However, I suspect that most reassembly agents won't
bother to deal with imbedded message/partial objects. I know my code sure
doesn't; you'd have to explode and redeliver the parts to get the thing to
reassemble.
Actually, this is one of the few advantages to the generally-stupid way
that metamail implements message/partial -- it will work just as well
even if the parts are embedded in a multipart.
