I don't think we are on the same page. You do not need to do any configuration of SMTPL because it gets its information on which lists it is supposed to receive mail for by checking to see which lists exist on the server. Therefore you do not need to create any mailboxes in SMTPL. That was what I meant when I said "this is handled internally by SMTPL". SMTPL is not the problem here. It is clearly running and it answers when I connect to it. The fact that a machine on your local subnet can't open port 25 on the LISTSERV machine on that same subnet suggests a local firewall rule problem to me. Nathan
