4Exim version 4.88
5-----------------
9094b84b
JH
6JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
7 supports it and a size is available (ie. the sending peer gave us one).
8d042305 8
03d5892b
JH
9JH/02 The obsolete acl condition "demime" is removed (finally, after ten
10 years of being deprecated). The replacements are the ACLs
11 acl_smtp_mime and acl_not_smtp_mime.
12
4b0fe319
JH
13JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
14 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
15 or even an in-clear connection were permitted. Now, if the host lookup
16 was dnssec and dane was requested then the host is only used if the
17 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
18 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
19 if one fails this test.
20 This means that a poorly-configured remote DNS will make it incommunicado;
21 but it protects against a DNS-interception attack on it.

JH
23JH/04 Bug 1810: make continued-use of an open smtp transport connection
24 non-noisy when a race steals the message being considered.
25
23bb6982
JH
26JH/05 If main configuration option tls_certificate is unset, generate a
27 selfsigned certificate for inbound TLS connections.
28
0bd1b1ed 29JH/06 Bug 165: hide more cases of password exposure - this time in expansions
f42deca9 30 in rewrites and routers.
0bd1b1ed 31
20b9a2dc
JH
32JH/07 Retire gnutls_require_mac et.al. These were nonfunctional since 4.80
33 and logged a warning sing 4.83; now they are a configuration file error.
34
05392bbc
JH
35JH/08 Bug 1836: Fix crash in VRFY handling when handed an unqualified name
36 (lacking @domain). Apply the same qualification processing as RCPT.
37
1a6230a3
JH
38JH/09 Bug 1804: Avoid writing msglog files when in -bh or -bhc mode.
39
cfab9d68
JH
40JH/10 Support ${sha256:} applied to a string (as well as the previous
41 certificate).
42
98c82a3d
JH
43JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
44 a cutthrough deliver is pending, as we always want to make a connection.
45 This also avoids re-routing the message when later placing the cutthrough
46 connection after a verify cache hit.
47 Do not update it with the verify result either.
48
49JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
50 when routing results in more than one destination address.
51
ae8386f0
JH
52JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
53 signing (which inhibits the cutthrough capability). Previously only
54 the presence of an option was tested; now an expansion evaluating as
55 empty is permissible (obviously it should depend only on data available
56 when the cutthrough connection is made).
57
0d9fa8c0
JH
58JH/14 Fix logging of errors under PIPELINING. Previously the log line giving
59 the relevant preceding SMTP command did not note the pipelining mode.
60
3581f321
JH
61JH/15 Fix counting of empty lines in $body_linecount and $message_linecount.
62 Previously they were not counted.
63
ef3a1a30
JH
64JH/16 DANE: treat a TLSA lookup response having all non-TLSA RRs, the same
65 as one having no matching records. Previously we deferred the message
66 that needed the lookup.
67
803628d5 68JH/17 Fakereject: previously logged as a norml message arrival "<="; now
27b9e5f4
JH
69 distinguished as "(=".
70
1435d4b2
JH
71JH/18 Bug 1867: make the fail_defer_domains option on a dnslookup router work
72 for missing MX records. Previously it only worked for missing A records.

74JH/19 Buf 1850: support Radius libraries that return REJECT_RC

77Exim version 4.87
78-----------------
82d14d6a
JH
79JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
80 and 3.4.4 - once the server is enabled to respond to an OCSP request
81 it does even when not requested, resulting in a stapling non-aware
82 client dropping the TLS connection.
0d9b78be 83

TF
84TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
85 support variable-length bit vectors. No functional change.
86
ac881e27
TF
87TF/02 Improve the consistency of logging incoming and outgoing interfaces.
88 The I= interface field on outgoing lines is now after the H= remote
89 host field, same as incoming lines. There is a separate
90 outgoing_interface log selector which allows you to disable the
91 outgoing I= field.
92
c8899c20
JH
93JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
94 If not running log_selector +smtp_connection the mainlog would be held
95 open indefinitely after a "too many connections" event, including to a
96 deleted file after a log rotate. Leave the per net connection logging
97 leaving it open for efficiency as that will be quickly detected by the
98 check on the next write.
99

HSHR
100HS/01 Bug 1671: Fix post transport crash.
101 Processing the wait-<transport> messages could crash the delivery
102 process if the message IDs didn't exist for some reason. When
103 using 'split_spool_directory=yes' the construction of the spool
104 file name failed already, exposing the same netto behaviour.
105
f38917cc
JH
106JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
107 mime_regex ACL conditions.
108

JH
109JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
110 to DSN fail messages (bounces): remote IP, remote greeting, remote response
111 to HELO, local diagnostic string.
112
805bb5c3
JH
113JH/05 Downgrade message for a TLS-certificate-based authentication fail from
114 log line to debug. Even when configured with a tls authenticator many
115 client connections are expected to not authenticate in this way, so
116 an authenticate fail is not an error.
117
56c2a7be
HSHR
118HS/02 Add the Exim version string to the process info. This way exiwhat
119 gives some more detail about the running daemon.
120

JH
121JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
122 matter for fast-change records such as DNSBLs.
123
6f6dedcc
JH
124JH/07 Bug 1678: Always record an interface option value, if set, as part of a
125 retry record, even if constant. There may be multiple transports with
126 different interface settings and the retry behaviour needs to be kept
127 distinct.
128
0f557e90
JH
129JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.
130
131JH/09 Bug 1700: ignore space & tab embedded in base64 during decode.

133JH/10 Bug 840: fix log_defer_output option of pipe transport
134
41e93589
JH
135JH/11 Bug 830: use same host for all RCPTS of a message, even under
136 hosts_randomize. This matters a lot when combined with mua_wrapper.
137
98b98887 138JH/12 Bug 1706: percent and underbar characters are no longer escaped by the
376d2ec0
JH
139 ${quote_pgsql:<string>} operator.
140
98b98887
JH
141JH/13 Bug 1708: avoid misaligned access in cached lookup.
142
858e91c2
JH
143JH/14 Change header file name for freeradius-client. Relevant if compiling
144 with Radius support; from the Gentoo tree and checked under Fedora.
145
146JH/15 Bug 1712: Introduce $prdr_requested flag variable
147
6ff55e50
JH
148JH/16 Bug 1714: Permit an empty string as expansion result for transport
149 option transport_filter, meaning no filtering.

JB
151JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
152
23f3dc67
JH
153JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
154 defaults to "*" (all hosts). The variable is now available when not built
155 with TLS, default unset, mainly to enable keeping the testuite sane.
156 If a server certificate is not supplied (via tls_certificate) an error is
157 logged, and clients will find TLS connections fail on startup. Presumably
158 they will retry in-clear.
159 Packagers of Exim are strongly encouraged to create a server certificate
160 at installation time.
161
240c288f
JH
162HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
163 with the $config_file variable.
164
5ef5dd52
JB
165JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
166 in transport context, after the attempt, and per-recipient. The latter type
167 is per host attempted. The event data is the error message, and the errno
168 information encodes the lookup type (A vs. MX) used for the (first) host,
169 and the trailing two digits of the smtp 4xx reponse.
170
e161710d
GF
171GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
172 to write to mainlog (or rejectlog, paniclog) in the window between file
173 creation and permissions/ownership being changed. Particularly affects
174 installations where exicyclog is run as root, rather than exim user;
175 result is that the running daemon panics and dies.
176

JH
177JH/20 Bug 1701: For MySQL lookups, support MySQL config file option group names.
178
7f06582c
JH
179JH/21 Bug 1720: Add support for priority groups and weighted-random proxy
180 selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
181 "pri" and "weight". Note that the previous implicit priority given by the
182 list order is no longer honoured.

190JH/26 Move PROXY support from Experimental to mainline, enabled for a build
191 by defining SUPPORT_PROXY. Note that the proxy_required_hosts option
e6d2a989
JH
192 is renamed to hosts_proxy, and the proxy_{host,target}_{address,port}.
193 variables are renamed to proxy_{local,external}_{address,port}.

f444c2c7
JH
215JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
216 support, by using OpenSSL or GnuTLS library ones. This means DKIM is
07c73177
JH
217 only supported when built with TLS support. The PolarSSL SHA routines
218 are still used when the TLS library is too old for convenient support.
f444c2c7 219
a57b6200
JH
220JH/35 Require SINGLE_DH_USE by default in OpenSSL (main config option
221 openssl_options), for security. OpenSSL forces this from version 1.1.0
222 server-side so match that on older versions.
223
07c73177 224JH/36 Bug 1778: longstanding bug in memory use by the ${run } expansion: A fresh
fa01e4f8 225 allocation for $value could be released as the expansion processing
07c73177 226 concluded, but leaving the global pointer active for it.
fa01e4f8 227

228JH/37 Bug 1769: Permit a VRFY ACL to override the default 252 response,
229 and to use the domains and local_parts ACL conditions.
230
1bc460a6
JH
231JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
232 incorrectly not doubled on cutthrough transmission, hence seen as a
233 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 234 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
235 via the normal store-and-forward channel. This could result in duplicates
236 received - but deduplicating mailstores were liable to retain only the
237 initial truncated version.

250JH/43 Tidy coding issues detected by gcc --fsanitize=undefined. Some remain;
251 either intentional arithmetic overflow during PRNG, or testing config-
252 induced overflows.

254JH/44 Bug 1800: The combination of a -bhc commandline option and cutthrough
255 delivery resulted in actual delivery. Cancel cutthrough before DATA
256 stage.

258JH/45 Fix cutthrough, when connection not opened by verify and target hard-
259 rejects a recipient: pass the reject to the originator.
260
dc8091e7
JH
261JH/46 Multiple issues raised by Coverity. Some were obvious or plausible bugs.
262 Many were false-positives and ignorable, but it's worth fixing the
263 former class.
264
dfe7d917
JH
265JH/47 Fix build on HP-UX and older Solaris, which need (un)setenv now also
266 for the new environment-manipulation done at startup. Move the routines
267 from being local to tls.c to being global via the os.c file.
268
93cc2d6e
JH
269JH/48 Bug 1807: Fix ${extract } for the numeric/3-string case. While preparsing
270 an extract embedded as result-arg for a map, the first arg for extract
271 is unavailable so we cannot tell if this is a numbered or keyed
272 extraction. Accept either.

01a4a5c5 286JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 287 is now done by default. The transport option tls_verify_cert_hostnames

JH
288 can be used to disable this per-host. The build option
289 EXPERIMENTAL_CERTNAMES is withdrawn.

JH
293 For GnuTLS, only version 3.0.20 or later.

371 Normally benign, it bites when the pair was led to by a CNAME;

403 the beginning for it to behave that way. Changed the runtest perl

763TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
764
765 When a queue runner is handling a message, Exim first routes the
766 recipient addresses, during which it prunes them based on the retry
767 hints database. After that it attempts to deliver the message to
768 any remaining recipients. It then updates the hints database using
769 the retry rules.
770
771 So if a recipient address works intermittently, it can get repeatedly
772 deferred at routing time. The retry hints record remains fresh so the
773 address never reaches the final cutoff time.
774
775 This is a fairly common occurrence when a user is bumping up against
776 their storage quota. Exim had some logic in its local delivery code
777 to deal with this. However it did not apply to per-recipient defers
778 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
779
1ddeb334
TF
780 This change adds a proper retry rule check during routing so that the
781 final cutoff time is checked against the message's age. We only do
782 this check if there is an address retry record and there is not a
783 domain retry record; this implies that previous attempts to handle
784 the address had the retry_use_local_parts option turned on. We use
785 this as an approximation for the destination being like a local
786 delivery, as in LMTP.
67bd1ab3
TF
787
788 I suspect this new check makes the old local delivery cutoff check
789 redundant, but I have not verified this so I left the code in place.

796
797 When I ran the test suite under the user fanf2, Exim expanded
798 the header to contain my full name, whereas it should have added
799 a Resent-Sender: header. It erroneously treats any prefix of the
800 username as equal to the username.

823JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
824 Server implementation by Todd Lyons, client by JH.
825 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
826 config variable "prdr_enable" controls whether the server
827 advertises the facility. If the client requests PRDR a new
828 acl_data_smtp_prdr ACL is called once for each recipient, after
829 the body content is received and before the acl_smtp_data ACL.
830 The client is controlled by bolth of: a hosts_try_prdr option
831 on the smtp transport, and the server advertisement.
832 Default client logging of deliveries and rejections involving
833 PRDR are flagged with the string "PRDR".

1111TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1112 lock up or crash if it happened to be inside a call to libc when it
1113 got a SIGUSR1 from exiwhat.
1114
1115 The SIGUSR1 handler appends the current process status to the process
1116 log which is later printed by exiwhat. It used to use the general
1117 purpose logging code to do this, but several functions it calls are
1118 not safe for signals.
1119
1120 The new output code in the SIGUSR1 handler is specific to the process
1121 log, and simple enough that it's easy to inspect for signal safety.
1122 Removing some special cases also simplifies the general logging code.
1123 Removing the spurious timestamps from the process log simplifies
1124 exiwhat.

TF
1126TF/04 Improved ratelimit ACL condition.
1127
1128 The /noupdate option has been deprecated in favour of /readonly which
1129 has clearer semantics. The /leaky, /strict, and /readonly update modes
1130 are mutually exclusive. The update mode is no longer included in the
1131 database key; it just determines when the database is updated. (This
1132 means that when you upgrde Exim will forget old rate measurements.)
1133
1134 Exim now checks that the per_* options are used with an update mode that
1135 makes sense for the current ACL. For example, when Exim is processing a
1136 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1137 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1138 must specify per_mail/readonly. If you omit the update mode it defaults to
1139 /leaky where that makes sense (as before) or /readonly where required.
1140
1141 The /noupdate option is now undocumented but still supported for
1142 backwards compatibility. It is equivalent to /readonly except that in
1143 ACLs where /readonly is required you may specify /leaky/noupdate or
1144 /strict/noupdate which are treated the same as /readonly.
1145
1146 A useful new feature is the /count= option. This is a generalization
1147 of the per_byte option, so that you can measure the throughput of other
1148 aggregate values. For example, the per_byte option is now equivalent
1149 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1150
1151 The per_rcpt option has been generalized using the /count= mechanism
1152 (though it's more complicated than the per_byte equivalence). When it is
1153 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1154 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1155 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1156 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1157 Note that using per_rcpt with a non-readonly update mode in more than
1158 one ACL will cause the recipients to be double-counted. (The per_mail
1159 and per_byte options don't have this problem.)
1160
1161 The handling of very low rates has changed slightly. If the computed rate
1162 is less than the event's count (usually one) then this event is the first
1163 after a long gap. In this case the rate is set to the same as this event's
1164 count, so that the first message of a spam run is counted properly.
1165
1166 The major new feature is a mechanism for counting the rate of unique
1167 events. The new per_addr option counts the number of different
1168 recipients that someone has sent messages to in the last time period. It
1169 behaves like per_rcpt if all the recipient addresses are different, but
1170 duplicate recipient addresses do not increase the measured rate. Like
1171 the /count= option this is a general mechanism, so the per_addr option
1172 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1173 example, measure the rate that a client uses different sender addresses
1174 with the options per_mail/unique=$sender_address. There are further
1175 details in the main documentation.

1726 were called 'true' and it seems that C99 defines that as a reserved

1747PH/01 Another patch from the Sieve maintainer.
1748
6a3bceb1
PH
1749PH/02 When an IPv6 address is converted to a string for single-key lookup
1750 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1751 dots are used instead of colons so that keys in lsearch files need not
1752 contain colons. This was done some time before quoting was made available
1753 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1754 (notated using the quote facility) so as to distinguish them from IPv4
1755 keys. This meant that lookups for IP addresses in host lists did not work
1756 for iplsearch lookups.
1757
1758 This has been fixed by arranging for IPv6 addresses to be expressed with
1759 colons if the lookup type is iplsearch. This is not incompatible, because
1760 previously such lookups could never work.
1761
1762 The situation is now rather anomolous, since one *can* have colons in
1763 ordinary lsearch keys. However, making the change in all cases is
1764 incompatible and would probably break a number of configurations.

1769MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1770 conversion specification without a maximum field width, thereby enabling
1771 a rogue spamd server to cause a buffer overflow. While nobody in their
1772 right mind would setup Exim to query an untrusted spamd server, an
1773 attacker that gains access to a server running spamd could potentially
1774 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1779MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1780 a directory entry by the name of the lookup key. Previously, if a
1781 symlink pointed to a non-existing file or a file in a directory that
1782 Exim lacked permissions to read, a lookup for a key matching that
1783 symlink would fail. Now it is enough that a matching directory entry
1784 exists, symlink or not. (Bugzilla 503.)

1861 if a client was not listed at all, or was listed with a value other than

1967PH/29 SMTP synchronization checks are implemented when a command is read -
1968 there is a check that no more input is waiting when there shouldn't be
1969 any. However, for some commands, a delay in an ACL can mean that it is
1970 some time before the response is written. In this time, more input might
1971 arrive, invalidly. So now there are extra checks after an ACL has run for
1972 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1973 pipelining has not been advertised.

2047 the response to the final '.' that terminates a message, but only in the
2048 case where the client has not sent further data following the '.'
2049 (unfortunately, this is allowed). However, in many cases there won't be
2050 any further data because there won't be any more messages to send. A call
2051 to select() can be used: if it shows that the input is "ready", there is
2052 either input waiting, or the socket has been closed. An attempt to read
2053 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2054 would have sent an OK response which the client would never have see.

2064
2065PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2066 fixed by 4.65/MH/01 (is this a record?) are fixed:
2067
2068 (i) An empty string was always treated as zero by the numeric comparison
2069 operators. This behaviour has been restored.
2070
2071 (ii) It is documented that the numeric comparison operators always treat
2072 their arguments as decimal numbers. This was broken in that numbers
2073 starting with 0 were being interpreted as octal.
2074
2075 While fixing these problems I realized that there was another issue that
2076 hadn't been noticed. Values of message_size_limit (both the global option
2077 and the transport option) were treated as octal if they started with 0.
2078 The documentation was vague. These values are now always treated as
2079 decimal, and I will make that clear in the documentation.

2096 large number of recipients for a single message is ridiculous

PH
2123PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2124 callout verification, Exim cached a "reject" for the entire domain. This
2125 is correct for most verifications, but it is not correct for a recipient
2126 verification with use_sender or use_postmaster set, because in that case
2127 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2128 case of MAIL FROM:<> rejection from other early rejections (e.g.
2129 rejection of HELO). When verifying a recipient using a non-null MAIL
2130 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2131 Whatever the result of the callout, the value of the domain cache is
2132 left unchanged (for any other kind of callout, getting as far as trying
2133 RCPT means that the domain itself is ok).

2167PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2169 probably the interface on which it is arriving) and not to the outgoing
2170 callout (which could be using a different interface). This has been
2171 changed to use the value of the helo_data option from the smtp transport
2172 instead - this is what is used when a message is actually being sent. If
2173 there is no remote transport (possible with a router that sets up host
2174 addresses), $smtp_active_hostname is used.

7befa435 2177 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2178 (a) The code assumed that strncpy() returns a negative number on buffer
2179 overflow, which isn't the case. Replaced with Exim's string_format()
2180 function.
2181 (b) There were several signed/unsigned issues. I just did the minimum
2182 hacking in of casts. There is scope for a larger refactoring.
2183 (c) The code used strcasecmp() which is not a standard C function.
2184 Replaced with Exim's strcmpic() function.
2185 (d) The code set only $1; it now sets $auth1 as well.
2186 (e) A simple test gave the error "authentication client didn't specify
2187 service in request". It would seem that Dovecot has changed its
2188 interface. Fortunately there's a specification; I followed it and
2189 changed what the client sends and it appears to be working now.

2195 address A is aliased to B and C, where B exists and C does not. Without
2196 -v the output is "A verified" because verification stops after a
2197 successful redirection if more than one address is generated. However,
2198 with -v the child addresses are also verified. Exim was outputting "A
2199 failed to verify" and then showing the successful verification for C,
2200 with its parentage. It now outputs "B failed to verify", showing B's
2201 parentage before showing the successful verification of C.

322050c2
PH
2207PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2208 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2209 they consult the DNS. I had assumed they would set it the way they
2210 wanted; and indeed my experiments on Linux seem to show that in some
2211 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2212 To be on the safe side, however, I have now made the interface to
2213 host_find_byname() similar to host_find_bydns(), with an argument
2214 containing the DNS resolver options. The host_find_byname() function now
2215 sets these options at its start, just as host_find_bydns() does. The smtp
2216 transport options dns_qualify_single and dns_search_parents are passed to
2217 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2218 of host_find_byname() use the default settings of RES_DEFNAMES
2219 (qualify_single) but not RES_DNSRCH (search_parents).

2222 spool_read_header() do less string testing, by means of a preliminary
2223 switch on the second character of optional "-foo" lines. (This is
2224 overdue, caused by the large number of possibilities that now exist.
2225 Originally there were few.) While I was there, I also converted the
2226 str(n)cmp tests so they don't re-test the leading "-" and the first
2227 character, in the hope this might squeeze out yet more improvement.

2229PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2230 flag allowing group syntax was set by the header_syntax check but not
2231 turned off, possible causing trouble later; (2) The flag was not being
2232 set at all for the header_verify test, causing "group"-style headers to
2233 be rejected. I have now set it in this case, and also caused header_
2234 verify to ignore an empty address taken from a group. While doing this, I
2235 came across some other cases where the code for allowing group syntax
2236 while scanning a header line wasn't quite right (mostly, not resetting
2237 the flag correctly in the right place). These bugs could have caused
2238 trouble for malformed header lines. I hope it is now all correct.

2240PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

2243 but it didn't always do it. This confused somebody who was copying the
2244 code for some other use. I have removed all the tests.

PH
2246PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2247 feature that was used to support insecure browsers during the U.S. crypto
2248 embargo. It requires special client support, and Exim is probably the
2249 only MTA that supported it -- and would never use it because real RSA is
2250 always available. This code has been removed, because it had the bad
2251 effect of slowing Exim down by computing (never used) parameters for the
2252 RSA_EXPORT functionality.

2257 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2258 if the connection is using TLS or if the remote IP is the same as the
2259 local IP, and the "valid-client-cert option" if a client certificate has
2260 been verified.

PH
2291
2292PH/30 Exim was sometimes attempting to deliver messages that had suffered
2293 address errors (4xx response to RCPT) over the same connection as other
2294 messages routed to the same hosts. Such deliveries are always "forced",
2295 so retry times are not inspected. This resulted in far too many retries
2296 for the affected addresses. The effect occurred only when there were more
2297 hosts than the hosts_max_try setting in the smtp transport when it had
2298 the 4xx errors. Those hosts that it had tried were not added to the list
2299 of hosts for which the message was waiting, so if all were tried, there
2300 was no problem. Two fixes have been applied:
2301
2302 (i) If there are any address or message errors in an SMTP delivery, none
2303 of the hosts (tried or untried) are now added to the list of hosts
2304 for which the message is waiting, so the message should not be a
2305 candidate for sending over the same connection that was used for a
2306 successful delivery of some other message. This seems entirely
2307 reasonable: after all the message is NOT "waiting for some host".
2308 This is so "obvious" that I'm not sure why it wasn't done
2309 previously. Hope I haven't missed anything, but it can't do any
2310 harm, as the worst effect is to miss an optimization.
2311
2312 (ii) If, despite (i), such a delivery is accidentally attempted, the
2313 routing retry time is respected, so at least it doesn't keep
2314 hammering the server.

2329PH/35 The error "getsockname() failed: connection reset by peer" was being
2330 written to the panic log as well as the main log, but it isn't really
2331 panic-worthy as it just means the connection died rather early on. I have
2332 removed the panic log writing for the ECONNRESET error when getsockname()
2333 fails.

2335PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2336 runs only) independently of the message's sender address. This meant
2337 that, if the 4xx error was in fact related to the sender, a different
2338 message to the same recipient with a different sender could confuse
2339 things. In particualar, this can happen when sending to a greylisting
2340 server, but other circumstances could also provoke similar problems.
2341 I have changed the default so that the retry time for these errors is now
2342 based a combination of the sender and recipient addresses. This change
2343 can be overridden by setting address_retry_include_sender=false in the
2344 smtp transport.

2615 tcp-wrappers gives "deny", whereas what one would like would be some
2616 kind of temporary error. A kludge has been added to help with this.
2617 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2618 554 error is used if errno is still zero or contains ENOENT (which occurs
2619 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2722PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
2723 used if the router is not running as root, for example, when verifying at
2724 ACL time, or when using -bh. The debugging output from this situation was
2725 non-existent - all you got was a failure to exec. I have made two
2726 changes:
2727
2728 (a) Failures to set uid/gid, the current directory, or a process leader
2729 in a subprocess such as that created by queryprogram now generate
2730 suitable debugging ouput when -d is set.
2731
2732 (b) The queryprogram router detects when it is not running as root,
2733 outputs suitable debugging information if -d is set, and then runs
2734 the subprocess without attempting to change uid/gid.

2739PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2740 additional section of a DNS packet that returns MX or SRV records.
2741 Instead, it always explicitly searches for A/AAAA records. This avoids
2742 major problems that occur when a DNS server includes only records of one
2743 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2744 fixed another bug: if SRV records were looked up and the corresponding
2745 address records were *not* found in the additional section, the port
2746 values from the SRV records were lost.

PH
2756PH/19 When calculating a retry time, Exim used to measure the "time since
2757 failure" by looking at the "first failed" field in the retry record. Now
2758 it does not use this if it is later than than the arrival time of the
2759 message. Instead it uses the arrival time. This makes for better
2760 behaviour in cases where some deliveries succeed, thus re-setting the
2761 "first failed" field. An example is a quota failure for a huge message
2762 when small messages continue to be delivered. Without this change, the
2763 "time since failure" will always be short, possible causing more frequent
2764 delivery attempts for the huge message than are intended.

PH
2861PH/42 The content-scanning code uses fopen() to create files in which to put
2862 message data. Previously it was not paying any attention to the mode of
2863 the files. Exim runs with umask(0) because the rest of the code creates
2864 files with open(), and sets the required mode explicitly. Thus, these
2865 files were ending up world-writeable. This was not a big issue, because,
2866 being within the spool directory, they were not world-accessible. I have
2867 created a function called modefopen, which takes an additional mode
2868 argument. It sets umask(777), creates the file, chmods it to the required
2869 mode, then resets the umask. All the relevant calls to fopen() in the
2870 content scanning code have been changed to use this function.

2881 received. Setting client_ignore_invalid_base64 true ignores these errors.
2882 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2883 they are received. Thus, the responses can be made to depend on the

2907
2908 (i) Exim was not creating retry information for temporary errors given
2909 for individual recipients after the DATA command when the smtp transport
2910 was used in LMTP mode. This meant that they could be retried too
2911 frequently, and not timed out correctly.
2912
2913 (ii) Exim was setting the flag that allows error details to be returned
2914 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2915 recipients that were returned after the DATA command.
2916
2917PH/53 This is related to PH/52, but is more general: for any failing address,
2918 when detailed error information was permitted to be returned to the
2919 sender, but the error was temporary, then after the final timeout, only
2920 "retry timeout exceeded" was returned. Now it returns the full error as

2991PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2992 function verify_get_ident() calls ip_connect() to connect a socket, but
2993 if the "connect()" function timed out, ip_connect() used to close the
2994 socket. However, verify_get_ident() also closes the socket later, and in
2995 between Exim writes to the log, which may get opened at this point. When
2996 the socket was closed in ip_connect(), the log could get the same file
2997 descriptor number as the socket. This naturally causes chaos. The fix is
2998 not to close the socket in ip_connect(); the socket should be closed by
2999 the function that creates it. There was only one place in the code where
3000 this was missing, in the iplookup router, which I don't think anybody now
3001 uses, but I've fixed it anyway.

3062
3063 Received: from [1.2.3.4] (helo=[1.2.3.4])

3141PH/17 A further patch from the Sieve maintainer: "Introduce the new Sieve
3142 extension "envelope-auth". The code is finished and in agreement with
3143 other implementations, but there is no documentation so far and in fact,
3144 nobody wrote the draft yet. This extension is currently #undef'ed, thus
3145 not changing the active code.
3146
3147 Print executed "if" and "elsif" statements when debugging is used. This
3148 helps a great deal to understand what a filter does.

PH
3156PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
3157 canonical form (as documented). However, after a host name lookup from
3158 the IP address, check_host() was doing a simple string comparison with
3159 addresses acquired from the DNS when checking that the found name did
3160 have the original IP as one of its addresses. Since any found IPv6
3161 addresses are likely to be in abbreviated form, the comparison could
3162 fail. Luckily, there already exists a function for doing the comparison
3163 by converting both addresses to binary, so now that is used instead of
3164 the text comparison.
3165
96776534
PH
3166PH/20 There was another similar case to PH/19, when a complete host name was
3167 given in a host list; looking up its IP address could give an abbreviated
3168 form, whereas the current host's name might or might not be abbreviated.
3169 The same fix has been applied.

3248PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
3249 only if the host matched helo_try_verify_hosts, which caused the

3251 tested the remembered result. Now, if a previous verification attempt has
3252 not happened, "verify = helo" does it there and then.

3281PH/23 Applied a patch to fix problems with exim-4.52 while doing radius

3283

3285 - Username/password not passed on to radius server due to wrong length.

3287 The presumption is that some radiusclient API changes for 4.51/PH/17
3288 were not taken care of correctly. The code is still untested by me (my
3289 Linux distribution still has 0.3.2 of radiusclient), but it was
