This is one of five mail files that I received on the LSTSRV-L list in response to my question. I thought they are worth sharing. /duane weaver ----------------------------Original message---------------------------- > What do other list owners/ LISTSERV postmasters do in handling rejection > mail? I generally write a note to the postmaster at the rejecting site and ask for confirmation (if the message said "no such user"). If traffic on the list is heavy, I may not wait very long for confirmation, but I generally get an answer saying, "Oh, yes, that user is gone." I ignore messages that complain about obviously transient phenomena. Once, recently, I deleted a user immediately upon the very first rejection because it was a rejection of the message welcoming that user to the list! John
