I also can see from the maillog that when the smtp check occurs
Sep 29 11:05:01 oscar postfix/smtpd[27269]: connect from unknown[x.x.x.x]
Sep 29 11:05:01 oscar postfix/smtpd[27269]: improper command pipelining after MAIL from unknown [x.x.x.x]Sep 29 11:05:01 oscar postfix/smtpd[27269]: disconnect from unknow [x.x.x.x]
so obviously the smtp check is sending something postfix doesnt like/handle.? That isnt a bhiggy in itself - bgut it nojw makes me wonder out of curiosity exactly what the logic of? the smtp check is..
I also tried Jeremy's example of "ehlo xymonnet\r\nquit\r\n" in protocols.cfg - that also has the same warning/error in maillog
?improper command pipelining after EHLO from unknown[x.x.x.x]
all jolly wierd,....

what triggers the smtp check?
Ive had instances where the test goes red, and then just a few seconds later back to green.? So this isnt a standard "every 5 minutes" clearly ?
