$10/month for ACS.

But there is another problem with hosting a mail server on a dynamic IP.
if you are using as service like dyndns to point a name at your mail
server, when your connection goes down, and then comes back up, you'll
probably have a different IP address. And someone else could have your
old IP address. So, until you update your dyndns profile, and the TTL on
your mail server name expires, somebody else could be getting mail
destined for your machine. Or, if you connection goes down for a while
(and you *can't* update your dyndns record), then somebody else could be
getting your e-mail for a LONG time instead of the remote mail server
not connecting and waiting to deliver when you come back up.
