Okay, When I send mail out via the mail()function, is it considered a relayed message? I guess, I don't really understand what a relayed message really is. I think I've got the headers right: $headers = "MIME-Version: 1.0\n"; $headers .="Content-type: text/html; charset=iso-8859-1\n"; $headers .= "X-Mailer: PHP4\n"; $headers .="X-Priority: 3 (Normal)\n"; $headers .="From: The Name<$femail>\n";
The thing is, one of my customers has a large opt-in base. When he mass mails them, they show up in my WHM stats as relayed messages. This worries me, as some of the messages are being rejected because they were relayed.
