Hi Jeremy,

The message above is also what I'm seeing in the Xymon message, and you are 
right. There is of course no output from the EHLO response.

This change avoids the log message on the mailserver, but the xymon server 
only sends quit, and looks at the initial greeting banner. Which is still 
better than nothing. But doesn´t he with the other configurations? And 
probably I could leave the ehlo simply away.

The piplining log messages are thrown on the mailserver because the xymon 
server sends multiple commands on the same time. But if you are sending only 
ehlo the Mailserver will complain about inpropperly closed sessions.

Kind regards
	Lars
