<?php
$to       = 'example_name@example_mail.com';
$subject  = 'Testing sendmail.exe';
$message  = 'Hi, you just received an email using sendmail!';
$headers  = 'From: jordan.lorho@gmail.com' . "\r\n" .
            'Reply-To: example_name@gmail.com' . "\r\n" .
            'MIME-Version: 1.0' . "\r\n" .
            'Content-type: text/html; charset=iso-8859-1' . "\r\n" .
            'X-Mailer: PHP/' . phpversion();
if(mail($to, $subject, $message, $headers))
    echo "Email sent";
else
    echo "Email sending failed";
?>
