Subject: [Nagios-users] check_smtp problem


Hi all,

I know this is more suited to the plugins list but there really isnt much
activity there, so I thought I would post here (apologies to any if this is
out of order).

My problem is that with a fresh install of Nagios 1.04b using the 1.3b1
plugins, I am getting a CRITICAL response to some check_smtp service
checks.

Nagios is running on a RedHat 7.3 system (installed from source not RPMs),
the check_smtp is the default command and actually works succesfully on
most of my mail servers. In fact, on the problem servers the check returns
an "SMTP OK: 0 second response time", but still returns CRITICAL as the
service status. The details are as follows;

Domino 5.11 smtp server - OK: 0 second response time - CRITICAL
Domino 5.10 smtp server - OK: 0 second response time - CRITICAL
MS Exchange 2000 server - OK: 0 second response time - CRITICAL
qmail smtp server - OK: 0 second response time - OK
MAILsweeper esmtp server - OK: 0 second response time - OK

All configs for the above services and servers are identical (except IP
address of course!) It appears that the problem is only occuring on Domino
and Exchange servers.

Has anyone seen this problem before, and if so is there a solution? I would
like to go live with the monitoring system, but really would prefer to have
notifications working correctly on our mail servers. I have looked briefly
at the source code of the check_smtp but cant find anything that glares out
at me. (Havent coded in a looong time). I now throw myself on the combined
wisdom of the list.

Any takers?
