I posted something about this a while ago; hopefully all your questions will be answered at http://peach.ease.lsoft.com/scripts/wa.exe?A2=ind0102&L=lstown-l&P=R2964 . >On a related note, can anyone explain why my list owners can receive >thousands of delivery errors, even with "Auto-delete=Yes,Full-Auto" >set for their list? This seems contradictory to the description of >the auto-delete setting. Basically LISTSERV can't automatically process bounces that aren't in a format it understands, so it has to forward such bounces to the listowner. Full-Auto vs. Semi-Auto doesn't change that; it just changes how LISTSERV handles bounces (in a format it understands) for addresses that aren't subscribed to the mailing list in question.
