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.

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.

30 identical IP addresses on different listening ports. Will also affect
31 "exiwhat" output.

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
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.

255 TCP connections (such as for Spamd) unless the daemon successfully set
256 Fast Open mode on its listening sockets. This fixes breakage seen on
257 too-old kernels or those not configured for Fast Open, at the cost of

320JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
321 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
322 or even an in-clear connection were permitted. Now, if the host lookup
323 was dnssec and dane was requested then the host is only used if the
324 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
325 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
326 if one fails this test.
327 This means that a poorly-configured remote DNS will make it incommunicado;
328 but it protects against a DNS-interception attack on it.

1142TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
1143
1144 When a queue runner is handling a message, Exim first routes the
1145 recipient addresses, during which it prunes them based on the retry
1146 hints database. After that it attempts to deliver the message to
1147 any remaining recipients. It then updates the hints database using
1148 the retry rules.
1149
1150 So if a recipient address works intermittently, it can get repeatedly
1151 deferred at routing time. The retry hints record remains fresh so the
1152 address never reaches the final cutoff time.
1153
1154 This is a fairly common occurrence when a user is bumping up against
1155 their storage quota. Exim had some logic in its local delivery code
1156 to deal with this. However it did not apply to per-recipient defers
1157 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1158
1ddeb334
TF
1159 This change adds a proper retry rule check during routing so that the
1160 final cutoff time is checked against the message's age. We only do
1161 this check if there is an address retry record and there is not a
1162 domain retry record; this implies that previous attempts to handle
1163 the address had the retry_use_local_parts option turned on. We use
1164 this as an approximation for the destination being like a local
1165 delivery, as in LMTP.
67bd1ab3
TF
1166

1176 When I ran the test suite under the user fanf2, Exim expanded

1490TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1491 lock up or crash if it happened to be inside a call to libc when it
1492 got a SIGUSR1 from exiwhat.
1493
1494 The SIGUSR1 handler appends the current process status to the process
1495 log which is later printed by exiwhat. It used to use the general
1496 purpose logging code to do this, but several functions it calls are
1497 not safe for signals.
1498
1499 The new output code in the SIGUSR1 handler is specific to the process
1500 log, and simple enough that it's easy to inspect for signal safety.
1501 Removing some special cases also simplifies the general logging code.
1502 Removing the spurious timestamps from the process log simplifies
1503 exiwhat.

c99ce5c9
TF
1505TF/04 Improved ratelimit ACL condition.
1506
1507 The /noupdate option has been deprecated in favour of /readonly which
1508 has clearer semantics. The /leaky, /strict, and /readonly update modes
1509 are mutually exclusive. The update mode is no longer included in the
1510 database key; it just determines when the database is updated. (This
4c04137d 1511 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1512
1513 Exim now checks that the per_* options are used with an update mode that
1514 makes sense for the current ACL. For example, when Exim is processing a
1515 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1516 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1517 must specify per_mail/readonly. If you omit the update mode it defaults to
1518 /leaky where that makes sense (as before) or /readonly where required.
1519
1520 The /noupdate option is now undocumented but still supported for
1521 backwards compatibility. It is equivalent to /readonly except that in
1522 ACLs where /readonly is required you may specify /leaky/noupdate or
1523 /strict/noupdate which are treated the same as /readonly.
1524
1525 A useful new feature is the /count= option. This is a generalization
1526 of the per_byte option, so that you can measure the throughput of other
1527 aggregate values. For example, the per_byte option is now equivalent
1528 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1529
1530 The per_rcpt option has been generalized using the /count= mechanism
1531 (though it's more complicated than the per_byte equivalence). When it is
1532 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1533 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1534 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1535 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1536 Note that using per_rcpt with a non-readonly update mode in more than
1537 one ACL will cause the recipients to be double-counted. (The per_mail
1538 and per_byte options don't have this problem.)
1539
1540 The handling of very low rates has changed slightly. If the computed rate
1541 is less than the event's count (usually one) then this event is the first
1542 after a long gap. In this case the rate is set to the same as this event's
1543 count, so that the first message of a spam run is counted properly.
1544
1545 The major new feature is a mechanism for counting the rate of unique
1546 events. The new per_addr option counts the number of different
1547 recipients that someone has sent messages to in the last time period. It
1548 behaves like per_rcpt if all the recipient addresses are different, but
1549 duplicate recipient addresses do not increase the measured rate. Like
1550 the /count= option this is a general mechanism, so the per_addr option
1551 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1552 example, measure the rate that a client uses different sender addresses

2104 Note to Michael Haardt: I had to rename some vars in sieve.c. They
2105 were called 'true' and it seems that C99 defines that as a reserved
2106 keyword to be used with 'bool' variable types. That means you could
2107 not include C99-style headers which use bools without triggering

2125
2126PH/01 Another patch from the Sieve maintainer.
2127
6a3bceb1
PH
2128PH/02 When an IPv6 address is converted to a string for single-key lookup
2129 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
2130 dots are used instead of colons so that keys in lsearch files need not
2131 contain colons. This was done some time before quoting was made available
2132 in lsearch files. However, iplsearch files do require colons in IPv6 keys
2133 (notated using the quote facility) so as to distinguish them from IPv4
2134 keys. This meant that lookups for IP addresses in host lists did not work
2135 for iplsearch lookups.
2136
2137 This has been fixed by arranging for IPv6 addresses to be expressed with
2138 colons if the lookup type is iplsearch. This is not incompatible, because
2139 previously such lookups could never work.
2140
4c04137d 2141 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2142 ordinary lsearch keys. However, making the change in all cases is
2143 incompatible and would probably break a number of configurations.

MH
2148MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2149 conversion specification without a maximum field width, thereby enabling
2150 a rogue spamd server to cause a buffer overflow. While nobody in their
2151 right mind would setup Exim to query an untrusted spamd server, an
2152 attacker that gains access to a server running spamd could potentially
2153 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
2158MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2159 a directory entry by the name of the lookup key. Previously, if a
2160 symlink pointed to a non-existing file or a file in a directory that
2161 Exim lacked permissions to read, a lookup for a key matching that
2162 symlink would fail. Now it is enough that a matching directory entry
2163 exists, symlink or not. (Bugzilla 503.)

2240 if a client was not listed at all, or was listed with a value other than

PH
2346PH/29 SMTP synchronization checks are implemented when a command is read -
2347 there is a check that no more input is waiting when there shouldn't be
2348 any. However, for some commands, a delay in an ACL can mean that it is
2349 some time before the response is written. In this time, more input might
2350 arrive, invalidly. So now there are extra checks after an ACL has run for
2351 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2352 pipelining has not been advertised.

2367 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
2368 was a macro that became an assignment, so it seemed to work. This has

2408 with PIPELINING or a stupid MUA), the error message that was given to the

PH
2426 the response to the final '.' that terminates a message, but only in the
2427 case where the client has not sent further data following the '.'
2428 (unfortunately, this is allowed). However, in many cases there won't be
2429 any further data because there won't be any more messages to send. A call
2430 to select() can be used: if it shows that the input is "ready", there is
2431 either input waiting, or the socket has been closed. An attempt to read
2432 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2433 would have sent an OK response which the client would never have see.

2443
2444PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2445 fixed by 4.65/MH/01 (is this a record?) are fixed:
2446
2447 (i) An empty string was always treated as zero by the numeric comparison
2448 operators. This behaviour has been restored.
2449
2450 (ii) It is documented that the numeric comparison operators always treat
2451 their arguments as decimal numbers. This was broken in that numbers
2452 starting with 0 were being interpreted as octal.
2453
2454 While fixing these problems I realized that there was another issue that
2455 hadn't been noticed. Values of message_size_limit (both the global option
2456 and the transport option) were treated as octal if they started with 0.
2457 The documentation was vague. These values are now always treated as
2458 decimal, and I will make that clear in the documentation.

2474 is held in a short int, deliveries were likely to be lost. As such a
2475 large number of recipients for a single message is ridiculous
2476 (performance will be very, very poor), I have chosen to impose a limit
2477 rather than extend the field.

2b1c6e3a
PH
2502PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2503 callout verification, Exim cached a "reject" for the entire domain. This
2504 is correct for most verifications, but it is not correct for a recipient
2505 verification with use_sender or use_postmaster set, because in that case
2506 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2507 case of MAIL FROM:<> rejection from other early rejections (e.g.
2508 rejection of HELO). When verifying a recipient using a non-null MAIL
2509 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2510 Whatever the result of the callout, the value of the domain cache is
2511 left unchanged (for any other kind of callout, getting as far as trying
2512 RCPT means that the domain itself is ok).

2546PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2548 probably the interface on which it is arriving) and not to the outgoing
2549 callout (which could be using a different interface). This has been
2550 changed to use the value of the helo_data option from the smtp transport
2551 instead - this is what is used when a message is actually being sent. If
2552 there is no remote transport (possible with a router that sets up host
2553 addresses), $smtp_active_hostname is used.

7befa435 2556 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2557 (a) The code assumed that strncpy() returns a negative number on buffer
2558 overflow, which isn't the case. Replaced with Exim's string_format()
2559 function.
2560 (b) There were several signed/unsigned issues. I just did the minimum
2561 hacking in of casts. There is scope for a larger refactoring.
2562 (c) The code used strcasecmp() which is not a standard C function.
2563 Replaced with Exim's strcmpic() function.
2564 (d) The code set only $1; it now sets $auth1 as well.
2565 (e) A simple test gave the error "authentication client didn't specify
2566 service in request". It would seem that Dovecot has changed its
2567 interface. Fortunately there's a specification; I followed it and
2568 changed what the client sends and it appears to be working now.

2574 address A is aliased to B and C, where B exists and C does not. Without
2575 -v the output is "A verified" because verification stops after a
2576 successful redirection if more than one address is generated. However,
2577 with -v the child addresses are also verified. Exim was outputting "A
2578 failed to verify" and then showing the successful verification for C,
2579 with its parentage. It now outputs "B failed to verify", showing B's
2580 parentage before showing the successful verification of C.

2585
322050c2
PH
2586PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2587 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2588 they consult the DNS. I had assumed they would set it the way they
2589 wanted; and indeed my experiments on Linux seem to show that in some
2590 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2591 To be on the safe side, however, I have now made the interface to
2592 host_find_byname() similar to host_find_bydns(), with an argument
2593 containing the DNS resolver options. The host_find_byname() function now
2594 sets these options at its start, just as host_find_bydns() does. The smtp
2595 transport options dns_qualify_single and dns_search_parents are passed to
2596 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2597 of host_find_byname() use the default settings of RES_DEFNAMES
2598 (qualify_single) but not RES_DNSRCH (search_parents).

2600PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2601 spool_read_header() do less string testing, by means of a preliminary
2602 switch on the second character of optional "-foo" lines. (This is
2603 overdue, caused by the large number of possibilities that now exist.
2604 Originally there were few.) While I was there, I also converted the
2605 str(n)cmp tests so they don't re-test the leading "-" and the first
2606 character, in the hope this might squeeze out yet more improvement.

PH
2608PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2609 flag allowing group syntax was set by the header_syntax check but not
2610 turned off, possible causing trouble later; (2) The flag was not being
2611 set at all for the header_verify test, causing "group"-style headers to
2612 be rejected. I have now set it in this case, and also caused header_
2613 verify to ignore an empty address taken from a group. While doing this, I
2614 came across some other cases where the code for allowing group syntax
2615 while scanning a header line wasn't quite right (mostly, not resetting
2616 the flag correctly in the right place). These bugs could have caused
2617 trouble for malformed header lines. I hope it is now all correct.

PH
2619PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

2622 but it didn't always do it. This confused somebody who was copying the
2623 code for some other use. I have removed all the tests.

PH
2625PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2626 feature that was used to support insecure browsers during the U.S. crypto
2627 embargo. It requires special client support, and Exim is probably the
2628 only MTA that supported it -- and would never use it because real RSA is
2629 always available. This code has been removed, because it had the bad
2630 effect of slowing Exim down by computing (never used) parameters for the
2631 RSA_EXPORT functionality.

2636 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2637 if the connection is using TLS or if the remote IP is the same as the
2638 local IP, and the "valid-client-cert option" if a client certificate has
2639 been verified.

2670
2671PH/30 Exim was sometimes attempting to deliver messages that had suffered
2672 address errors (4xx response to RCPT) over the same connection as other
2673 messages routed to the same hosts. Such deliveries are always "forced",
2674 so retry times are not inspected. This resulted in far too many retries
2675 for the affected addresses. The effect occurred only when there were more
2676 hosts than the hosts_max_try setting in the smtp transport when it had
2677 the 4xx errors. Those hosts that it had tried were not added to the list
2678 of hosts for which the message was waiting, so if all were tried, there
2679 was no problem. Two fixes have been applied:
2680
2681 (i) If there are any address or message errors in an SMTP delivery, none
2682 of the hosts (tried or untried) are now added to the list of hosts
2683 for which the message is waiting, so the message should not be a
2684 candidate for sending over the same connection that was used for a
2685 successful delivery of some other message. This seems entirely
2686 reasonable: after all the message is NOT "waiting for some host".
2687 This is so "obvious" that I'm not sure why it wasn't done
2688 previously. Hope I haven't missed anything, but it can't do any
2689 harm, as the worst effect is to miss an optimization.

PH
2714PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue

2716 that, if the 4xx error was in fact related to the sender, a different
2717 message to the same recipient with a different sender could confuse
4c04137d 2718 things. In particular, this can happen when sending to a greylisting

2719 server, but other circumstances could also provoke similar problems.
2720 I have changed the default so that the retry time for these errors is now
2721 based a combination of the sender and recipient addresses. This change

2995 kind of temporary error. A kludge has been added to help with this.
2996 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2997 554 error is used if errno is still zero or contains ENOENT (which occurs
2998 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

3082 syntactically invalid From: or Reply-to: line, and a filter used this to
3083 generate an autoreply, and therefore failed to obtain an address for the
3084 autoreply, Exim could try to deliver to a non-existent relative file
3085 name, causing unrelated and misleading errors. What now happens is that
3086 it logs this as a hard delivery error, but does not attempt to create a
3087 bounce message.

3096PH/13 Domain literals for IPv6 were not recognized unless IPv6 support was
3097 compiled. In many other places in Exim, IPv6 addresses are always
3098 recognized, so I have changed this. It also means that IPv4 domain
3099 literals of the form [IPV4:n.n.n.n] are now always recognized.

3101PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
3102 used if the router is not running as root, for example, when verifying at
3103 ACL time, or when using -bh. The debugging output from this situation was
3104 non-existent - all you got was a failure to exec. I have made two
3105 changes:
3106
3107 (a) Failures to set uid/gid, the current directory, or a process leader
3108 in a subprocess such as that created by queryprogram now generate
4c04137d 3109 suitable debugging output when -d is set.

3110
3111 (b) The queryprogram router detects when it is not running as root,

3113 the subprocess without attempting to change uid/gid.

3118PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
3119 additional section of a DNS packet that returns MX or SRV records.
3120 Instead, it always explicitly searches for A/AAAA records. This avoids
3121 major problems that occur when a DNS server includes only records of one
3122 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
3123 fixed another bug: if SRV records were looked up and the corresponding
3124 address records were *not* found in the additional section, the port
3125 values from the SRV records were lost.

3127PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

3131PH/18 If quota_warn_message contains a From: header, Exim now refrains from

3133 errors_reply_to option, if set, is not used.

PH
3135PH/19 When calculating a retry time, Exim used to measure the "time since
3136 failure" by looking at the "first failed" field in the retry record. Now
3137 it does not use this if it is later than than the arrival time of the
3138 message. Instead it uses the arrival time. This makes for better
3139 behaviour in cases where some deliveries succeed, thus re-setting the
3140 "first failed" field. An example is a quota failure for a huge message
3141 when small messages continue to be delivered. Without this change, the
3142 "time since failure" will always be short, possible causing more frequent
3143 delivery attempts for the huge message than are intended.

3162
3163PH/24 An host item such as 1.2.3.4/abc was being treated as the IP address

PH
3240PH/42 The content-scanning code uses fopen() to create files in which to put
3241 message data. Previously it was not paying any attention to the mode of
3242 the files. Exim runs with umask(0) because the rest of the code creates
3243 files with open(), and sets the required mode explicitly. Thus, these
3244 files were ending up world-writeable. This was not a big issue, because,
3245 being within the spool directory, they were not world-accessible. I have
3246 created a function called modefopen, which takes an additional mode
3247 argument. It sets umask(777), creates the file, chmods it to the required
3248 mode, then resets the umask. All the relevant calls to fopen() in the
3249 content scanning code have been changed to use this function.

3257PH/45 When the plaintext authenticator is running as a client, the server's
3258 challenges are checked to ensure they are valid base64 strings. By
3259 default, the authentication attempt is cancelled if an invalid string is
3260 received. Setting client_ignore_invalid_base64 true ignores these errors.
3261 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
3262 they are received. Thus, the responses can be made to depend on the
3263 challenges. If an invalid string is ignored, an empty string is placed in
3264 the variable.
