11JH/01 Replace the store_release() internal interface with store_newblock(),
12 which internalises the check required to safely use the old one, plus

22JH/04 Bug 2217: Tighten up the parsing of DKIM signature headers. Previously
23 we assumed that tags in the header were well-formed, and parsed the
24 element content after inspecting only the first char of the tag.
25 Assumptions at that stage could crash the receive process on malformed
26 input.

28JH/05 Bug 2215: Fix crash associated with dnsdb lookup done from DKIM ACL.
29 While running the DKIM ACL we operate on the Permanent memory pool so that
30 variables created with "set" persist to the DATA ACL. Also (at any time)
31 DNS lookups that fail create cache records using the Permanent pool. But
32 expansions release any allocations made on the current pool - so a dnsdb
33 lookup expansion done in the DKIM ACL releases the memory used for the
34 DNS negative-cache, and bad things result. Solution is to switch to the
35 Main pool for expansions.
36 While we're in that code, add checks on the DNS cache during store_reset,
37 active in the testsuite.
38 Problem spotted, and debugging aided, by Wolfgang Breyha.

40JH/06 Fix issue with continued-connections when the DNS shifts unreliably.
41 When none of the hosts presented to a transport match an already-open
42 connection, close it and proceed with the list. Previously we would
43 queue the message. Spotted by Lena with Yahoo, probably involving
44 round-robin DNS.

67 multiple onward connections in sequence, handling cutthrough connection
68 for all multi-message initiating connections.

72-----------------

74JH/01 Rework error string handling in TLS interface so that the caller in
75 more cases is responsible for logging. This permits library-sourced
76 string to be attached to addresses during delivery, and collapses
77 pairs of long lines into single ones.

84

JH
85JH/03 Rework the transport continued-connection mechanism: when TLS is active,
86 do not close it down and have the child transport start it up again on
87 the passed-on TCP connection. Instead, proxy the child (and any
88 subsequent ones) for TLS via a unix-domain socket channel. Logging is
89 affected: the continued delivery log lines do not have any DNSSEC, TLS
5013d912 90 Certificate or OCSP information. TLS cipher information is still logged.

102
7006ee24
JH
103JH/06 Default openssl_options to include +no_ticket, to reduce load on peers.
104 Disable the session-cache too, which might reduce our load. Since we
105 currrectly use a new context for every connection, both as server and
106 client, there is no benefit for these.
107 GnuTLS appears to not support tickets server-side by default (we don't
108 call gnutls_session_ticket_enable_server()) but client side is enabled
109 by default on recent versions (3.1.3 +) unless the PFS priority string
110 is used (3.2.4 +).

115JH/07 Fix smtp transport use of limited max_rcpt under mua_wrapper. Previously
116 the check for any unsuccessful recipients did not notice the limit, and
117 erroneously found still-pending ones.

JH
122JH/09 Avoid using a temporary file during transport using dkim. Unless a
123 transport-filter is involved we can buffer the headers in memory for
124 creating the signature, and read the spool data file once for the
125 signature and again for transmission.
126

JH
127JH/10 Enable use of sendfile in Linux builds as default. It was disabled in
128 4.77 as the kernel support then wasn't solid, having issues in 64bit
7d758a6a 129 mode. Now, it's been long enough. Add support for FreeBSD also.

131JH/11 Bug 2104: Fix continued use of a transport connection with TLS. In the
132 case where the routing stage had gathered several addresses to send to
133 a host before calling the transport for the first, we previously failed
134 to close down TLS in the old transport process before passing the TCP
135 connection to the new process. The new one sent a STARTTLS command
136 which naturally failed, giving a failed delivery and bloating the retry
137 database. Investigation and fix prototype from Wolfgang Breyha.
138
40525d07
JH
139JH/12 Fix check on SMTP command input synchronisation. Previously there were
140 false-negatives in the check that the sender had not preempted a response
141 or prompt from Exim (running as a server), due to that code's lack of
a5ffa9b4 142 awareness of the SMTP input buffering.
40525d07 143
f33875c3
PP
144PP/04 Add commandline_checks_require_admin option.
145 Exim drops privileges sanely, various checks such as -be aren't a
146 security problem, as long as you trust local users with access to their
147 own account. When invoked by services which pass untrusted data to
148 Exim, this might be an issue. Set this option in main configuration
149 AND make fixes to the calling application, such as using `--` to stop
150 processing options.
151
a5ffa9b4
JH
152JH/13 Do pipelining under TLS. Previously, although safe, no advantage was
153 taken. Now take care to pack both (client) MAIL,RCPT,DATA, and (server)
154 responses to those, into a single TLS record each way (this usually means
155 a single packet). As a side issue, smtp_enforce_sync now works on TLS
156 connections.

392JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
393 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
394 or even an in-clear connection were permitted. Now, if the host lookup
395 was dnssec and dane was requested then the host is only used if the
396 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
397 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
398 if one fails this test.
399 This means that a poorly-configured remote DNS will make it incommunicado;
400 but it protects against a DNS-interception attack on it.

1214TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
1215
1216 When a queue runner is handling a message, Exim first routes the
1217 recipient addresses, during which it prunes them based on the retry
1218 hints database. After that it attempts to deliver the message to
1219 any remaining recipients. It then updates the hints database using
1220 the retry rules.
1221
1222 So if a recipient address works intermittently, it can get repeatedly
1223 deferred at routing time. The retry hints record remains fresh so the
1224 address never reaches the final cutoff time.
1225
1226 This is a fairly common occurrence when a user is bumping up against
1227 their storage quota. Exim had some logic in its local delivery code
1228 to deal with this. However it did not apply to per-recipient defers
1229 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1230
1ddeb334
TF
1231 This change adds a proper retry rule check during routing so that the
1232 final cutoff time is checked against the message's age. We only do
1233 this check if there is an address retry record and there is not a
1234 domain retry record; this implies that previous attempts to handle
1235 the address had the retry_use_local_parts option turned on. We use
1236 this as an approximation for the destination being like a local
1237 delivery, as in LMTP.
67bd1ab3
TF
1238
1239 I suspect this new check makes the old local delivery cutoff check
1240 redundant, but I have not verified this so I left the code in place.

1248 When I ran the test suite under the user fanf2, Exim expanded
1249 the header to contain my full name, whereas it should have added
1250 a Resent-Sender: header. It erroneously treats any prefix of the
1251 username as equal to the username.

1562TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1563 lock up or crash if it happened to be inside a call to libc when it
1564 got a SIGUSR1 from exiwhat.
1565
1566 The SIGUSR1 handler appends the current process status to the process
1567 log which is later printed by exiwhat. It used to use the general
1568 purpose logging code to do this, but several functions it calls are
1569 not safe for signals.
1570
1571 The new output code in the SIGUSR1 handler is specific to the process
1572 log, and simple enough that it's easy to inspect for signal safety.
1573 Removing some special cases also simplifies the general logging code.
1574 Removing the spurious timestamps from the process log simplifies
1575 exiwhat.

1577TF/04 Improved ratelimit ACL condition.
1578
1579 The /noupdate option has been deprecated in favour of /readonly which
1580 has clearer semantics. The /leaky, /strict, and /readonly update modes
1581 are mutually exclusive. The update mode is no longer included in the
1582 database key; it just determines when the database is updated. (This
4c04137d 1583 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1584
1585 Exim now checks that the per_* options are used with an update mode that
1586 makes sense for the current ACL. For example, when Exim is processing a
1587 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1588 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1589 must specify per_mail/readonly. If you omit the update mode it defaults to
1590 /leaky where that makes sense (as before) or /readonly where required.
1591
1592 The /noupdate option is now undocumented but still supported for
1593 backwards compatibility. It is equivalent to /readonly except that in
1594 ACLs where /readonly is required you may specify /leaky/noupdate or
1595 /strict/noupdate which are treated the same as /readonly.
1596
1597 A useful new feature is the /count= option. This is a generalization
1598 of the per_byte option, so that you can measure the throughput of other
1599 aggregate values. For example, the per_byte option is now equivalent
1600 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1601
1602 The per_rcpt option has been generalized using the /count= mechanism
1603 (though it's more complicated than the per_byte equivalence). When it is
1604 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1605 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1606 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1607 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1608 Note that using per_rcpt with a non-readonly update mode in more than
1609 one ACL will cause the recipients to be double-counted. (The per_mail
1610 and per_byte options don't have this problem.)
1611
1612 The handling of very low rates has changed slightly. If the computed rate
1613 is less than the event's count (usually one) then this event is the first
1614 after a long gap. In this case the rate is set to the same as this event's
1615 count, so that the first message of a spam run is counted properly.
1616
1617 The major new feature is a mechanism for counting the rate of unique
1618 events. The new per_addr option counts the number of different
1619 recipients that someone has sent messages to in the last time period. It
1620 behaves like per_rcpt if all the recipient addresses are different, but
1621 duplicate recipient addresses do not increase the measured rate. Like
1622 the /count= option this is a general mechanism, so the per_addr option
1623 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1624 example, measure the rate that a client uses different sender addresses
1625 with the options per_mail/unique=$sender_address. There are further
1626 details in the main documentation.

2198PH/01 Another patch from the Sieve maintainer.
2199
6a3bceb1
PH
2200PH/02 When an IPv6 address is converted to a string for single-key lookup
2201 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
2202 dots are used instead of colons so that keys in lsearch files need not
2203 contain colons. This was done some time before quoting was made available
2204 in lsearch files. However, iplsearch files do require colons in IPv6 keys
2205 (notated using the quote facility) so as to distinguish them from IPv4
2206 keys. This meant that lookups for IP addresses in host lists did not work
2207 for iplsearch lookups.
2208
2209 This has been fixed by arranging for IPv6 addresses to be expressed with
2210 colons if the lookup type is iplsearch. This is not incompatible, because
2211 previously such lookups could never work.
2212
4c04137d 2213 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2214 ordinary lsearch keys. However, making the change in all cases is
2215 incompatible and would probably break a number of configurations.

2220MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2221 conversion specification without a maximum field width, thereby enabling
2222 a rogue spamd server to cause a buffer overflow. While nobody in their
2223 right mind would setup Exim to query an untrusted spamd server, an
2224 attacker that gains access to a server running spamd could potentially
2225 exploit this vulnerability to run arbitrary code as the Exim user.

MH
2230MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2231 a directory entry by the name of the lookup key. Previously, if a
2232 symlink pointed to a non-existing file or a file in a directory that
2233 Exim lacked permissions to read, a lookup for a key matching that
2234 symlink would fail. Now it is enough that a matching directory entry
2235 exists, symlink or not. (Bugzilla 503.)

2418PH/29 SMTP synchronization checks are implemented when a command is read -
2419 there is a check that no more input is waiting when there shouldn't be
2420 any. However, for some commands, a delay in an ACL can mean that it is
2421 some time before the response is written. In this time, more input might
2422 arrive, invalidly. So now there are extra checks after an ACL has run for
2423 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2424 pipelining has not been advertised.

PH
2498 the response to the final '.' that terminates a message, but only in the
2499 case where the client has not sent further data following the '.'
2500 (unfortunately, this is allowed). However, in many cases there won't be
2501 any further data because there won't be any more messages to send. A call
2502 to select() can be used: if it shows that the input is "ready", there is
2503 either input waiting, or the socket has been closed. An attempt to read
2504 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2505 would have sent an OK response which the client would never have see.

2516PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2517 fixed by 4.65/MH/01 (is this a record?) are fixed:
2518
2519 (i) An empty string was always treated as zero by the numeric comparison
2520 operators. This behaviour has been restored.
2521
2522 (ii) It is documented that the numeric comparison operators always treat
2523 their arguments as decimal numbers. This was broken in that numbers
2524 starting with 0 were being interpreted as octal.
2525
2526 While fixing these problems I realized that there was another issue that
2527 hadn't been noticed. Values of message_size_limit (both the global option
2528 and the transport option) were treated as octal if they started with 0.
2529 The documentation was vague. These values are now always treated as
2530 decimal, and I will make that clear in the documentation.

2546 is held in a short int, deliveries were likely to be lost. As such a
2547 large number of recipients for a single message is ridiculous
2548 (performance will be very, very poor), I have chosen to impose a limit
2549 rather than extend the field.

2556 leftover -K file (the existence of which was triggered by #402).

2b1c6e3a
PH
2574PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2575 callout verification, Exim cached a "reject" for the entire domain. This
2576 is correct for most verifications, but it is not correct for a recipient
2577 verification with use_sender or use_postmaster set, because in that case
2578 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2579 case of MAIL FROM:<> rejection from other early rejections (e.g.
2580 rejection of HELO). When verifying a recipient using a non-null MAIL
2581 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2582 Whatever the result of the callout, the value of the domain cache is
2583 left unchanged (for any other kind of callout, getting as far as trying
2584 RCPT means that the domain itself is ok).

2618PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2620 probably the interface on which it is arriving) and not to the outgoing
2621 callout (which could be using a different interface). This has been
2622 changed to use the value of the helo_data option from the smtp transport
2623 instead - this is what is used when a message is actually being sent. If
2624 there is no remote transport (possible with a router that sets up host
2625 addresses), $smtp_active_hostname is used.

7befa435 2628 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2629 (a) The code assumed that strncpy() returns a negative number on buffer
2630 overflow, which isn't the case. Replaced with Exim's string_format()
2631 function.
2632 (b) There were several signed/unsigned issues. I just did the minimum
2633 hacking in of casts. There is scope for a larger refactoring.
2634 (c) The code used strcasecmp() which is not a standard C function.
2635 Replaced with Exim's strcmpic() function.
2636 (d) The code set only $1; it now sets $auth1 as well.
2637 (e) A simple test gave the error "authentication client didn't specify
2638 service in request". It would seem that Dovecot has changed its
2639 interface. Fortunately there's a specification; I followed it and
2640 changed what the client sends and it appears to be working now.

2646 address A is aliased to B and C, where B exists and C does not. Without
2647 -v the output is "A verified" because verification stops after a
2648 successful redirection if more than one address is generated. However,
2649 with -v the child addresses are also verified. Exim was outputting "A
2650 failed to verify" and then showing the successful verification for C,
2651 with its parentage. It now outputs "B failed to verify", showing B's
2652 parentage before showing the successful verification of C.

PH
2658PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2659 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2660 they consult the DNS. I had assumed they would set it the way they
2661 wanted; and indeed my experiments on Linux seem to show that in some
2662 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2663 To be on the safe side, however, I have now made the interface to
2664 host_find_byname() similar to host_find_bydns(), with an argument
2665 containing the DNS resolver options. The host_find_byname() function now
2666 sets these options at its start, just as host_find_bydns() does. The smtp
2667 transport options dns_qualify_single and dns_search_parents are passed to
2668 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2669 of host_find_byname() use the default settings of RES_DEFNAMES
2670 (qualify_single) but not RES_DNSRCH (search_parents).

2673 spool_read_header() do less string testing, by means of a preliminary
2674 switch on the second character of optional "-foo" lines. (This is
2675 overdue, caused by the large number of possibilities that now exist.
2676 Originally there were few.) While I was there, I also converted the
2677 str(n)cmp tests so they don't re-test the leading "-" and the first
2678 character, in the hope this might squeeze out yet more improvement.

2680PH/18 Two problems with "group" syntax in header lines when verifying: (1) The

2683 set at all for the header_verify test, causing "group"-style headers to
2684 be rejected. I have now set it in this case, and also caused header_
2685 verify to ignore an empty address taken from a group. While doing this, I
2686 came across some other cases where the code for allowing group syntax
2687 while scanning a header line wasn't quite right (mostly, not resetting
2688 the flag correctly in the right place). These bugs could have caused
2689 trouble for malformed header lines. I hope it is now all correct.

2693 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2694 but it didn't always do it. This confused somebody who was copying the
2695 code for some other use. I have removed all the tests.

PH
2697PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2698 feature that was used to support insecure browsers during the U.S. crypto
2699 embargo. It requires special client support, and Exim is probably the
2700 only MTA that supported it -- and would never use it because real RSA is
2701 always available. This code has been removed, because it had the bad
2702 effect of slowing Exim down by computing (never used) parameters for the
2703 RSA_EXPORT functionality.

2705PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2706 authenticator to fail if there's a tab character in the incoming data
2707 (there should never be unless someone is messing about, as it's supposed
2708 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2709 if the connection is using TLS or if the remote IP is the same as the
2710 local IP, and the "valid-client-cert option" if a client certificate has
2711 been verified.

PH
2742
2743PH/30 Exim was sometimes attempting to deliver messages that had suffered
2744 address errors (4xx response to RCPT) over the same connection as other
2745 messages routed to the same hosts. Such deliveries are always "forced",
2746 so retry times are not inspected. This resulted in far too many retries
2747 for the affected addresses. The effect occurred only when there were more
2748 hosts than the hosts_max_try setting in the smtp transport when it had
2749 the 4xx errors. Those hosts that it had tried were not added to the list
2750 of hosts for which the message was waiting, so if all were tried, there
2751 was no problem. Two fixes have been applied:
2752
2753 (i) If there are any address or message errors in an SMTP delivery, none
2754 of the hosts (tried or untried) are now added to the list of hosts
2755 for which the message is waiting, so the message should not be a
2756 candidate for sending over the same connection that was used for a
2757 successful delivery of some other message. This seems entirely
2758 reasonable: after all the message is NOT "waiting for some host".
2759 This is so "obvious" that I'm not sure why it wasn't done
2760 previously. Hope I haven't missed anything, but it can't do any
2761 harm, as the worst effect is to miss an optimization.
2762
2763 (ii) If, despite (i), such a delivery is accidentally attempted, the
2764 routing retry time is respected, so at least it doesn't keep
2765 hammering the server.

2780PH/35 The error "getsockname() failed: connection reset by peer" was being
2781 written to the panic log as well as the main log, but it isn't really
2782 panic-worthy as it just means the connection died rather early on. I have
2783 removed the panic log writing for the ECONNRESET error when getsockname()
2784 fails.
2785
48c7f9e2
PH
2786PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2787 runs only) independently of the message's sender address. This meant
2788 that, if the 4xx error was in fact related to the sender, a different
2789 message to the same recipient with a different sender could confuse
4c04137d 2790 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2791 server, but other circumstances could also provoke similar problems.
2792 I have changed the default so that the retry time for these errors is now
2793 based a combination of the sender and recipient addresses. This change
2794 can be overridden by setting address_retry_include_sender=false in the
2795 smtp transport.

3068 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
3069 554 error is used if errno is still zero or contains ENOENT (which occurs

3080 addresses were routed directly to files or pipes from a redirect router.
3081 File deliveries just didn't batch; pipe deliveries might have suffered
3082 odd errors.

3087PH/07 The appendfile transport was creating MBX lock files with a fixed mode

3093PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
3094 folder from quota calculations, a direct delivery into this folder messed
3095 up the contents of the maildirsize file. This was because the regex was
3096 used only to exclude .Trash (or whatever) when the size of the mailbox
3097 was calculated. There was no check that a delivery was happening into an
3098 excluded directory. This bug has been fixed by ignoring all quota
3099 processing for deliveries into excluded directories.

3104Exim version 4.61
3105-----------------
3106
3107PH/01 The code for finding all the local interface addresses on a FreeBSD
3108 system running IPv6 was broken. This may well have applied to all BSD
3109 systems, as well as to others that have similar system calls. The broken
3110 code found IPv4 interfaces correctly, but gave incorrect values for the
3111 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
3112 that it would not match correctly against @[] and not recognize the IPv6
3113 addresses as local.

3120PH/04 Changed $reply_address to use the raw form of the headers instead of the
3121 decoded form, because it is most often used to construct To: headers
3122 lines in autoreplies, and the decoded form may well be syntactically
3123 invalid. However, $reply_address has leading white space removed, and all
3124 newlines turned into spaces so that the autoreply transport does not
3125 grumble.

3133 spool files has been maintained. However, going back to a previous Exim
3134 release will lost any variables that are in spool files.

3153PH/10 Fixed another bug related to PH/04 above: if an incoming message had a
3154 syntactically invalid From: or Reply-to: line, and a filter used this to
3155 generate an autoreply, and therefore failed to obtain an address for the
3156 autoreply, Exim could try to deliver to a non-existent relative file
3157 name, causing unrelated and misleading errors. What now happens is that
3158 it logs this as a hard delivery error, but does not attempt to create a
3159 bounce message.

3168PH/13 Domain literals for IPv6 were not recognized unless IPv6 support was
3169 compiled. In many other places in Exim, IPv6 addresses are always

3171 literals of the form [IPV4:n.n.n.n] are now always recognized.

3173PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
3174 used if the router is not running as root, for example, when verifying at
3175 ACL time, or when using -bh. The debugging output from this situation was
3176 non-existent - all you got was a failure to exec. I have made two
3177 changes:
3178
3179 (a) Failures to set uid/gid, the current directory, or a process leader
3180 in a subprocess such as that created by queryprogram now generate
4c04137d 3181 suitable debugging output when -d is set.
59e82a2a
PH
3182
3183 (b) The queryprogram router detects when it is not running as root,
3184 outputs suitable debugging information if -d is set, and then runs
3185 the subprocess without attempting to change uid/gid.

3190PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
3191 additional section of a DNS packet that returns MX or SRV records.
3192 Instead, it always explicitly searches for A/AAAA records. This avoids
3193 major problems that occur when a DNS server includes only records of one
3194 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
3195 fixed another bug: if SRV records were looked up and the corresponding
3196 address records were *not* found in the additional section, the port
3197 values from the SRV records were lost.

3199PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

3201 rules in order to find which one to use for generating the retry hint.

PH
3203PH/18 If quota_warn_message contains a From: header, Exim now refrains from
3204 adding the default one. Similarly, if it contains a Reply-To: header, the
3205 errors_reply_to option, if set, is not used.
3206

PH
3207PH/19 When calculating a retry time, Exim used to measure the "time since
3208 failure" by looking at the "first failed" field in the retry record. Now
3209 it does not use this if it is later than than the arrival time of the
3210 message. Instead it uses the arrival time. This makes for better
3211 behaviour in cases where some deliveries succeed, thus re-setting the
3212 "first failed" field. An example is a quota failure for a huge message
3213 when small messages continue to be delivered. Without this change, the
3214 "time since failure" will always be short, possible causing more frequent
3215 delivery attempts for the huge message than are intended.

3229 is given.

3234
3235PH/24 An host item such as 1.2.3.4/abc was being treated as the IP address
