RE: SMTP exit program?

["York, Albert" <albert.york@xxxxxxxxxxxxxx>]

Tom,

If you are familiar with sockets programming you could write your own SMTP
server/relay program.

        Well, I need to do _some_ relaying because our NT-based Domino
server is
        hiccuping way too much (especially since I installed the latest
security
        patches), and we rely on it for email for several sites.  So... I
relay all
        SMTP that comes in to our Domino server out to the SMTP on the 400.
It
        works, but my ability to monitor the email is gone for the most
part.

        If I could just write an RPG program to verify the from/to
addresses, that
        would go along way towards keeping us off of the various
block-lists.
