Setting up a mail server on Ubuntu

Yesterday I bought a cheap computer as a phylogenetic workhorse. Today I installed PhyLiS, and have been working on getting a mail server configured so that I can get the thing to automatically send me results of analyses over the coming weeks. This blog post gave me the general gist of the commands required to send mail. After a few unsuccessful attempts at sending mail, I learned from this site that I needed to set myself up as a mail server. Thanks to the community documentation for Postfix, I was able to fairly painlessly it up and now have the ability to send messages from the linux command line.
