	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.
