Use the addCustomHeader() method

Provides ability for user to create own custom headers (like X-Priority, for example).

Example use:

$mail->addCustomHeader("X-Priority: 3");

Why are you pointing links back to obsolete resources after I've corrected them? As the package maintainer I have to fight against this tide of crap every day. – Synchro May 01 '16 at 07:53

To parse the fields into an array (assuming your textarea is called mytextarea):

$headers = [];
foreach (preg_split('/[\r\n]+/', $_POST['mytextarea']) as $line) {
    list($name, $value) = explode(': ', $line, 2);
    $headers[$name] = $value;
}

var_dump($headers);

Then you can iterate over that array and process each header. Most of the headers you have listed require special handling, for example Subject should be put into $mail->Subject, not used with addCustomHeader. All that is covered in the PHPMailer docs and examples, so there is no point in expanding that here.
