Dear Listserv List -- In one of my several capacities at UC Berkeley I am the postmaster for UCBCMSA (viz. cmsa.berkeley.edu). One of our networking guys recently forwarded to me a complaint from the administrator of a system out there. It seems that this administrator had had a user who had subscribed to a UC Berkeley list, and this user had left and was no longer receiving mail, so the administrator wanted this user to be unsubscribed to the list. Apparently the administrator had sent mail to the owner of the list in question using the OWNER-LISTNAME@HOSTNAME convention. He claims that this mail was bounced back to him as undeliverable. I checked the list and saw that there is indeed several owners defined for this list. My question: Why did this guy's mail bounce? Under what circumstances does the OWNER-LISTNAME@HOSTNAME convention not work? Do we have to do something on our system beside define the list owner(s) in the header of the list??? Thanks in advance. By the way, this person (the administrator of the remote system) never sent me his bounced mail, so I don't know whether he's really correct or whether he mis-typed something. However, I'm being hounded by our networking staff to determine whether something is wrong on my system. So your help will be greatly appreciated. Thanks again. *=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=* David Kalins Postmaster for UCBCMSA Central Computing Services University of California, Berkeley "What we don't know Berkeley, CA 94720 far outweighs what we do."
