Re: Can we configure MTA in bridge mode on Checkpoint TE appliance?

You can but setup needs to be proper on the network layer:

You must configure two dedicated network interface with IP to be used by the MTA.

So emails will be routed completely through these two interfaces.

A network packet that is seen by one of those two interfaces must NEVER be seen on the bridge.

Otherwise it will implicitly be dropped because the same packet was seen twice (on MTA interface and on bridge) which is a security violation and leads to a packet drop.
