Leaving your A and MX records to guys at DynDNS has some more concerns (like security... for paranoid people) and lots more...

Isn't the fact that your IP address could suddenly change a security problem as well? You could quite easily have attempts to deliver mail to the wrong place. There is no guaranty that everyone's DNS servers will honor very short TTL.

If security isn't a concern, your WRT54G already has software that will update your records at dyndns.org immediately after the IP changes. I did not see anyone mention that.

This might be off topic, but why do so many people insist on running mail servers at home? Most cable modem and DSL IP ranges are on a lot of mail servers blacklists, for one thing. Reliability isn't terribly high, either. You can get a small and reliable virtual server for $10 a month (or less), and the box you are on will likely have connectivity through more than one large ISP (my provider seems to have 6 very high speed connections.
