EXIM 4 WISH LIST
----------------
22-Apr-04: Implemented for domains, addresses, and local parts. Hosts are
too messy!
+
+The only sensible approach seems to be to allow IP address arguments only.
+Anything else should be diagnosed as an error. However, if a name appears in
+the list, a PTR lookup should be done. This may require a lot of refactoring
+in the code.
------------------------------------------------------------------------------
(74) 22-Jul-02 M Extend -bV to do more semantic checking
------------------------------------------------------------------------------
(202) 10-Oct-03 S -bvsomething to do a callout after the verify
+
+For example: -bvc and -bvsc. The problem now (Nov 04) is that there are quite a
+few possible callout options that can be specified in an ACL, and they would
+have to be replicated here.
------------------------------------------------------------------------------
(203) 14-Oct-03 S verify=something to easily check for header presence
(215) 14-Nov-03 S A way of turning off message-submission fix-ups
Globally, and perhaps also via an ACL control so that it can be done on a
-per-message basis.
+per-message basis. Is this still needed? Since this item was added to this
+list, default fixups for non-local messages have been removed, and control =
+submission has been added.
------------------------------------------------------------------------------
(215) 26-Nov-03 M/L Conversion of IDNA domain names for logging
------------------------------------------------------------------------------
(223) 22-Dec-03 S Support SOA lookup in dnsdb lookups
+
+This could be like zns, and climb up the tree till it hits a zone. Would the
+name of the zone be required?
------------------------------------------------------------------------------
(225) 22-Dec-03 M Add acl= to routers
Given that pids are reused non-cyclically these days, is this actually useful?
------------------------------------------------------------------------------
-(269) 26-May-04 U Run both a system and a user filter in test mode
-
- exim -bF systemfilter -bf userfilter -f sender@dom < message
-
-This would allow testing the way the userfilter handles the system
-variables set by the systemfilter.
-------------------------------------------------------------------------------
-
(270) 01-Jun-04 M Add headers at top and middle
Various initiatives like SPF and DomainKeys require header lines to be added
(280) 23-Jun-04 M A way of adding a header line after callout defer_ok
This would record that, e.g., a sender domain verified, but the callout
-could not be done.
+could not be done. There are ways of fudging this, using ACL variables and
+"warn" statements.
------------------------------------------------------------------------------
(285) 16-Jul-04 M Separate and independent log_selector for rejectlog
This could be added to "verify=header_syntax" or, if the incompatibility is
felt to be too great, an additional condition, or a sub-option, could be added.
------------------------------------------------------------------------------
---- HWM 307 ------------------------------------------------------------------
+
+(308) 24-Nov-04 S Add $body_longlinecount and $header_longlinecount
+
+These variables would hold the number of physical lines in the body and header
+that were longer than 998 bytes. This would be fiddly to implement because of
+the way Exim currently reads the input. It isn't just a trivial patch.
+------------------------------------------------------------------------------
+
+(309) 01-Dec-04 S/M Queue runners should get locks before forking
+
+If a queue-runner opened the -D file and took out the lock before forking, it
+would waste fewer resources if the message was already being delivered. But how
+often would this actually matter in practice?
+------------------------------------------------------------------------------
+
+(310) 06-Dec-04 S After "personal" save what matched
+
+The idea is to save the email address that actually was found in the message
+in a variable so it can be used (e.g. as the From: address in an autoreply).
+------------------------------------------------------------------------------
+
+(311) 07-Dec-04 ? More flexible SMTP response codes
+
+The requestor wanted to be able to specify, for example, 551 in an ACL deny
+instead of 550, and also vary the defer code. The first digit, however, should
+remain fixed. In addition to main codes, enhanced status codes (RFC 2034) were
+requested. (As far as I can tell, they have never been highly popular.)
+------------------------------------------------------------------------------
+
+(312) 10-Dec-04 ? Shadow remote transports
+
+Unless a lot of work is done, this would be restricted to another remote
+transport. A similar effect could therefore be achieved with "shadow_hosts"
+which are like fallback_hosts but which operate on success.
