(assuming all "to" addresses are in a single array, the html form would
have to reference all "to" fields as name="to[]")

$sendto = '';

foreach ($_POST['to'] as $address) {
	$sendto .= $address . '; ';
}

$sendto = preg_replace("/\; $/", '', $sendto); // cross fingers on reg_exp
here; might need to be \;\s$ instead of \; $
