customize amazons SES - remove amazonses.com

Question

I finally got SES to work, but now im confronted with another problem
The email sent leaves amazonses.com in the from and mailed-by fields like this
I am currently on sandbox access

from:    [email protected] via amazonses.com 
to:  [email protected]
date:    Sat, Jun 2, 2012 at 3:30 PM
subject:     Subject message
mailed-by:   amazonses.com

question: how can i remove amazonses.com from these 2 fileds and replace the 'mailed-by' field with my companies email address?

heres my php

function sendMail($to, $subject, $message, $from ) {
    require_once('sdk-1.5.6.2/sdk.class.php');
    
    $AWS_KEY = "********************";
    $AWS_SECRET_KEY = "****************************************";

    $amazonSes = new AmazonSES(array( "key" => $AWS_KEY, "secret" => $AWS_SECRET_KEY ));
    
    $response = $amazonSes->send_email(
        $from,
        array('ToAddresses' => array($to)),
        array(
            'Subject.Data' => $subject,
            'Body.Html.Data' => $message,
        )
    );

    if (!$response->isOK()) {
        return false;
    }else {
        return true;
    }
    return false;
}
sendMail('[email protected]', "Body message", "Subject message", "[email protected]" );

Answer 1

Since july 2012 it is easy to sign outgoing mail via SES itself.

Instructions are easy and straightforward.

p.s.: sorry for nekroposting, but this question is the one that popped up when I tried to do the same thing.
