Mail() & Gmail

[millercj]

Using the attached code below I'm sending an HTML email using PHP. It works fine, except with Gmail. If the email is sent to a Gmail account the email contents are blank and sender is unknown. I've looked around and it seems there is some widespread issue but i haven't found an answer/solution. Any help or light shed on this would be great.

 

<?PHP
//lots of stuff before this including variable setting, which all are working properly

$to = $email;
$subject = 'Your claim is in process!';
$random_hash = md5(date('r', time()));
$headers = "From: The Insurance Agency\r\nReply-To: [email protected]";
$headers .= "\r\nContent-Type: multipart/alternative; boundary=\"PHP-alt-".$random_hash."\"";
ob_start(); 
?>
--PHP-alt-<?php echo $random_hash; ?> 
Content-Type: text/plain; charset="iso-8859-1"
Content-Transfer-Encoding: 7bit
