not offtopic i think the dynablock would work very fine if everybody would provide them with information they need. Blocking dynamic ranges by a client of us (dynablock.easynet.nl) , rejected 2600 mail using relays.dsbl.org, blackholes.easynet.nl and some other filter rules kicked another 5400 out of 10000 emails After analysing the rejected mails we found 12 which are from 2 customer using an mailserver behind a dyn account. We talked to them, they configured the mailserver to send to the smtp server of the ISP, and the problem was solved.
We presented this results to the "Gesch�ftsleitung" and they are very happy about the effectiveness of this mechanism.
