 Right, but to run a "real mail server" you need a static address.  Which

Sure they can. For sending e-mail, all you need is an IP address. It would help if the reverse DNS is set up correctly, and that you claim this same name in the SMTP dialog, but this isn't required.

For receiving mail, all you need is a domain name, which has a set of advertised MXes. Those MXes could point to mail servers operated by friends of yours who might use UUCP, or some private routing method to send your mail to whatever your current IP address is. Those MXes could even point to your own host/domain names, and the mail would be deferred until such time as you re-connect with your dynamic DNS provider and update the IP addresses for these names.

Works just fine.
