I agree that the dynamic dns services are pretty easy to set up and 
would probably work well for the stated purpose.

I did set up a dyndns account and enabled postfix on my notebook. I was 
happily sending mail using this setup, skipping using the .mac smtp 
server, until I started getting bounced messages from aol and at least 
one other service provider. They have their mail servers set up to 
refuse mail from a dynamically assigned host-name. I imagine that I 
could go to dyndns and pay for a higher level of service that will 
appropriately register my e-mail server with the internet, but that 
seems like overkill for what I want to do. So I recently went back to 
using smtp.mac.com for mail delivery, just in time for their service 
outage yesterday :-(
