I've been playing around with OSX Lion Server installed on my home fios connection on a mac mini server. Apple built a webmail interface that's not as good as gmail, but works if you primarily use a client and just need webmail sometimes. I'm not ready to switch to it full time, but have been curiously looking around for alternatives to gmail. In general, running an email server yourself is a bit of a pain.
