function socketmail($toArray, $subject, $message, $nombre, $email) {

ini_set(sendmail_from, $email);

$ipdir="172.16.30.4";
$puerto="25";

$connect = fsockopen ($ipdir, $puerto, $errno, $errstr, 30) or $mens="No se pudo conectar al servidor de correo!...";
echo $mens;
$rcv = fgets($connect, 1024);

fputs($connect, "HELO {$_SERVER['SERVER_NAME']}\r\n");
$rcv = fgets($connect, 1024);

while (list($toKey, $toValue) = each($toArray)) {

fputs($connect, "MAIL FROM:$email\r\n");
$rcv = fgets($connect, 1024);
fputs($connect, "RCPT TO:$toValue\r\n");
$rcv = fgets($connect, 1024);
fputs($connect, "DATA\r\n");
$rcv = fgets($connect, 1024);

fputs($connect, "Subject: $subject\r\n");
fputs($connect, "From: $nombre <$email>\r\n");
fputs($connect, "To: $toKey <$toValue>\r\n");
fputs($connect, "X-Sender: <[email protected]>\r\n");
fputs($connect, "Return-Path: <[email protected]>\r\n");
fputs($connect, "Errors-To: <[email protected]>\r\n");
fputs($connect, "X-Mailer: PHP\r\n");
fputs($connect, "X-Priority: 3\r\n");
fputs($connect, "Content-Type: text/html; charset=iso-8859-1\r\n");
fputs($connect, "\r\n");
fputs($connect, stripslashes($message)." \r\n");

fputs($connect, ".\r\n");
$rcv = fgets($connect, 1024);
fputs($connect, "RSET\r\n");
$rcv = fgets($connect, 1024);
}

fputs ($connect, "QUIT\r\n");
$rcv = fgets ($connect, 1024);
fclose($connect);
ini_restore(sendmail_from);
