I've decided to switch my slacker mail over to apps for google.  This may cause some headaches like having to add people to my new google + account but I won't have to worry about shutting down my web server and missing mail.  It seems to be quite easy to do, just a few dns settings and bang the power of google behind your email.  I'm already using blogger to post my website blog and perhaps one day I'll move the pictures over to google.
