Check 'MIME From' and SMTP 'MAIL FROM' against SPF

We've stumbled upon SPF recently: when a foreign domain has valid SPF for
himself, it can send emails to our domain with smtp 'mail from:
anyaddress at domain.com <mailto:anyaddress at domain.com> ', but state 'From:
user at ourdomain.com <mailto:user at ourdomain.com> ' in MIME header, and it
won't cause SPF checks in SpamAssassin to fail. Is there any way I can check
MIME from against SPF? Seems like I'm missing something here.
