Re: Bayes filter marking everything as ham

[Peter Carlson]

not everyone is an email expert that understands how RBLs work and that it's bad to share a recursive DNS server on an SA server. I will investigate this (URIBL_BLOCKED) further tomorrow (https://wiki.apache.org/spamassassin/CachingNameserver), however I doubt that it is causing the bayesian classifier to report as ham. https://wiki.apache.org/spamassassin/ImproveAccuracy I have gone through this wiki (and ones like it) at least a dozen times.   My server is blocking about 50% of the spam, thanks to some of the other layers of spam protection.  It's just bayes that I can't seem to get right Why is it marking all messages as ham? Probably because you're overtraining as ham. I have tried the following 3 scenarios: 1.  Training SPAM only  (it's in its own folder) 2.  Training a folder with known HAM 3.  Training with inbox as HAM In each scenario I carefully ensured that only SPAM was in SPAM and no SPAM was with HAM.  In all 3 scenarios it always marks every message as BAYES_00=-1.9.  Before each scenario I ran sa-learn --clear and sa-learn --sync add_header all Bayes bayes=_BAYES_,N=_BAYESTC_(_BAYESTCLEARNED_-_BAYESTCHAMMY_+_BAYESTCSPAMMY_),ham=(_HAMMYTOKENS(5,short)_), spam=(_SPAMMYTOKENS(5,short)_) I will try this as well to see what happens. Thanks for the responses, i do appreciate the help. Peter
