Comment 3 for bug 848183

When you send a mail message that bounces, the mailer daemon's bounce message is
generally a multipart mime message where your original message is enclosed as a
message/rfc822 attachment. It would be nice to have an easy way get at this
attachment so you can re-address, edit and resend it. Being able to drag an
attachment from the bounce message window to the Drafts folder would allow this.
