All Barracuda Spam & Virus Firewalls, all firmware versions.
Barracuda Networks has partnered with emailreg.org to improve the deliverability of legitimate email over traditional IP "whitelist" services. To help combat spam email, domain owners register their domains and sending IP addresses with emailreg.org. Registering domain information and sending IP addresses in pairs compels domain owners to take responsibility for email that both emanates from their registered IP addresses and uses their associated domain information. Pursuant to registry with emailreg.org, domain owners are required to provide their contact information and agree to respond to reports of spam that reflect their IP and domain information.
The Barracuda Spam & Virus Firewall exempts emailreg.org registered IP address and domain name pairs from specific spam filtering layers to avoid potential false positives and to reduce overall system load. Spoofed domains or email originating from registered IP addresses that do not come from the registered domains are scanned normally.
To audit emailreg.org listings, Barracuda Central monitors submissions of spam samples from customers. As part of its relationship with emailreg.org, Barracuda Networks has priority escalation privileges to resolve problems with emailreg.org listings. Emailreg.org in turn works to resolve these issues with its registered contacts.
Barracuda Spam & Virus Firewall customers should report any problems resulting from emailreg.org domain / IP address pairs to Barracuda Networks by submitting spam samples to Barracuda Central. For more information about how to submit spam samples, please refer to Solution #00002387.
