Exchange 2010 RBL Check

[scrantic]

Hi Guys, anyone point me in the direction to fix ERROR: No response from BL server (alarm) on the Blacklist status check in Nagios XI? I set this up with the monitoring wizard and haven't fiddled with the settings at all.

This check actually runs against external webservers not your exchange server. Does the nagios server have access to the internet?

Thanks I appreciate that, I'm aware of how an RBL check works and the box does have access to the internet.

OK, lets go ahead and just verify that you can connect to the majority of the systems. This is assuming you are using the default black list providers in the check. If you have added more, please included them and let me know what modifications have been made.
