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

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

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

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.

JH
80JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
81 supports it and a size is available (ie. the sending peer gave us one).
8d042305 82
03d5892b
JH
83JH/02 The obsolete acl condition "demime" is removed (finally, after ten
84 years of being deprecated). The replacements are the ACLs
85 acl_smtp_mime and acl_not_smtp_mime.
86
4b0fe319
JH
87JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
88 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
89 or even an in-clear connection were permitted. Now, if the host lookup
90 was dnssec and dane was requested then the host is only used if the
91 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
92 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
93 if one fails this test.
94 This means that a poorly-configured remote DNS will make it incommunicado;
95 but it protects against a DNS-interception attack on it.
96

97JH/04 Bug 1810: make continued-use of an open smtp transport connection
98 non-noisy when a race steals the message being considered.

f59aaaaa 101 self-signed certificate for inbound TLS connections.

106JH/07 Retire gnutls_require_mac et.al. These were nonfunctional since 4.80
107 and logged a warning sing 4.83; now they are a configuration file error.

JH
117JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
118 a cutthrough deliver is pending, as we always want to make a connection.
119 This also avoids re-routing the message when later placing the cutthrough
120 connection after a verify cache hit.
121 Do not update it with the verify result either.
122
123JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
124 when routing results in more than one destination address.
125
ae8386f0
JH
126JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
127 signing (which inhibits the cutthrough capability). Previously only
128 the presence of an option was tested; now an expansion evaluating as
129 empty is permissible (obviously it should depend only on data available
130 when the cutthrough connection is made).

132JH/14 Fix logging of errors under PIPELINING. Previously the log line giving
133 the relevant preceding SMTP command did not note the pipelining mode.

138JH/16 DANE: treat a TLSA lookup response having all non-TLSA RRs, the same
139 as one having no matching records. Previously we deferred the message
140 that needed the lookup.

JH
156JH/22 Fix continued use of a connection for further deliveries. If a port was
157 specified by a router, it must also match for the delivery to be
158 compatible.
159
e3b1f624
JH
160JH/23 Bug 1874: fix continued use of a connection for further deliveries.
161 When one of the recipients of a message was unsuitable for the connection
162 (has no matching addresses), we lost track of needing to mark it
163 deferred. As a result mail would be lost.

165JH/24 Bug 1832: Log EHLO response on getting conn-close response for HELO.

f59aaaaa 167JH/25 Decoding ACL controls is now done using a binary search; the source code
2d009132
JH
168 takes up less space and should be simpler to maintain. Merge the ACL
169 condition decode tables also, with similar effect.
d7bed771 170
d1f9fb42
JH
171JH/26 Fix problem with one_time used on a redirect router which returned the
172 parent address unchanged. A retry would see the parent address marked as
173 delivered, so not attempt the (identical) child. As a result mail would
174 be lost.

224JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
225 and 3.4.4 - once the server is enabled to respond to an OCSP request
226 it does even when not requested, resulting in a stapling non-aware

232TF/02 Improve the consistency of logging incoming and outgoing interfaces.
233 The I= interface field on outgoing lines is now after the H= remote

236 outgoing I= field.

238JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
239 If not running log_selector +smtp_connection the mainlog would be held
240 open indefinitely after a "too many connections" event, including to a
241 deleted file after a log rotate. Leave the per net connection logging
242 leaving it open for efficiency as that will be quickly detected by the
243 check on the next write.

JH
258JH/05 Downgrade message for a TLS-certificate-based authentication fail from

312 is per host attempted. The event data is the error message, and the errno
313 information encodes the lookup type (A vs. MX) used for the (first) host,
4c04137d 314 and the trailing two digits of the smtp 4xx response.

909TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
910
911 When a queue runner is handling a message, Exim first routes the
912 recipient addresses, during which it prunes them based on the retry
913 hints database. After that it attempts to deliver the message to
914 any remaining recipients. It then updates the hints database using
915 the retry rules.
916
917 So if a recipient address works intermittently, it can get repeatedly
918 deferred at routing time. The retry hints record remains fresh so the
919 address never reaches the final cutoff time.
920
921 This is a fairly common occurrence when a user is bumping up against
922 their storage quota. Exim had some logic in its local delivery code
923 to deal with this. However it did not apply to per-recipient defers
924 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
925
1ddeb334
TF
926 This change adds a proper retry rule check during routing so that the
927 final cutoff time is checked against the message's age. We only do
928 this check if there is an address retry record and there is not a
929 domain retry record; this implies that previous attempts to handle
930 the address had the retry_use_local_parts option turned on. We use
931 this as an approximation for the destination being like a local
932 delivery, as in LMTP.
67bd1ab3
TF
933
934 I suspect this new check makes the old local delivery cutoff check
935 redundant, but I have not verified this so I left the code in place.

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

1257TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1258 lock up or crash if it happened to be inside a call to libc when it
1259 got a SIGUSR1 from exiwhat.
1260
1261 The SIGUSR1 handler appends the current process status to the process
1262 log which is later printed by exiwhat. It used to use the general
1263 purpose logging code to do this, but several functions it calls are
1264 not safe for signals.
1265
1266 The new output code in the SIGUSR1 handler is specific to the process
1267 log, and simple enough that it's easy to inspect for signal safety.
1268 Removing some special cases also simplifies the general logging code.
1269 Removing the spurious timestamps from the process log simplifies
1270 exiwhat.
1271
c99ce5c9
TF
1272TF/04 Improved ratelimit ACL condition.
1273
1274 The /noupdate option has been deprecated in favour of /readonly which
1275 has clearer semantics. The /leaky, /strict, and /readonly update modes
1276 are mutually exclusive. The update mode is no longer included in the
1277 database key; it just determines when the database is updated. (This
4c04137d 1278 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1279
1280 Exim now checks that the per_* options are used with an update mode that
1281 makes sense for the current ACL. For example, when Exim is processing a
1282 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1283 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1284 must specify per_mail/readonly. If you omit the update mode it defaults to
1285 /leaky where that makes sense (as before) or /readonly where required.
1286
1287 The /noupdate option is now undocumented but still supported for
1288 backwards compatibility. It is equivalent to /readonly except that in
1289 ACLs where /readonly is required you may specify /leaky/noupdate or
1290 /strict/noupdate which are treated the same as /readonly.
1291
1292 A useful new feature is the /count= option. This is a generalization
1293 of the per_byte option, so that you can measure the throughput of other
1294 aggregate values. For example, the per_byte option is now equivalent
1295 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1296
1297 The per_rcpt option has been generalized using the /count= mechanism
1298 (though it's more complicated than the per_byte equivalence). When it is
1299 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1300 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1301 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1302 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1303 Note that using per_rcpt with a non-readonly update mode in more than
1304 one ACL will cause the recipients to be double-counted. (The per_mail
1305 and per_byte options don't have this problem.)
1306
1307 The handling of very low rates has changed slightly. If the computed rate
1308 is less than the event's count (usually one) then this event is the first
1309 after a long gap. In this case the rate is set to the same as this event's
1310 count, so that the first message of a spam run is counted properly.
1311
1312 The major new feature is a mechanism for counting the rate of unique
1313 events. The new per_addr option counts the number of different
1314 recipients that someone has sent messages to in the last time period. It
1315 behaves like per_rcpt if all the recipient addresses are different, but
1316 duplicate recipient addresses do not increase the measured rate. Like
1317 the /count= option this is a general mechanism, so the per_addr option
1318 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1319 example, measure the rate that a client uses different sender addresses
1320 with the options per_mail/unique=$sender_address. There are further
1321 details in the main documentation.

1891-----------------
1892
1893PH/01 Another patch from the Sieve maintainer.
1894
6a3bceb1
PH
1895PH/02 When an IPv6 address is converted to a string for single-key lookup
1896 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1897 dots are used instead of colons so that keys in lsearch files need not
1898 contain colons. This was done some time before quoting was made available
1899 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1900 (notated using the quote facility) so as to distinguish them from IPv4
1901 keys. This meant that lookups for IP addresses in host lists did not work
1902 for iplsearch lookups.
1903
1904 This has been fixed by arranging for IPv6 addresses to be expressed with
1905 colons if the lookup type is iplsearch. This is not incompatible, because
1906 previously such lookups could never work.
1907
4c04137d 1908 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
1909 ordinary lsearch keys. However, making the change in all cases is
1910 incompatible and would probably break a number of configurations.

MH
1915MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1916 conversion specification without a maximum field width, thereby enabling
1917 a rogue spamd server to cause a buffer overflow. While nobody in their
1918 right mind would setup Exim to query an untrusted spamd server, an
1919 attacker that gains access to a server running spamd could potentially
1920 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1925MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1926 a directory entry by the name of the lookup key. Previously, if a

2113PH/29 SMTP synchronization checks are implemented when a command is read -

2116 some time before the response is written. In this time, more input might
2117 arrive, invalidly. So now there are extra checks after an ACL has run for
2118 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2119 pipelining has not been advertised.

PH
2193 the response to the final '.' that terminates a message, but only in the
2194 case where the client has not sent further data following the '.'
2195 (unfortunately, this is allowed). However, in many cases there won't be
2196 any further data because there won't be any more messages to send. A call
2197 to select() can be used: if it shows that the input is "ready", there is
2198 either input waiting, or the socket has been closed. An attempt to read
2199 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2200 would have sent an OK response which the client would never have see.

2211PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2212 fixed by 4.65/MH/01 (is this a record?) are fixed:
2213
2214 (i) An empty string was always treated as zero by the numeric comparison
2215 operators. This behaviour has been restored.
2216
2217 (ii) It is documented that the numeric comparison operators always treat
2218 their arguments as decimal numbers. This was broken in that numbers
2219 starting with 0 were being interpreted as octal.
2220
2221 While fixing these problems I realized that there was another issue that
2222 hadn't been noticed. Values of message_size_limit (both the global option
2223 and the transport option) were treated as octal if they started with 0.
2224 The documentation was vague. These values are now always treated as
2225 decimal, and I will make that clear in the documentation.

2242 large number of recipients for a single message is ridiculous

PH
2269PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2270 callout verification, Exim cached a "reject" for the entire domain. This
2271 is correct for most verifications, but it is not correct for a recipient
2272 verification with use_sender or use_postmaster set, because in that case
2273 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2274 case of MAIL FROM:<> rejection from other early rejections (e.g.
2275 rejection of HELO). When verifying a recipient using a non-null MAIL
2276 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2277 Whatever the result of the callout, the value of the domain cache is
2278 left unchanged (for any other kind of callout, getting as far as trying
2279 RCPT means that the domain itself is ok).

2315 probably the interface on which it is arriving) and not to the outgoing
2316 callout (which could be using a different interface). This has been
2317 changed to use the value of the helo_data option from the smtp transport
2318 instead - this is what is used when a message is actually being sent. If
2319 there is no remote transport (possible with a router that sets up host
2320 addresses), $smtp_active_hostname is used.

14aa5a05 2322PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2323 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2324 (a) The code assumed that strncpy() returns a negative number on buffer
2325 overflow, which isn't the case. Replaced with Exim's string_format()
2326 function.
2327 (b) There were several signed/unsigned issues. I just did the minimum
2328 hacking in of casts. There is scope for a larger refactoring.
2329 (c) The code used strcasecmp() which is not a standard C function.
2330 Replaced with Exim's strcmpic() function.
2331 (d) The code set only $1; it now sets $auth1 as well.
2332 (e) A simple test gave the error "authentication client didn't specify
2333 service in request". It would seem that Dovecot has changed its
2334 interface. Fortunately there's a specification; I followed it and
2335 changed what the client sends and it appears to be working now.

PH
2340PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2341 address A is aliased to B and C, where B exists and C does not. Without
2342 -v the output is "A verified" because verification stops after a
2343 successful redirection if more than one address is generated. However,
2344 with -v the child addresses are also verified. Exim was outputting "A
2345 failed to verify" and then showing the successful verification for C,
2346 with its parentage. It now outputs "B failed to verify", showing B's
2347 parentage before showing the successful verification of C.

2349PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
2350 look up a TXT record in a specific list after matching in a combined
2351 list.
2352
322050c2
PH
2353PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2354 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2355 they consult the DNS. I had assumed they would set it the way they
2356 wanted; and indeed my experiments on Linux seem to show that in some
2357 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2358 To be on the safe side, however, I have now made the interface to
2359 host_find_byname() similar to host_find_bydns(), with an argument
2360 containing the DNS resolver options. The host_find_byname() function now
2361 sets these options at its start, just as host_find_bydns() does. The smtp
2362 transport options dns_qualify_single and dns_search_parents are passed to
2363 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2364 of host_find_byname() use the default settings of RES_DEFNAMES
2365 (qualify_single) but not RES_DNSRCH (search_parents).
2366

PH
2367PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2368 spool_read_header() do less string testing, by means of a preliminary
2369 switch on the second character of optional "-foo" lines. (This is
2370 overdue, caused by the large number of possibilities that now exist.
2371 Originally there were few.) While I was there, I also converted the
2372 str(n)cmp tests so they don't re-test the leading "-" and the first
2373 character, in the hope this might squeeze out yet more improvement.
2374

PH
2375PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2376 flag allowing group syntax was set by the header_syntax check but not
2377 turned off, possible causing trouble later; (2) The flag was not being
2378 set at all for the header_verify test, causing "group"-style headers to
2379 be rejected. I have now set it in this case, and also caused header_
2380 verify to ignore an empty address taken from a group. While doing this, I
2381 came across some other cases where the code for allowing group syntax
2382 while scanning a header line wasn't quite right (mostly, not resetting
2383 the flag correctly in the right place). These bugs could have caused
2384 trouble for malformed header lines. I hope it is now all correct.
2385
602e59e5
PH
2386PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2387 with the "reply" argument non-NULL. The code, however (which originally
2388 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2389 but it didn't always do it. This confused somebody who was copying the
2390 code for some other use. I have removed all the tests.
2391
411ef850
PH
2392PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2393 feature that was used to support insecure browsers during the U.S. crypto
2394 embargo. It requires special client support, and Exim is probably the
2395 only MTA that supported it -- and would never use it because real RSA is
2396 always available. This code has been removed, because it had the bad
2397 effect of slowing Exim down by computing (never used) parameters for the
2398 RSA_EXPORT functionality.
2399
7befa435
PH
2400PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2401 authenticator to fail if there's a tab character in the incoming data
2402 (there should never be unless someone is messing about, as it's supposed
2403 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2404 if the connection is using TLS or if the remote IP is the same as the
2405 local IP, and the "valid-client-cert option" if a client certificate has
2406 been verified.

PH
2437
2438PH/30 Exim was sometimes attempting to deliver messages that had suffered
2439 address errors (4xx response to RCPT) over the same connection as other
2440 messages routed to the same hosts. Such deliveries are always "forced",
2441 so retry times are not inspected. This resulted in far too many retries
2442 for the affected addresses. The effect occurred only when there were more
2443 hosts than the hosts_max_try setting in the smtp transport when it had
2444 the 4xx errors. Those hosts that it had tried were not added to the list
2445 of hosts for which the message was waiting, so if all were tried, there
2446 was no problem. Two fixes have been applied:
2447
2448 (i) If there are any address or message errors in an SMTP delivery, none
2449 of the hosts (tried or untried) are now added to the list of hosts
2450 for which the message is waiting, so the message should not be a
2451 candidate for sending over the same connection that was used for a
2452 successful delivery of some other message. This seems entirely
2453 reasonable: after all the message is NOT "waiting for some host".
2454 This is so "obvious" that I'm not sure why it wasn't done
2455 previously. Hope I haven't missed anything, but it can't do any
2456 harm, as the worst effect is to miss an optimization.
2457
2458 (ii) If, despite (i), such a delivery is accidentally attempted, the
2459 routing retry time is respected, so at least it doesn't keep
2460 hammering the server.

2475PH/35 The error "getsockname() failed: connection reset by peer" was being
2476 written to the panic log as well as the main log, but it isn't really

2478 removed the panic log writing for the ECONNRESET error when getsockname()
2479 fails.
2480
48c7f9e2
PH
2481PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2482 runs only) independently of the message's sender address. This meant
2483 that, if the 4xx error was in fact related to the sender, a different
2484 message to the same recipient with a different sender could confuse
4c04137d 2485 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2486 server, but other circumstances could also provoke similar problems.
2487 I have changed the default so that the retry time for these errors is now
2488 based a combination of the sender and recipient addresses. This change
2489 can be overridden by setting address_retry_include_sender=false in the
2490 smtp transport.

2758PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2760 Unfortunately, if there is a major crisis, such as a disk failure,
2761 tcp-wrappers gives "deny", whereas what one would like would be some
2762 kind of temporary error. A kludge has been added to help with this.
2763 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2764 554 error is used if errno is still zero or contains ENOENT (which occurs
2765 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2766 451 error is used.

2802PH/01 The code for finding all the local interface addresses on a FreeBSD
2803 system running IPv6 was broken. This may well have applied to all BSD
2804 systems, as well as to others that have similar system calls. The broken
2805 code found IPv4 interfaces correctly, but gave incorrect values for the
2806 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2807 that it would not match correctly against @[] and not recognize the IPv6
2808 addresses as local.

2851 autoreply, Exim could try to deliver to a non-existent relative file

2887 Instead, it always explicitly searches for A/AAAA records. This avoids
2888 major problems that occur when a DNS server includes only records of one
2889 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2890 fixed another bug: if SRV records were looked up and the corresponding
2891 address records were *not* found in the additional section, the port
2892 values from the SRV records were lost.

PH
2902PH/19 When calculating a retry time, Exim used to measure the "time since
2903 failure" by looking at the "first failed" field in the retry record. Now
2904 it does not use this if it is later than than the arrival time of the
2905 message. Instead it uses the arrival time. This makes for better
2906 behaviour in cases where some deliveries succeed, thus re-setting the
2907 "first failed" field. An example is a quota failure for a huge message
2908 when small messages continue to be delivered. Without this change, the
2909 "time since failure" will always be short, possible causing more frequent
2910 delivery attempts for the huge message than are intended.

3007PH/42 The content-scanning code uses fopen() to create files in which to put
3008 message data. Previously it was not paying any attention to the mode of
3009 the files. Exim runs with umask(0) because the rest of the code creates
3010 files with open(), and sets the required mode explicitly. Thus, these
3011 files were ending up world-writeable. This was not a big issue, because,
3012 being within the spool directory, they were not world-accessible. I have
3013 created a function called modefopen, which takes an additional mode
3014 argument. It sets umask(777), creates the file, chmods it to the required
3015 mode, then resets the umask. All the relevant calls to fopen() in the

3056 was used in LMTP mode. This meant that they could be retried too
3057 frequently, and not timed out correctly.
3058
3059 (ii) Exim was setting the flag that allows error details to be returned
3060 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3061 recipients that were returned after the DATA command.
3062
3063PH/53 This is related to PH/52, but is more general: for any failing address,
3064 when detailed error information was permitted to be returned to the

3106 verification continued, and the new address failed or deferred after

3123PH/68 The bounce_return_message and bounce_return_body options were not being
3124 honoured for bounces generated during the reception of non-SMTP messages.
3125 In particular, this applied to messages rejected by the ACL. This bug has
3126 been fixed. However, if bounce_return_message is true and bounce_return_
3127 body is false, the headers that are returned for a non-SMTP message
3128 include only those that have been read before the error was detected.

3137PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3138 function verify_get_ident() calls ip_connect() to connect a socket, but
3139 if the "connect()" function timed out, ip_connect() used to close the
3140 socket. However, verify_get_ident() also closes the socket later, and in
3141 between Exim writes to the log, which may get opened at this point. When
3142 the socket was closed in ip_connect(), the log could get the same file
3143 descriptor number as the socket. This naturally causes chaos. The fix is
3144 not to close the socket in ip_connect(); the socket should be closed by
3145 the function that creates it. There was only one place in the code where
3146 this was missing, in the iplookup router, which I don't think anybody now
3147 uses, but I've fixed it anyway.

3161
3162 (2) Add control=submission to the relay_from_hosts and authenticated
3163 clients checks, on the grounds that messages accepted by these
3164 statements are most likely to be submissions.

3166PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3167
3168 (1) Generate an error if the third argument for the ${prvs expansion is
3169 not a single digit.
3170
3171 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3172 string.
3173
3174 (3) Reset the variables that are obtained from the first argument of
3175 ${prvscheck and used in the second argument before leaving the code,
3176 because their memory is reclaimed, so using them afterwards may do
3177 silly things.
3178
3179 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3180 one (it's much easier than Tom thought :-).
3181
3182 (5) Because of (4), we can now allow for the use of $prvscheck_result
3183 inside the third argument.

3192PH/05 When a filter generated an autoreply, the entire To: header line was
3193 quoted in the delivery log line, like this:
3194
3195 => >A.N.Other <ano@some.domain> <original@ddress> ...
3196
3197 This has been changed so that it extracts the operative address. There
3198 may be more than one such address. If so, they are comma-separated, like
3199 this:
3200
3201 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
3203PH/06 When a client host used a correct literal IP address in a HELO or EHLO
3204 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3205 not being looked up in the rDNS to get a host name, Exim was showing the
3206 IP address twice in Received: lines, even though the IP addresses were
3207 identical. For example:
3208
3209 Received: from [1.2.3.4] (helo=[1.2.3.4])
3210
3211 However, if the real host name was known, it was omitting the HELO data
3212 if it matched the actual IP address. This has been tidied up so that it
3213 doesn't show the same IP address twice.

3215PH/07 When both +timestamp and +memory debugging was on, the value given by

3239PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

3242 Auto-submitted: auto-generated
3243
3244 in the messages that it generates (bounce messages and others, such as
4c04137d 3245 warnings). In the case of bounce messages for non-SMTP messages, there was
456682f5
PH
3246 also a typo: it was using "Auto_submitted" (underscore instead of
3247 hyphen). Since every message generated by Exim is necessarily in response
3248 to another message, thes have all been changed to:
3249
3250 Auto-Submitted: auto-replied
3251
3252 in accordance with these statements in the RFC:
3253
3254 The auto-replied keyword:
3255
3256 - SHOULD be used on messages sent in direct response to another
3257 message by an automatic process,
3258
3259 - MUST NOT be used on manually-generated messages,
3260
3261 - MAY be used on Delivery Status Notifications (DSNs) and Message
3262 Disposition Notifications (MDNs),
3263
3264 - MUST NOT be used on messages generated by automatic or periodic
3265 processes, except for messages which are automatic responses to
3266 other messages.
