What is the role of the Postmaster in PHP mail functions?

The Postmaster in PHP mail functions is responsible for sending emails from the server to the recipients. It handles the delivery of the email message to the specified email addresses. If there are any issues with sending emails, the Postmaster will typically generate error messages to indicate the problem. 

// Example of sending an email using the PHP mail function with the Postmaster
$to = "recipient@example.com";
$subject = "Test Email";
$message = "This is a test email.";
$headers = "From: postmaster@example.com";

// Send the email
if (mail($to, $subject, $message, $headers)) {
    echo "Email sent successfully.";
} else {
    echo "Email sending failed.";
}
