Sorry for the delayed reply - this got buried in my inbox. To combat this, Mailman removes the following headers from posts delivered to list members: return-receipt-to disposition-notification-to x-confirm-reading-to x-pmrqc If you have seen another header that causes some MUA or MTA to return a receipt, please let me know what it is so we can remove that too. > If yes: Is there a way to intercept and delete these requests on the > Mailman host? As I said, we try. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
