You both missed the entire point of my original question.

So I will repeat it. 

===========
Recently I've been trying to figure out why a Trendnet TV-IP110w
IP-camera was not able to connect to my SMTP server to send mail.

I performed some packet analysis and found that the camera was greeting
the server with this:

  ehlo MAPI1.0

And my server responds with this:

  501 Invalid domain syntax

In looking at the ehlo specifications, the greeting is supposed to
contain something that looks like a domain-name.  So I believe the
string "MAPI1.0" is being rejected by my server on that basis.
============

So you see, it's not that this camera wasn't generating a "ehlo"
greeting.

The issue is the "MAPI1.0" part of the ehlo greeting that my SMTP server
apparently doesn't like, and it doesn't seem to like it because
according to SMTP standards "MAPI1.0" is not a valid domain-name.

Comments?
