Later today I'll be implementing a "drifting" spam/ham dividing line (one "line" for the entire system - not individually set per email account) to see how effective it is or how effective it appears to be.
I'm curious to know if the dividing line will drift into a wall on some self-imposed boundary edge or if it will converge to a point for us or if it will slowly drift around in circles.
I'm "determining" the dividing line by taking the average of all of the SA hits of all of the messages and changing the dividing line, on the fly, for each subsequent message.
Anyone want to tell me or speculate on how this experiment will end or what it will tell me, whether I'm listening or not?
For us, SA *seems* to score SPAM messages with lower and lower hit scores as time goes by, and the users get more and more glassy-eyed over it's ("my" if you prefer) effectiveness as time goes by too.
I've spent a lot of time with the bayesian stuff and sa-learn, but still it seems to drift downward.
And, I have to agree that SA is very good but requires a lot of attention by someone who knows what they are doing - which, of course, may or may not be me.
Nonetheless, I have this problem before me and am attempting a possible solution.
