PHP Email - My script has an error

[Osteel]

Hey everyone.

Ok so I have this simple Php script that simply sends an email. However, when I run the Php script online, it produces an error.

The Php script is:

<?php
$to = "[email protected]";
$subject = "Hi!";
$body = "Hi,\n\nHow are you?";
if (mail($to, $subject, $body)) {
  echo("<p>Message successfully sent!</p>");
 } else {
  echo("<p>Message delivery failed...</p>");
 }
?>

And the error is:

Warning: mail() [function.mail]: "sendmail_from" not set in php.ini or custom "From:" header missing in \\nas-001\winspace002\10-carsahoy.com\www\Personal\email.php on line 5

Now Im assuming from this error that Im missing the from portion of the email being sent out, and when I tried inserting one, it gave me more errors.

So could someone please show me whats going on?

Many thanks
