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

18 function when detected.

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.
46

47JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
48 size buffer was used, resulting in syntax errors when an expansion
49 exceeded it.

54JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
55 is EXPERIMENTAL_EVENT, the main-configuration and transport options
56 both become "event_action", the variables become $event_name, $event_data
aec45841 57 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
58 routers, transports and related events. The tls:cert event is now also
59 raised for inbound connections, if the main configuration event_action
60 option is defined.

107-----------------
108
109TF/01 Correctly close the server side of TLS when forking for delivery.
110
111 When a message was received over SMTP with TLS, Exim failed to clear up
112 the incoming connection properly after forking off the child process to
113 deliver the message. In some situations the subsequent outgoing
114 delivery connection happened to have the same fd number as the incoming
115 connection previously had. Exim would try to use TLS and fail, logging
116 a "Bad file descriptor" error.

362TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
363
364 When a queue runner is handling a message, Exim first routes the
365 recipient addresses, during which it prunes them based on the retry
366 hints database. After that it attempts to deliver the message to
367 any remaining recipients. It then updates the hints database using
368 the retry rules.
369
370 So if a recipient address works intermittently, it can get repeatedly
371 deferred at routing time. The retry hints record remains fresh so the
372 address never reaches the final cutoff time.
373
374 This is a fairly common occurrence when a user is bumping up against
375 their storage quota. Exim had some logic in its local delivery code
376 to deal with this. However it did not apply to per-recipient defers
377 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
378
1ddeb334
TF
379 This change adds a proper retry rule check during routing so that the
380 final cutoff time is checked against the message's age. We only do
381 this check if there is an address retry record and there is not a
382 domain retry record; this implies that previous attempts to handle
383 the address had the retry_use_local_parts option turned on. We use
384 this as an approximation for the destination being like a local
385 delivery, as in LMTP.
67bd1ab3
TF
386
387 I suspect this new check makes the old local delivery cutoff check
388 redundant, but I have not verified this so I left the code in place.

395
396 When I ran the test suite under the user fanf2, Exim expanded
397 the header to contain my full name, whereas it should have added
398 a Resent-Sender: header. It erroneously treats any prefix of the
399 username as equal to the username.

422JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
423 Server implementation by Todd Lyons, client by JH.
424 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
425 config variable "prdr_enable" controls whether the server
426 advertises the facility. If the client requests PRDR a new
427 acl_data_smtp_prdr ACL is called once for each recipient, after
428 the body content is received and before the acl_smtp_data ACL.
429 The client is controlled by bolth of: a hosts_try_prdr option
430 on the smtp transport, and the server advertisement.
431 Default client logging of deliveries and rejections involving
432 PRDR are flagged with the string "PRDR".

710TF/03 Make the exiwhat support code safe for signals. Previously Exim might
711 lock up or crash if it happened to be inside a call to libc when it
712 got a SIGUSR1 from exiwhat.
713
714 The SIGUSR1 handler appends the current process status to the process
715 log which is later printed by exiwhat. It used to use the general
716 purpose logging code to do this, but several functions it calls are
717 not safe for signals.
718
719 The new output code in the SIGUSR1 handler is specific to the process
720 log, and simple enough that it's easy to inspect for signal safety.
721 Removing some special cases also simplifies the general logging code.
722 Removing the spurious timestamps from the process log simplifies
723 exiwhat.
724
c99ce5c9
TF
725TF/04 Improved ratelimit ACL condition.
726
727 The /noupdate option has been deprecated in favour of /readonly which
728 has clearer semantics. The /leaky, /strict, and /readonly update modes
729 are mutually exclusive. The update mode is no longer included in the
730 database key; it just determines when the database is updated. (This
731 means that when you upgrde Exim will forget old rate measurements.)
732
733 Exim now checks that the per_* options are used with an update mode that
734 makes sense for the current ACL. For example, when Exim is processing a
735 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
736 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
737 must specify per_mail/readonly. If you omit the update mode it defaults to
738 /leaky where that makes sense (as before) or /readonly where required.
739
740 The /noupdate option is now undocumented but still supported for
741 backwards compatibility. It is equivalent to /readonly except that in
742 ACLs where /readonly is required you may specify /leaky/noupdate or
743 /strict/noupdate which are treated the same as /readonly.
744
745 A useful new feature is the /count= option. This is a generalization
746 of the per_byte option, so that you can measure the throughput of other
747 aggregate values. For example, the per_byte option is now equivalent
748 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
749
750 The per_rcpt option has been generalized using the /count= mechanism
751 (though it's more complicated than the per_byte equivalence). When it is
752 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
753 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
754 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
755 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
756 Note that using per_rcpt with a non-readonly update mode in more than
757 one ACL will cause the recipients to be double-counted. (The per_mail
758 and per_byte options don't have this problem.)
759
760 The handling of very low rates has changed slightly. If the computed rate
761 is less than the event's count (usually one) then this event is the first
762 after a long gap. In this case the rate is set to the same as this event's
763 count, so that the first message of a spam run is counted properly.
764
765 The major new feature is a mechanism for counting the rate of unique
766 events. The new per_addr option counts the number of different
767 recipients that someone has sent messages to in the last time period. It
768 behaves like per_rcpt if all the recipient addresses are different, but
769 duplicate recipient addresses do not increase the measured rate. Like
770 the /count= option this is a general mechanism, so the per_addr option
771 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
772 example, measure the rate that a client uses different sender addresses
773 with the options per_mail/unique=$sender_address. There are further
774 details in the main documentation.

1325 were called 'true' and it seems that C99 defines that as a reserved

1346PH/01 Another patch from the Sieve maintainer.
1347
6a3bceb1
PH
1348PH/02 When an IPv6 address is converted to a string for single-key lookup
1349 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1350 dots are used instead of colons so that keys in lsearch files need not
1351 contain colons. This was done some time before quoting was made available
1352 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1353 (notated using the quote facility) so as to distinguish them from IPv4
1354 keys. This meant that lookups for IP addresses in host lists did not work
1355 for iplsearch lookups.
1356
1357 This has been fixed by arranging for IPv6 addresses to be expressed with
1358 colons if the lookup type is iplsearch. This is not incompatible, because
1359 previously such lookups could never work.
1360
1361 The situation is now rather anomolous, since one *can* have colons in
1362 ordinary lsearch keys. However, making the change in all cases is
1363 incompatible and would probably break a number of configurations.

MH
1368MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1369 conversion specification without a maximum field width, thereby enabling
1370 a rogue spamd server to cause a buffer overflow. While nobody in their
1371 right mind would setup Exim to query an untrusted spamd server, an
1372 attacker that gains access to a server running spamd could potentially
1373 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1378MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1379 a directory entry by the name of the lookup key. Previously, if a
1380 symlink pointed to a non-existing file or a file in a directory that
1381 Exim lacked permissions to read, a lookup for a key matching that
1382 symlink would fail. Now it is enough that a matching directory entry
1383 exists, symlink or not. (Bugzilla 503.)

1460 if a client was not listed at all, or was listed with a value other than

1566PH/29 SMTP synchronization checks are implemented when a command is read -
1567 there is a check that no more input is waiting when there shouldn't be

1569 some time before the response is written. In this time, more input might
1570 arrive, invalidly. So now there are extra checks after an ACL has run for
1571 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1572 pipelining has not been advertised.

1587 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1588 was a macro that became an assignment, so it seemed to work. This has
1589 changed to a proper function call with a void return, hence the compile

1646 the response to the final '.' that terminates a message, but only in the
1647 case where the client has not sent further data following the '.'
1648 (unfortunately, this is allowed). However, in many cases there won't be
1649 any further data because there won't be any more messages to send. A call
1650 to select() can be used: if it shows that the input is "ready", there is
1651 either input waiting, or the socket has been closed. An attempt to read
1652 the next input character can distinguish the two cases. Previously, Exim

1663
1664PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1665 fixed by 4.65/MH/01 (is this a record?) are fixed:
1666
1667 (i) An empty string was always treated as zero by the numeric comparison
1668 operators. This behaviour has been restored.
1669
1670 (ii) It is documented that the numeric comparison operators always treat
1671 their arguments as decimal numbers. This was broken in that numbers
1672 starting with 0 were being interpreted as octal.
1673
1674 While fixing these problems I realized that there was another issue that
1675 hadn't been noticed. Values of message_size_limit (both the global option
1676 and the transport option) were treated as octal if they started with 0.
1677 The documentation was vague. These values are now always treated as
1678 decimal, and I will make that clear in the documentation.

1695 large number of recipients for a single message is ridiculous
1696 (performance will be very, very poor), I have chosen to impose a limit
1697 rather than extend the field.

PH
1722PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1723 callout verification, Exim cached a "reject" for the entire domain. This
1724 is correct for most verifications, but it is not correct for a recipient
1725 verification with use_sender or use_postmaster set, because in that case
1726 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1727 case of MAIL FROM:<> rejection from other early rejections (e.g.
1728 rejection of HELO). When verifying a recipient using a non-null MAIL
1729 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1730 Whatever the result of the callout, the value of the domain cache is
1731 left unchanged (for any other kind of callout, getting as far as trying
1732 RCPT means that the domain itself is ok).

1768 probably the interface on which it is arriving) and not to the outgoing
1769 callout (which could be using a different interface). This has been
1770 changed to use the value of the helo_data option from the smtp transport
1771 instead - this is what is used when a message is actually being sent. If
1772 there is no remote transport (possible with a router that sets up host
1773 addresses), $smtp_active_hostname is used.

14aa5a05
PH
1777 (a) The code assumed that strncpy() returns a negative number on buffer
1778 overflow, which isn't the case. Replaced with Exim's string_format()
1779 function.
1780 (b) There were several signed/unsigned issues. I just did the minimum
1781 hacking in of casts. There is scope for a larger refactoring.
1782 (c) The code used strcasecmp() which is not a standard C function.
1783 Replaced with Exim's strcmpic() function.
1784 (d) The code set only $1; it now sets $auth1 as well.
1785 (e) A simple test gave the error "authentication client didn't specify
1786 service in request". It would seem that Dovecot has changed its
1787 interface. Fortunately there's a specification; I followed it and
1788 changed what the client sends and it appears to be working now.

1794 address A is aliased to B and C, where B exists and C does not. Without
1795 -v the output is "A verified" because verification stops after a
1796 successful redirection if more than one address is generated. However,
1797 with -v the child addresses are also verified. Exim was outputting "A
1798 failed to verify" and then showing the successful verification for C,
1799 with its parentage. It now outputs "B failed to verify", showing B's
1800 parentage before showing the successful verification of C.

PH
1806PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1807 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1808 they consult the DNS. I had assumed they would set it the way they
1809 wanted; and indeed my experiments on Linux seem to show that in some
1810 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1811 To be on the safe side, however, I have now made the interface to
1812 host_find_byname() similar to host_find_bydns(), with an argument
1813 containing the DNS resolver options. The host_find_byname() function now
1814 sets these options at its start, just as host_find_bydns() does. The smtp
1815 transport options dns_qualify_single and dns_search_parents are passed to
1816 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1817 of host_find_byname() use the default settings of RES_DEFNAMES
1818 (qualify_single) but not RES_DNSRCH (search_parents).

1820PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1821 spool_read_header() do less string testing, by means of a preliminary
1822 switch on the second character of optional "-foo" lines. (This is
1823 overdue, caused by the large number of possibilities that now exist.
1824 Originally there were few.) While I was there, I also converted the
1825 str(n)cmp tests so they don't re-test the leading "-" and the first
1826 character, in the hope this might squeeze out yet more improvement.

1828PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1829 flag allowing group syntax was set by the header_syntax check but not
1830 turned off, possible causing trouble later; (2) The flag was not being
1831 set at all for the header_verify test, causing "group"-style headers to
1832 be rejected. I have now set it in this case, and also caused header_
1833 verify to ignore an empty address taken from a group. While doing this, I
1834 came across some other cases where the code for allowing group syntax
1835 while scanning a header line wasn't quite right (mostly, not resetting
1836 the flag correctly in the right place). These bugs could have caused
1837 trouble for malformed header lines. I hope it is now all correct.

PH
1839PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1840 with the "reply" argument non-NULL. The code, however (which originally
1841 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1842 but it didn't always do it. This confused somebody who was copying the
1843 code for some other use. I have removed all the tests.

PH
1845PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1846 feature that was used to support insecure browsers during the U.S. crypto
1847 embargo. It requires special client support, and Exim is probably the
1848 only MTA that supported it -- and would never use it because real RSA is
1849 always available. This code has been removed, because it had the bad
1850 effect of slowing Exim down by computing (never used) parameters for the
1851 RSA_EXPORT functionality.

1856 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1857 if the connection is using TLS or if the remote IP is the same as the
1858 local IP, and the "valid-client-cert option" if a client certificate has
1859 been verified.

1890
1891PH/30 Exim was sometimes attempting to deliver messages that had suffered
1892 address errors (4xx response to RCPT) over the same connection as other
1893 messages routed to the same hosts. Such deliveries are always "forced",
1894 so retry times are not inspected. This resulted in far too many retries
1895 for the affected addresses. The effect occurred only when there were more
1896 hosts than the hosts_max_try setting in the smtp transport when it had
1897 the 4xx errors. Those hosts that it had tried were not added to the list
1898 of hosts for which the message was waiting, so if all were tried, there
1899 was no problem. Two fixes have been applied:
1900
1901 (i) If there are any address or message errors in an SMTP delivery, none
1902 of the hosts (tried or untried) are now added to the list of hosts
1903 for which the message is waiting, so the message should not be a
1904 candidate for sending over the same connection that was used for a
1905 successful delivery of some other message. This seems entirely
1906 reasonable: after all the message is NOT "waiting for some host".
1907 This is so "obvious" that I'm not sure why it wasn't done
1908 previously. Hope I haven't missed anything, but it can't do any
1909 harm, as the worst effect is to miss an optimization.
1910
1911 (ii) If, despite (i), such a delivery is accidentally attempted, the
1912 routing retry time is respected, so at least it doesn't keep
1913 hammering the server.

1928PH/35 The error "getsockname() failed: connection reset by peer" was being
1929 written to the panic log as well as the main log, but it isn't really

1931 removed the panic log writing for the ECONNRESET error when getsockname()
1932 fails.

48c7f9e2
PH
1934PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1935 runs only) independently of the message's sender address. This meant
1936 that, if the 4xx error was in fact related to the sender, a different
1937 message to the same recipient with a different sender could confuse
1938 things. In particualar, this can happen when sending to a greylisting
1939 server, but other circumstances could also provoke similar problems.
1940 I have changed the default so that the retry time for these errors is now
1941 based a combination of the sender and recipient addresses. This change
1942 can be overridden by setting address_retry_include_sender=false in the
1943 smtp transport.

2211PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2213 Unfortunately, if there is a major crisis, such as a disk failure,
2214 tcp-wrappers gives "deny", whereas what one would like would be some
2215 kind of temporary error. A kludge has been added to help with this.
2216 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2217 554 error is used if errno is still zero or contains ENOENT (which occurs
2218 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2219 451 error is used.

2258 code found IPv4 interfaces correctly, but gave incorrect values for the
2259 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was

2304 autoreply, Exim could try to deliver to a non-existent relative file

2341 major problems that occur when a DNS server includes only records of one
2342 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2343 fixed another bug: if SRV records were looked up and the corresponding
2344 address records were *not* found in the additional section, the port
2345 values from the SRV records were lost.

2355PH/19 When calculating a retry time, Exim used to measure the "time since
2356 failure" by looking at the "first failed" field in the retry record. Now
2357 it does not use this if it is later than than the arrival time of the
2358 message. Instead it uses the arrival time. This makes for better
2359 behaviour in cases where some deliveries succeed, thus re-setting the
2360 "first failed" field. An example is a quota failure for a huge message
2361 when small messages continue to be delivered. Without this change, the
2362 "time since failure" will always be short, possible causing more frequent
2363 delivery attempts for the huge message than are intended.

PH
2460PH/42 The content-scanning code uses fopen() to create files in which to put
2461 message data. Previously it was not paying any attention to the mode of
2462 the files. Exim runs with umask(0) because the rest of the code creates
2463 files with open(), and sets the required mode explicitly. Thus, these
2464 files were ending up world-writeable. This was not a big issue, because,
2465 being within the spool directory, they were not world-accessible. I have
2466 created a function called modefopen, which takes an additional mode
2467 argument. It sets umask(777), creates the file, chmods it to the required
2468 mode, then resets the umask. All the relevant calls to fopen() in the
2469 content scanning code have been changed to use this function.

2481 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

2504PH/52 Two bugs concerned with error handling when the smtp transport is
2505 used in LMTP mode:
2506
2507 (i) Exim was not creating retry information for temporary errors given
2508 for individual recipients after the DATA command when the smtp transport
2509 was used in LMTP mode. This meant that they could be retried too
2510 frequently, and not timed out correctly.
2511
2512 (ii) Exim was setting the flag that allows error details to be returned
2513 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2514 recipients that were returned after the DATA command.
2515
2516PH/53 This is related to PH/52, but is more general: for any failing address,
2517 when detailed error information was permitted to be returned to the
2518 sender, but the error was temporary, then after the final timeout, only
2519 "retry timeout exceeded" was returned. Now it returns the full error as

2590PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2591 function verify_get_ident() calls ip_connect() to connect a socket, but
2592 if the "connect()" function timed out, ip_connect() used to close the
2593 socket. However, verify_get_ident() also closes the socket later, and in
2594 between Exim writes to the log, which may get opened at this point. When
2595 the socket was closed in ip_connect(), the log could get the same file
2596 descriptor number as the socket. This naturally causes chaos. The fix is
2597 not to close the socket in ip_connect(); the socket should be closed by
2598 the function that creates it. There was only one place in the code where
2599 this was missing, in the iplookup router, which I don't think anybody now
2600 uses, but I've fixed it anyway.

2660 identical. For example:
2661
2662 Received: from [1.2.3.4] (helo=[1.2.3.4])
2663

2758 addresses acquired from the DNS when checking that the found name did
2759 have the original IP as one of its addresses. Since any found IPv6
2760 addresses are likely to be in abbreviated form, the comparison could
2761 fail. Luckily, there already exists a function for doing the comparison
2762 by converting both addresses to binary, so now that is used instead of
2763 the text comparison.

PH
2765PH/20 There was another similar case to PH/19, when a complete host name was
2766 given in a host list; looking up its IP address could give an abbreviated
2767 form, whereas the current host's name might or might not be abbreviated.
2768 The same fix has been applied.

3151 with no configuration file to get the compiled in version, before it
3152 falls back to the previous guessing code."

3169 and a new error check for 8bit text in MIME parts. Comparator and

3171 extension, but it is not well tested yet (read: it works for me)."

3195PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints

3201 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3202 picked up on a user's system that detects such things. There doesn't seem
3203 to be a gcc warning option for this - only an attribute that has to be
3204 put on the function's prototype. It seems that in Fedora Core 4 they have
3205 set this on a number of new functions. No doubt there will be more in due
3206 course.

PH
3208PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3209 specify a transport. However, if an address that was verified by such a
3210 router was the subject of a callout, Exim crashed because it tried to
3211 read the rcpt_include_affixes from the non-existent transport. Now it
3212 just assumes that the setting of that option is false. This bug was
3213 introduced by 4.51/PH/31.

3223PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3224 aren't the modern standard, and it seems that some systems' include files
3225 don't always have them. Exim was already checking for some of the newer
3226 ones like T_AAAA, and defining it itself. I've added checks for all the
3227 record types that Exim uses.

3229PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
3230 not automatically generating a new one, as it is supposed to. This
3231 prevented TLS from working. If the file did exist, but contained invalid
3232 data, a new version was generated, as expected. It was only the case of a
3233 non-existent file that was broken.

3244PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
3245 the use of a port name that isn't defined in /etc/services) occurred, the
3246 message was deferred as in a normal delivery, and thus remained on the
3247 spool, instead of being failed because of the mua_wrapper setting. This
3248 is now fixed, and I tidied up some of the mua_wrapper messages at the
3249 same time.

3251SC/08 Eximstats: whilst parsing the mainlog(s), store information about

3280
3281PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3282 that changes the way the GnuTLS parameters are stored in the cache file.
3283 The new format can be generated externally. For backward compatibility,
3284 if the data in the cache doesn't make sense, Exim assumes it has read an
3285 old-format file, and it generates new data and writes a new file. This
3286 means that you can't go back to an older release without removing the
3287 file.
3288
3289PH/03 A redirect router that has both "unseen" and "one_time" set does not
3290 work if there are any delivery delays because "one_time" forces the
3291 parent to be marked "delivered", so its unseen clone is never tried
3292 again. For this reason, Exim now forbids the simultaneous setting of
3293 these two options.
3294
3295PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3296 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3297 entry if you want to know the details. The fix, however, neglected to
3298 consider the case when local delivery batching is involved. The test for
3299 "previously delivered" was not happening when checking to see if an
3300 address could be batched with a previous (undelivered) one; under
3301 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3302 address.

PH
3303
3304PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
3305 in its include files, and this causes problems building Exim.
3306
3307PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3308 header_syntax) but Exim was just ignoring anything given after a slash.
3309 In particular, this caused confusion with an attempt to use "verify =
3310 reverse_host_lookup/defer_ok". An error is now given when options are
3311 supplied for verify items that do not have them. (Maybe reverse_host_
3312 lookup should have a defer_ok option, but that's a different point.)
3313
3314PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3315 defined by RFC 821) to 2048, because there were problems with some AUTH
3316 commands, and RFC 1869 says the size should be increased for extended
3317 SMTP commands that take arguments.
