Backscatter will get you blacklisted these days - there's enough junk mail on the net that backscatter doesn't help. Crank up your SMTP rejections if you can - greylisting works quite well for the hit-and-run spammer who doesn't use a real SMTP server to send the spam. Add in things like 'don't say HELO with my IP or name, or with a reserved IP' and you're doing well. Finally, look at using something like amavisd-new and quarantine mode - spam with a score > n gets quarantined instead of passed through. There are commercial products that will do this, along with Maia MailGuard and a few others, including a plugin for squirrelmail.
