Case Study: B2B2C boosts email filtering accuracy and performance with Cloudmark Authority

B2B2C - Customer Case Study

B2B2C, a Montreal-based Canadian internet service provider with more than 20,000 mailboxes, was relying on an open source messaging security platform built around Apache SpamAssassin. While its tuned rules and plug-ins achieved a 79% accuracy rate, the company was spending significant staff time maintaining rule sets, and the heavily loaded system had become slow and difficult to manage, with CPU utilization at critical levels.

Cloudmark provided Cloudmark Authority™ for SpamAssassin, a carrier-grade plug-in that integrated without re-architecting the environment. The solution lifted filtering accuracy from 79% to 98%, reduced false positives, cut CPU utilization by more than 50%, and improved message throughput by 400%, helping B2B2C stabilize operations and improve customer satisfaction.
