I would say most definitely.... depending on the firewall, it might even block some of the DOS attacks itself. I use and like Cisco Pixes, but administer a lot of SonicWalls...good bang for the buck with them.

MAKE SURE the Barracuda machine will only forward mail destined for your domain(s) or you WILL end up an open relay as IMail will relay for anything coming from the Barracuda.
