[RESOLVED] phpmailer problem

[Justa Lol]

i'm trying to configure gmail to send mails with using phpmailer and i'm getting an error:

Could not execute: /var/qmail/bin/sendmail

my code :

<?php
/**
* Simple example script using PHPMailer with exceptions enabled
* @package phpmailer
* @version $Id$
*/

require '../class.phpmailer.php';

try {
    $mail = new PHPMailer(true); //New instance, with exceptions enabled

    $body             = file_get_contents('contents.html');
    $body             = preg_replace('/\\\\/','', $body); //Strip backslashes

    $mail->IsSMTP();                           // tell the class to use SMTP
    $mail->SMTPAuth   = true;                  // enable SMTP authentication
    $mail->Port       = 25;                    // set the SMTP server port
    $mail->Host       = "mail.google.com";     // SMTP server
    $mail->Username   = "[email protected]";  // SMTP server username
    $mail->Password   = "password";            // SMTP server password

    $mail->IsSendmail();  // tell the class to use Sendmail

    $mail->AddReplyTo("[email protected]","Test");

    $mail->From       = "[email protected]";
    $mail->FromName   = "test";

    $to = "[email protected]";

    $mail->AddAddress($to);

    $mail->Subject  = "First PHPMailer Message";

    $mail->AltBody    = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test
    $mail->WordWrap   = 80; // set word wrap

    $mail->MsgHTML($body);

    $mail->IsHTML(true); // send as HTML

    $mail->Send();
    echo 'Message has been sent.';
} catch (phpmailerException $e) {
    echo $e->errorMessage();
}
?>

could someone please give me some detailed information on how to fix this? i can't really find anything useful searching with google..
