5-------------------
6JH/01 Bug 1922: Support IDNA2008. This has slightly different conversion rules
7 than -2003 did; needs libidn2 in addition to linidn.

JH
13-----------------
14JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
15 supports it and a size is available (ie. the sending peer gave us one).
16
4fab92fb
HSHR
17JH/02 The obsolete acl condition "demime" is removed (finally, after ten
18 years of being deprecated). The replacements are the ACLs
19 acl_smtp_mime and acl_not_smtp_mime.
20
21JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
22 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
23 or even an in-clear connection were permitted. Now, if the host lookup
24 was dnssec and dane was requested then the host is only used if the
25 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
26 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
27 if one fails this test.
28 This means that a poorly-configured remote DNS will make it incommunicado;
29 but it protects against a DNS-interception attack on it.
30
31JH/04 Bug 1810: make continued-use of an open smtp transport connection
32 non-noisy when a race steals the message being considered.
33
34JH/05 If main configuration option tls_certificate is unset, generate a
35 self-signed certificate for inbound TLS connections.
36
37JH/06 Bug 165: hide more cases of password exposure - this time in expansions
38 in rewrites and routers.
39
40JH/07 Retire gnutls_require_mac et.al. These were nonfunctional since 4.80
41 and logged a warning sing 4.83; now they are a configuration file error.
42
43JH/08 Bug 1836: Fix crash in VRFY handling when handed an unqualified name
44 (lacking @domain). Apply the same qualification processing as RCPT.
45
46JH/09 Bug 1804: Avoid writing msglog files when in -bh or -bhc mode.
47
48JH/10 Support ${sha256:} applied to a string (as well as the previous
49 certificate).
50
51JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
52 a cutthrough deliver is pending, as we always want to make a connection.
53 This also avoids re-routing the message when later placing the cutthrough
54 connection after a verify cache hit.
55 Do not update it with the verify result either.
56
57JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
58 when routing results in more than one destination address.
59
60JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
61 signing (which inhibits the cutthrough capability). Previously only
62 the presence of an option was tested; now an expansion evaluating as
63 empty is permissible (obviously it should depend only on data available
64 when the cutthrough connection is made).
65
66JH/14 Fix logging of errors under PIPELINING. Previously the log line giving
67 the relevant preceding SMTP command did not note the pipelining mode.
68
69JH/15 Fix counting of empty lines in $body_linecount and $message_linecount.
70 Previously they were not counted.
71
72JH/16 DANE: treat a TLSA lookup response having all non-TLSA RRs, the same
73 as one having no matching records. Previously we deferred the message
74 that needed the lookup.
75
76JH/17 Fakereject: previously logged as a norml message arrival "<="; now
77 distinguished as "(=".
78
79JH/18 Bug 1867: make the fail_defer_domains option on a dnslookup router work
80 for missing MX records. Previously it only worked for missing A records.
81
82JH/19 Bug 1850: support Radius libraries that return REJECT_RC.
83
84JH/20 Bug 1872: Ensure that acl_smtp_notquit is run when the connection drops
85 after the data-go-ahead and data-ack. Patch from Jason Betts.
86
87JH/21 Bug 1846: Send DMARC forensic reports for reject and quaratine results,
88 even for a "none" policy. Patch from Tony Meyer.
89
90JH/22 Fix continued use of a connection for further deliveries. If a port was
91 specified by a router, it must also match for the delivery to be
92 compatible.
93
94JH/23 Bug 1874: fix continued use of a connection for further deliveries.
95 When one of the recipients of a message was unsuitable for the connection
96 (has no matching addresses), we lost track of needing to mark it
97 deferred. As a result mail would be lost.
98
99JH/24 Bug 1832: Log EHLO response on getting conn-close response for HELO.
100
101JH/25 Decoding ACL controls is now done using a binary search; the source code
102 takes up less space and should be simpler to maintain. Merge the ACL
103 condition decode tables also, with similar effect.
104
105JH/26 Fix problem with one_time used on a redirect router which returned the
106 parent address unchanged. A retry would see the parent address marked as
107 delivered, so not attempt the (identical) child. As a result mail would
108 be lost.
109
110JH/27 Fix a possible security hole, wherein a process operating with the Exim
111 UID can gain a root shell. Credit to http://www.halfdog.net/ for
112 discovery and writeup. Ubuntu bug 1580454; no bug raised against Exim
113 itself :(
114
115JH/28 Enable {spool,log} filesystem space and inode checks as default.
116 Main config options check_{log,spool}_{inodes,space} are now
117 100 inodes, 10MB unless set otherwise in the configuration.
118
119JH/29 Fix the connection_reject log selector to apply to the connect ACL.
120 Previously it only applied to the main-section connection policy
121 options.
122
123JH/30 Bug 1897: fix callouts connection fallback from TLS to cleartext.
124
125PP/01 Changed default Diffie-Hellman parameters to be Exim-specific, created
126 by me. Added RFC7919 DH primes as an alternative.
127
128PP/02 Unbreak build via pkg-config with new hash support when crypto headers
129 are not in the system include path.
130
131JH/31 Fix longstanding bug with aborted TLS server connection handling. Under
132 GnuTLS, when a session startup failed (eg because the client disconnected)
133 Exim did stdio operations after fclose. This was exposed by a recent
134 change which nulled out the file handle after the fclose.
135
136JH/32 Bug 1909: Fix OCSP proof verification for cases where the proof is
137 signed directly by the cert-signing cert, rather than an intermediate
138 OCSP-signing cert. This is the model used by LetsEncrypt.
139
140JH/33 Bug 1914: Ensure socket is nonblocking before draining after SMTP QUIT.

143Exim version 4.87
144-----------------
82d14d6a
JH
145JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
146 and 3.4.4 - once the server is enabled to respond to an OCSP request
147 it does even when not requested, resulting in a stapling non-aware
148 client dropping the TLS connection.

150TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
151 support variable-length bit vectors. No functional change.
152
ac881e27
TF
153TF/02 Improve the consistency of logging incoming and outgoing interfaces.
154 The I= interface field on outgoing lines is now after the H= remote
155 host field, same as incoming lines. There is a separate
156 outgoing_interface log selector which allows you to disable the
157 outgoing I= field.
158
c8899c20
JH
159JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
160 If not running log_selector +smtp_connection the mainlog would be held
161 open indefinitely after a "too many connections" event, including to a
162 deleted file after a log rotate. Leave the per net connection logging
163 leaving it open for efficiency as that will be quickly detected by the
164 check on the next write.
165

HSHR
166HS/01 Bug 1671: Fix post transport crash.
167 Processing the wait-<transport> messages could crash the delivery
168 process if the message IDs didn't exist for some reason. When
169 using 'split_spool_directory=yes' the construction of the spool
170 file name failed already, exposing the same netto behaviour.
171

JH
172JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
173 mime_regex ACL conditions.

JH
175JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
176 to DSN fail messages (bounces): remote IP, remote greeting, remote response
177 to HELO, local diagnostic string.
178
805bb5c3
JH
179JH/05 Downgrade message for a TLS-certificate-based authentication fail from
180 log line to debug. Even when configured with a tls authenticator many
181 client connections are expected to not authenticate in this way, so
182 an authenticate fail is not an error.
183
56c2a7be
HSHR
184HS/02 Add the Exim version string to the process info. This way exiwhat
185 gives some more detail about the running daemon.
186

JH
187JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
188 matter for fast-change records such as DNSBLs.
189
6f6dedcc
JH
190JH/07 Bug 1678: Always record an interface option value, if set, as part of a
191 retry record, even if constant. There may be multiple transports with
192 different interface settings and the retry behaviour needs to be kept
193 distinct.

195JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.

201JH/11 Bug 830: use same host for all RCPTS of a message, even under
202 hosts_randomize. This matters a lot when combined with mua_wrapper.
203
98b98887 204JH/12 Bug 1706: percent and underbar characters are no longer escaped by the
376d2ec0
JH
205 ${quote_pgsql:<string>} operator.

209JH/14 Change header file name for freeradius-client. Relevant if compiling
210 with Radius support; from the Gentoo tree and checked under Fedora.

218
23f3dc67
JH
219JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
220 defaults to "*" (all hosts). The variable is now available when not built
221 with TLS, default unset, mainly to enable keeping the testuite sane.
222 If a server certificate is not supplied (via tls_certificate) an error is
223 logged, and clients will find TLS connections fail on startup. Presumably
224 they will retry in-clear.
225 Packagers of Exim are strongly encouraged to create a server certificate
226 at installation time.
227
240c288f
JH
228HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
229 with the $config_file variable.
230
5ef5dd52
JB
231JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
232 in transport context, after the attempt, and per-recipient. The latter type
233 is per host attempted. The event data is the error message, and the errno
234 information encodes the lookup type (A vs. MX) used for the (first) host,
235 and the trailing two digits of the smtp 4xx reponse.
236

GF
237GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
238 to write to mainlog (or rejectlog, paniclog) in the window between file
239 creation and permissions/ownership being changed. Particularly affects
240 installations where exicyclog is run as root, rather than exim user;
241 result is that the running daemon panics and dies.

246 selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
247 "pri" and "weight". Note that the previous implicit priority given by the
248 list order is no longer honoured.

f444c2c7
JH
281JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
282 support, by using OpenSSL or GnuTLS library ones. This means DKIM is
07c73177
JH
283 only supported when built with TLS support. The PolarSSL SHA routines
284 are still used when the TLS library is too old for convenient support.
f444c2c7 285
a57b6200
JH
286JH/35 Require SINGLE_DH_USE by default in OpenSSL (main config option
287 openssl_options), for security. OpenSSL forces this from version 1.1.0
288 server-side so match that on older versions.
289
07c73177 290JH/36 Bug 1778: longstanding bug in memory use by the ${run } expansion: A fresh
fa01e4f8 291 allocation for $value could be released as the expansion processing
07c73177 292 concluded, but leaving the global pointer active for it.
fa01e4f8 293

294JH/37 Bug 1769: Permit a VRFY ACL to override the default 252 response,
295 and to use the domains and local_parts ACL conditions.
296
1bc460a6
JH
297JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
298 incorrectly not doubled on cutthrough transmission, hence seen as a
299 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 300 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
301 via the normal store-and-forward channel. This could result in duplicates
302 received - but deduplicating mailstores were liable to retain only the
303 initial truncated version.

308
309JH/41 Bug 1792: Fix selection of headers to sign for DKIM: bottom-up. While
310 we're in there, support oversigning also; bug 1309.
311
312JH/42 Bug 1796: Fix error logged on a malware scanner connection failure.
313
314HS/04 Add support for keep_environment and add_environment options.
315
316JH/43 Tidy coding issues detected by gcc --fsanitize=undefined. Some remain;
317 either intentional arithmetic overflow during PRNG, or testing config-
318 induced overflows.
319
320JH/44 Bug 1800: The combination of a -bhc commandline option and cutthrough
321 delivery resulted in actual delivery. Cancel cutthrough before DATA
322 stage.
323
324JH/45 Fix cutthrough, when connection not opened by verify and target hard-
325 rejects a recipient: pass the reject to the originator.
326
327JH/46 Multiple issues raised by Coverity. Some were obvious or plausible bugs.
328 Many were false-positives and ignorable, but it's worth fixing the
329 former class.
330
331JH/47 Fix build on HP-UX and older Solaris, which need (un)setenv now also
332 for the new environment-manipulation done at startup. Move the routines
333 from being local to tls.c to being global via the os.c file.
334
335JH/48 Bug 1807: Fix ${extract } for the numeric/3-string case. While preparsing
336 an extract embedded as result-arg for a map, the first arg for extract
337 is unavailable so we cannot tell if this is a numbered or keyed
338 extraction. Accept either.

470 script to read through the entire script once to detect and set these
471 variables, reset to the beginning of the script, and then run through
472 the script parsing/test process like normal.

829TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
830
831 When a queue runner is handling a message, Exim first routes the
832 recipient addresses, during which it prunes them based on the retry
833 hints database. After that it attempts to deliver the message to
834 any remaining recipients. It then updates the hints database using
835 the retry rules.
836
837 So if a recipient address works intermittently, it can get repeatedly
838 deferred at routing time. The retry hints record remains fresh so the
839 address never reaches the final cutoff time.
840
841 This is a fairly common occurrence when a user is bumping up against
842 their storage quota. Exim had some logic in its local delivery code
843 to deal with this. However it did not apply to per-recipient defers
844 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
845
1ddeb334
TF
846 This change adds a proper retry rule check during routing so that the
847 final cutoff time is checked against the message's age. We only do
848 this check if there is an address retry record and there is not a
849 domain retry record; this implies that previous attempts to handle
850 the address had the retry_use_local_parts option turned on. We use
851 this as an approximation for the destination being like a local
852 delivery, as in LMTP.
67bd1ab3
TF
853
854 I suspect this new check makes the old local delivery cutoff check
855 redundant, but I have not verified this so I left the code in place.

862
863 When I ran the test suite under the user fanf2, Exim expanded
864 the header to contain my full name, whereas it should have added
865 a Resent-Sender: header. It erroneously treats any prefix of the
866 username as equal to the username.

890 Server implementation by Todd Lyons, client by JH.
891 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
892 config variable "prdr_enable" controls whether the server
893 advertises the facility. If the client requests PRDR a new
894 acl_data_smtp_prdr ACL is called once for each recipient, after
895 the body content is received and before the acl_smtp_data ACL.
896 The client is controlled by bolth of: a hosts_try_prdr option
897 on the smtp transport, and the server advertisement.
898 Default client logging of deliveries and rejections involving
899 PRDR are flagged with the string "PRDR".

1177TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1178 lock up or crash if it happened to be inside a call to libc when it
1179 got a SIGUSR1 from exiwhat.
1180
1181 The SIGUSR1 handler appends the current process status to the process
1182 log which is later printed by exiwhat. It used to use the general
1183 purpose logging code to do this, but several functions it calls are
1184 not safe for signals.
1185
1186 The new output code in the SIGUSR1 handler is specific to the process
1187 log, and simple enough that it's easy to inspect for signal safety.
1188 Removing some special cases also simplifies the general logging code.
1189 Removing the spurious timestamps from the process log simplifies
1190 exiwhat.
1191

TF
1192TF/04 Improved ratelimit ACL condition.
1193
1194 The /noupdate option has been deprecated in favour of /readonly which
1195 has clearer semantics. The /leaky, /strict, and /readonly update modes
1196 are mutually exclusive. The update mode is no longer included in the
1197 database key; it just determines when the database is updated. (This
1198 means that when you upgrde Exim will forget old rate measurements.)
1199
1200 Exim now checks that the per_* options are used with an update mode that
1201 makes sense for the current ACL. For example, when Exim is processing a
1202 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1203 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1204 must specify per_mail/readonly. If you omit the update mode it defaults to
1205 /leaky where that makes sense (as before) or /readonly where required.
1206
1207 The /noupdate option is now undocumented but still supported for
1208 backwards compatibility. It is equivalent to /readonly except that in
1209 ACLs where /readonly is required you may specify /leaky/noupdate or
1210 /strict/noupdate which are treated the same as /readonly.
1211
1212 A useful new feature is the /count= option. This is a generalization
1213 of the per_byte option, so that you can measure the throughput of other
1214 aggregate values. For example, the per_byte option is now equivalent
1215 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1216
1217 The per_rcpt option has been generalized using the /count= mechanism
1218 (though it's more complicated than the per_byte equivalence). When it is
1219 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1220 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1221 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1222 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1223 Note that using per_rcpt with a non-readonly update mode in more than
1224 one ACL will cause the recipients to be double-counted. (The per_mail
1225 and per_byte options don't have this problem.)
1226
1227 The handling of very low rates has changed slightly. If the computed rate
1228 is less than the event's count (usually one) then this event is the first
1229 after a long gap. In this case the rate is set to the same as this event's
1230 count, so that the first message of a spam run is counted properly.
1231
1232 The major new feature is a mechanism for counting the rate of unique
1233 events. The new per_addr option counts the number of different
1234 recipients that someone has sent messages to in the last time period. It
1235 behaves like per_rcpt if all the recipient addresses are different, but
1236 duplicate recipient addresses do not increase the measured rate. Like
1237 the /count= option this is a general mechanism, so the per_addr option
1238 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1239 example, measure the rate that a client uses different sender addresses
1240 with the options per_mail/unique=$sender_address. There are further
1241 details in the main documentation.

1792 were called 'true' and it seems that C99 defines that as a reserved

1813PH/01 Another patch from the Sieve maintainer.
1814
6a3bceb1
PH
1815PH/02 When an IPv6 address is converted to a string for single-key lookup
1816 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1817 dots are used instead of colons so that keys in lsearch files need not
1818 contain colons. This was done some time before quoting was made available
1819 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1820 (notated using the quote facility) so as to distinguish them from IPv4
1821 keys. This meant that lookups for IP addresses in host lists did not work
1822 for iplsearch lookups.
1823
1824 This has been fixed by arranging for IPv6 addresses to be expressed with
1825 colons if the lookup type is iplsearch. This is not incompatible, because
1826 previously such lookups could never work.
1827
1828 The situation is now rather anomolous, since one *can* have colons in
1829 ordinary lsearch keys. However, making the change in all cases is
1830 incompatible and would probably break a number of configurations.

1835MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1836 conversion specification without a maximum field width, thereby enabling
1837 a rogue spamd server to cause a buffer overflow. While nobody in their
1838 right mind would setup Exim to query an untrusted spamd server, an
1839 attacker that gains access to a server running spamd could potentially
1840 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1845MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1846 a directory entry by the name of the lookup key. Previously, if a
1847 symlink pointed to a non-existing file or a file in a directory that
1848 Exim lacked permissions to read, a lookup for a key matching that
1849 symlink would fail. Now it is enough that a matching directory entry
1850 exists, symlink or not. (Bugzilla 503.)

2033PH/29 SMTP synchronization checks are implemented when a command is read -
2034 there is a check that no more input is waiting when there shouldn't be

2036 some time before the response is written. In this time, more input might
2037 arrive, invalidly. So now there are extra checks after an ACL has run for
2038 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2039 pipelining has not been advertised.

PH
2113 the response to the final '.' that terminates a message, but only in the
2114 case where the client has not sent further data following the '.'
2115 (unfortunately, this is allowed). However, in many cases there won't be
2116 any further data because there won't be any more messages to send. A call
2117 to select() can be used: if it shows that the input is "ready", there is
2118 either input waiting, or the socket has been closed. An attempt to read
2119 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2120 would have sent an OK response which the client would never have see.

2131PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2132 fixed by 4.65/MH/01 (is this a record?) are fixed:
2133
2134 (i) An empty string was always treated as zero by the numeric comparison
2135 operators. This behaviour has been restored.
2136
2137 (ii) It is documented that the numeric comparison operators always treat
2138 their arguments as decimal numbers. This was broken in that numbers
2139 starting with 0 were being interpreted as octal.
2140
2141 While fixing these problems I realized that there was another issue that
2142 hadn't been noticed. Values of message_size_limit (both the global option
2143 and the transport option) were treated as octal if they started with 0.
2144 The documentation was vague. These values are now always treated as
2145 decimal, and I will make that clear in the documentation.

2161 is held in a short int, deliveries were likely to be lost. As such a
2162 large number of recipients for a single message is ridiculous
2163 (performance will be very, very poor), I have chosen to impose a limit
2164 rather than extend the field.

2b1c6e3a
PH
2189PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2190 callout verification, Exim cached a "reject" for the entire domain. This
2191 is correct for most verifications, but it is not correct for a recipient
2192 verification with use_sender or use_postmaster set, because in that case
2193 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2194 case of MAIL FROM:<> rejection from other early rejections (e.g.
2195 rejection of HELO). When verifying a recipient using a non-null MAIL
2196 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2197 Whatever the result of the callout, the value of the domain cache is
2198 left unchanged (for any other kind of callout, getting as far as trying
2199 RCPT means that the domain itself is ok).

2233PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2235 probably the interface on which it is arriving) and not to the outgoing
2236 callout (which could be using a different interface). This has been
2237 changed to use the value of the helo_data option from the smtp transport
2238 instead - this is what is used when a message is actually being sent. If
2239 there is no remote transport (possible with a router that sets up host
2240 addresses), $smtp_active_hostname is used.

7befa435 2243 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2244 (a) The code assumed that strncpy() returns a negative number on buffer
2245 overflow, which isn't the case. Replaced with Exim's string_format()
2246 function.
2247 (b) There were several signed/unsigned issues. I just did the minimum
2248 hacking in of casts. There is scope for a larger refactoring.
2249 (c) The code used strcasecmp() which is not a standard C function.
2250 Replaced with Exim's strcmpic() function.
2251 (d) The code set only $1; it now sets $auth1 as well.
2252 (e) A simple test gave the error "authentication client didn't specify
2253 service in request". It would seem that Dovecot has changed its
2254 interface. Fortunately there's a specification; I followed it and
2255 changed what the client sends and it appears to be working now.

2261 address A is aliased to B and C, where B exists and C does not. Without
2262 -v the output is "A verified" because verification stops after a
2263 successful redirection if more than one address is generated. However,
2264 with -v the child addresses are also verified. Exim was outputting "A
2265 failed to verify" and then showing the successful verification for C,
2266 with its parentage. It now outputs "B failed to verify", showing B's
2267 parentage before showing the successful verification of C.

2270 look up a TXT record in a specific list after matching in a combined

2272
322050c2
PH
2273PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2274 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2275 they consult the DNS. I had assumed they would set it the way they
2276 wanted; and indeed my experiments on Linux seem to show that in some
2277 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2278 To be on the safe side, however, I have now made the interface to
2279 host_find_byname() similar to host_find_bydns(), with an argument
2280 containing the DNS resolver options. The host_find_byname() function now
2281 sets these options at its start, just as host_find_bydns() does. The smtp
2282 transport options dns_qualify_single and dns_search_parents are passed to
2283 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2284 of host_find_byname() use the default settings of RES_DEFNAMES
2285 (qualify_single) but not RES_DNSRCH (search_parents).

2287PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2288 spool_read_header() do less string testing, by means of a preliminary
2289 switch on the second character of optional "-foo" lines. (This is
2290 overdue, caused by the large number of possibilities that now exist.
2291 Originally there were few.) While I was there, I also converted the
2292 str(n)cmp tests so they don't re-test the leading "-" and the first
2293 character, in the hope this might squeeze out yet more improvement.

2295PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2296 flag allowing group syntax was set by the header_syntax check but not
2297 turned off, possible causing trouble later; (2) The flag was not being
2298 set at all for the header_verify test, causing "group"-style headers to
2299 be rejected. I have now set it in this case, and also caused header_
2300 verify to ignore an empty address taken from a group. While doing this, I
2301 came across some other cases where the code for allowing group syntax
2302 while scanning a header line wasn't quite right (mostly, not resetting
2303 the flag correctly in the right place). These bugs could have caused
2304 trouble for malformed header lines. I hope it is now all correct.

PH
2306PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

2308 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2309 but it didn't always do it. This confused somebody who was copying the
2310 code for some other use. I have removed all the tests.

PH
2312PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2313 feature that was used to support insecure browsers during the U.S. crypto
2314 embargo. It requires special client support, and Exim is probably the
2315 only MTA that supported it -- and would never use it because real RSA is
2316 always available. This code has been removed, because it had the bad
2317 effect of slowing Exim down by computing (never used) parameters for the
2318 RSA_EXPORT functionality.

2324 if the connection is using TLS or if the remote IP is the same as the
2325 local IP, and the "valid-client-cert option" if a client certificate has
2326 been verified.

2358PH/30 Exim was sometimes attempting to deliver messages that had suffered
2359 address errors (4xx response to RCPT) over the same connection as other
2360 messages routed to the same hosts. Such deliveries are always "forced",
2361 so retry times are not inspected. This resulted in far too many retries
2362 for the affected addresses. The effect occurred only when there were more
2363 hosts than the hosts_max_try setting in the smtp transport when it had
2364 the 4xx errors. Those hosts that it had tried were not added to the list
2365 of hosts for which the message was waiting, so if all were tried, there
2366 was no problem. Two fixes have been applied:
2367
2368 (i) If there are any address or message errors in an SMTP delivery, none
2369 of the hosts (tried or untried) are now added to the list of hosts
2370 for which the message is waiting, so the message should not be a
2371 candidate for sending over the same connection that was used for a
2372 successful delivery of some other message. This seems entirely
2373 reasonable: after all the message is NOT "waiting for some host".
2374 This is so "obvious" that I'm not sure why it wasn't done
2375 previously. Hope I haven't missed anything, but it can't do any
2376 harm, as the worst effect is to miss an optimization.
2377
2378 (ii) If, despite (i), such a delivery is accidentally attempted, the
2379 routing retry time is respected, so at least it doesn't keep
2380 hammering the server.

2395PH/35 The error "getsockname() failed: connection reset by peer" was being
2396 written to the panic log as well as the main log, but it isn't really
2397 panic-worthy as it just means the connection died rather early on. I have
2398 removed the panic log writing for the ECONNRESET error when getsockname()
2399 fails.

48c7f9e2
PH
2401PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2402 runs only) independently of the message's sender address. This meant
2403 that, if the 4xx error was in fact related to the sender, a different
2404 message to the same recipient with a different sender could confuse
2405 things. In particualar, this can happen when sending to a greylisting
2406 server, but other circumstances could also provoke similar problems.
2407 I have changed the default so that the retry time for these errors is now
2408 based a combination of the sender and recipient addresses. This change
2409 can be overridden by setting address_retry_include_sender=false in the
2410 smtp transport.

2771 autoreply, Exim could try to deliver to a non-existent relative file

2792 changes:
2793
2794 (a) Failures to set uid/gid, the current directory, or a process leader
2795 in a subprocess such as that created by queryprogram now generate
2796 suitable debugging ouput when -d is set.

2805PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2806 additional section of a DNS packet that returns MX or SRV records.
2807 Instead, it always explicitly searches for A/AAAA records. This avoids
2808 major problems that occur when a DNS server includes only records of one
2809 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2810 fixed another bug: if SRV records were looked up and the corresponding
2811 address records were *not* found in the additional section, the port
2812 values from the SRV records were lost.

PH
2822PH/19 When calculating a retry time, Exim used to measure the "time since
2823 failure" by looking at the "first failed" field in the retry record. Now
2824 it does not use this if it is later than than the arrival time of the
2825 message. Instead it uses the arrival time. This makes for better
2826 behaviour in cases where some deliveries succeed, thus re-setting the
2827 "first failed" field. An example is a quota failure for a huge message
2828 when small messages continue to be delivered. Without this change, the
2829 "time since failure" will always be short, possible causing more frequent
2830 delivery attempts for the huge message than are intended.

2927PH/42 The content-scanning code uses fopen() to create files in which to put
2928 message data. Previously it was not paying any attention to the mode of
2929 the files. Exim runs with umask(0) because the rest of the code creates
2930 files with open(), and sets the required mode explicitly. Thus, these
2931 files were ending up world-writeable. This was not a big issue, because,
2932 being within the spool directory, they were not world-accessible. I have
2933 created a function called modefopen, which takes an additional mode
2934 argument. It sets umask(777), creates the file, chmods it to the required
2935 mode, then resets the umask. All the relevant calls to fopen() in the
2936 content scanning code have been changed to use this function.

2973
2974 (i) Exim was not creating retry information for temporary errors given
2975 for individual recipients after the DATA command when the smtp transport
2976 was used in LMTP mode. This meant that they could be retried too
2977 frequently, and not timed out correctly.
2978
2979 (ii) Exim was setting the flag that allows error details to be returned
2980 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2981 recipients that were returned after the DATA command.
2982
2983PH/53 This is related to PH/52, but is more general: for any failing address,
2984 when detailed error information was permitted to be returned to the
2985 sender, but the error was temporary, then after the final timeout, only
2986 "retry timeout exceeded" was returned. Now it returns the full error as

3058 function verify_get_ident() calls ip_connect() to connect a socket, but
3059 if the "connect()" function timed out, ip_connect() used to close the
3060 socket. However, verify_get_ident() also closes the socket later, and in
3061 between Exim writes to the log, which may get opened at this point. When
3062 the socket was closed in ip_connect(), the log could get the same file
3063 descriptor number as the socket. This naturally causes chaos. The fix is
3064 not to close the socket in ip_connect(); the socket should be closed by
3065 the function that creates it. There was only one place in the code where
3066 this was missing, in the iplookup router, which I don't think anybody now
3067 uses, but I've fixed it anyway.

3126 IP address twice in Received: lines, even though the IP addresses were
3127 identical. For example:
3128
3129 Received: from [1.2.3.4] (helo=[1.2.3.4])
3130

3135PH/07 When both +timestamp and +memory debugging was on, the value given by
3136 $tod_xxx expansions could be wrong, because the tod_stamp() function was
3137 called by the debug printing, thereby overwriting the timestamp buffer.
3138 Debugging no longer uses the tod_stamp() function when +timestamp is set.

3159PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
3160 Electronic Mail") by including:
3161
3162 Auto-submitted: auto-generated
3163
3164 in the messages that it generates (bounce messages and others, such as
3165 warnings). In the case of bounce messages for non-SMTP mesages, there was
3166 also a typo: it was using "Auto_submitted" (underscore instead of
3167 hyphen). Since every message generated by Exim is necessarily in response
3168 to another message, thes have all been changed to:
3169
3170 Auto-Submitted: auto-replied
3171
3172 in accordance with these statements in the RFC:
3173
3174 The auto-replied keyword:
3175
3176 - SHOULD be used on messages sent in direct response to another
3177 message by an automatic process,
3178
3179 - MUST NOT be used on manually-generated messages,
3180
3181 - MAY be used on Delivery Status Notifications (DSNs) and Message
3182 Disposition Notifications (MDNs),
3183
3184 - MUST NOT be used on messages generated by automatic or periodic
3185 processes, except for messages which are automatic responses to
3186 other messages.

3207PH/17 A further patch from the Sieve maintainer: "Introduce the new Sieve
3208 extension "envelope-auth". The code is finished and in agreement with
3209 other implementations, but there is no documentation so far and in fact,
3210 nobody wrote the draft yet. This extension is currently #undef'ed, thus
3211 not changing the active code.
3212
3213 Print executed "if" and "elsif" statements when debugging is used. This
3214 helps a great deal to understand what a filter does.

3217 sorted out, when out of a sudden new issues came to my mind. Oops."

PH
3222PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
3223 canonical form (as documented). However, after a host name lookup from
3224 the IP address, check_host() was doing a simple string comparison with
3225 addresses acquired from the DNS when checking that the found name did
3226 have the original IP as one of its addresses. Since any found IPv6
3227 addresses are likely to be in abbreviated form, the comparison could
3228 fail. Luckily, there already exists a function for doing the comparison
3229 by converting both addresses to binary, so now that is used instead of
3230 the text comparison.
3231
96776534
PH
3232PH/20 There was another similar case to PH/19, when a complete host name was
3233 given in a host list; looking up its IP address could give an abbreviated
3234 form, whereas the current host's name might or might not be abbreviated.
3235 The same fix has been applied.
