TF
99TF/03 Make the exiwhat support code safe for signals. Previously Exim might
100 lock up or crash if it happened to be inside a call to libc when it
101 got a SIGUSR1 from exiwhat.
102
103 The SIGUSR1 handler appends the current process status to the process
104 log which is later printed by exiwhat. It used to use the general
105 purpose logging code to do this, but several functions it calls are
106 not safe for signals.
107
108 The new output code in the SIGUSR1 handler is specific to the process
109 log, and simple enough that it's easy to inspect for signal safety.
110 Removing some special cases also simplifies the general logging code.
111 Removing the spurious timestamps from the process log simplifies
112 exiwhat.

TF
114TF/04 Improved ratelimit ACL condition.
115
116 The /noupdate option has been deprecated in favour of /readonly which
117 has clearer semantics. The /leaky, /strict, and /readonly update modes
118 are mutually exclusive. The update mode is no longer included in the
119 database key; it just determines when the database is updated. (This
120 means that when you upgrde Exim will forget old rate measurements.)
121
122 Exim now checks that the per_* options are used with an update mode that
123 makes sense for the current ACL. For example, when Exim is processing a
124 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
125 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
126 must specify per_mail/readonly. If you omit the update mode it defaults to
127 /leaky where that makes sense (as before) or /readonly where required.
128
129 The /noupdate option is now undocumented but still supported for
130 backwards compatibility. It is equivalent to /readonly except that in
131 ACLs where /readonly is required you may specify /leaky/noupdate or
132 /strict/noupdate which are treated the same as /readonly.
133
134 A useful new feature is the /count= option. This is a generalization
135 of the per_byte option, so that you can measure the throughput of other
136 aggregate values. For example, the per_byte option is now equivalent
137 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
138
139 The per_rcpt option has been generalized using the /count= mechanism
140 (though it's more complicated than the per_byte equivalence). When it is
141 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
142 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
143 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
144 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
145 Note that using per_rcpt with a non-readonly update mode in more than
146 one ACL will cause the recipients to be double-counted. (The per_mail
147 and per_byte options don't have this problem.)
148
149 The handling of very low rates has changed slightly. If the computed rate
150 is less than the event's count (usually one) then this event is the first
151 after a long gap. In this case the rate is set to the same as this event's
152 count, so that the first message of a spam run is counted properly.
153
154 The major new feature is a mechanism for counting the rate of unique
155 events. The new per_addr option counts the number of different
156 recipients that someone has sent messages to in the last time period. It
157 behaves like per_rcpt if all the recipient addresses are different, but
158 duplicate recipient addresses do not increase the measured rate. Like
159 the /count= option this is a general mechanism, so the per_addr option
160 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
161 example, measure the rate that a client uses different sender addresses
162 with the options per_mail/unique=$sender_address. There are further
163 details in the main documentation.

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

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

735PH/01 Another patch from the Sieve maintainer.
736
6a3bceb1
PH
737PH/02 When an IPv6 address is converted to a string for single-key lookup
738 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
739 dots are used instead of colons so that keys in lsearch files need not
740 contain colons. This was done some time before quoting was made available
741 in lsearch files. However, iplsearch files do require colons in IPv6 keys
742 (notated using the quote facility) so as to distinguish them from IPv4
743 keys. This meant that lookups for IP addresses in host lists did not work
744 for iplsearch lookups.
745
746 This has been fixed by arranging for IPv6 addresses to be expressed with
747 colons if the lookup type is iplsearch. This is not incompatible, because
748 previously such lookups could never work.
749
750 The situation is now rather anomolous, since one *can* have colons in
751 ordinary lsearch keys. However, making the change in all cases is
752 incompatible and would probably break a number of configurations.

757MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
758 conversion specification without a maximum field width, thereby enabling
759 a rogue spamd server to cause a buffer overflow. While nobody in their
760 right mind would setup Exim to query an untrusted spamd server, an
761 attacker that gains access to a server running spamd could potentially
762 exploit this vulnerability to run arbitrary code as the Exim user.

MH
767MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
768 a directory entry by the name of the lookup key. Previously, if a
769 symlink pointed to a non-existing file or a file in a directory that
770 Exim lacked permissions to read, a lookup for a key matching that
771 symlink would fail. Now it is enough that a matching directory entry
772 exists, symlink or not. (Bugzilla 503.)

955PH/29 SMTP synchronization checks are implemented when a command is read -
956 there is a check that no more input is waiting when there shouldn't be

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

1035 the response to the final '.' that terminates a message, but only in the
1036 case where the client has not sent further data following the '.'
1037 (unfortunately, this is allowed). However, in many cases there won't be
1038 any further data because there won't be any more messages to send. A call
1039 to select() can be used: if it shows that the input is "ready", there is
1040 either input waiting, or the socket has been closed. An attempt to read
1041 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1042 would have sent an OK response which the client would never have see.

1053PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1054 fixed by 4.65/MH/01 (is this a record?) are fixed:
1055
1056 (i) An empty string was always treated as zero by the numeric comparison
1057 operators. This behaviour has been restored.
1058
1059 (ii) It is documented that the numeric comparison operators always treat
1060 their arguments as decimal numbers. This was broken in that numbers
1061 starting with 0 were being interpreted as octal.
1062
1063 While fixing these problems I realized that there was another issue that
1064 hadn't been noticed. Values of message_size_limit (both the global option
1065 and the transport option) were treated as octal if they started with 0.
1066 The documentation was vague. These values are now always treated as
1067 decimal, and I will make that clear in the documentation.

1084 large number of recipients for a single message is ridiculous

PH
1111PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1112 callout verification, Exim cached a "reject" for the entire domain. This
1113 is correct for most verifications, but it is not correct for a recipient
1114 verification with use_sender or use_postmaster set, because in that case
1115 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1116 case of MAIL FROM:<> rejection from other early rejections (e.g.
1117 rejection of HELO). When verifying a recipient using a non-null MAIL
1118 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1119 Whatever the result of the callout, the value of the domain cache is
1120 left unchanged (for any other kind of callout, getting as far as trying
1121 RCPT means that the domain itself is ok).

1157 probably the interface on which it is arriving) and not to the outgoing
1158 callout (which could be using a different interface). This has been
1159 changed to use the value of the helo_data option from the smtp transport
1160 instead - this is what is used when a message is actually being sent. If
1161 there is no remote transport (possible with a router that sets up host

7befa435 1165 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1166 (a) The code assumed that strncpy() returns a negative number on buffer
1167 overflow, which isn't the case. Replaced with Exim's string_format()
1168 function.
1169 (b) There were several signed/unsigned issues. I just did the minimum
1170 hacking in of casts. There is scope for a larger refactoring.
1171 (c) The code used strcasecmp() which is not a standard C function.
1172 Replaced with Exim's strcmpic() function.
1173 (d) The code set only $1; it now sets $auth1 as well.
1174 (e) A simple test gave the error "authentication client didn't specify
1175 service in request". It would seem that Dovecot has changed its
1176 interface. Fortunately there's a specification; I followed it and
1177 changed what the client sends and it appears to be working now.

1184 -v the output is "A verified" because verification stops after a
1185 successful redirection if more than one address is generated. However,
1186 with -v the child addresses are also verified. Exim was outputting "A
1187 failed to verify" and then showing the successful verification for C,
1188 with its parentage. It now outputs "B failed to verify", showing B's
1189 parentage before showing the successful verification of C.

1199 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1200 To be on the safe side, however, I have now made the interface to
1201 host_find_byname() similar to host_find_bydns(), with an argument
1202 containing the DNS resolver options. The host_find_byname() function now
1203 sets these options at its start, just as host_find_bydns() does. The smtp
1204 transport options dns_qualify_single and dns_search_parents are passed to
1205 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1206 of host_find_byname() use the default settings of RES_DEFNAMES
1207 (qualify_single) but not RES_DNSRCH (search_parents).

1209PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1210 spool_read_header() do less string testing, by means of a preliminary
1211 switch on the second character of optional "-foo" lines. (This is
1212 overdue, caused by the large number of possibilities that now exist.
1213 Originally there were few.) While I was there, I also converted the
1214 str(n)cmp tests so they don't re-test the leading "-" and the first
1215 character, in the hope this might squeeze out yet more improvement.

1217PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1218 flag allowing group syntax was set by the header_syntax check but not
1219 turned off, possible causing trouble later; (2) The flag was not being
1220 set at all for the header_verify test, causing "group"-style headers to
1221 be rejected. I have now set it in this case, and also caused header_
1222 verify to ignore an empty address taken from a group. While doing this, I
1223 came across some other cases where the code for allowing group syntax
1224 while scanning a header line wasn't quite right (mostly, not resetting
1225 the flag correctly in the right place). These bugs could have caused
1226 trouble for malformed header lines. I hope it is now all correct.

1228PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1229 with the "reply" argument non-NULL. The code, however (which originally
1230 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1231 but it didn't always do it. This confused somebody who was copying the
1232 code for some other use. I have removed all the tests.

PH
1234PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1235 feature that was used to support insecure browsers during the U.S. crypto
1236 embargo. It requires special client support, and Exim is probably the
1237 only MTA that supported it -- and would never use it because real RSA is
1238 always available. This code has been removed, because it had the bad
1239 effect of slowing Exim down by computing (never used) parameters for the
1240 RSA_EXPORT functionality.

1242PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1243 authenticator to fail if there's a tab character in the incoming data

1245 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1246 if the connection is using TLS or if the remote IP is the same as the
1247 local IP, and the "valid-client-cert option" if a client certificate has
1248 been verified.

1279
1280PH/30 Exim was sometimes attempting to deliver messages that had suffered
1281 address errors (4xx response to RCPT) over the same connection as other
1282 messages routed to the same hosts. Such deliveries are always "forced",
1283 so retry times are not inspected. This resulted in far too many retries
1284 for the affected addresses. The effect occurred only when there were more
1285 hosts than the hosts_max_try setting in the smtp transport when it had
1286 the 4xx errors. Those hosts that it had tried were not added to the list
1287 of hosts for which the message was waiting, so if all were tried, there
1288 was no problem. Two fixes have been applied:
1289
1290 (i) If there are any address or message errors in an SMTP delivery, none
1291 of the hosts (tried or untried) are now added to the list of hosts
1292 for which the message is waiting, so the message should not be a
1293 candidate for sending over the same connection that was used for a
1294 successful delivery of some other message. This seems entirely
1295 reasonable: after all the message is NOT "waiting for some host".
1296 This is so "obvious" that I'm not sure why it wasn't done
1297 previously. Hope I haven't missed anything, but it can't do any
1298 harm, as the worst effect is to miss an optimization.
1299
1300 (ii) If, despite (i), such a delivery is accidentally attempted, the
1301 routing retry time is respected, so at least it doesn't keep
1302 hammering the server.

1317PH/35 The error "getsockname() failed: connection reset by peer" was being
1318 written to the panic log as well as the main log, but it isn't really
1319 panic-worthy as it just means the connection died rather early on. I have
1320 removed the panic log writing for the ECONNRESET error when getsockname()
1321 fails.
1322
48c7f9e2
PH
1323PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1324 runs only) independently of the message's sender address. This meant
1325 that, if the 4xx error was in fact related to the sender, a different
1326 message to the same recipient with a different sender could confuse
1327 things. In particualar, this can happen when sending to a greylisting
1328 server, but other circumstances could also provoke similar problems.
1329 I have changed the default so that the retry time for these errors is now
1330 based a combination of the sender and recipient addresses. This change
1331 can be overridden by setting address_retry_include_sender=false in the
1332 smtp transport.

1585 However, an attempt to turn on case-sensitivity in a regex key by
1586 including (?-i) didn't work because the subject string was already
1587 lowercased, and the effects were non-intuitive. It turns out that a
1588 one-line patch can be used to allow (?-i) to work as expected.

1600PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
1601 "Deny" causes Exim to reject the incoming connection with a 554 error.
1602 Unfortunately, if there is a major crisis, such as a disk failure,
1603 tcp-wrappers gives "deny", whereas what one would like would be some
1604 kind of temporary error. A kludge has been added to help with this.
1605 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1606 554 error is used if errno is still zero or contains ENOENT (which occurs
1607 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1608 451 error is used.

1630PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
1631 folder from quota calculations, a direct delivery into this folder messed
1632 up the contents of the maildirsize file. This was because the regex was
1633 used only to exclude .Trash (or whatever) when the size of the mailbox
1634 was calculated. There was no check that a delivery was happening into an
1635 excluded directory. This bug has been fixed by ignoring all quota

1642-----------------
1643
1644PH/01 The code for finding all the local interface addresses on a FreeBSD
1645 system running IPv6 was broken. This may well have applied to all BSD
1646 systems, as well as to others that have similar system calls. The broken
1647 code found IPv4 interfaces correctly, but gave incorrect values for the
1648 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1649 that it would not match correctly against @[] and not recognize the IPv6
1650 addresses as local.

1691 syntactically invalid From: or Reply-to: line, and a filter used this to
1692 generate an autoreply, and therefore failed to obtain an address for the
1693 autoreply, Exim could try to deliver to a non-existent relative file
1694 name, causing unrelated and misleading errors. What now happens is that
1695 it logs this as a hard delivery error, but does not attempt to create a

1713 non-existent - all you got was a failure to exec. I have made two
1714 changes:
1715
1716 (a) Failures to set uid/gid, the current directory, or a process leader
1717 in a subprocess such as that created by queryprogram now generate
1718 suitable debugging ouput when -d is set.
1719
1720 (b) The queryprogram router detects when it is not running as root,

1722 the subprocess without attempting to change uid/gid.

1727PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1728 additional section of a DNS packet that returns MX or SRV records.
1729 Instead, it always explicitly searches for A/AAAA records. This avoids
1730 major problems that occur when a DNS server includes only records of one
1731 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1732 fixed another bug: if SRV records were looked up and the corresponding
1733 address records were *not* found in the additional section, the port
1734 values from the SRV records were lost.

1736PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

1743
727071f8
PH
1744PH/19 When calculating a retry time, Exim used to measure the "time since
1745 failure" by looking at the "first failed" field in the retry record. Now
1746 it does not use this if it is later than than the arrival time of the
1747 message. Instead it uses the arrival time. This makes for better
1748 behaviour in cases where some deliveries succeed, thus re-setting the
1749 "first failed" field. An example is a quota failure for a huge message
1750 when small messages continue to be delivered. Without this change, the
1751 "time since failure" will always be short, possible causing more frequent
1752 delivery attempts for the huge message than are intended.

PH
1849PH/42 The content-scanning code uses fopen() to create files in which to put
1850 message data. Previously it was not paying any attention to the mode of
1851 the files. Exim runs with umask(0) because the rest of the code creates
1852 files with open(), and sets the required mode explicitly. Thus, these
1853 files were ending up world-writeable. This was not a big issue, because,
1854 being within the spool directory, they were not world-accessible. I have
1855 created a function called modefopen, which takes an additional mode
1856 argument. It sets umask(777), creates the file, chmods it to the required
1857 mode, then resets the umask. All the relevant calls to fopen() in the
1858 content scanning code have been changed to use this function.

1895
1896 (i) Exim was not creating retry information for temporary errors given

1898 was used in LMTP mode. This meant that they could be retried too
1899 frequently, and not timed out correctly.
1900
1901 (ii) Exim was setting the flag that allows error details to be returned
1902 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1903 recipients that were returned after the DATA command.
1904
1905PH/53 This is related to PH/52, but is more general: for any failing address,
1906 when detailed error information was permitted to be returned to the

1979PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1980 function verify_get_ident() calls ip_connect() to connect a socket, but
1981 if the "connect()" function timed out, ip_connect() used to close the
1982 socket. However, verify_get_ident() also closes the socket later, and in
1983 between Exim writes to the log, which may get opened at this point. When
1984 the socket was closed in ip_connect(), the log could get the same file
1985 descriptor number as the socket. This naturally causes chaos. The fix is
1986 not to close the socket in ip_connect(); the socket should be closed by
1987 the function that creates it. There was only one place in the code where
1988 this was missing, in the iplookup router, which I don't think anybody now
1989 uses, but I've fixed it anyway.

2012
2013 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2014 string.
2015
2016 (3) Reset the variables that are obtained from the first argument of
2017 ${prvscheck and used in the second argument before leaving the code,
2018 because their memory is reclaimed, so using them afterwards may do
2019 silly things.
2020
2021 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2022 one (it's much easier than Tom thought :-).

2046 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2047 not being looked up in the rDNS to get a host name, Exim was showing the
2048 IP address twice in Received: lines, even though the IP addresses were
2049 identical. For example:
2050
2051 Received: from [1.2.3.4] (helo=[1.2.3.4])
2052
2053 However, if the real host name was known, it was omitting the HELO data
2054 if it matched the actual IP address. This has been tidied up so that it
2055 doesn't show the same IP address twice.

2087 warnings). In the case of bounce messages for non-SMTP mesages, there was
2088 also a typo: it was using "Auto_submitted" (underscore instead of
2089 hyphen). Since every message generated by Exim is necessarily in response
2090 to another message, thes have all been changed to:
2091
2092 Auto-Submitted: auto-replied
2093
2094 in accordance with these statements in the RFC:
2095
2096 The auto-replied keyword:

2144PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated

2146 the IP address, check_host() was doing a simple string comparison with
2147 addresses acquired from the DNS when checking that the found name did
2148 have the original IP as one of its addresses. Since any found IPv6
2149 addresses are likely to be in abbreviated form, the comparison could
2150 fail. Luckily, there already exists a function for doing the comparison
2151 by converting both addresses to binary, so now that is used instead of
2152 the text comparison.

PH
2449PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2450 with the definition in sysexits.h (which is #included earlier).
2451 Fortunately, Exim does not actually use EX_OK. The code used to try to
2452 preserve the sysexits.h value, by assumimg that macro definitions were
2453 scanned for macro replacements. I have been disabused of this notion,
2454 so now the code just undefines EX_OK before #including unistd.h.

PH
2456PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
2457 in the smtp transport. When a block could not be written in a single
2458 write() function, the timeout was being re-applied to each part-write.
2459 This seems wrong - if the receiver was accepting one byte at a time it
2460 would take for ever. The timeout is now adjusted when this happens. It
2461 doesn't have to be particularly precise.

2535 the configuration file to be ":syslog", then the script "guesses" where
2536 the logs files are, rather than using the compiled in default. In our
2537 case the guess is not the same as the compiled default, so the script
2538 suddenly stopped working when I started to use syslog. The patch checks
2539 to see if log_file_path is "". If so, it attempts to read it from exim
2540 with no configuration file to get the compiled in version, before it
2541 falls back to the previous guessing code."

2591 picked up on a user's system that detects such things. There doesn't seem
2592 to be a gcc warning option for this - only an attribute that has to be
2593 put on the function's prototype. It seems that in Fedora Core 4 they have
2594 set this on a number of new functions. No doubt there will be more in due
2595 course.

PH
2597PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
2598 specify a transport. However, if an address that was verified by such a
2599 router was the subject of a callout, Exim crashed because it tried to
2600 read the rcpt_include_affixes from the non-existent transport. Now it
2601 just assumes that the setting of that option is false. This bug was
2602 introduced by 4.51/PH/31.

2612PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
2613 aren't the modern standard, and it seems that some systems' include files
2614 don't always have them. Exim was already checking for some of the newer
2615 ones like T_AAAA, and defining it itself. I've added checks for all the
2616 record types that Exim uses.

PH
2618PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
2619 not automatically generating a new one, as it is supposed to. This
2620 prevented TLS from working. If the file did exist, but contained invalid
2621 data, a new version was generated, as expected. It was only the case of a
2622 non-existent file that was broken.

2633PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
2634 the use of a port name that isn't defined in /etc/services) occurred, the

2638 same time.

2669
2670PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2671 that changes the way the GnuTLS parameters are stored in the cache file.
2672 The new format can be generated externally. For backward compatibility,
2673 if the data in the cache doesn't make sense, Exim assumes it has read an
2674 old-format file, and it generates new data and writes a new file. This
2675 means that you can't go back to an older release without removing the
2676 file.
2677
2678PH/03 A redirect router that has both "unseen" and "one_time" set does not
2679 work if there are any delivery delays because "one_time" forces the
2680 parent to be marked "delivered", so its unseen clone is never tried
2681 again. For this reason, Exim now forbids the simultaneous setting of
2682 these two options.
2683
2684PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2685 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2686 entry if you want to know the details. The fix, however, neglected to
2687 consider the case when local delivery batching is involved. The test for
2688 "previously delivered" was not happening when checking to see if an
2689 address could be batched with a previous (undelivered) one; under
2690 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2691 address.
1a46a8c5
PH
2692
2693PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
2694 in its include files, and this causes problems building Exim.
2695
2696PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2697 header_syntax) but Exim was just ignoring anything given after a slash.
2698 In particular, this caused confusion with an attempt to use "verify =
2699 reverse_host_lookup/defer_ok". An error is now given when options are
2700 supplied for verify items that do not have them. (Maybe reverse_host_
2701 lookup should have a defer_ok option, but that's a different point.)
2702
2703PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
2704 defined by RFC 821) to 2048, because there were problems with some AUTH

2706 SMTP commands that take arguments.

2753PH/19 When an Exim process that is running as root has to create an Exim log
2754 file, it does so in a subprocess that runs as exim:exim so as to get the
2755 ownership right at creation (otherwise, other Exim processes might see
2756 the file with the wrong ownership). There was no test for failure of this
2757 fork() call, which would lead to the process getting stuck as it waited
2758 for a non-existent subprocess. Forks do occasionally fail when resources
2759 run out. I reviewed all the other calls to fork(); they all seem to check
2760 for failure.

2766 string after "input=" when read() returned zero. If read() returned -1

2776PH/23 The cyrus_sasl authenticator was expanding server_hostname, but then
2777 forgetting to use the resulting value; it was using the unexpanded value.

PH
2779PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2780 hadn't been configured. The fix is from Juergen Kreileder, who
2781 understands it better than I do:
2782
2783 "Here's what I see happening with three configured cyrus_sasl
2784 authenticators configured (plain, login, cram-md5):
2785
2786 On startup auth_cyrus_sasl_init() gets called for each of these.
2787 This means three calls to sasl_listmech() without a specified mech_list.
2788 => SASL tests which mechs of all available mechs actually work
2789 => three warnings about OTP not working
2790 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2791
2792 With the patch, sasl_listmech() also gets called three times. But now
2793 SASL's mech_list option is set to the server_mech specified in the the
2794 authenticator. Or in other words, the answer from sasl_listmech()
2795 gets limited to just the mech you're testing for (which is different
2796 for each call.)
2797 => the return list contains just 'plain' or 'login', 'cram-md5' or
2798 nothing depending on the value of ob->server_mech.
2799
2800 I've just tested the patch: Authentication still works fine,
2801 unavailable mechs specified in the exim configuration are still
2802 caught, and the auth.log warnings about OTP are gone."

PH
2866PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2867 the grounds that routing the same address twice would always produce the
2868 same answer. This might have been true once, but it is certainly no
2869 longer true now. Routing a child address may depend on the previous
2870 routing that produced that child. Some complicated redirection strategies
2871 went wrong when messages had multiple recipients, and made Exim's
2872 behaviour dependent on the order in which the addresses were given.
2873
2874 I have moved the duplicate checking until after the routing is complete.
2875 Exim scans the addresses that are assigned to local and remote
2876 transports, and removes any duplicates. This means that more work will be
2877 done, as duplicates will always all be routed, but duplicates are
2878 presumably rare, so I don't expect this is of any significance.
2879
2880 For deliveries to pipes, files, and autoreplies, the duplicate checking
2881 still happens during the routing process, since they are not going to be
2882 routed further.

2888 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it

2915 as "unrouteable address" or "local delivery error" are given.

2926 successful delivery. Such timeouts include transport filter timeouts. For
2927 consistency with the overall process timeout, these timeouts are now
2928 treated as errors, giving rise to delivery failures by default. However,
2929 there is now a new Boolean option for the pipe transport called
2930 timeout_defer, which, if set TRUE, converts the failures into defers for
2931 both kinds of timeout. A transport filter timeout is now identified in

2941A note about Exim versions 4.44 and 4.50
2942----------------------------------------
2943
2944Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2945changes of various kinds. As a consequence, a big documentation update was
2946needed. This delayed the release for rather longer than seemed good, especially
2947in the light of a couple of (minor) security issues. Therefore, the changes
2948that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2949release. So 4.44 and 4.50 are in effect two different branches that both start
2950from 4.43.
2951
2952I have left the 4.50 change log unchanged; it contains all the changes since
29534.43. The change log for 4.44 is below; many of its items are identical to
2954those for 4.50. This seems to be the most sensible way to preserve the
2955historical information.

2973 5. There are several places where Exim runs a non-Exim command in a
2974 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2975 was being done only for the command run by the queryprogram router. It is
2976 now done for all such subprocesses. The other cases are: ${run, transport
2977 filters, and the commands run by the lmtp and pipe transports.

2981 7. Some older OS have a limit of 256 on the maximum number of file
2982 descriptors. Exim was using setrlimit() to set 1000 as a large value
2983 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2984 systems. I've change it so that if it can't get 1000, it tries for 256.

2989 "control" were broken. There should now be diagnostics for all cases when a
2990 control that does not make sense is encountered.

303122. $host_address is now set to the target address during the checking of
3032 ignore_target_hosts.
3033
303423. When checking ignore_target_hosts for an ipliteral router, no host name was
3035 being passed; this would have caused $sender_host_name to have been used if
3036 matching the list had actually called for a host name (not very likely,
3037 since this list is usually IP addresses). A host name is now passed as
3038 "[x.x.x.x]".
3039
7d468ab8
PH
304024. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3041 code that specifies a non-restarting handler (typically sigaction() in
3042 modern systems) in an attempt to fix a rare and obscure crash bug.
3043
304425. Narrowed the window for a race in the daemon that could cause it to ignore
3045 SIGCHLD signals. This is not a major problem, because they are used only to
3046 wake it up if nothing else does.
3047
62c0818f
PH
304826. A malformed maildirsize file could cause Exim to calculate negative values

3050 The maildirsize information is now recalculated if the size or filecount
3051 end up negative.

PH
305829. In an address list, if the pattern was not a regular expression, an empty
3059 subject address (from a bounce message) matched only if the pattern was an
3060 empty string. Non-empty patterns were not even tested. This was the wrong
3061 because it is perfectly reasonable to use an empty address as part of a
3062 database query. An empty address is now tested by patterns that are
3063 lookups. However, all the other forms of pattern expect the subject to
3064 contain a local part and a domain, and therefore, for them, an empty
3065 address still always fails if the pattern is not itself empty.
3066
d8ef3577
PH
306730. Exim went into a mad DNS loop when attempting to do a callout where the
3068 host was specified on an smtp transport, and looking it up yielded more
3069 than one IP address.
3070
5cb8cbc6
PH
307131. Re-factored the code for checking spool and log partition space into a
3072 function that finds that data and another that does the check. The former
3073 is then used to implement four new variables: $spool_space, $log_space,
3074 $spool_inodes, and $log_inodes.
3075
14702f5b
PH
307632. The RFC2047 encoding function was originally intended for short strings
3077 such as real names; it was not keeping to the 75-character limit for
3078 encoded words that the RFC imposes. It now respects the limit, and
3079 generates multiple encoded words if necessary. To be on the safe side, I
3080 have increased the buffer size for the ${rfc2047: expansion operator from
3081 1024 to 2048 bytes.
3082
063b1e99
PH
308333. It is now permitted to omit both strings after an "if" condition; if the
3084 condition is true, the result is "true". As before, when the second string
3085 is omitted, a false condition yields an empty string. This makes it less
3086 cumbersome to write custom ACL and router conditions.
3087
652e1b65
PH
308834. Failure to deliver a bounce message always caused it to be frozen, even if
3089 there was an errors_to setting on the router. The errors_to setting is now
3090 respected.
3091
6f0c9a4f
PH
309235. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3093 canonical form (fully expanded) before being placed in
3094 $sender_host_address.
3095
33397d19
PH
309636. The table in the code that translates DNS record types into text (T_A to
3097 "A" for instance) was missing entries for NS and CNAME. It is just possible
3098 that this could have caused confusion if both these types were looked up
3099 for the same domain, because the text type is used as part of Exim's
3100 per-process caching. But the chance of anyone hitting this buglet seems
3101 very small.
3102
7bb56e1f
PH
310337. The dnsdb lookup has been extended in a number of ways.
3104
3105 (1) There is a new type, "zns", which walks up the domain tree until it
3106 finds some nameserver records. It should be used with care.

PH
3108 (2) There is a new type, "mxh", which is like "mx" except that it returns

3139 < 0 before doing a fflush(). This bug looks as though it goes back to the

3166 recorded - for instance if somebody sent an entire SpamAssassin report back
3167 as a large number of 550 error lines. This bug was coincidentally fixed by
3168 increasing the size of one of Exim's internal buffers (big_buffer) that
3169 happened as part of the Exiscan merge. However, to be on the safe side, I
3170 have made the code more robust (and fixed the comments that describe what
3171 is going on).

PH
317353. Now that there can be additional text after "Completed" in log lines (if
3174 the queue_time_overall log selector is set), a one-byte patch to exigrep
3175 was needed to allow it to recognize "Completed" as not the last thing in
3176 the line.

PH
317854. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3179 patch that reportedly fixes this has been added. I am not expert enough to
3180 create a test for it. This is what the patch creator wrote:
3181
3182 "I found a little strange behaviour of ldap code when working with
3183 Windows 2003 AD Domain, where users was placed in more than one
3184 Organization Units. When I tried to give exim partial DN, the exit code
3185 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3186 But simultaneously result of request was absolutely normal ldap result,
3187 so I produce this patch..."
3188
3295e65b
PH
3189 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3190 REFERENCE, so I have modified the code to exclude the patch when that macro
3191 is not defined.
3192

PH
319355. Some experimental protocols are using DNS PTR records for new purposes. The
3194 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3195 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3196 leaves it alone. Component reversal etc. now happens only for IP addresses.

3202 long debug lines gets shown.

PH
320458. The exicyclog utility now does better if the number of log files to keep
3205 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
3206

PH
320759. Two changes related to the smtp_active_hostname option:
3208
3209 (1) $smtp_active_hostname is now available as a variable.
3210 (2) The default for smtp_banner uses $smtp_active_hostname instead
3211 of $primary_hostname.
3212
b975ba52
PH
321360. The host_aton() function is supposed to be passed a string that is known
3214 to be a valid IP address. However, in the case of IPv6 addresses, it was
3215 not checking this. This is a hostage to fortune. Exim now panics and dies
3216 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3217 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3218 components; fortuitously, this particular loophole had already been fixed
3219 by change 4.50/55 above.
3220
3221 If there are any other similar loopholes, the new check in host_aton()
3222 itself should stop them being exploited. The report I received stated that
3223 data on the command line could provoke the exploit when Exim was running as
3224 exim, but did not say which command line option was involved. All I could
3225 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3226 running as the user.

322961. There was a buffer overflow vulnerability in the SPA authentication code
3230 (which came originally from the Samba project). I have added a test to the

PH
323763. The daemon start-up calls getloadavg() while still root for those OS that
3238 need the first call to be done as root, but it missed one case: when
3239 deliver_queue_load_max is set with deliver_drop_privilege. This is
3240 necessary for the benefit of the queue runner, because there is no re-exec
3241 when deliver_drop_privilege is set.
3242

PH
324364. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3244 This has been fixed.
3245
60dc5e56
PH
324665. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3247 was in use, was not putting the data itself into the right store pool;
3248 consequently, it could be overwritten for a subsequent message in the same
3249 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3250 the caching.)
3251

PH
325266. Added hosts_max_try_hardlimit to the smtp transport, default 50.

PH
325467. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3255 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3256 the function were treating the return as a boolean value, which happened to
3257 work because 0=false and not-0=true, but is not correct code.
3258
7e634d24
PH
325968. The host_aton() function was not handling scoped IPv6 addresses (those
3260 with, for example, "%eth0" on the end) correctly.
3261

PH
326269. Fixed some compiler warnings in acl.c for the bitmaps specified with
3263 negated items (that is, ~something) in unsigned ints. Some compilers
3264 apparently mutter when there is no cast.
3265
6729cf78
PH
326670. If an address verification called from an ACL failed, and did not produce a
3267 user-specific message (i.e. there was only a "system" message), nothing was
3268 put in $acl_verify_message. In this situation, it now puts the system
3269 message there.
3270
00f00ca5
PH
327171. Change 4.23/11 added synchronization checking at the start of an SMTP
3272 session; change 4.31/43 added the unwanted input to the log line - except
3273 that it did not do this in the start of session case. It now does.
3274
c9bdd01c
PH
327572. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3276 This is wrong and can cause the other end to generate a synchronization
3277 error if it is another Exim or anything else that does the synchronization
3278 check. A QUIT command is no longer sent after a timeout.
3279

328073. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3281 during host lookups.

PH
328374. The defer_ok option of callout verification was not working if it was used
3284 when verifying addresses in header lines, that is, for this case:
3285
3286 verify = header_sender/callout=defer_ok
3287
76a2d7ba
PH
328875. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3289 those file descriptors could be used for SMTP connections. If anything
3290 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3291 could be sent to the SMTP client, causing chaos. The daemon now opens
3292 stdin, stdout, and stderr to /dev/null when it puts itself into the
3293 background.
3294
329576. Arrange for output from Perl's "warn" command to be written to Exim's main
3296 log by default. The user can override this with suitable Perl magic.
3297
04f7d5b9
PH
329877. The use of log_message on a "discard" ACL verb, which is supposed to add to
3299 the log message when discard triggers, was not working for the DATA ACL or
3300 for the non-SMTP ACL.
3301

PH
330278. Error message wording change in sieve.c.
3303
bb6e88ff
PH
330479. If smtp_accept_max_per_host was set, the number of connections could be
3305 restricted to fewer than expected, because the daemon was trying to set up
3306 a new connection before checking whether the processes handling previous
3307 connections had finished. The check for completed processes is now done
3308 earlier. On busy systems, this bug wouldn't be noticed because something
3309 else would have woken the daemon, and it would have reaped the completed
3310 process earlier.
3311
1e70f85b
PH
331280. If a message was submitted locally by a user whose login name contained one
3313 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3314 It caused a spool format error. I have fixed the spool reading code. A
3315 related problem was that the "from" clause in the Received: line became
3316 illegal because of the space(s). It is now covered by ${quote_local_part.
3317
331881. Included the latest eximstats from Steve (adds average sizes to HTML Top
3319 tables).

3332----------------------------------------------------
3333See the note above about the 4.44 and 4.50 releases.
3334----------------------------------------------------
3335
3336
3337Exim version 4.44
3338-----------------
3339
3340 1. Change 4.43/35 introduced a bug that caused file counts to be
3341 incorrectly computed when quota_filecount was set in an appendfile
3342 transport
3343
3344 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3345 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3346 place.
3347
3348 3. Give more explanation in the error message when the command for a transport
3349 filter fails to execute.
3350
3351 4. There are several places where Exim runs a non-Exim command in a
3352 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3353 was being done only for the command run by the queryprogram router. It is
3354 now done for all such subprocesses. The other cases are: ${run, transport
3355 filters, and the commands run by the lmtp and pipe transports.
3356
3357 5. Some older OS have a limit of 256 on the maximum number of file
3358 descriptors. Exim was using setrlimit() to set 1000 as a large value
3359 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3360 systems. I've change it so that if it can't get 1000, it tries for 256.
3361
3362 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3363 was an oversight, and furthermore, ever since the addition of extra
3364 controls (e.g. 4.43/32), the checks on when to allow different forms of
3365 "control" were broken. There should now be diagnostics for all cases when a
3366 control that does not make sense is encountered.
3367
3368 7. $recipients is now available in the predata ACL (oversight).
3369
3370 8. Tidy the search cache before the fork to do a delivery from a message
3371 received from the command line. Otherwise the child will trigger a lookup
3372 failure and thereby defer the delivery if it tries to use (for example) a
3373 cached ldap connection that the parent has called unbind on.
3374
3375 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3376 of $address_data from the recipient verification was clobbered by the
3377 sender verification.
3378
337910. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3380 was its contents. (It was OK if the option was not defined at all.)
3381
338211. A "Completed" log line is now written for messages that are removed from
3383 the spool by the -Mrm option.
3384
338512. $host_address is now set to the target address during the checking of
3386 ignore_target_hosts.
3387
338813. When checking ignore_target_hosts for an ipliteral router, no host name was
3389 being passed; this would have caused $sender_host_name to have been used if
3390 matching the list had actually called for a host name (not very likely,
3391 since this list is usually IP addresses). A host name is now passed as
3392 "[x.x.x.x]".
3393
339414. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3395 code that specifies a non-restarting handler (typically sigaction() in
3396 modern systems) in an attempt to fix a rare and obscure crash bug.
3397
339815. Narrowed the window for a race in the daemon that could cause it to ignore
3399 SIGCHLD signals. This is not a major problem, because they are used only to
3400 wake it up if nothing else does.
3401
340216. A malformed maildirsize file could cause Exim to calculate negative values
3403 for the mailbox size or file count. Odd effects could occur as a result.
3404 The maildirsize information is now recalculated if the size or filecount
3405 end up negative.
3406
340717. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3408 support for a long time. Removed HAVE_SYS_VFS_H.
3409
ea3a6f44 341018. Updated exipick to current release from John Jetmore.
