I finally finished moving my email server from a self hosted setup to Gmail for Domains. There were three main parts of the move: configuring inbound email to end up on the Gmail servers, copying all my current email to Gmail, and then setting up local mail to be sent using Google’s SMTP server. The most time consuming part of the move was copying all my current mail over using a nice utility someone had written. Configing the DNS services and watching the changes propigate was the most interesting part of the move.
Postfix has been replaced with ssmtp on my server, and I now have a few extra CPU cycles and MB’s of memory to dedicate to Apache, Lighty, and MySQL.
