If you're using an ISP that issues you a dynamic DNA address then you 
don't have any visible domain and mail server to anyone outside. Without 
a permanent domain, IP address, and MX record other MTA's can't reach you.

You might want to look into www.dyndns.com, they provide the service you 
will need at a fraction of the cost of having Comcast convert you to a 
commercial account with a static IP address. I make no claims for 
dyndns, I just know it as a possible option, I have no experience with it.
