Change log file for Exim from version 4.21
-------------------------------------------
+Exim version 4.63
+-----------------
+
+SC/01 Use a glob alias rather than an array ref in eximstats generated
+ parser. This improves both readability and performance.
+
+SC/02 Collect SpamAssassin and rejection statistics in eximstats.
+ Don't display local sender or destination tables in eximstats unless
+ there is data to show.
+ Added average volumes into the eximstats top table text output.
+
+SC/03 Collect data on the number of addresses (recipients) as well
+ as the number of messages in eximstats.
+
+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/03 Note in the spec that $authenticated_id is not set for local
+ submissions from trusted users.
+
+TF/04 The ratelimit per_rcpt option now works correctly in acl_not_smtp.
+ Thanks to Dean Brooks <dean@iglou.com> for the patch.
+
+TF/05 Make it easier to get SMTP authentication and TLS/SSL support working
+ by adding some example configuration directives to the default
+ configuration file. A little bit of work is required to uncomment the
+ directives and define how usernames and passwords are checked, but
+ there is now a framework to start from.
+
+PH/01 Added #define LDAP_DEPRECATED 1 to ldap.c because some of the "old"
+ functions that Exim currently uses aren't defined in ldap.h for OpenLDAP
+ without this. I don't know how relevant this is to other LDAP libraries.
+
+PH/02 Add the verb name to the "unknown ACL verb" error.
+
+PH/03 Magnus Holmgren's patch for filter_prepend_home.
+
+PH/03 Fixed Bugzilla #101: macro definition between ACLs doesn't work.
+
+PH/04 Applied Magnus Holmgren's patch to fix Bugzilla #98: transport's home
+ 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.
+
+
+Exim version 4.62
+-----------------
+
+TF/01 Fix the add_header change below (4.61 PH/55) which had a bug that (amongst
+ other effects) broke the use of negated acl sub-conditions.
+
+PH/01 ${readsocket now supports Internet domain sockets (modified John Jetmore
+ patch).
+
+PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
+ "Deny" causes Exim to reject the incoming connection with a 554 error.
+ Unfortunately, if there is a major crisis, such as a disk failure,
+ tcp-wrappers gives "deny", whereas what one would like would be some
+ kind of temporary error. A kludge has been added to help with this.
+ Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
+ 554 error is used if errno is still zero or contains ENOENT (which occurs
+ if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
+ 451 error is used.
+
+PH/03 Add -lutil to the default FreeBSD LIBS setting.
+
+PH/04 Change PH/19 for 4.61 was too wide. It should not be applied to host
+ errors. Otherwise a message that provokes a temporary error (when other
+ messages do not) can cause a whole host to time out.
+
+PH/05 Batch deliveries by appendfile and pipe transports did not work when the
+ addresses were routed directly to files or pipes from a redirect router.
+ File deliveries just didn't batch; pipe deliveries might have suffered
+ odd errors.
+
+PH/06 A failure to get a lock for a hints database would erroneously always say
+ "Failed to get write lock", even when it was really a read lock.
+
+PH/07 The appendfile transport was creating MBX lock files with a fixed mode
+ of 0600. This has been changed to use the value of the lockfile_mode
+ option (which defaults to 0600).
+
+PH/08 Applied small patch from the Sieve maintainer.
+
+PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
+ folder from quota calculations, a direct delivery into this folder messed
+ up the contents of the maildirsize file. This was because the regex was
+ used only to exclude .Trash (or whatever) when the size of the mailbox
+ was calculated. There was no check that a delivery was happening into an
+ excluded directory. This bug has been fixed by ignoring all quota
+ processing for deliveries into excluded directories.
+
+PH/10 Added the maildirfolder_create_regex option to appendfile.
+
+
Exim version 4.61
-----------------
when small messages continue to be delivered. Without this change, the
"time since failure" will always be short, possible causing more frequent
delivery attempts for the huge message than are intended.
+ [Note: This change was subsequently modified - see PH/04 for 4.62.]
PH/20 Added $auth1, $auth2, $auth3 to contain authentication data (as well as
$1, $2, $3) because the numerical variables can be reset during some
PH/49 Installed latest patch from the Sieve maintainer.
+PH/50 When an Exim quota was set without a file count quota, and mailbox_size
+ was also set, the appendfile transport was unnecessarily scanning a
+ directory of message files (e.g. for maildir delivery) to find the count
+ of files (along with the size), even though it did not need this
+ information. It now does the scan only if it needs to find either the
+ size of the count of files.
+
+PH/51 Added ${time_eval: to convert Exim time strings into seconds.
+
+PH/52 Two bugs concerned with error handling when the smtp transport is
+ used in LMTP mode:
+
+ (i) Exim was not creating retry information for temporary errors given
+ for individual recipients after the DATA command when the smtp transport
+ was used in LMTP mode. This meant that they could be retried too
+ frequently, and not timed out correctly.
+
+ (ii) Exim was setting the flag that allows error details to be returned
+ for LMTP errors on RCPT commands, but not for LMTP errors for individual
+ recipients that were returned after the DATA command.
+
+PH/53 This is related to PH/52, but is more general: for any failing address,
+ when detailed error information was permitted to be returned to the
+ sender, but the error was temporary, then after the final timeout, only
+ "retry timeout exceeded" was returned. Now it returns the full error as
+ well as "retry timeout exceeded".
+
+PH/54 Added control=allow_auth_unadvertised, as it seems there are clients that
+ do this, and (what is worse) MTAs that accept it.
+
+PH/55 Added the add_header modified to ACLs. The use of "message" with "warn"
+ will now be deprecated.
+
+PH/56 New os.c-cygwin from the Cygwin maintainer.
+
+JJ/06 exipick: added --unsorted option to allow unsorted output in all output
+ formats (previously only available in exim formats via -bpr, -bpru,
+ and -bpra. Now also available in native and exiqgrep formats)
+
+JJ/07 exipick: added --freeze and --thaw options to allow faster interaction
+ with very large, slow to parse queues
+
+JJ/08 exipick: added ! as generic prefix to negate any criteria format
+
+JJ/09 exipick: miscellaneous performance enhancements (~24% improvements)
+
+PH/57 Tidies in SMTP dialogue display in debug output: (i) It was not showing
+ responses to authentication challenges, though it was showing the
+ challenges; (ii) I've removed the CR characters from the debug output for
+ SMTP output lines.
+
+PH/58 Allow for the insertion of a newline as well as a space when a string
+ is turned into more than one encoded-word during RFC 2047 encoding. The
+ Sieve code now uses this.
+
+PH/59 Added the following errors that can be detected in retry rules: mail_4xx,
+ data_4xx, lost_connection, tls_required.
+
+PH/60 When a VRFY deferred or FAILED, the log message rather than the user
+ message was being sent as an SMTP response.
+
+PH/61 Add -l and -k options to exicyclog.
+
+PH/62 When verifying, if an address was redirected to one new address, so that
+ verification continued, and the new address failed or deferred after
+ having set something in $address_data, the value of $address_data was not
+ passed back to the ACL. This was different to the case when no
+ redirection occurred. The value is now passed back in both cases.
+
+PH/63 Changed the macro HAVE_LOGIN_CAP (see PH/41 for this release above) to
+ HAVE_SETCLASSRESOURCES because there are different APIs in use that all
+ use login_cap.h, so on its own it isn't the distinguishing feature. The
+ new name refers directly to the setclassresources() function.
+
+PH/65 Added configuration files for NetBSD3.
+
+PH/66 Updated OS/Makefile-HP-UX for gcc 4.1.0 with HP-UX 11.
+
+PH/67 Fixed minor infelicity in the sorting of addresses to ensure that IPv6
+ is preferred over IPv4.
+
+PH/68 The bounce_return_message and bounce_return_body options were not being
+ honoured for bounces generated during the reception of non-SMTP messages.
+ In particular, this applied to messages rejected by the ACL. This bug has
+ been fixed. However, if bounce_return_message is true and bounce_return_
+ body is false, the headers that are returned for a non-SMTP message
+ include only those that have been read before the error was detected.
+ (In the case of an ACL rejection, they have all been read.)
+
+PH/69 The HTML version of the specification is now built in a directory called
+ spec_html instead of spec.html, because the latter looks like a path with
+ a MIME-type, and this confuses some software.
+
+PH/70 Catch two compiler warnings in sieve.c.
+
+PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
+ function verify_get_ident() calls ip_connect() to connect a socket, but
+ if the "connect()" function timed out, ip_connect() used to close the
+ socket. However, verify_get_ident() also closes the socket later, and in
+ between Exim writes to the log, which may get opened at this point. When
+ the socket was closed in ip_connect(), the log could get the same file
+ descriptor number as the socket. This naturally causes chaos. The fix is
+ not to close the socket in ip_connect(); the socket should be closed by
+ the function that creates it. There was only one place in the code where
+ this was missing, in the iplookup router, which I don't think anybody now
+ uses, but I've fixed it anyway.
+
+PH/72 Make dns_again_means_nonexist apply to lookups using gethostbyname() as
+ well as to direct DNS lookups. Otherwise the handling of names in host
+ lists is inconsistent and therefore confusing.
+
