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.

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.

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.

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.

902fbd69
JH
53 As a side-benfit, callouts can now use PIPELINING hence fewer round-trips.

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

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.

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

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

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.

122 supports it and a size is available (ie. the sending peer gave us one).

JH
124JH/02 The obsolete acl condition "demime" is removed (finally, after ten
125 years of being deprecated). The replacements are the ACLs
126 acl_smtp_mime and acl_not_smtp_mime.
127
4b0fe319
JH
128JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
129 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
130 or even an in-clear connection were permitted. Now, if the host lookup
131 was dnssec and dane was requested then the host is only used if the
132 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
133 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
134 if one fails this test.
135 This means that a poorly-configured remote DNS will make it incommunicado;
136 but it protects against a DNS-interception attack on it.

JH
158JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
159 a cutthrough deliver is pending, as we always want to make a connection.
160 This also avoids re-routing the message when later placing the cutthrough
161 connection after a verify cache hit.
162 Do not update it with the verify result either.
163
164JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
165 when routing results in more than one destination address.
166
ae8386f0
JH
167JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
168 signing (which inhibits the cutthrough capability). Previously only
169 the presence of an option was tested; now an expansion evaluating as
170 empty is permissible (obviously it should depend only on data available
171 when the cutthrough connection is made).

950TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
951
952 When a queue runner is handling a message, Exim first routes the
953 recipient addresses, during which it prunes them based on the retry
954 hints database. After that it attempts to deliver the message to
955 any remaining recipients. It then updates the hints database using
956 the retry rules.
957
958 So if a recipient address works intermittently, it can get repeatedly
959 deferred at routing time. The retry hints record remains fresh so the
960 address never reaches the final cutoff time.
961
962 This is a fairly common occurrence when a user is bumping up against
963 their storage quota. Exim had some logic in its local delivery code
964 to deal with this. However it did not apply to per-recipient defers
965 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
966
1ddeb334
TF
967 This change adds a proper retry rule check during routing so that the
968 final cutoff time is checked against the message's age. We only do
969 this check if there is an address retry record and there is not a
970 domain retry record; this implies that previous attempts to handle
971 the address had the retry_use_local_parts option turned on. We use
972 this as an approximation for the destination being like a local
973 delivery, as in LMTP.
67bd1ab3
TF
974
975 I suspect this new check makes the old local delivery cutoff check
976 redundant, but I have not verified this so I left the code in place.

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

1011 Server implementation by Todd Lyons, client by JH.
1012 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
1013 config variable "prdr_enable" controls whether the server
1014 advertises the facility. If the client requests PRDR a new
1015 acl_data_smtp_prdr ACL is called once for each recipient, after
1016 the body content is received and before the acl_smtp_data ACL.
4c04137d 1017 The client is controlled by both of: a hosts_try_prdr option

1018 on the smtp transport, and the server advertisement.

1298TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1299 lock up or crash if it happened to be inside a call to libc when it
1300 got a SIGUSR1 from exiwhat.
1301
1302 The SIGUSR1 handler appends the current process status to the process
1303 log which is later printed by exiwhat. It used to use the general
1304 purpose logging code to do this, but several functions it calls are
1305 not safe for signals.
1306
1307 The new output code in the SIGUSR1 handler is specific to the process
1308 log, and simple enough that it's easy to inspect for signal safety.
1309 Removing some special cases also simplifies the general logging code.
1310 Removing the spurious timestamps from the process log simplifies
1311 exiwhat.
1312

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

1572PP/06 Bugzilla 1071: fix delivery logging with untrusted macros.
1573 If dropping privileges for untrusted macros, we disabled normal logging
1574 on the basis that it would fail; for the Exim run-time user, this is not
1575 the case, and it resulted in successful deliveries going unlogged.
1576 Fixed. Reported by Andreas Metzler.

1934PH/01 Another patch from the Sieve maintainer.
1935
6a3bceb1
PH
1936PH/02 When an IPv6 address is converted to a string for single-key lookup
1937 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1938 dots are used instead of colons so that keys in lsearch files need not
1939 contain colons. This was done some time before quoting was made available
1940 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1941 (notated using the quote facility) so as to distinguish them from IPv4
1942 keys. This meant that lookups for IP addresses in host lists did not work
1943 for iplsearch lookups.
1944
1945 This has been fixed by arranging for IPv6 addresses to be expressed with
1946 colons if the lookup type is iplsearch. This is not incompatible, because
1947 previously such lookups could never work.
1948
4c04137d 1949 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
1950 ordinary lsearch keys. However, making the change in all cases is
1951 incompatible and would probably break a number of configurations.

1956MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1957 conversion specification without a maximum field width, thereby enabling
1958 a rogue spamd server to cause a buffer overflow. While nobody in their
1959 right mind would setup Exim to query an untrusted spamd server, an
1960 attacker that gains access to a server running spamd could potentially
1961 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1966MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1967 a directory entry by the name of the lookup key. Previously, if a
1968 symlink pointed to a non-existing file or a file in a directory that
1969 Exim lacked permissions to read, a lookup for a key matching that
1970 symlink would fail. Now it is enough that a matching directory entry
1971 exists, symlink or not. (Bugzilla 503.)

2048 if a client was not listed at all, or was listed with a value other than
2049 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
2050 the condition was not true (as it should be), so access was not denied.

PH
2154PH/29 SMTP synchronization checks are implemented when a command is read -
2155 there is a check that no more input is waiting when there shouldn't be
2156 any. However, for some commands, a delay in an ACL can mean that it is
2157 some time before the response is written. In this time, more input might
2158 arrive, invalidly. So now there are extra checks after an ACL has run for
2159 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2160 pipelining has not been advertised.

PH
2172PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
2173 Exim which did not show up earlier: it was assuming that a call to
2174 SSL_CTX_set_info_callback() might give an error value. In fact, there is
2175 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
2176 was a macro that became an assignment, so it seemed to work. This has
2177 changed to a proper function call with a void return, hence the compile
2178 error. Exim's code has been fixed.

2209 started the daemon, but after a SIGHUP it used the Exim user (because it

2216 with PIPELINING or a stupid MUA), the error message that was given to the
2217 RCPT commands is included in the rejection of the DATA command. This is

PH
2234 the response to the final '.' that terminates a message, but only in the
2235 case where the client has not sent further data following the '.'
2236 (unfortunately, this is allowed). However, in many cases there won't be
2237 any further data because there won't be any more messages to send. A call
2238 to select() can be used: if it shows that the input is "ready", there is
2239 either input waiting, or the socket has been closed. An attempt to read
2240 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2241 would have sent an OK response which the client would never have see.

2252PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2253 fixed by 4.65/MH/01 (is this a record?) are fixed:
2254
2255 (i) An empty string was always treated as zero by the numeric comparison
2256 operators. This behaviour has been restored.
2257
2258 (ii) It is documented that the numeric comparison operators always treat
2259 their arguments as decimal numbers. This was broken in that numbers
2260 starting with 0 were being interpreted as octal.
2261
2262 While fixing these problems I realized that there was another issue that
2263 hadn't been noticed. Values of message_size_limit (both the global option
2264 and the transport option) were treated as octal if they started with 0.
2265 The documentation was vague. These values are now always treated as
2266 decimal, and I will make that clear in the documentation.

2292 leftover -K file (the existence of which was triggered by #402).

2b1c6e3a
PH
2310PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2311 callout verification, Exim cached a "reject" for the entire domain. This
2312 is correct for most verifications, but it is not correct for a recipient
2313 verification with use_sender or use_postmaster set, because in that case
2314 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2315 case of MAIL FROM:<> rejection from other early rejections (e.g.
2316 rejection of HELO). When verifying a recipient using a non-null MAIL
2317 address, the cache is ignored if it shows MAIL FROM:<> rejection.

2354PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2355 hostname. This is wrong, because it relates to the incoming message (and
2356 probably the interface on which it is arriving) and not to the outgoing
2357 callout (which could be using a different interface). This has been
2358 changed to use the value of the helo_data option from the smtp transport
2359 instead - this is what is used when a message is actually being sent. If
2360 there is no remote transport (possible with a router that sets up host
2361 addresses), $smtp_active_hostname is used.

14aa5a05 2363PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2364 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2365 (a) The code assumed that strncpy() returns a negative number on buffer
2366 overflow, which isn't the case. Replaced with Exim's string_format()
2367 function.
2368 (b) There were several signed/unsigned issues. I just did the minimum
2369 hacking in of casts. There is scope for a larger refactoring.
2370 (c) The code used strcasecmp() which is not a standard C function.
2371 Replaced with Exim's strcmpic() function.
2372 (d) The code set only $1; it now sets $auth1 as well.
2373 (e) A simple test gave the error "authentication client didn't specify
2374 service in request". It would seem that Dovecot has changed its
2375 interface. Fortunately there's a specification; I followed it and
2376 changed what the client sends and it appears to be working now.

2381PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2382 address A is aliased to B and C, where B exists and C does not. Without
2383 -v the output is "A verified" because verification stops after a
2384 successful redirection if more than one address is generated. However,
2385 with -v the child addresses are also verified. Exim was outputting "A
2386 failed to verify" and then showing the successful verification for C,
2387 with its parentage. It now outputs "B failed to verify", showing B's
2388 parentage before showing the successful verification of C.

2391 look up a TXT record in a specific list after matching in a combined

2393
322050c2
PH
2394PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2395 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2396 they consult the DNS. I had assumed they would set it the way they
2397 wanted; and indeed my experiments on Linux seem to show that in some
2398 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2399 To be on the safe side, however, I have now made the interface to
2400 host_find_byname() similar to host_find_bydns(), with an argument
2401 containing the DNS resolver options. The host_find_byname() function now
2402 sets these options at its start, just as host_find_bydns() does. The smtp
2403 transport options dns_qualify_single and dns_search_parents are passed to
2404 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2405 of host_find_byname() use the default settings of RES_DEFNAMES
2406 (qualify_single) but not RES_DNSRCH (search_parents).
2407

PH
2408PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2409 spool_read_header() do less string testing, by means of a preliminary
2410 switch on the second character of optional "-foo" lines. (This is
2411 overdue, caused by the large number of possibilities that now exist.
2412 Originally there were few.) While I was there, I also converted the
2413 str(n)cmp tests so they don't re-test the leading "-" and the first
2414 character, in the hope this might squeeze out yet more improvement.
2415

PH
2416PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2417 flag allowing group syntax was set by the header_syntax check but not
2418 turned off, possible causing trouble later; (2) The flag was not being
2419 set at all for the header_verify test, causing "group"-style headers to
2420 be rejected. I have now set it in this case, and also caused header_
2421 verify to ignore an empty address taken from a group. While doing this, I
2422 came across some other cases where the code for allowing group syntax
2423 while scanning a header line wasn't quite right (mostly, not resetting
2424 the flag correctly in the right place). These bugs could have caused
2425 trouble for malformed header lines. I hope it is now all correct.
2426
602e59e5
PH
2427PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2428 with the "reply" argument non-NULL. The code, however (which originally
2429 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2430 but it didn't always do it. This confused somebody who was copying the
2431 code for some other use. I have removed all the tests.
2432
411ef850
PH
2433PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2434 feature that was used to support insecure browsers during the U.S. crypto
2435 embargo. It requires special client support, and Exim is probably the
2436 only MTA that supported it -- and would never use it because real RSA is
2437 always available. This code has been removed, because it had the bad
2438 effect of slowing Exim down by computing (never used) parameters for the
2439 RSA_EXPORT functionality.
2440
7befa435
PH
2441PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2442 authenticator to fail if there's a tab character in the incoming data
2443 (there should never be unless someone is messing about, as it's supposed
2444 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2445 if the connection is using TLS or if the remote IP is the same as the
2446 local IP, and the "valid-client-cert option" if a client certificate has
2447 been verified.

2478
2479PH/30 Exim was sometimes attempting to deliver messages that had suffered
2480 address errors (4xx response to RCPT) over the same connection as other
2481 messages routed to the same hosts. Such deliveries are always "forced",
2482 so retry times are not inspected. This resulted in far too many retries
2483 for the affected addresses. The effect occurred only when there were more
2484 hosts than the hosts_max_try setting in the smtp transport when it had
2485 the 4xx errors. Those hosts that it had tried were not added to the list
2486 of hosts for which the message was waiting, so if all were tried, there
2487 was no problem. Two fixes have been applied:
2488
2489 (i) If there are any address or message errors in an SMTP delivery, none
2490 of the hosts (tried or untried) are now added to the list of hosts
2491 for which the message is waiting, so the message should not be a
2492 candidate for sending over the same connection that was used for a
2493 successful delivery of some other message. This seems entirely
2494 reasonable: after all the message is NOT "waiting for some host".
2495 This is so "obvious" that I'm not sure why it wasn't done
2496 previously. Hope I haven't missed anything, but it can't do any
2497 harm, as the worst effect is to miss an optimization.
2498
2499 (ii) If, despite (i), such a delivery is accidentally attempted, the
2500 routing retry time is respected, so at least it doesn't keep
2501 hammering the server.

2517 written to the panic log as well as the main log, but it isn't really

2519 removed the panic log writing for the ECONNRESET error when getsockname()
2520 fails.

48c7f9e2
PH
2522PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2523 runs only) independently of the message's sender address. This meant
2524 that, if the 4xx error was in fact related to the sender, a different
2525 message to the same recipient with a different sender could confuse
4c04137d 2526 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2527 server, but other circumstances could also provoke similar problems.
2528 I have changed the default so that the retry time for these errors is now
2529 based a combination of the sender and recipient addresses. This change
2530 can be overridden by setting address_retry_include_sender=false in the
2531 smtp transport.

2799PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
2800 "Deny" causes Exim to reject the incoming connection with a 554 error.
2801 Unfortunately, if there is a major crisis, such as a disk failure,
2802 tcp-wrappers gives "deny", whereas what one would like would be some
2803 kind of temporary error. A kludge has been added to help with this.
2804 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2805 554 error is used if errno is still zero or contains ENOENT (which occurs
2806 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2807 451 error is used.

2843PH/01 The code for finding all the local interface addresses on a FreeBSD
2844 system running IPv6 was broken. This may well have applied to all BSD
2845 systems, as well as to others that have similar system calls. The broken
2846 code found IPv4 interfaces correctly, but gave incorrect values for the
2847 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2848 that it would not match correctly against @[] and not recognize the IPv6
2849 addresses as local.

2892 autoreply, Exim could try to deliver to a non-existent relative file

2927 additional section of a DNS packet that returns MX or SRV records.
2928 Instead, it always explicitly searches for A/AAAA records. This avoids
2929 major problems that occur when a DNS server includes only records of one
2930 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2931 fixed another bug: if SRV records were looked up and the corresponding
2932 address records were *not* found in the additional section, the port
2933 values from the SRV records were lost.

2935PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2943PH/19 When calculating a retry time, Exim used to measure the "time since
2944 failure" by looking at the "first failed" field in the retry record. Now
2945 it does not use this if it is later than than the arrival time of the
2946 message. Instead it uses the arrival time. This makes for better
2947 behaviour in cases where some deliveries succeed, thus re-setting the
2948 "first failed" field. An example is a quota failure for a huge message
2949 when small messages continue to be delivered. Without this change, the
2950 "time since failure" will always be short, possible causing more frequent
2951 delivery attempts for the huge message than are intended.

3048PH/42 The content-scanning code uses fopen() to create files in which to put

3051 files with open(), and sets the required mode explicitly. Thus, these
3052 files were ending up world-writeable. This was not a big issue, because,
3053 being within the spool directory, they were not world-accessible. I have
3054 created a function called modefopen, which takes an additional mode
3055 argument. It sets umask(777), creates the file, chmods it to the required
3056 mode, then resets the umask. All the relevant calls to fopen() in the

3085 directory of message files (e.g. for maildir delivery) to find the count
3086 of files (along with the size), even though it did not need this
3087 information. It now does the scan only if it needs to find either the
3088 size of the count of files.

3092PH/52 Two bugs concerned with error handling when the smtp transport is
3093 used in LMTP mode:
3094
3095 (i) Exim was not creating retry information for temporary errors given
3096 for individual recipients after the DATA command when the smtp transport
3097 was used in LMTP mode. This meant that they could be retried too
3098 frequently, and not timed out correctly.
3099
3100 (ii) Exim was setting the flag that allows error details to be returned
3101 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3102 recipients that were returned after the DATA command.
3103
3104PH/53 This is related to PH/52, but is more general: for any failing address,
3105 when detailed error information was permitted to be returned to the
3106 sender, but the error was temporary, then after the final timeout, only
3107 "retry timeout exceeded" was returned. Now it returns the full error as
3108 well as "retry timeout exceeded".

3164PH/68 The bounce_return_message and bounce_return_body options were not being
3165 honoured for bounces generated during the reception of non-SMTP messages.
3166 In particular, this applied to messages rejected by the ACL. This bug has
3167 been fixed. However, if bounce_return_message is true and bounce_return_
3168 body is false, the headers that are returned for a non-SMTP message
3169 include only those that have been read before the error was detected.

3172PH/69 The HTML version of the specification is now built in a directory called

3178PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3179 function verify_get_ident() calls ip_connect() to connect a socket, but
3180 if the "connect()" function timed out, ip_connect() used to close the
3181 socket. However, verify_get_ident() also closes the socket later, and in
3182 between Exim writes to the log, which may get opened at this point. When
3183 the socket was closed in ip_connect(), the log could get the same file
3184 descriptor number as the socket. This naturally causes chaos. The fix is
3185 not to close the socket in ip_connect(); the socket should be closed by
3186 the function that creates it. There was only one place in the code where
3187 this was missing, in the iplookup router, which I don't think anybody now
3188 uses, but I've fixed it anyway.

3207PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3208
3209 (1) Generate an error if the third argument for the ${prvs expansion is
3210 not a single digit.
3211
3212 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3213 string.
3214
3215 (3) Reset the variables that are obtained from the first argument of
3216 ${prvscheck and used in the second argument before leaving the code,
3217 because their memory is reclaimed, so using them afterwards may do
3218 silly things.
3219
3220 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3221 one (it's much easier than Tom thought :-).
3222
3223 (5) Because of (4), we can now allow for the use of $prvscheck_result
3224 inside the third argument.

3233PH/05 When a filter generated an autoreply, the entire To: header line was
3234 quoted in the delivery log line, like this:
3235
3236 => >A.N.Other <ano@some.domain> <original@ddress> ...
3237
3238 This has been changed so that it extracts the operative address. There
3239 may be more than one such address. If so, they are comma-separated, like
3240 this:
3241
3242 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
3244PH/06 When a client host used a correct literal IP address in a HELO or EHLO
3245 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3246 not being looked up in the rDNS to get a host name, Exim was showing the
3247 IP address twice in Received: lines, even though the IP addresses were
3248 identical. For example:
3249
3250 Received: from [1.2.3.4] (helo=[1.2.3.4])
3251
3252 However, if the real host name was known, it was omitting the HELO data
3253 if it matched the actual IP address. This has been tidied up so that it
3254 doesn't show the same IP address twice.

3256PH/07 When both +timestamp and +memory debugging was on, the value given by
