Easiest way is to use class.smtp.php form phpmailer using the following: $smtp = new SMTP if (empty($smtp->Connect())) return false; // Connect failure if (empty($smtp->Hello("yourmailerver.com")) return false; //Maybe not a mailserve if(empty($smtp->Recipient($to))) return false; //No such user $smtp->Close(); // Found user so abort transaction. return true; Tom
