Hi All, I did a spam black list check on my server IP address using this link (http://www.mxtoolbox.com/SuperTool.aspx?action=blacklist:126.96.36.199) and found that my sever IP address has been listed on the Backscatter.org. From what I understand It appears that Qmail accepts emails without checking if the address is valid then sends out a bounce back message to the fake email address that spam was sent from. And that's what got my server listed on the Backscatter.org. I really want to fix this but after spending an entire day searching on the net I am completely lost. My server is running Plesk v9.2.3 (FedoraCore 4) and would like to know if someone can point me in the right direction of what I need to do.
