I did this: impressive.net now rejects any mail that spamassassin
scores higher than 10. Woohoo!

The mail is rejected during the initial delivery attempt, with
this error message:

    550-Sorry, this smells like spam; rejected. For more info, please see
    550 http://impressive.net/people/gerald/2004/01/spam.html

This should reject about 2/3rds of all mail to my site. I feel
better already :)

This was *really* easy to set up thanks to the exim4-daemon-heavy
package in debian sarge which includes a patch called exiscan-acl.
