+(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.
+------------------------------------------------------------------------------
+
+(313) 21-Jan-05 ? Multiple queues
+
+Exim runs poorly if its queue gets too big. Various ways round this are all
+to some extent kludges. There has been a suggestion of using multiple
+directories instead of just "input". (Originally it was for a whole set of
+spool directories, but that introduces complications with the hint files.)
+On message arrival, somehow a selection of "input" must be made. Then queue
+runners must be startable for the different "queues". Don't forget that the
+"msglog" directory is also involved. Perhaps add a new level of indirection:
+/var/spool/exim/queue1/{input,msglog}, /var/spool/exim/queue2/....

+
+(314) 15-Feb-05 M Multiple headers_{add,remove} for routers
+
+If headers_{add,remove} could be specified multiple times, it would be easier
+for those people that construct configs using .ifdef or .include, etc.
+------------------------------------------------------------------------------
+
+(315) 15-Feb-05 M String variables for use in filters.
+
+Currently, only numerical variables are supported.
