Step 3: Sending Email Using PHP
Create a PHP script to send email using the mail() function. Here is a basic example:
<?php
$to = 'recipient@example.com';
$subject = 'Test email using Postfix';
$message = 'This is a test email message';
$headers = 'From: webmaster@example.com' . "\r\n" .
'Reply-To: webmaster@example.com' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
mail($to, $subject, $message, $headers);

You just need to replace the email addresses, subject, and the message with your information.
