We have a Cisco ASA Firewall and Exchange 2013. We're utilizing Barracuda's cloud-based SPAM filtering solution but SPAM is still coming in outside of the SPAM filter. Barracuda recommended limiting their IP ranges being the only IPs that can hit port 25 (64.235.144.0/20 and 209.222.80.0/21).

I know enough to configure but really would love some help on adding the Access Rules on the ASA.

Thanks!
