How to set up a secure SMTP server using Ubuntu Server 10.10

http://www.itshouldwork.org/2011/04/howtosetupasmtpserver/

This will be a three part series covering how to set up a secure SMTP server that you can use on your network to send mail from fax machines, APC Environmental Monitor, etc. Part one will cover installing Ubuntu Server, part two will cover installing WebMin, and part three will cover installing and setting up PostFix. There are many ways to go about doing this. This is just the way I have chosen to do it. If you have suggestions or improvements to this series please let me know in the comments.

NOTE: I will be installing this on a VWWare box with 512MB of RAM, a 12GB HD, and 64-bit CPU. You can use an old workstation or server if you don’t have a virtual environment.
