I use http://blackholes.us/ as it lists all countries individually with complete IP blocks... each one of these is in itself a RBL list, e.g. I use korea.blackholes.us for example from this website as a complete RBL... it works very well. The 99.8% of my spam is blocked at SMTP via this method. -- Gary
