9-----------------

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.

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.

37JH/05 Tighten up the checking in isip4 (et al): dotted-quad components larger

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 +).

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.

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

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.

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.

263JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
264 TCP connections (such as for Spamd) unless the daemon successfully set
265 Fast Open mode on its listening sockets. This fixes breakage seen on
266 too-old kernels or those not configured for Fast Open, at the cost of
267 requiring both directions being enabled for TFO, and TFO never being used

329JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
330 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
331 or even an in-clear connection were permitted. Now, if the host lookup
332 was dnssec and dane was requested then the host is only used if the
333 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
334 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
335 if one fails this test.
336 This means that a poorly-configured remote DNS will make it incommunicado;
337 but it protects against a DNS-interception attack on it.

1151TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
1152
1153 When a queue runner is handling a message, Exim first routes the
1154 recipient addresses, during which it prunes them based on the retry
1155 hints database. After that it attempts to deliver the message to
1156 any remaining recipients. It then updates the hints database using
1157 the retry rules.
1158
1159 So if a recipient address works intermittently, it can get repeatedly
1160 deferred at routing time. The retry hints record remains fresh so the
1161 address never reaches the final cutoff time.
1162
1163 This is a fairly common occurrence when a user is bumping up against
1164 their storage quota. Exim had some logic in its local delivery code
1165 to deal with this. However it did not apply to per-recipient defers
1166 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1167

TF
1168 This change adds a proper retry rule check during routing so that the
1169 final cutoff time is checked against the message's age. We only do
1170 this check if there is an address retry record and there is not a
1171 domain retry record; this implies that previous attempts to handle
1172 the address had the retry_use_local_parts option turned on. We use
1173 this as an approximation for the destination being like a local
1174 delivery, as in LMTP.

TF
1175
1176 I suspect this new check makes the old local delivery cutoff check
1177 redundant, but I have not verified this so I left the code in place.

1185 When I ran the test suite under the user fanf2, Exim expanded
1186 the header to contain my full name, whereas it should have added
1187 a Resent-Sender: header. It erroneously treats any prefix of the

1499TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1500 lock up or crash if it happened to be inside a call to libc when it
1501 got a SIGUSR1 from exiwhat.
1502
1503 The SIGUSR1 handler appends the current process status to the process
1504 log which is later printed by exiwhat. It used to use the general
1505 purpose logging code to do this, but several functions it calls are
1506 not safe for signals.
1507
1508 The new output code in the SIGUSR1 handler is specific to the process
1509 log, and simple enough that it's easy to inspect for signal safety.
1510 Removing some special cases also simplifies the general logging code.
1511 Removing the spurious timestamps from the process log simplifies
1512 exiwhat.

c99ce5c9
TF
1514TF/04 Improved ratelimit ACL condition.
1515
1516 The /noupdate option has been deprecated in favour of /readonly which
1517 has clearer semantics. The /leaky, /strict, and /readonly update modes
1518 are mutually exclusive. The update mode is no longer included in the
1519 database key; it just determines when the database is updated. (This
4c04137d 1520 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1521
1522 Exim now checks that the per_* options are used with an update mode that
1523 makes sense for the current ACL. For example, when Exim is processing a
1524 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1525 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1526 must specify per_mail/readonly. If you omit the update mode it defaults to
1527 /leaky where that makes sense (as before) or /readonly where required.
1528
1529 The /noupdate option is now undocumented but still supported for
1530 backwards compatibility. It is equivalent to /readonly except that in
1531 ACLs where /readonly is required you may specify /leaky/noupdate or
1532 /strict/noupdate which are treated the same as /readonly.
1533
1534 A useful new feature is the /count= option. This is a generalization
1535 of the per_byte option, so that you can measure the throughput of other
1536 aggregate values. For example, the per_byte option is now equivalent
1537 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1538
1539 The per_rcpt option has been generalized using the /count= mechanism
1540 (though it's more complicated than the per_byte equivalence). When it is
1541 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1542 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1543 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1544 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1545 Note that using per_rcpt with a non-readonly update mode in more than
1546 one ACL will cause the recipients to be double-counted. (The per_mail
1547 and per_byte options don't have this problem.)
1548
1549 The handling of very low rates has changed slightly. If the computed rate
1550 is less than the event's count (usually one) then this event is the first
1551 after a long gap. In this case the rate is set to the same as this event's
1552 count, so that the first message of a spam run is counted properly.
1553
1554 The major new feature is a mechanism for counting the rate of unique
1555 events. The new per_addr option counts the number of different
1556 recipients that someone has sent messages to in the last time period. It
1557 behaves like per_rcpt if all the recipient addresses are different, but
1558 duplicate recipient addresses do not increase the measured rate. Like
1559 the /count= option this is a general mechanism, so the per_addr option
1560 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1561 example, measure the rate that a client uses different sender addresses
1562 with the options per_mail/unique=$sender_address. There are further
1563 details in the main documentation.

2114 were called 'true' and it seems that C99 defines that as a reserved

2136
6a3bceb1
PH
2137PH/02 When an IPv6 address is converted to a string for single-key lookup
2138 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
2139 dots are used instead of colons so that keys in lsearch files need not
2140 contain colons. This was done some time before quoting was made available
2141 in lsearch files. However, iplsearch files do require colons in IPv6 keys
2142 (notated using the quote facility) so as to distinguish them from IPv4
2143 keys. This meant that lookups for IP addresses in host lists did not work
2144 for iplsearch lookups.
2145
2146 This has been fixed by arranging for IPv6 addresses to be expressed with
2147 colons if the lookup type is iplsearch. This is not incompatible, because
2148 previously such lookups could never work.
2149
4c04137d 2150 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2151 ordinary lsearch keys. However, making the change in all cases is
2152 incompatible and would probably break a number of configurations.

2157MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2158 conversion specification without a maximum field width, thereby enabling
2159 a rogue spamd server to cause a buffer overflow. While nobody in their
2160 right mind would setup Exim to query an untrusted spamd server, an
2161 attacker that gains access to a server running spamd could potentially
2162 exploit this vulnerability to run arbitrary code as the Exim user.

MH
2167MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2168 a directory entry by the name of the lookup key. Previously, if a
2169 symlink pointed to a non-existing file or a file in a directory that
2170 Exim lacked permissions to read, a lookup for a key matching that
2171 symlink would fail. Now it is enough that a matching directory entry
2172 exists, symlink or not. (Bugzilla 503.)

2355PH/29 SMTP synchronization checks are implemented when a command is read -
2356 there is a check that no more input is waiting when there shouldn't be

2358 some time before the response is written. In this time, more input might
2359 arrive, invalidly. So now there are extra checks after an ACL has run for
2360 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2361 pipelining has not been advertised.

PH
2435 the response to the final '.' that terminates a message, but only in the
2436 case where the client has not sent further data following the '.'
2437 (unfortunately, this is allowed). However, in many cases there won't be
2438 any further data because there won't be any more messages to send. A call
2439 to select() can be used: if it shows that the input is "ready", there is
2440 either input waiting, or the socket has been closed. An attempt to read
2441 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2442 would have sent an OK response which the client would never have see.

2452
2453PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2454 fixed by 4.65/MH/01 (is this a record?) are fixed:
2455
2456 (i) An empty string was always treated as zero by the numeric comparison
2457 operators. This behaviour has been restored.
2458
2459 (ii) It is documented that the numeric comparison operators always treat
2460 their arguments as decimal numbers. This was broken in that numbers
2461 starting with 0 were being interpreted as octal.
2462
2463 While fixing these problems I realized that there was another issue that
2464 hadn't been noticed. Values of message_size_limit (both the global option
2465 and the transport option) were treated as octal if they started with 0.
2466 The documentation was vague. These values are now always treated as
2467 decimal, and I will make that clear in the documentation.

2483 is held in a short int, deliveries were likely to be lost. As such a
2484 large number of recipients for a single message is ridiculous
2485 (performance will be very, very poor), I have chosen to impose a limit
2486 rather than extend the field.

2493 leftover -K file (the existence of which was triggered by #402).

2502TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

PH
2511PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2512 callout verification, Exim cached a "reject" for the entire domain. This
2513 is correct for most verifications, but it is not correct for a recipient
2514 verification with use_sender or use_postmaster set, because in that case
2515 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2516 case of MAIL FROM:<> rejection from other early rejections (e.g.
2517 rejection of HELO). When verifying a recipient using a non-null MAIL
2518 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2519 Whatever the result of the callout, the value of the domain cache is
2520 left unchanged (for any other kind of callout, getting as far as trying
2521 RCPT means that the domain itself is ok).

2555PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2557 probably the interface on which it is arriving) and not to the outgoing
2558 callout (which could be using a different interface). This has been
2559 changed to use the value of the helo_data option from the smtp transport
2560 instead - this is what is used when a message is actually being sent. If
2561 there is no remote transport (possible with a router that sets up host
2562 addresses), $smtp_active_hostname is used.

7befa435 2565 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2566 (a) The code assumed that strncpy() returns a negative number on buffer
2567 overflow, which isn't the case. Replaced with Exim's string_format()
2568 function.
2569 (b) There were several signed/unsigned issues. I just did the minimum
2570 hacking in of casts. There is scope for a larger refactoring.
2571 (c) The code used strcasecmp() which is not a standard C function.
2572 Replaced with Exim's strcmpic() function.
2573 (d) The code set only $1; it now sets $auth1 as well.
2574 (e) A simple test gave the error "authentication client didn't specify
2575 service in request". It would seem that Dovecot has changed its
2576 interface. Fortunately there's a specification; I followed it and
2577 changed what the client sends and it appears to be working now.

2583 address A is aliased to B and C, where B exists and C does not. Without
2584 -v the output is "A verified" because verification stops after a
2585 successful redirection if more than one address is generated. However,
2586 with -v the child addresses are also verified. Exim was outputting "A
2587 failed to verify" and then showing the successful verification for C,
2588 with its parentage. It now outputs "B failed to verify", showing B's
2589 parentage before showing the successful verification of C.

2594
322050c2
PH
2595PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2596 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2597 they consult the DNS. I had assumed they would set it the way they
2598 wanted; and indeed my experiments on Linux seem to show that in some
2599 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2600 To be on the safe side, however, I have now made the interface to
2601 host_find_byname() similar to host_find_bydns(), with an argument
2602 containing the DNS resolver options. The host_find_byname() function now
2603 sets these options at its start, just as host_find_bydns() does. The smtp
2604 transport options dns_qualify_single and dns_search_parents are passed to
2605 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2606 of host_find_byname() use the default settings of RES_DEFNAMES
2607 (qualify_single) but not RES_DNSRCH (search_parents).

2609PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2610 spool_read_header() do less string testing, by means of a preliminary
2611 switch on the second character of optional "-foo" lines. (This is
2612 overdue, caused by the large number of possibilities that now exist.
2613 Originally there were few.) While I was there, I also converted the
2614 str(n)cmp tests so they don't re-test the leading "-" and the first
2615 character, in the hope this might squeeze out yet more improvement.

2617PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2618 flag allowing group syntax was set by the header_syntax check but not
2619 turned off, possible causing trouble later; (2) The flag was not being
2620 set at all for the header_verify test, causing "group"-style headers to
2621 be rejected. I have now set it in this case, and also caused header_
2622 verify to ignore an empty address taken from a group. While doing this, I
2623 came across some other cases where the code for allowing group syntax
2624 while scanning a header line wasn't quite right (mostly, not resetting
2625 the flag correctly in the right place). These bugs could have caused
2626 trouble for malformed header lines. I hope it is now all correct.

PH
2628PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2629 with the "reply" argument non-NULL. The code, however (which originally
2630 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2631 but it didn't always do it. This confused somebody who was copying the
2632 code for some other use. I have removed all the tests.

PH
2634PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2635 feature that was used to support insecure browsers during the U.S. crypto
2636 embargo. It requires special client support, and Exim is probably the
2637 only MTA that supported it -- and would never use it because real RSA is
2638 always available. This code has been removed, because it had the bad
2639 effect of slowing Exim down by computing (never used) parameters for the
2640 RSA_EXPORT functionality.

2645 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2646 if the connection is using TLS or if the remote IP is the same as the
2647 local IP, and the "valid-client-cert option" if a client certificate has
2648 been verified.

2680PH/30 Exim was sometimes attempting to deliver messages that had suffered
2681 address errors (4xx response to RCPT) over the same connection as other
2682 messages routed to the same hosts. Such deliveries are always "forced",
2683 so retry times are not inspected. This resulted in far too many retries
2684 for the affected addresses. The effect occurred only when there were more
2685 hosts than the hosts_max_try setting in the smtp transport when it had
2686 the 4xx errors. Those hosts that it had tried were not added to the list
2687 of hosts for which the message was waiting, so if all were tried, there
2688 was no problem. Two fixes have been applied:

2690 (i) If there are any address or message errors in an SMTP delivery, none
2691 of the hosts (tried or untried) are now added to the list of hosts
2692 for which the message is waiting, so the message should not be a
2693 candidate for sending over the same connection that was used for a
2694 successful delivery of some other message. This seems entirely
2695 reasonable: after all the message is NOT "waiting for some host".
2696 This is so "obvious" that I'm not sure why it wasn't done
2697 previously. Hope I haven't missed anything, but it can't do any
2698 harm, as the worst effect is to miss an optimization.
2699
2700 (ii) If, despite (i), such a delivery is accidentally attempted, the
2701 routing retry time is respected, so at least it doesn't keep
2702 hammering the server.

2717PH/35 The error "getsockname() failed: connection reset by peer" was being
2718 written to the panic log as well as the main log, but it isn't really
2719 panic-worthy as it just means the connection died rather early on. I have
2720 removed the panic log writing for the ECONNRESET error when getsockname()
2721 fails.
2722
48c7f9e2
PH
2723PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2724 runs only) independently of the message's sender address. This meant
2725 that, if the 4xx error was in fact related to the sender, a different
2726 message to the same recipient with a different sender could confuse
4c04137d 2727 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2728 server, but other circumstances could also provoke similar problems.
2729 I have changed the default so that the retry time for these errors is now
2730 based a combination of the sender and recipient addresses. This change
2731 can be overridden by setting address_retry_include_sender=false in the
2732 smtp transport.

3004 kind of temporary error. A kludge has been added to help with this.
3005 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
3006 554 error is used if errno is still zero or contains ENOENT (which occurs
3007 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

3090PH/10 Fixed another bug related to PH/04 above: if an incoming message had a
3091 syntactically invalid From: or Reply-to: line, and a filter used this to
3092 generate an autoreply, and therefore failed to obtain an address for the
3093 autoreply, Exim could try to deliver to a non-existent relative file
3094 name, causing unrelated and misleading errors. What now happens is that
3095 it logs this as a hard delivery error, but does not attempt to create a
3096 bounce message.

3105PH/13 Domain literals for IPv6 were not recognized unless IPv6 support was
3106 compiled. In many other places in Exim, IPv6 addresses are always
3107 recognized, so I have changed this. It also means that IPv4 domain
3108 literals of the form [IPV4:n.n.n.n] are now always recognized.

3110PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
3111 used if the router is not running as root, for example, when verifying at
3112 ACL time, or when using -bh. The debugging output from this situation was
3113 non-existent - all you got was a failure to exec. I have made two
3114 changes:
3115
3116 (a) Failures to set uid/gid, the current directory, or a process leader
3117 in a subprocess such as that created by queryprogram now generate
4c04137d 3118 suitable debugging output when -d is set.
59e82a2a
PH
3119
3120 (b) The queryprogram router detects when it is not running as root,
3121 outputs suitable debugging information if -d is set, and then runs
3122 the subprocess without attempting to change uid/gid.

PH
3127PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
3128 additional section of a DNS packet that returns MX or SRV records.
3129 Instead, it always explicitly searches for A/AAAA records. This avoids
3130 major problems that occur when a DNS server includes only records of one
3131 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
3132 fixed another bug: if SRV records were looked up and the corresponding
3133 address records were *not* found in the additional section, the port
3134 values from the SRV records were lost.

PH
3136PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not
3137 using the correct key (the original address) when searching the retry
3138 rules in order to find which one to use for generating the retry hint.
3139

PH
3140PH/18 If quota_warn_message contains a From: header, Exim now refrains from
3141 adding the default one. Similarly, if it contains a Reply-To: header, the
3142 errors_reply_to option, if set, is not used.
3143
727071f8
PH
3144PH/19 When calculating a retry time, Exim used to measure the "time since
3145 failure" by looking at the "first failed" field in the retry record. Now
3146 it does not use this if it is later than than the arrival time of the
3147 message. Instead it uses the arrival time. This makes for better
3148 behaviour in cases where some deliveries succeed, thus re-setting the
3149 "first failed" field. An example is a quota failure for a huge message
3150 when small messages continue to be delivered. Without this change, the
3151 "time since failure" will always be short, possible causing more frequent
3152 delivery attempts for the huge message than are intended.

3155PH/20 Added $auth1, $auth2, $auth3 to contain authentication data (as well as

3162PH/22 Test the values given for quota, quota_filecount, quota_warn_threshold,
3163 mailbox_size, and mailbox_filecount in the appendfile transport. If a
3164 filecount value is greater than 2G or if a quota value is greater than 2G
3165 on a system where the size of off_t is not greater than 4, a panic error
3166 is given.

PH
3168PH/23 When a malformed item such as 1.2.3/24 appears in a host list, it can
3169 never match. The debug and -bh output now contains an explicit error
3170 message indicating a malformed IPv4 address or mask.
3171
3172PH/24 An host item such as 1.2.3.4/abc was being treated as the IP address
3173 1.2.3.4 without a mask. Now it is not recognized as an IP address, and
3174 PH/23 above applies.

3182PH/27 If a host name lookup failed very early in a connection, for example, if
3183 the IP address matched host_lookup and the reverse lookup yielded a name
3184 that did not have a forward lookup, an error message of the form "no IP
3185 address found for host xxx.xxx.xxx (during SMTP connection from NULL)"
3186 could be logged. Now it outputs the IP address instead of "NULL".

3191 documented for local_scan(), the new function should be too.

3205PH/33 When a queue run was abandoned because the load average was too high, a
3206 log line was always written; now it is written only if the queue_run log
3207 selector is set. In addition, the log line for abandonment now contains
3208 information about the queue run such as the pid. This is always present
3209 in "start" and "stop" lines but was omitted from the "abandon" line.

PH
3215PH/35 Change the default for dns_check_names_pattern to allow slashes within
3216 names, as there are now some PTR records that contain slashes. This check

3218 characters, so the fact that it applies to all lookups doesn't matter.

3220PH/36 Now that the new test suite is complete, we can remove some of the
3221 special code in Exim that was needed for the old test suite. For example,
3222 sorting DNS records because real resolvers return them in an arbitrary
3223 order. The new test suite's fake resolver always returns records in the
3224 same order.
3225
3226PH/37 When running in the test harness, use -odi for submitted messages (e.g.

PH
3249PH/42 The content-scanning code uses fopen() to create files in which to put
3250 message data. Previously it was not paying any attention to the mode of
3251 the files. Exim runs with umask(0) because the rest of the code creates
3252 files with open(), and sets the required mode explicitly. Thus, these
3253 files were ending up world-writeable. This was not a big issue, because,
3254 being within the spool directory, they were not world-accessible. I have
3255 created a function called modefopen, which takes an additional mode
3256 argument. It sets umask(777), creates the file, chmods it to the required
3257 mode, then resets the umask. All the relevant calls to fopen() in the
3258 content scanning code have been changed to use this function.

3268 default, the authentication attempt is cancelled if an invalid string is
3269 received. Setting client_ignore_invalid_base64 true ignores these errors.

3271 they
