8Exim version 4.90
9-----------------
10
11JH/01 Rework error string handling in TLS interface so that the caller in
12 more cases is responsible for logging. This permits library-sourced
13 string to be attached to addresses during delivery, and collapses
14 pairs of long lines into single ones.

9427e879 23JH/01 Bug 1922: Support IDNA2008. This has slightly different conversion rules
4c04137d 24 than -2003 did; needs libidn2 in addition to libidn.

34JH/04 Bug 2004: fix CHUNKING in non-PIPELINEING mode. Chunk data following
35 close after a BDAT command line could be taken as a following command,
36 giving a synch failure. Fix by only checking for synch immediately
37 before acknowledging the chunk.

39PP/02 GitHub PR 52: many spelling fixes, which include fixing parsing of

JH
43JH/05 Have the EHLO response advertise VRFY, if there is a vrfy ACL defined.
44 Previously we did not; the RFC seems ambiguous and VRFY is not listed
45 by IANA as a service extension. However, John Klensin suggests that we
46 should.
47
48JH/06 Bug 2017: Fix DKIM verification in -bh test mode. The data feed into
b895f4b2
JH
49 the dkim code may be unix-mode line endings rather than smtp wire-format
50 CRLF, so prepend a CR to any bare LF.
fd047340 51
bd8fbe36 52JH/07 Rationalise the coding for callout smtp conversations and transport ones.
902fbd69
JH
53 As a side-benfit, callouts can now use PIPELINING hence fewer round-trips.
54
bd8fbe36
JH
55JH/08 Bug 2016: Fix DKIM verification vs. CHUNKING. Any BDAT commands after
56 the first were themselves being wrongly included in the feed into dkim
57 processing; with most chunk sizes in use this resulted in an incorrect
58 body hash calculated value.
59
eea19017
JH
60JH/09 Bug 2014: permit inclusion of a DKIM-Signature header in a received
61 DKIM signature block, for verification. Although advised against by
62 standards it is specifically not ruled illegal.
63
44e6651b
JH
64JH/10 Bug 2025: Fix reception of (quoted) local-parts with embedded spaces.
65
66JH/11 Bug 2029: Fix crash in DKIM verification when a message signature block is
67 missing a body hash (the bh= tag).
68
69JH/12 Bug 2018: Re-order Proxy Protocol startup versus TLS-on-connect startup.
70 It seems that HAProxy sends the Proxy Protocol information in clear and
71 only then does a TLS startup, so do the same.
72
73JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
74 TCP connections (such as for Spamd) unless the daemon successfully set
75 Fast Open mode on its listening sockets. This fixes breakage seen on
76 too-old kernels or those not configured for Fast Open, at the cost of
77 requiring both directions being enabled for TFO, and TFO never being used
78 by non-daemon-related Exim processes.
79
80JH/14 Bug 2000: Reject messages recieved with CHUNKING but with malformed line
81 endings, at least on the first header line. Try to canonify any that get
82 past that check, despite the cost.
83
b6040544
JH
84JH/15 Angle-bracket nesting (an error inserted by broken sendmails) levels are
85 now limited to an arbitrary five deep, while parsing addresses with the
86 strip_excess_angle_brackets option enabled.

88PP/03 Bug 2018: For Proxy Protocol and TLS-on-connect, do not over-read and
89 instead leave the unprompted TLS handshake in socket buffer for the
90 TLS library to consume.

94PP/05 FreeBSD compat: handle that Ports no longer create /usr/bin/perl
95
90341c71
JH
96JH/16 Drop variables when they go out of scope. Memory management drops a whole
97 region in one operation, for speed, and this leaves assigned pointers
98 dangling. Add checks run only under the testsuite which checks all
99 variables at a store-reset and panics on a dangling pointer; add code
100 explicitly nulling out all the variables discovered. Fixes one known
101 bug: a transport crash, where a dangling pointer for $sending_ip_address
102 originally assigned in a verify callout, is re-used.

104PP/06 Drop '.' from @INC in various Perl scripts.
105
106PP/07 Switch FreeBSD iconv to always use the base-system libc functions.
107
108PP/08 Reduce a number of compilation warnings under clang; building with
109 CC=clang CFLAGS+=-Wno-dangling-else -Wno-logical-op-parentheses
110 should be warning-free.

128JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
129 supports it and a size is available (ie. the sending peer gave us one).
8d042305 130
03d5892b
JH
131JH/02 The obsolete acl condition "demime" is removed (finally, after ten
132 years of being deprecated). The replacements are the ACLs
133 acl_smtp_mime and acl_not_smtp_mime.
134
4b0fe319
JH
135JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
136 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
137 or even an in-clear connection were permitted. Now, if the host lookup
138 was dnssec and dane was requested then the host is only used if the
139 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
140 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
141 if one fails this test.
142 This means that a poorly-configured remote DNS will make it incommunicado;
143 but it protects against a DNS-interception attack on it.
144

JH
145JH/04 Bug 1810: make continued-use of an open smtp transport connection
146 non-noisy when a race steals the message being considered.

f59aaaaa 149 self-signed certificate for inbound TLS connections.

f42deca9 152 in rewrites and routers.

JH
154JH/07 Retire gnutls_require_mac et.al. These were nonfunctional since 4.80
155 and logged a warning sing 4.83; now they are a configuration file error.

163 certificate).
164
98c82a3d
JH
165JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
166 a cutthrough deliver is pending, as we always want to make a connection.
167 This also avoids re-routing the message when later placing the cutthrough
168 connection after a verify cache hit.
169 Do not update it with the verify result either.
170
171JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
172 when routing results in more than one destination address.
173
ae8386f0
JH
174JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
175 signing (which inhibits the cutthrough capability). Previously only
176 the presence of an option was tested; now an expansion evaluating as
177 empty is permissible (obviously it should depend only on data available
178 when the cutthrough connection is made).
179

180JH/14 Fix logging of errors under PIPELINING. Previously the log line giving
181 the relevant preceding SMTP command did not note the pipelining mode.

186JH/16 DANE: treat a TLSA lookup response having all non-TLSA RRs, the same
187 as one having no matching records. Previously we deferred the message

957TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
958
959 When a queue runner is handling a message, Exim first routes the
960 recipient addresses, during which it prunes them based on the retry
961 hints database. After that it attempts to deliver the message to
962 any remaining recipients. It then updates the hints database using
963 the retry rules.
964
965 So if a recipient address works intermittently, it can get repeatedly
966 deferred at routing time. The retry hints record remains fresh so the
967 address never reaches the final cutoff time.
968
969 This is a fairly common occurrence when a user is bumping up against
970 their storage quota. Exim had some logic in its local delivery code
971 to deal with this. However it did not apply to per-recipient defers
972 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
973
1ddeb334
TF
974 This change adds a proper retry rule check during routing so that the
975 final cutoff time is checked against the message's age. We only do
976 this check if there is an address retry record and there is not a
977 domain retry record; this implies that previous attempts to handle
978 the address had the retry_use_local_parts option turned on. We use
979 this as an approximation for the destination being like a local
980 delivery, as in LMTP.
67bd1ab3
TF
981
982 I suspect this new check makes the old local delivery cutoff check
983 redundant, but I have not verified this so I left the code in place.

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

1019 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
1020 config variable "prdr_enable" controls whether the server
1021 advertises the facility. If the client requests PRDR a new
1022 acl_data_smtp_prdr ACL is called once for each recipient, after
1023 the body content is received and before the acl_smtp_data ACL.

1305TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1306 lock up or crash if it happened to be inside a call to libc when it
1307 got a SIGUSR1 from exiwhat.
1308
1309 The SIGUSR1 handler appends the current process status to the process
1310 log which is later printed by exiwhat. It used to use the general
1311 purpose logging code to do this, but several functions it calls are
1312 not safe for signals.
1313
1314 The new output code in the SIGUSR1 handler is specific to the process
1315 log, and simple enough that it's easy to inspect for signal safety.
1316 Removing some special cases also simplifies the general logging code.
1317 Removing the spurious timestamps from the process log simplifies
1318 exiwhat.
1319
c99ce5c9
TF
1320TF/04 Improved ratelimit ACL condition.
1321
1322 The /noupdate option has been deprecated in favour of /readonly which
1323 has clearer semantics. The /leaky, /strict, and /readonly update modes
1324 are mutually exclusive. The update mode is no longer included in the
1325 database key; it just determines when the database is updated. (This
4c04137d 1326 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1327
1328 Exim now checks that the per_* options are used with an update mode that
1329 makes sense for the current ACL. For example, when Exim is processing a
1330 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1331 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1332 must specify per_mail/readonly. If you omit the update mode it defaults to
1333 /leaky where that makes sense (as before) or /readonly where required.
1334
1335 The /noupdate option is now undocumented but still supported for
1336 backwards compatibility. It is equivalent to /readonly except that in
1337 ACLs where /readonly is required you may specify /leaky/noupdate or
1338 /strict/noupdate which are treated the same as /readonly.
1339
1340 A useful new feature is the /count= option. This is a generalization
1341 of the per_byte option, so that you can measure the throughput of other
1342 aggregate values. For example, the per_byte option is now equivalent
1343 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1344
1345 The per_rcpt option has been generalized using the /count= mechanism
1346 (though it's more complicated than the per_byte equivalence). When it is
1347 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1348 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1349 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1350 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1351 Note that using per_rcpt with a non-readonly update mode in more than
1352 one ACL will cause the recipients to be double-counted. (The per_mail
1353 and per_byte options don't have this problem.)
1354
1355 The handling of very low rates has changed slightly. If the computed rate
1356 is less than the event's count (usually one) then this event is the first
1357 after a long gap. In this case the rate is set to the same as this event's
1358 count, so that the first message of a spam run is counted properly.
1359
1360 The major new feature is a mechanism for counting the rate of unique
1361 events. The new per_addr option counts the number of different
1362 recipients that someone has sent messages to in the last time period. It
1363 behaves like per_rcpt if all the recipient addresses are different, but
1364 duplicate recipient addresses do not increase the measured rate. Like
1365 the /count= option this is a general mechanism, so the per_addr option
1366 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1367 example, measure the rate that a client uses different sender addresses
1368 with the options per_mail/unique=$sender_address. There are further
1369 details in the main documentation.

1582 the case, and it resulted in successful deliveries going unlogged.

1941PH/01 Another patch from the Sieve maintainer.
1942
6a3bceb1
PH
1943PH/02 When an IPv6 address is converted to a string for single-key lookup
1944 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1945 dots are used instead of colons so that keys in lsearch files need not
1946 contain colons. This was done some time before quoting was made available
1947 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1948 (notated using the quote facility) so as to distinguish them from IPv4
1949 keys. This meant that lookups for IP addresses in host lists did not work
1950 for iplsearch lookups.
1951
1952 This has been fixed by arranging for IPv6 addresses to be expressed with
1953 colons if the lookup type is iplsearch. This is not incompatible, because
1954 previously such lookups could never work.
1955
4c04137d 1956 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
1957 ordinary lsearch keys. However, making the change in all cases is
1958 incompatible and would probably break a number of configurations.

1963MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1964 conversion specification without a maximum field width, thereby enabling
1965 a rogue spamd server to cause a buffer overflow. While nobody in their
1966 right mind would setup Exim to query an untrusted spamd server, an
1967 attacker that gains access to a server running spamd could potentially
1968 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1973MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1974 a directory entry by the name of the lookup key. Previously, if a
1975 symlink pointed to a non-existing file or a file in a directory that
1976 Exim lacked permissions to read, a lookup for a key matching that
1977 symlink would fail. Now it is enough that a matching directory entry

PH
2161PH/29 SMTP synchronization checks are implemented when a command is read -
2162 there is a check that no more input is waiting when there shouldn't be
2163 any. However, for some commands, a delay in an ACL can mean that it is
2164 some time before the response is written. In this time, more input might
2165 arrive, invalidly. So now there are extra checks after an ACL has run for
2166 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2167 pipelining has not been advertised.

PH
2179PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in

2182 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
2183 was a macro that became an assignment, so it seemed to work. This has
2184 changed to a proper function call with a void return, hence the compile
2185 error. Exim's code has been fixed.

PH
2241 the response to the final '.' that terminates a message, but only in the
2242 case where the client has not sent further data following the '.'
2243 (unfortunately, this is allowed). However, in many cases there won't be
2244 any further data because there won't be any more messages to send. A call
2245 to select() can be used: if it shows that the input is "ready", there is
2246 either input waiting, or the socket has been closed. An attempt to read
2247 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2248 would have sent an OK response which the client would never have see.

2259PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2260 fixed by 4.65/MH/01 (is this a record?) are fixed:
2261
2262 (i) An empty string was always treated as zero by the numeric comparison
2263 operators. This behaviour has been restored.
2264
2265 (ii) It is documented that the numeric comparison operators always treat
2266 their arguments as decimal numbers. This was broken in that numbers
2267 starting with 0 were being interpreted as octal.
2268
2269 While fixing these problems I realized that there was another issue that
2270 hadn't been noticed. Values of message_size_limit (both the global option
2271 and the transport option) were treated as octal if they started with 0.
2272 The documentation was vague. These values are now always treated as
2273 decimal, and I will make that clear in the documentation.

2318 callout verification, Exim cached a "reject" for the entire domain. This
2319 is correct for most verifications, but it is not correct for a recipient
2320 verification with use_sender or use_postmaster set, because in that case
2321 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2322 case of MAIL FROM:<> rejection from other early rejections (e.g.
2323 rejection of HELO). When verifying a recipient using a non-null MAIL
2324 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2325 Whatever the result of the callout, the value of the domain cache is
2326 left unchanged (for any other kind of callout, getting as far as trying
2327 RCPT means that the domain itself is ok).

2361PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2362 hostname. This is wrong, because it relates to the incoming message (and
2363 probably the interface on which it is arriving) and not to the outgoing
2364 callout (which could be using a different interface). This has been
2365 changed to use the value of the helo_data option from the smtp transport
2366 instead - this is what is used when a message is actually being sent. If
2367 there is no remote transport (possible with a router that sets up host
2368 addresses), $smtp_active_hostname is used.

7befa435 2371 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2372 (a) The code assumed that strncpy() returns a negative number on buffer
2373 overflow, which isn't the case. Replaced with Exim's string_format()
2374 function.
2375 (b) There were several signed/unsigned issues. I just did the minimum
2376 hacking in of casts. There is scope for a larger refactoring.
2377 (c) The code used strcasecmp() which is not a standard C function.
2378 Replaced with Exim's strcmpic() function.
2379 (d) The code set only $1; it now sets $auth1 as well.
2380 (e) A simple test gave the error "authentication client didn't specify
2381 service in request". It would seem that Dovecot has changed its
2382 interface. Fortunately there's a specification; I followed it and
2383 changed what the client sends and it appears to be working now.

2388PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2389 address A is aliased to B and C, where B exists and C does not. Without
2390 -v the output is "A verified" because verification stops after a
2391 successful redirection if more than one address is generated. However,
2392 with -v the child addresses are also verified. Exim was outputting "A
2393 failed to verify" and then showing the successful verification for C,
2394 with its parentage. It now outputs "B failed to verify", showing B's
2395 parentage before showing the successful verification of C.

2400
322050c2
PH
2401PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2402 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2403 they consult the DNS. I had assumed they would set it the way they
2404 wanted; and indeed my experiments on Linux seem to show that in some
2405 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2406 To be on the safe side, however, I have now made the interface to
2407 host_find_byname() similar to host_find_bydns(), with an argument
2408 containing the DNS resolver options. The host_find_byname() function now
2409 sets these options at its start, just as host_find_bydns() does. The smtp
2410 transport options dns_qualify_single and dns_search_parents are passed to
2411 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2412 of host_find_byname() use the default settings of RES_DEFNAMES
2413 (qualify_single) but not RES_DNSRCH (search_parents).

PH
2415PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2416 spool_read_header() do less string testing, by means of a preliminary
2417 switch on the second character of optional "-foo" lines. (This is
2418 overdue, caused by the large number of possibilities that now exist.
2419 Originally there were few.) While I was there, I also converted the
2420 str(n)cmp tests so they don't re-test the leading "-" and the first
2421 character, in the hope this might squeeze out yet more improvement.

PH
2423PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2424 flag allowing group syntax was set by the header_syntax check but not
2425 turned off, possible causing trouble later; (2) The flag was not being
2426 set at all for the header_verify test, causing "group"-style headers to
2427 be rejected. I have now set it in this case, and also caused header_
2428 verify to ignore an empty address taken from a group. While doing this, I
2429 came across some other cases where the code for allowing group syntax
2430 while scanning a header line wasn't quite right (mostly, not resetting
2431 the flag correctly in the right place). These bugs could have caused
2432 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
2434PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2435 with the "reply" argument non-NULL. The code, however (which originally
2436 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2437 but it didn't always do it. This confused somebody who was copying the
2438 code for some other use. I have removed all the tests.

PH
2440PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2441 feature that was used to support insecure browsers during the U.S. crypto
2442 embargo. It requires special client support, and Exim is probably the
2443 only MTA that supported it -- and would never use it because real RSA is
2444 always available. This code has been removed, because it had the bad
2445 effect of slowing Exim down by computing (never used) parameters for the
2446 RSA_EXPORT functionality.

PH
2448PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2449 authenticator to fail if there's a tab character in the incoming data
2450 (there should never be unless someone is messing about, as it's supposed
2451 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2452 if the connection is using TLS or if the remote IP is the same as the
2453 local IP, and the "valid-client-cert option" if a client certificate has
2454 been verified.

2485
2486PH/30 Exim was sometimes attempting to deliver messages that had suffered
2487 address errors (4xx response to RCPT) over the same connection as other
2488 messages routed to the same hosts. Such deliveries are always "forced",
2489 so retry times are not inspected. This resulted in far too many retries
2490 for the affected addresses. The effect occurred only when there were more
2491 hosts than the hosts_max_try setting in the smtp transport when it had
2492 the 4xx errors. Those hosts that it had tried were not added to the list
2493 of hosts for which the message was waiting, so if all were tried, there
2494 was no problem. Two fixes have been applied:
2495
2496 (i) If there are any address or message errors in an SMTP delivery, none
2497 of the hosts (tried or untried) are now added to the list of hosts
2498 for which the message is waiting, so the message should not be a
2499 candidate for sending over the same connection that was used for a
2500 successful delivery of some other message. This seems entirely
2501 reasonable: after all the message is NOT "waiting for some host".
2502 This is so "obvious" that I'm not sure why it wasn't done
2503 previously. Hope I haven't missed anything, but it can't do any
2504 harm, as the worst effect is to miss an optimization.
2505
2506 (ii) If, despite (i), such a delivery is accidentally attempted, the
2507 routing retry time is respected, so at least it doesn't keep
2508 hammering the server.

2523PH/35 The error "getsockname() failed: connection reset by peer" was being
2524 written to the panic log as well as the main log, but it isn't really

2526 removed the panic log writing for the ECONNRESET error when getsockname()
2527 fails.

48c7f9e2
PH
2529PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2530 runs only) independently of the message's sender address. This meant
2531 that, if the 4xx error was in fact related to the sender, a different
2532 message to the same recipient with a different sender could confuse
4c04137d 2533 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2534 server, but other circumstances could also provoke similar problems.
2535 I have changed the default so that the retry time for these errors is now
2536 based a combination of the sender and recipient addresses. This change
2537 can be overridden by setting address_retry_include_sender=false in the
2538 smtp transport.

2806PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2808 Unfortunately, if there is a major crisis, such as a disk failure,
2809 tcp-wrappers gives "deny", whereas what one would like would be some
2810 kind of temporary error. A kludge has been added to help with this.
2811 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2812 554 error is used if errno is still zero or contains ENOENT (which occurs
2813 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2814 451 error is used.

2850PH/01 The code for finding all the local interface addresses on a FreeBSD
2851 system running IPv6 was broken. This may well have applied to all BSD
2852 systems, as well as to others that have similar system calls. The broken
2853 code found IPv4 interfaces correctly, but gave incorrect values for the
2854 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2855 that it would not match correctly against @[] and not recognize the IPv6
2856 addresses as local.

2899 autoreply, Exim could try to deliver to a non-existent relative file

2934 additional section of a DNS packet that returns MX or SRV records.
2935 Instead, it always explicitly searches for A/AAAA records. This avoids
2936 major problems that occur when a DNS server includes only records of one
2937 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2938 fixed another bug: if SRV records were looked up and the corresponding
2939 address records were *not* found in the additional section, the port
2940 values from the SRV records were lost.

2942PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2950PH/19 When calculating a retry time, Exim used to measure the "time since
2951 failure" by looking at the "first failed" field in the retry record. Now
2952 it does not use this if it is later than than the arrival time of the
2953 message. Instead it uses the arrival time. This makes for better
2954 behaviour in cases where some deliveries succeed, thus re-setting the
2955 "first failed" field. An example is a quota failure for a huge message
2956 when small messages continue to be delivered. Without this change, the
2957 "time since failure" will always be short, possible causing more frequent
2958 delivery attempts for the huge message than are intended.

3055PH/42 The content-scanning code uses fopen() to create files in which to put

3058 files with open(), and sets the required mode explicitly. Thus, these
3059 files were ending up world-writeable. This was not a big issue, because,
3060 being within the spool directory, they were not world-accessible. I have
3061 created a function called modefopen, which takes an additional mode
3062 argument. It sets umask(777), creates the file, chmods it to the required
3063 mode, then resets the umask. All the relevant calls to fopen() in the

3090PH/50 When an Exim quota was set without a file count quota, and mailbox_size
3091 was also set, the appendfile transport was unnecessarily scanning a
3092 directory of message files (e.g. for maildir delivery) to find the count
3093 of files (along with the size), even though it did not need this
3094 information. It now does the scan only if it needs to find either the
3095 size of the count of files.

3099PH/52 Two bugs concerned with error handling when the smtp transport is
3100 used in LMTP mode:
3101
3102 (i) Exim was not creating retry information for temporary errors given
3103 for individual recipients after the DATA command when the smtp transport
3104 was used in LMTP mode. This meant that they could be retried too
3105 frequently, and not timed out correctly.
3106
3107 (ii) Exim was setting the flag that allows error details to be returned
3108 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3109 recipients that were returned after the DATA command.
3110
3111PH/53 This is related to PH/52, but is more general: for any failing address,
3112 when detailed error information was permitted to be returned to the
3113 sender, but the error was temporary, then after the final timeout, only
3114 "retry timeout exceeded" was returned. Now it returns the full error as
3115 well as "retry timeout exceeded".

3153PH/62 When verifying, if an address was redirected to one new address, so that
3154 verification continued, and the new address failed or deferred after
3155 having set something in $address_data, the value of $address_data was not
3156 passed back to the ACL. This was different to the case when no
3157 redirection occurred. The value is now passed back in both cases.

3159PH/63 Changed the macro HAVE_LOGIN_CAP (see PH/41 for this release above) to
3160 HAVE_SETCLASSRESOURCES because there are different APIs in use that all
3161 use login_cap.h, so on its own it isn't the distinguishing feature. The
3162 new name refers directly to the setclassresources() function.

PH
3171PH/68 The bounce_return_message and bounce_return_body options were not being
3172 honoured for bounces generated during the reception of non-SMTP messages.
3173 In particular, this applied to messages rejected by the ACL. This bug has
3174 been fixed. However, if bounce_return_message is true and bounce_return_
3175 body is false, the headers that are returned for a non-SMTP message
3176 include only those that have been read before the error was detected.
3177 (In the case of an ACL rejection, they have all been read.)

PH
3179PH/69 The HTML version of the specification is now built in a directory called
3180 spec_html instead of spec.html, because the latter looks like a path with
3181 a MIME-type, and this confuses some software.

3183PH/70 Catch two compiler warnings in sieve.c.

PH
3185PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3186 function verify_get_ident() calls ip_connect() to connect a socket, but
3187 if the "connect()" function timed out, ip_connect() used to close the
3188 socket. However, verify_get_ident() also closes the socket later, and in
3189 between Exim writes to the log, which may get opened at this point. When
3190 the socket was closed in ip_connect(), the log could get the same file
3191 descriptor number as the socket. This naturally causes chaos. The fix is
3192 not to close the socket in ip_connect(); the socket should be closed by
3193 the function that creates it. There was only one place in the code where
3194 this was missing, in the iplookup router, which I don't think anybody now
3195 uses, but I've fixed it anyway.

3197PH/72 Make dns_again_means_nonexist apply to lookups using gethostbyname() as

3205PH/01 Two changes to the default runtime configuration:
3206
3207 (1) Move the checks for relay_from_hosts and authenticated clients from
3208 after to before the (commented out) DNS black list checks.
3209
3210 (2) Add control=submission to the relay_from_hosts and authenticated
3211 clients checks, on the grounds that messages accepted by these
3212 statements are most likely to be submissions.

PH
3214PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3215
3216 (1) Generate an error if the third argument for the ${prvs expansion is
3217 not a single digit.
3218
3219 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3220 string.
3221
3222 (3) Reset the variables that are obtained from the first argument of
3223 ${prvscheck and used in the second argument before leaving the code,
3224 because their memory is reclaimed, so using them afterwards may do
3225 silly things.
3226
3227 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3228 one (it's much easier than Tom thought :-).
3229
3230 (5) Because of (4), we can now allow for the use of $prvscheck_result
3231 inside the third argument.

PH
3240PH/05 When a filter generated an autoreply, the entire To: header line was
3241 quoted in the delivery log line, like this:
3242
3243 => >A.N.Other <ano@some.domain> <original@ddress> ...
3244
3245 This has been changed so that it extracts the operative address. There
3246 may be more than one such address. If so, they are comma-separated, like
3247 this:
3248
3249 => >ano@some.domain,ona@other.domain <original@ddress> ...
3250
82c19f95
PH
3251PH/06 When a client host used a correct literal IP address in a HELO or EHLO
3252 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3253 not being looked up in the rDNS to get a host name, Exim was showing the
3254 IP address twice in Received: lines, even though the IP addresses were
3255 identical. For example:
3256
3257 Received: from [1.2.3.4] (helo=[1.2.3.4])
3258
3259 However, if the real host name was known, it was omitting the HELO data
3260 if it matched the actual IP address. This has been tidied up so that it
3261 doesn't show the same IP address twice.

PH
3263PH/07 When both +timestamp and +memory debugging was on, the value given by
3264 $tod_xxx expansions could be wrong, because the tod_stamp() function was
3265 called by the debug printing, thereby overwriting the timestamp buffer.
3266 Debugging no longer uses the tod_stamp() function when +timestamp is set.

PH
3268PH/08 When the original message was included in an autoreply transport, it
3269 always said "this is a copy of the message, including all the headers",
3270 even if body_only or headers_only was set. It now gives an appropriate
3271 message.

3278 o points to the current vacation draft in the documentation

3280
3281 and most important:
