I have the Nagios alert monitoring system installed and has been running fine for a while now but recently i had some corrupt conf files (I thought only my httpd.conf) and made some network config and httpd.cong changes before i actually found the correct problem. So now things are back up and running but nagios alerts (and im pretty sure any other mail) is failing to be sent out. Here is file from my /var/spool/clientmqueue folder:
Is there anyway i can find out whats causing this? logs, etc? Where is the "transcript?
