I've been using linux servers for years, and always configured mail server without too much thinking, following online guides, etc. I know that postfix can have a virtual alias file, but after taking a look I found no guide using exclusively that.
I'm looking for a guide to configure a linux mail server (preferably with a debian-based linux) that would have pop, smtp AND imap that would have emails entirely configurable in a text file. (This is for the only purpose of simplicity)
Any suggestions?
Thanks!
