It's my understanding that very few of these come back to the list address any more (they used to do it regularly: I remember lists being flooded with dueling auto-receipt messages). > Is there a way I can prevent return receipts being sent to the list? If they're going only to the individual sender, it's an annoyance, but no big problem. Receipts being distributed on the list are, and I contact the sysadmin or postmaster from the offending address (since normally you _can't_ contact the user). I've assumed it was impossible to catch them generically before distributing them on the list, simply because if it were possible it'd have been done. -- Russ __|~_ Russell A.
