That confirms that my understanding of "relaying" is correct.  But then I don't see how
the port 587 helps. The earlier comment was:

"SMTP-with-authentication-by-default; no relaying. The well-known port is
587. See RFC2476."

If there is no relaying, then I could not use that port to send e-mail to our customers.
Or am I mis-understanding the "no relaying" part...or taking it out of context?
