problem with body using mail()

[theeper]

I am having a brain cramp, can someone tell me why the first example works, but not the second ? The first one sends the mail.

1

<?
$email = "[e-mail]";
$subject = "The subject";
$body = "Modern TwinComforter";
$headers = "From:[e-mail]";
mail($email, $subject, $body, $headers);
?>

2

<?
$email = "[e-mail]";
$subject = "The Subject";
$body = "Modern Twin Comforter";
$headers = "From:[e-mail]";
mail($email, $subject, $body, $headers);
?>

The only difference is the space between the words Twin and Comforter. It works without this space, but not with it. I know there is something simple I am overlooking here.
