Wouldn't the more generally applicable fix be to simply *not* mess with the
layout of messages going through the server? Changing encoding is one thing, and
I believe the MIME spec says stuff about this being accepted, but rewriting the
whole structure and changing inline parts to attachment parts and stuff like
that seems like a sure-fire way to screw up all sorts of different things, not
just PGP/MIME and S/MIME.

Be liberal in what you accept, but *be conservative in what you create*. Plus,
it is not in the interest of the user to mangle their messages. If the recipient
would like to see it formatted in a certain way, he needs a MUA to do that for
him, it is explicitly not the task of the MTA. The SMTP spec has some stuff to
say about this too.
