What does a Unix mail server do with mail it receives that isn't to any users on it?
Is there a way to setup a list (one that contains a list of E-mail addresses and where to forward them) that the mail server checks then forwards E-mail it receives even though it isn't to any user on it?
aliases.
if your useing sendmail check
/etc/aliases
# Test mail address to these people to mimic an external trading partner
external:jim@convict.com,me@warden.com,james@jefro.com
now lets test.
echo This is a test email for the 3 people in my list|mailx -s "Testing Aliases" external
and all 3 people would get the mail.
