I am going to run my own email server for personal use. I am debating on which OS and server software I should run.
This naturally seems to be a linux sort of thing. I have historically had very, very bad experiences with linux. I have, however, found a server called iRedMail which is basically a wrapper for postfix, clamav, spam assassin, dovecot, and roundcube webmail. It doesn't install a firewall, but I'm looking at using shorewall. It installs pretty easily.
I am quite familiar with Windows, however, and have used a server called mailtraq.
My issue is that I am told linux will be more secure, but I know Windows a lot better. I find that I can get iRedMail running on a linux box, but I am pretty hard pressed to actually change anything. I don't know how I will ever administer this thing without understanding it and the documentation for postfix is, as is the usual with anything linux-related, arcane, poor, and intentionally cryptic.
I intend to keep my server behind my NAT if possible, so I can block any traffic not coming over a port used by email.
What do you all think? Whichever OS you recommend, list an edition / distribution and tell me why you think it's best.

Have you looked at MDaemon Free? It's for windows. I've never used the free version, but their pro version is very good.
