Problem: I am using to my Centos/Exim/Cpanel server to relay emails. The person who receives my email sees a helo that captures my ISP IP address and lastly the mail server for my domain along with its IP.
My ISP (Verizon) IP is constantly being flagged as a spam source by a variety of RBL's. My domains have never sent spam and I only send a low volume of emails.
How can I remove my ISP helo IP address from being added to my outgoing email so that the only IP is the IP of domain sending the email?
