(I'm not the original poster.) I've read some documents (on the order of a year ago) and still have not set up my mail server. I believe (and I'm looking for confirmation) that I don't have to have a registered domain name to run a mail server. To get specific, I have an email address at my isp ([EMAIL PROTECTED]). When I set up my mail server at home, I plan to give it an arbitrary fully qualified domain name (that will not be registered) and then use aliases or whatever to make the system work. (I'll probably use fetchmail to get the mail, let postfix / procmail sort it, then let postfix send it. I won't need the FQDN for fetchmail, but I guess I will need if for Postfix so that upstream mail providers don't think I'm an illegal relay (or whatever).) (I'll probably use something like system8.home.z as my non-registered FQDN, where system8 is the host name of my main Linux box, home is the workgroup of my Windows network, and z is totally arbitrary, but avoids any chance of collision with a real two or three letter top level domain.) Detailed pointers would be appreciated, but a general "yes, this can work, you're on the right track" (or the opposite) would be very helpful.
