No, because there is no reason to assume anything about mail with a
crypto signature unless you have a priori knowledge about the signing
agent.

This is the same misunderstanding that has lead some people to imagine
that mail that passes SPF or DKIM or whatever should automatically be
whitelisted.

For S/MIME and PGP it's also because the amount of signed mail is too
small to matter in most mailstreams.
