74 when unlink() failed. See also change 4.74-TF/03.
75
921b12ca
TF
76TF/03 Make the exiwhat support code safe for signals. Previously Exim might
77 lock up or crash if it happened to be inside a call to libc when it
78 got a SIGUSR1 from exiwhat.
79
80 The SIGUSR1 handler appends the current process status to the process
81 log which is later printed by exiwhat. It used to use the general
82 purpose logging code to do this, but several functions it calls are
83 not safe for signals.
84
85 The new output code in the SIGUSR1 handler is specific to the process
86 log, and simple enough that it's easy to inspect for signal safety.
87 Removing some special cases also simplifies the general logging code.
88 Removing the spurious timestamps from the process log simplifies
89 exiwhat.
90
c99ce5c9
TF
91TF/04 Improved ratelimit ACL condition.
92
93 The /noupdate option has been deprecated in favour of /readonly which
94 has clearer semantics. The /leaky, /strict, and /readonly update modes
95 are mutually exclusive. The update mode is no longer included in the
96 database key; it just determines when the database is updated. (This
97 means that when you upgrde Exim will forget old rate measurements.)
98
99 Exim now checks that the per_* options are used with an update mode that
100 makes sense for the current ACL. For example, when Exim is processing a
101 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
102 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
103 must specify per_mail/readonly. If you omit the update mode it defaults to
104 /leaky where that makes sense (as before) or /readonly where required.
105
106 The /noupdate option is now undocumented but still supported for
107 backwards compatibility. It is equivalent to /readonly except that in
108 ACLs where /readonly is required you may specify /leaky/noupdate or
109 /strict/noupdate which are treated the same as /readonly.
110
111 A useful new feature is the /count= option. This is a generalization
112 of the per_byte option, so that you can measure the throughput of other
113 aggregate values. For example, the per_byte option is now equivalent
114 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
115
116 The per_rcpt option has been generalized using the /count= mechanism
117 (though it's more complicated than the per_byte equivalence). When it is
118 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
119 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
120 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
121 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
122 Note that using per_rcpt with a non-readonly update mode in more than
123 one ACL will cause the recipients to be double-counted. (The per_mail
124 and per_byte options don't have this problem.)
125
126 The handling of very low rates has changed slightly. If the computed rate
127 is less than the event's count (usually one) then this event is the first
128 after a long gap. In this case the rate is set to the same as this event's
129 count, so that the first message of a spam run is counted properly.
130
131 The major new feature is a mechanism for counting the rate of unique
132 events. The new per_addr option counts the number of different
133 recipients that someone has sent messages to in the last time period. It
134 behaves like per_rcpt if all the recipient addresses are different, but
135 duplicate recipient addresses do not increase the measured rate. Like
136 the /count= option this is a general mechanism, so the per_addr option
137 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
138 example, measure the rate that a client uses different sender addresses
139 with the options per_mail/unique=$sender_address. There are further
140 details in the main documentation.

712PH/01 Another patch from the Sieve maintainer.
713
6a3bceb1
PH
714PH/02 When an IPv6 address is converted to a string for single-key lookup
715 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
716 dots are used instead of colons so that keys in lsearch files need not
717 contain colons. This was done some time before quoting was made available
718 in lsearch files. However, iplsearch files do require colons in IPv6 keys
719 (notated using the quote facility) so as to distinguish them from IPv4
720 keys. This meant that lookups for IP addresses in host lists did not work
721 for iplsearch lookups.
722
723 This has been fixed by arranging for IPv6 addresses to be expressed with
724 colons if the lookup type is iplsearch. This is not incompatible, because
725 previously such lookups could never work.
726
727 The situation is now rather anomolous, since one *can* have colons in
728 ordinary lsearch keys. However, making the change in all cases is
729 incompatible and would probably break a number of configurations.

734MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
735 conversion specification without a maximum field width, thereby enabling
736 a rogue spamd server to cause a buffer overflow. While nobody in their
737 right mind would setup Exim to query an untrusted spamd server, an
738 attacker that gains access to a server running spamd could potentially
739 exploit this vulnerability to run arbitrary code as the Exim user.

MH
744MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
745 a directory entry by the name of the lookup key. Previously, if a
746 symlink pointed to a non-existing file or a file in a directory that
747 Exim lacked permissions to read, a lookup for a key matching that
748 symlink would fail. Now it is enough that a matching directory entry
749 exists, symlink or not. (Bugzilla 503.)

932PH/29 SMTP synchronization checks are implemented when a command is read -
933 there is a check that no more input is waiting when there shouldn't be
934 any. However, for some commands, a delay in an ACL can mean that it is
935 some time before the response is written. In this time, more input might
936 arrive, invalidly. So now there are extra checks after an ACL has run for
937 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
938 pipelining has not been advertised.

1012 the response to the final '.' that terminates a message, but only in the
1013 case where the client has not sent further data following the '.'
1014 (unfortunately, this is allowed). However, in many cases there won't be
1015 any further data because there won't be any more messages to send. A call
1016 to select() can be used: if it shows that the input is "ready", there is
1017 either input waiting, or the socket has been closed. An attempt to read
1018 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1019 would have sent an OK response which the client would never have see.

1030PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1031 fixed by 4.65/MH/01 (is this a record?) are fixed:
1032
1033 (i) An empty string was always treated as zero by the numeric comparison
1034 operators. This behaviour has been restored.
1035
1036 (ii) It is documented that the numeric comparison operators always treat
1037 their arguments as decimal numbers. This was broken in that numbers
1038 starting with 0 were being interpreted as octal.
1039
1040 While fixing these problems I realized that there was another issue that
1041 hadn't been noticed. Values of message_size_limit (both the global option
1042 and the transport option) were treated as octal if they started with 0.
1043 The documentation was vague. These values are now always treated as
1044 decimal, and I will make that clear in the documentation.

1061 large number of recipients for a single message is ridiculous
1062 (performance will be very, very poor), I have chosen to impose a limit
1063 rather than extend the field.

2b1c6e3a
PH
1088PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1089 callout verification, Exim cached a "reject" for the entire domain. This
1090 is correct for most verifications, but it is not correct for a recipient
1091 verification with use_sender or use_postmaster set, because in that case
1092 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1093 case of MAIL FROM:<> rejection from other early rejections (e.g.
1094 rejection of HELO). When verifying a recipient using a non-null MAIL
1095 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1096 Whatever the result of the callout, the value of the domain cache is
1097 left unchanged (for any other kind of callout, getting as far as trying
1098 RCPT means that the domain itself is ok).

1132PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1134 probably the interface on which it is arriving) and not to the outgoing
1135 callout (which could be using a different interface). This has been
1136 changed to use the value of the helo_data option from the smtp transport
1137 instead - this is what is used when a message is actually being sent. If
1138 there is no remote transport (possible with a router that sets up host
1139 addresses), $smtp_active_hostname is used.

7befa435 1142 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1143 (a) The code assumed that strncpy() returns a negative number on buffer
1144 overflow, which isn't the case. Replaced with Exim's string_format()
1145 function.
1146 (b) There were several signed/unsigned issues. I just did the minimum
1147 hacking in of casts. There is scope for a larger refactoring.
1148 (c) The code used strcasecmp() which is not a standard C function.
1149 Replaced with Exim's strcmpic() function.
1150 (d) The code set only $1; it now sets $auth1 as well.
1151 (e) A simple test gave the error "authentication client didn't specify
1152 service in request". It would seem that Dovecot has changed its
1153 interface. Fortunately there's a specification; I followed it and
1154 changed what the client sends and it appears to be working now.

1160 address A is aliased to B and C, where B exists and C does not. Without
1161 -v the output is "A verified" because verification stops after a
1162 successful redirection if more than one address is generated. However,
1163 with -v the child addresses are also verified. Exim was outputting "A
1164 failed to verify" and then showing the successful verification for C,
1165 with its parentage. It now outputs "B failed to verify", showing B's
1166 parentage before showing the successful verification of C.

322050c2
PH
1172PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1173 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1174 they consult the DNS. I had assumed they would set it the way they
1175 wanted; and indeed my experiments on Linux seem to show that in some
1176 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1177 To be on the safe side, however, I have now made the interface to
1178 host_find_byname() similar to host_find_bydns(), with an argument
1179 containing the DNS resolver options. The host_find_byname() function now
1180 sets these options at its start, just as host_find_bydns() does. The smtp
1181 transport options dns_qualify_single and dns_search_parents are passed to
1182 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1183 of host_find_byname() use the default settings of RES_DEFNAMES
1184 (qualify_single) but not RES_DNSRCH (search_parents).

1187 spool_read_header() do less string testing, by means of a preliminary
1188 switch on the second character of optional "-foo" lines. (This is
1189 overdue, caused by the large number of possibilities that now exist.
1190 Originally there were few.) While I was there, I also converted the
1191 str(n)cmp tests so they don't re-test the leading "-" and the first
1192 character, in the hope this might squeeze out yet more improvement.

1194PH/18 Two problems with "group" syntax in header lines when verifying: (1) The

1197 set at all for the header_verify test, causing "group"-style headers to
1198 be rejected. I have now set it in this case, and also caused header_
1199 verify to ignore an empty address taken from a group. While doing this, I
1200 came across some other cases where the code for allowing group syntax
1201 while scanning a header line wasn't quite right (mostly, not resetting
1202 the flag correctly in the right place). These bugs could have caused
1203 trouble for malformed header lines. I hope it is now all correct.

1205PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1207 came from elsewhere) had *some* tests for NULL when it wrote to *reply,

PH
1211PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1212 feature that was used to support insecure browsers during the U.S. crypto
1213 embargo. It requires special client support, and Exim is probably the
1214 only MTA that supported it -- and would never use it because real RSA is
1215 always available. This code has been removed, because it had the bad
1216 effect of slowing Exim down by computing (never used) parameters for the
1217 RSA_EXPORT functionality.

1222 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1223 if the connection is using TLS or if the remote IP is the same as the
1224 local IP, and the "valid-client-cert option" if a client certificate has
1225 been verified.

1256
1257PH/30 Exim was sometimes attempting to deliver messages that had suffered
1258 address errors (4xx response to RCPT) over the same connection as other
1259 messages routed to the same hosts. Such deliveries are always "forced",
1260 so retry times are not inspected. This resulted in far too many retries
1261 for the affected addresses. The effect occurred only when there were more
1262 hosts than the hosts_max_try setting in the smtp transport when it had
1263 the 4xx errors. Those hosts that it had tried were not added to the list
1264 of hosts for which the message was waiting, so if all were tried, there
1265 was no problem. Two fixes have been applied:
1266
1267 (i) If there are any address or message errors in an SMTP delivery, none
1268 of the hosts (tried or untried) are now added to the list of hosts
1269 for which the message is waiting, so the message should not be a
1270 candidate for sending over the same connection that was used for a
1271 successful delivery of some other message. This seems entirely
1272 reasonable: after all the message is NOT "waiting for some host".
1273 This is so "obvious" that I'm not sure why it wasn't done
1274 previously. Hope I haven't missed anything, but it can't do any
1275 harm, as the worst effect is to miss an optimization.
1276
1277 (ii) If, despite (i), such a delivery is accidentally attempted, the
1278 routing retry time is respected, so at least it doesn't keep
1279 hammering the server.

1294PH/35 The error "getsockname() failed: connection reset by peer" was being
1295 written to the panic log as well as the main log, but it isn't really

1297 removed the panic log writing for the ECONNRESET error when getsockname()
1298 fails.

48c7f9e2
PH
1300PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1301 runs only) independently of the message's sender address. This meant
1302 that, if the 4xx error was in fact related to the sender, a different
1303 message to the same recipient with a different sender could confuse
1304 things. In particualar, this can happen when sending to a greylisting
1305 server, but other circumstances could also provoke similar problems.
1306 I have changed the default so that the retry time for these errors is now
1307 based a combination of the sender and recipient addresses. This change
1308 can be overridden by setting address_retry_include_sender=false in the
1309 smtp transport.

1621PH/01 The code for finding all the local interface addresses on a FreeBSD
1622 system running IPv6 was broken. This may well have applied to all BSD
1623 systems, as well as to others that have similar system calls. The broken
1624 code found IPv4 interfaces correctly, but gave incorrect values for the
1625 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1626 that it would not match correctly against @[] and not recognize the IPv6
1627 addresses as local.

1670 autoreply, Exim could try to deliver to a non-existent relative file

1694 in a subprocess such as that created by queryprogram now generate
1695 suitable debugging ouput when -d is set.

1706 Instead, it always explicitly searches for A/AAAA records. This avoids
1707 major problems that occur when a DNS server includes only records of one
1708 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1709 fixed another bug: if SRV records were looked up and the corresponding
1710 address records were *not* found in the additional section, the port
1711 values from the SRV records were lost.

PH
1721PH/19 When calculating a retry time, Exim used to measure the "time since
1722 failure" by looking at the "first failed" field in the retry record. Now
1723 it does not use this if it is later than than the arrival time of the
1724 message. Instead it uses the arrival time. This makes for better
1725 behaviour in cases where some deliveries succeed, thus re-setting the
1726 "first failed" field. An example is a quota failure for a huge message
1727 when small messages continue to be delivered. Without this change, the
1728 "time since failure" will always be short, possible causing more frequent
1729 delivery attempts for the huge message than are intended.

PH
1826PH/42 The content-scanning code uses fopen() to create files in which to put
1827 message data. Previously it was not paying any attention to the mode of
1828 the files. Exim runs with umask(0) because the rest of the code creates
1829 files with open(), and sets the required mode explicitly. Thus, these
1830 files were ending up world-writeable. This was not a big issue, because,
1831 being within the spool directory, they were not world-accessible. I have
1832 created a function called modefopen, which takes an additional mode
1833 argument. It sets umask(777), creates the file, chmods it to the required
1834 mode, then resets the umask. All the relevant calls to fopen() in the
1835 content scanning code have been changed to use this function.

1872
1873 (i) Exim was not creating retry information for temporary errors given
1874 for individual recipients after the DATA command when the smtp transport
1875 was used in LMTP mode. This meant that they could be retried too
1876 frequently, and not timed out correctly.
1877
1878 (ii) Exim was setting the flag that allows error details to be returned
1879 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1880 recipients that were returned after the DATA command.
1881
1882PH/53 This is related to PH/52, but is more general: for any failing address,
1883 when detailed error information was permitted to be returned to the

1957 function verify_get_ident() calls ip_connect() to connect a socket, but
1958 if the "connect()" function timed out, ip_connect() used to close the
1959 socket. However, verify_get_ident() also closes the socket later, and in
1960 between Exim writes to the log, which may get opened at this point. When
1961 the socket was closed in ip_connect(), the log could get the same file
1962 descriptor number as the socket. This naturally causes chaos. The fix is
1963 not to close the socket in ip_connect(); the socket should be closed by
1964 the function that creates it. There was only one place in the code where
1965 this was missing, in the iplookup router, which I don't think anybody now

1976PH/01 Two changes to the default runtime configuration:
1977
1978 (1) Move the checks for relay_from_hosts and authenticated clients from
1979 after to before the (commented out) DNS black list checks.
1980
1981 (2) Add control=submission to the relay_from_hosts and authenticated
1982 clients checks, on the grounds that messages accepted by these
1983 statements are most likely to be submissions.

PH
1985PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
1986
1987 (1) Generate an error if the third argument for the ${prvs expansion is
1988 not a single digit.
1989
1990 (2) Treat a missing third argument of ${prvscheck as if it were an empty
1991 string.
1992
1993 (3) Reset the variables that are obtained from the first argument of
1994 ${prvscheck and used in the second argument before leaving the code,
1995 because their memory is reclaimed, so using them afterwards may do
1996 silly things.
1997
1998 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
1999 one (it's much easier than Tom thought :-).
2000
2001 (5) Because of (4), we can now allow for the use of $prvscheck_result
2002 inside the third argument.

PH
2011PH/05 When a filter generated an autoreply, the entire To: header line was
2012 quoted in the delivery log line, like this:
2013
2014 => >A.N.Other <ano@some.domain> <original@ddress> ...
2015
2016 This has been changed so that it extracts the operative address. There
2017 may be more than one such address. If so, they are comma-separated, like
2018 this:
2019
2020 => >ano@some.domain,ona@other.domain <original@ddress> ...
2021
82c19f95
PH
2022PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2023 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2024 not being looked up in the rDNS to get a host name, Exim was showing the
2025 IP address twice in Received: lines, even though the IP addresses were
2026 identical. For example:
2027
2028 Received: from [1.2.3.4] (helo=[1.2.3.4])
2029
2030 However, if the real host name was known, it was omitting the HELO data
2031 if it matched the actual IP address. This has been tidied up so that it
2032 doesn't show the same IP address twice.
2033

PH
2034PH/07 When both +timestamp and +memory debugging was on, the value given by
2035 $tod_xxx expansions could be wrong, because the tod_stamp() function was
2036 called by the debug printing, thereby overwriting the timestamp buffer.
2037 Debugging no longer uses the tod_stamp() function when +timestamp is set.

PH
2039PH/08 When the original message was included in an autoreply transport, it
2040 always said "this is a copy of the message, including all the headers",
2041 even if body_only or headers_only was set. It now gives an appropriate
2042 message.

PH
2044PH/09 Applied a patch from the Sieve maintainer which:

2047 o adds the (disabled) notify extension core
2048 o adds some debug output for the result of if/elsif tests
2049 o points to the current vacation draft in the documentation
2050 and documents the missing references header update
2051
2052 and most important:

2055 multiple envelope elements, the last element determinted the
2056 result)

PH
2058PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2059 Electronic Mail") by including:
2060
2061 Auto-submitted: auto-generated
2062
2063 in the messages that it generates (bounce messages and others, such as
2064 warnings). In the case of bounce messages for non-SMTP mesages, there was
2065 also a typo: it was using "Auto_submitted" (underscore instead of
2066 hyphen). Since every message generated by Exim is necessarily in response
2067 to another message, thes have all been changed to:
2068
2069 Auto-Submitted: auto-replied
2070
2071 in accordance with these statements in the RFC:
2072
2073 The auto-replied keyword:
2074
2075 - SHOULD be used on messages sent in direct response to another
2076 message by an automatic process,
2077
2078 - MUST NOT be used on manually-generated messages,
2079
2080 - MAY be used on Delivery Status Notifications (DSNs) and Message
2081 Disposition Notifications (MDNs),
2082
2083 - MUST NOT be used on messages generated by automatic or periodic
2084 processes, except for messages which are automatic responses to
2085 other messages.

PH
2096PH/14 Add check_rfc2047_length to disable enforcement of RFC 2047 length

2100PH/15 If the first argument of "${if match_address" was not empty, but did not

2106PH/17 A further patch from the Sieve maintainer: "Introduce the new Sieve
2107 extension "envelope-auth". The code is finished and in agreement with
2108 other implementations, but there is no documentation so far and in fact,
2109 nobody wrote the draft yet. This extension is currently #undef'ed, thus
2110 not changing the active code.
2111
2112 Print executed "if" and "elsif" statements when debugging is used. This
2113 helps a great deal to understand what a filter does.
2114
2115 Document more things not specified clearly in RFC3028. I had all this
2116 sorted out, when out of a sudden new issues came to my mind. Oops."

d27f1df3
PH
2121PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2122 canonical form (as documented). However, after a host name lookup from
2123 the IP address, check_host() was doing a simple string comparison with
2124 addresses acquired from the DNS when checking that the found name did
2125 have the original IP as one of its addresses. Since any found IPv6
2126 addresses are likely to be in abbreviated form, the comparison could
2127 fail. Luckily, there already exists a function for doing the comparison
2128 by converting both addresses to binary, so now that is used instead of
2129 the text comparison.
2130
96776534
PH
2131PH/20 There was another similar case to PH/19, when a complete host name was
2132 given in a host list; looking up its IP address could give an abbreviated
2133 form, whereas the current host's name might or might not be abbreviated.
2134 The same fix has been applied.

PH
2213PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true

PH
2393PH/01 When a transport filter timed out in a pipe delivery, and the pipe
2394 command itself ended in error, the underlying message about the transport
2395 filter timeout was being overwritten with the pipe command error. Now the
2396 underlying error message should be appended to the second error message.

PH
2403PH/03 The warning log line about a condition test deferring for a "warn" verb
2404 was being output only once per connection, rather than after each
2405 occurrence (because it was using the same function as for successful
2406 "warn" verbs). This seems wrong, so I have changed it.

PH
2408TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that
2409 it should not have, which might have caused a crash in the right
2410 circumstances, but probably never did.
2411
2412PH/04 Installed a modified version of Tony Finch's patch to make submission
2413 mode fix the return path as well as the Sender: header line, and to

PH
2426PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2427 with the definition in sysexits.h (which is #included earlier).
2428 Fortunately, Exim does not actually use EX_OK. The code used to try to
2429 preserve the sysexits.h value, by assumimg that macro definitions were
2430 scanned for macro replacements. I have been disabused of this notion,
2431 so now the code just undefines EX_OK before #including unistd.h.
11d337a4 2432
958541e9
PH
2433PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
2434 in the smtp transport. When a block could not be written in a single
2435 write() function, the timeout was being re-applied to each part-write.
2436 This seems wrong - if the receiver was accepting one byte at a time it
2437 would take for ever. The timeout is now adjusted when this happens. It
2438 doesn't have to be particularly precise.

2472PH/08 The ${def test on a variable was returning false if the variable's

2476PH/09 The syntax error of a character other than { following "${if
2477 def:variable_name" (after optional whitespace) was not being diagnosed.
2478 An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an

PH
2504PH/15 The code I had for printing potentially long long variables in PH/11
2505 above was not the best (it lost precision). The length of off_t variables
2506 is now inspected at build time, and an appropriate printing format (%ld
c6c2dc1d
PH
2507 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
2508 to be "long long int" or "long int". This is needed for the internal
2509 formatting function string_vformat().

PH
2511PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
2512 the configuration file to be ":syslog", then the script "guesses" where
2513 the logs files are, rather than using the compiled in default. In our
2514 case the guess is not the same as the compiled default, so the script
2515 suddenly stopped working when I started to use syslog. The patch checks
2516 to see if log_file_path is "". If so, it attempts to read it from exim
2517 with no configuration file to get the compiled in version, before it
2518 falls back to the previous guessing code."

PH
2527PH/18 If the "use_postmaster" option was set for a recipient callout together

2530 test. It is now used for both.

PH
2532PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
2533 patch removes a few documentation additions to RFC 3028, because the
2534 latest draft now contains them. It adds the new en;ascii-case comparator
2535 and a new error check for 8bit text in MIME parts. Comparator and
2536 require names are now matched exactly. I enabled the subaddress
2537 extension, but it is not well tested yet (read: it works for me)."

c6c2dc1d
PH

PH
2561PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints
2562 databases so that it will be absolutely obvious if a crash occurs in the
2563 DB library. This is a regular occurrence (often caused by mis-matched
2564 db.h files).
2565
ff790e47 2566PH/26 Insert a lot of missing (void) casts for functions such as chown(),
f1e894f3
PH
2567 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
2568 picked up on a user's system that detects such things. There doesn't seem
2569 to be a gcc warning option for this - only an attribute that has to be
2570 put on the function's prototype. It seems that in Fedora Core 4 they have
2571 set this on a number of new functions. No doubt there will be more in due
2572 course.
ff790e47 2573
5417f6d1
PH
2574PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
2575 specify a transport. However, if an address that was verified by such a
2576 router was the subject of a callout, Exim crashed because it tried to
2577 read the rcpt_include_affixes from the non-existent transport. Now it
2578 just assumes that the setting of that option is false. This bug was
2579 introduced by 4.51/PH/31.

PH

PH
2589PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
2590 aren't the modern standard, and it seems that some systems' include files
2591 don't always have them. Exim was already checking for some of the newer
2592 ones like T_AAAA, and defining it itself. I've added checks for all the
2593 record types that Exim uses.
2594
182ad5cf
PH
2595PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
2596 not automatically generating a new one, as it is supposed to. This
2597 prevented TLS from working. If the file did exist, but contained invalid
2598 data, a new version was generated, as expected. It was only the case of a
2599 non-existent file that was broken.

2610PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
2611 the use of a port name that isn't defined in /etc/services) occurred, the
2612 message was deferred as in a normal delivery, and thus remained on the
2613 spool, instead of being failed because of the mua_wrapper setting. This

2615 same time.

SC
2617SC/08 Eximstats: whilst parsing the mainlog(s), store information about

2645 to test Sieve filters that use "vacation".
2646
2647PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2648 that changes the way the GnuTLS parameters are stored in the cache file.
2649 The new format can be generated externally. For backward compatibility,
2650 if the data in the cache doesn't make sense, Exim assumes it has read an
2651 old-format file, and it generates new data and writes a new file. This
2652 means that you can't go back to an older release without removing the
2653 file.
2654
2655PH/03 A redirect router that has both "unseen" and "one_time" set does not
2656 work if there are any delivery delays because "one_time" forces the
2657 parent to be marked "delivered", so its unseen clone is never tried
2658 again. For this reason, Exim now forbids the simultaneous setting of
2659 these two options.
2660
2661PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2662 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2663 entry if you want to know the details. The fix, however, neglected to
2664 consider the case when local delivery batching is involved. The test for
2665 "previously delivered" was not happening when checking to see if an
2666 address could be batched with a previous (undelivered) one; under
2667 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2668 address.
1a46a8c5
PH
2669
2670PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
2671 in its include files, and this causes problems building Exim.
2672
2673PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2674 header_syntax) but Exim was just ignoring anything given after a slash.
2675 In particular, this caused confusion with an attempt to use "verify =
2676 reverse_host_lookup/defer_ok". An error is now given when options are
2677 supplied for verify items that do not have them. (Maybe reverse_host_
2678 lookup should have a defer_ok option, but that's a different point.)
2679
2680PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
2681 defined by RFC 821) to 2048, because there were problems with some AUTH

2683 SMTP commands that take arguments.

2730PH/19 When an Exim process that is running as root has to create an Exim log
2731 file, it does so in a subprocess that runs as exim:exim so as to get the
2732 ownership right at creation (otherwise, other Exim processes might see
2733 the file with the wrong ownership). There was no test for failure of this
2734 fork() call, which would lead to the process getting stuck as it waited
2735 for a non-existent subprocess. Forks do occasionally fail when resources
2736 run out. I reviewed all the other calls to fork(); they all seem to check
2737 for failure.

2739PH/20 When checking for unexpected SMTP input at connect time (before writing

2742 the result was a log entry for a synchronization error with an empty
2743 string after "input=" when read() returned zero. If read() returned -1
2744 (an event I could not check), uninitialized data bytes were printed.

2755
c5ddb310
PH
2756PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2757 hadn't been configured. The fix is from Juergen Kreileder, who
2758 understands it better than I do:
2759
2760 "Here's what I see happening with three configured cyrus_sasl
2761 authenticators configured (plain, login, cram-md5):
2762
2763 On startup auth_cyrus_sasl_init() gets called for each of these.
2764 This means three calls to sasl_listmech() without a specified mech_list.
2765 => SASL tests which mechs of all available mechs actually work
2766 => three warnings about OTP not working
2767 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2768
2769 With the patch, sasl_listmech() also gets called three times. But now
2770 SASL's mech_list option is set to the server_mech specified in the the
2771 authenticator. Or in other words, the answer from sasl_listmech()
2772 gets limited to just the mech you're testing for (which is different
2773 for each call.)
2774 => the return list contains just 'plain' or 'login', 'cram-md5' or
2775 nothing depending on the value of ob->server_mech.
2776

PH
2843PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2844 the grounds that routing the same address twice would always produce the
2845 same answer. This might have been true once, but it is certainly no
2846 longer true now. Routing a child address may depend on the previous
2847 routing that produced that child. Some complicated redirection strategies
2848 went wrong when messages had multiple recipients, and made Exim's
2849 behaviour dependent on the order in which the addresses were given.
2850
2851 I have moved the duplicate checking until after the routing is complete.
2852 Exim scans the addresses that are assigned to local and remote
2853 transports, and removes any duplicates. This means that more work will be
2854 done, as duplicates will always all be routed, but duplicates are
2855 presumably rare, so I don't expect this is of any significance.
2856
2857 For deliveries to pipes, files, and autoreplies, the duplicate checking
2858 still happens during the routing process, since they are not going to be
2859 routed further.

2904 consistency with the overall process timeout, these timeouts are now
2905 treated as errors, giving rise to delivery failures by default. However,
2906 there is now a new Boolean option for the pipe transport called
2907 timeout_defer, which, if set TRUE, converts the failures into defers for
2908 both kinds of timeout. A transport filter timeout is now identified in

2918A note about Exim versions 4.44 and 4.50
2919----------------------------------------
2920
2921Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2922changes of various kinds. As a consequence, a big documentation update was
2923needed. This delayed the release for rather longer than seemed good, especially
2924in the light of a couple of (minor) security issues. Therefore, the changes
2925that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2926release. So 4.44 and 4.50 are in effect two different branches that both start
2927from 4.43.
2928
2929I have left the 4.50 change log unchanged; it contains all the changes since
29304.43. The change log for 4.44 is below; many of its items are identical to
2931those for 4.50. This seems to be the most sensible way to preserve the
2932historical information.

2950 5. There are several places where Exim runs a non-Exim command in a
2951 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2952 was being done only for the command run by the queryprogram router. It is
2953 now done for all such subprocesses. The other cases are: ${run, transport
2954 filters, and the commands run by the lmtp and pipe transports.

2956 6. Added CONFIGURE_GROUP build-time option.

2958 7. Some older OS have a limit of 256 on the maximum number of file
2959 descriptors. Exim was using setrlimit() to set 1000 as a large value
2960 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2961 systems. I've change it so that if it can't get 1000, it tries for 256.

2966 "control" were broken. There should now be diagnostics for all cases when a
2967 control that does not make sense is encountered.

300822. $host_address is now set to the target address during the checking of
3009 ignore_target_hosts.
3010
301123. When checking ignore_target_hosts for an ipliteral router, no host name was
3012 being passed; this would have caused $sender_host_name to have been used if
3013 matching the list had actually called for a host name (not very likely,
3014 since this list is usually IP addresses). A host name is now passed as
3015 "[x.x.x.x]".
3016
7d468ab8
PH
301724. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3018 code that specifies a non-restarting handler (typically sigaction() in
3019 modern systems) in an attempt to fix a rare and obscure crash bug.
3020
302125. Narrowed the window for a race in the daemon that could cause it to ignore
3022 SIGCHLD signals. This is not a major problem, because they are used only to
3023 wake it up if nothing else does.
3024
62c0818f
PH
302526. A malformed maildirsize file could cause Exim to calculate negative values
3026 for the mailbox size or file count. Odd effects could occur as a result.
3027 The maildirsize information is now recalculated if the size or filecount
3028 end up negative.
3029
26034054

PH
303529. In an address list, if the pattern was not a regular expression, an empty
3036 subject address (from a bounce message) matched only if the pattern was an
3037 empty string. Non-empty patterns were not even tested. This was the wrong
3038 because it is perfectly reasonable to use an empty address as part of a
3039 database query. An empty address is now tested by patterns that are
3040 lookups. However, all the other forms of pattern expect the subject to
3041 contain a local part and a domain, and therefore, for them, an empty
3042 address still always fails if the pattern is not itself empty.
3043
d8ef3577
PH
304430. Exim went into a mad DNS loop when attempting to do a callout where the
3045 host was specified on an smtp transport, and looking it up yielded more
3046 than one IP address.
3047
5cb8cbc6
PH
304831. Re-factored the code for checking spool and log partition space into a
3049 function that finds that data and another that does the check. The former
3050 is then used to implement four new variables: $spool_space, $log_space,
3051 $spool_inodes, and $log_inodes.
3052
14702f5b
PH
305332. The RFC2047 encoding function was originally intended for short strings
3054 such as real names; it was not keeping to the 75-character limit for
3055 encoded words that the RFC imposes. It now respects the limit, and
3056 generates multiple encoded words if necessary. To be on the safe side, I
3057 have increased the buffer size for the ${rfc2047: expansion operator from
3058 1024 to 2048 bytes.
3059
063b1e99
PH
306033. It is now permitted to omit both strings after an "if" condition; if the
3061 condition is true, the result is "true". As before, when the second string
3062 is omitted, a false condition yields an empty string. This makes it less
3063 cumbersome to write custom ACL and router conditions.
3064
652e1b65
PH
306534. Failure to deliver a bounce message always caused it to be frozen, even if
3066 there was an errors_to setting on the router. The errors_to setting is now
3067 respected.
3068
6f0c9a4f
PH
306935. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3070 canonical form (fully expanded) before being placed in
3071 $sender_host_address.
3072
33397d19
PH
307336. The table in the code that translates DNS record types into text (T_A to
3074 "A" for instance) was missing entries for NS and CNAME. It is just possible
3075 that this could have caused confusion if both these types were looked up
3076 for the same domain, because the text type is used as part of Exim's
3077 per-process caching. But the chance of anyone hitting this buglet seems
3078 very small.
3079
7bb56e1f
PH
308037. The dnsdb lookup has been extended in a number of ways.
3081
3082 (1) There is a new type, "zns", which walks up the domain tree until it
3083 finds some nameserver records. It should be used with care.

ea3bc19b
PH
3085 (2) There is a new type, "mxh", which is like "mx" except that it returns

3116 < 0 before doing a fflush(). This bug looks as though it goes back to the

314252. Exim crashed if a remote delivery caused a very long error message to be
3143 recorded - for instance if somebody sent an entire SpamAssassin report back
3144 as a large number of 550 error lines. This bug was coincidentally fixed by
3145 increasing the size of one of Exim's internal buffers (big_buffer) that
3146 happened as part of the Exiscan merge. However, to be on the safe side, I
3147 have made the code more robust (and fixed the comments that describe what
3148 is going on).

PH
315554. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3156 patch that reportedly fixes this has been added. I am not expert enough to
3157 create a test for it. This is what the patch creator wrote:
3158
3159 "I found a little strange behaviour of ldap code when working with
3160 Windows 2003 AD Domain, where users was placed in more than one
3161 Organization Units. When I tried to give exim partial DN, the exit code
3162 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3163 But simultaneously result of request was absolutely normal ldap result,
3164 so I produce this patch..."
3165
3295e65b
PH
3166 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3167 REFERENCE, so I have modified the code to exclude the patch when that macro
3168 is not defined.

3171 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3172 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3173 leaves it alone. Component reversal etc. now happens only for IP addresses.

3179 long debug lines gets shown.

PH
318158. The exicyclog utility now does better if the number of log files to keep

318459. Two changes related to the smtp_active_hostname option:
3185
3186 (1) $smtp_active_hostname is now available as a variable.
3187 (2) The default for smtp_banner uses $smtp_active_hostname instead
3188 of $primary_hostname.

319060. The host_aton() function is supposed to be passed a string that is known
3191 to be a valid IP address. However, in the case of IPv6 addresses, it was
3192 not checking this. This is a hostage to fortune. Exim now panics and dies
3193 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3194 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3195 components; fortuitously, this particular loophole had already been fixed
3196 by change 4.50/55 above.
3197
3198 If there are any other similar loopholes, the new check in host_aton()
3199 itself should stop them being exploited. The report I received stated that
3200 data on the command line could provoke the exploit when Exim was running as
3201 exim, but did not say which command line option was involved. All I could
3202 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3203 running as the user.

320661. There was a buffer overflow vulnerability in the SPA authentication code
3207 (which came originally from the Samba project). I have added a test to the
3208 spa_base64_to_bits() function which I hope fixes it.

PH
321463. The daemon start-up calls getloadavg() while still root for those OS that
3215 need the first call to be done as root, but it missed one case: when
3216 deliver_queue_load_max is set with deliver_drop_privilege. This is
3217 necessary for the benefit of the queue runner, because there is no re-exec
3218 when deliver_drop_privilege is set.

PH
322064. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3221 This has been fixed.
3222
60dc5e56
PH
322365. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3224 was in use, was not putting the data itself into the right store pool;
3225 consequently, it could be overwritten for a subsequent message in the same
3226 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3227 the caching.)

PH
323167. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3232 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3233 the function were treating the return as a boolean value, which happened to
3234 work because 0=false and not-0=true, but is not correct code.
3235
7e634d24
PH
323668. The host_aton() function was not handling scoped IPv6 addresses (those
3237 with, for example, "%eth0" on the end) correctly.

PH
323969. Fixed some compiler warnings in acl.c for the bitmaps specified with
3240 negated items (that is, ~something) in unsigned ints. Some compilers
3241 apparently mutter when there is no cast.
3242

PH
324370. If an address verification called from an ACL failed, and did not produce a
3244 user-specific message (i.e. there was only a "system" message), nothing was
3245 put in $acl_verify_message. In this situation, it now puts the system
3246 message there.
3247

PH
324871. Change 4.23/11 added synchronization checking at the start of an SMTP
3249 session; change 4.31/43 added the unwanted input to the log line - except
3250 that it did not do this in the start of session case. It now does.
3251

PH
325272. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3253 This is wrong and can cause the other end to generate a synchronization
3254 error if it is another Exim or anything else that does the synchronization
3255 check. A QUIT command is no longer sent after a timeout.

326074. The defer_ok option of callout verification was not working if it was used
3261 when verifying addresses in header lines, that is, for this case:
3262
3263 verify = header_sender/callout=defer_ok
3264
76a2d7ba
PH
326575. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3266 those file descriptors could be used for SMTP connections. If anything
3267 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3268 could be sent to the SMTP client, causing chaos. The daemon now opens
3269 stdin, stdout, and stderr to /dev/null when it puts itself into the
3270 background.
3271
327276. Arrange for output from Perl's "warn" command to be written to Exim's main
3273 log by default. The user can override this with suitable Perl magic.
3274

PH
327577. The use of log_message on a "discard" ACL verb, which is supposed to add to
3276 the log message when discard triggers, was not working for the DATA ACL or
3277 for the non-SMTP ACL.

3280
bb6e88ff
PH
328179. If smtp_accept_max_per_host was set, the number of connections could be
3282 restricted to fewer than expected, because the daemon was trying to set up
3283 a new connection before checking whether the processes handling previous
3284 connections had finished. The check for completed processes is now done
3285 earlier. On busy systems, this bug wouldn't be noticed because something
3286 else would have woken the daemon, and it would have reaped the completed
3287 process earlier.
3288

PH
328980. If a message was submitted locally by a user whose login name contained one
3290 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3291 It caused a spool format error. I have fixed the spool reading code. A
3292 related problem was that the "from" clause in the Received: line became
3293 illegal because of the space(s). It is now covered by ${quote_local_part.

3309----------------------------------------------------
3310See the note above about the 4.44 and 4.50 releases.
3311----------------------------------------------------
3312
3313
3314Exim version 4.44
3315-----------------
3316
3317 1. Change 4.43/35 introduced a bug that caused file counts to be
3318 incorrectly computed when quota_filecount was set in an appendfile
3319 transport
3320
3321 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3322 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3323 place.
3324
3325 3. Give more explanation in the error message when the command for a transport
3326 filter fails to execute.
3327
3328 4. There are several places where Exim runs a non-Exim command in a
3329 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3330 was being done only for the command run by the queryprogram router. It is
3331 now done for all such subprocesses. The other cases are: ${run, transport
3332 filters, and the commands run by the lmtp and pipe transports.
3333
3334 5. Some older OS have a limit of 256 on the maximum number of file
3335 descriptors. Exim was using setrlimit() to set 1000 as a large value
3336 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3337 systems. I've change it so that if it can't get 1000, it tries for 256.
3338
3339 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3340 was an oversight, and furthermore, ever since the addition of extra
3341 controls (e.g. 4.43/32), the checks on when to allow different forms of
3342 "control" were broken. There should now be diagnostics for all cases when a
3343 control that does not make sense is encountered.
3344
3345 7. $recipients is now available in the predata ACL (oversight).
3346
3347 8. Tidy the search cache before the fork to do a delivery from a message
3348 received from the command line. Otherwise the child will trigger a lookup
3349 failure and thereby defer the delivery if it tries to use (for example) a
3350 cached ldap connection that the parent has called unbind on.
3351
3352 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3353 of $address_data from the recipient verification was clobbered by the
3354 sender verification.
3355
335610. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3357 was its contents. (It was OK if the option was not defined at all.)
3358
335911. A "Completed" log line is now written for messages that are removed from
3360 the spool by the -Mrm option.
3361
336212. $host_address is now set to the target address during the checking of
3363 ignore_target_hosts.
3364
336513. When checking ignore_target_hosts for an ipliteral router, no host name was
3366 being passed; this would have caused $sender_host_name to have been used if
3367 matching the list had actually called for a host name (not very likely,
3368 since this list is usually IP addresses). A host name is now passed as
3369 "[x.x.x.x]".
3370
337114. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3372 code that specifies a non-restarting handler (typically sigaction() in
3373 modern systems) in an attempt to fix a rare and obscure crash bug.
3374
337515. Narrowed the window for a race in the daemon that could cause it to ignore
3376 SIGCHLD signals. This is not a major problem, because they are used only to
3377 wake it up if nothing else does.
3378
337916. A malformed maildirsize file could cause Exim to calculate negative values
3380 for the mailbox size or file count. Odd effects could occur as a result.
3381 The maildirsize information is now recalculated if the size or filecount
3382 end up negative.
3383
338417. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3385 support for a long time. Removed HAVE_SYS_VFS_H.
3386
ea3a6f44 338718. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3388
338919. Allow an empty sender to be matched against a lookup in an address list.
3390 Previously the only cases considered were a regular expression, or an
3391 empty pattern.
3392
339320. Exim went into a mad DNS lookup loop when doing a callout where the
3394 host was specified on the transport, if the DNS lookup yielded more than
3395 one IP address.
3396
ea3a6f44
NM
339721. The RFC2047 encoding function was originally intended for short strings
3398 such as real names; it was not keeping to the 75-character limit for
3399 encoded words that the RFC imposes. It now respects the limit, and
3400 generates multiple encoded words if necessary. To be on the safe side, I
3401 have increased the buffer size for the ${rfc2047: expansion operator from
3402 1024 to 2048 bytes.
bbe902f0 3403

340422. Failure to deliver a bounce message always caused it to be frozen, even if
3405 there was an errors_to setting on the router. The errors_to setting is now
3406 respected.
bbe902f0
PH
3407
340823. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3409 canonical form (fully expanded) before being placed in
3410 $sender_host_address.
