mvanwyk Posted May 7, 2009 Share Posted May 7, 2009 Hi Guys. We host a merak pop3 mail server for a small town. This morning when trying to send mail to anyone using one or any of the domains we host we received this error message. <example[at]exampledomain.co.za>... Sender refused by the DNSBL bl.spamcop.net The mail server has a local IP address of 172.17.0.6 with a public Address 22.214.171.124. I check the Public address and noticed that it was not listed. Could someone please assist or point me in the right direction. I hope i have given enough information. Thanks in advance. Link to comment Share on other sites More sharing options...
