All Barracuda Spam Firewalls, all firmware revisions.
To set up an SMTP welcome message, simply log into your Barracuda Spam Firewall and go to the Advanced > Email Protocol page. Scroll down to the bottom, under the SMTP Configuration heading; there, you can change your welcome message by entering the desired message into the SMTP Welcome Banner text field. The text entered will follow the 220 SMTP code when other machines connect to the Barracuda Spam Firewall on port 25.
