You should be compiling your message, because you have too many parameters in your mail()...

$message=$name."\n".$family."\n".$phone."\n".$address;
$sendmail=mail($to, $subject, $message, $headers);

On another note, it's scary you're not checking your POST variables for security purposes...

Here's one thread on how to do it with some different examples:

I highly recommend you check all POSTed data with a regular expression.
