I'm looking for some help for a novice in the emailing world.

what i'm trying to do is, emails send trough form go to:
[email protected]
when i reply i want to reply with [email protected]

now i would have about 5 of these setups.
and here comes my problem.
how do i easily view all 5. Is there some way to do put them in folders or something? (i'm using cpanel)
how are you guys doing this?
