Why is it important to use the Reply-To field instead of the Absender field when setting up email functionality in PHP scripts, as highlighted in the forum discussion?

When setting up email functionality in PHP scripts, it is important to use the Reply-To field instead of the Absender field because the Absender field is not recognized by all email clients and servers. Using the Reply-To field ensures that replies to the email will be directed to the specified address, providing a more reliable way for recipients to respond to the sender.

$to = "recipient@example.com";
$subject = "Test Email";
$message = "This is a test email.";
$headers = "From: sender@example.com\r\n";
$headers .= "Reply-To: replyto@example.com\r\n";

mail($to, $subject, $message, $headers);
