No, python isn't needed.  I'm running Postfix, Cyrus, and SA and I don't
use python at all with it.  I do, however, use amavisd-new, or more 
accurately, amavisd-new with maia mailguard patches which both
lets you use SA and gives you a very nice web interface to SA that
would work well for virtual users.  The key is to use mail reinjection
with postfix to feed it to amavisd-new which runs SA and other checkers
(like clamav) and then gives it back to postfix.  This is all done using
SMTP.  Mail is then passed to Cyrus using LMTP which passes it
through sieve.  

One nice thing, btw, that Maia Mailguard gives you is a _very_ _easy_
way to handle bayesian training.  The user can, through the web interface,
indicate what e-mails are spam and what's not and maia will take
care of feeding that back to SA for learning.  It also lets the user manage
individual white/black lists.

Cheers,
Tanner
