Just wanted to let everyone know that our lookup tool now includes the BRBL from Barracuda. For email administrators who wish to use the BRBL directly (e.g. from within Microsoft Exchange, IBM Lotus Domino, sendmail, Postfix, and qmail, etc.) please note that you need to register your email server IP addresses directly with Barracuda Networks.

For users of our Email Blacklist Lookup Tool, we’ve taken care of the registration process for you. You just need to enter your Email server’s IP address in our tool to see if it is in the BRBL database.

Please let us know if you have any related problems or questions.
