Sophos will launch its own "SXL" real time spam rule update system in October, using DNS (Domain Name System) to update spam rules based upon the customers e-mail traffic and provide a much larger corpus of spam rules than static spam rule updates, said Graham Cluley, senior technology consultant at Sophos. Small, delta-based spam rule updates are sent every five minutes rather than every hour as they were previously.
