Change log file for Exim from version 4.21
-------------------------------------------
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.
+
Exim version 4.60
