I have changed it to + "/bin:/usr/bin". + +PH/04 SUPPORT_TRANSLATE_IP_ADDRESS and MOVE_FROZEN_MESSAGES did not cause + anything to be listed in the output from -bV. + +PH/05 When a filter generated an autoreply, the entire To: header line was + quoted in the delivery log line, like this: + + => >A.N.Other ... + + This has been changed so that it extracts the operative address. There + may be more than one such address. If so, they are comma-separated, like + this: + + => >ano@some.domain,ona@other.domain ... + +PH/06 When a client host used a correct literal IP address in a HELO or EHLO + command, (for example, EHLO [1.2.3.4]) and the client's IP address was + not being looked up in the rDNS to get a host name, Exim was showing the + IP address twice in Received: lines, even though the IP addresses were + identical. For example: + + Received: from [1.2.3.4] (helo=[1.2.3.4]) + + However, if the real host name was known, it was omitting the HELO data + if it matched the actual IP address. This has been tidied up so that it + doesn't show the same IP address twice. + +PH/07 When both +timestamp and +memory debugging was on, the value given by + $tod_xxx expansions could be wrong, because the tod_stamp() function was + called by the debug printing, thereby overwriting the timestamp buffer. + Debugging no longer uses the tod_stamp() function when +timestamp is set. + +PH/08 When the original message was included in an autoreply transport, it + always said "this is a copy of the message, including all the headers", + even if body_only or headers_only was set. It now gives an appropriate + message. + +PH/09 Applied a patch from the Sieve maintainer which: + + o fixes some comments + o adds the (disabled) notify extension core + o adds some debug output for the result of if/elsif tests + o points to the current vacation draft in the documentation + and documents the missing references header update + + and most important: + + o fixes a bug in processing the envelope test (when testing + multiple envelope elements, the last element determinted the + result) + +PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to + Electronic Mail") by including: + + Auto-submitted: auto-generated + + in the messages that it generates (bounce messages and others, such as + warnings). In the case of bounce messages for non-SMTP mesages, there was + also a typo: it was using "Auto_submitted" (underscore instead of + hyphen). Since every message generated by Exim is necessarily in response + to another message, thes have all been changed to: + + Auto-Submitted: auto-replied + + in accordance with these statements in the RFC: + + The auto-replied keyword: + + - SHOULD be used on messages sent in direct response to another + message by an automatic process, + + - MUST NOT be used on manually-generated messages, + + - MAY be used on Delivery Status Notifications (DSNs) and Message + Disposition Notifications (MDNs), + + - MUST NOT be used on messages generated by automatic or periodic + processes, except for messages which are automatic responses to + other messages. + +PH/11 Added "${if def:sender_address {(envelope-from <$sender_address>)\n\t}}" + to the default Received: header definition. + +PH/12 Added log selector acl_warn_skipped (default on). + +PH/13 After a successful wildlsearch lookup, discard the values of numeric + variables because (a) they are in the wrong storage pool and (b) even if + they were copied, it wouldn't work properly because of the caching. + +PH/14 Add check_rfc2047_length to disable enforcement of RFC 2047 length + checking when decoding. Apparently there are clients that generate + overlong encoded strings. Why am I not surprised? + +PH/15 If the first argument of "${if match_address" was not empty, but did not + contain an "@" character, Exim crashed. Now it writes a panic log message + and treats the condition as false. + +PH/16 In autoreply, treat an empty string for "once" the same as unset. + + +Exim version 4.54 +----------------- + +PH/01 The ${base62: operator adjusted itself to base 36 when BASE_62 was + set to 36 (for Darwin and Cygwin), but the ${base62d: operator did not. + It now does. + +PH/02 Two minor problems detected in Cygwin: the os.{c,h} files had lost */ on + the CVS lines, and there was a missing #if HAVE_IPV6 in host.c. + +PH/03 Typo: missing ".o" in src/pcre/Makefile. + +PH/04 Tighten up "personal" tests: Instead of testing for any "List-" + header line, restrict the check to what is listed in RFCs 2369 and 2929. + Also, for "Auto-Submitted", treat anything other than "no" as + non-personal, in accordance with RFC 3834. (Previously it treated + anything starting "auto-" as non-personal.) + +TF/01 The control=submission/name=... option had a problem with syntax + errors if the name included a slash character. The /name= option + now slurps the rest of the string, so it can include any characters + but it must come last in the list of options (after /sender_retain + or /domain=). + +PH/05 Some modifications to the interface to the fake nameserver for the new + testing suite. + +PH/06 Add ${if def:sender_address {(envelope-from <$sender_address>)\n\t}} + into the default Received: header string. + + + Exim version 4.53 ----------------- @@ -154,6 +320,76 @@ PH/36 When a locally submitted message by a trusted user did not contain a PH/37 Added control=suppress_local_fixups. +PH/38 When log_selector = +received_sender was set, and the addition of the + sender made the log line's construction buffer exactly full, or one byte + less than full, an overflow happened when the terminating "\n" was + subsequently added. + +PH/39 Added a new log selector, "unknown_in_list", which provokes a log entry + when the result of a list match is failure because a DNS lookup failed. + +PH/40 RM_COMMAND is now used in the building process. + +PH/41 Added a "distclean" target to the top-level Makefile; it deletes all + the "build-* directories that it finds. + +PH/42 (But a TF fix): In a domain list, Exim incorrectly matched @[] if the IP + address in a domain literal was a prefix of an interface address. + +PH/43 (Again a TF fix): In the dnslookup router, do not apply widen_domains + when verifying a sender address, unless rewrite_headers is false. + +PH/44 Wrote a long comment about why errors_to addresses are verified as + recipients, not senders. + +TF/01 Add missing LIBS=-lm to OS/Makefile-OpenBSD which was overlooked when + the ratelimit ACL was added. + +PH/45 Added $smtp_command for the full command (cf $smtp_command_argument). + +PH/46 Added extra information about PostgreSQL errors to the error string. + +PH/47 Added an interface to a fake DNS resolver for use by the new test suite, + avoiding the need to install special zones in a real server. This is + backwards compatible; if it can't find the fake resolver, it drops back. + Thus, both old and new test suites can be run. + +TF/02 Added util/ratelimit.pl + +TF/03 Minor fix to the ratelimit code to improve its behaviour in case the + clock is set back in time. + +TF/04 Fix the ratelimit support in exim_fixdb. Patch provided by Brian + Candler . + +TF/05 The fix for PH/43 was not completely correct; widen_domains is always + OK for addresses that are the result of redirections. + +PH/48 A number of further additions for the benefit of the new test suite, + including a fake gethostbyname() that interfaces to the fake DNS resolver + (see PH/47 above). + +TF/06 The fix for widen_domains has also been applied to qualify_single and + search_parents which are the other dnslookup options that can cause + header rewrites. + +PH/49 Michael Haardt's randomized retrying, but as a separate retry parameter + type ("H"). + +PH/50 Make never_users, trusted_users, admin_groups, trusted_groups expandable. + +TF/07 Exim produced the error message "an SRV record indicated no SMTP + service" if it encountered an MX record with an empty target hostname. + The message is now "an MX or SRV record indicated no SMTP service". + +TF/08 Change PH/13 introduced the possibility that verify=helo may defer, + if the DNS of the sending site is misconfigured. This is quite a + common situation. This change restores the behaviour of treating a + helo verification defer as a failure. + +PH/51 If self=fail was set on a router, the bounce message did not include the + actual error message. + Exim version 4.52 -----------------
