I am looking to implement Spamassasin. I have probably overlooked something but cant find a way that I can have it sit between the Internet and my mail server. I am using Exchange 2000 and converting from it to something else wont happen for a while. Is there a way to have it function as a smtp proxy for lack of a better word ?
Well, SA in itself doesn't do any mail handling at all, so you'd need some kind of tool to handle it.
If you know of some kind of transparent proxy software that can call mail filters, you can probably use that.
However, most people (myself included) that need this kind of functionality end up using a non-transparent method. Just create a forwarding mailserver that runs SA, and have it scan and forward the email over to your exchange server. Then set up your internet MX records to point to the forwarding server.
