For the past couple days we have been experiencing a very high volume of failures with Mimedefang and Spamassassin. Over 90% of the messages are either Read Receipts or Delivered Receipts. Mimedefang and sendmail are posting the "reject=451 4.7.1 Please try again later". Below is a full exerpt from the mail log on one of these failures.

We have disabled this filter but are still experiencing the errors. Any help or recommendations are greatly appreciated. Thanks.
