You need to set the Relay options to either Relay for Addresses, which will allow you to specify network blocks or computers that do not need to authenticate or No Mail Relay which will require all connections to authenticate.

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.
