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.

JH
31JH/05 Have the EHLO response advertise VRFY, if there is a vrfy ACL defined.
32 Previously we did not; the RFC seems ambiguous and VRFY is not listed
33 by IANA as a service extension. However, John Klensin suggests that we
34 should.
35
36JH/06 Bug 2017: Fix DKIM verification in -bh test mode. The data feed into
b895f4b2
JH
37 the dkim code may be unix-mode line endings rather than smtp wire-format
38 CRLF, so prepend a CR to any bare LF.
fd047340 39
bd8fbe36 40JH/07 Rationalise the coding for callout smtp conversations and transport ones.
902fbd69
JH
41 As a side-benfit, callouts can now use PIPELINING hence fewer round-trips.
42
bd8fbe36
JH
43JH/08 Bug 2016: Fix DKIM verification vs. CHUNKING. Any BDAT commands after
44 the first were themselves being wrongly included in the feed into dkim
45 processing; with most chunk sizes in use this resulted in an incorrect
46 body hash calculated value.

52JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
53 supports it and a size is available (ie. the sending peer gave us one).
8d042305 54
03d5892b
JH
55JH/02 The obsolete acl condition "demime" is removed (finally, after ten
56 years of being deprecated). The replacements are the ACLs
57 acl_smtp_mime and acl_not_smtp_mime.
58
4b0fe319
JH
59JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
60 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
61 or even an in-clear connection were permitted. Now, if the host lookup
62 was dnssec and dane was requested then the host is only used if the
63 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
64 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
65 if one fails this test.
66 This means that a poorly-configured remote DNS will make it incommunicado;
67 but it protects against a DNS-interception attack on it.

69JH/04 Bug 1810: make continued-use of an open smtp transport connection
70 non-noisy when a race steals the message being considered.

f59aaaaa 73 self-signed certificate for inbound TLS connections.

78JH/07 Retire gnutls_require_mac et.al. These were nonfunctional since 4.80
79 and logged a warning sing 4.83; now they are a configuration file error.

82 (lacking @domain). Apply the same qualification processing as RCPT.

86JH/10 Support ${sha256:} applied to a string (as well as the previous
87 certificate).
88
98c82a3d
JH
89JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
90 a cutthrough deliver is pending, as we always want to make a connection.
91 This also avoids re-routing the message when later placing the cutthrough
92 connection after a verify cache hit.
93 Do not update it with the verify result either.
94
95JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
96 when routing results in more than one destination address.
97
ae8386f0
JH
98JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
99 signing (which inhibits the cutthrough capability). Previously only
100 the presence of an option was tested; now an expansion evaluating as
101 empty is permissible (obviously it should depend only on data available
102 when the cutthrough connection is made).
103
0d9fa8c0
JH
104JH/14 Fix logging of errors under PIPELINING. Previously the log line giving
105 the relevant preceding SMTP command did not note the pipelining mode.

107JH/15 Fix counting of empty lines in $body_linecount and $message_linecount.
108 Previously they were not counted.

110JH/16 DANE: treat a TLSA lookup response having all non-TLSA RRs, the same
111 as one having no matching records. Previously we deferred the message
112 that needed the lookup.

128JH/22 Fix continued use of a connection for further deliveries. If a port was
129 specified by a router, it must also match for the delivery to be
130 compatible.
131
e3b1f624
JH
132JH/23 Bug 1874: fix continued use of a connection for further deliveries.
133 When one of the recipients of a message was unsuitable for the connection
134 (has no matching addresses), we lost track of needing to mark it
135 deferred. As a result mail would be lost.

JH
137JH/24 Bug 1832: Log EHLO response on getting conn-close response for HELO.
138
f59aaaaa 139JH/25 Decoding ACL controls is now done using a binary search; the source code
2d009132
JH
140 takes up less space and should be simpler to maintain. Merge the ACL
141 condition decode tables also, with similar effect.
d7bed771 142
d1f9fb42
JH
143JH/26 Fix problem with one_time used on a redirect router which returned the
144 parent address unchanged. A retry would see the parent address marked as
145 delivered, so not attempt the (identical) child. As a result mail would
146 be lost.

148JH/27 Fix a possible security hole, wherein a process operating with the Exim
149 UID can gain a root shell. Credit to http://www.halfdog.net/ for
150 discovery and writeup. Ubuntu bug 1580454; no bug raised against Exim
151 itself :(

f59aaaaa 170 GnuTLS, when a session startup failed (eg because the client disconnected)
ad7fc6eb
JH
171 Exim did stdio operations after fclose. This was exposed by a recent
172 change which nulled out the file handle after the fclose.

174JH/32 Bug 1909: Fix OCSP proof verification for cases where the proof is
175 signed directly by the cert-signing cert, rather than an intermediate
176 OCSP-signing cert. This is the model used by LetsEncrypt.

196JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
197 and 3.4.4 - once the server is enabled to respond to an OCSP request
198 it does even when not requested, resulting in a stapling non-aware
199 client dropping the TLS connection.

204TF/02 Improve the consistency of logging incoming and outgoing interfaces.
205 The I= interface field on outgoing lines is now after the H= remote
206 host field, same as incoming lines. There is a separate
207 outgoing_interface log selector which allows you to disable the
208 outgoing I= field.

JH
210JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
211 If not running log_selector +smtp_connection the mainlog would be held
212 open indefinitely after a "too many connections" event, including to a
213 deleted file after a log rotate. Leave the per net connection logging
214 leaving it open for efficiency as that will be quickly detected by the
215 check on the next write.

217HS/01 Bug 1671: Fix post transport crash.
218 Processing the wait-<transport> messages could crash the delivery
219 process if the message IDs didn't exist for some reason. When
220 using 'split_spool_directory=yes' the construction of the spool
221 file name failed already, exposing the same netto behaviour.

227 to DSN fail messages (bounces): remote IP, remote greeting, remote response
228 to HELO, local diagnostic string.
229
805bb5c3
JH
230JH/05 Downgrade message for a TLS-certificate-based authentication fail from
231 log line to debug. Even when configured with a tls authenticator many
232 client connections are expected to not authenticate in this way, so
233 an authenticate fail is not an error.

239 matter for fast-change records such as DNSBLs.
240
6f6dedcc
JH
241JH/07 Bug 1678: Always record an interface option value, if set, as part of a

243 different interface settings and the retry behaviour needs to be kept
244 distinct.

270JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
271 defaults to "*" (all hosts). The variable is now available when not built
4c04137d 272 with TLS, default unset, mainly to enable keeping the testsuite sane.
23f3dc67
JH
273 If a server certificate is not supplied (via tls_certificate) an error is
274 logged, and clients will find TLS connections fail on startup. Presumably
275 they will retry in-clear.
276 Packagers of Exim are strongly encouraged to create a server certificate
277 at installation time.

282JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
283 in transport context, after the attempt, and per-recipient. The latter type
284 is per host attempted. The event data is the error message, and the errno
285 information encodes the lookup type (A vs. MX) used for the (first) host,
4c04137d 286 and the trailing two digits of the smtp 4xx response.

288GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
289 to write to mainlog (or rejectlog, paniclog) in the window between file
290 creation and permissions/ownership being changed. Particularly affects
291 installations where exicyclog is run as root, rather than exim user;
292 result is that the running daemon panics and dies.

332JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
333 support, by using OpenSSL or GnuTLS library ones. This means DKIM is

JH
348JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
349 incorrectly not doubled on cutthrough transmission, hence seen as a
350 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 351 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
352 via the normal store-and-forward channel. This could result in duplicates
353 received - but deduplicating mailstores were liable to retain only the
354 initial truncated version.

881TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
882
883 When a queue runner is handling a message, Exim first routes the
884 recipient addresses, during which it prunes them based on the retry
885 hints database. After that it attempts to deliver the message to
886 any remaining recipients. It then updates the hints database using
887 the retry rules.
888
889 So if a recipient address works intermittently, it can get repeatedly
890 deferred at routing time. The retry hints record remains fresh so the
891 address never reaches the final cutoff time.
892
893 This is a fairly common occurrence when a user is bumping up against
894 their storage quota. Exim had some logic in its local delivery code
895 to deal with this. However it did not apply to per-recipient defers
896 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
897
1ddeb334
TF
898 This change adds a proper retry rule check during routing so that the
899 final cutoff time is checked against the message's age. We only do
900 this check if there is an address retry record and there is not a
901 domain retry record; this implies that previous attempts to handle
902 the address had the retry_use_local_parts option turned on. We use
903 this as an approximation for the destination being like a local
904 delivery, as in LMTP.
67bd1ab3
TF
905
906 I suspect this new check makes the old local delivery cutoff check
907 redundant, but I have not verified this so I left the code in place.

911 Test 0254 submits a message to Exim with the header
912
913 Resent-From: f
914
915 When I ran the test suite under the user fanf2, Exim expanded
916 the header to contain my full name, whereas it should have added
917 a Resent-Sender: header. It erroneously treats any prefix of the
918 username as equal to the username.
919
920 This change corrects that bug.

941JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
942 Server implementation by Todd Lyons, client by JH.
943 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
944 config variable "prdr_enable" controls whether the server
945 advertises the facility. If the client requests PRDR a new
946 acl_data_smtp_prdr ACL is called once for each recipient, after
947 the body content is received and before the acl_smtp_data ACL.
4c04137d 948 The client is controlled by both of: a hosts_try_prdr option
fd98a5c6
JH
949 on the smtp transport, and the server advertisement.
950 Default client logging of deliveries and rejections involving

1229TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1230 lock up or crash if it happened to be inside a call to libc when it
1231 got a SIGUSR1 from exiwhat.
1232
1233 The SIGUSR1 handler appends the current process status to the process
1234 log which is later printed by exiwhat. It used to use the general
1235 purpose logging code to do this, but several functions it calls are
1236 not safe for signals.
1237
1238 The new output code in the SIGUSR1 handler is specific to the process
1239 log, and simple enough that it's easy to inspect for signal safety.
1240 Removing some special cases also simplifies the general logging code.
1241 Removing the spurious timestamps from the process log simplifies
1242 exiwhat.

TF
1244TF/04 Improved ratelimit ACL condition.
1245
1246 The /noupdate option has been deprecated in favour of /readonly which
1247 has clearer semantics. The /leaky, /strict, and /readonly update modes
1248 are mutually exclusive. The update mode is no longer included in the
1249 database key; it just determines when the database is updated. (This
4c04137d 1250 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1251
1252 Exim now checks that the per_* options are used with an update mode that
1253 makes sense for the current ACL. For example, when Exim is processing a
1254 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1255 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1256 must specify per_mail/readonly. If you omit the update mode it defaults to
1257 /leaky where that makes sense (as before) or /readonly where required.
1258
1259 The /noupdate option is now undocumented but still supported for
1260 backwards compatibility. It is equivalent to /readonly except that in
1261 ACLs where /readonly is required you may specify /leaky/noupdate or
1262 /strict/noupdate which are treated the same as /readonly.
1263
1264 A useful new feature is the /count= option. This is a generalization
1265 of the per_byte option, so that you can measure the throughput of other
1266 aggregate values. For example, the per_byte option is now equivalent
1267 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1268
1269 The per_rcpt option has been generalized using the /count= mechanism
1270 (though it's more complicated than the per_byte equivalence). When it is
1271 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1272 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1273 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1274 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1275 Note that using per_rcpt with a non-readonly update mode in more than
1276 one ACL will cause the recipients to be double-counted. (The per_mail
1277 and per_byte options don't have this problem.)
1278
1279 The handling of very low rates has changed slightly. If the computed rate
1280 is less than the event's count (usually one) then this event is the first
1281 after a long gap. In this case the rate is set to the same as this event's
1282 count, so that the first message of a spam run is counted properly.
1283
1284 The major new feature is a mechanism for counting the rate of unique
1285 events. The new per_addr option counts the number of different
1286 recipients that someone has sent messages to in the last time period. It
1287 behaves like per_rcpt if all the recipient addresses are different, but
1288 duplicate recipient addresses do not increase the measured rate. Like
1289 the /count= option this is a general mechanism, so the per_addr option
1290 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1291 example, measure the rate that a client uses different sender addresses
1292 with the options per_mail/unique=$sender_address. There are further
1293 details in the main documentation.

1862Exim version 4.68
1863-----------------
1864
1865PH/01 Another patch from the Sieve maintainer.
1866
6a3bceb1
PH
1867PH/02 When an IPv6 address is converted to a string for single-key lookup
1868 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1869 dots are used instead of colons so that keys in lsearch files need not
1870 contain colons. This was done some time before quoting was made available
1871 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1872 (notated using the quote facility) so as to distinguish them from IPv4
1873 keys. This meant that lookups for IP addresses in host lists did not work
1874 for iplsearch lookups.
1875
1876 This has been fixed by arranging for IPv6 addresses to be expressed with
1877 colons if the lookup type is iplsearch. This is not incompatible, because
1878 previously such lookups could never work.
1879
4c04137d 1880 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
1881 ordinary lsearch keys. However, making the change in all cases is
1882 incompatible and would probably break a number of configurations.

MH
1887MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1888 conversion specification without a maximum field width, thereby enabling
1889 a rogue spamd server to cause a buffer overflow. While nobody in their
1890 right mind would setup Exim to query an untrusted spamd server, an
1891 attacker that gains access to a server running spamd could potentially
1892 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
1897MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1898 a directory entry by the name of the lookup key. Previously, if a
1899 symlink pointed to a non-existing file or a file in a directory that
1900 Exim lacked permissions to read, a lookup for a key matching that
1901 symlink would fail. Now it is enough that a matching directory entry
1902 exists, symlink or not. (Bugzilla 503.)

2085PH/29 SMTP synchronization checks are implemented when a command is read -
2086 there is a check that no more input is waiting when there shouldn't be

2088 some time before the response is written. In this time, more input might
2089 arrive, invalidly. So now there are extra checks after an ACL has run for
2090 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2091 pipelining has not been advertised.

2147 with PIPELINING or a stupid MUA), the error message that was given to the

PH
2165 the response to the final '.' that terminates a message, but only in the
2166 case where the client has not sent further data following the '.'
2167 (unfortunately, this is allowed). However, in many cases there won't be
2168 any further data because there won't be any more messages to send. A call
2169 to select() can be used: if it shows that the input is "ready", there is
2170 either input waiting, or the socket has been closed. An attempt to read
2171 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2172 would have sent an OK response which the client would never have see.

2183PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2184 fixed by 4.65/MH/01 (is this a record?) are fixed:
2185
2186 (i) An empty string was always treated as zero by the numeric comparison
2187 operators. This behaviour has been restored.
2188
2189 (ii) It is documented that the numeric comparison operators always treat
2190 their arguments as decimal numbers. This was broken in that numbers
2191 starting with 0 were being interpreted as octal.
2192
2193 While fixing these problems I realized that there was another issue that
2194 hadn't been noticed. Values of message_size_limit (both the global option
2195 and the transport option) were treated as octal if they started with 0.
2196 The documentation was vague. These values are now always treated as
2197 decimal, and I will make that clear in the documentation.

2b1c6e3a
PH
2241PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2242 callout verification, Exim cached a "reject" for the entire domain. This
2243 is correct for most verifications, but it is not correct for a recipient
2244 verification with use_sender or use_postmaster set, because in that case
2245 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2246 case of MAIL FROM:<> rejection from other early rejections (e.g.
2247 rejection of HELO). When verifying a recipient using a non-null MAIL
2248 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2249 Whatever the result of the callout, the value of the domain cache is
2250 left unchanged (for any other kind of callout, getting as far as trying
2251 RCPT means that the domain itself is ok).

2287 probably the interface on which it is arriving) and not to the outgoing
2288 callout (which could be using a different interface). This has been
2289 changed to use the value of the helo_data option from the smtp transport
2290 instead - this is what is used when a message is actually being sent. If
2291 there is no remote transport (possible with a router that sets up host
2292 addresses), $smtp_active_hostname is used.

14aa5a05
PH
2296 (a) The code assumed that strncpy() returns a negative number on buffer
2297 overflow, which isn't the case. Replaced with Exim's string_format()
2298 function.
2299 (b) There were several signed/unsigned issues. I just did the minimum
2300 hacking in of casts. There is scope for a larger refactoring.
2301 (c) The code used strcasecmp() which is not a standard C function.
2302 Replaced with Exim's strcmpic() function.
2303 (d) The code set only $1; it now sets $auth1 as well.
2304 (e) A simple test gave the error "authentication client didn't specify
2305 service in request". It would seem that Dovecot has changed its
2306 interface. Fortunately there's a specification; I followed it and
2307 changed what the client sends and it appears to be working now.

2312PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2313 address A is aliased to B and C, where B exists and C does not. Without
2314 -v the output is "A verified" because verification stops after a
2315 successful redirection if more than one address is generated. However,
2316 with -v the child addresses are also verified. Exim was outputting "A
2317 failed to verify" and then showing the successful verification for C,
2318 with its parentage. It now outputs "B failed to verify", showing B's
2319 parentage before showing the successful verification of C.

PH
2325PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2326 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2327 they consult the DNS. I had assumed they would set it the way they
2328 wanted; and indeed my experiments on Linux seem to show that in some
2329 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2330 To be on the safe side, however, I have now made the interface to
2331 host_find_byname() similar to host_find_bydns(), with an argument
2332 containing the DNS resolver options. The host_find_byname() function now
2333 sets these options at its start, just as host_find_bydns() does. The smtp
2334 transport options dns_qualify_single and dns_search_parents are passed to
2335 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2336 of host_find_byname() use the default settings of RES_DEFNAMES
2337 (qualify_single) but not RES_DNSRCH (search_parents).

2339PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2340 spool_read_header() do less string testing, by means of a preliminary
2341 switch on the second character of optional "-foo" lines. (This is
2342 overdue, caused by the large number of possibilities that now exist.
2343 Originally there were few.) While I was there, I also converted the
2344 str(n)cmp tests so they don't re-test the leading "-" and the first
2345 character, in the hope this might squeeze out yet more improvement.

2347PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2348 flag allowing group syntax was set by the header_syntax check but not
2349 turned off, possible causing trouble later; (2) The flag was not being
2350 set at all for the header_verify test, causing "group"-style headers to
2351 be rejected. I have now set it in this case, and also caused header_
2352 verify to ignore an empty address taken from a group. While doing this, I
2353 came across some other cases where the code for allowing group syntax
2354 while scanning a header line wasn't quite right (mostly, not resetting
2355 the flag correctly in the right place). These bugs could have caused
2356 trouble for malformed header lines. I hope it is now all correct.

2358PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

2360 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2361 but it didn't always do it. This confused somebody who was copying the
2362 code for some other use. I have removed all the tests.

PH
2364PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2365 feature that was used to support insecure browsers during the U.S. crypto
2366 embargo. It requires special client support, and Exim is probably the
2367 only MTA that supported it -- and would never use it because real RSA is
2368 always available. This code has been removed, because it had the bad
2369 effect of slowing Exim down by computing (never used) parameters for the
2370 RSA_EXPORT functionality.

2375 to be base64-encoded). Also added, on Timo's advice, the "secured" option

2377 local IP, and the "valid-client-cert option" if a client certificate has
2378 been verified.

2409
2410PH/30 Exim was sometimes attempting to deliver messages that had suffered
2411 address errors (4xx response to RCPT) over the same connection as other
2412 messages routed to the same hosts. Such deliveries are always "forced",
2413 so retry times are not inspected. This resulted in far too many retries
2414 for the affected addresses. The effect occurred only when there were more
2415 hosts than the hosts_max_try setting in the smtp transport when it had
2416 the 4xx errors. Those hosts that it had tried were not added to the list
2417 of hosts for which the message was waiting, so if all were tried, there
2418 was no problem. Two fixes have been applied:
2419
2420 (i) If there are any address or message errors in an SMTP delivery, none
2421 of the hosts (tried or untried) are now added to the list of hosts
2422 for which the message is waiting, so the message should not be a
2423 candidate for sending over the same connection that was used for a
2424 successful delivery of some other message. This seems entirely
2425 reasonable: after all the message is NOT "waiting for some host".
2426 This is so "obvious" that I'm not sure why it wasn't done
2427 previously. Hope I haven't missed anything, but it can't do any
2428 harm, as the worst effect is to miss an optimization.
2429
2430 (ii) If, despite (i), such a delivery is accidentally attempted, the
2431 routing retry time is respected, so at least it doesn't keep
2432 hammering the server.

2448 written to the panic log as well as the main log, but it isn't really

2450 removed the panic log writing for the ECONNRESET error when getsockname()
2451 fails.

48c7f9e2
PH
2453PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2454 runs only) independently of the message's sender address. This meant
2455 that, if the 4xx error was in fact related to the sender, a different
2456 message to the same recipient with a different sender could confuse
4c04137d 2457 things. In particular, this can happen when sending to a greylisting
48c7f9e2

2458 server, but other circumstances could also provoke similar problems.
2459 I have changed the default so that the retry time for these errors is now
2460 based a combination of the sender and recipient addresses. This change
2461 can be overridden by setting address_retry_include_sender=false in the
2462 smtp transport.

2730PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
2731 "Deny" causes Exim to reject the incoming connection with a 554 error.
2732 Unfortunately, if there is a major crisis, such as a disk failure,
2733 tcp-wrappers gives "deny", whereas what one would like would be some
2734 kind of temporary error. A kludge has been added to help with this.
2735 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2736 554 error is used if errno is still zero or contains ENOENT (which occurs
2737 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2738 451 error is used.

2760PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
2761 folder from quota calculations, a direct delivery into this folder messed
2762 up the contents of the maildirsize file. This was because the regex was
2763 used only to exclude .Trash (or whatever) when the size of the mailbox
2764 was calculated. There was no check that a delivery was happening into an
2765 excluded directory. This bug has been fixed by ignoring all quota

2772-----------------
2773
2774PH/01 The code for finding all the local interface addresses on a FreeBSD
2775 system running IPv6 was broken. This may well have applied to all BSD
2776 systems, as well as to others that have similar system calls. The broken
2777 code found IPv4 interfaces correctly, but gave incorrect values for the
2778 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2779 that it would not match correctly against @[] and not recognize the IPv6
2780 addresses as local.

2790 invalid. However, $reply_address has leading white space removed, and all

2822 generate an autoreply, and therefore failed to obtain an address for the
2823 autoreply, Exim could try to deliver to a non-existent relative file
2824 name, causing unrelated and misleading errors. What now happens is that
2825 it logs this as a hard delivery error, but does not attempt to create a

2843 non-existent - all you got was a failure to exec. I have made two
2844 changes:

2847 in a subprocess such as that created by queryprogram now generate

PH
2857PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2858 additional section of a DNS packet that returns MX or SRV records.
2859 Instead, it always explicitly searches for A/AAAA records. This avoids
2860 major problems that occur when a DNS server includes only records of one
2861 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2862 fixed another bug: if SRV records were looked up and the corresponding
2863 address records were *not* found in the additional section, the port
2864 values from the SRV records were lost.

ea49d0e1
PH
2866PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

2869
064a94c9
PH
2870PH/18 If quota_warn_message contains a From: header, Exim now refrains from

2872 errors_reply_to option, if set, is not used.
2873
727071f8
PH
2874PH/19 When calculating a retry time, Exim used to measure the "time since
2875 failure" by looking at the "first failed" field in the retry record. Now
2876 it does not use this if it is later than than the arrival time of the
2877 message. Instead it uses the arrival time. This makes for better
2878 behaviour in cases where some deliveries succeed, thus re-setting the
2879 "first failed" field. An example is a quota failure for a huge message
2880 when small messages continue to be delivered. Without this change, the
2881 "time since failure" will always be short, possible causing more frequent
2882 delivery attempts for the huge message than are intended.

PH
2979PH/42 The content-scanning code uses fopen() to create files in which to put
2980 message data. Previously it was not paying any attention to the mode of
2981 the files. Exim runs with umask(0) because the rest of the code creates
2982 files with open(), and sets the required mode explicitly. Thus, these
2983 files were ending up world-writeable. This was not a big issue, because,
2984 being within the spool directory, they were not world-accessible. I have
2985 created a function called modefopen, which takes an additional mode
2986 argument. It sets umask(777), creates the file, chmods it to the required
2987 mode, then resets the umask. All the relevant calls to fopen() in the

3025
3026 (i) Exim was not creating retry information for temporary errors given
3027 for individual recipients after the DATA command when the smtp transport
3028 was used in LMTP mode. This meant that they could be retried too
3029 frequently, and not timed out correctly.
3030
3031 (ii) Exim was setting the flag that allows error details to be returned
3032 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3033 recipients that were returned after the DATA command.
3034
3035PH/53 This is related to PH/52, but is more general: for any failing address,
3036 when detailed error information was permitted to be returned to the
3037 sender, but the error was temporary, then after the final timeout, only
3038 "retry timeout exceeded" was returned. Now it returns the full error as

3083PH/63 Changed the macro HAVE_LOGIN_CAP (see PH/41 for this release above) to
3084 HAVE_SETCLASSRESOURCES because there are different APIs in use that all
3085 use login_cap.h, so on its own it isn't the distinguishing feature. The
3086 new name refers directly to the setclassresources() function.

3095PH/68 The bounce_return_message and bounce_return_body options were not being
3096 honoured for bounces generated during the reception of non-SMTP messages.
3097 In particular, this applied to messages rejected by the ACL. This bug has
3098 been fixed. However, if bounce_return_message is true and bounce_return_
3099 body is false, the headers that are returned for a non-SMTP message
3100 include only those that have been read before the error was detected.
3101 (In the case of an ACL rejection, they have all been read.)

3103PH/69 The HTML version of the specification is now built in a directory called

3109PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3110 function verify_get_ident() calls ip_connect() to connect a socket, but
3111 if the "connect()" function timed out, ip_connect() used to close the
3112 socket. However, verify_get_ident() also closes the socket later, and in
3113 between Exim writes to the log, which may get opened at this point. When
3114 the socket was closed in ip_connect(), the log could get the same file
3115 descriptor number as the socket. This naturally causes chaos. The fix is
3116 not to close the socket in ip_connect(); the socket should be closed by
3117 the function that creates it. There was only one place in the code where
3118 this was missing, in the iplookup router, which I don't think anybody now
3119 uses, but I've fixed it anyway.

3129PH/01 Two changes to the default runtime configuration:

3131 (1) Move the checks for relay_from_hosts and authenticated clients from
3132 after to before the (commented out) DNS black list checks.
3133
3134 (2) Add control=submission to the relay_from_hosts and authenticated
3135 clients checks, on the grounds that messages accepted by these
3136 statements are most likely to be submissions.

3138PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3139
3140 (1) Generate an error if the third argument for the ${prvs expansion is
3141 not a single digit.
3142
3143 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3144 string.
3145
3146 (3) Reset the variables that are obtained from the first argument of
3147 ${prvscheck and used in the second argument before leaving the code,
3148 because their memory is reclaimed, so using them afterwards may do
3149 silly things.
3150
3151 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3152 one (it's much easier than Tom thought :-).
3153
3154 (5) Because of (4), we can now allow for the use of $prvscheck_result
3155 inside the third argument.

3164PH/05 When a filter generated an autoreply, the entire To: header line was
3165 quoted in the delivery log line, like this:
3166
3167 => >A.N.Other <ano@some.domain> <original@ddress> ...
3168
3169 This has been changed so that it extracts the operative address. There
3170 may be more than one such address. If so, they are comma-separated, like
3171 this:
3172
3173 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
3175PH/06 When a client host used a correct literal IP address in a HELO or EHLO
3176 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3177 not being looked up in the rDNS to get a host name, Exim was showing the
3178 IP address twice in Received: lines, even though the IP addresses were
3179 identical. For example:
3180
3181 Received: from [1.2.3.4] (helo=[1.2.3.4])
3182
3183 However, if the real host name was known, it was omitting the HELO data
3184 if it matched the actual IP address. This has been tidied up so that it
3185 doesn't show the same IP address twice.

3187PH/07 When both +timestamp and +memory debugging was on, the value given by
3188 $tod_xxx expansions could be wrong, because the tod_stamp() function was
3189 called by the debug printing, thereby overwriting the timestamp buffer.
3190 Debugging no longer uses the tod_stamp() function when +timestamp is set.

3195 message.

3211PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
3212 Electronic Mail") by including:
3213
3214 Auto-submitted: auto-generated
3215
3216 in the messages that it generates (bounce messages and others, such as
4c04137d 3217 warnings). In the case of bounce messages for non-SMTP messages, there was
456682f5
PH
3218 also a typo: it was using "Auto_submitted" (underscore instead of
3219 hyphen). Since every message generated by Exim is necessarily in response
3220 to another message, thes have all been changed to:
3221
3222 Auto-Submitted: auto-replied
3223
3224 in accordance with these statements in the RFC:
3225
3226 The auto-replied keyword:
3227
3228 - SHOULD be used on messages sent in direct response to another
3229 message by an automatic process,
3230
3231 - MUST NOT be used on manually-generated messages,
3232
3233 - MAY be used on Delivery Status Notifications (DSNs) and Message
3234 Disposition Notifications (MDNs),
3235
3236 - MUST NOT be used on messages generated by automatic or periodic
3237 processes, except for messages which are automatic responses to
3238 other messages.

3259PH/17 A further patch from the Sieve maintainer: "Introduce the new Sieve
3260 extension "envelope-auth". The code is finished and in agreement with
3261 other implementations, but there is no documentation so far and in fact,
3262 nobody wrote the draft yet. This extension is currently #undef'ed, thus
3263 not changing the active code.
3264
3265 Print executed "if" and "elsif" statements when debugging is used. This
3266 helps a great deal to understand what a filter does.
3267
3268 Document more things not specified clearly in RFC3028. I had all this
3269 sorted out, when out of a sudden new issues came to my mind. Oops."

PH
3274PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
3275 canonical form (as documented). However, after a host name lookup from
3276 the IP address, check_host() was doing a simple string comparison with
3277 addresses acquired from the DNS when checking that the found name did
3278 have the original IP as one of its addresses. Since any found IPv6
3279 addresses are likely to be in abbreviated form, the comparison could
3280 fail. Luckily, there already exists a function for doing the comparison
3281 by converting both addresses to binary, so now that is used instead of
3282 the text comparison.
