Exchange 2003 Event ID 3030 - Status Code of 5.6.1
I have a small distribution group email address setup in my exchange server that has three internal employee as members and one "contact" record member. The contact record is a contractor employee who needs to be copied on these emails (but obviously has a different email address than employees of our company). On certain occasions, especially with one particular customer, when an email is sent to the distribution list, the contractor complains that he never received the email, even though the internal employees do get the email. When I go to message tracking on the exchange server, I see that there is a NDR generated (though it does not indicated why or to who). When I look in the exchange servers Event Log (Application), I can see that when this email comes in, there is an error generator saying:
Event ID: 3030
Category: NDR
Description:
A non-delivery report with a status code of 5.6.1 was generated for recipient rfc822;contractor@hisdomai
The NDR is only occasionally generated with certain customers (always it seems with this particular customer) for the contractor's email address. Yet, the email is successfully delivered to our internal employees all the time. Any idea on why this contractor's email address is sometimes rejected? If have sent numerous test emails from my personal yahoo email account to this distribution list email, and it always successfully reaches the contractor employee. Even other customers are successful, but a few are not.

This 8-bit thing...I saw that on a few searches, but I didn't understand it. So could it be that the client who is initially sending this email has their email in some sort of older format and our contractors email server doesn't like this format? I just don't know where to troubleshoot this unfortunately. I suppose I should start by contacting the hosting company of the contractor's email server and see if they have any advice.
NRhode, I created my contact record just like the person in the article did.

hypercat, great suggestions! I removed his contact from the distribution lists and gave him a domain account instead (that in turn forwards to his real email address).
I know this is not a lot of help, but it somewhat explains why the message would be rejected sometimes and not other times. It's not the contractor's address that's the problem at all, it's the receiving email server that is rejecting the message because of a format issue. You could assume that on the receiving end there is more than one SMTP server and one (or more) of them doesn't support 8-bit MIME and the message only gets rejected if it happens to hit that server.
Unfortunately, I don't know of any way to troubleshoot this from the sender end. One thing you could try to resolve the issue would be to send the messages in plain text format and see if that goes through reliably.
