I am interested in seting up my linux server to be an email server. It is already a webserver hosting 14 domains and working great. But since it is hosting more than one domain, how do I set it up so the email addresses don't match the user logins? so I could have email@example.com & firstname.lastname@example.org and imap in to that box, not the users actual account.
I have imap installed, but I don't have sendmail installed.
