What is this "Mail System Delivery Report" I got?
Some Time Warner Cable customers are receiving messages that look like this:

From: Mail Administrator [mailto:Postmaster@mail.rr.com]
Sent: Wednesday, January 30, 2008 4:24 PM
To: Customer Email Address Goes Here
Subject: Mail System Delivery Report

As part of the delivery process, your message was relayed to a machine which does not handle delivery status notifications. As a result, it is not possible to determine whether the message will get to its final destination. Please reply to <Postmaster@mail.rr.com> if you feel this message to be in error.

A likely cause of this message is that you sent a message to someone and you had "Receipt Requested" turned on, hoping to get an acknowledgement that your recipient received the message in question. Receipts such as this are also called "Delivery Status Notifications", and some mail systems are configured to not send receipts, due to local policy implemented there. What this message is telling you is that you sent a message with receipt requested to a site that does not provide such receipts.

I tried to send mail and it got returned saying "Not our Customer"; what gives?

This error message is not being generated by a Time Warner Cable mail server. Instead, some sites (such as comcast.net) choose the phrase "Not our Customer" to indicate that the intended address does not exist at that domain; more common phrases encountered in the same situation would be, for example, "User Unknown", "Mailbox Not Found", "Address Does Not Exist", etc.

In short, the error "Not our Customer" means that the address to which you tried to send mail does not exist at the remote domain.
