in place.

1408TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1409 lock up or crash if it happened to be inside a call to libc when it
1410 got a SIGUSR1 from exiwhat.
1411
1412 The SIGUSR1 handler appends the current process status to the process
1413 log which is later printed by exiwhat. It used to use the general
1414 purpose logging code to do this, but several functions it calls are
1415 not safe for signals.
1416
1417 The new output code in the SIGUSR1 handler is specific to the process
1418 log, and simple enough that it's easy to inspect for signal safety.
1419 Removing some special cases also simplifies the general logging code.
1420 Removing the spurious timestamps from the process log simplifies
1421 exiwhat.
1422

TF
1423TF/04 Improved ratelimit ACL condition.
1424
1425 The /noupdate option has been deprecated in favour of /readonly which
1426 has clearer semantics. The /leaky, /strict, and /readonly update modes
1427 are mutually exclusive. The update mode is no longer included in the
1428 database key; it just determines when the database is updated. (This
4c04137d 1429 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1430
1431 Exim now checks that the per_* options are used with an update mode that
1432 makes sense for the current ACL. For example, when Exim is processing a
1433 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1434 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1435 must specify per_mail/readonly. If you omit the update mode it defaults to
1436 /leaky where that makes sense (as before) or /readonly where required.
1437
1438 The /noupdate option is now undocumented but still supported for
1439 backwards compatibility. It is equivalent to /readonly except that in
1440 ACLs where /readonly is required you may specify /leaky/noupdate or
1441 /strict/noupdate which are treated the same as /readonly.
1442
1443 A useful new feature is the /count= option. This is a generalization
1444 of the per_byte option, so that you can measure the throughput of other
1445 aggregate values. For example, the per_byte option is now equivalent
1446 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1447
1448 The per_rcpt option has been generalized using the /count= mechanism
1449 (though it's more complicated than the per_byte equivalence). When it is
1450 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1451 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1452 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1453 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1454 Note that using per_rcpt with a non-readonly update mode in more than
1455 one ACL will cause the recipients to be double-counted. (The per_mail
1456 and per_byte options don't have this problem.)
1457
1458 The handling of very low rates has changed slightly. If the computed rate
1459 is less than the event's count (usually one) then this event is the first
1460 after a long gap. In this case the rate is set to the same as this event's
1461 count, so that the first message of a spam run is counted properly.
1462
1463 The major new feature is a mechanism for counting the rate of unique
1464 events. The new per_addr option counts the number of different
1465 recipients that someone has sent messages to in the last time period. It
1466 behaves like per_rcpt if all the recipient addresses are different, but
1467 duplicate recipient addresses do not increase the measured rate. Like
1468 the /count= option this is a general mechanism, so the per_addr option
1469 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1470 example, measure the rate that a client uses different sender addresses
1471 with the options per_mail/unique=$sender_address. There are further
1472 details in the main documentation.

2022 Note to Michael Haardt: I had to rename some vars in sieve.c. They
2023 were called 'true' and it seems that C99 defines that as a reserved

2042-----------------
2043
2044PH/01 Another patch from the Sieve maintainer.
2045
6a3bceb1
PH
2046PH/02 When an IPv6 address is converted to a string for single-key lookup
2047 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
2048 dots are used instead of colons so that keys in lsearch files need not
2049 contain colons. This was done some time before quoting was made available
2050 in lsearch files. However, iplsearch files do require colons in IPv6 keys
2051 (notated using the quote facility) so as to distinguish them from IPv4
2052 keys. This meant that lookups for IP addresses in host lists did not work
2053 for iplsearch lookups.
2054
2055 This has been fixed by arranging for IPv6 addresses to be expressed with
2056 colons if the lookup type is iplsearch. This is not incompatible, because
2057 previously such lookups could never work.
2058
4c04137d 2059 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2060 ordinary lsearch keys. However, making the change in all cases is
2061 incompatible and would probably break a number of configurations.
2062

2063TK/01 Change PRVS address formatting scheme to reflect latests BATV draft
2064 version.
2065
0806a9c5
MH
2066MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2067 conversion specification without a maximum field width, thereby enabling
2068 a rogue spamd server to cause a buffer overflow. While nobody in their
2069 right mind would setup Exim to query an untrusted spamd server, an
2070 attacker that gains access to a server running spamd could potentially
2071 exploit this vulnerability to run arbitrary code as the Exim user.

2073TK/02 Bugzilla 502: Apply patch to make the SPF-Received: header use

2075
0f2cbd1b
MH
2076MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2077 a directory entry by the name of the lookup key. Previously, if a
2078 symlink pointed to a non-existing file or a file in a directory that
2079 Exim lacked permissions to read, a lookup for a key matching that
2080 symlink would fail. Now it is enough that a matching directory entry
2081 exists, symlink or not. (Bugzilla 503.)

2154PH/02 In an ACL statement such as

2158 if a client was not listed at all, or was listed with a value other than
2159 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
2160 the condition was not true (as it should be), so access was not denied.

PH
2264PH/29 SMTP synchronization checks are implemented when a command is read -
2265 there is a check that no more input is waiting when there shouldn't be
2266 any. However, for some commands, a delay in an ACL can mean that it is
2267 some time before the response is written. In this time, more input might
2268 arrive, invalidly. So now there are extra checks after an ACL has run for
2269 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2270 pipelining has not been advertised.

PH
2282PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in

2285 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
2286 was a macro that became an assignment, so it seemed to work. This has
2287 changed to a proper function call with a void return, hence the compile
2288 error. Exim's code has been fixed.

2318 behaving confusingly. When first started, it used values for whoever
2319 started the daemon, but after a SIGHUP it used the Exim user (because it
2320 calls itself on a restart). I have changed the code so that it now always
2321 uses the Exim user.

2323PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a

2325 sender address), and a DATA command is nevertheless sent (as can happen
2326 with PIPELINING or a stupid MUA), the error message that was given to the
2327 RCPT commands is included in the rejection of the DATA command. This is
2328 intended to be helpful for MUAs that show only the final error to their

58eb016e 2343PH/44 I found a way to check for a TCP/IP connection going away before sending

PH
2344 the response to the final '.' that terminates a message, but only in the
2345 case where the client has not sent further data following the '.'
2346 (unfortunately, this is allowed). However, in many cases there won't be
2347 any further data because there won't be any more messages to send. A call
2348 to select() can be used: if it shows that the input is "ready", there is
2349 either input waiting, or the socket has been closed. An attempt to read
2350 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2351 would have sent an OK response which the client would never have see.

2360-----------------
2361
2362PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2363 fixed by 4.65/MH/01 (is this a record?) are fixed:
2364
2365 (i) An empty string was always treated as zero by the numeric comparison
2366 operators. This behaviour has been restored.
2367
2368 (ii) It is documented that the numeric comparison operators always treat
2369 their arguments as decimal numbers. This was broken in that numbers
2370 starting with 0 were being interpreted as octal.
2371
2372 While fixing these problems I realized that there was another issue that
2373 hadn't been noticed. Values of message_size_limit (both the global option
2374 and the transport option) were treated as octal if they started with 0.
2375 The documentation was vague. These values are now always treated as
2376 decimal, and I will make that clear in the documentation.

2392 is held in a short int, deliveries were likely to be lost. As such a
2393 large number of recipients for a single message is ridiculous
2394 (performance will be very, very poor), I have chosen to impose a limit
2395 rather than extend the field.

2401TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2402 leftover -K file (the existence of which was triggered by #402).

2411TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

PH
2420PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2421 callout verification, Exim cached a "reject" for the entire domain. This
2422 is correct for most verifications, but it is not correct for a recipient
2423 verification with use_sender or use_postmaster set, because in that case
2424 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2425 case of MAIL FROM:<> rejection from other early rejections (e.g.
2426 rejection of HELO). When verifying a recipient using a non-null MAIL
2427 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2428 Whatever the result of the callout, the value of the domain cache is
2429 left unchanged (for any other kind of callout, getting as far as trying
2430 RCPT means that the domain itself is ok).

2464PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2466 probably the interface on which it is arriving) and not to the outgoing
2467 callout (which could be using a different interface). This has been
2468 changed to use the value of the helo_data option from the smtp transport
2469 instead - this is what is used when a message is actually being sent. If
2470 there is no remote transport (possible with a router that sets up host
2471 addresses), $smtp_active_hostname is used.

14aa5a05
PH
2475 (a) The code assumed that strncpy() returns a negative number on buffer
2476 overflow, which isn't the case. Replaced with Exim's string_format()
2477 function.
2478 (b) There were several signed/unsigned issues. I just did the minimum
2479 hacking in of casts. There is scope for a larger refactoring.
2480 (c) The code used strcasecmp() which is not a standard C function.
2481 Replaced with Exim's strcmpic() function.
2482 (d) The code set only $1; it now sets $auth1 as well.
2483 (e) A simple test gave the error "authentication client didn't specify
2484 service in request". It would seem that Dovecot has changed its
2485 interface. Fortunately there's a specification; I followed it and
2486 changed what the client sends and it appears to be working now.

2492 address A is aliased to B and C, where B exists and C does not. Without
2493 -v the output is "A verified" because verification stops after a
2494 successful redirection if more than one address is generated. However,
2495 with -v the child addresses are also verified. Exim was outputting "A
2496 failed to verify" and then showing the successful verification for C,
2497 with its parentage. It now outputs "B failed to verify", showing B's
2498 parentage before showing the successful verification of C.

322050c2
PH
2504PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2505 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2506 they consult the DNS. I had assumed they would set it the way they
2507 wanted; and indeed my experiments on Linux seem to show that in some
2508 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2509 To be on the safe side, however, I have now made the interface to
2510 host_find_byname() similar to host_find_bydns(), with an argument
2511 containing the DNS resolver options. The host_find_byname() function now
2512 sets these options at its start, just as host_find_bydns() does. The smtp
2513 transport options dns_qualify_single and dns_search_parents are passed to
2514 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2515 of host_find_byname() use the default settings of RES_DEFNAMES
2516 (qualify_single) but not RES_DNSRCH (search_parents).

2519 spool_read_header() do less string testing, by means of a preliminary
2520 switch on the second character of optional "-foo" lines. (This is
2521 overdue, caused by the large number of possibilities that now exist.
2522 Originally there were few.) While I was there, I also converted the
2523 str(n)cmp tests so they don't re-test the leading "-" and the first
2524 character, in the hope this might squeeze out yet more improvement.

2526PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2527 flag allowing group syntax was set by the header_syntax check but not
2528 turned off, possible causing trouble later; (2) The flag was not being
2529 set at all for the header_verify test, causing "group"-style headers to
2530 be rejected. I have now set it in this case, and also caused header_
2531 verify to ignore an empty address taken from a group. While doing this, I
2532 came across some other cases where the code for allowing group syntax
2533 while scanning a header line wasn't quite right (mostly, not resetting
2534 the flag correctly in the right place). These bugs could have caused
2535 trouble for malformed header lines. I hope it is now all correct.

PH
2537PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

2539 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2540 but it didn't always do it. This confused somebody who was copying the
2541 code for some other use. I have removed all the tests.

PH
2543PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2544 feature that was used to support insecure browsers during the U.S. crypto
2545 embargo. It requires special client support, and Exim is probably the
2546 only MTA that supported it -- and would never use it because real RSA is
2547 always available. This code has been removed, because it had the bad
2548 effect of slowing Exim down by computing (never used) parameters for the
2549 RSA_EXPORT functionality.

2554 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2555 if the connection is using TLS or if the remote IP is the same as the
2556 local IP, and the "valid-client-cert option" if a client certificate has
2557 been verified.

2588
2589PH/30 Exim was sometimes attempting to deliver messages that had suffered
2590 address errors (4xx response to RCPT) over the same connection as other
2591 messages routed to the same hosts. Such deliveries are always "forced",
2592 so retry times are not inspected. This resulted in far too many retries
2593 for the affected addresses. The effect occurred only when there were more
2594 hosts than the hosts_max_try setting in the smtp transport when it had
2595 the 4xx errors. Those hosts that it had tried were not added to the list
2596 of hosts for which the message was waiting, so if all were tried, there
2597 was no problem. Two fixes have been applied:
2598
2599 (i) If there are any address or message errors in an SMTP delivery, none
2600 of the hosts (tried or untried) are now added to the list of hosts
2601 for which the message is waiting, so the message should not be a
2602 candidate for sending over the same connection that was used for a
2603 successful delivery of some other message. This seems entirely
2604 reasonable: after all the message is NOT "waiting for some host".
2605 This is so "obvious" that I'm not sure why it wasn't done
2606 previously. Hope I haven't missed anything, but it can't do any
2607 harm, as the worst effect is to miss an optimization.
2608
2609 (ii) If, despite (i), such a delivery is accidentally attempted, the
2610 routing retry time is respected, so at least it doesn't keep
2611 hammering the server.

48c7f9e2
PH
2632PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2633 runs only) independently of the message's sender address. This meant
2634 that, if the 4xx error was in fact related to the sender, a different
2635 message to the same recipient with a different sender could confuse
4c04137d 2636 things. In particular, this can happen when sending to a greylisting

2637 server, but other circumstances could also provoke similar problems.
2638 I have changed the default so that the retry time for these errors is now

2909PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
2910 "Deny" causes Exim to reject the incoming connection with a 554 error.
2911 Unfortunately, if there is a major crisis, such as a disk failure,
2912 tcp-wrappers gives "deny", whereas what one would like would be some
2913 kind of temporary error. A kludge has been added to help with this.
2914 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2915 554 error is used if errno is still zero or contains ENOENT (which occurs
2916 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2917 451 error is used.

2939PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
2940 folder from quota calculations, a direct delivery into this folder messed
2941 up the contents of the maildirsize file. This was because the regex was
2942 used only to exclude .Trash (or whatever) when the size of the mailbox
2943 was calculated. There was no check that a delivery was happening into an
2944 excluded directory. This bug has been fixed by ignoring all quota

2951-----------------
2952
2953PH/01 The code for finding all the local interface addresses on a FreeBSD
2954 system running IPv6 was broken. This may well have applied to all BSD
2955 systems, as well as to others that have similar system calls. The broken
2956 code found IPv4 interfaces correctly, but gave incorrect values for the
2957 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2958 that it would not match correctly against @[] and not recognize the IPv6
2959 addresses as local.

3000 syntactically invalid From: or Reply-to: line, and a filter used this to
3001 generate an autoreply, and therefore failed to obtain an address for the
3002 autoreply, Exim could try to deliver to a non-existent relative file
3003 name, causing unrelated and misleading errors. What now happens is that
3004 it logs this as a hard delivery error, but does not attempt to create a

3022 non-existent - all you got was a failure to exec. I have made two
3023 changes:

3025 (a) Failures to set uid/gid, the current directory, or a process leader
3026 in a subprocess such as that created by queryprogram now generate
4c04137d 3027 suitable debugging output when -d is set.
59e82a2a

3036PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
3037 additional section of a DNS packet that returns MX or SRV records.
3038 Instead, it always explicitly searches for A/AAAA records. This avoids
3039 major problems that occur when a DNS server includes only records of one
3040 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
3041 fixed another bug: if SRV records were looked up and the corresponding
3042 address records were *not* found in the additional section, the port
3043 values from the SRV records were lost.

ea49d0e1
PH
3045PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

064a94c9
PH
3049PH/18 If quota_warn_message contains a From: header, Exim now refrains from

3052
727071f8
PH
3053PH/19 When calculating a retry time, Exim used to measure the "time since
3054 failure" by looking at the "first failed" field in the retry record. Now
3055 it does not use this if it is later than than the arrival time of the
3056 message. Instead it uses the arrival time. This makes for better
3057 behaviour in cases where some deliveries succeed, thus re-setting the
3058 "first failed" field. An example is a quota failure for a huge message
3059 when small messages continue to be delivered. Without this change, the
3060 "time since failure" will always be short, possible causing more frequent
3061 delivery attempts for the huge message than are intended.

3094 address found for host xxx.xxx.xxx (during SMTP connection from NULL)"

3129PH/36 Now that the new test suite is complete, we can remove some of the

3133 same order.

PH
3158PH/42 The content-scanning code uses fopen() to create files in which to put
3159 message data. Previously it was not paying any attention to the mode of
3160 the files. Exim runs with umask(0) because the rest of the code creates
3161 files with open(), and sets the required mode explicitly. Thus, these
3162 files were ending up world-writeable. This was not a big issue, because,
3163 being within the spool directory, they were not world-accessible. I have
3164 created a function called modefopen, which takes an additional mode
3165 argument. It sets umask(777), creates the file, chmods it to the required
3166 mode, then resets the umask. All the relevant calls to fopen() in the
3167 content scanning code have been changed to use this function.

PH
3175PH/45 When the plaintext authenticator is running as a client, the server's
3176 challenges are checked to ensure they are valid base64 strings. By
3177 default, the authentication attempt is cancelled if an invalid string is
3178 received. Setting client_ignore_invalid_base64 true ignores these errors.
3179 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
3180 they are received. Thus, the responses can be made to depend on the
3181 challenges. If an invalid string is ignored, an empty string is placed in
3182 the variable.

3193PH/50 When an Exim quota was set without a file count quota, and mailbox_size
3194 was also set, the appendfile transport was unnecessarily scanning a
3195 directory of message files (e.g. for maildir delivery) to find the count
3196 of files (along with the size), even though it did not need this
3197 information. It now does the scan only if it needs to find either the
3198 size of the count of files.

3202PH/52 Two bugs concerned with error handling when the smtp transport is
3203 used in LMTP mode:
3204
3205 (i) Exim was not creating retry information for temporary errors given
3206 for individual recipients after the DATA command when the smtp transport
3207 was used in LMTP mode. This meant that they could be retried too
3208 frequently, and not timed out correctly.
3209
3210 (ii) Exim was setting the flag that allows error details to be returned
3211 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3212 recipients that were returned after the DATA command.
3213
3214PH/53 This is related to PH/52, but is more general: for any failing address,
3215 when detailed error information was permitted to be returned to the
3216 sender, but the error was temporary, then after the final timeout, only
3217 "retry timeout exceeded" was returned. Now it returns the full error as
3218 well as "retry timeout exceeded".
