[Xymon] SMTP checks

[Ian Diddams]

 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,....

secondary question...

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 ?
