Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I've just set up a new Debian web server which I have done plenty of times before, but I want to add a mail server which I have never done before.

I am aware of this question, but I would like someone to recommend packages and briefly explain how to use them for providing pop/imap access on multiple domains, a concept that has confused me for a while.

I'm planning for this server to grow slowly but surely, from serving an initial 5 or 6 domains to about 20 in the first year, continuing at this rate. (yes, I've jumped on the cloud bandwaggon).

At the moment, I have a DNS-A record pointing to my server's IP and nothing else. I'm assuming that I need a DNS-MX record pointing there too, but I haven't read up about it yet so today that's what I'll be doing. Hopefully reading up on the subject and the help that I get here will get my server up and running in no time.

Thanks!

It's a well-documented solution, which is extendable. Discussion about it on the mailing list and directly on the howto pages.

Great tutorial. It does go very deep for newbies, but if you stick at it, it gets everything covered! –  Greg Jan 12 '11 at 9:24
    
Right, my mailserver setup is based on that howto since Debian Woody. Just in case, look at my howtos (lugh.ch/howtos) some of them are based around this solution. –  weeheavy Jan 12 '11 at 9:27

I'd recommend virtual mailboxes on postfix with setup described here: http://www200.pair.com/mecham/spam/virtual2.html
