My mail server is not sending spam, why am I listed?
It is possible that spam is being sent via your server/network without your knowledge. It could be that you have a machine compromised with malware that is causing problems.
If you are certain that you are not responsible for the sending of any spam you may complete the IP statistics reset request form. However, if you are an ISP, Hosting Provider or you send newsletters via this IP you should sign up for the various feedback loops (FBLs) that ISPs offer. Reviewing and acting on the data generated by these reports in a timely manner will likely help improve your CSI reputation. https://wordtothewise.com/isp-information has links to the various FBLs that you can sign up for.
