ALEX@AUVM is the "real" sender. The reply-to is to let us know this (he could have just as easily left it off). Create your own BSMTP mail file and send it class=M to a non-paranoid mailer. Since LISTs are usually config'd to send minimal headers, the ones that non-paranoid mailers insert to point out possible impersonations don't make it to the list members. ---------- Mark J Strawcutter BitNet: MJSTRAW@IUP Director, Systems and Data Communications InterNet: [log in to unmask] Indiana University of Pennsylvania AT&T: (412) 357-4000 Indiana, PA 15705 "you can't nail jello to a tree"
