The problem using things like dyndns and forwarding to a dynamic ip is 
that there is a possibility that when your ip has changed mail would be 
attempted to be delivered to the next user that gets your previous ip.

Even with v. low dns timeouts there is still that risk.

Better to get a static ip, or failing that use a pull system 
like fetchmail.
