[ale] Looking for advise on domain names and other info wrt local network.

[Jim Popovitch]

Maybe I'm not seeing all of your question (stupid gmail bb app).. (Top
posted too!) But the generic mapping line in main.cf will convert
local users to external users. I.E jimpop at localhost or
jimpop at server.foo into jimpop at realdomain.tld

Hth,

-Jim P.
