Don't use the Control Access. What you did means "Don't accept CONNECTIONS from anyone except the barracuda". What you want to do us use "Relay for Addresses" and put the IP of the barracuda in there. That setting means "Relay for anyone who authenticates AND this list of IP addresses".

Anyone else have any ideas?

Put the IP of your Barracuda in the allow list. Users who authenticate can always send, regardless of any other SMTP security you have in place.

How do I go about setting this up in Imail? Do I need to Deny Access to everyone except my barracuda in the Control Access area in SMTP security? Does that still allow my users to authenticate and send messages? Thanks all for any help. I am just trying to stop all the DOS Attacks we have been getting.
