Configuring Cloudmark engine updates

Cloudmark distributes signature updates directly to the Antigen server. This differs from the other scan engines, which receive updates directly from Microsoft. Cloudmark signature updates are not configurable in the Antigen Administrator.

Administrator’s can schedule Antigen to check for a new version of the Cloudmark engine. Unlike the micro signature updates which occur throughout the day and are not configurable, administrators can schedule Antigen to check to see if Cloudmark has released an entire new engine. Because these “cartridge” releases occur much less frequently than the micro signature updates, it is recommended that you schedule this update to occur once daily during off hours. Historically, a new cartridge release occurs once every several months but these releases occur as needed.

For additional details about the Cloudmark engine, see Chapter 17 – Antigen Spam Manager overview in the Microsoft Antigen for Exchange User Guide.
