Change log file for Exim from version 4.21
-------------------------------------------
+Exim version 4.64
+-----------------
+
+TF/01 In the add_headers option to the mail command in an Exim filter,
+ there was a bug that Exim would claim a syntax error in any
+ header after the first one which had an odd number of characters
+ in the field name.
+
+PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
+ callout verification, Exim cached a "reject" for the entire domain. This
+ is correct for most verifications, but it is not correct for a recipient
+ verification with use_sender or use_postmaster set, because in that case
+ the callout does not use MAIL FROM:<>. Exim now distinguishes the special
+ case of MAIL FROM:<> rejection from other early rejections (e.g.
+ rejection of HELO). When verifying a recipient using a non-null MAIL
+ address, the cache is ignored if it shows MAIL FROM:<> rejection.
+ Whatever the result of the callout, the value of the domain cache is
+ left unchanged (for any other kind of callout, getting as far as trying
+ RCPT means that the domain itself is ok).
+
+PH/02 Tidied a number of unused variable and signed/unsigned warnings that
+ gcc 4.1.1 threw up.
+
+PH/03 On Solaris, an unexpectedly close socket (dropped connection) can
+ manifest itself as EPIPE rather than ECONNECT. When tidying away a
+ session, the daemon ignores ECONNECT errors and logs others; it now
+ ignores EPIPE as well.
+
+PH/04 Applied Nico Erfurth's refactoring patch to tidy up mime.c
+ (quoted-printable decoding).
+
+PH/05 Applied Nico Erfurth's refactoring patch to tidy up spool_mbox.c, and
+ later the small subsequent patch to fix an introduced bug.
+
+PH/06 Installed the latest Cygwin Makefile from the Cygwin maintainer.
+
+PH/07 There was no check for overflow in expansions such as ${if >{1}{4096M}}.
+
+PH/08 An error is now given if message_size_limit is specified negative.
+
+PH/09 Applied and tidied up Jakob Hirsch's patch for allowing ACL variables
+ to be given (somewhat) arbitrary names.
+
+JJ/01 exipick 20060919.0, allow for arbitrary acl_ variables introduced
+ in 4.64-PH/09.
+
+JJ/02 exipick 20060919.0, --show-vars args can now be regular expressions,
+ miscellaneous code fixes
+
+PH/10 Added the log_reject_target ACL modifier to specify where to log
+ rejections.
+
+PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
+ hostname. This is wrong, because it relates to the incoming message (and
+ probably the interface on which it is arriving) and not to the outgoing
+ callout (which could be using a different interface). This has been
+ changed to use the value of the helo_data option from the smtp transport
+ instead - this is what is used when a message is actually being sent. If
+ there is no remote transport (possible with a router that sets up host
+ addresses), $smtp_active_hostname is used.
+
+PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
+ tweaks were necessary in order to get it to work:
+ (a) The code assumed that strncpy() returns a negative number on buffer
+ overflow, which isn't the case. Replaced with Exim's string_format()
+ function.
+ (b) There were several signed/unsigned issues. I just did the minimum
+ hacking in of casts. There is scope for a larger refactoring.
+ (c) The code used strcasecmp() which is not a standard C function.
+ Replaced with Exim's strcmpic() function.
+ (d) The code set only $1; it now sets $auth1 as well.
+ (e) A simple test gave the error "authentication client didn't specify
+ service in request". It would seem that Dovecot has changed its
+ interface. Fortunately there's a specification; I followed it and
+ changed what the client sends and it appears to be working now.
+
+
Exim version 4.63
-----------------
TF/01 Correct an error in the documentation for the redirect router. Exim
does (usually) call initgroups() when daemonizing.
-TF/02 Call initgroups() when dropping privilege in exim.c, so that Exim runs with
- consistent privilege compared to when running as a daemon.
+TF/02 Call initgroups() when dropping privilege in exim.c, so that Exim runs
+ with consistent privilege compared to when running as a daemon.
TF/03 Note in the spec that $authenticated_id is not set for local
submissions from trusted users.
directory not expanded when it should be if an expanded home directory
was set for the address (which is overridden by the transport).
+PH/05 Applied Alex Kiernan's patch to fix Bugzilla #99: a problem with
+ libradius.
+
+PH/06 Added acl_not_smtp_start, based on Johannes Berg's patch, and set the
+ bit to forbid control=suppress_local_fixups in the acl_not_smtp ACL,
+ because it is too late at that time, and has no effect.
+
+PH/07 Changed ${quote_pgsql to quote ' as '' instead of \' because of a
+ security issue with \' (bugzilla #107). I could not use the
+ PQescapeStringConn() function, because it needs a PGconn value as one of
+ its arguments.
+
+PH/08 When testing addresses using -bt, indicate those final addresses that
+ are duplicates that would not cause an additional delivery. At least one
+ person was confused, thinking that -bt output corresponded to deliveries.
+ (Suppressing duplicates isn't a good idea as you lose the information
+ about possibly different redirections that led to the duplicates.)
+
+PH/09 Applied patch from Erik to use select() instead of poll() in spam.c on
+ systems where poll() doesn't work, in particular OS X.
+
+PH/10 Added more information to debugging output for retry time not reached.
+
+PH/11 Applied patch from Arkadiusz Miskiewicz to apply a timeout to read
+ operations in malware.c.
+
+PH/12 Applied patch from Magnus Holmgren to include the "h" tag in Domain Keys
+ signatures.
+
+PH/13 If write_rejectlog was set false when logging was sent to syslog with
+ syslog_duplication set false, log lines that would normally be written
+ both the the main log and to the reject log were not written to syslog at
+ all.
+
+PH/14 In the default configuration, change the use of "message" in ACL warn
+ statements to "add_header".
+
+PH/15 Diagnose a filter syntax error for "seen", "unseen", or "noerror" if not
+ not followed by a command (e.g. "seen endif").
+
+PH/16 Recognize SMTP codes at the start of "message" in ACLs and after :fail:
+ and :defer: in a redirect router. Add forbid_smtp_code to suppress the
+ latter.
+
+PH/17 Added extra conditions to the default value of delay_warning_condition
+ so that it is now:
+
+ ${if or { \
+ { !eq{$h_list-id:$h_list-post:$h_list-subscribe:}{} } \
+ { match{$h_precedence:}{(?i)bulk|list|junk} } \
+ { match{$h_auto-submitted:}{(?i)auto-generated|auto-replied} } \
+ }{no}{yes}}
+
+ The Auto-Submitted: and various List- headers are standardised, whereas I
+ don't think Precedence: ever was.
+
+PH/18 Refactored debugging code in route_finduser() to show more information,
+ in particular, the error code if getpwnam() issues one.
+
+PH/19 Added PQsetClientEncoding(conn, "SQL_ASCII") to the pgsql code module.
+ This is apparently needed in addition to the PH/07 change above to avoid
+ any possible encoding problems.
+
+PH/20 Perl can change the locale. Exim was resetting it after a ${perl call,
+ but not after initializing Perl.
+
+PH/21 Added a call to PQsetNoticeProcessor() to catch pgsql "notices" and
+ output them only if debugging. By default they are written stderr,
+ apparently, which is not desirable.
+
+PH/22 Added Alain Williams' LDAP patch to support setting REFERRALS=off on
+ queries.
+
+JJ/01 exipick: added --reverse (and -R synonym), --random, --size, --sort and
+ --not options
+
+JJ/02 exipick: rewrote --help documentation to hopefully make more clear.
+
+PH/23 Made -oMaa and -oMt work with -bh and -bs to pretend the connection is
+ authenticated or an ident call has been made. Suppress the default
+ values for $authenticated_id and $authenticated_sender (but permit -oMai
+ and -oMas) when testing with -bh.
+
+PH/24 Re-jigged the order of the tests in the default configuration so that the
+ tests for valid domains and recipients precede the DNS black list and CSA
+ tests, on the grounds that those ones are more expensive.
+
+PH/25 Exim was not testing for a space following SMTP commands such as EHLO
+ that require one. Thus, EHLORHUBARB was interpreted as a valid command.
+ This bug exists in every version of Exim that I still have, right back to
+ 0.12.
+
+PH/26 (n)wildlsearch lookups are documented as being done case-insensitively.
+ However, an attempt to turn on case-sensitivity in a regex key by
+ including (?-i) didn't work because the subject string was already
+ lowercased, and the effects were non-intuitive. It turns out that a
+ one-line patch can be used to allow (?-i) to work as expected.
