how to send mail not junkmail

[crwtrue]

i have this code and it works even with hotmail but still some mail servers think my mails are junk mails. Code:

<?php

require("class.phpmailer.php");

$mail = new PHPMailer();

$mail->IsSMTP();
$mail->Host = "SMTP SERVER"; 

$mail->From = "SENDER";
$mail->FromName = "SENDBYWHO";    
$mail->AddAddress("TO");

$mail->WordWrap = 50;
$mail->IsHTML(false);

$mail->Subject = "Test";
$mail->Body  = "Hello!";

if(!$mail->Send()) {
   echo "Message could not be sent. <p>";
   echo "Mailer Error: " . $mail->ErrorInfo;
   exit;
}  

?>

Any ideas what could i do with phpmailer to get better results or is there some better php mailer class out there?😕
