    environment:
    single Exchange 2003 mailbox server running on Windows 2003
    Single Exchange 2003 OWA server running on Windows 2003
    Sendmail running on RHEL for network edge servers

    This morning, one of our vice presidents sent out an e-mail to the all-staff distribution list, and received the following.

    The following recipient(s) cannot be reached:
    Robert R. on 12/2/2011 8:59 AM
    The message was undeliverable because the recipient specified has changed address permanently and forwarding was not applicable

    However, I did receive the message.

    There is no corresponding Non-Delivery Report or any other error in the Application and System event viewers for that time.

    Why would the sender receive an NDR when I received the message?

    According to Exchange message tracking, I was included twice:

    [email protected] and
    [email protected]

    We have both domain names, and e-mails to [email protected] is sent to [email protected]

    Like many users, my default SMTP address for my Active Directory object is [email protected]

    Exchange message tracking does show

    SMTP: Non-Delivered Report (NDR) Generated

    but no further details.

    And in all the entries for

    SMTP Store Driver: Message Delivered Locally to Store to [user]”

    I do not see myself listed, but given the large number of recipients, it’s easy to miss. Is there a way to export these message histories to text, so I can search the Message Tracking Events?

    UPDATE: OK, I did find

    SMTP Store Driver: Message Delivered Locally to Store to [email protected]

    in the Exchange message tracking history.

    Also, the universal list that this e-mail was sent to has 13 distribution groups as members, and I am a member of 3 of those groups.

    That NDR doesn’t look like an Exchange NDR. it is certainly not something I have seen before in the many years I have been using Exchange.

    Therefore I have to suspect that one of the recipients of the email has a forward to an external address enabled and that external address server has generated the NDR.

    Re: Message Delivered, But NDR Generated

    The recipient in question is me.

    So per your suggestion, I did check the e-mail properties of my Active Directory object, to make sure that forwarding isn’t enabled [which I should have checked before but didn’t]. No forwarding is enabled.

    It’s probable that at one time in the past, I had a test account or contact object with my name pointing to my G-mail account for testing purposes, but it’s no longer in Active Directory (unless there’s some hidden “cruft” somewhere).

    Since last week, two other people who have sent an e-mail to the all-employees distribution list have received the same NDR saying that the e-mail wasn’t delivered to me, even though I did receive the messages they sent.

    When they send an e-mail directly to me, instead of the distribution list, they do not receive an NDR.

    If it is only happening when the DL is used, then I suggest that you remove yourself from the DL and add yourself back in again.

    Done.

    Since it’s a system wide distribution list, I can’t send test messages.

    But I’ll let you know what happens the next time somebody sends a message to the list.

    Re: Message Delivered, But NDR Generated

    I removed myself from the distribution list last week, as noted above.

    Today, a message was sent to the distribution list.

    I did not receive a copy (no surprise), but the sender received an NDR regarding me again.

    This makes me think that there is some “cruft” in Active Directory, but I cannot find it using the obvious methods (ie, Active Directory Users and Computers –> search for “Robert R.”)
