so I have a DynDNS domain, that I have pointed to my router, and I want to make a mail server for that, to test with, get it setup, then I can move my REAL domain to it... All I want is a simple setup, 2-3 users, just to test incoming ( and outgoing) emails to a dnydns domain. What is the simplest, easiest setup I can do? -- Paul Cartwright
