Is it possible to parse attachments as attachments, even if it's marked as "Content-Disposition: inline"?

[feeedback]

Content-Disposition: inline
Content-Transfer-Encoding: 8bit
Content-Type: message/rfc822

....

Now if the attachment type is "Content-Disposition: inline", then the attachment is inserted into the main mail in "html", and the attachment headers are lost, which is inconvenient
