I have now tidied the source and removed it altogether. +PH/33 When a queue run was abandoned because the load average was too high, a + log line was always written; now it is written only if the queue_run log + selector is set. In addition, the log line for abandonment now contains + information about the queue run such as the pid. This is always present + in "start" and "stop" lines but was omitted from the "abandon" line. + +PH/34 Omit spaces between a header name and the colon in the error message that + 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. + Exim version 4.60 -----------------
