IP Block Lists
Is there anyway of leveraging online tools / sites like Barricuda and SpamCop and block known offenders right at the firewall? We have Microsoft Forefront for doing this but that means the junk from known senders gets right through the front door and into the mail server. I think it would be great if there was a way to check each connection right at the firewall against Barricuda, SpamHaus, SpamCop, etc. and block them right there.
Is there anyway of doing this with pfSense?
You may want to look at the SpamD package, works like a charm for me.
