another email thing

[gene0]

Hi Guys
I am using PHP 4 on nix box.
I have client fillout form then I get a copy of info from form and I want to send client something just to say thank you and I will be intouch soon. What I have come up with send mail to me and then sends a copy to client that is the same thing I get and sends it from server name not my email address.

<div id="Layer1"><!-- validated tranport info -->
<?php
if(!$visitormail == "" && (!strstr($visitormail,"@") || !strstr($visitormail,".")))
{
echo "<h2>Use Back - Enter valid e-mail</h2>\n";
$badinput = "<h2>Feedback was NOT submitted</h2>\n";
}
if(empty($company) || empty($contact) || empty($visitormail) || empty($notes )) {
echo "<h2>Use Back - fill in all fields</h2>\n";
}
/* here we display bad input info */
echo $badinput;

$todayis = date("l, F j, Y, g:i a") ;

$company = $company ;
$contact = $contact ;
$subject = "Power Only";

$notes = stripcslashes($notes);

$message = " $todayis [EST] \n

$from = "From: $visitormail\r\n";


mail("my@email.com", $subject, $message, $from);

?>

/* send mail to client */
<?php
