I am planning to use a single, remotely hosted server with on IP as a mail server (as well as a web server) for sevral virtual domains. The server currently has a name but it is of no significance (and is not identified as belonging) to any of the public domains.
As I understand things, I must have one mydestination domain, and it must not be listed in the virtual_alias_domains map. When setting up Postfix to serve multiple virtual domains and virtual mail boxes for, say, e1.com, e2.org, and e3.net, is there any reason to select any particular one for mydestination? Thanks, Best regards, -Tom
