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.
15

PP
16PP/01 Allow PKG_CONFIG_PATH to be set in Local/Makefile and use it correctly
17 during configuration. Wildcards are allowed and expanded.

JH
19JH/02 Rework error string handling in DKIM to pass more info back to callers.
20 This permits better logging.
21
875512a3
JH
22JH/03 Rework the transport continued-connection mechanism: when TLS is active,
23 do not close it down and have the child transport start it up again on
24 the passed-on TCP connection. Instead, proxy the child (and any
25 subsequent ones) for TLS via a unix-domain socket channel. Logging is
26 affected: the continued delivery log lines do not have any DNSSEC, TLS
27 cipher, Certificate or OCSP information.
28

29JH/04 Shorten the log line for daemon startup by collapsing adjacent sets of
30 identical IP addresses on different listening ports. Will also affect
31 "exiwhat" output.

9427e879 37JH/01 Bug 1922: Support IDNA2008. This has slightly different conversion rules
4c04137d 38 than -2003 did; needs libidn2 in addition to libidn.

45JH/03 Bug 2003: fix Proxy Protocol v2 handling: the address size field was
46 missing a wire-to-host endian conversion.

JH
48JH/04 Bug 2004: fix CHUNKING in non-PIPELINEING mode. Chunk data following
49 close after a BDAT command line could be taken as a following command,
50 giving a synch failure. Fix by only checking for synch immediately
51 before acknowledging the chunk.
52

53PP/02 GitHub PR 52: many spelling fixes, which include fixing parsing of
54 no_require_dnssec option and creation of _HAVE_TRANSPORT_APPEND_MAILDIR
55 macro. Patches provided by Josh Soref.
56
bd8fbe36
JH
57JH/05 Have the EHLO response advertise VRFY, if there is a vrfy ACL defined.
58 Previously we did not; the RFC seems ambiguous and VRFY is not listed
59 by IANA as a service extension. However, John Klensin suggests that we
60 should.
61
62JH/06 Bug 2017: Fix DKIM verification in -bh test mode. The data feed into
b895f4b2
JH
63 the dkim code may be unix-mode line endings rather than smtp wire-format
64 CRLF, so prepend a CR to any bare LF.
fd047340 65
bd8fbe36 66JH/07 Rationalise the coding for callout smtp conversations and transport ones.
902fbd69
JH
67 As a side-benfit, callouts can now use PIPELINING hence fewer round-trips.
68
bd8fbe36
JH
69JH/08 Bug 2016: Fix DKIM verification vs. CHUNKING. Any BDAT commands after
70 the first were themselves being wrongly included in the feed into dkim
71 processing; with most chunk sizes in use this resulted in an incorrect
72 body hash calculated value.
73
eea19017
JH
74JH/09 Bug 2014: permit inclusion of a DKIM-Signature header in a received
75 DKIM signature block, for verification. Although advised against by
76 standards it is specifically not ruled illegal.
77
44e6651b
JH
78JH/10 Bug 2025: Fix reception of (quoted) local-parts with embedded spaces.
79
80JH/11 Bug 2029: Fix crash in DKIM verification when a message signature block is
81 missing a body hash (the bh= tag).
82
83JH/12 Bug 2018: Re-order Proxy Protocol startup versus TLS-on-connect startup.
84 It seems that HAProxy sends the Proxy Protocol information in clear and
85 only then does a TLS startup, so do the same.
86
87JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
88 TCP connections (such as for Spamd) unless the daemon successfully set
89 Fast Open mode on its listening sockets. This fixes breakage seen on
90 too-old kernels or those not configured for Fast Open, at the cost of
91 requiring both directions being enabled for TFO, and TFO never being used
92 by non-daemon-related Exim processes.
93
94JH/14 Bug 2000: Reject messages recieved with CHUNKING but with malformed line
95 endings, at least on the first header line. Try to canonify any that get
96 past that check, despite the cost.
97
b6040544
JH
98JH/15 Angle-bracket nesting (an error inserted by broken sendmails) levels are
99 now limited to an arbitrary five deep, while parsing addresses with the
100 strip_excess_angle_brackets option enabled.

102PP/03 Bug 2018: For Proxy Protocol and TLS-on-connect, do not over-read and
103 instead leave the unprompted TLS handshake in socket buffer for the
104 TLS library to consume.

109
90341c71
JH
110JH/16 Drop variables when they go out of scope. Memory management drops a whole
111 region in one operation, for speed, and this leaves assigned pointers
112 dangling. Add checks run only under the testsuite which checks all
113 variables at a store-reset and panics on a dangling pointer; add code
114 explicitly nulling out all the variables discovered. Fixes one known
115 bug: a transport crash, where a dangling pointer for $sending_ip_address
116 originally assigned in a verify callout, is re-used.

9094b84b
JH
146JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
147 supports it and a size is available (ie. the sending peer gave us one).
8d042305 148
03d5892b
JH
149JH/02 The obsolete acl condition "demime" is removed (finally, after ten
150 years of being deprecated). The replacements are the ACLs
151 acl_smtp_mime and acl_not_smtp_mime.
152
4b0fe319
JH
153JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
154 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
155 or even an in-clear connection were permitted. Now, if the host lookup
156 was dnssec and dane was requested then the host is only used if the
157 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
158 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
159 if one fails this test.
160 This means that a poorly-configured remote DNS will make it incommunicado;
161 but it protects against a DNS-interception attack on it.

164 non-noisy when a race steals the message being considered.

181 certificate).
182
98c82a3d
JH
183JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
184 a cutthrough deliver is pending, as we always want to make a connection.
185 This also avoids re-routing the message when later placing the cutthrough
186 connection after a verify cache hit.
187 Do not update it with the verify result either.
188
189JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
190 when routing results in more than one destination address.
191
ae8386f0
JH
192JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
193 signing (which inhibits the cutthrough capability). Previously only
194 the presence of an option was tested; now an expansion evaluating as
195 empty is permissible (obviously it should depend only on data available
196 when the cutthrough connection is made).

376JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
377 in transport context, after the attempt, and per-recipient. The latter type
378 is per host attempted. The event data is the error message, and the errno
379 information encodes the lookup type (A vs. MX) used for the (first) host,
4c04137d 380 and the trailing two digits of the smtp 4xx response.

975TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
976
977 When a queue runner is handling a message, Exim first routes the
978 recipient addresses, during which it prunes them based on the retry
979 hints database. After that it attempts to deliver the message to
980 any remaining recipients. It then updates the hints database using
981 the retry rules.
982
983 So if a recipient address works intermittently, it can get repeatedly
984 deferred at routing time. The retry hints record remains fresh so the
985 address never reaches the final cutoff time.
986
987 This is a fairly common occurrence when a user is bumping up against
988 their storage quota. Exim had some logic in its local delivery code
989 to deal with this. However it did not apply to per-recipient defers
990 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
991
1ddeb334
TF
992 This change adds a proper retry rule check during routing so that the
993 final cutoff time is checked against the message's age. We only do
994 this check if there is an address retry record and there is not a
995 domain retry record; this implies that previous attempts to handle
996 the address had the retry_use_local_parts option turned on. We use
997 this as an approximation for the destination being like a local
998 delivery, as in LMTP.
67bd1ab3
TF
999
1000 I suspect this new check makes the old local delivery cutoff check
1001 redundant, but I have not verified this so I left the code in place.

1010 the header to contain my full name, whereas it should have added
1011 a Resent-Sender: header. It erroneously treats any prefix of the
1012 username as equal to the username.

1036 Server implementation by Todd Lyons, client by JH.
1037 Only enabled when compiled with EXPERIMENTAL_PRDR. A new

1039 advertises the facility. If the client requests PRDR a new

1041 the body content is received and before the acl_smtp_data ACL.

TF
1323TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1324 lock up or crash if it happened to be inside a call to libc when it
1325 got a SIGUSR1 from exiwhat.
1326
1327 The SIGUSR1 handler appends the current process status to the process
1328 log which is later printed by exiwhat. It used to use the general
1329 purpose logging code to do this, but several functions it calls are
1330 not safe for signals.
1331
1332 The new output code in the SIGUSR1 handler is specific to the process
1333 log, and simple enough that it's easy to inspect for signal safety.
1334 Removing some special cases also simplifies the general logging code.
1335 Removing the spurious timestamps from the process log simplifies
1336 exiwhat.
1337
c99ce5c9
TF
1338TF/04 Improved ratelimit ACL condition.
1339
1340 The /noupdate option has been deprecated in favour of /readonly which
1341 has clearer semantics. The /leaky, /strict, and /readonly update modes
1342 are mutually exclusive. The update mode is no longer included in the
1343 database key; it just determines when the database is updated. (This
4c04137d 1344 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1345
1346 Exim now checks that the per_* options are used with an update mode that
1347 makes sense for the current ACL. For example, when Exim is processing a
1348 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1349 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1350 must specify per_mail/readonly. If you omit the update mode it defaults to
1351 /leaky where that makes sense (as before) or /readonly where required.
1352
1353 The /noupdate option is now undocumented but still supported for
1354 backwards compatibility. It is equivalent to /readonly except that in
1355 ACLs where /readonly is required you may specify /leaky/noupdate or
1356 /strict/noupdate which are treated the same as /readonly.
1357
1358 A useful new feature is the /count= option. This is a generalization
1359 of the per_byte option, so that you can measure the throughput of other
1360 aggregate values. For example, the per_byte option is now equivalent
1361 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1362
1363 The per_rcpt option has been generalized using the /count= mechanism
1364 (though it's more complicated than the per_byte equivalence). When it is
1365 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1366 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1367 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1368 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1369 Note that using per_rcpt with a non-readonly update mode in more than
1370 one ACL will cause the recipients to be double-counted. (The per_mail
1371 and per_byte options don't have this problem.)
1372
1373 The handling of very low rates has changed slightly. If the computed rate
1374 is less than the event's count (usually one) then this event is the first
1375 after a long gap. In this case the rate is set to the same as this event's
1376 count, so that the first message of a spam run is counted properly.
1377
1378 The major new feature is a mechanism for counting the rate of unique
1379 events. The new per_addr option counts the number of different
1380 recipients that someone has sent messages to in the last time period. It
1381 behaves like per_rcpt if all the recipient addresses are different, but
1382 duplicate recipient addresses do not increase the measured rate. Like
1383 the /count= option this is a general mechanism, so the per_addr option
1384 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1385 example, measure the rate that a client uses different sender addresses
1386 with the options per_mail/unique=$sender_address. There are further
1387 details in the main documentation.

1937 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1938 were called 'true' and it seems that C99 defines that as a reserved
1939 keyword to be used with 'bool' variable types. That means you could
1940 not include C99-style headers which use bools without triggering
1941 build errors in sieve.c.

1960
6a3bceb1
PH
1961PH/02 When an IPv6 address is converted to a string for single-key lookup
1962 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1963 dots are used instead of colons so that keys in lsearch files need not
1964 contain colons. This was done some time before quoting was made available
1965 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1966 (notated using the quote facility) so as to distinguish them from IPv4
1967 keys. This meant that lookups for IP addresses in host lists did not work
1968 for iplsearch lookups.
1969
1970 This has been fixed by arranging for IPv6 addresses to be expressed with
1971 colons if the lookup type is iplsearch. This is not incompatible, because
1972 previously such lookups could never work.
1973
4c04137d 1974 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
1975 ordinary lsearch keys. However, making the change in all cases is
1976 incompatible and would probably break a number of configurations.

1981MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1982 conversion specification without a maximum field width, thereby enabling
1983 a rogue spamd server to cause a buffer overflow. While nobody in their
1984 right mind would setup Exim to query an untrusted spamd server, an
1985 attacker that gains access to a server running spamd could potentially
1986 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1991MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1992 a directory entry by the name of the lookup key. Previously, if a
1993 symlink pointed to a non-existing file or a file in a directory that
1994 Exim lacked permissions to read, a lookup for a key matching that

2179PH/29 SMTP synchronization checks are implemented when a command is read -
2180 there is a check that no more input is waiting when there shouldn't be

2182 some time before the response is written. In this time, more input might
2183 arrive, invalidly. So now there are extra checks after an ACL has run for
2184 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2185 pipelining has not been advertised.

2259 the response to the final '.' that terminates a message, but only in the
2260 case where the client has not sent further data following the '.'
2261 (unfortunately, this is allowed). However, in many cases there won't be
2262 any further data because there won't be any more messages to send. A call
2263 to select() can be used: if it shows that the input is "ready", there is
2264 either input waiting, or the socket has been closed. An attempt to read
2265 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2266 would have sent an OK response which the client would never have see.

2278 fixed by 4.65/MH/01 (is this a record?) are fixed:
2279
2280 (i) An empty string was always treated as zero by the numeric comparison
2281 operators. This behaviour has been restored.
2282
2283 (ii) It is documented that the numeric comparison operators always treat
2284 their arguments as decimal numbers. This was broken in that numbers
2285 starting with 0 were being interpreted as octal.
2286
2287 While fixing these problems I realized that there was another issue that
2288 hadn't been noticed. Values of message_size_limit (both the global option
2289 and the transport option) were treated as octal if they started with 0.
2290 The documentation was vague. These values are now always treated as
2291 decimal, and I will make that clear in the documentation.

2322TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing

2325
2326TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
2327 in the DK code in transports.c. sendfile() is not really portable,

2333 in the field name.

PH
2335PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2336 callout verification, Exim cached a "reject" for the entire domain. This
2337 is correct for most verifications, but it is not correct for a recipient
2338 verification with use_sender or use_postmaster set, because in that case
2339 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2340 case of MAIL FROM:<> rejection from other early rejections (e.g.
2341 rejection of HELO). When verifying a recipient using a non-null MAIL
2342 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2343 Whatever the result of the callout, the value of the domain cache is
2344 left unchanged (for any other kind of callout, getting as far as trying
2345 RCPT means that the domain itself is ok).

2379PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2381 probably the interface on which it is arriving) and not to the outgoing
2382 callout (which could be using a different interface). This has been
2383 changed to use the value of the helo_data option from the smtp transport
2384 instead - this is what is used when a message is actually being sent. If
2385 there is no remote transport (possible with a router that sets up host
2386 addresses), $smtp_active_hostname is used.

7befa435 2389 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2390 (a) The code assumed that strncpy() returns a negative number on buffer
2391 overflow, which isn't the case. Replaced with Exim's string_format()
2392 function.
2393 (b) There were several signed/unsigned issues. I just did the minimum
2394 hacking in of casts. There is scope for a larger refactoring.
2395 (c) The code used strcasecmp() which is not a standard C function.
2396 Replaced with Exim's strcmpic() function.
2397 (d) The code set only $1; it now sets $auth1 as well.
2398 (e) A simple test gave the error "authentication client didn't specify
2399 service in request". It would seem that Dovecot has changed its
2400 interface. Fortunately there's a specification; I followed it and
2401 changed what the client sends and it appears to be working now.

2406PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2407 address A is aliased to B and C, where B exists and C does not. Without
2408 -v the output is "A verified" because verification stops after a
2409 successful redirection if more than one address is generated. However,
2410 with -v the child addresses are also verified. Exim was outputting "A
2411 failed to verify" and then showing the successful verification for C,
2412 with its parentage. It now outputs "B failed to verify", showing B's
2413 parentage before showing the successful verification of C.

2418
322050c2
PH
2419PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2420 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2421 they consult the DNS. I had assumed they would set it the way they
2422 wanted; and indeed my experiments on Linux seem to show that in some
2423 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2424 To be on the safe side, however, I have now made the interface to
2425 host_find_byname() similar to host_find_bydns(), with an argument
2426 containing the DNS resolver options. The host_find_byname() function now
2427 sets these options at its start, just as host_find_bydns() does. The smtp
2428 transport options dns_qualify_single and dns_search_parents are passed to
2429 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2430 of host_find_byname() use the default settings of RES_DEFNAMES
2431 (qualify_single) but not RES_DNSRCH (search_parents).

PH
2433PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2434 spool_read_header() do less string testing, by means of a preliminary
2435 switch on the second character of optional "-foo" lines. (This is
2436 overdue, caused by the large number of possibilities that now exist.
2437 Originally there were few.) While I was there, I also converted the
2438 str(n)cmp tests so they don't re-test the leading "-" and the first
2439 character, in the hope this might squeeze out yet more improvement.

PH
2441PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2442 flag allowing group syntax was set by the header_syntax check but not
2443 turned off, possible causing trouble later; (2) The flag was not being
2444 set at all for the header_verify test, causing "group"-style headers to
2445 be rejected. I have now set it in this case, and also caused header_
2446 verify to ignore an empty address taken from a group. While doing this, I
2447 came across some other cases where the code for allowing group syntax
2448 while scanning a header line wasn't quite right (mostly, not resetting
2449 the flag correctly in the right place). These bugs could have caused
2450 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
2452PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2453 with the "reply" argument non-NULL. The code, however (which originally
2454 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2455 but it didn't always do it. This confused somebody who was copying the
2456 code for some other use. I have removed all the tests.

PH
2458PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2459 feature that was used to support insecure browsers during the U.S. crypto
2460 embargo. It requires special client support, and Exim is probably the
2461 only MTA that supported it -- and would never use it because real RSA is
2462 always available. This code has been removed, because it had the bad
2463 effect of slowing Exim down by computing (never used) parameters for the
2464 RSA_EXPORT functionality.

PH
2466PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2467 authenticator to fail if there's a tab character in the incoming data
2468 (there should never be unless someone is messing about, as it's supposed
2469 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2470 if the connection is using TLS or if the remote IP is the same as the
2471 local IP, and the "valid-client-cert option" if a client certificate has
2472 been verified.

2503
2504PH/30 Exim was sometimes attempting to deliver messages that had suffered
2505 address errors (4xx response to RCPT) over the same connection as other
2506 messages routed to the same hosts. Such deliveries are always "forced",
2507 so retry times are not inspected. This resulted in far too many retries
2508 for the affected addresses. The effect occurred only when there were more
2509 hosts than the hosts_max_try setting in the smtp transport when it had
2510 the 4xx errors. Those hosts that it had tried were not added to the list
2511 of hosts for which the message was waiting, so if all were tried, there
2512 was no problem. Two fixes have been applied:
2513
2514 (i) If there are any address or message errors in an SMTP delivery, none
2515 of the hosts (tried or untried) are now added to the list of hosts
2516 for which the message is waiting, so the message should not be a
2517 candidate for sending over the same connection that was used for a
2518 successful delivery of some other message. This seems entirely
2519 reasonable: after all the message is NOT "waiting for some host".
2520 This is so "obvious" that I'm not sure why it wasn't done
2521 previously. Hope I haven't missed anything, but it can't do any
2522 harm, as the worst effect is to miss an optimization.
2523
2524 (ii) If, despite (i), such a delivery is accidentally attempted, the
2525 routing retry time is respected, so at least it doesn't keep
2526 hammering the server.

2542 written to the panic log as well as the main log, but it isn't really

2544 removed the panic log writing for the ECONNRESET error when getsockname()
2545 fails.

48c7f9e2
PH
2547PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2548 runs only) independently of the message's sender address. This meant
2549 that, if the 4xx error was in fact related to the sender, a different
2550 message to the same recipient with a different sender could confuse
4c04137d 2551 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2552 server, but other circumstances could also provoke similar problems.
2553 I have changed the default so that the retry time for these errors is now
2554 based a combination of the sender and recipient addresses. This change
2555 can be overridden by setting address_retry_include_sender=false in the
2556 smtp transport.

2824PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2826 Unfortunately, if there is a major crisis, such as a disk failure,
2827 tcp-wrappers gives "deny", whereas what one would like would be some
2828 kind of temporary error. A kludge has been added to help with this.
2829 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2830 554 error is used if errno is still zero or contains ENOENT (which occurs
2831 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2832 451 error is used.

2871 code found IPv4 interfaces correctly, but gave incorrect values for the
2872 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2873 that it would not match correctly against @[] and not recognize the IPv6
2874 addresses as local.

2917 autoreply, Exim could try to deliver to a non-existent relative file

2953 Instead, it always explicitly searches for A/AAAA records. This avoids
2954 major problems that occur when a DNS server includes only records of one
2955 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2956 fixed another bug: if SRV records were looked up and the corresponding
2957 address records were *not* found in the additional section, the port
2958 values from the SRV records were lost.

2960PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2968PH/19 When calculating a retry time, Exim used to measure the "time since
2969 failure" by looking at the "first failed" field in the retry record. Now
2970 it does not use this if it is later than than the arrival time of the
2971 message. Instead it uses the arrival time. This makes for better
2972 behaviour in cases where some deliveries succeed, thus re-setting the
2973 "first failed" field. An example is a quota failure for a huge message
2974 when small messages continue to be delivered. Without this change, the
2975 "time since failure" will always be short, possible causing more frequent
2976 delivery attempts for the huge message than are intended.

3076 files with open(), and sets the required mode explicitly. Thus, these
3077 files were ending up world-writeable. This was not a big issue, because,
3078 being within the spool directory, they were not world-accessible. I have
3079 created a function called modefopen, which takes an additional mode
3080 argument. It sets umask(777), creates the file, chmods it to the required
3081 mode, then resets the umask. All the relevant calls to fopen() in the
3082 content scanning code have been changed to use this function.

3090PH/45 When the plaintext authenticator is running as a client, the server's
3091 challenges are checked to ensure they are valid base64 strings. By
3092 default, the authentication attempt is cancelled if an invalid string is
3093 received. Setting client_ignore_invalid_base64 true ignores these errors.
3094 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
3095 they are received. Thus, the responses can be made to depend on the
3096 challenges. If an invalid string is ignored, an empty string is placed in
3097 the variable.

3108PH/50 When an Exim quota was set without a file count quota, and mailbox_size
3109 was also set, the appendfile transport was unnecessarily scanning a
3110 directory of message files (e.g. for maildir delivery) to find the count
3111 of files (along with the size), even though it did not need this
3112 information. It now does the scan only if it needs to find either the
3113 size of the count of files.

3117PH/52 Two bugs concerned with error handling when the smtp transport is
3118 used in LMTP mode:
3119
3120 (i) Exim was not creating retry information for temporary errors given
3121 for individual recipients after the DATA command when the smtp transport
3122 was used in LMTP mode. This meant that they could be retried too
3123 frequently, and not timed out correctly.
3124
3125 (ii) Exim was setting the flag that allows error details to be returned
3126 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3127 recipients that were returned after the DATA command.
3128
3129PH/53 This is related to PH/52, but is more general: for any failing address,
3130 when detailed error information was permitted to be returned to the
3131 sender, but the error was temporary, then after the final timeout, only
3132 "retry timeout exceeded" was returned. Now it returns the full error as
3133 well as "retry timeout exceeded".

3189PH/68 The bounce_return_message and bounce_return_body options were not being
3190 honoured for bounces generated during the reception of non-SMTP messages.
3191 In particular, this applied to messages rejected by the ACL. This bug has
3192 been fixed. However, if bounce_return_message is true and bounce_return_
3193 body is false, the headers that are returned for a non-SMTP message
3194 include only those that have been read before the error was detected.

PH
3203PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3204 function verify_get_ident() calls ip_connect() to connect a socket, but
3205 if the "connect()" function timed out, ip_connect() used to close the
3206 socket. However, verify_get_ident() also closes the socket later, and in
3207 between Exim writes to the log, which may get opened at this point. When
3208 the socket was closed in ip_connect(), the log could get the same file
3209 descriptor number as the socket. This naturally causes chaos. The fix is
3210 not to close the socket in ip_connect(); the socket should be closed by
3211 the function that creates it. There was only one place in the code where
3212 this was missing, in the iplookup router, which I don't think anybody now
3213 uses, but I've fixed it anyway.

3232PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3233
3234 (1) Generate an error if the third argument for the ${prvs expansion is
3235 not a single digit.
3236
3237 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3238 string.
3239
3240 (3) Reset the variables that are obtained from the first argument of
3241 ${prvscheck and used in the second argument before leaving the code,
3242 because their memory is reclaimed, so using them afterwards may do
3243 silly things.
3244
3245 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3246 one (it's much easier than Tom thought :-).
3247
3248 (5) Because of (4), we can now allow for the use of $prvscheck_result
3249 inside the third argument.

3262
3263 This has been changed so that it extracts the operative address. There
3264 may be more than one such address. If so, they are comma-separated, like

3269PH/06 When a client host used a correct literal IP address in a HELO or EHLO
3270 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3271 not being looked up in the rDNS to get a host name, Exim was showing the
3272 IP address twice in Received: lines, even though the IP addresses were
3273 identical. For example:
3274
3275 Received: from [1.2.3.4] (helo=[1.2.3.4])
3276
3277 However, if the real host name was known, it was omitting the HELO data
3278 if it matched the actual IP address. This has been tidied up so that it
3279 doesn't show the same IP address twice.
