EmailReg.org also hosts statistics and data on email being sent using your domain. You can find out which IP addresses are sending email claiming to come from your domain. This is truly useful information for controlling who is actively using or abusing your domain name.
EmailReg.org is a Web site where people can register their domain names and email server IP addresses to indicate domain ownership and to provide contact information for responsible parties to notify if spam is detected.
Barracuda Spam & Virus Firewall administrators can configure their systems to use EmailReg.org to apply policy to inbound email. Emails from domain names and IP addresses that are properly registered on EmailReg.org can be automatically exempted from spam filtering defense layers on the Barracuda Spam & Virus Firewalls throughout the world. As long as email administrators do not implement policy to specifically block your email, your email will not be accidentally blocked as spam if your domains and IP’s are properly registered at EmailReg.org.
