Hey! No hijacking threads! Email me Dan.
Clon: the other question is, is he running a dedicated server? If so, he should look at Zimbra or something.
If he's on a normal, everyday virtual server, well, there's a good chance he has access to Webmail already. I'm assuming he has a site, as opposed to just a domain name? If he has CPanel or Plesk to manage his server, then he probably already has access to it.
