A milter such as mimedefang could allow you to do filtering on a per-user basis on the mta level, if you are willing to write a lot of (perl in case of mimedefang) code. Actually, this is implemented in the commercial solution based on mimedefang, canit-pro (roaringpenguin.com) : each user can have his own "flow" and trigger filtering, including spf or greylisting if the administrator allows it.
Nothing to do with cyrus, or even sieve, though ;-)

We let people create Exim filters at the MTA level, but they operate on
delivery not as messages are accepted. They don't have access to all the
functionality that a system filter does, but Exim filters have more
functionality than Sieve filters.

We don't like that much, either. However, I'd be happy to allow users to
reject specific senders (a) at SMTP time, or (b) in the event that a
positive SPF or DKIM match were found. I don't know of any Sieve
implementations that meet those conditions, though.
