mailheaders to SMS enabled mobile phones

[Jon7800]

I'm trying to write a form to to send text messages to cell phones. Everything works fine except the phone sees it as coming from localhost@root OR whatever I specify in the php.ini file. (it is a windows box). I am using the following code:

$to = "$[e-mail]";
$subject = "test";
$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=utf-8\r\n";
$headers .= "From: $[e-mail] <$[e-mail]>\r\n";

mail($to, $subject, $txtMessage, $headers);

Now, when I send this mail to a regular email client such as outlook, it shows up as coming from $[e-mail] (correct as it should be) However, when I send this to a cell phone, it shows up as originating from localhost@root OR whatever i specify in the php.ini file. This makes it so that the phone cannot reply to the sender.

When I send the phone a text from Yahoo, it shows up as [e-mail], so I know the phone is capable of recieving headers.

Any ideas?? Any help is appreciated.
Thanks! -Jon

try adding a Reply-to:
header in addition to the from header

I did try that too, and basically it just stripped those headers away, and didn't show anything for them. It's very percular because it does work fine when sending it to a real email client such as outlook or even hotmail.
