  • PHP uses php_open_ssl and php_socket extensions.

PHP Code for Testing:

<code class="php">$email = "youremail@gmail.com";
$to = "receiveremail@gmail.com";
$subject = "Hi!";
$body = "Hi,How are you?";
$headers = 'From: ' .$email . "\r\n".'Reply-To: ' . $email. "\r\n".'X-Mailer: PHP/' . phpversion();
if (mail($to, $subject, $body, $headers)) echo("<p>Email successfully sent</p>");
