Symptom: Message and content filters may recognize the body of a message as an attachment instead of as the message body if the MIME structure of a message is deeply nested, such as in the following example: multipart/mixed -> multipart/related -> multpart/alternative This has been found to cause the 'only-body-contains' condition to not match as expected. This will also cause the 'edit-body-text' action to not operate on the message body. Conditions: When messages containing a nested 'multipart/mixed' the filter condition 'only-body-contains' and the filter action 'edit-body-text' filter will not recognize the message body. Additionally, the filter condition 'attachment-contains' will detect content in the message body as being within an attachment when the email uses this MIME structure.
