Sample PHPmailer SMTP script for windows

Download php mailer from phpmailer site HERE

Download and extract the folder in domain’s required path. If plesk then root folder should be httpdocs.

So path will domain/httpdocs/PHPMailer 5.2.16

Create test php file like send.php and add following code in that.

require_once 'PHPMailer-5.2.16/PHPMailerAutoload.php';
$mail = new PHPMailer;
$mail->SMTPDebug = 2; # 0 off, 1 client, 2 client y server
$mail->CharSet  = 'UTF-8';
$mail->Host = 'localhost';
$mail->Port = 25;
$mail->SMTPSecure = 'tls'; # SSL is deprecated
$mail->SMTPOptions = array (
    'ssl' => array(
        'verify_peer'  => true,
        'verify_depth' => 3,
        'allow_self_signed' => true,
        'peer_name' => 'Plesk',
$mail->SMTPAuth = true;
$mail->Username = '[email protected]';
$mail->Password = 'YOUR_PASSWORD';
$mail->setFrom('[email protected]', 'Name Surname');
$mail->addAddress('[email protected]', 'Name Surname');
$mail->Subject = 'Email subject';
$mail->msgHTML('Email content with html');
if (!$mail->send()) {
    echo "Mailer Error: " . $mail->ErrorInfo;
} else {
    echo "Message sent!";

Once done visit domain/send.php. and check if mails are working.
