There ISNT a 'quick' way :)

If you are using RH, just go into "linuxconf" and go to server / mail delivery system

there you need to set up

Virtual Email Domain
Virtual Domain User Aliases.

then READ the helpfiles in these two options. they are quite useful.

(this all assumes that DNS and so on is set upp correctly.)
