Change log file for Exim from version 4.21
-------------------------------------------
+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.
+
Exim version 4.61
-----------------
is given when verify = headers_syntax fails (if there are lots of them,
the message gets confusing).
+PH/35 Change the default for dns_check_names_pattern to allow slashes within
+ names, as there are now some PTR records that contain slashes. This check
+ is only to protect against broken name servers that fall over on strange
+ characters, so the fact that it applies to all lookups doesn't matter.
+
+PH/36 Now that the new test suite is complete, we can remove some of the
+ special code in Exim that was needed for the old test suite. For example,
+ sorting DNS records because real resolvers return them in an arbitrary
+ order. The new test suite's fake resolver always returns records in the
+ same order.
+
+PH/37 When running in the test harness, use -odi for submitted messages (e.g.
+ bounces) except when queue_only is set, to avoid logging races between
+ the different processes.
+
+PH/38 Panic-die if .include specifies a non-absolute path.
+
+PH/39 A tweak to the "H" retry rule from its user.
+
+JJ/03 exipick: Removed parentheses from 'next' and 'last' calls that specified
+ a label. They prevented compilation on older perls.
+
+JJ/04 exipick: Refactored code to prevent implicit split to @_ which caused
+ a warning to be raised on newish perls.
+
+JJ/05 exipick: Fixed bug where -bpc always showed a count of all messages
+ on queue. Changes to match documented behaviour of showing count of
+ messages matching specified criteria.
+
+PH/40 Changed the default ident timeout from 30s to 5s.
+
+PH/41 Added support for the use of login_cap features, on those BSD systems
+ that have them, for controlling the resources used by pipe deliveries.
+
+PH/42 The content-scanning code uses fopen() to create files in which to put
+ message data. Previously it was not paying any attention to the mode of
+ the files. Exim runs with umask(0) because the rest of the code creates
+ files with open(), and sets the required mode explicitly. Thus, these
+ files were ending up world-writeable. This was not a big issue, because,
+ being within the spool directory, they were not world-accessible. I have
+ created a function called modefopen, which takes an additional mode
+ argument. It sets umask(777), creates the file, chmods it to the required
+ mode, then resets the umask. All the relevant calls to fopen() in the
+ content scanning code have been changed to use this function.
+
+PH/43 If retry_interval_max is set greater than 24 hours, it is quietly reset
+ to 24 hours. This avoids potential overflow problems when processing G
+ and H retry rules. I suspect nobody ever tinkers with this value.
+
+PH/44 Added STRIP_COMMAND=/usr/bin/strip to the FreeBSD Makefile.
+
+PH/45 When the plaintext authenticator is running as a client, the server's
+ challenges are checked to ensure they are valid base64 strings. By
+ default, the authentication attempt is cancelled if an invalid string is
+ received. Setting client_ignore_invalid_base64 true ignores these errors.
+ The decoded challenge strings are now placed in $auth1, $auth2, etc. as
+ they are received. Thus, the responses can be made to depend on the
+ challenges. If an invalid string is ignored, an empty string is placed in
+ the variable.
+
+PH/46 Messages that are created by the autoreply transport now contains a
+ References: header, in accordance with RFCs 2822 and 3834.
+
+PH/47 Added authenticated_sender_force to the smtp transport.
+
+PH/48 The ${prvs expansion was broken on systems where time_t was long long.
+
+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.
+
