Okay...I've calmed down now. Upon thinking more clearly, what we need (or more accurately, what I think *I* need) is to make it so that all mail from MAILER* (using the From: field in the headers) should be transferred to Postmaster. If someone gets mail from MAILER*, then it's usually a rejection notice of some sort. This, in fact, would fix all my problems. And besides, it's a little easier than checking the Subject line. --Marc P.S. Afterthought, this wouldn't help nodes who use BITMAIL@xxxx or other nodes that don't use MAILER@xxxx as their mailer. But we can ponder this.
