Hello Wei Feng,

 

Thanks for the inquiry. I wanted to follow up with you to see if you were aware of the Cyren, formerly CommTouch Spam reporting processes.  Please review the article for more details.  Since the Add-On is a third party application we do not have access to the details on what they record as Spam or the weights applied.  If you have legitimate emails being blocked please let us know.

 

 

Thank You.
