We’re currently testing out the Cloudmark Authority system on our mail servers to see how it performs with our system. The fastest way to do this was by using their SpamAssassin plugin under the new rule “CMAE_1” in our SpamAssassin configuration.
If you have issues with scoring you can change the score for CMAE_1 (default is 10) in the SpamAssassin preferences. If you have issues with false positives or spam that wasn’t caught please send us a copy of the X-Spam-CMAE-Analysis header.
UPDATE: The CMAE_1 rule has been disabled. We never received pricing from Cloudmark to continue post-trial and we have other projects that need attention at the moment. We may revisit this in the future.
