9427e879 11JH/01 Bug 1922: Support IDNA2008. This has slightly different conversion rules
4c04137d 12 than -2003 did; needs libidn2 in addition to libidn.

19JH/03 Bug 2003: fix Proxy Protocol v2 handling: the address size field was
20 missing a wire-to-host endian conversion.

JH
22JH/04 Bug 2004: fix CHUNKING in non-PIPELINEING mode. Chunk data following
23 close after a BDAT command line could be taken as a following command,
24 giving a synch failure. Fix by only checking for synch immediately
25 before acknowledging the chunk.

27PP/02 GitHub PR 52: many spelling fixes, which include fixing parsing of
28 no_require_dnssec option and creation of _HAVE_TRANSPORT_APPEND_MAILDIR
29 macro. Patches provided by Josh Soref.

31JH/05 Bug 2017: Fix DKIM verification in -bh test mode. The data feed into
32 the dkim code may be unix-mode line endings rather than smtp wire-format
33 CRLF, so prepend a CR to any bare LF.

35JH/06 Rationalise the coding for callout smtp conversations and transport ones.
36 As a side-benfit, callouts can now use PIPELINING hence fewer round-trips.

42JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
43 supports it and a size is available (ie. the sending peer gave us one).
8d042305 44

JH
45JH/02 The obsolete acl condition "demime" is removed (finally, after ten
46 years of being deprecated). The replacements are the ACLs
47 acl_smtp_mime and acl_not_smtp_mime.
48
4b0fe319
JH
49JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
50 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
51 or even an in-clear connection were permitted. Now, if the host lookup
52 was dnssec and dane was requested then the host is only used if the
53 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
54 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
55 if one fails this test.
56 This means that a poorly-configured remote DNS will make it incommunicado;
57 but it protects against a DNS-interception attack on it.

59JH/04 Bug 1810: make continued-use of an open smtp transport connection
60 non-noisy when a race steals the message being considered.

f59aaaaa 63 self-signed certificate for inbound TLS connections.

68JH/07 Retire gnutls_require_mac et.al. These were nonfunctional since 4.80
69 and logged a warning sing 4.83; now they are a configuration file error.

76JH/10 Support ${sha256:} applied to a string (as well as the previous
77 certificate).
78

JH
79JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
80 a cutthrough deliver is pending, as we always want to make a connection.
81 This also avoids re-routing the message when later placing the cutthrough
82 connection after a verify cache hit.
83 Do not update it with the verify result either.
84
85JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
86 when routing results in more than one destination address.
87
ae8386f0
JH
88JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
89 signing (which inhibits the cutthrough capability). Previously only
90 the presence of an option was tested; now an expansion evaluating as
91 empty is permissible (obviously it should depend only on data available
92 when the cutthrough connection is made).
93

94JH/14 Fix logging of errors under PIPELINING. Previously the log line giving
95 the relevant preceding SMTP command did not note the pipelining mode.

100JH/16 DANE: treat a TLSA lookup response having all non-TLSA RRs, the same
101 as one having no matching records. Previously we deferred the message
102 that needed the lookup.

118JH/22 Fix continued use of a connection for further deliveries. If a port was
119 specified by a router, it must also match for the delivery to be
120 compatible.
121

JH
122JH/23 Bug 1874: fix continued use of a connection for further deliveries.
123 When one of the recipients of a message was unsuitable for the connection
124 (has no matching addresses), we lost track of needing to mark it
125 deferred. As a result mail would be lost.

f59aaaaa 129JH/25 Decoding ACL controls is now done using a binary search; the source code
2d009132
JH
130 takes up less space and should be simpler to maintain. Merge the ACL
131 condition decode tables also, with similar effect.

d1f9fb42
JH
133JH/26 Fix problem with one_time used on a redirect router which returned the
134 parent address unchanged. A retry would see the parent address marked as
135 delivered, so not attempt the (identical) child. As a result mail would
136 be lost.

138JH/27 Fix a possible security hole, wherein a process operating with the Exim
139 UID can gain a root shell. Credit to http://www.halfdog.net/ for
140 discovery and writeup. Ubuntu bug 1580454; no bug raised against Exim
141 itself :(

f59aaaaa 160 GnuTLS, when a session startup failed (eg because the client disconnected)
ad7fc6eb
JH
161 Exim did stdio operations after fclose. This was exposed by a recent
162 change which nulled out the file handle after the fclose.

164JH/32 Bug 1909: Fix OCSP proof verification for cases where the proof is
165 signed directly by the cert-signing cert, rather than an intermediate
166 OCSP-signing cert. This is the model used by LetsEncrypt.

JH
186JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
187 and 3.4.4 - once the server is enabled to respond to an OCSP request
188 it does even when not requested, resulting in a stapling non-aware
189 client dropping the TLS connection.

194TF/02 Improve the consistency of logging incoming and outgoing interfaces.
195 The I= interface field on outgoing lines is now after the H= remote
196 host field, same as incoming lines. There is a separate
197 outgoing_interface log selector which allows you to disable the
198 outgoing I= field.

200JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
201 If not running log_selector +smtp_connection the mainlog would be held
202 open indefinitely after a "too many connections" event, including to a
203 deleted file after a log rotate. Leave the per net connection logging
204 leaving it open for efficiency as that will be quickly detected by the
205 check on the next write.

207HS/01 Bug 1671: Fix post transport crash.
208 Processing the wait-<transport> messages could crash the delivery
209 process if the message IDs didn't exist for some reason. When
210 using 'split_spool_directory=yes' the construction of the spool
211 file name failed already, exposing the same netto behaviour.

217 to DSN fail messages (bounces): remote IP, remote greeting, remote response
218 to HELO, local diagnostic string.
219
805bb5c3
JH
220JH/05 Downgrade message for a TLS-certificate-based authentication fail from
221 log line to debug. Even when configured with a tls authenticator many
222 client connections are expected to not authenticate in this way, so
223 an authenticate fail is not an error.

4c04137d 228JH/06 Bug 1395: time-limit caching of DNS lookups, to the TTL value. This may
14b3c5bc

229 matter for fast-change records such as DNSBLs.
230
6f6dedcc
JH
231JH/07 Bug 1678: Always record an interface option value, if set, as part of a
232 retry record, even if constant. There may be multiple transports with
233 different interface settings and the retry behaviour needs to be kept
234 distinct.

JH
260JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
261 defaults to "*" (all hosts). The variable is now available when not built
4c04137d 262 with TLS, default unset, mainly to enable keeping the testsuite sane.
23f3dc67
JH
263 If a server certificate is not supplied (via tls_certificate) an error is
264 logged, and clients will find TLS connections fail on startup. Presumably
265 they will retry in-clear.
266 Packagers of Exim are strongly encouraged to create a server certificate
267 at installation time.

JB
272JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
273 in transport context, after the attempt, and per-recipient. The latter type
274 is per host attempted. The event data is the error message, and the errno
275 information encodes the lookup type (A vs. MX) used for the (first) host,
4c04137d 276 and the trailing two digits of the smtp 4xx response.

278GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
279 to write to mainlog (or rejectlog, paniclog) in the window between file
280 creation and permissions/ownership being changed. Particularly affects
281 installations where exicyclog is run as root, rather than exim user;
282 result is that the running daemon panics and dies.

322JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
323 support, by using OpenSSL or GnuTLS library ones. This means DKIM is

JH
338JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
339 incorrectly not doubled on cutthrough transmission, hence seen as a
340 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 341 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
342 via the normal store-and-forward channel. This could result in duplicates
343 received - but deduplicating mailstores were liable to retain only the
344 initial truncated version.

871TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
872
873 When a queue runner is handling a message, Exim first routes the
874 recipient addresses, during which it prunes them based on the retry
875 hints database. After that it attempts to deliver the message to
876 any remaining recipients. It then updates the hints database using
877 the retry rules.
878
879 So if a recipient address works intermittently, it can get repeatedly
880 deferred at routing time. The retry hints record remains fresh so the
881 address never reaches the final cutoff time.
882
883 This is a fairly common occurrence when a user is bumping up against
884 their storage quota. Exim had some logic in its local delivery code
885 to deal with this. However it did not apply to per-recipient defers
886 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
887
1ddeb334
TF
888 This change adds a proper retry rule check during routing so that the
889 final cutoff time is checked against the message's age. We only do
890 this check if there is an address retry record and there is not a
891 domain retry record; this implies that previous attempts to handle
892 the address had the retry_use_local_parts option turned on. We use
893 this as an approximation for the destination being like a local
894 delivery, as in LMTP.
67bd1ab3
TF
895
896 I suspect this new check makes the old local delivery cutoff check
897 redundant, but I have not verified this so I left the code in place.

906 the header to contain my full name, whereas it should have added
907 a Resent-Sender: header. It erroneously treats any prefix of the
908 username as equal to the username.

932 Server implementation by Todd Lyons, client by JH.

937 the body content is received and before the acl_smtp_data ACL.

1219TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1220 lock up or crash if it happened to be inside a call to libc when it
1221 got a SIGUSR1 from exiwhat.
1222
1223 The SIGUSR1 handler appends the current process status to the process
1224 log which is later printed by exiwhat. It used to use the general
1225 purpose logging code to do this, but several functions it calls are
1226 not safe for signals.
1227
1228 The new output code in the SIGUSR1 handler is specific to the process
1229 log, and simple enough that it's easy to inspect for signal safety.
1230 Removing some special cases also simplifies the general logging code.
1231 Removing the spurious timestamps from the process log simplifies
1232 exiwhat.
1233

TF
1234TF/04 Improved ratelimit ACL condition.
1235
1236 The /noupdate option has been deprecated in favour of /readonly which
1237 has clearer semantics. The /leaky, /strict, and /readonly update modes
1238 are mutually exclusive. The update mode is no longer included in the
1239 database key; it just determines when the database is updated. (This
4c04137d 1240 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1241
1242 Exim now checks that the per_* options are used with an update mode that
1243 makes sense for the current ACL. For example, when Exim is processing a
1244 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1245 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1246 must specify per_mail/readonly. If you omit the update mode it defaults to
1247 /leaky where that makes sense (as before) or /readonly where required.
1248
1249 The /noupdate option is now undocumented but still supported for
1250 backwards compatibility. It is equivalent to /readonly except that in
1251 ACLs where /readonly is required you may specify /leaky/noupdate or
1252 /strict/noupdate which are treated the same as /readonly.
1253
1254 A useful new feature is the /count= option. This is a generalization
1255 of the per_byte option, so that you can measure the throughput of other
1256 aggregate values. For example, the per_byte option is now equivalent
1257 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1258
1259 The per_rcpt option has been generalized using the /count= mechanism
1260 (though it's more complicated than the per_byte equivalence). When it is
1261 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1262 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1263 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1264 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1265 Note that using per_rcpt with a non-readonly update mode in more than
1266 one ACL will cause the recipients to be double-counted. (The per_mail
1267 and per_byte options don't have this problem.)
1268
1269 The handling of very low rates has changed slightly. If the computed rate
1270 is less than the event's count (usually one) then this event is the first
1271 after a long gap. In this case the rate is set to the same as this event's
1272 count, so that the first message of a spam run is counted properly.
1273
1274 The major new feature is a mechanism for counting the rate of unique
1275 events. The new per_addr option counts the number of different
1276 recipients that someone has sent messages to in the last time period. It
1277 behaves like per_rcpt if all the recipient addresses are different, but
1278 duplicate recipient addresses do not increase the measured rate. Like
1279 the /count= option this is a general mechanism, so the per_addr option
1280 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1281 example, measure the rate that a client uses different sender addresses
1282 with the options per_mail/unique=$sender_address. There are further
1283 details in the main documentation.

1853-----------------
1854
1855PH/01 Another patch from the Sieve maintainer.
1856
6a3bceb1
PH
1857PH/02 When an IPv6 address is converted to a string for single-key lookup
1858 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1859 dots are used instead of colons so that keys in lsearch files need not
1860 contain colons. This was done some time before quoting was made available
1861 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1862 (notated using the quote facility) so as to distinguish them from IPv4
1863 keys. This meant that lookups for IP addresses in host lists did not work
1864 for iplsearch lookups.
1865
1866 This has been fixed by arranging for IPv6 addresses to be expressed with
1867 colons if the lookup type is iplsearch. This is not incompatible, because
1868 previously such lookups could never work.
1869
4c04137d 1870 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
1871 ordinary lsearch keys. However, making the change in all cases is
1872 incompatible and would probably break a number of configurations.

MH
1877MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1878 conversion specification without a maximum field width, thereby enabling
1879 a rogue spamd server to cause a buffer overflow. While nobody in their
1880 right mind would setup Exim to query an untrusted spamd server, an
1881 attacker that gains access to a server running spamd could potentially
1882 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
1887MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1888 a directory entry by the name of the lookup key. Previously, if a
1889 symlink pointed to a non-existing file or a file in a directory that
1890 Exim lacked permissions to read, a lookup for a key matching that
1891 symlink would fail. Now it is enough that a matching directory entry
1892 exists, symlink or not. (Bugzilla 503.)

2075PH/29 SMTP synchronization checks are implemented when a command is read -
2076 there is a check that no more input is waiting when there shouldn't be

2078 some time before the response is written. In this time, more input might
2079 arrive, invalidly. So now there are extra checks after an ACL has run for
2080 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2081 pipelining has not been advertised.

PH
2155 the response to the final '.' that terminates a message, but only in the
2156 case where the client has not sent further data following the '.'
2157 (unfortunately, this is allowed). However, in many cases there won't be
2158 any further data because there won't be any more messages to send. A call
2159 to select() can be used: if it shows that the input is "ready", there is
2160 either input waiting, or the socket has been closed. An attempt to read
2161 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2162 would have sent an OK response which the client would never have see.

2173PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2174 fixed by 4.65/MH/01 (is this a record?) are fixed:
2175
2176 (i) An empty string was always treated as zero by the numeric comparison
2177 operators. This behaviour has been restored.
2178
2179 (ii) It is documented that the numeric comparison operators always treat
2180 their arguments as decimal numbers. This was broken in that numbers
2181 starting with 0 were being interpreted as octal.
2182
2183 While fixing these problems I realized that there was another issue that
2184 hadn't been noticed. Values of message_size_limit (both the global option
2185 and the transport option) were treated as octal if they started with 0.
2186 The documentation was vague. These values are now always treated as
2187 decimal, and I will make that clear in the documentation.

PH
2231PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2232 callout verification, Exim cached a "reject" for the entire domain. This
2233 is correct for most verifications, but it is not correct for a recipient
2234 verification with use_sender or use_postmaster set, because in that case
2235 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2236 case of MAIL FROM:<> rejection from other early rejections (e.g.
2237 rejection of HELO). When verifying a recipient using a non-null MAIL
2238 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2239 Whatever the result of the callout, the value of the domain cache is
2240 left unchanged (for any other kind of callout, getting as far as trying
2241 RCPT means that the domain itself is ok).

2277 probably the interface on which it is arriving) and not to the outgoing
2278 callout (which could be using a different interface). This has been
2279 changed to use the value of the helo_data option from the smtp transport
2280 instead - this is what is used when a message is actually being sent. If
2281 there is no remote transport (possible with a router that sets up host
2282 addresses), $smtp_active_hostname is used.

14aa5a05
PH
2286 (a) The code assumed that strncpy() returns a negative number on buffer
2287 overflow, which isn't the case. Replaced with Exim's string_format()
2288 function.
2289 (b) There were several signed/unsigned issues. I just did the minimum
2290 hacking in of casts. There is scope for a larger refactoring.
2291 (c) The code used strcasecmp() which is not a standard C function.
2292 Replaced with Exim's strcmpic() function.
2293 (d) The code set only $1; it now sets $auth1 as well.
2294 (e) A simple test gave the error "authentication client didn't specify
2295 service in request". It would seem that Dovecot has changed its
2296 interface. Fortunately there's a specification; I followed it and
2297 changed what the client sends and it appears to be working now.

2305 successful redirection if more than one address is generated. However,
2306 with -v the child addresses are also verified. Exim was outputting "A
2307 failed to verify" and then showing the successful verification for C,

2315PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2316 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2317 they consult the DNS. I had assumed they would set it the way they
2318 wanted; and indeed my experiments on Linux seem to show that in some
2319 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2320 To be on the safe side, however, I have now made the interface to
2321 host_find_byname() similar to host_find_bydns(), with an argument
2322 containing the DNS resolver options. The host_find_byname() function now
2323 sets these options at its start, just as host_find_bydns() does. The smtp
2324 transport options dns_qualify_single and dns_search_parents are passed to
2325 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2326 of host_find_byname() use the default settings of RES_DEFNAMES
2327 (qualify_single) but not RES_DNSRCH (search_parents).

PH
2329PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2330 spool_read_header() do less string testing, by means of a preliminary
2331 switch on the second character of optional "-foo" lines. (This is
2332 overdue, caused by the large number of possibilities that now exist.
2333 Originally there were few.) While I was there, I also converted the
2334 str(n)cmp tests so they don't re-test the leading "-" and the first
2335 character, in the hope this might squeeze out yet more improvement.

2337PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2338 flag allowing group syntax was set by the header_syntax check but not
2339 turned off, possible causing trouble later; (2) The flag was not being
2340 set at all for the header_verify test, causing "group"-style headers to
2341 be rejected. I have now set it in this case, and also caused header_
2342 verify to ignore an empty address taken from a group. While doing this, I
2343 came across some other cases where the code for allowing group syntax
2344 while scanning a header line wasn't quite right (mostly, not resetting
2345 the flag correctly in the right place). These bugs could have caused
2346 trouble for malformed header lines. I hope it is now all correct.

2348PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2349 with the "reply" argument non-NULL. The code, however (which originally
2350 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2351 but it didn't always do it. This confused somebody who was copying the
2352 code for some other use. I have removed all the tests.

PH
2354PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2355 feature that was used to support insecure browsers during the U.S. crypto
2356 embargo. It requires special client support, and Exim is probably the
2357 only MTA that supported it -- and would never use it because real RSA is
2358 always available. This code has been removed, because it had the bad
2359 effect of slowing Exim down by computing (never used) parameters for the
2360 RSA_EXPORT functionality.

PH
2362PH/21 On the advice of Timo Sirainen, added a check to the dovecot

2365 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2366 if the connection is using TLS or if the remote IP is the same as the
2367 local IP, and the "valid-client-cert option" if a client certificate has
2368 been verified.

2399
2400PH/30 Exim was sometimes attempting to deliver messages that had suffered
2401 address errors (4xx response to RCPT) over the same connection as other
2402 messages routed to the same hosts. Such deliveries are always "forced",
2403 so retry times are not inspected. This resulted in far too many retries
2404 for the affected addresses. The effect occurred only when there were more
2405 hosts than the hosts_max_try setting in the smtp transport when it had
2406 the 4xx errors. Those hosts that it had tried were not added to the list
2407 of hosts for which the message was waiting, so if all were tried, there
2408 was no problem. Two fixes have been applied:
2409
2410 (i) If there are any address or message errors in an SMTP delivery, none
2411 of the hosts (tried or untried) are now added to the list of hosts
2412 for which the message is waiting, so the message should not be a
2413 candidate for sending over the same connection that was used for a
2414 successful delivery of some other message. This seems entirely
2415 reasonable: after all the message is NOT "waiting for some host".
2416 This is so "obvious" that I'm not sure why it wasn't done
2417 previously. Hope I haven't missed anything, but it can't do any
2418 harm, as the worst effect is to miss an optimization.
2419
2420 (ii) If, despite (i), such a delivery is accidentally attempted, the
2421 routing retry time is respected, so at least it doesn't keep
2422 hammering the server.

2438 written to the panic log as well as the main log, but it isn't really

2440 removed the panic log writing for the ECONNRESET error when getsockname()
2441 fails.
2442
48c7f9e2
PH
2443PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2444 runs only) independently of the message's sender address. This meant
2445 that, if the 4xx error was in fact related to the sender, a different
2446 message to the same recipient with a different sender could confuse
4c04137d 2447 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2448 server, but other circumstances could also provoke similar problems.
2449 I have changed the default so that the retry time for these errors is now
2450 based a combination of the sender and recipient addresses. This change
2451 can be overridden by setting address_retry_include_sender=false in the
2452 smtp transport.

2720PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
2721 "Deny" causes Exim to reject the incoming connection with a 554 error.
2722 Unfortunately, if there is a major crisis, such as a disk failure,
2723 tcp-wrappers gives "deny", whereas what one would like would be some
2724 kind of temporary error. A kludge has been added to help with this.
2725 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2726 554 error is used if errno is still zero or contains ENOENT (which occurs
2727 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2728 451 error is used.

2753 used only to exclude .Trash (or whatever) when the size of the mailbox
2754 was calculated. There was no check that a delivery was happening into an

2762-----------------
2763
2764PH/01 The code for finding all the local interface addresses on a FreeBSD
2765 system running IPv6 was broken. This may well have applied to all BSD
2766 systems, as well as to others that have similar system calls. The broken
2767 code found IPv4 interfaces correctly, but gave incorrect values for the
2768 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2769 that it would not match correctly against @[] and not recognize the IPv6
2770 addresses as local.

2812 generate an autoreply, and therefore failed to obtain an address for the
2813 autoreply, Exim could try to deliver to a non-existent relative file
2814 name, causing unrelated and misleading errors. What now happens is that
2815 it logs this as a hard delivery error, but does not attempt to create a

2847PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2848 additional section of a DNS packet that returns MX or SRV records.
2849 Instead, it always explicitly searches for A/AAAA records. This avoids
2850 major problems that occur when a DNS server includes only records of one
2851 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2852 fixed another bug: if SRV records were looked up and the corresponding
2853 address records were *not* found in the additional section, the port
2854 values from the SRV records were lost.

2856PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

2863
727071f8
PH
2864PH/19 When calculating a retry time, Exim used to measure the "time since
2865 failure" by looking at the "first failed" field in the retry record. Now
2866 it does not use this if it is later than than the arrival time of the
2867 message. Instead it uses the arrival time. This makes for better
2868 behaviour in cases where some deliveries succeed, thus re-setting the
2869 "first failed" field. An example is a quota failure for a huge message
2870 when small messages continue to be delivered. Without this change, the
2871 "time since failure" will always be short, possible causing more frequent
2872 delivery attempts for the huge message than are intended.

PH
2969PH/42 The content-scanning code uses fopen() to create files in which to put
2970 message data. Previously it was not paying any attention to the mode of
2971 the files. Exim runs with umask(0) because the rest of the code creates
2972 files with open(), and sets the required mode explicitly. Thus, these
2973 files were ending up world-writeable. This was not a big issue, because,
2974 being within the spool directory, they were not world-accessible. I have
2975 created a function called modefopen, which takes an additional mode
2976 argument. It sets umask(777), creates the file, chmods it to the required
2977 mode, then resets the umask. All the relevant calls to fopen() in the

3015
3016 (i) Exim was not creating retry information for temporary errors given

3018 was used in LMTP mode. This meant that they could be retried too
3019 frequently, and not timed out correctly.
3020
3021 (ii) Exim was setting the flag that allows error details to be returned
3022 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3023 recipients that were returned after the DATA command.
3024
3025PH/53 This is related to PH/52, but is more general: for any failing address,
3026 when detailed error information was permitted to be returned to the

3085PH/68 The bounce_return_message and bounce_return_body options were not being
3086 honoured for bounces generated during the reception of non-SMTP messages.
3087 In particular, this applied to messages rejected by the ACL. This bug has
3088 been fixed. However, if bounce_return_message is true and bounce_return_
3089 body is false, the headers that are returned for a non-SMTP message
3090 include only those that have been read before the error was detected.
3091 (In the case of an ACL rejection, they have all been read.)

3099PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3100 function verify_get_ident() calls ip_connect() to connect a socket, but
3101 if the "connect()" function timed out, ip_connect() used to close the
3102 socket. However, verify_get_ident() also closes the socket later, and in
3103 between Exim writes to the log, which may get opened at this point. When
3104 the socket was closed in ip_connect(), the log could get the same file
3105 descriptor number as the socket. This naturally causes chaos. The fix is
3106 not to close the socket in ip_connect(); the socket should be closed by
3107 the function that creates it. There was only one place in the code where
3108 this was missing, in the iplookup router, which I don't think anybody now
3109 uses, but I've fixed it anyway.

3128PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3129
3130 (1) Generate an error if the third argument for the ${prvs expansion is
3131 not a single digit.
3132
3133 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3134 string.
3135
3136 (3) Reset the variables that are obtained from the first argument of
3137 ${prvscheck and used in the second argument before leaving the code,
3138 because their memory is reclaimed, so using them afterwards may do
3139 silly things.
3140
3141 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3142 one (it's much easier than Tom thought :-).
3143
3144 (5) Because of (4), we can now allow for the use of $prvscheck_result
3145 inside the third argument.

3156
3157 => >A.N.Other <ano@some.domain> <original@ddress> ...
3158
3159 This has been changed so that it extracts the operative address. There
3160 may be more than one such address. If so, they are comma-separated, like
3161 this:

3165PH/06 When a client host used a correct literal IP address in a HELO or EHLO
3166 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3167 not being looked up in the rDNS to get a host name, Exim was showing the
3168 IP address twice in Received: lines, even though the IP addresses were
3169 identical. For example:
3170
3171 Received: from [1.2.3.4] (helo=[1.2.3.4])
3172
3173 However, if the real host name was known, it was omitting the HELO data
3174 if it matched the actual IP address. This has been tidied up so that it
3175 doesn't show the same IP address twice.

3201PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

3204 Auto-submitted: auto-generated

PH
3208 also a typo: it was using "Auto_submitted" (underscore instead of

3210 to another message, thes have all been changed to:
3211
3212 Auto-Submitted: auto-replied
3213
3214 in accordance with these statements in the RFC:
3215
3216 The auto-replied keyword:
3217
3218 - SHOULD be used on messages sent in direct response to another
3219 message by an automatic process,
3220
3221 - MUST NOT be used on manually-generated messages,
3222
3223 - MAY be used on Delivery Status Notifications (DSNs) and Message
3224 Disposition Notifications (MDNs),

3226 - MUST NOT be used on messages generated by automatic or periodic
3227 processes, except for messages which are automatic responses to
3228 other messages.

3252 nobody wrote the draft yet. This extension is currently #undef'ed, thus
3253 not changing the active code.

3264PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
3265 canonical form (as documented). However, after a host name lookup from
3266 the IP address, check_host() was doing a simple string comparison with
3267 addresses acquired from the DNS when checking that the found name did
3268 have the original IP as one of its addresses. Since any found IPv6
3269 addresses are likely to be in abbreviated form, the comparison could
3270 fail. Luckily, there already exists a function for doing the comparison
3271 by converting both addresses to binary, so now that is used instead of
3272 the text comparison.

PH
3274PH/20 There was another similar case to PH/19, when a complete host name was
