Switch off Postfix filters

[Alfredo Saldanha]

Dear,

I'd like to know if is there some way to disable automatic or manually 
Postfix filters in case of failure (overload) or something.
I'm asking this because I was an incident where, under an overload of 
messages, I had problems with my mx performance (very high CPU load and 
memory usage) to deliver messages through filters header and body checks 
and also a check for a policy server.
Somewhere in an overload, some messages were blocked, and would 
certainly "whitelisted" the Policy Server, but it was no longer 
responding to connections due to high load on the server processes.
Then ask them, is possible turn off or divert messages from filters like 
cidr (check_client_access), body (body_checks) and header checks in the 
event of an overload of messages?

Thank you,

Alfredo
