So my Trendnet TV-IP110w IP-camera, which when sending e-mail begins the
SMTP session by sending "ehlo MAPI1.0", is not adhering to accepted or
universal SMTP conventions.  

And as pointless as it is, my 12-year-old Post.Office SMTP server
software is correctly terminating the session with a "501 Invalid domain
syntax" error.

That's what I wanted to know.
