It is used by mailing lists servers to deliver digest of messages. This type of messages has a global content-type of type multipart/mixed, containing an initial text/plain part (including the summary and then) and then a multipart/digest part. The multipart/digest is made of multiple message/rfc822 MIME parts. Reproducible: Always Steps to Reproduce: 1.Read a multipart/digest message that has an important number of message/rfc822 parts (try with 50) 2. 3. Actual Results: The current behavior is to consider contained messages as attachments. If the number of contained messages is too high, firefox gives priority to the "attachments" window and the diest message is no more readable. Expected Results: The expected behavior for the mail client, when receiving a multipart/digest message would be to print the summary and contained messages inline.
