Nothing good to say. The service has not only been useless but counterproductive since the day we installed it. Review collected by and hosted on G2.com.

1) It blocks an incredible amount of easily identifiable legitimate emails including clients, from family members and - this is the best - emails from the company that installed it on our servers. 2) It has ignored every whitelist request we've given it & 3) customer support is non-existent. I honestly don't understand how anyone with business accountability can allow this software to exist in their organization (we are removing it). Review collected by and hosted on G2.com.
