That's not an X.400 address, but an X.500-type address, or legacy Exchange distinguished name (legacyExchangeDN).
Look for a setting in the user's properties of a munged alternate recipient.

Ignoring delivery to /o=org.name /ou=sitename /cn=recipients /cn=username Now this happens infrequently for a number of users (once every couple of days or less), however for one user, it happens almost constantly. Sometimes several of these events are logged in the event log at the same time. Perhaps this would be a cause for the server to lock up and need a reboot? The x400 address user also complains of failed delivery notifications from time to time, and external users also complain that they cannot sometimes send a message to them either. We have tested, but not been able to replicate the issue. The only thing that comes to mind is that this user also works at another company as well, and there was at one stage forwarding from one mailbox to the other. I have checked from our end, and we are not autoforwarding, and the other side does not appear to be autoforwarding either. I am not sure the best way to proceed from here, and havent been able to find much online yet about this issue. Any guidance you could offer would be appreciated. _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/read/?forum=exchange To subscribe: http://e-newsletters.internet.com/discussionlists.html/ To unsubscribe send a blank email to [EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
