Hello.  I have a question regarding weighting / scoring of the spam filters.  I can not find a place where you can change the weight / score given to the spam filter score of an incoming e-mail when the address the incoming e-mail is coming from has previously had email sent to it.  It appears that by default the score assigned is -25.  I would like to increase this to around - 50 or - 100, but I can not find where to make the change.  

I would be very appreciated if someone could let me know where I can modify this value.

Thank you,

Dustin
