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.

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
5013d912 27 Certificate or OCSP information. TLS cipher information is still logged.

30 identical IP addresses on different listening ports. Will also affect
31 "exiwhat" output.

37JH/05 Tighten up the checking in isip4 (et al): dotted-quad components larger
38 than 255 are no longer allowed.
39

JH
40JH/06 Default openssl_options to include +no_ticket, to reduce load on peers.
41 Disable the session-cache too, which might reduce our load. Since we
42 currrectly use a new context for every connection, both as server and
43 client, there is no benefit for these.
44 GnuTLS appears to not support tickets server-side by default (we don't
45 call gnutls_session_ticket_enable_server()) but client side is enabled
46 by default on recent versions (3.1.3 +) unless the PFS priority string
47 is used (3.2.4 +).

JH
52JH/07 Fix smtp transport use of limited max_rcpt under mua_wrapper. Previously
53 the check for any unsuccessful recipients did not notice the limit, and
54 erroneously found still-pending ones.
55
4e910c01
JH
56JH/08 Pipeline CHUNKING command and data together, on kernels that support
57 MSG_MORE. Only in-clear (not on TLS connections).
58
42055a33
JH
59JH/09 Avoid using a temporary file during transport using dkim. Unless a
60 transport-filter is involved we can buffer the headers in memory for
61 creating the signature, and read the spool data file once for the
62 signature and again for transmission.
63
eeb35890
JH
64JH/10 Enable use of sendfile in Linux builds as default. It was disabled in
65 4.77 as the kernel support then wasn't solid, having issues in 64bit
7d758a6a 66 mode. Now, it's been long enough. Add support for FreeBSD also.

JH
68JH/11 Bug 2104: Fix continued use of a transport connection with TLS. In the
69 case where the routing stage had gathered several addresses to send to
70 a host before calling the transport for the first, we previously failed
71 to close down TLS in the old transport process before passing the TCP
72 connection to the new process. The new one sent a STARTTLS command
73 which naturally failed, giving a failed delivery and bloating the retry
74 database. Investigation and fix prototype from Wolfgang Breyha.
75
40525d07
JH
76JH/12 Fix check on SMTP command input synchronisation. Previously there were
77 false-negatives in the check that the sender had not preempted a response
78 or prompt from Exim (running as a server), due to that code's lack of
a5ffa9b4 79 awareness of the SMTP input buffering.
40525d07 80
f33875c3
PP
81PP/04 Add commandline_checks_require_admin option.
82 Exim drops privileges sanely, various checks such as -be aren't a
83 security problem, as long as you trust local users with access to their
84 own account. When invoked by services which pass untrusted data to
85 Exim, this might be an issue. Set this option in main configuration
86 AND make fixes to the calling application, such as using `--` to stop
87 processing options.
88
a5ffa9b4
JH
89JH/13 Do pipelining under TLS. Previously, although safe, no advantage was
90 taken. Now take care to pack both (client) MAIL,RCPT,DATA, and (server)
91 responses to those, into a single TLS record each way (this usually means
92 a single packet). As a side issue, smtp_enforce_sync now works on TLS
93 connections.

95PP/05 OpenSSL/1.1: use DH_bits() for more accurate DH param sizes. This
96 affects you only if you're dancing at the edge of the param size limits.
97 If you are, and this message makes sense to you, then: raise the
98 configured limit or use OpenSSL 1.1. Nothing we can do for older
99 versions.

185JH/12 Bug 2018: Re-order Proxy Protocol startup versus TLS-on-connect startup.
186 It seems that HAProxy sends the Proxy Protocol information in clear and
187 only then does a TLS startup, so do the same.
188
189JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
190 TCP connections (such as for Spamd) unless the daemon successfully set
191 Fast Open mode on its listening sockets. This fixes breakage seen on
192 too-old kernels or those not configured for Fast Open, at the cost of
193 requiring both directions being enabled for TFO, and TFO never being used
194 by non-daemon-related Exim processes.
195
196JH/14 Bug 2000: Reject messages recieved with CHUNKING but with malformed line

212JH/16 Drop variables when they go out of scope. Memory management drops a whole
213 region in one operation, for speed, and this leaves assigned pointers

215 variables at a store-reset and panics on a dangling pointer; add code
216 explicitly nulling out all the variables discovered. Fixes one known

JH
255JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
256 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
257 or even an in-clear connection were permitted. Now, if the host lookup
258 was dnssec and dane was requested then the host is only used if the
259 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
260 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
261 if one fails this test.
262 This means that a poorly-configured remote DNS will make it incommunicado;
263 but it protects against a DNS-interception attack on it.

285JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
286 a cutthrough deliver is pending, as we always want to make a connection.

288 connection after a verify cache hit.

401 The I= interface field on outgoing lines is now after the H= remote
402 host field, same as incoming lines. There is a separate
403 outgoing_interface log selector which allows you to disable the
404 outgoing I= field.

408 open indefinitely after a "too many connections" event, including to a
409 deleted file after a log rotate. Leave the per net connection logging
410 leaving it open for efficiency as that will be quickly detected by the

829 delivery connection happened to have the same fd number as the incoming

1077TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
1078
1079 When a queue runner is handling a message, Exim first routes the
1080 recipient addresses, during which it prunes them based on the retry
1081 hints database. After that it attempts to deliver the message to
1082 any remaining recipients. It then updates the hints database using
1083 the retry rules.
1084
1085 So if a recipient address works intermittently, it can get repeatedly
1086 deferred at routing time. The retry hints record remains fresh so the
1087 address never reaches the final cutoff time.
1088
1089 This is a fairly common occurrence when a user is bumping up against
1090 their storage quota. Exim had some logic in its local delivery code
1091 to deal with this. However it did not apply to per-recipient defers
1092 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1093
1ddeb334
TF
1094 This change adds a proper retry rule check during routing so that the
1095 final cutoff time is checked against the message's age. We only do
1096 this check if there is an address retry record and there is not a
1097 domain retry record; this implies that previous attempts to handle
1098 the address had the retry_use_local_parts option turned on. We use
1099 this as an approximation for the destination being like a local
1100 delivery, as in LMTP.
67bd1ab3
TF
1101
1102 I suspect this new check makes the old local delivery cutoff check
1103 redundant, but I have not verified this so I left the code in place.

1425TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1426 lock up or crash if it happened to be inside a call to libc when it
1427 got a SIGUSR1 from exiwhat.
1428
1429 The SIGUSR1 handler appends the current process status to the process
1430 log which is later printed by exiwhat. It used to use the general
1431 purpose logging code to do this, but several functions it calls are
1432 not safe for signals.
1433
1434 The new output code in the SIGUSR1 handler is specific to the process
1435 log, and simple enough that it's easy to inspect for signal safety.
1436 Removing some special cases also simplifies the general logging code.
1437 Removing the spurious timestamps from the process log simplifies
1438 exiwhat.
1439
c99ce5c9
TF
1440TF/04 Improved ratelimit ACL condition.
1441
1442 The /noupdate option has been deprecated in favour of /readonly which
1443 has clearer semantics. The /leaky, /strict, and /readonly update modes
1444 are mutually exclusive. The update mode is no longer included in the
1445 database key; it just determines when the database is updated. (This
4c04137d 1446 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1447
1448 Exim now checks that the per_* options are used with an update mode that
1449 makes sense for the current ACL. For example, when Exim is processing a
1450 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1451 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1452 must specify per_mail/readonly. If you omit the update mode it defaults to
1453 /leaky where that makes sense (as before) or /readonly where required.
1454
1455 The /noupdate option is now undocumented but still supported for
1456 backwards compatibility. It is equivalent to /readonly except that in
1457 ACLs where /readonly is required you may specify /leaky/noupdate or
1458 /strict/noupdate which are treated the same as /readonly.
1459
1460 A useful new feature is the /count= option. This is a generalization
1461 of the per_byte option, so that you can measure the throughput of other
1462 aggregate values. For example, the per_byte option is now equivalent
1463 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1464
1465 The per_rcpt option has been generalized using the /count= mechanism
1466 (though it's more complicated than the per_byte equivalence). When it is
1467 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1468 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1469 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1470 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1471 Note that using per_rcpt with a non-readonly update mode in more than
1472 one ACL will cause the recipients to be double-counted. (The per_mail
1473 and per_byte options don't have this problem.)
1474
1475 The handling of very low rates has changed slightly. If the computed rate
1476 is less than the event's count (usually one) then this event is the first
1477 after a long gap. In this case the rate is set to the same as this event's
1478 count, so that the first message of a spam run is counted properly.
1479
1480 The major new feature is a mechanism for counting the rate of unique
1481 events. The new per_addr option counts the number of different
1482 recipients that someone has sent messages to in the last time period. It
1483 behaves like per_rcpt if all the recipient addresses are different, but
1484 duplicate recipient addresses do not increase the measured rate. Like
1485 the /count= option this is a general mechanism, so the per_addr option
1486 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1487 example, measure the rate that a client uses different sender addresses
1488 with the options per_mail/unique=$sender_address. There are further
1489 details in the main documentation.

2040 were called 'true' and it seems that C99 defines that as a reserved

2059-----------------
2060
2061PH/01 Another patch from the Sieve maintainer.
2062
6a3bceb1
PH
2063PH/02 When an IPv6 address is converted to a string for single-key lookup
2064 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
2065 dots are used instead of colons so that keys in lsearch files need not
2066 contain colons. This was done some time before quoting was made available
2067 in lsearch files. However, iplsearch files do require colons in IPv6 keys
2068 (notated using the quote facility) so as to distinguish them from IPv4
2069 keys. This meant that lookups for IP addresses in host lists did not work
2070 for iplsearch lookups.
2071
2072 This has been fixed by arranging for IPv6 addresses to be expressed with
2073 colons if the lookup type is iplsearch. This is not incompatible, because
2074 previously such lookups could never work.
2075
4c04137d 2076 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2077 ordinary lsearch keys. However, making the change in all cases is
2078 incompatible and would probably break a number of configurations.
2079

2082

MH
2083MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2084 conversion specification without a maximum field width, thereby enabling
2085 a rogue spamd server to cause a buffer overflow. While nobody in their
2086 right mind would setup Exim to query an untrusted spamd server, an
2087 attacker that gains access to a server running spamd could potentially
2088 exploit this vulnerability to run arbitrary code as the Exim user.

2092
0f2cbd1b
MH
2093MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2094 a directory entry by the name of the lookup key. Previously, if a
2095 symlink pointed to a non-existing file or a file in a directory that
2096 Exim lacked permissions to read, a lookup for a key matching that
2097 symlink would fail. Now it is enough that a matching directory entry
2098 exists, symlink or not. (Bugzilla 503.)

2175 if a client was not listed at all, or was listed with a value other than
2176 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,

2281PH/29 SMTP synchronization checks are implemented when a command is read -
2282 there is a check that no more input is waiting when there shouldn't be

2284 some time before the response is written. In this time, more input might
2285 arrive, invalidly. So now there are extra checks after an ACL has run for
2286 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2287 pipelining has not been advertised.

2302 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()

2336 started the daemon, but after a SIGHUP it used the Exim user (because it
2337 calls itself on a restart). I have changed the code so that it now always
2338 uses the Exim user.

2343 with PIPELINING or a stupid MUA), the error message that was given to the

PH
2361 the response to the final '.' that terminates a message, but only in the
2362 case where the client has not sent further data following the '.'
2363 (unfortunately, this is allowed). However, in many cases there won't be
2364 any further data because there won't be any more messages to send. A call
2365 to select() can be used: if it shows that the input is "ready", there is
2366 either input waiting, or the socket has been closed. An attempt to read
2367 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2368 would have sent an OK response which the client would never have see.

2379PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2380 fixed by 4.65/MH/01 (is this a record?) are fixed:
2381
2382 (i) An empty string was always treated as zero by the numeric comparison
2383 operators. This behaviour has been restored.
2384
2385 (ii) It is documented that the numeric comparison operators always treat
2386 their arguments as decimal numbers. This was broken in that numbers
2387 starting with 0 were being interpreted as octal.
2388
2389 While fixing these problems I realized that there was another issue that
2390 hadn't been noticed. Values of message_size_limit (both the global option
2391 and the transport option) were treated as octal if they started with 0.
2392 The documentation was vague. These values are now always treated as
2393 decimal, and I will make that clear in the documentation.

2407PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
2408 child addresses, Exim now panics and dies. Previously, because the count
2409 is held in a short int, deliveries were likely to be lost. As such a
2410 large number of recipients for a single message is ridiculous
2411 (performance will be very, very poor), I have chosen to impose a limit
2412 rather than extend the field.

PH
2437PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2438 callout verification, Exim cached a "reject" for the entire domain. This
2439 is correct for most verifications, but it is not correct for a recipient
2440 verification with use_sender or use_postmaster set, because in that case
2441 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2442 case of MAIL FROM:<> rejection from other early rejections (e.g.
2443 rejection of HELO). When verifying a recipient using a non-null MAIL
2444 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2445 Whatever the result of the callout, the value of the domain cache is
2446 left unchanged (for any other kind of callout, getting as far as trying
2447 RCPT means that the domain itself is ok).

2483 probably the interface on which it is arriving) and not to the outgoing
2484 callout (which could be using a different interface). This has been
2485 changed to use the value of the helo_data option from the smtp transport
2486 instead - this is what is used when a message is actually being sent. If
2487 there is no remote transport (possible with a router that sets up host
2488 addresses), $smtp_active_hostname is used.

7befa435 2491 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2492 (a) The code assumed that strncpy() returns a negative number on buffer
2493 overflow, which isn't the case. Replaced with Exim's string_format()
2494 function.
2495 (b) There were several signed/unsigned issues. I just did the minimum
2496 hacking in of casts. There is scope for a larger refactoring.
2497 (c) The code used strcasecmp() which is not a standard C function.
2498 Replaced with Exim's strcmpic() function.
2499 (d) The code set only $1; it now sets $auth1 as well.
2500 (e) A simple test gave the error "authentication client didn't specify
2501 service in request". It would seem that Dovecot has changed its
2502 interface. Fortunately there's a specification; I followed it and
2503 changed what the client sends and it appears to be working now.

2509 address A is aliased to B and C, where B exists and C does not. Without
2510 -v the output is "A verified" because verification stops after a
2511 successful redirection if more than one address is generated. However,
2512 with -v the child addresses are also verified. Exim was outputting "A
2513 failed to verify" and then showing the successful verification for C,
2514 with its parentage. It now outputs "B failed to verify", showing B's
2515 parentage before showing the successful verification of C.

322050c2
PH
2521PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2522 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2523 they consult the DNS. I had assumed they would set it the way they
2524 wanted; and indeed my experiments on Linux seem to show that in some
2525 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2526 To be on the safe side, however, I have now made the interface to
2527 host_find_byname() similar to host_find_bydns(), with an argument
2528 containing the DNS resolver options. The host_find_byname() function now
2529 sets these options at its start, just as host_find_bydns() does. The smtp
2530 transport options dns_qualify_single and dns_search_parents are passed to
2531 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2532 of host_find_byname() use the default settings of RES_DEFNAMES
2533 (qualify_single) but not RES_DNSRCH (search_parents).

2535PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2536 spool_read_header() do less string testing, by means of a preliminary
2537 switch on the second character of optional "-foo" lines. (This is
2538 overdue, caused by the large number of possibilities that now exist.
2539 Originally there were few.) While I was there, I also converted the
2540 str(n)cmp tests so they don't re-test the leading "-" and the first
2541 character, in the hope this might squeeze out yet more improvement.

2543PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2544 flag allowing group syntax was set by the header_syntax check but not
2545 turned off, possible causing trouble later; (2) The flag was not being
2546 set at all for the header_verify test, causing "group"-style headers to
2547 be rejected. I have now set it in this case, and also caused header_
2548 verify to ignore an empty address taken from a group. While doing this, I
2549 came across some other cases where the code for allowing group syntax
2550 while scanning a header line wasn't quite right (mostly, not resetting
2551 the flag correctly in the right place). These bugs could have caused
2552 trouble for malformed header lines. I hope it is now all correct.

PH
2554PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2555 with the "reply" argument non-NULL. The code, however (which originally
2556 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2557 but it didn't always do it. This confused somebody who was copying the
2558 code for some other use. I have removed all the tests.

PH
2560PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2561 feature that was used to support insecure browsers during the U.S. crypto
2562 embargo. It requires special client support, and Exim is probably the
2563 only MTA that supported it -- and would never use it because real RSA is
2564 always available. This code has been removed, because it had the bad
2565 effect of slowing Exim down by computing (never used) parameters for the
2566 RSA_EXPORT functionality.

PH
2568PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2569 authenticator to fail if there's a tab character in the incoming data

2571 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2572 if the connection is using TLS or if the remote IP is the same as the
2573 local IP, and the "valid-client-cert option" if a client certificate has
2574 been verified.

PH
2605
2606PH/30 Exim was sometimes attempting to deliver messages that had suffered
2607 address errors (4xx response to RCPT) over the same connection as other
2608 messages routed to the same hosts. Such deliveries are always "forced",
2609 so retry times are not inspected. This resulted in far too many retries
2610 for the affected addresses. The effect occurred only when there were more
2611 hosts than the hosts_max_try setting in the smtp transport when it had
2612 the 4xx errors. Those hosts that it had tried were not added to the list
2613 of hosts for which the message was waiting, so if all were tried, there
2614 was no problem. Two fixes have been applied:
2615
2616 (i) If there are any address or message errors in an SMTP delivery, none
2617 of the hosts (tried or untried) are now added to the list of hosts
2618 for which the message is waiting, so the message should not be a
2619 candidate for sending over the same connection that was used for a
2620 successful delivery of some other message. This seems entirely
2621 reasonable: after all the message is NOT "waiting for some host".
2622 This is so "obvious" that I'm not sure why it wasn't done
2623 previously. Hope I haven't missed anything, but it can't do any
2624 harm, as the worst effect is to miss an optimization.
2625
2626 (ii) If, despite (i), such a delivery is accidentally attempted, the
2627 routing retry time is respected, so at least it doesn't keep
2628 hammering the server.

2644 written to the panic log as well as the main log, but it isn't really

2646 removed the panic log writing for the ECONNRESET error when getsockname()
2647 fails.

48c7f9e2
PH
2649PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2650 runs only) independently of the message's sender address. This meant
2651 that, if the 4xx error was in fact related to the sender, a different
2652 message to the same recipient with a different sender could confuse
4c04137d 2653 things. In particular, this can happen when sending to a greylisting

2654 server, but other circumstances could also provoke similar problems.
2655 I have changed the default so that the retry time for these errors is now

2926PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2928 Unfortunately, if there is a major crisis, such as a disk failure,
2929 tcp-wrappers gives "deny", whereas what one would like would be some
2930 kind of temporary error. A kludge has been added to help with this.
2931 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2932 554 error is used if errno is still zero or contains ENOENT (which occurs
2933 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2934 451 error is used.

2973 code found IPv4 interfaces correctly, but gave incorrect values for the
2974 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2975 that it would not match correctly against @[] and not recognize the IPv6
2976 addresses as local.

3019 autoreply, Exim could try to deliver to a non-existent relative file

3055 Instead, it always explicitly searches for A/AAAA records. This avoids
3056 major problems that occur when a DNS server includes only records of one
3057 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
3058 fixed another bug: if SRV records were looked up and the corresponding
3059 address records were *not* found in the additional section, the port
3060 values from the SRV records were lost.

PH
3070PH/19 When calculating a retry time, Exim used to measure the "time since
3071 failure" by looking at the "first failed" field in the retry record. Now
3072 it does not use this if it is later than than the arrival time of the
3073 message. Instead it uses the arrival time. This makes for better
3074 behaviour in cases where some deliveries succeed, thus re-setting the
3075 "first failed" field. An example is a quota failure for a huge message
3076 when small messages continue to be delivered. Without this change, the
3077 "time since failure" will always be short, possible causing more frequent
3078 delivery attempts for the huge message than are intended.

3150 same order.

PH
3175PH/42 The content-scanning code uses fopen() to create files in which to put
3176 message data. Previously it was not paying any attention to the mode of
3177 the files. Exim runs with umask(0) because the rest of the code creates
3178 files with open(), and sets the required mode explicitly. Thus, these
3179 files were ending up world-writeable. This was not a big issue, because,
3180 being within the spool directory, they were not world-accessible. I have
3181 created a function called modefopen, which takes an additional mode
3182 argument. It sets umask(777), creates the file, chmods it to the required
3183 mode, then resets the umask. All the relevant calls to fopen() in the
3184 content scanning code have been changed to use this function.

3192PH/45 When the plaintext authenticator is running as a client, the server's
3193 challenges are checked to ensure they are valid base64 strings. By
3194 default, the authentication attempt is cancelled if an invalid string is
3195 received. Setting client_ignore_invalid_base64 true ignores these errors.
3196 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
3197 they are received. Thus, the responses can be made to depend on the
3198 challenges. If an invalid string is ignored, an empty string is placed in
3199 the variable.

3210PH/50 When an Exim quota was set without a file count quota, and mailbox_size
3211 was also set, the appendfile transport was unnecessarily scanning a
3212 directory of message files (e.g. for maildir delivery) to find the count
3213 of files (along with the size), even though it did not need this
3214 information. It now does the scan only if it needs to find either the
3215 size of the count of files.

3219PH/52 Two bugs concerned with error handling when the smtp transport is
3220 used in LMTP mode:
3221
3222 (i) Exim was not creating retry information for temporary errors given
3223 for individual recipients after the DATA command when the smtp transport
3224 was used in LMTP mode. This meant that they could be retried too
3225 frequently, and not timed out correctly.
3226
3227 (ii) Exim was setting the flag that allows error details to be returned
3228 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3229 recipients that were returned after the DATA command.
3230
3231PH/53 This is related to PH/52, but is more general: for any failing address,
3232 when detailed error information was permitted to be returned to the
3233 sender, but the error was temporary, then after the final timeout, only
3234 "retry timeout exceeded" was returned. Now it returns the full error as
3235 well as "retry timeout exceeded".
