Well it doesn't really look at spam and discard it. It checks the IP
of the smtp connection and if it matches it against a list of known
bad IP's then it talks SMTP at a rate of 1 character a second and
responds with a 450 error every time. If the IP doesn't match, the
connection is forwarded on to the real SMTP server, Postfix.

There's no content scanning or decisions made, any IP that matches
the list gets the slow connection and 450 response.
