Yeah, that doesn't sound good.  What I think would be workable is to
create a feature that emails you an archived message, and requires that
you're logged in with your community account.  That sounds hard enough
to abuse by spammers and convenient enough for actual users.

I wonder if it would break stuff like DKIM signatures, SPF checks, and
the like.
