In that case you could be getting listed because of actions of the previous holder of that IP. That is a common source of DNSBL listings for IP addresses not currently engaged in bad activity.</div><div class="gmail_extra"><br></div><div class="gmail_extra">--Greg</div><div class="gmail_extra"><br></div></div>
