I'm looking to set up my own mail server at my house. Just 4-5 users. Pretty light usage. I want a package that is easy to set up and administer. I am familiar with Linux. I can work my way around the filesystem, etc. but am by no means an expert. Here are the specs that I am looking for:
1. Free (as in beer)
2. IMAP support
3. WebMail so that I can check my e-mail from any computer with internet access.
4. Ability to work with Spam-Assassin and some AV software if possible (this is a desireable, not a necessity)
I can put any version of linux on the box that's relatively easy to set up (i.e. most distros except for Slackware and Gentoo)
Thank you in advance for any assistance.
