In fact, because of libnet-perl-dns missing on my sarge, all the rbl 
wasn't activated that's why I nedded to custom score rules.
But now RBL are activated, I better understand what you explain me.
A Lot of spam are marked with RBL ... good.

Just one last question about pyzor (& razor & dcc) :

As the fact it works on the hash of mail ... can I consider that if a 
mail is marked as pyzor-positive I can surely drop it ???

Thanks.
Sam.
