Hmm... strange.  What version of Emacs is that?

It looks like smtpmail doesn't recognize the authentication methods
supported by your SMTP server: it should have issued the "AUTH LOGIN"
command before "ONEX", but didn't.  I wonder why...

Btw, are you sure your mail server indeed supports connections from
outside its domain?  It's possible that it doesn't, in which case
"Relaying denied" is expected: it tells you that it doesn't want to be
used as a mail relay (malicious hackers abuse that to send spam).
