McAfee DLP Prevent and Postfix MTA

Jump to solution
Hello evetyone, I am trying to configure Postfix to redirect emails to McAfee DLP Prevent. But the postfix cannot check for a missing header. Is there a ready-made instruction for configuring a postfix? Or is it better to use another MTA?

I solved this problem with using multi instance in postfix (http://www.postfix.org/MULTI_INSTANCE_README.html).

I set DLP Prevent as relayhost for first instance and create header check for X-RCIS-Action.

If message header has "Allow" value, message sent to the second instance, which has empty relayhost.
