UPDATE:

The planned update has been completed.

ORIGINAL POST:

There will be an update to the software on the SpamTitan spam filtering systems on Monday, 12/20/21, at 2:00 am Eastern (11:00 pm 12/19/21 Pacific). This update will provide a more comprehensive spam filtering process, including geoblocking functionality, and enhanced functionality of associated components. The spam filtering system is fully redundant and each system will be updated individually.

There is no expected interruption of either inbound or outbound mail flow during this update.

Accounts using Reflexion, Office 365 Exchange Online Protection, or third-party spam filters will not be affected.

If you have any questions or issues regarding the update please contact support.
