Postfix Antispam

This guide is for you if you control a mail gateway and either:

1. Are sick of spam getting to your Inbox or your user's Inboxes

2. Are sick of paying top dollar for a 'black-box' solution that only works for a couple of months

3. Want to know more about how Postfix can be used with other software to combat Spam

Note that this is a guide and should be treated as such. Read the guide, understand it and use the bits that meets your needs.
