What are the potential pitfalls of using the mail() function in PHP for sending emails, especially in terms of sender information?

When using the mail() function in PHP for sending emails, one potential pitfall is that the sender information can be easily spoofed, leading to phishing attacks or emails being marked as spam. To ensure that the sender information is accurate and legitimate, it is recommended to set the additional headers parameter in the mail() function to specify the From address. 

$to = "recipient@example.com";
$subject = "Subject of the email";
$message = "This is the body of the email";

$headers = "From: Your Name <your_email@example.com>";

// Send email
mail($to, $subject, $message, $headers);
