Tech site Z-oc.com has written up a simple yet powerful tutorial on how to use Gmail to manage all of your email accounts in one fell swoop.

It's more than a matter of simply assigning forwarding rules willy-nilly, obviously - you get to set up a whole email management system. By the time you are finished with this, all your email can be actually managed from within Gmail with the domains kept separate but controlled inside of your Gmail workspace.
