What steps can be taken to troubleshoot and configure a mail server for PHP usage on a server?

To troubleshoot and configure a mail server for PHP usage on a server, you can start by checking the configuration settings in the php.ini file to ensure that the `SMTP` and `smtp_port` parameters are correctly set. Additionally, you can test the mail function in PHP by sending a test email to see if it is working properly. If the mail function is still not working, you may need to check the mail server logs for any error messages or consult with your hosting provider for further assistance. 

// Example PHP code snippet to send a test email using the mail function
$to = "recipient@example.com";
$subject = "Test Email";
$message = "This is a test email sent from PHP.";
$headers = "From: sender@example.com";

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