User namespace is the main issue. If all the users of all mail domains handled by a server are listed in the system password file, then you just add all the domains to mydestination. This also implies that bob@example1 is the same person as bob@example2. Postfix handles this easily, but this is not a common situation. If each domain has its own user list, then there must be some way to list which users go with which domain. Postfix calls these virtual domains. This also allows for bob@example1 and bob@example2 to be different people. This is by far more common. > > I hope the reader can see the relationship between these questions. > Feel free to ask for clarification on any point. > You will probably benefit greatly by studying the basics of computer mail. Change your mail display name. Mail arriving labeled from "Me" when it obviously isn't might be considered abusive or a spoofing attempt. -- Noel Jones
