EXIM 4 WISH LIST
----------------
The problem with header_remove followed by header_add is that you can't refer
to the previous value of the header when adding a replacement. This could be

A separate but related issue is the effect of headers added by "unseen"
directors. These are documented in chapter 19 as not being accumulated. Should

(155) 16-Jun-2000 M Special handling for certain hosts
feature would use a regex to match whole lines and replace them. It could be
useful for patching up syntactically invalid lines from crappy clients, before
the syntax check kicks in. (It might also be useful for hiding local host names

(58) 26-Jun-02 ? Extend PAM support

from the message at arrival, before data_acl processing (and before the
-rcpt_acl warn headers are added to the message)."

(63) 28-Jun-02 S Access to ACL-added headers in ACLs
"I'd like also to be able to look at the already added headers by a
rcpt_acl when still checking rcpt_acl (either later in the acl for the same
-RCPT TO or for another RCPT TO)."

(162) 28-May-03 M/L Use of real numbers in filters, expansions, and options

(315) 15-Feb-05 M String variables for use in filters.

-(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
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.
+However, it doesn't seem possible to detect a dropped connection without trying
+to read from it.
------------------------------------------------------------------------------
(328) 10-May-05 S After "unseen" routing, pass on header additions/deletions
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.
+pass them on to both addresses. See also 333.
------------------------------------------------------------------------------
(329) 12-May-05 S Create message ID at MAIL FROM time
messages in the log would be tagged with an ID, and this is seen as desirable
by some people.

+(330) 31-May-05 ? Default interface for -bh and default port for -oMi
+
+I do not think it worth putting effort in here for these reasons: If a host has
+multiple interfaces, there's no easy way to choose one to be the default for
+$interface_address when -bh is used. If the host does not have multiple
+interfaces, chances are the configuration won't be looking at
+$interface_address anyway. If you are setting -oMi, and care about the port, it
+isn't much effort to tack on a port number, though in this case, I suppose a
+default of 25 is "obvious".
+------------------------------------------------------------------------------
+
+(331) 31-May-05 M More than one retry time per host
+
+Consider this example: an attempt to start a TLS connection to a host gets a
+temporary error. This stops *all* connections, both for TLS and otherwise.
+Different retry times for different circumstances are needed to get round this.
+What are the circumstances? TLS/not-TLS is clearly one, but sometimes you don't
+know if you are going to try TLS until you have connected. So this makes sense
+only if require_tls is used. Perhaps the multiple retry times should just be
+per-transport, to avoid these difficulties. If we made all retry keys depend on
+the transport, this would happen automatically.
+------------------------------------------------------------------------------
+
+(332) 03-Jun-05 S A "receive time taken" log selector
+
+This suggestion is to at an RT= item to the <= line, giving the time it
+actually took to receive the message.
+------------------------------------------------------------------------------
+
+(333) 06-Jun-05 L Re-think and re-implement header handling
+
+There are a number of items related to headers above. Better facilities for
+handling headers at ACL time are needed. The whole way in which Exim handles
+headers should be re-planned and re-implemented in a more consistent manner.
+
+These are the main previous items:
+
+Exim 3 Wish List: 41, 85, 149, 187.
+Exim 4 Wish List: 55, 62, 63, 160, 212, 237, 270, 314, 328.
+------------------------------------------------------------------------------
+
+(334) 07-Jun-05 M Support for messages larger than 2G
+
+This is probably a longish-term thing at the moment. Quotas over 2G are now
+supported, but not individual messages; no doubt one day this will be wanted.
+------------------------------------------------------------------------------
+
+(335) 14-Jun-05 T Re-arrange default configuration
+
+A small niggle which might be worth fixing is the ordering of the ACL in the
+default configuration file. The relay_from_hosts and authenticated clauses
+would be better off before the dnslists examples. However, this should be left
+until a x.x0 release, because of the documentation implications.
