And what property of external bodies do you believe would prohibit implementing external bodies so that incoming material is buffered and scanned for viruses (and whatever else one wants to scan things for) the same way any local body part/ attachment scanned? Or extending the external body mechanism to support signatures -- either in the form of verifying that a signature or hash in the message matches one taken over the external body or an option and check on a signature attached to the external body. Seems to me that, at worst, all either would take would be defining of a new access type (see Section 5.2.3 of RFC 2046) that would make some material in the phantom body mandatory to pay attention to if present. Not exactly the sort of radical, earthshaking, change that justifies a claim that the mail system needs to be replaced. john
