And one more point ...

It turns out that when you do a "telnet [hostname] 25", this looks to
the receiving host no different than a connection via any other means.
Therefore, no matter what the newsguy staff might have said, there is
essentially no way for a remote SMTP server to disable telnet access
via port 25 and still allow other forms of SMTP access, at least
when the basic protocol is being used.

Just a point of information that I meant to add to my previous message
about this.

And once again, HTH.
