I was thinking about doing exactly this -- my email is currently running on a
fairly low cost dedicated server, but I was considering trying to move the
actual email server in-house and using a VPN tunnel to a lower cost VPS with a
static IP.

Are there any gotchas with this approach? I would think only exposing SMTP on
the remote computer would be the best thing to do, and make everything else
only accessible via VPN.

Happy Friday!
