Check that you have the correct email address, that your have defined the SMTP server correctly, that there is no firewall in the way preventing you from contacting the SMTP server. Also check the mail serve rlogs to see if the request was rejected for configuration reasons - some mail servers reject incoming SMTP from non-trusted hosts, or they verify the FROM address is deliverable (so check what you sent as the sender address) and so on.
Of course, if you did not think you have configured thresholding or threshold emails then you should check your config as well!

On one of the boxes I get this error whenever a threshold email needs to be send out. ERROR: could not send thresholdmail to [email protected] at /usr/local/mrtg-2/bin/mrtg line 1831 I am running Redhat EL3 with MRTG 2.15.0 On the other boxes I am running Redhat EL4 or CentOS 4.2, no problems there at all. MRTG configurarion on the boxes is the same. Any suggestions are very welcome. _______________________________________________ mrtg mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/mrtg
