That is how I have been doing it and no problems so far. Spam tagging is 
better than ever. This is the first time I've used Bayes and it hasn't 
been more trouble than it is worth, so I am very happy.

I am configured like so, though I will be moving my bayes onto my 
ramdisk soon.

What does your reporting say? If you train a "insert favorite spam here" 
message and then see more of them come through later are they showing 
Bayes scores?


Three years now I've asked Google why they don't have a
logo change for Memorial Day. Why do they choose to do logos
for other non-international holidays, but nothing for

Maybe they forgot who made that choice possible.
