Actually, there is an experimental extension for dovecot sieve that

It works quite nice in the current state, and will probably be included
some day by the dovecot sieve implementation.

Nice to know.
You'd still be better off feeding messages to SA from the MTA, and let
sieve just move messages around based on added headers.
I agree and that's exactly my current solution, but I have some
questions regarding how I'm doing that. Without repeating myself, can
you please have a look at my configuration in the mail that originated
this thread and comment on my solution?
I don't use SA myself so I have no experience with integrating it with
postfix, but some slacking around on the spamasasin website led me to
http://wiki.apache.org/spamassassin/IntegratedSpamdInPostfix, whose
first lines clearly mention the flaws you're system will run into
(generate backscatter, for instance)
My previous attempts in setting up a mailsystem that uses all kinds of
bells and whistles, but also tries to do everything on the smallest
scale possible (such as running content filters under system user
accounts), always failed miserable. In the end I implemented an
ISP-style setup even though my setup is only used by three persons and a
cat. I suggest you try the spampd or the amavisd-new approach.

For me a very smooth way to integrate spamassassin into postfix is via
spamass-milter. An advantage of milter is that it can access the body of
a mail before the server sends the accept to the client. It possible to
deny messages based on score during the smtp session and the job of
creating a bounce is on the sending side :-)
I use spamass-milter on two postfix servers running on debian-squeeze.
Works really very nice
