Greetings,
For Exchange 2007, we would like to prevent external users from sending Read Receipt requests to our users. In the Outlook client, we can easily disable this. But for EAS users, their smartphones send a reply as soon as the email is opened. I've applied a Hub Transport rule to strip out the "Disposition-Notification-To" from inbound emails but this causes a different message to be sent to the sender, "Delivery to these recipients or distribution lists is complete, but delivery notification was not sent by the destination:". As a test, I've now also unchecked "Allow Delivery Reports" for Remote domains, but will this work? Should both settings be applied to avoid generating the response to senders as noted previously?
Thanks
