There will be an update to the configuration of the spam filtering systems to automatically perform sender validation on inbound emails on Tuesday, 11/7/20, at 11:00 am EST (8:00 am PST). This update will provide a more comprehensive spam filtering process by validating the sending servers on every email sent to eliminate the potential for sender address spoofing. 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. If you have any questions or issues regarding the update please contact support.
