Different clients will send line breaks differently:

un*x -- \n
mac -- \r
win -- \r\n
??? -- ???

So normalize input before anyhting else.

<?php
function normalize_linebreaks($text) {
$text = str_replace("\r\n", "\n", $text); /* win -> un*x */
$text = str_replace("\r", "\n", $text); /* mac -> un*x */
return $text;
}

mail($recipient, $subject, normalize_linebreaks($_POST['text_area']));
?>
