Optimizing DSPAM + MySQL 4.1
Falko Timme writes "DSPAM is a scalable and open-source content-based spam filter designed for multi-user enterprise systems. It is great at filtering out spam but on busy mailservers the pruning of the MySQL databases takes way too much time. The default purge-4.1.sql script provided with DSPAM can be heavily optimized by adding indexes to the database and using the indexes properly when pruning."
