8TF/01 Correctly close the server side of TLS when forking for delivery.
9
10 When a message was received over SMTP with TLS, Exim failed to clear up
11 the incoming connection properly after forking off the child process to
12 deliver the message. In some situations the subsequent outgoing
13 delivery connection happened to have the same fd number as the incoming
14 connection previously had. Exim would try to use TLS and fail, logging
15 a "Bad file descriptor" error.

186TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
187
188 When a queue runner is handling a message, Exim first routes the
189 recipient addresses, during which it prunes them based on the retry
190 hints database. After that it attempts to deliver the message to
191 any remaining recipients. It then updates the hints database using
192 the retry rules.
193
194 So if a recipient address works intermittently, it can get repeatedly
195 deferred at routing time. The retry hints record remains fresh so the
196 address never reaches the final cutoff time.
197
198 This is a fairly common occurrence when a user is bumping up against
199 their storage quota. Exim had some logic in its local delivery code
200 to deal with this. However it did not apply to per-recipient defers
201 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
202
1ddeb334
TF
203 This change adds a proper retry rule check during routing so that the
204 final cutoff time is checked against the message's age. We only do
205 this check if there is an address retry record and there is not a
206 domain retry record; this implies that previous attempts to handle
207 the address had the retry_use_local_parts option turned on. We use
208 this as an approximation for the destination being like a local
209 delivery, as in LMTP.
67bd1ab3
TF
210
211 I suspect this new check makes the old local delivery cutoff check
212 redundant, but I have not verified this so I left the code in place.

TF
214TF/02 Correct gecos expansion when From: is a prefix of the username.
215
216 Test 0254 submits a message to Exim with the header
217
218 Resent-From: f
219
220 When I ran the test suite under the user fanf2, Exim expanded
221 the header to contain my full name, whereas it should have added
222 a Resent-Sender: header. It erroneously treats any prefix of the
223 username as equal to the username.
224
225 This change corrects that bug.

246JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
247 Server implementation by Todd Lyons, client by JH.
248 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
249 config variable "prdr_enable" controls whether the server
250 advertises the facility. If the client requests PRDR a new
251 acl_data_smtp_prdr ACL is called once for each recipient, after
252 the body content is received and before the acl_smtp_data ACL.
253 The client is controlled by bolth of: a hosts_try_prdr option
254 on the smtp transport, and the server advertisement.
255 Default client logging of deliveries and rejections involving
256 PRDR are flagged with the string "PRDR".

266 This is now consistent with GnuTLS, and is now documented: the
267 previous undocumented portable approach to treating the option as

269 an empty string is now equivalent.

534TF/03 Make the exiwhat support code safe for signals. Previously Exim might
535 lock up or crash if it happened to be inside a call to libc when it
536 got a SIGUSR1 from exiwhat.
537
538 The SIGUSR1 handler appends the current process status to the process
539 log which is later printed by exiwhat. It used to use the general
540 purpose logging code to do this, but several functions it calls are
541 not safe for signals.
542
543 The new output code in the SIGUSR1 handler is specific to the process
544 log, and simple enough that it's easy to inspect for signal safety.
545 Removing some special cases also simplifies the general logging code.
546 Removing the spurious timestamps from the process log simplifies
547 exiwhat.

TF
549TF/04 Improved ratelimit ACL condition.
550
551 The /noupdate option has been deprecated in favour of /readonly which
552 has clearer semantics. The /leaky, /strict, and /readonly update modes
553 are mutually exclusive. The update mode is no longer included in the
554 database key; it just determines when the database is updated. (This
555 means that when you upgrde Exim will forget old rate measurements.)
556
557 Exim now checks that the per_* options are used with an update mode that
558 makes sense for the current ACL. For example, when Exim is processing a
559 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
560 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
561 must specify per_mail/readonly. If you omit the update mode it defaults to
562 /leaky where that makes sense (as before) or /readonly where required.
563
564 The /noupdate option is now undocumented but still supported for
565 backwards compatibility. It is equivalent to /readonly except that in
566 ACLs where /readonly is required you may specify /leaky/noupdate or
567 /strict/noupdate which are treated the same as /readonly.
568
569 A useful new feature is the /count= option. This is a generalization
570 of the per_byte option, so that you can measure the throughput of other
571 aggregate values. For example, the per_byte option is now equivalent
572 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
573
574 The per_rcpt option has been generalized using the /count= mechanism
575 (though it's more complicated than the per_byte equivalence). When it is
576 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
577 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
578 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
579 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
580 Note that using per_rcpt with a non-readonly update mode in more than
581 one ACL will cause the recipients to be double-counted. (The per_mail
582 and per_byte options don't have this problem.)
583
584 The handling of very low rates has changed slightly. If the computed rate
585 is less than the event's count (usually one) then this event is the first
586 after a long gap. In this case the rate is set to the same as this event's
587 count, so that the first message of a spam run is counted properly.
588
589 The major new feature is a mechanism for counting the rate of unique
590 events. The new per_addr option counts the number of different
591 recipients that someone has sent messages to in the last time period. It
592 behaves like per_rcpt if all the recipient addresses are different, but
593 duplicate recipient addresses do not increase the measured rate. Like
594 the /count= option this is a general mechanism, so the per_addr option
595 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
596 example, measure the rate that a client uses different sender addresses
597 with the options per_mail/unique=$sender_address. There are further
598 details in the main documentation.

1149 were called 'true' and it seems that C99 defines that as a reserved

1151 not include C99-style headers which use bools without triggering

1169
1170PH/01 Another patch from the Sieve maintainer.
1171
6a3bceb1
PH
1172PH/02 When an IPv6 address is converted to a string for single-key lookup
1173 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1174 dots are used instead of colons so that keys in lsearch files need not
1175 contain colons. This was done some time before quoting was made available
1176 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1177 (notated using the quote facility) so as to distinguish them from IPv4
1178 keys. This meant that lookups for IP addresses in host lists did not work
1179 for iplsearch lookups.
1180
1181 This has been fixed by arranging for IPv6 addresses to be expressed with
1182 colons if the lookup type is iplsearch. This is not incompatible, because
1183 previously such lookups could never work.
1184
1185 The situation is now rather anomolous, since one *can* have colons in
1186 ordinary lsearch keys. However, making the change in all cases is
1187 incompatible and would probably break a number of configurations.

MH
1192MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1193 conversion specification without a maximum field width, thereby enabling
1194 a rogue spamd server to cause a buffer overflow. While nobody in their
1195 right mind would setup Exim to query an untrusted spamd server, an
1196 attacker that gains access to a server running spamd could potentially
1197 exploit this vulnerability to run arbitrary code as the Exim user.

1202MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1203 a directory entry by the name of the lookup key. Previously, if a
1204 symlink pointed to a non-existing file or a file in a directory that
1205 Exim lacked permissions to read, a lookup for a key matching that
1206 symlink would fail. Now it is enough that a matching directory entry
1207 exists, symlink or not. (Bugzilla 503.)

PH
1390PH/29 SMTP synchronization checks are implemented when a command is read -
1391 there is a check that no more input is waiting when there shouldn't be
1392 any. However, for some commands, a delay in an ACL can mean that it is
1393 some time before the response is written. In this time, more input might
1394 arrive, invalidly. So now there are extra checks after an ACL has run for
1395 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1396 pipelining has not been advertised.

1411 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1412 was a macro that became an assignment, so it seemed to work. This has
1413 changed to a proper function call with a void return, hence the compile
1414 error. Exim's code has been fixed.

1442PH/40 When Exim receives a message, it writes the login name, uid, and gid of

1444 behaving confusingly. When first started, it used values for whoever
1445 started the daemon, but after a SIGHUP it used the Exim user (because it
1446 calls itself on a restart). I have changed the code so that it now always
1447 uses the Exim user.

1452 with PIPELINING or a stupid MUA), the error message that was given to the
1453 RCPT commands is included in the rejection of the DATA command. This is
1454 intended to be helpful for MUAs that show only the final error to their

PH
1470 the response to the final '.' that terminates a message, but only in the
1471 case where the client has not sent further data following the '.'
1472 (unfortunately, this is allowed). However, in many cases there won't be
1473 any further data because there won't be any more messages to send. A call
1474 to select() can be used: if it shows that the input is "ready", there is
1475 either input waiting, or the socket has been closed. An attempt to read
1476 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1477 would have sent an OK response which the client would never have see.

1488PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1489 fixed by 4.65/MH/01 (is this a record?) are fixed:
1490
1491 (i) An empty string was always treated as zero by the numeric comparison
1492 operators. This behaviour has been restored.
1493
1494 (ii) It is documented that the numeric comparison operators always treat
1495 their arguments as decimal numbers. This was broken in that numbers
1496 starting with 0 were being interpreted as octal.
1497
1498 While fixing these problems I realized that there was another issue that
1499 hadn't been noticed. Values of message_size_limit (both the global option
1500 and the transport option) were treated as octal if they started with 0.
1501 The documentation was vague. These values are now always treated as
1502 decimal, and I will make that clear in the documentation.

1519 large number of recipients for a single message is ridiculous
1520 (performance will be very, very poor), I have chosen to impose a limit
1521 rather than extend the field.

1528 leftover -K file (the existence of which was triggered by #402).

2b1c6e3a
PH
1546PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1547 callout verification, Exim cached a "reject" for the entire domain. This
1548 is correct for most verifications, but it is not correct for a recipient
1549 verification with use_sender or use_postmaster set, because in that case
1550 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1551 case of MAIL FROM:<> rejection from other early rejections (e.g.
1552 rejection of HELO). When verifying a recipient using a non-null MAIL
1553 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1554 Whatever the result of the callout, the value of the domain cache is
1555 left unchanged (for any other kind of callout, getting as far as trying
1556 RCPT means that the domain itself is ok).

PH
1587PH/10 Added the log_reject_target ACL modifier to specify where to log
1588 rejections.

26da7e20
PH
1590PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1591 hostname. This is wrong, because it relates to the incoming message (and
1592 probably the interface on which it is arriving) and not to the outgoing
1593 callout (which could be using a different interface). This has been
1594 changed to use the value of the helo_data option from the smtp transport
1595 instead - this is what is used when a message is actually being sent. If
1596 there is no remote transport (possible with a router that sets up host
1597 addresses), $smtp_active_hostname is used.
6ea85e9a 1598
14aa5a05 1599PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1600 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1601 (a) The code assumed that strncpy() returns a negative number on buffer
1602 overflow, which isn't the case. Replaced with Exim's string_format()
1603 function.
1604 (b) There were several signed/unsigned issues. I just did the minimum
1605 hacking in of casts. There is scope for a larger refactoring.
1606 (c) The code used strcasecmp() which is not a standard C function.
1607 Replaced with Exim's strcmpic() function.
1608 (d) The code set only $1; it now sets $auth1 as well.
1609 (e) A simple test gave the error "authentication client didn't specify
1610 service in request". It would seem that Dovecot has changed its
1611 interface. Fortunately there's a specification; I followed it and
1612 changed what the client sends and it appears to be working now.
1613
ff75a1f7
PH
1614PH/13 Added $message_headers_raw to provide the headers without RFC 2047
1615 decoding.
1616
e6f6568e
PH
1617PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1618 address A is aliased to B and C, where B exists and C does not. Without
1619 -v the output is "A verified" because verification stops after a
1620 successful redirection if more than one address is generated. However,
1621 with -v the child addresses are also verified. Exim was outputting "A
1622 failed to verify" and then showing the successful verification for C,
1623 with its parentage. It now outputs "B failed to verify", showing B's
1624 parentage before showing the successful verification of C.
1625
d6f6e0dc
PH
1626PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
1627 look up a TXT record in a specific list after matching in a combined
1628 list.
1629
322050c2
PH
1630PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1631 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1632 they consult the DNS. I had assumed they would set it the way they
1633 wanted; and indeed my experiments on Linux seem to show that in some
1634 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1635 To be on the safe side, however, I have now made the interface to
1636 host_find_byname() similar to host_find_bydns(), with an argument
1637 containing the DNS resolver options. The host_find_byname() function now
1638 sets these options at its start, just as host_find_bydns() does. The smtp
1639 transport options dns_qualify_single and dns_search_parents are passed to
1640 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1641 of host_find_byname() use the default settings of RES_DEFNAMES
1642 (qualify_single) but not RES_DNSRCH (search_parents).
1643
08955dd3
PH
1644PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1645 spool_read_header() do less string testing, by means of a preliminary
1646 switch on the second character of optional "-foo" lines. (This is
1647 overdue, caused by the large number of possibilities that now exist.
1648 Originally there were few.) While I was there, I also converted the
1649 str(n)cmp tests so they don't re-test the leading "-" and the first
1650 character, in the hope this might squeeze out yet more improvement.
1651
1eccaa59
PH
1652PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1653 flag allowing group syntax was set by the header_syntax check but not
1654 turned off, possible causing trouble later; (2) The flag was not being
1655 set at all for the header_verify test, causing "group"-style headers to
1656 be rejected. I have now set it in this case, and also caused header_
1657 verify to ignore an empty address taken from a group. While doing this, I
1658 came across some other cases where the code for allowing group syntax
1659 while scanning a header line wasn't quite right (mostly, not resetting
1660 the flag correctly in the right place). These bugs could have caused
1661 trouble for malformed header lines. I hope it is now all correct.
1662
602e59e5
PH
1663PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1664 with the "reply" argument non-NULL. The code, however (which originally
1665 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1666 but it didn't always do it. This confused somebody who was copying the
1667 code for some other use. I have removed all the tests.
1668
411ef850
PH
1669PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1670 feature that was used to support insecure browsers during the U.S. crypto
1671 embargo. It requires special client support, and Exim is probably the
1672 only MTA that supported it -- and would never use it because real RSA is
1673 always available. This code has been removed, because it had the bad
1674 effect of slowing Exim down by computing (never used) parameters for the
1675 RSA_EXPORT functionality.
1676
7befa435
PH
1677PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1678 authenticator to fail if there's a tab character in the incoming data
1679 (there should never be unless someone is messing about, as it's supposed
1680 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1681 if the connection is using TLS or if the remote IP is the same as the
1682 local IP, and the "valid-client-cert option" if a client certificate has
1683 been verified.
1684
48da4259 1685PH/22 As suggested by Dennis Davis, added a server_condition option to *all*
16ff981e
PH
1686 authenticators. This can be used for authorization after authentication
1687 succeeds. (In the case of plaintext, it servers for both authentication
1688 and authorization.)
1689
48da4259
PH
1690PH/23 Testing for tls_required and lost_connection in a retry rule didn't work
1691 if any retry times were supplied.
1692
d1d5595c
PH
1693PH/24 Exim crashed if verify=helo was activated during an incoming -bs
1694 connection, where there is no client IP address to check. In this
1695 situation, the verify now always succeeds.

fd700877
PH
1701PH/27 In a string expansion for a processed (not raw) header when multiple
1702 headers of the same name were present, leading whitespace was being
1703 removed from all of them, but trailing whitespace was being removed only
1704 from the last one. Now trailing whitespace is removed from each header

1705 before concatenation. Completely empty headers in a concatenation (as
1706 before) are ignored.
fd700877 1707
8dce1a6f
PH
1708PH/28 Fixed bug in backwards-compatibility feature of PH/09 (thanks to John
1709 Jetmore). It would have mis-read ACL variables from pre-4.61 spool files.
1710
17af4a17
PH
1711PH/29 [Removed. This was a change that I later backed out, and forgot to
1712 correct the ChangeLog entry (that I had efficiently created) before
1713 committing the later change.]
f6c332bd
PH
1714
1715PH/30 Exim was sometimes attempting to deliver messages that had suffered
1716 address errors (4xx response to RCPT) over the same connection as other
1717 messages routed to the same hosts. Such deliveries are always "forced",
1718 so retry times are not inspected. This resulted in far too many retries
1719 for the affected addresses. The effect occurred only when there were more
1720 hosts than the hosts_max_try setting in the smtp transport when it had
1721 the 4xx errors. Those hosts that it had tried were not added to the list
1722 of hosts for which the message was waiting, so if all were tried, there
1723 was no problem. Two fixes have been applied:
1724
1725 (i) If there are any address or message errors in an SMTP delivery, none
1726 of the hosts (tried or untried) are now added to the list of hosts
1727 for which the message is waiting, so the message should not be a
1728 candidate for sending over the same connection that was used for a
1729 successful delivery of some other message. This seems entirely
1730 reasonable: after all the message is NOT "waiting for some host".
1731 This is so "obvious" that I'm not sure why it wasn't done
1732 previously. Hope I haven't missed anything, but it can't do any
1733 harm, as the worst effect is to miss an optimization.
1734
1735 (ii) If, despite (i), such a delivery is accidentally attempted, the
1736 routing retry time is respected, so at least it doesn't keep
1737 hammering the server.

1740 in ${readsocket because some servers need this prod.

PH
1742PH/32 Added some extra debug output when updating a wait-xxx database.
1743
0d85fa3f
PH
1744PH/33 The hint "could be header name not terminated by colon", which has been
1745 given for certain expansion errors for a long time, was not being given
1746 for the ${if def:h_colon_omitted{... case.
1747
1bf43b78
PH
1748PH/34 The spec says: "With one important exception, whenever a domain list is
1749 being scanned, $domain contains the subject domain." There was at least
1750 one case where this was not true.
1751
520de300
PH
1752PH/35 The error "getsockname() failed: connection reset by peer" was being
1753 written to the panic log as well as the main log, but it isn't really
1754 panic-worthy as it just means the connection died rather early on. I have
1755 removed the panic log writing for the ECONNRESET error when getsockname()
1756 fails.
1757
48c7f9e2
PH
1758PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1759 runs only) independently of the message's sender address. This meant
1760 that, if the 4xx error was in fact related to the sender, a different
1761 message to the same recipient with a different sender could confuse
1762 things. In particualar, this can happen when sending to a greylisting
1763 server, but other circumstances could also provoke similar problems.
1764 I have changed the default so that the retry time for these errors is now
1765 based a combination of the sender and recipient addresses. This change
1766 can be overridden by setting address_retry_include_sender=false in the
1767 smtp transport.
1768
99ea1c86
PH
1769PH/37 For LMTP over TCP/IP (the smtp transport), error responses from the
1770 remote server are returned as part of bounce messages. This was not
1771 happening for LMTP over a pipe (the lmtp transport), but now it is the
1772 same for both kinds of LMTP.
1773
a2042e78
PH
1774PH/38 Despite being documented as not happening, Exim was rewriting addresses
1775 in header lines that were in fact CNAMEs. This is no longer the case.
1776
4fbcfc2e
PH
1777PH/39 If -R or -S was given with -q<time>, the effect of -R or -S was ignored,
1778 and queue runs started by the daemon processed all messages. This has
1779 been fixed so that -R and -S can now usefully be given with -q<time>.

1790 a message is delivered. (The old names remain recognized, of course.)

2035PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2037 Unfortunately, if there is a major crisis, such as a disk failure,
2038 tcp-wrappers gives "deny", whereas what one would like would be some
2039 kind of temporary error. A kludge has been added to help with this.
2040 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2041 554 error is used if errno is still zero or contains ENOENT (which occurs
2042 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2043 451 error is used.

2079PH/01 The code for finding all the local interface addresses on a FreeBSD
2080 system running IPv6 was broken. This may well have applied to all BSD
2081 systems, as well as to others that have similar system calls. The broken
2082 code found IPv4 interfaces correctly, but gave incorrect values for the
2083 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2084 that it would not match correctly against @[] and not recognize the IPv6
2085 addresses as local.

2128 autoreply, Exim could try to deliver to a non-existent relative file

2151 (a) Failures to set uid/gid, the current directory, or a process leader
2152 in a subprocess such as that created by queryprogram now generate
2153 suitable debugging ouput when -d is set.

2164 Instead, it always explicitly searches for A/AAAA records. This avoids
2165 major problems that occur when a DNS server includes only records of one
2166 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2167 fixed another bug: if SRV records were looked up and the corresponding
2168 address records were *not* found in the additional section, the port
2169 values from the SRV records were lost.

2179PH/19 When calculating a retry time, Exim used to measure the "time since
2180 failure" by looking at the "first failed" field in the retry record. Now
2181 it does not use this if it is later than than the arrival time of the
2182 message. Instead it uses the arrival time. This makes for better
2183 behaviour in cases where some deliveries succeed, thus re-setting the
2184 "first failed" field. An example is a quota failure for a huge message
2185 when small messages continue to be delivered. Without this change, the
2186 "time since failure" will always be short, possible causing more frequent
2187 delivery attempts for the huge message than are intended.

PH
2284PH/42 The content-scanning code uses fopen() to create files in which to put
2285 message data. Previously it was not paying any attention to the mode of
2286 the files. Exim runs with umask(0) because the rest of the code creates
2287 files with open(), and sets the required mode explicitly. Thus, these
2288 files were ending up world-writeable. This was not a big issue, because,
2289 being within the spool directory, they were not world-accessible. I have
2290 created a function called modefopen, which takes an additional mode
2291 argument. It sets umask(777), creates the file, chmods it to the required
2292 mode, then resets the umask. All the relevant calls to fopen() in the

2330
2331 (i) Exim was not creating retry information for temporary errors given

2333 was used in LMTP mode. This meant that they could be retried too
2334 frequently, and not timed out correctly.
2335
2336 (ii) Exim was setting the flag that allows error details to be returned
2337 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2338 recipients that were returned after the DATA command.
2339
2340PH/53 This is related to PH/52, but is more general: for any failing address,
2341 when detailed error information was permitted to be returned to the

2414PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2415 function verify_get_ident() calls ip_connect() to connect a socket, but
2416 if the "connect()" function timed out, ip_connect() used to close the
2417 socket. However, verify_get_ident() also closes the socket later, and in
2418 between Exim writes to the log, which may get opened at this point. When
2419 the socket was closed in ip_connect(), the log could get the same file
2420 descriptor number as the socket. This naturally causes chaos. The fix is
2421 not to close the socket in ip_connect(); the socket should be closed by
2422 the function that creates it. There was only one place in the code where
2423 this was missing, in the iplookup router, which I don't think anybody now
2424 uses, but I've fixed it anyway.

2447
2448 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2449 string.
2450
2451 (3) Reset the variables that are obtained from the first argument of
2452 ${prvscheck and used in the second argument before leaving the code,
2453 because their memory is reclaimed, so using them afterwards may do
2454 silly things.
2455
2456 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2457 one (it's much easier than Tom thought :-).

2480PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2481 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2482 not being looked up in the rDNS to get a host name, Exim was showing the
2483 IP address twice in Received: lines, even though the IP addresses were
2484 identical. For example:
2485
2486 Received: from [1.2.3.4] (helo=[1.2.3.4])
2487
2488 However, if the real host name was known, it was omitting the HELO data
2489 if it matched the actual IP address. This has been tidied up so that it
2490 doesn't show the same IP address twice.

2520
2521 in the messages that it generates (bounce messages and others, such as
2522 warnings). In the case of bounce messages for non-SMTP mesages, there was
2523 also a typo: it was using "Auto_submitted" (underscore instead of
2524 hyphen). Since every message generated by Exim is necessarily in response
2525 to another message, thes have all been changed to:
2526
2527 Auto-Submitted: auto-replied
2528
2529 in accordance with these statements in the RFC:
2530
2531 The auto-replied keyword:
2532
2533 - SHOULD be used on messages sent in direct response to another
2534 message by an automatic process,
2535

2538 - MAY be used on Delivery Status Notifications (DSNs) and Message
2539 Disposition Notifications (MDNs),

2579PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated

2581 the IP address, check_host() was doing a simple string comparison with
2582 addresses acquired from the DNS when checking that the found name did
2583 have the original IP as one of its addresses. Since any found IPv6
2584 addresses are likely to be in abbreviated form, the comparison could
2585 fail. Luckily, there already exists a function for doing the comparison
2586 by converting both addresses to binary, so now that is used instead of
2587 the text comparison.

2885 with the definition in sysexits.h (which is #included earlier).
2886 Fortunately, Exim does not actually use EX_OK. The code used to try to
2887 preserve the sysexits.h value, by assumimg that macro definitions were
2888 scanned for macro replacements. I have been disabused of this notion,

2895 would take for ever. The timeout is now adjusted when this happens. It
2896 doesn't have to be particularly precise.

3104
3105PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3106 that changes the way the GnuTLS parameters are stored in the cache file.
3107 The new format can be generated externally. For backward compatibility,
3108 if the data in the cache doesn't make sense, Exim assumes it has read an
3109 old-format file, and it generates new data and writes a new file. This
3110 means that you can't go back to an older release without removing the
3111 file.
3112
3113PH/03 A redirect router that has both "unseen" and "one_time" set does not
3114 work if there are any delivery delays because "one_time" forces the
3115 parent to be marked "delivered", so its unseen clone is never tried
3116 again. For this reason, Exim now forbids the simultaneous setting of
3117 these two options.
3118
3119PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3120 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3121 entry if you want to know the details. The fix, however, neglected to
3122 consider the case when local delivery batching is involved. The test for
3123 "previously delivered" was not happening when checking to see if an
3124 address could be batched with a previous (undelivered) one; under
3125 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3126 address.

3131PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3132 header_syntax) but Exim was just ignoring anything given after a slash.
3133 In particular, this caused confusion with an attempt to use "verify =
3134 reverse_host_lookup/defer_ok". An error is now given when options are
3135 supplied for verify items that do not have them. (Maybe reverse_host_
3136 lookup should have a defer_ok option, but that's a different point.)
3137
3138PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

3188PH/19 When an Exim process that is running as root has to create an Exim log
3189 file, it does so in a subprocess that runs as exim:exim so as to get the
3190 ownership right at creation (otherwise, other Exim processes might see
3191 the file with the wrong ownership). There was no test for failure of this
3192 fork() call, which would lead to the process getting stuck as it waited
3193 for a non-existent subprocess. Forks do occasionally fail when resources
3194 run out. I reviewed all the other calls to fork(); they all seem to check
3195 for failure.

3197PH/20 When checking for unexpected SMTP input at connect time (before writing
3198 the banner), Exim was not dealing correctly with a non-positive return
3199 from the read() function. If the client had disconnected by this time,
3200 the result was a log entry for a synchronization error with an empty
3201 string after "input=" when read() returned zero. If read() returned -1
3202 (an event I could not check), uninitialized data bytes were printed.

PH
3214PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3215 hadn't been configured. The fix is from Juergen Kreileder, who
3216 understands it better than I do:
3217
3218 "Here's what I see happening with three configured cyrus_sasl
3219 authenticators configured (plain, login, cram-md5):
3220
3221 On startup auth_cyrus_sasl_init() gets called for each of these.
3222 This means three calls to sasl_listmech() without a specified mech_list.
3223 => SASL tests which mechs of all available mechs actually work
3224 => three warnings about OTP not working
3225 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3226
3227 With the patch, sasl_listmech() also gets called three times. But now
3228 SASL's mech_list option is set to the server_mech specified in the the
3229 authenticator. Or in other words, the answer from sasl_listmech()
3230 gets limited to just the mech you're testing for (which is different
3231 for each call.)
3232 => the return list contains just 'plain' or 'login', 'cram-md5' or
3233 nothing depending on the value of ob->server_mech.
3234
3235 I've just tested the patch: Authentication still works fine,
3236 unavailable mechs specified in the exim configuration are still
3237 caught, and the auth.log warnings about OTP are gone."

3269 . Two addresses routed to the same list of hosts;

3272 . First host gives temporary error to second address;
3273 . Second host offers TLS and a TLS session is established;
3274 . Second host accepts second address.

PH
3301PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3302 the grounds that routing the same address twice would always produce the
3303 same answer. This might have been true once, but it is certainly no
3304 longer true now. Routing a child address may depend on the previous
3305 routing that produced that child. Some complicated redirection strategies
3306 went wrong when messages had multiple recipients, and made Exim's
3307 behaviour dependent on the order in which the addresses were given.
3308
3309 I have moved the duplicate checking until after the routing is complete.
3310 Exim scans the addresses that are assigned to local and remote
3311 transports, and removes any duplicates. This means that more work will be
3312 done, as duplicates will always all be routed, but duplicates are
3313 presumably rare, so I don't expect this is of any significance.
3314
3315 For deliveries to pipes, files, and autoreplies, the duplicate checking
3316 still happens during the routing process, since they are not going to be
3317 routed further.

3322 connection it has accepted, or it never writes response data. The exiscan
3323 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
3324 blindly assumes that writes won't block so it may never time out."

3341
3342 (a) An SMTP error message from a remote host;

3345 (d) A message specified in a FAIL return from the queryprogram router;
3346 (e) A message specified by the cannot_route_message router option.
3347
3348 In these cases only, Exim does include the error details in bounce and
3349 warning messages. There are also a few cases where bland messages such
3350 as "unrouteable address" or "local delivery error" are given.

3358PH/45 In a pipe transport, although a timeout while waiting for the pipe
3359 process to complete was treated as a delivery failure, a timeout while
3360 writing the message to the pipe was logged, but erroneously treated as a
3361 successful delivery. Such timeouts include transport filter timeouts. For
3362 consistency with the overall process timeout, these timeouts are now
3363 treated as errors, giving rise to delivery failures by default. However,
3364 there is now a new Boolean option for the pipe transport called
3365 timeout_defer, which, if set TRUE, converts the failures into defers for
3366 both kinds of timeout. A transport filter timeout is now identified in
3367 the log output.
