I didn't (and still don't) like the .BITNET-hack for reasons explained in the
past :-). On the other hand I understand the desire to support *local* nodes -
strictly meaning LOCAL.
There are two things I think are easily missed:
a) LISTSERV provides more than mail service. If you convince LISTSERV that
PIGSFEET is a valid address (because MAILER forwards to SMTP) then what do
you expect will happen if CATSHEAD@PIGSFEET sends LISTSERV a "GET FANCY
MODULE" ?
b) Even more important is automatic command forwarding.
1) You have a peered list. Above CATSHEAD@PIGSFEET sends a REVIEW command.
The request is forwarded to the peers. Now *they* will have problems
sending to PIGSFEET.
2) The user sends a SUBSCRIBE FarAway-List. Since your LISTSERV doesn't
host the list but knows that it's at OTHRNODE the request will be
forwarded to [log in to unmask] What would you expect should be done
then?
Without modifications to LISTSERV you can't prevent local node users to "slip
out" into BITNET appearing as having a valid NJE address. LISTSERV was not
designed as gateway or double-headed server. Thus every site not on BITNET
must send to LISTSERV with domained addresses. And it would be a good idea
that these addresses (you can choose your local ones) a resolvable everywhere
in BITNET, i.e. they should be reachable via one of the upper level domains.
