Here's my `typescript' of a telnet SMTP session to newsguy.  As you
can see, it worked perfectly.  Soon after recording this session, I
went back and sent myself some email via another telnet session to
`smtp.newsguy.com', and it worked fine.

Did you connect to `smtp.newsguy.com' or perhaps some other `newsguy'
host?
