|Either via a List Keyword (preferrable) or by using an exit routine?

With EXITS, all things are possible; but basically native mode does NOT
filter on arbitrary Subject:s.  There are some RESERVED subjects that
LISTSERV(R) won't distribute due to their being highly indicative of an
automated response back to the list.

Another special case is the TOPICS feature.  See my attachment.
|If not, is it being considered for the next version of Listserv?

It takes 3 things to accomplish your task via Revised LISTSERV
techology:

1) list-owner has setup the list's TOPICS feature in the
   definition (see example below)

2) you, the subscriber, have done a LISTSERV

   SET listname TOPICS: -FWD

   which only is effective for mail distributions, and not
   for DIGEST/INDEX mailings

3) the sender uses a valid Subject: in their posting

   SUBJECT: FWD: xxxxxxx

Here is an example syntax using HEPROC-L topics=

* Topics=          HEJ,Con1,Con2,Con3,Con4,Con5,Con6,Con7,Con8,Con9

Notice that there is nothing magical about FWD and is not a valid
explicit topic for this list (thus it would be treated as the
reserved OTHER: topic).
