Every so often we update the list of blacklists we curate.  This is part of our service to ensure that we provide the best information for our customers.

Today, MxToolbox is taking the CASA CBL lists offline.  As of July 2016, the China Anti-Spam Alliance has announced the deprecation of the following lists:

• CASA CBL+
• CASA CBL-

Since these lists will no longer be supported, they are no longer useful for making decisions regarding the delivery of email.

If you have questions about these changes, please contact our Support team.
