Nagios alerts not being received

[mlk0506]

Hi,
I've been having an issue for awhile, where some Nagios email alerts are not being received. For most of my servers i am getting them, but for a select few i am not getting any. In the notification log, it says they are being sent. The odd thing is that All of my servers are configured the same way to send alerts, so i can't find any discrepancies there. What would you suggest? and what further info do you need from me?

on a side note, I checked with my email administrator and none are being blocked.

When you look at the Home -> Notifications page, are you seeing a log of the missing notifications being sent?

Please provide a list of working hosts / services, and non working hosts / services (so we have a comparison), then post or PM a copy of your /usr/local/nagios/var/objects.cache file for us to review. Also, let us know the contact that you are expecting to receive notifications as.
