We have about 100 servers using CSF, and CSF is generating A LOT of mail alerts.. which is causing us to receive over 1000 mails daily, just from CSF alerts.. this doesn't include support emails or others.

My question..

How do you handle mail alerts when you have lot of servers? See... i can not waste 5 hours reading every mail.. even if I start deleting those mails a lot of important and critical alerts can be erased in the process..

How do you filter or handle this kind of things?
