EXIM 4 WISH LIST
----------------
particular, it would allow failing of certain 4xx codes.
This is now available for 4xx responses to RCPT commands. Is anything more
-needed?
+needed? Apparently, yes; there's been a request for a similar feature for MAIL
+commands.
------------------------------------------------------------------------------
(148) 15-May-2000 S Warn recipient if message rejected for quota excession.
AUTH during the callout checking, on all types of connection. I suppose that
means making TLS available as well. This probably means a rewrite of the code
that actually does the callout. Should we use the relevant transport in a new
-"callout" mode instead of keeping things separate? See also 253.
+"callout" mode instead of keeping things separate? See also 253 and 323.
And here's another submitted idea: "My actual suggestion is that if this model
is followed, the parent process doesn't have to stop the callout process if it
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.
+------------------------------------------------------------------------------
+
+(316) 21-Feb-05 M Put callout response into a variable
+
+When a callout fails, put the entire SMTP response into a variable. This is not
+trivial because we probably should retain it in the cache as well.
+------------------------------------------------------------------------------
+
+(317) 25-Feb-05 S Delete the pid file when the daemon exits
+
+At least try to catch some of the exit routes from the daemon and either delete
+or empty the pid file.
+------------------------------------------------------------------------------
+
+(318) 02-Mar-05 S Add current connection count to daemon's exiwhat output
+------------------------------------------------------------------------------
+
+(319) 03-Mar-05 ? Allow file rather than directory for scanning call
+
+"I can call arbitrary scanning software by specifying the full path. I can pass
+a directory to be scanned in the arguments. I'd like to be able to pass a
+specific file name instead of a directory. I think this would allow me to call
+Bogofilter at smtp time. Bogofilter requires a filename, not a directory. The
+file would contain the complete email. I suppose there may be other scanning
+solutions with a similar requirement."
+------------------------------------------------------------------------------
+
+(320) 03-Mar-05 T Options to control daemon retry binding
+
+Currently the daemon tries 10 times at 30-second intervals to listen on an IP
+address. The wish is for options to control these numbers.
+------------------------------------------------------------------------------
+
+(321) 07-Mar-05 S Run an ACL on a sync error
+
+... and possibly "accept" or "deny" it.
+------------------------------------------------------------------------------
+
+(322) 15-Mar-05 M Add a /defer_ok option to verify=reverse_host_lookup
+------------------------------------------------------------------------------
+
+(323) 15-Mar-05 M Make callouts use smtp_data from the smtp transport
+
+This is yet another problem caused by duplicating the SMTP code between the
+transport and the callout verification. See item 294 above. Merging the
+transport and the callout code could prevent this kind of thing from happening.
+------------------------------------------------------------------------------
+
+(324) 04-Apr-05 ? Make -bP show ACLs
+
+This is in the Bugzilla as #10.
+------------------------------------------------------------------------------
+
+(325) 28-Apr-05 ? Support for quotas over 2G in appendfile.
+
+Things get bigger far more quickly than I ever imagine...
+------------------------------------------------------------------------------
+
+(326) 03-May-05 ? Queue-only on memory shortage
+
+This is bugzilla #17. The idea is to have something like queue_only_load that
+triggers on a shortage of main memory.
+------------------------------------------------------------------------------
+
+(327) 06-May-05 ? Break delay if connection drops
+
+Currently, "delay=5m" (e.g.) waits for 5 minutes. If we can detect that the
+connection has died in the meantime, it would make sense to break the delay.
+------------------------------------------------------------------------------
+
+(328) 10-May-05 S After "unseen" routing, pass on header additions/deletions
+
+Currently, when an "unseen" router accepts an address, header additions and
+deletions stick with that address, and the "clone" address that continues to be
+routed starts off without any additions or removals. This request is for an
+option to select other actions: retain header actions with the clone only, or
+pass them on to both addresses.
+------------------------------------------------------------------------------
+
+(329) 12-May-05 S Create message ID at MAIL FROM time
+
+Currently, the ID is created only when Exim is about to create the data (-D)
+file for an incoming message. In other words, after it knows it really is going
+to accept the message. Creating the ID earlier would mean that rejection
+messages in the log would be tagged with an ID, and this is seen as desirable
+by some people.
