And this is exactly why i'm asking, i'm not sure what to make of the 
list, should it score positive or negative if a sender is in the list?

I have many contacts that use gmail and hotmail (my mail server users 
are mostly normal people, and not businesses), so i'm not sure that 
scoring their mails positively would be of much help.

The known_senders INC_MAIL_KNOWN_GLOBALLY symbol does not have a default 
score, so in returning to my original question, should I enable it at 
all?
