it may be better to change that to

to avoid punishing the form
Mime-Version: (Nosuch Mail 2.0) 1.0
which is valid, though I don't think I've ever seen it (comments are
usually on the right).
John, so many of my spams are hitting BOGUS_MIME_VERSION that I would
imagine it's worth sandboxing and incorporating into the primary
ruleset.
I've added both versions as unscored rules so we can see how they perform.
This would seem to be a pretty good poison pill, and although I imagine
you may not want poison pills within the primary ruleset,
They are generally not a great idea.
