Our old system is Spam Assassin, new is Sophos A sample of tagging correctly over the last 8 days, Sophos 54% 61% 61% 75% 81% 61% 61% 62% 515% 64% - Average Spam A 77% 78% 75% 79% 78% 75% 74% 64% 600% 75% - Average I am sort of perplexed, Sophos is updated every hour automatically, Spam Assassin 2 or 3 times a week manually.... Ever since we put the new system in Spam Assassin seems to be consistantly beating it (Sophos)......yet Sophos is costing us an arm and a leg..... Is there anybody else who has experienced this sort of thing? Is there anything that could be skewing the statistics unfairly? regards Thing
