Content-Length and MIME encodings

which was, perhaps, sufficiently succinct to guarantee that it would be
misunderstood.  A couple of people have `disagreed' with that statement
as it stands, but both seem to have exactly the same position on this
issue as me.  So let me expand...

My understanding (which may be wrong) is that some systems use
Content-Length to separate messages in a mail drop.  Such a system (and
*only* such a system) must recalculate the Content-Length of incoming
messages when it writes them into a mail drop; just as a system which
uses the traditional `Unix' style of mail drop must ensure that there
are no lines in the message which begin with the characters "From ".

On any other system, using some other mail drop format, I would expect
Content-Length to be ignored, and woe betide any MUA that tries to use
it...
