Is it possible for listserv to SERVE out a mail server or domain. How can I SERVE it back if so?

E.g., a "batch program" that would send the same message to the list, would end up with "duplicate" errors. We had to modify (at some risk) the loop-check http://www.lsoft.com/manuals/1.8e/owner/owner.html#kLoopcheck While you're at it, do a SERVE appl_sender_address Just a tho't. /Pete
