  From the post, you'd have to be rebuilding it every 15 minutes: > A real mail server which did SMTP properly would retry at some point, typically 15 minutes to an hour later. If it did retry and enough time had elapsed, we would allow it through.

    Still better than locking the tables every time you receive a piece of mail.
