This is not directly a Declude questions, but yet still does apply. I am getting a "Top Rate Controlled by IP" report from my Barracuda box that is acting as a pre-filter to my Declude server. What I am noticing in the reports is that the top 20 IP addresses are in 8-10 /24 ip blocks. I have started a firewall rule in my upstream firewall and have started adding IP address ranges to drop packets. Each IP address so far typically tries to send between 5k-15k messages a day. Each IP block make up about 30k-80k message. My though is by blocking the worst offenders at the firewall I should be able to reduce the load on my SPAM equipment.
My question is... Is/Has anyone else tried this approach If so is there an impact on the amount of mail your server had to process? The second part of the question would have to deal with the overhead to process a message via RBL. Would the firewall approach to blocking IP addresses of known bulk spammers, or is Declude going to be just as efficient with testing via RBL.
