What's the best permission settings for email php?

[undertoad666]

I have a contact form made in flash. This form uses php to pass the variables to my email address. I'm wondering what is the optimal permission settings for the php file. The following is the php file:

<?php
//echo phpinfo();
$email = "";
$message = "";
$name = "";

$email = $REQUEST['email'];
$message = $REQUEST['message'];
$name = $_REQUEST['name'];

$to = "[e-mail]";
$subject="Contact Form";
$msg = "$email\n\n";
$msg .= "$name\n\n";
$msg .= "$message\n\n";
$header = "MIME-Version: 1.0\r\n";
$header .= "Content-Type: text/plain; charset=iso-8859-1\r\n";
$header .= "From: ".$email."\r\n";
$header .= "Reply-To : ".$email."\r\n";
$header .= "Return-Path : ".$email."\r\n";
$header .= "X-Priority: 1\r\n";
$header .= "X-MSMail-Priority: High\r\n";
$header .= "X-Mailer: PHP4\r\n";

mail($to, $subject, $msg, $header);
echo "Message Sent";
?>

There is no "optimal" permission. It depends on who owns the file, and which user your webserver runs as. On a typical linux box Apache has it's own group (for example www-data on Debian) and your PHP scripts must have the read/execute permission for that group. A common octal permission is 0755 since you want full control of the file, and want your webserver to be able to read/execute it.
