Bah! All that says is connection timeout. No indication of *why*. You're not even getting the SMTP banner there. I suspect it's probably something to do with an administrative descision on behalf of UMD admins -- perhaps they reject connections to hosts in DUL block lists. > I'll give a shot at changing my domain name - what should I use?

It may not look pretty, but it should let you see if that is the problem. The other thing to do is forward all of your e-mail via your ISP's smart host. As you are probably expected to do.
