Did anyone figure out how to get DSpam and Postfix to work as a mail filtering gateway? If so, can you please post the howto. I've been using piratefish for a while now, and although it works, the accuracy rate is only around 70%. I read up about DSpam and found that the accuracy rate is very high, around 99%. I would really like to put this filter into effect as my email gateway in front of a Microsoft Exchange Server. Also, I would like it to scan the mails for viruses before it relays them to the Exchange box. If anyone has come up with a HowTo for this setup, please share as it would be very useful and greatly appreciated.
