|
||||
- update to 4.67
|
||||
MH/01 Fix for bug #448, segfault in Dovecot authenticator when interface_address
|
||||
is unset (happens when testing with -bh and -oMi isn't used). Thanks to
|
||||
Jan Srzednicki.
|
||||
PH/01 Added a new log selector smtp_no_mail, to log SMTP sessions that do not
|
||||
issue a MAIL command.
|
||||
PH/02 In an ACL statement such as
|
||||
deny dnslists = X!=127.0.0.2 : X=127.0.0.2
|
||||
if a client was not listed at all, or was listed with a value other than
|
||||
127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
|
||||
the condition was not true (as it should be), so access was not denied.
|
||||
The bug was that the ! inversion was incorrectly passed on to the second
|
||||
item. This has been fixed.
|
||||
PH/03 Added additional dnslists conditions == and =& which are different from
|
||||
= and & when the dns lookup returns more than one IP address.
|
||||
PH/04 Added gnutls_require_{kx,mac,protocols} to give more control over the
|
||||
cipher suites used by GnuTLS. These options are ignored by OpenSSL.
|
||||
PH/05 After discussion on the list, added a compile time option ENABLE_DISABLE_
|
||||
FSYNC, which compiles an option called disable_fsync that allows for
|
||||
bypassing fsync(). The documentation is heavily laced with warnings.
|
||||
SC/01 Updated eximstats to collate all SpamAssassin rejects into one bucket.
|
||||
PH/06 Some tidies to the infrastructure of the Test Suite that is concerned
|
||||
with the auxiliary C programs that it uses: (1) Arrange for BIND_8_COMPAT
|
||||
to be defined when compiling on OSX (Darwin); (2) Tidies to the Makefile,
|
||||
including adding "make clean"; (3) Added -fPIC when compiling the test
|
||||
dynamically loaded module, to get rid of a warning.
|
||||
MH/02 Fix for bug #451, causing paniclog entries to be written if a bounce
|
||||
message fails, move_frozen_messages = true and ignore_bounce_errors_after
|
||||
= 0s. The bug is otherwise harmless.
|
||||
PH/07 There was a bug in the dovecot authenticator such that the value of
|
||||
$auth1 could be overwritten, and so not correctly preserved, after a
|
||||
successful authentication. This usually meant that the value preserved by
|
||||
the server_setid option was incorrect.
|
||||
PH/08 Added $smtp_count_at_connection_start, deliberately with a long name.
|
||||
PH/09 Installed PCRE release 7.0.
|
||||
PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
|
||||
run for batched SMTP input. It is now run at the start of every message
|
||||
in the batch. While fixing this I discovered that the process information
|
||||
(output by running exiwhat) was not always getting set for -bs and -bS
|
||||
input. This is fixed, and it now also says "batched" for BSMTP.
|
||||
PH/11 Added control=no_pipelining.
|
||||
PH/12 Added $sending_ip_address and $sending_port (mostly Magnus Holmgren's
|
||||
patch, slightly modified), and move the expansion of helo_data till after
|
||||
the connection is made in the smtp transport (so it can use these
|
||||
values).
|
||||
PH/13 Added ${rfc2047d: to decoded RFC 2047 strings.
|
||||
PH/14 Added log_selector = +pid.
|
||||
PH/15 Flush SMTP output before delaying, unless control=no_delay_flush is set.
|
||||
PH/16 Add ${if forany and ${if forall.
|
||||
PH/17 Added dsn_from option to vary the From: line in DSNs.
|
||||
PH/18 Flush SMTP output before performing a callout, unless control =
|
||||
no_callout_flush is set.
|
||||
PH/19 Change 4.64/PH/36 introduced a bug: when address_retry_include_sender
|
||||
was true (the default) a successful delivery failed to delete the retry
|
||||
item, thus causing premature timeout of the address. The bug is now
|
||||
fixed.
|
||||
PH/20 Added hosts_avoid_pipelining to the smtp transport.
|
||||
PH/21 Long custom messages for fakedefer and fakereject are now split up
|
||||
into multiline reponses in the same way that messages for "deny" and
|
||||
other ACL rejections are.
|
||||
PH/22 Applied Jori Hamalainen's speed-up changes and typo fixes to exigrep,
|
||||
with slight modification.
|
||||
PH/23 Applied sieve patches from the maintainer "tracking the latest notify
|
||||
draft, changing the syntax and factoring some duplicate code".
|
||||
PH/24 When the log selector "outgoing_port" was set, the port was shown as -1
|
||||
for deliveries of the second and subsequent messages over the same SMTP
|
||||
connection.
|
||||
PH/25 Applied Magnus Holmgren's patch for ${addresses, ${map, ${filter, and
|
||||
${reduce, with only minor "tidies".
|
||||
SC/02 Applied Daniel Tiefnig's patch to improve the '($parent) =' pattern match.
|
||||
PH/26 Added a "continue" ACL modifier that does nothing, for the benefit of its
|
||||
expansion side effects.
|
||||
PH/27 When a message times out after an over-quota error from an Exim-imposed
|
||||
quota, the bounce message says "mailbox is full". This message was not
|
||||
being given when it was a system quota that was exceeded. It now should
|
||||
be the same.
|
||||
MH/03 Made $recipients available in local_scan(). local_scan() already has
|
||||
better access to the recipient list through recipients_list[], but
|
||||
$recipients can be useful in postmaster-provided expansion strings.
|
||||
PH/28 The $smtp_command and $smtp_command_argument variables were not correct
|
||||
in the case of a MAIL command with additional options following the
|
||||
address, for example: MAIL FROM:<foo@bar> SIZE=1234. The option settings
|
||||
were accidentally chopped off.
|
||||
PH/29 SMTP synchronization checks are implemented when a command is read -
|
||||
there is a check that no more input is waiting when there shouldn't be
|
||||
any. However, for some commands, a delay in an ACL can mean that it is
|
||||
some time before the response is written. In this time, more input might
|
||||
arrive, invalidly. So now there are extra checks after an ACL has run for
|
||||
HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
|
||||
pipelining has not been advertised.
|
||||
PH/30 MH's patch to allow iscntrl() characters to be list separators.
|
||||
PH/31 Unlike :fail:, a custom message specified with :defer: was not being
|
||||
returned in the SMTP response when smtp_return_error_details was false.
|
||||
This has been fixed.
|
||||
PH/32 Change the Dovecot authenticator to use read() and write() on the socket
|
||||
instead of the C I/O that was originally supplied, because problems were
|
||||
reported on Solaris.
|
||||
PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
|
||||
Exim which did not show up earlier: it was assuming that a call to
|
||||
SSL_CTX_set_info_callback() might give an error value. In fact, there is
|
||||
no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
|
||||
was a macro that became an assignment, so it seemed to work. This has
|
||||
changed to a proper function call with a void return, hence the compile
|
||||
error. Exim's code has been fixed.
|
||||
PH/34 Change HDA_SIZE in oracle.c from 256 to 512. This is needed for 64-bit
|
||||
cpus.
|
||||
PH/35 Applied a patch from the Sieve maintainer which fixes a bug in "notify".
|
||||
PH/36 Applied John Jetmore's patch to add -v functionality to exigrep.
|
||||
PH/37 If a message is not accepted after it has had an id assigned (e.g.
|
||||
because it turns out to be too big or there is a timeout) there is no
|
||||
"Completed" line in the log. When some messages of this type were
|
||||
selected by exigrep, they were listed as "not completed". Others were
|
||||
picked up by some special patterns. I have improved the selection
|
||||
criteria to be more general.
|
||||
PH/38 The host_find_failed option in the manualroute router can now be set
|
||||
to "ignore", to completely ignore a host whose IP address cannot be
|
||||
found. If all hosts are ignored, the behaviour is controlled by the new
|
||||
host_all_ignored option.
|
||||
PH/39 In a list of hosts for manualroute, if one item (either because of multi-
|
||||
homing or because of multiple MX records with /mx) generated more than
|
||||
one IP address, and the following item turned out to be the local host,
|
||||
all the secondary addresses of the first item were incorrectly removed
|
||||
from the list, along with the local host and any following hosts (which
|
||||
is what is supposed to happen).
|
||||
PH/40 When Exim receives a message, it writes the login name, uid, and gid of
|
||||
whoever called Exim into the -H file. In the case of the daemon it was
|
||||
behaving confusingly. When first started, it used values for whoever
|
||||
started the daemon, but after a SIGHUP it used the Exim user (because it
|
||||
calls itself on a restart). I have changed the code so that it now always
|
||||
uses the Exim user.
|
||||
PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
|
||||
message are rejected with the same error (e.g. no authentication or bad
|
||||
sender address), and a DATA command is nevertheless sent (as can happen
|
||||
with PIPELINING or a stupid MUA), the error message that was given to the
|
||||
RCPT commands is included in the rejection of the DATA command. This is
|
||||
intended to be helpful for MUAs that show only the final error to their
|
||||
users.
|
||||
PH/42 Another patch from the Sieve maintainer.
|
||||
SC/02 Eximstats - Differentiate between permanent and temporary rejects.
|
||||
Eximstats - Fixed some broken HTML links and added missing column headers
|
||||
(Jez Hancock).
|
||||
Eximstats - Fixed Grand Total Summary Domains, Edomains, and Email
|
||||
columns for Rejects, Temp Rejects, Ham, and Spam rows.
|
||||
SC/03 Eximstats - V1.58 Fix to get <> and blackhole to show in edomain tables.
|
||||
PH/43 Yet another patch from the Sieve maintainer.
|
||||
PH/44 I found a way to check for a TCP/IP connection going away before sending
|
||||
the response to the final '.' that terminates a message, but only in the
|
||||
case where the client has not sent further data following the '.'
|
||||
(unfortunately, this is allowed). However, in many cases there won't be
|
||||
any further data because there won't be any more messages to send. A call
|
||||
to select() can be used: if it shows that the input is "ready", there is
|
||||
either input waiting, or the socket has been closed. An attempt to read
|
||||
the next input character can distinguish the two cases. Previously, Exim
|
||||
would have sent an OK response which the client would never have see.
|
||||
This could lead to message repetition. This fix should cure that, at
|
||||
least in a lot of common cases.
|
||||
PH/45 Do not advertise STARTTLS in response to HELP unless it would be
|
||||
advertised in response to EHLO.
