You can add aliases to "/etc/aliases"
vim /etc/aliases
format should be:
user:
[email protected] (where 'user' is setup on the local server)
to copy forward:
user: user,
[email protected] (where 'user' is setup on the local server)
Once you've done this, run "newaliases" and restart postfix with "/etc/init.d/postfix restart" (depending on your distribution).
