How can PHP be used to mimic the behavior of a mail server in terms of storing sent emails with proper headers for tracking purposes?

To mimic the behavior of a mail server in terms of storing sent emails with proper headers for tracking purposes, you can create a PHP script that captures the email content, adds custom headers for tracking, and saves the email to a database or file for later retrieval. 

// Capture email content
$to = "recipient@example.com";
$subject = "Testing email tracking";
$message = "This is a test email for tracking purposes.";

// Add custom tracking headers
$headers = "From: sender@example.com\r\n";
$headers .= "Reply-To: sender@example.com\r\n";
$headers .= "X-Track-Id: " . uniqid() . "\r\n"; // Custom tracking header

// Save email to database or file
$emailData = array(
    'to' => $to,
    'subject' => $subject,
    'message' => $message,
    'headers' => $headers
);

// Save $emailData to database or file for later retrieval
