My domain's MX record is set to a forwarder at GoDaddy that sends mail to my Gmail account. I then use Fetchmail and Gmail's POP3 service to pull my mail down to my local Cyrus server. Thanks to setting up SPF records for my custom DNS with dyndns, I don't lose any outbound or inbound mail. All of my mail is going to a "legitimate" server and not coming directly from the dynamic range of an ISP.

Not off topic.  These are linux servers we're talking about.
