Smart Outbound Relay and Inbound delivery.

[Limo.Net]

I'm trying to interface a Barracuda 300 to a new Cpanel/Centos 4.4 x64 dual Opteron's server.

I'm having trouble with the following....

#1 trying to direct outbound mail thru a Smart Relay aka a Barracuda Spam Firewall for lightweight outbound scanning. I have tried a couple of tweeks I have found in the forum but I can't get outbound mail directed thru the smart relay.

#2 If I tweek the MX record of the domain to point to the Barracuda mail will be delivered to the Barracuda just fine. Problem is the Cpanel/WHM server will not accept the incoming SMTP connection from the Barracuda for local delivery. And all mail bounce
