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

16PP/01 GitHub PR 50: Do not call ldap_start_tls_s on ldapi:// connections.
17 Patch provided by "Björn", documentation fix added too.

JH
19JH/03 Bug 2003: fix Proxy Protocol v2 handling: the address size field was
20 missing a wire-to-host endian conversion.
21
f4630439
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.
26

JS
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.
47
eea19017
JH
48JH/09 Bug 2014: permit inclusion of a DKIM-Signature header in a received
49 DKIM signature block, for verification. Although advised against by
50 standards it is specifically not ruled illegal.
51
44e6651b
JH
52JH/10 Bug 2025: Fix reception of (quoted) local-parts with embedded spaces.
53
54JH/11 Bug 2029: Fix crash in DKIM verification when a message signature block is
55 missing a body hash (the bh= tag).
56
57JH/12 Bug 2018: Re-order Proxy Protocol startup versus TLS-on-connect startup.
58 It seems that HAProxy sends the Proxy Protocol information in clear and
59 only then does a TLS startup, so do the same.
60
61JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
62 TCP connections (such as for Spamd) unless the daemon successfully set
63 Fast Open mode on its listening sockets. This fixes breakage seen on
64 too-old kernels or those not configured for Fast Open, at the cost of
65 requiring both directions being enabled for TFO, and TFO never being used
66 by non-daemon-related Exim processes.
67
68JH/14 Bug 2000: Reject messages recieved with CHUNKING but with malformed line
69 endings, at least on the first header line. Try to canonify any that get
70 past that check, despite the cost.
71
b6040544
JH
72JH/15 Angle-bracket nesting (an error inserted by broken sendmails) levels are
73 now limited to an arbitrary five deep, while parsing addresses with the
74 strip_excess_angle_brackets option enabled.
75
f700ea4d
PP
76PP/03 Bug 2018: For Proxy Protocol and TLS-on-connect, do not over-read and
77 instead leave the unprompted TLS handshake in socket buffer for the
78 TLS library to consume.

82-----------------
4c57a40e 83
9094b84b
JH
84JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
85 supports it and a size is available (ie. the sending peer gave us one).
8d042305 86
03d5892b
JH
87JH/02 The obsolete acl condition "demime" is removed (finally, after ten
88 years of being deprecated). The replacements are the ACLs
89 acl_smtp_mime and acl_not_smtp_mime.
90
4b0fe319
JH
91JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
92 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
93 or even an in-clear connection were permitted. Now, if the host lookup
94 was dnssec and dane was requested then the host is only used if the
95 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
96 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
97 if one fails this test.
98 This means that a poorly-configured remote DNS will make it incommunicado;
99 but it protects against a DNS-interception attack on it.

JH
101JH/04 Bug 1810: make continued-use of an open smtp transport connection
102 non-noisy when a race steals the message being considered.

23bb6982 104JH/05 If main configuration option tls_certificate is unset, generate a
f59aaaaa 105 self-signed certificate for inbound TLS connections.

0bd1b1ed 107JH/06 Bug 165: hide more cases of password exposure - this time in expansions
f42deca9 108 in rewrites and routers.
0bd1b1ed 109
20b9a2dc
JH
110JH/07 Retire gnutls_require_mac et.al. These were nonfunctional since 4.80
111 and logged a warning sing 4.83; now they are a configuration file error.
112
05392bbc
JH
113JH/08 Bug 1836: Fix crash in VRFY handling when handed an unqualified name
114 (lacking @domain). Apply the same qualification processing as RCPT.
115

cfab9d68
JH
118JH/10 Support ${sha256:} applied to a string (as well as the previous
119 certificate).
120
98c82a3d
JH
121JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
122 a cutthrough deliver is pending, as we always want to make a connection.
123 This also avoids re-routing the message when later placing the cutthrough
124 connection after a verify cache hit.
125 Do not update it with the verify result either.
126
127JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
128 when routing results in more than one destination address.
129
ae8386f0
JH
130JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
131 signing (which inhibits the cutthrough capability). Previously only
132 the presence of an option was tested; now an expansion evaluating as
133 empty is permissible (obviously it should depend only on data available
134 when the cutthrough connection is made).
135
0d9fa8c0
JH
136JH/14 Fix logging of errors under PIPELINING. Previously the log line giving
137 the relevant preceding SMTP command did not note the pipelining mode.

139JH/15 Fix counting of empty lines in $body_linecount and $message_linecount.
140 Previously they were not counted.
141
ef3a1a30
JH
142JH/16 DANE: treat a TLSA lookup response having all non-TLSA RRs, the same
143 as one having no matching records. Previously we deferred the message
144 that needed the lookup.
145
4c04137d 146JH/17 Fakereject: previously logged as a normal message arrival "<="; now

150 for missing MX records. Previously it only worked for missing A records.

155 after the data-go-ahead and data-ack. Patch from Jason Betts.

4c04137d 157JH/21 Bug 1846: Send DMARC forensic reports for reject and quarantine results,
72a201e2
TM
158 even for a "none" policy. Patch from Tony Meyer.
159
1c788856
JH
160JH/22 Fix continued use of a connection for further deliveries. If a port was
161 specified by a router, it must also match for the delivery to be
162 compatible.
163
e3b1f624
JH
164JH/23 Bug 1874: fix continued use of a connection for further deliveries.
165 When one of the recipients of a message was unsuitable for the connection
166 (has no matching addresses), we lost track of needing to mark it
167 deferred. As a result mail would be lost.
168

JH
169JH/24 Bug 1832: Log EHLO response on getting conn-close response for HELO.
170
f59aaaaa 171JH/25 Decoding ACL controls is now done using a binary search; the source code
2d009132
JH
172 takes up less space and should be simpler to maintain. Merge the ACL
173 condition decode tables also, with similar effect.
d7bed771 174
d1f9fb42
JH
175JH/26 Fix problem with one_time used on a redirect router which returned the
176 parent address unchanged. A retry would see the parent address marked as
177 delivered, so not attempt the (identical) child. As a result mail would
178 be lost.

JH
180JH/27 Fix a possible security hole, wherein a process operating with the Exim
181 UID can gain a root shell. Credit to http://www.halfdog.net/ for
182 discovery and writeup. Ubuntu bug 1580454; no bug raised against Exim
183 itself :(

203 Exim did stdio operations after fclose. This was exposed by a recent
204 change which nulled out the file handle after the fclose.

206JH/32 Bug 1909: Fix OCSP proof verification for cases where the proof is
207 signed directly by the cert-signing cert, rather than an intermediate
208 OCSP-signing cert. This is the model used by LetsEncrypt.

JH
228JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
229 and 3.4.4 - once the server is enabled to respond to an OCSP request
230 it does even when not requested, resulting in a stapling non-aware
231 client dropping the TLS connection.

TF
236TF/02 Improve the consistency of logging incoming and outgoing interfaces.
237 The I= interface field on outgoing lines is now after the H= remote
238 host field, same as incoming lines. There is a separate
239 outgoing_interface log selector which allows you to disable the
240 outgoing I= field.
241
c8899c20
JH
242JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
243 If not running log_selector +smtp_connection the mainlog would be held
244 open indefinitely after a "too many connections" event, including to a
245 deleted file after a log rotate. Leave the per net connection logging
246 leaving it open for efficiency as that will be quickly detected by the
247 check on the next write.

HSHR
249HS/01 Bug 1671: Fix post transport crash.
250 Processing the wait-<transport> messages could crash the delivery
251 process if the message IDs didn't exist for some reason. When
252 using 'split_spool_directory=yes' the construction of the spool
253 file name failed already, exposing the same netto behaviour.

259 to DSN fail messages (bounces): remote IP, remote greeting, remote response
260 to HELO, local diagnostic string.
261
805bb5c3
JH
262JH/05 Downgrade message for a TLS-certificate-based authentication fail from
263 log line to debug. Even when configured with a tls authenticator many
264 client connections are expected to not authenticate in this way, so
265 an authenticate fail is not an error.

JH
273JH/07 Bug 1678: Always record an interface option value, if set, as part of a

JH
302JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
303 defaults to "*" (all hosts). The variable is now available when not built
4c04137d 304 with TLS, default unset, mainly to enable keeping the testsuite sane.
23f3dc67
JH
305 If a server certificate is not supplied (via tls_certificate) an error is
306 logged, and clients will find TLS connections fail on startup. Presumably
307 they will retry in-clear.
308 Packagers of Exim are strongly encouraged to create a server certificate
309 at installation time.

314JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
315 in transport context, after the attempt, and per-recipient. The latter type
316 is per host attempted. The event data is the error message, and the errno
317 information encodes the lookup type (A vs. MX) used for the (first) host,
4c04137d 318 and the trailing two digits of the smtp 4xx response.

320GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
321 to write to mainlog (or rejectlog, paniclog) in the window between file
322 creation and permissions/ownership being changed. Particularly affects
323 installations where exicyclog is run as root, rather than exim user;
324 result is that the running daemon panics and dies.

JH
364JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
365 support, by using OpenSSL or GnuTLS library ones. This means DKIM is
07c73177
JH
366 only supported when built with TLS support. The PolarSSL SHA routines
367 are still used when the TLS library is too old for convenient support.

JH
380JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
381 incorrectly not doubled on cutthrough transmission, hence seen as a
382 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 383 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
384 via the normal store-and-forward channel. This could result in duplicates
385 received - but deduplicating mailstores were liable to retain only the
386 initial truncated version.

913TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
914
915 When a queue runner is handling a message, Exim first routes the
916 recipient addresses, during which it prunes them based on the retry
917 hints database. After that it attempts to deliver the message to
918 any remaining recipients. It then updates the hints database using
919 the retry rules.
920
921 So if a recipient address works intermittently, it can get repeatedly
922 deferred at routing time. The retry hints record remains fresh so the
923 address never reaches the final cutoff time.
924
925 This is a fairly common occurrence when a user is bumping up against
926 their storage quota. Exim had some logic in its local delivery code
927 to deal with this. However it did not apply to per-recipient defers
928 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
929
1ddeb334
TF
930 This change adds a proper retry rule check during routing so that the
931 final cutoff time is checked against the message's age. We only do
932 this check if there is an address retry record and there is not a
933 domain retry record; this implies that previous attempts to handle
934 the address had the retry_use_local_parts option turned on. We use
935 this as an approximation for the destination being like a local
936 delivery, as in LMTP.
67bd1ab3
TF
937
938 I suspect this new check makes the old local delivery cutoff check
939 redundant, but I have not verified this so I left the code in place.

946
947 When I ran the test suite under the user fanf2, Exim expanded
948 the header to contain my full name, whereas it should have added
949 a Resent-Sender: header. It erroneously treats any prefix of the
950 username as equal to the username.

975 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
976 config variable "prdr_enable" controls whether the server
977 advertises the facility. If the client requests PRDR a new
978 acl_data_smtp_prdr ACL is called once for each recipient, after
979 the body content is received and before the acl_smtp_data ACL.
4c04137d 980 The client is controlled by both of: a hosts_try_prdr option

TF
1261TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1262 lock up or crash if it happened to be inside a call to libc when it
1263 got a SIGUSR1 from exiwhat.
1264
1265 The SIGUSR1 handler appends the current process status to the process
1266 log which is later printed by exiwhat. It used to use the general
1267 purpose logging code to do this, but several functions it calls are
1268 not safe for signals.
1269
1270 The new output code in the SIGUSR1 handler is specific to the process
1271 log, and simple enough that it's easy to inspect for signal safety.
1272 Removing some special cases also simplifies the general logging code.
1273 Removing the spurious timestamps from the process log simplifies
1274 exiwhat.
1275
c99ce5c9
TF
1276TF/04 Improved ratelimit ACL condition.
1277
1278 The /noupdate option has been deprecated in favour of /readonly which
1279 has clearer semantics. The /leaky, /strict, and /readonly update modes
1280 are mutually exclusive. The update mode is no longer included in the
1281 database key; it just determines when the database is updated. (This
4c04137d 1282 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1283
1284 Exim now checks that the per_* options are used with an update mode that
1285 makes sense for the current ACL. For example, when Exim is processing a
1286 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1287 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1288 must specify per_mail/readonly. If you omit the update mode it defaults to
1289 /leaky where that makes sense (as before) or /readonly where required.
1290
1291 The /noupdate option is now undocumented but still supported for
1292 backwards compatibility. It is equivalent to /readonly except that in
1293 ACLs where /readonly is required you may specify /leaky/noupdate or
1294 /strict/noupdate which are treated the same as /readonly.
1295
1296 A useful new feature is the /count= option. This is a generalization
1297 of the per_byte option, so that you can measure the throughput of other
1298 aggregate values. For example, the per_byte option is now equivalent
1299 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1300
1301 The per_rcpt option has been generalized using the /count= mechanism
1302 (though it's more complicated than the per_byte equivalence). When it is
1303 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1304 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1305 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1306 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1307 Note that using per_rcpt with a non-readonly update mode in more than
1308 one ACL will cause the recipients to be double-counted. (The per_mail
1309 and per_byte options don't have this problem.)
1310
1311 The handling of very low rates has changed slightly. If the computed rate
1312 is less than the event's count (usually one) then this event is the first
1313 after a long gap. In this case the rate is set to the same as this event's
1314 count, so that the first message of a spam run is counted properly.
1315
1316 The major new feature is a mechanism for counting the rate of unique
1317 events. The new per_addr option counts the number of different
1318 recipients that someone has sent messages to in the last time period. It
1319 behaves like per_rcpt if all the recipient addresses are different, but
1320 duplicate recipient addresses do not increase the measured rate. Like
1321 the /count= option this is a general mechanism, so the per_addr option
1322 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1323 example, measure the rate that a client uses different sender addresses
1324 with the options per_mail/unique=$sender_address. There are further
1325 details in the main documentation.

1897PH/01 Another patch from the Sieve maintainer.
1898
6a3bceb1
PH
1899PH/02 When an IPv6 address is converted to a string for single-key lookup
1900 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1901 dots are used instead of colons so that keys in lsearch files need not
1902 contain colons. This was done some time before quoting was made available
1903 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1904 (notated using the quote facility) so as to distinguish them from IPv4
1905 keys. This meant that lookups for IP addresses in host lists did not work
1906 for iplsearch lookups.
1907
1908 This has been fixed by arranging for IPv6 addresses to be expressed with
1909 colons if the lookup type is iplsearch. This is not incompatible, because
1910 previously such lookups could never work.
1911
4c04137d 1912 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
1913 ordinary lsearch keys. However, making the change in all cases is
1914 incompatible and would probably break a number of configurations.

1919MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1920 conversion specification without a maximum field width, thereby enabling
1921 a rogue spamd server to cause a buffer overflow. While nobody in their
1922 right mind would setup Exim to query an untrusted spamd server, an
1923 attacker that gains access to a server running spamd could potentially
1924 exploit this vulnerability to run arbitrary code as the Exim user.

1930 a directory entry by the name of the lookup key. Previously, if a

1932 Exim lacked permissions to read, a lookup for a key matching that

2120 some time before the response is written. In this time, more input might
2121 arrive, invalidly. So now there are extra checks after an ACL has run for
2122 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2123 pipelining has not been advertised.

PH
2197 the response to the final '.' that terminates a message, but only in the
2198 case where the client has not sent further data following the '.'
2199 (unfortunately, this is allowed). However, in many cases there won't be
2200 any further data because there won't be any more messages to send. A call
2201 to select() can be used: if it shows that the input is "ready", there is
2202 either input waiting, or the socket has been closed. An attempt to read
2203 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2204 would have sent an OK response which the client would never have see.

2215PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2216 fixed by 4.65/MH/01 (is this a record?) are fixed:
2217
2218 (i) An empty string was always treated as zero by the numeric comparison
2219 operators. This behaviour has been restored.
2220
2221 (ii) It is documented that the numeric comparison operators always treat
2222 their arguments as decimal numbers. This was broken in that numbers
2223 starting with 0 were being interpreted as octal.
2224
2225 While fixing these problems I realized that there was another issue that
2226 hadn't been noticed. Values of message_size_limit (both the global option
2227 and the transport option) were treated as octal if they started with 0.
2228 The documentation was vague. These values are now always treated as
2229 decimal, and I will make that clear in the documentation.

2b1c6e3a
PH
2273PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2274 callout verification, Exim cached a "reject" for the entire domain. This
2275 is correct for most verifications, but it is not correct for a recipient
2276 verification with use_sender or use_postmaster set, because in that case
2277 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2278 case of MAIL FROM:<> rejection from other early rejections (e.g.
2279 rejection of HELO). When verifying a recipient using a non-null MAIL
2280 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2281 Whatever the result of the callout, the value of the domain cache is
2282 left unchanged (for any other kind of callout, getting as far as trying
2283 RCPT means that the domain itself is ok).

2317PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2318 hostname. This is wrong, because it relates to the incoming message (and
2319 probably the interface on which it is arriving) and not to the outgoing
2320 callout (which could be using a different interface). This has been
2321 changed to use the value of the helo_data option from the smtp transport
2322 instead - this is what is used when a message is actually being sent. If
2323 there is no remote transport (possible with a router that sets up host
2324 addresses), $smtp_active_hostname is used.

14aa5a05 2326PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2327 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2328 (a) The code assumed that strncpy() returns a negative number on buffer
2329 overflow, which isn't the case. Replaced with Exim's string_format()
2330 function.
2331 (b) There were several signed/unsigned issues. I just did the minimum
2332 hacking in of casts. There is scope for a larger refactoring.
2333 (c) The code used strcasecmp() which is not a standard C function.
2334 Replaced with Exim's strcmpic() function.
2335 (d) The code set only $1; it now sets $auth1 as well.
2336 (e) A simple test gave the error "authentication client didn't specify
2337 service in request". It would seem that Dovecot has changed its
2338 interface. Fortunately there's a specification; I followed it and
2339 changed what the client sends and it appears to be working now.

PH
2344PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2345 address A is aliased to B and C, where B exists and C does not. Without
2346 -v the output is "A verified" because verification stops after a
2347 successful redirection if more than one address is generated. However,
2348 with -v the child addresses are also verified. Exim was outputting "A
2349 failed to verify" and then showing the successful verification for C,
2350 with its parentage. It now outputs "B failed to verify", showing B's
2351 parentage before showing the successful verification of C.

2353PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
2354 look up a TXT record in a specific list after matching in a combined
2355 list.
2356
322050c2
PH
2357PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2358 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2359 they consult the DNS. I had assumed they would set it the way they
2360 wanted; and indeed my experiments on Linux seem to show that in some
2361 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2362 To be on the safe side, however, I have now made the interface to
2363 host_find_byname() similar to host_find_bydns(), with an argument
2364 containing the DNS resolver options. The host_find_byname() function now
2365 sets these options at its start, just as host_find_bydns() does. The smtp
2366 transport options dns_qualify_single and dns_search_parents are passed to
2367 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2368 of host_find_byname() use the default settings of RES_DEFNAMES
2369 (qualify_single) but not RES_DNSRCH (search_parents).

PH
2371PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2372 spool_read_header() do less string testing, by means of a preliminary
2373 switch on the second character of optional "-foo" lines. (This is
2374 overdue, caused by the large number of possibilities that now exist.
2375 Originally there were few.) While I was there, I also converted the
2376 str(n)cmp tests so they don't re-test the leading "-" and the first
2377 character, in the hope this might squeeze out yet more improvement.
2378

PH
2379PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2380 flag allowing group syntax was set by the header_syntax check but not
2381 turned off, possible causing trouble later; (2) The flag was not being
2382 set at all for the header_verify test, causing "group"-style headers to
2383 be rejected. I have now set it in this case, and also caused header_
2384 verify to ignore an empty address taken from a group. While doing this, I
2385 came across some other cases where the code for allowing group syntax
2386 while scanning a header line wasn't quite right (mostly, not resetting
2387 the flag correctly in the right place). These bugs could have caused
2388 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
2390PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2391 with the "reply" argument non-NULL. The code, however (which originally
2392 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2393 but it didn't always do it. This confused somebody who was copying the
2394 code for some other use. I have removed all the tests.
2395
411ef850
PH
2396PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2397 feature that was used to support insecure browsers during the U.S. crypto
2398 embargo. It requires special client support, and Exim is probably the
2399 only MTA that supported it -- and would never use it because real RSA is
2400 always available. This code has been removed, because it had the bad
2401 effect of slowing Exim down by computing (never used) parameters for the
2402 RSA_EXPORT functionality.
2403
7befa435
PH
2404PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2405 authenticator to fail if there's a tab character in the incoming data
2406 (there should never be unless someone is messing about, as it's supposed
2407 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2408 if the connection is using TLS or if the remote IP is the same as the
2409 local IP, and the "valid-client-cert option" if a client certificate has
2410 been verified.

PH
2441
2442PH/30 Exim was sometimes attempting to deliver messages that had suffered
2443 address errors (4xx response to RCPT) over the same connection as other
2444 messages routed to the same hosts. Such deliveries are always "forced",
2445 so retry times are not inspected. This resulted in far too many retries
2446 for the affected addresses. The effect occurred only when there were more
2447 hosts than the hosts_max_try setting in the smtp transport when it had
2448 the 4xx errors. Those hosts that it had tried were not added to the list
2449 of hosts for which the message was waiting, so if all were tried, there
2450 was no problem. Two fixes have been applied:
2451
2452 (i) If there are any address or message errors in an SMTP delivery, none
2453 of the hosts (tried or untried) are now added to the list of hosts
2454 for which the message is waiting, so the message should not be a
2455 candidate for sending over the same connection that was used for a
2456 successful delivery of some other message. This seems entirely
2457 reasonable: after all the message is NOT "waiting for some host".
2458 This is so "obvious" that I'm not sure why it wasn't done
2459 previously. Hope I haven't missed anything, but it can't do any
2460 harm, as the worst effect is to miss an optimization.
2461
2462 (ii) If, despite (i), such a delivery is accidentally attempted, the
2463 routing retry time is respected, so at least it doesn't keep
2464 hammering the server.

2479PH/35 The error "getsockname() failed: connection reset by peer" was being
2480 written to the panic log as well as the main log, but it isn't really

2482 removed the panic log writing for the ECONNRESET error when getsockname()
2483 fails.
2484
48c7f9e2
PH
2485PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2486 runs only) independently of the message's sender address. This meant
2487 that, if the 4xx error was in fact related to the sender, a different
2488 message to the same recipient with a different sender could confuse
4c04137d 2489 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2490 server, but other circumstances could also provoke similar problems.
2491 I have changed the default so that the retry time for these errors is now
2492 based a combination of the sender and recipient addresses. This change
2493 can be overridden by setting address_retry_include_sender=false in the
2494 smtp transport.

2762PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2764 Unfortunately, if there is a major crisis, such as a disk failure,
2765 tcp-wrappers gives "deny", whereas what one would like would be some
2766 kind of temporary error. A kludge has been added to help with this.
2767 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2768 554 error is used if errno is still zero or contains ENOENT (which occurs
2769 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2770 451 error is used.

2806PH/01 The code for finding all the local interface addresses on a FreeBSD
2807 system running IPv6 was broken. This may well have applied to all BSD
2808 systems, as well as to others that have similar system calls. The broken
2809 code found IPv4 interfaces correctly, but gave incorrect values for the
2810 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2811 that it would not match correctly against @[] and not recognize the IPv6
2812 addresses as local.

2855 autoreply, Exim could try to deliver to a non-existent relative file

2891 Instead, it always explicitly searches for A/AAAA records. This avoids
2892 major problems that occur when a DNS server includes only records of one
2893 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2894 fixed another bug: if SRV records were looked up and the corresponding
2895 address records were *not* found in the additional section, the port
2896 values from the SRV records were lost.

PH
2906PH/19 When calculating a retry time, Exim used to measure the "time since
2907 failure" by looking at the "first failed" field in the retry record. Now
2908 it does not use this if it is later than than the arrival time of the
2909 message. Instead it uses the arrival time. This makes for better
2910 behaviour in cases where some deliveries succeed, thus re-setting the
2911 "first failed" field. An example is a quota failure for a huge message
2912 when small messages continue to be delivered. Without this change, the
2913 "time since failure" will always be short, possible causing more frequent
2914 delivery attempts for the huge message than are intended.

3011PH/42 The content-scanning code uses fopen() to create files in which to put
3012 message data. Previously it was not paying any attention to the mode of

3014 files with open(), and sets the required mode explicitly. Thus, these
3015 files were ending up world-writeable. This was not a big issue, because,
3016 being within the spool directory, they were not world-accessible. I have
3017 created a function called modefopen, which takes an additional mode
3018 argument. It sets umask(777), creates the file, chmods it to the required
3019 mode, then resets the umask. All the relevant calls to fopen() in the

3060 was used in LMTP mode. This meant that they could be retried too
3061 frequently, and not timed out correctly.
3062
3063 (ii) Exim was setting the flag that allows error details to be returned
3064 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3065 recipients that were returned after the DATA command.
3066
3067PH/53 This is related to PH/52, but is more general: for any failing address,
3068 when detailed error information was permitted to be returned to the

3110 verification continued, and the new address failed or deferred after
3111 having set something in $address_data, the value of $address_data was not
3112 passed back to the ACL. This was different to the case when no

3127PH/68 The bounce_return_message and bounce_return_body options were not being
3128 honoured for bounces generated during the reception of non-SMTP messages.
3129 In particular, this applied to messages rejected by the ACL. This bug has
3130 been fixed. However, if bounce_return_message is true and bounce_return_
3131 body is false, the headers that are returned for a non-SMTP message
3132 include only those that have been read before the error was detected.
3133 (In the case of an ACL rejection, they have all been read.)

3141PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3142 function verify_get_ident() calls ip_connect() to connect a socket, but
3143 if the "connect()" function timed out, ip_connect() used to close the
3144 socket. However, verify_get_ident() also closes the socket later, and in
3145 between Exim writes to the log, which may get opened at this point. When
3146 the socket was closed in ip_connect(), the log could get the same file
3147 descriptor number as the socket. This naturally causes chaos. The fix is
3148 not to close the socket in ip_connect(); the socket should be closed by
3149 the function that creates it. There was only one place in the code where
3150 this was missing, in the iplookup router, which I don't think anybody now
3151 uses, but I've fixed it anyway.

3166 (2) Add control=submission to the relay_from_hosts and authenticated
3167 clients checks, on the grounds that messages accepted by these
3168 statements are most likely to be submissions.

3170PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3171
3172 (1) Generate an error if the third argument for the ${prvs expansion is
3173 not a single digit.
3174
3175 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3176 string.
3177
3178 (3) Reset the variables that are obtained from the first argument of
3179 ${prvscheck and used in the second argument before leaving the code,
3180 because their memory is reclaimed, so using them afterwards may do
3181 silly things.
3182
3183 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3184 one (it's much easier than Tom thought :-).
3185
3186 (5) Because of (4), we can now allow for the use of $prvscheck_result
3187 inside the third argument.

3196PH/05 When a filter generated an autoreply, the entire To: header line was
3197 quoted in the delivery log line, like this:
3198
3199 => >A.N.Other <ano@some.domain> <original@ddress> ...
3200
3201 This has been changed so that it extracts the operative address. There
3202 may be more than one such address. If so, they are comma-separated, like
3203 this:
3204
3205 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
3207PH/06 When a client host used a correct literal IP address in a HELO or EHLO
3208 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3209 not being looked up in the rDNS to get a host name, Exim was showing the
3210 IP address twice in Received: lines, even though the IP addresses were
3211 identical. For example:
3212
3213 Received: from [1.2.3.4] (helo=[1.2.3.4])
3214
3215 However, if the real host name was known, it was omitting the HELO data
3216 if it matched the actual IP address. This has been tidied up so that it
3217 doesn't show the same IP address twice.

3219PH/07 When both +timestamp and +memory debugging was on, the value given by

3248 in the messages that it generates (bounce messages and others, such as

456682f5
PH
3250 also a typo: it was using "Auto_submitted" (underscore instead of
3251 hyphen). Since every message generated by Exim is necessarily in response
3252 to another message, thes have all been changed to:
3253
3254 Auto-Submitted: auto-replied
3255
3256 in accordance with these statements in the RFC:
3257
3258 The auto-replied keyword:
3259
3260 - SHOULD be used on messages sent in direct response to another
3261 message by an automatic process,
3262
3263 - MUST NOT be used on manually-generated messages,
3264
3265 - MAY be used on Delivery Status Notifications (DSNs) and Message
3266 Disposition Notifications (MDNs),
3267
3268 - MUST NOT be used on messages generated by automatic or periodic
3269 processes, except for messages which are automatic responses to
3270 other messages.
