PHPmailer odesílání emailů

Dobrý den, snažím se odeslat email s nastavením:

$mail = newPHPMailer(true);
$email = ‚zk********@centrum.cz‘;
$mail->SMTPDebug = 2;
$mail->setFrom(‚v****.o@seznam.cz‘, ‚Oxydesign.cz‘);
$mail->addAddress($email);
$mail->isSMTP();
$mail->Host = ‚wes1-smtp.wedos.net‘;
$mail->SMTPAuth = true;
$mail->SMTPSecure = ‚tls‘;
$mail->Port = 587;

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

$file_to_attach = $_FILES[‚file‘][‚tmp_name‘];
$filename=$_FILES[‚file‘][‚name‘];
$mail->AddAttachment( $file_to_attach , $filename );

$mail->CharSet = „utf-8“;
$mail->Subject = $subject;

a odpověď je
