Is any body know if there a free PhpScript for Auto responder in regular basis?
I have a save list of email address spam free but find quite take time to manage it by send mail manually..

The only way for an auto responder is via cpanel X, im not quite sure about a php script being made for it. Do you host on cpanel servers?
