No bayesian for me?

	Here is an update: I wrote a script that through all the virtual email 
accounts (/var/spool/vmail/domain.com) and scanned the spam (placed in 
the .Spam folder) and the ham (placed in all the other mail folders). 
Since I am running it as postfix:postfix and that directory is owned by 
virtual:virtual, I did not get everyone. Is there a way to let the 
postfix-owned script check all the mails in the virtual-owned ones? Make 
postfix part of the virtual group? I think that is what the sticky bit 
is for, right? In any case, here is the output:

postfix at mail /etc/postfix $ sa-learn --dump magic

As you can see, there is a lot more ham than spam. I wonder how much 
harm would that cause in my bayesian filtering...

	Thanks for the suggestion! If I ever use MailWatch, I will try to 
remember to use that. =)
