The Spam Quarantine Notification scheduled task reports as having failed and not all end users are notified of messages waiting in the Messaging Gateway spam quarantine, after approximately 20-30 minutes.

When the spam quarantine notification process takes too long to complete, usually due to rate limiting by the receiving server, the underlying database connection may time out resulting in a failure to complete the notification process.
This issue was resolved with Messaging Gateway 10.5.4. Spam quarantine notifications now complete without encountering a network timeout.
