Let me try and follow you.
You have a mailserver at home that you are using that is configured using your legal domain name that you bought.
Your ISP is doing DNS for your domain name.
You have your server configured to send and recieve mail through a legal IP address (probably from DSL).
You can send and recieve mail in between your workstations at home just fine.
You can send mail to the outside world just fine (ie someone@aol.com).
But that someone@aol.com cannot send mail to You@home.com.

If I followed right then I would say it sounds like your ISP needs to add a MX (mail) DNS record for your mail server. (ie MX record legal internet IP mapping of yourmailserver.yourdomainname.com)

One way you might want to check this is see if you can go to a friends or work (somewhere whith internet connedction) and see if you can ping your mail server by name (ie ping yourmailserver.yourdomainname.whatever) as long as you are not denying pings with your firewall.

By the way are you running DNS at home for your workstations? If so is it the same server that is doing your mail?
