I've been watching this for awhile, and there is now a pattern to what I'm seeing.
I'm running a configuration with multiple users sharing a bayes files. This is an interim move to facilitate the spamassassin upgrades, and like many interim moves its been going on for a long time. When I first build the bayes files from my personal folders and my spam archives, things were great. 99.8% of the spam caught or better. Then, usually after a week or so, the number starts to drop. Right now, its down to 97%, in another day or two it will be down below 95%. With the amount of spam we receive, that is a lot of missed junk mail. So I blow away my bayes* files, rebuild, and I'm back up to darn near 100% caught. For about a week. Then the deterioration begins again. Has anyone else encountered this? Is this an artifact of too many users sharing a spam file? Also.... I retrain each night, feeding any missed spams plus any new hams received back through sa-learn. I can't see how that makes it worse, but who knows. Thanks - Jack
