如何在Hostgator上使用PHPMailer库

Question

I am using PHPMailer class to send emails from my contact form to my gmail account on localhost and it works fine. But when I upload it on Hostgator servers, I get errors when trying to send email. Do I use IP Address or Hostname and which port should I use? Please Assist?

PHPMailer class

require ("PHPMailer/PHPMailerAutoload.php");                      //including phpmailer class

    $mail = new PHPMailer();

    $mail->IsSMTP();                                      // set mailer to use SMTP
    $mail->SMTPDebug = 2;
    $mail->Host = "108.167.172.144  ";            //Server IP Address
    $mail->SMTPSecure = "tls";                     // Connect using a TLS connection
    $mail->Port = 587;                                //Gmail SMTP port
    $mail->SMTPAuth = true;                         // turn on SMTP authorization
    $mail->Username = "*********@gmail.com";  // SMTP username
    $mail->Password = "********";            // SMTP password

    $mail->From = "$em";                         //email of sender
    $mail->FromName = "$nm";                        //name of the sender
    $mail->AddAddress("********@gmail.com", "Patwan");        //email address of recepient and name
    $mail->AddReplyTo($em, $nm);                     //Address to which recepient will reply

    $mail->WordWrap = 100;                                   // set word wrap to 100 characters
    $mail->IsHTML(true);                                          // set email format to HTML
    $mail->Subject = "Contact  Form";    //subject of email

    $mail->Body = "Name: " . $nm . 
                  "<br>Phone: " . $phone . 
                  "<br>Email: " . $em .
                  "<br>Subject: " . $value .
                  "<br>Message: " . $msg ;

Answer 1

Host is 'mail.domainname.com'. Port is 465. Username is one of the email accounts you created on hostgator. Password is the email account's password. SMTPsecure is 'ssl'
