I'm testing Gmail as a smtp platform. It works great, but I seem unable to modify the From address using the setFrom() method.

$config = array('auth' => 'login',
'username' => 'myaccount [at] gmail.com',
'password' => 'mypassword',
'ssl' => 'tls',
'port' => 587);

$userNotification = new Zend_Mail_Transport_Smtp('smtp.gmail.com', $config);

$mail = new Zend_Mail();
$mail->setFrom('another [at] email.com','Another Email');
$mail->addHeader('another [at] email.com');
$mail->setReturnPath('another [at] email.com');
$mail->addTo($userEmail);
$mail->setSubject($usernotificationsubject);
$mail->setBodyText($usernotificationmessage);
$mail->send($userNotification);

I get a email with this "From:" header --> "Another Email <myaccount [at] gmail.com>"
instead of "Another Email <another [at] email.com>"

I tried :
$mail->addHeader('From','another [at] email.com');
but the execution fails with this line.

Is there any alternatives?

Thanks!
