[Xymon] Replacing the smtp test in protocols.cfg

[Richard Hamilton]

Ok, I checked the code (I think), and it does NOT appear to do variable
substitutions on the send strings.

But unless an SMTP server is set up to be very strict, one can probably get
away with sending "HELO bogus"
i.e. there has to be something after HELO, but the server may not care what
that is.  It's redundant with the envelope info in MAIL From: anyway, I
think.
