I am having issues where legitimate bounces, out of office messages, delivery receipts, and so forth are being marked as spam due to no watermark or sender address.
Treat Invalid Watermarks with No Sender As Spam = high-scoring spam
It appears that these messages indeed to not have a valid watermark or sender address anywhere, even though they are legitimate incoming emails.
Is this expected behavior?  It appears that many remote servers strip off the original MIME Header...
