Resolved after 1 day 1 hour, affecting Inbound Security, on September 9, 2025.

resolved Sep 10, 2025, 07:23 PM UTC

After thorough investigation we found: - A new log entry was added each time a piece of mail was deferred - “No Delivery Status Found” mail log rows didn’t get updated when the email was later delivered - Instead, a brand new mail log entry with the “Delivered” status was written
