I just received a xymon alert with the subject line:

Xymon [530795] xxx.yyy.de:smtp CRITICAL (RED)

but the message body shows:

"green Fri Nov 28 12:01:26 2014 smtp ok Service smtp on xxx.yyy.de is OK (up)

220 xxx.yyy Mail Gateway ready

Seconds: 0.00

See ..."

My rrd-status.log contains some "bug"-messages regarding this server:

there is only 1 entry for the smtp.rrd file, all others are for the conn-test.

Any hints? Hermann-Josef Beckers
