PHP SMTP邮件需要在sitemailxchange.gate.com上配置我的代码是否正确

Question

我的代码是否正确或为sitemailxchange主机和端口号提供了一些建议..？我检查了大部分组合。 提前致谢。

    require("class.phpmailer.php");

    $mail = new PHPMailer();


    $mail->IsSMTP();

    $mail->SMTPDebug  = 1;
    $mail->SMTPAuth   = true;                  
    //$mail->SMTPSecure = "ssl";                 
    $mail->Host       = "smtp.sitemailxchange.gate.com";      
    $mail->Port       = 587;               
    $mail->Username   = "yourmail@domain.com";  
    $mail->Password   = "password";      

    $mail->SetFrom('yourmail@domain.com');

    $mail->AddReplyTo("yourmail@domain.com");

    $mail->Subject    = "PHPMailer Test Subject via smtp (Gmail), basic";

    $mail->AltBody    = "To view the message,  viewer!";     
    $mail->MsgHTML($body);

    $address = "yourmail@domain.com";
    $mail->AddAddress($address, "John Doe");

    if(!$mail->Send()) {
      echo "Mailer Error: " . $mail->ErrorInfo;
    } else {
      echo "Message sent!";
    }
