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.

Yes -- do a reverse lookup on your IP number and use that name in your
sendmail config. 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.

Matthew
