php mail function

Not sure if this will help...but this is the code I'm using to send feedback from a windows application. This php page is on teh internet and the windows app calls it and sends the feedback message and email address of the person...sends the email to two email addresses.

$emailBody = $_POST['message'];
$fromEmail = $_POST['from'];
if(mail("dan@blah.org,jessica@blah.org","Email alert: Feedback",$emailBody."\r\n\r\nfrom: ".$fromEmail)){
echo 'mail accepted for delivery';
} else {
echo 'mail was not accepted';
}

here is what I have, which is very similar except it does not work.  

<?php
$to = "me@mycompany.com";
$subject = "Hi!";
$body = "Hi,\n\nHow are you?";
if (mail($to, $subject, $body)) {
  echo("<p>Message successfully sent!</p>");
 } else {
  echo("<p>Message not sent!</p>");
 }
?>

Do you get a blank email? Or nothing at all?

also...are you using a local email server? or a remote one?

It is a local email server and I am getting nothing at all. The "message not sent" was echoed on the screen very quick, which makes it look like it is not even trying to send.

have you tried using telnet to test your email server/port?

yes and that works.

is the message being sent from an internal address TO an internal address?

yes

uncomment them obviously...

which file? php.ini or my php script file?

your script file...those lines will hopefully give you some error info to look at...
