Both are best used to reject mails before they even have to be delivered (in Postfix, this is a sender or recipient restriction, see the websites of the two projects for more details on how to set them up), so as a added bonus, people don't have to scroll through endless lists of mails marked as "***SPAM***". I've had a setup with amavisd-new, spamassassin and clamav on another mail server (basically the same thing Chuck described), but for our current usage, these two are efficient enough not to warrant the upgrade to more powerful hardware (which would be required to run SpamAssassin properly). -- Heiko Wundram Product & Application Development
