Hey guys, I'm trying to get my server back up to snuff. I'm using Debian Squeeze right now and I'm up and atom with apache, mysql, php, pureftpd, ssh, and I have squirrelmail installed.

My dilemma comes with the mail part of the whole ordeal, Postfix and Courier are installed, have their keys made, and for what I assume, are configured correctly. HOW do I make new virtual users? My domain points to this machine as well as my MX record for mail.mydomain.com.

I need IMAP and POP working. And upon the creation of new email users, will SquirrelMail interface with Postfix and Courier? When I installed SM I set it up for use with Courier.

Any suggestions?

Here is a link to the postfix virtual readme. It would be a good place to start with understanding how virtual domains and virtual transport works with postfix. In essence, you will need to create a set of map files or configure a database with the user and account information. I personally, like the postfixadmin PHP based too for this purpose, but you need to have an appropriate underlying structure fist.

What do you mean exactly when you say How functional, exactly, is your mail server minus the virtual portion?
