SMTP connect() failed. While Sending Authentication Email

Question

I'm Trying to send email via php by using php mailer, but it's showing SMTP connect() failed. here is my code. can't find out what is problem in that. if somebody help to track error it will be very helpful for me.

$mail = new PHPMailer;

$mail->isSMTP();                                   // Set mailer to use SMTP
$mail->Host = 'dds.uemtv.com';                    // Specify main and backup SMTP servers
$mail->SMTPAuth = true;                            // Enable SMTP authentication
$mail->Username = '[email protected]';          // SMTP username
$mail->Password = 'pssword'; // SMTP password
$mail->SMTPSecure = 'tls';                         // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587;                                 // TCP port to connect to

$mail->setFrom('[email protected]', 'title');
$mail->addReplyTo($email, '$name');
$mail->addAddress($email);   // Add a recipient
//$mail->addCC('[email protected]');
//$mail->addBCC('[email protected]');

$mail->isHTML(true);  // Set email format to HTML


$bodyContent = '<h1>Your Registration Completed. </h1>'
$mail->Subject = 'Verify Account- Rozgar';
$mail->Body    = $bodyContent;
if(!$mail->send()) {

    echo $data->msg = $mail->ErrorInfo;
} else {
    // echo 'Message has been sent';
    echo $data->msg="Please Verify Your Email Address";
}

The issue is in the log. Message from the SMTP server: "We do not authorize the use of this system to transport unsolicited, 220 and/or bulk e-mail". The code works, you're simply getting blocked by the SMTP-server. — Magnus Eriksson
I don't think that's the error, the error is down further where the 535 incorrect authentication data part is. — David Findlay
@DavidFindlay Oh, look at that. You're absolutely right: "SMTP Error: Could not authenticate." — Magnus Eriksson
Yes, that "We do not authorize..." message is just part of the "welcome" banner; it's not an error. — Synchro

There's probably nothing wrong with your code. The server you are using doesn't allow relaying without authentication. There's authentication errors in your log, so perhaps you're using incorrect credentials.
