You can integrate sendmail with spamassassin using milter
(e.g. http://www.mimedefang.org ).

AFAIK standard recomendation is to:

1) make milter reject messages with spam-index above 10 (more than 
standard 5.0) in reply to "the final dot" in SMTP session [spam "for 
sure"].  Such message will be rejected before cyrus has any chance to 
see them.

It makes the sending host responsible for generating bounces.

2) making milter add headers to remaning message and use sieve script to 
deliver "most likely spam" to separate folder e.g. INBOX/SPAM-FOLDER

e.g. use for fetchmail retrieved message:

if header :contains "X-Spam-Flag" "YES" {
   fileinto "INBOX/SPAM-FOLDER" ;
   stop ;
}

P.S. Use spamassassin with "bulk detectors" (dcc/razor)
