We run a fairly big Internet/NETNORTH gateway, and through-mail from BITNET/NETNORTH/EARN LISTSERV lists occasionally bounces back to the list. Recently, a list maintainer wrote to us asking us to change the Subject: line on our bounce messages so LISTSERV would recognize them as such and not reinject them. Assuming BSMTP/SMTP mail, how does LISTSERV recognized bounce messages, and if it uses the Subject: to tell, what Subject: lines does it look for? Thanks in advance. -- "Anyone forging articles should be writing news software instead, if you get the headers right you're ahead of some implementations.
