This + is correct for most verifications, but it is not correct for a recipient + verification with use_sender or use_postmaster set, because in that case + the callout does not use MAIL FROM:<>. Exim now distinguishes the special + case of MAIL FROM:<> rejection from other early rejections (e.g. + rejection of HELO). When verifying a recipient using a non-null MAIL + address, the cache is ignored if it shows MAIL FROM:<> rejection. + Whatever the result of the callout, the value of the domain cache is + left unchanged (for any other kind of callout, getting as far as trying + RCPT means that the domain itself is ok). + +PH/02 Tidied a number of unused variable and signed/unsigned warnings that + gcc 4.1.1 threw up. + +PH/03 On Solaris, an unexpectedly close socket (dropped connection) can + manifest itself as EPIPE rather than ECONNECT. When tidying away a + session, the daemon ignores ECONNECT errors and logs others; it now + ignores EPIPE as well. + +PH/04 Applied Nico Erfurth's refactoring patch to tidy up mime.c + (quoted-printable decoding). + +PH/05 Applied Nico Erfurth's refactoring patch to tidy up spool_mbox.c, and + later the small subsequent patch to fix an introduced bug. + +PH/06 Installed the latest Cygwin Makefile from the Cygwin maintainer. + +PH/07 There was no check for overflow in expansions such as ${if >{1}{4096M}}. + +PH/08 An error is now given if message_size_limit is specified negative. + +PH/09 Applied and tidied up Jakob Hirsch's patch for allowing ACL variables + to be given (somewhat) arbitrary names. + +JJ/01 exipick 20060919.0, allow for arbitrary acl_ variables introduced + in 4.64-PH/09. + +JJ/02 exipick 20060919.0, --show-vars args can now be regular expressions, + miscellaneous code fixes + +PH/10 Added the log_reject_target ACL modifier to specify where to log + rejections. + +PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_ + hostname. This is wrong, because it relates to the incoming message (and + probably the interface on which it is arriving) and not to the outgoing + callout (which could be using a different interface). This has been + changed to use the value of the helo_data option from the smtp transport + instead - this is what is used when a message is actually being sent. If + there is no remote transport (possible with a router that sets up host + addresses), $smtp_active_hostname is used. + +PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various + tweaks were necessary in order to get it to work: + (a) The code assumed that strncpy() returns a negative number on buffer + overflow, which isn't the case. Replaced with Exim's string_format() + function. + (b) There were several signed/unsigned issues. I just did the minimum + hacking in of casts. There is scope for a larger refactoring. + (c) The code used strcasecmp() which is not a standard C function. + Replaced with Exim's strcmpic() function. + (d) The code set only $1; it now sets $auth1 as well. + (e) A simple test gave the error "authentication client didn't specify + service in request". It would seem that Dovecot has changed its + interface. Fortunately there's a specification; I followed it and + changed what the client sends and it appears to be working now. + +PH/13 Added $message_headers_raw to provide the headers without RFC 2047 + decoding. + + +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 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. + +PH/13 If write_rejectlog was set false when logging was sent to syslog with + syslog_duplication set false, log lines that would normally be written + both the the main log and to the reject log were not written to syslog at + all. + +PH/14 In the default configuration, change the use of "message" in ACL warn + statements to "add_header". + +PH/15 Diagnose a filter syntax error for "seen", "unseen", or "noerror" if not + not followed by a command (e.g. "seen endif"). + +PH/16 Recognize SMTP codes at the start of "message" in ACLs and after :fail: + and :defer: in a redirect router. Add forbid_smtp_code to suppress the + latter. + +PH/17 Added extra conditions to the default value of delay_warning_condition + so that it is now: + + ${if or { \ + { !eq{$h_list-id:$h_list-post:$h_list-subscribe:}{} } \ + { match{$h_precedence:}{(?i)bulk|list|junk} } \ + { match{$h_auto-submitted:}{(?i)auto-generated|auto-replied} } \ + }{no}{yes}} + + The Auto-Submitted: and various List- headers are standardised, whereas I + don't think Precedence: ever was. + +PH/18 Refactored debugging code in route_finduser() to show more information, + in particular, the error code if getpwnam() issues one. + +PH/19 Added PQsetClientEncoding(conn, "SQL_ASCII") to the pgsql code module. + This is apparently needed in addition to the PH/07 change above to avoid + any possible encoding problems. + +PH/20 Perl can change the locale. Exim was resetting it after a ${perl call, + but not after initializing Perl. + +PH/21 Added a call to PQsetNoticeProcessor() to catch pgsql "notices" and + output them only if debugging. By default they are written stderr, + apparently, which is not desirable. + +PH/22 Added Alain Williams' LDAP patch to support setting REFERRALS=off on + queries. + +JJ/01 exipick: added --reverse (and -R synonym), --random, --size, --sort and + --not options + +JJ/02 exipick: rewrote --help documentation to hopefully make more clear. + +PH/23 Made -oMaa and -oMt work with -bh and -bs to pretend the connection is + authenticated or an ident call has been made. Suppress the default + values for $authenticated_id and $authenticated_sender (but permit -oMai + and -oMas) when testing with -bh. + +PH/24 Re-jigged the order of the tests in the default configuration so that the + tests for valid domains and recipients precede the DNS black list and CSA + tests, on the grounds that those ones are more expensive. + +PH/25 Exim was not testing for a space following SMTP commands such as EHLO + that require one. Thus, EHLORHUBARB was interpreted as a valid command. + This bug exists in every version of Exim that I still have, right back to + 0.12. + +PH/26 (n)wildlsearch lookups are documented as being done case-insensitively. + However, an attempt to turn on case-sensitivity in a regex key by + including (?-i) didn't work because the subject string was already + lowercased, and the effects were non-intuitive. It turns out that a + one-line patch can be used to allow (?-i) to work as expected. + + Exim version 4.62 ----------------- @@ -33,6 +258,25 @@ PH/05 Batch deliveries by appendfile and pipe transports did not work when the 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 -----------------
