PHPMailer ismail无法在bluehost中运行

Question

我使用bluehost作为我域名的服务器。我使用下面的代码使用PHPMailer发送邮件。代码没有通过错误并确认邮件已经消失。但实际上邮件不会发送给收件人。任何人都可以建议这里有什么问题吗？

        $Recpnt1='abc@gmail.com';
        $emailfrom = 'xyz@AlphaBeta.com';

        require_once 'PHPMailer-master/PHPMailerAutoload.php';

        $mail = new PHPMailer;

        //From email address and name
        $mail->From = $emailfrom;
        $mail->FromName = "AlphaBeta";

        //To address and name
        $mail->addAddress($Recpnt1);

        //Send HTML or Plain Text email
        $mail->isHTML(true);

        // Your subject          
        $mail->Subject = "Your confirmation link here";                          

        $message='ABCD';

        $mail->Body    = $message;

        if($mail->send())
        {
            $error = $error . "Confirmation link Has Been Sent To Your Email Address.";              
        }
        else
        {
            $error = $error . 'Cannot send Confirmation link to your e-mail address';
        }
