5Exim version 4.85
6-----------------
7TL/01 When running the test suite, the README says that variables such as
8 no_msglog_check are global and can be placed anywhere in a specific
9 test's script, however it was observed that placement needed to be near
10 the beginning for it to behave that way. Changed the runtest perl
11 script to read through the entire script once to detect and set these
12 variables, reset to the beginning of the script, and then run through
13 the script parsing/test process like normal.

15TL/02 The BSD's have an arc4random API. One of the functions to induce
16 adding randomness was arc4random_stir(), but it has been removed in
17 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
18 function when detected.

TL
23TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
24 syntax errors in an expansion can be treated as a string instead of
25 logging or causing an error, due to the internal use of bool_lax
26 instead of bool when processing it.

40JH/05 Fix results-pipe from transport process. Several recipients, combined
41 with certificate use, exposed issues where response data items split
42 over buffer boundaries were not parsed properly. This eventually
43 resulted in duplicates being sent. This issue only became common enough
44 to notice due to the introduction of conection certificate information,
45 the item size being so much larger. Found and fixed by Wolfgang Breyha.

62Exim version 4.83
63-----------------
64
65TF/01 Correctly close the server side of TLS when forking for delivery.
66
67 When a message was received over SMTP with TLS, Exim failed to clear up
68 the incoming connection properly after forking off the child process to
69 deliver the message. In some situations the subsequent outgoing
70 delivery connection happened to have the same fd number as the incoming
71 connection previously had. Exim would try to use TLS and fail, logging
72 a "Bad file descriptor" error.

TF
318TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
319
320 When a queue runner is handling a message, Exim first routes the
321 recipient addresses, during which it prunes them based on the retry
322 hints database. After that it attempts to deliver the message to
323 any remaining recipients. It then updates the hints database using
324 the retry rules.
325
326 So if a recipient address works intermittently, it can get repeatedly
327 deferred at routing time. The retry hints record remains fresh so the
328 address never reaches the final cutoff time.
329
330 This is a fairly common occurrence when a user is bumping up against
331 their storage quota. Exim had some logic in its local delivery code
332 to deal with this. However it did not apply to per-recipient defers
333 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
334
1ddeb334
TF
335 This change adds a proper retry rule check during routing so that the
336 final cutoff time is checked against the message's age. We only do
337 this check if there is an address retry record and there is not a
338 domain retry record; this implies that previous attempts to handle
339 the address had the retry_use_local_parts option turned on. We use
340 this as an approximation for the destination being like a local
341 delivery, as in LMTP.
67bd1ab3
TF
342
343 I suspect this new check makes the old local delivery cutoff check
344 redundant, but I have not verified this so I left the code in place.

351
352 When I ran the test suite under the user fanf2, Exim expanded
353 the header to contain my full name, whereas it should have added
354 a Resent-Sender: header. It erroneously treats any prefix of the
355 username as equal to the username.

357 This change corrects that bug.

378JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
379 Server implementation by Todd Lyons, client by JH.
380 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
381 config variable "prdr_enable" controls whether the server
382 advertises the facility. If the client requests PRDR a new
383 acl_data_smtp_prdr ACL is called once for each recipient, after
384 the body content is received and before the acl_smtp_data ACL.
385 The client is controlled by bolth of: a hosts_try_prdr option
386 on the smtp transport, and the server advertisement.
387 Default client logging of deliveries and rejections involving
388 PRDR are flagged with the string "PRDR".

666TF/03 Make the exiwhat support code safe for signals. Previously Exim might
667 lock up or crash if it happened to be inside a call to libc when it
668 got a SIGUSR1 from exiwhat.
669
670 The SIGUSR1 handler appends the current process status to the process
671 log which is later printed by exiwhat. It used to use the general
672 purpose logging code to do this, but several functions it calls are
673 not safe for signals.
674
675 The new output code in the SIGUSR1 handler is specific to the process
676 log, and simple enough that it's easy to inspect for signal safety.
677 Removing some special cases also simplifies the general logging code.
678 Removing the spurious timestamps from the process log simplifies
679 exiwhat.
680
c99ce5c9
TF
681TF/04 Improved ratelimit ACL condition.
682
683 The /noupdate option has been deprecated in favour of /readonly which
684 has clearer semantics. The /leaky, /strict, and /readonly update modes
685 are mutually exclusive. The update mode is no longer included in the
686 database key; it just determines when the database is updated. (This
687 means that when you upgrde Exim will forget old rate measurements.)
688
689 Exim now checks that the per_* options are used with an update mode that
690 makes sense for the current ACL. For example, when Exim is processing a
691 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
692 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
693 must specify per_mail/readonly. If you omit the update mode it defaults to
694 /leaky where that makes sense (as before) or /readonly where required.
695
696 The /noupdate option is now undocumented but still supported for
697 backwards compatibility. It is equivalent to /readonly except that in
698 ACLs where /readonly is required you may specify /leaky/noupdate or
699 /strict/noupdate which are treated the same as /readonly.
700
701 A useful new feature is the /count= option. This is a generalization
702 of the per_byte option, so that you can measure the throughput of other
703 aggregate values. For example, the per_byte option is now equivalent
704 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
705
706 The per_rcpt option has been generalized using the /count= mechanism
707 (though it's more complicated than the per_byte equivalence). When it is
708 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
709 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
710 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
711 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
712 Note that using per_rcpt with a non-readonly update mode in more than
713 one ACL will cause the recipients to be double-counted. (The per_mail
714 and per_byte options don't have this problem.)
715
716 The handling of very low rates has changed slightly. If the computed rate
717 is less than the event's count (usually one) then this event is the first
718 after a long gap. In this case the rate is set to the same as this event's
719 count, so that the first message of a spam run is counted properly.
720
721 The major new feature is a mechanism for counting the rate of unique
722 events. The new per_addr option counts the number of different
723 recipients that someone has sent messages to in the last time period. It
724 behaves like per_rcpt if all the recipient addresses are different, but
725 duplicate recipient addresses do not increase the measured rate. Like
726 the /count= option this is a general mechanism, so the per_addr option
727 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
728 example, measure the rate that a client uses different sender addresses
729 with the options per_mail/unique=$sender_address. There are further
730 details in the main documentation.

811 time unintentionally subject to list matching rules, letting the header
812 cause arbitrary Exim lookups (of items which can occur in lists, *not*
813 arbitrary string expansion). This allowed for information disclosure.

1280 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1281 were called 'true' and it seems that C99 defines that as a reserved

1283 not include C99-style headers which use bools without triggering

1300-----------------
1301
1302PH/01 Another patch from the Sieve maintainer.
1303
6a3bceb1
PH
1304PH/02 When an IPv6 address is converted to a string for single-key lookup
1305 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1306 dots are used instead of colons so that keys in lsearch files need not
1307 contain colons. This was done some time before quoting was made available
1308 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1309 (notated using the quote facility) so as to distinguish them from IPv4
1310 keys. This meant that lookups for IP addresses in host lists did not work
1311 for iplsearch lookups.
1312
1313 This has been fixed by arranging for IPv6 addresses to be expressed with
1314 colons if the lookup type is iplsearch. This is not incompatible, because
1315 previously such lookups could never work.
1316
1317 The situation is now rather anomolous, since one *can* have colons in
1318 ordinary lsearch keys. However, making the change in all cases is
1319 incompatible and would probably break a number of configurations.

MH
1324MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1325 conversion specification without a maximum field width, thereby enabling
1326 a rogue spamd server to cause a buffer overflow. While nobody in their
1327 right mind would setup Exim to query an untrusted spamd server, an
1328 attacker that gains access to a server running spamd could potentially
1329 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
1334MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1335 a directory entry by the name of the lookup key. Previously, if a
1336 symlink pointed to a non-existing file or a file in a directory that
1337 Exim lacked permissions to read, a lookup for a key matching that
1338 symlink would fail. Now it is enough that a matching directory entry
1339 exists, symlink or not. (Bugzilla 503.)

1416 if a client was not listed at all, or was listed with a value other than
1417 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,

1522PH/29 SMTP synchronization checks are implemented when a command is read -
1523 there is a check that no more input is waiting when there shouldn't be
1524 any. However, for some commands, a delay in an ACL can mean that it is
1525 some time before the response is written. In this time, more input might
1526 arrive, invalidly. So now there are extra checks after an ACL has run for
1527 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1528 pipelining has not been advertised.

1540PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in

1543 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1544 was a macro that became an assignment, so it seemed to work. This has
1545 changed to a proper function call with a void return, hence the compile
1546 error. Exim's code has been fixed.

1575 whoever called Exim into the -H file. In the case of the daemon it was
1576 behaving confusingly. When first started, it used values for whoever
1577 started the daemon, but after a SIGHUP it used the Exim user (because it
1578 calls itself on a restart). I have changed the code so that it now always
1579 uses the Exim user.

1581PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
1582 message are rejected with the same error (e.g. no authentication or bad
1583 sender address), and a DATA command is nevertheless sent (as can happen
1584 with PIPELINING or a stupid MUA), the error message that was given to the
1585 RCPT commands is included in the rejection of the DATA command. This is
1586 intended to be helpful for MUAs that show only the final error to their
1587 users.

58eb016e 1601PH/44 I found a way to check for a TCP/IP connection going away before sending

PH
1602 the response to the final '.' that terminates a message, but only in the
1603 case where the client has not sent further data following the '.'
1604 (unfortunately, this is allowed). However, in many cases there won't be
1605 any further data because there won't be any more messages to send. A call
1606 to select() can be used: if it shows that the input is "ready", there is
1607 either input waiting, or the socket has been closed. An attempt to read
1608 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1609 would have sent an OK response which the client would never have see.

1617Exim version 4.66
1618-----------------
1619
1620PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1621 fixed by 4.65/MH/01 (is this a record?) are fixed:
1622
1623 (i) An empty string was always treated as zero by the numeric comparison
1624 operators. This behaviour has been restored.
1625
1626 (ii) It is documented that the numeric comparison operators always treat
1627 their arguments as decimal numbers. This was broken in that numbers
1628 starting with 0 were being interpreted as octal.
1629
1630 While fixing these problems I realized that there was another issue that
1631 hadn't been noticed. Values of message_size_limit (both the global option
1632 and the transport option) were treated as octal if they started with 0.
1633 The documentation was vague. These values are now always treated as
1634 decimal, and I will make that clear in the documentation.

1648PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1649 child addresses, Exim now panics and dies. Previously, because the count
1650 is held in a short int, deliveries were likely to be lost. As such a
1651 large number of recipients for a single message is ridiculous
1652 (performance will be very, very poor), I have chosen to impose a limit
1653 rather than extend the field.

1659TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1660 leftover -K file (the existence of which was triggered by #402).

1668
1669TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1670 in the DK code in transports.c. sendfile() is not really portable,

1676 in the field name.

PH
1678PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1679 callout verification, Exim cached a "reject" for the entire domain. This
1680 is correct for most verifications, but it is not correct for a recipient
1681 verification with use_sender or use_postmaster set, because in that case
1682 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1683 case of MAIL FROM:<> rejection from other early rejections (e.g.
1684 rejection of HELO). When verifying a recipient using a non-null MAIL
1685 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1686 Whatever the result of the callout, the value of the domain cache is
1687 left unchanged (for any other kind of callout, getting as far as trying
1688 RCPT means that the domain itself is ok).

1722PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1724 probably the interface on which it is arriving) and not to the outgoing
1725 callout (which could be using a different interface). This has been
1726 changed to use the value of the helo_data option from the smtp transport
1727 instead - this is what is used when a message is actually being sent. If
1728 there is no remote transport (possible with a router that sets up host
1729 addresses), $smtp_active_hostname is used.

7befa435 1732 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1733 (a) The code assumed that strncpy() returns a negative number on buffer
1734 overflow, which isn't the case. Replaced with Exim's string_format()
1735 function.
1736 (b) There were several signed/unsigned issues. I just did the minimum
1737 hacking in of casts. There is scope for a larger refactoring.
1738 (c) The code used strcasecmp() which is not a standard C function.
1739 Replaced with Exim's strcmpic() function.
1740 (d) The code set only $1; it now sets $auth1 as well.
1741 (e) A simple test gave the error "authentication client didn't specify
1742 service in request". It would seem that Dovecot has changed its
1743 interface. Fortunately there's a specification; I followed it and
1744 changed what the client sends and it appears to be working now.

1750 address A is aliased to B and C, where B exists and C does not. Without
1751 -v the output is "A verified" because verification stops after a
1752 successful redirection if more than one address is generated. However,
1753 with -v the child addresses are also verified. Exim was outputting "A
1754 failed to verify" and then showing the successful verification for C,
1755 with its parentage. It now outputs "B failed to verify", showing B's
1756 parentage before showing the successful verification of C.

322050c2
PH
1762PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1763 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1764 they consult the DNS. I had assumed they would set it the way they
1765 wanted; and indeed my experiments on Linux seem to show that in some
1766 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1767 To be on the safe side, however, I have now made the interface to
1768 host_find_byname() similar to host_find_bydns(), with an argument
1769 containing the DNS resolver options. The host_find_byname() function now
1770 sets these options at its start, just as host_find_bydns() does. The smtp
1771 transport options dns_qualify_single and dns_search_parents are passed to
1772 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1773 of host_find_byname() use the default settings of RES_DEFNAMES
1774 (qualify_single) but not RES_DNSRCH (search_parents).

1776PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1777 spool_read_header() do less string testing, by means of a preliminary
1778 switch on the second character of optional "-foo" lines. (This is
1779 overdue, caused by the large number of possibilities that now exist.
1780 Originally there were few.) While I was there, I also converted the
1781 str(n)cmp tests so they don't re-test the leading "-" and the first
1782 character, in the hope this might squeeze out yet more improvement.

1784PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1785 flag allowing group syntax was set by the header_syntax check but not
1786 turned off, possible causing trouble later; (2) The flag was not being
1787 set at all for the header_verify test, causing "group"-style headers to
1788 be rejected. I have now set it in this case, and also caused header_
1789 verify to ignore an empty address taken from a group. While doing this, I
1790 came across some other cases where the code for allowing group syntax
1791 while scanning a header line wasn't quite right (mostly, not resetting
1792 the flag correctly in the right place). These bugs could have caused
1793 trouble for malformed header lines. I hope it is now all correct.

PH
1795PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1796 with the "reply" argument non-NULL. The code, however (which originally
1797 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1798 but it didn't always do it. This confused somebody who was copying the
1799 code for some other use. I have removed all the tests.

PH
1801PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1802 feature that was used to support insecure browsers during the U.S. crypto
1803 embargo. It requires special client support, and Exim is probably the
1804 only MTA that supported it -- and would never use it because real RSA is
1805 always available. This code has been removed, because it had the bad
1806 effect of slowing Exim down by computing (never used) parameters for the
1807 RSA_EXPORT functionality.

1809PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1810 authenticator to fail if there's a tab character in the incoming data
1811 (there should never be unless someone is messing about, as it's supposed
1812 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1813 if the connection is using TLS or if the remote IP is the same as the
1814 local IP, and the "valid-client-cert option" if a client certificate has
1815 been verified.

1846
1847PH/30 Exim was sometimes attempting to deliver messages that had suffered
1848 address errors (4xx response to RCPT) over the same connection as other
1849 messages routed to the same hosts. Such deliveries are always "forced",
1850 so retry times are not inspected. This resulted in far too many retries
1851 for the affected addresses. The effect occurred only when there were more
1852 hosts than the hosts_max_try setting in the smtp transport when it had
1853 the 4xx errors. Those hosts that it had tried were not added to the list
1854 of hosts for which the message was waiting, so if all were tried, there
1855 was no problem. Two fixes have been applied:
1856
1857 (i) If there are any address or message errors in an SMTP delivery, none
1858 of the hosts (tried or untried) are now added to the list of hosts
1859 for which the message is waiting, so the message should not be a
1860 candidate for sending over the same connection that was used for a
1861 successful delivery of some other message. This seems entirely
1862 reasonable: after all the message is NOT "waiting for some host".
1863 This is so "obvious" that I'm not sure why it wasn't done
1864 previously. Hope I haven't missed anything, but it can't do any
1865 harm, as the worst effect is to miss an optimization.
1866
1867 (ii) If, despite (i), such a delivery is accidentally attempted, the
1868 routing retry time is respected, so at least it doesn't keep
1869 hammering the server.

1884PH/35 The error "getsockname() failed: connection reset by peer" was being
1885 written to the panic log as well as the main log, but it isn't really
1886 panic-worthy as it just means the connection died rather early on. I have
1887 removed the panic log writing for the ECONNRESET error when getsockname()
1888 fails.
1889
48c7f9e2
PH
1890PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1891 runs only) independently of the message's sender address. This meant
1892 that, if the 4xx error was in fact related to the sender, a different
1893 message to the same recipient with a different sender could confuse
1894 things. In particualar, this can happen when sending to a greylisting
1895 server, but other circumstances could also provoke similar problems.
1896 I have changed the default so that the retry time for these errors is now
1897 based a combination of the sender and recipient addresses. This change
1898 can be overridden by setting address_retry_include_sender=false in the
1899 smtp transport.

2167PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2169 Unfortunately, if there is a major crisis, such as a disk failure,
2170 tcp-wrappers gives "deny", whereas what one would like would be some
2171 kind of temporary error. A kludge has been added to help with this.
2172 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2173 554 error is used if errno is still zero or contains ENOENT (which occurs
2174 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2175 451 error is used.

2211PH/01 The code for finding all the local interface addresses on a FreeBSD
2212 system running IPv6 was broken. This may well have applied to all BSD
2213 systems, as well as to others that have similar system calls. The broken
2214 code found IPv4 interfaces correctly, but gave incorrect values for the
2215 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2216 that it would not match correctly against @[] and not recognize the IPv6
2217 addresses as local.

2260 autoreply, Exim could try to deliver to a non-existent relative file
2261 name, causing unrelated and misleading errors. What now happens is that

2280 non-existent - all you got was a failure to exec. I have made two
2281 changes:

2283 (a) Failures to set uid/gid, the current directory, or a process leader
2284 in a subprocess such as that created by queryprogram now generate
2285 suitable debugging ouput when -d is set.
2286

2289 the subprocess without attempting to change uid/gid.

2295 additional section of a DNS packet that returns MX or SRV records.
2296 Instead, it always explicitly searches for A/AAAA records. This avoids
2297 major problems that occur when a DNS server includes only records of one
2298 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2299 fixed another bug: if SRV records were looked up and the corresponding
2300 address records were *not* found in the additional section, the port
2301 values from the SRV records were lost.

2303PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2311PH/19 When calculating a retry time, Exim used to measure the "time since
2312 failure" by looking at the "first failed" field in the retry record. Now
2313 it does not use this if it is later than than the arrival time of the
2314 message. Instead it uses the arrival time. This makes for better
2315 behaviour in cases where some deliveries succeed, thus re-setting the
2316 "first failed" field. An example is a quota failure for a huge message
2317 when small messages continue to be delivered. Without this change, the
2318 "time since failure" will always be short, possible causing more frequent
2319 delivery attempts for the huge message than are intended.

PH
2416PH/42 The content-scanning code uses fopen() to create files in which to put
2417 message data. Previously it was not paying any attention to the mode of
2418 the files. Exim runs with umask(0) because the rest of the code creates
2419 files with open(), and sets the required mode explicitly. Thus, these
2420 files were ending up world-writeable. This was not a big issue, because,
2421 being within the spool directory, they were not world-accessible. I have
2422 created a function called modefopen, which takes an additional mode
2423 argument. It sets umask(777), creates the file, chmods it to the required
2424 mode, then resets the umask. All the relevant calls to fopen() in the
2425 content scanning code have been changed to use this function.

2437 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

2462
2463 (i) Exim was not creating retry information for temporary errors given
2464 for individual recipients after the DATA command when the smtp transport
2465 was used in LMTP mode. This meant that they could be retried too
2466 frequently, and not timed out correctly.
2467
2468 (ii) Exim was setting the flag that allows error details to be returned
2469 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2470 recipients that were returned after the DATA command.
2471
2472PH/53 This is related to PH/52, but is more general: for any failing address,
2473 when detailed error information was permitted to be returned to the
2474 sender, but the error was temporary, then after the final timeout, only
2475 "retry timeout exceeded" was returned. Now it returns the full error as

2546PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2547 function verify_get_ident() calls ip_connect() to connect a socket, but
2548 if the "connect()" function timed out, ip_connect() used to close the
2549 socket. However, verify_get_ident() also closes the socket later, and in
2550 between Exim writes to the log, which may get opened at this point. When
2551 the socket was closed in ip_connect(), the log could get the same file
2552 descriptor number as the socket. This naturally causes chaos. The fix is
2553 not to close the socket in ip_connect(); the socket should be closed by
2554 the function that creates it. There was only one place in the code where
2555 this was missing, in the iplookup router, which I don't think anybody now
2556 uses, but I've fixed it anyway.

2583 (3) Reset the variables that are obtained from the first argument of
2584 ${prvscheck and used in the second argument before leaving the code,
2585 because their memory is reclaimed, so using them afterwards may do
2586 silly things.

2613 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2614 not being looked up in the rDNS to get a host name, Exim was showing the
2615 IP address twice in Received: lines, even though the IP addresses were
2616 identical. For example:
2617
2618 Received: from [1.2.3.4] (helo=[1.2.3.4])
2619
2620 However, if the real host name was known, it was omitting the HELO data

2622 doesn't show the same IP address twice.

2714 addresses acquired from the DNS when checking that the found name did
2715 have the original IP as one of its addresses. Since any found IPv6
2716 addresses are likely to be in abbreviated form, the comparison could
2717 fail. Luckily, there already exists a function for doing the comparison

3017 with the definition in sysexits.h (which is #included earlier).
3018 Fortunately, Exim does not actually use EX_OK. The code used to try to
3019 preserve the sysexits.h value, by assumimg that macro definitions were
3020 scanned for macro replacements. I have been disabused of this notion,
3021 so now the code just undefines EX_OK before #including unistd.h.

3026 This seems wrong - if the receiver was accepting one byte at a time it
3027 would take for ever. The timeout is now adjusted when this happens. It
3028 doesn't have to be particularly precise.

3151PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints

3157 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3158 picked up on a user's system that detects such things. There doesn't seem
3159 to be a gcc warning option for this - only an attribute that has to be
3160 put on the function's prototype. It seems that in Fedora Core 4 they have
3161 set this on a number of new functions. No doubt there will be more in due
3162 course.

3164PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3165 specify a transport. However, if an address that was verified by such a
3166 router was the subject of a callout, Exim crashed because it tried to
3167 read the rcpt_include_affixes from the non-existent transport. Now it
3168 just assumes that the setting of that option is false. This bug was
3169 introduced by 4.51/PH/31.

3179PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3180 aren't the modern standard, and it seems that some systems' include files
3181 don't always have them. Exim was already checking for some of the newer
3182 ones like T_AAAA, and defining it itself. I've added checks for all the
3183 record types that Exim uses.

3185PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
3186 not automatically generating a new one, as it is supposed to. This
3187 prevented TLS from working. If the file did exist, but contained invalid
3188 data, a new version was generated, as expected. It was only the case of a
3189 non-existent file that was broken.

3200PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
3201 the use of a port name that isn't defined in /etc/services) occurred, the
3202 message was deferred as in a normal delivery, and thus remained on the
3203 spool, instead of being failed because of the mua_wrapper setting. This
3204 is now fixed, and I tidied up some of the mua_wrapper messages at the
3205 same time.

3236
3237PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3238 that changes the way the GnuTLS parameters are stored in the cache file.
3239 The new format can be generated externally. For backward compatibility,
3240 if the data in the cache doesn't make sense, Exim assumes it has read an
3241 old-format file, and it generates new data and writes a new file. This
3242 means that you can't go back to an older release without removing the
3243 file.
3244
3245PH/03 A redirect router that has both "unseen" and "one_time" set does not
3246 work if there are any delivery delays because "one_time" forces the
3247 parent to be marked "delivered", so its unseen clone is never tried
3248 again. For this reason, Exim now forbids the simultaneous setting of
3249 these two options.
3250
3251PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3252 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3253 entry if you want to know the details. The fix, however, neglected to
3254 consider the case when local delivery batching is involved. The test for
3255 "previously delivered" was not happening when checking to see if an
3256 address could be batched with a previous (undelivered) one; under
3257 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3258 address.

PH
3259
3260PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
3261 in its include files, and this causes problems building Exim.
3262
3263PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3264 header_syntax) but Exim was just ignoring anything given after a slash.
3265 In particular, this caused confusion with an attempt to use "verify =
3266 reverse_host_lookup/defer_ok". An error is now given when options are
3267 supplied for verify items that do not have them. (Maybe reverse_host_
3268 lookup should have a defer_ok option, but that's a different point.)
3269
3270PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3271 defined by RFC 821) to 2048, because there were problems with some AUTH
3272 commands, and RFC 1869 says the size should be increased for extended
3273 SMTP commands that take arguments.

3306 where they are NOT allowed) were getting very unwieldy; rewrote them as a

3320PH/19 When an Exim process that is running as root has to create an Exim log
3321 file, it does so in a subprocess that runs as exim:exim so as to get the
3322 ownership right at creation (otherwise, other Exim processes might see
3323 the file with the wrong ownership). There was no test for failure of this
3324 fork() call, which would lead to the process getting stuck as it waited
3325 for a non-existent subprocess. Forks do occasionally fail when resources
3326 run out. I reviewed all the other calls to fork(); they all seem to check
3327 for failure.

3329PH/20 When checking for unexpected SMTP input at connect time (before writing
3330 the banner), Exim was not dealing correctly with a non-positive return
3331 from the read() function. If the client had disconnected by this time,
3332 the result was a log entry for a synchronization error with an empty
3333 string after "input=" when read() returned zero. If read() returned -1
3334 (an event I could not check), uninitialized data bytes were printed.
