Have you at some point disabled NDRs on your hub transport [http://www.computerperformance.co.uk/exchange2007/exchange2007_ndr.htm], most likely to eliminate scatterback spam?

Thanks, transport rule worked.

We have a problem setting up a email redirect for a mailing list provider.<br />
<br />
The mailing list provider is using their server to send out marketing emails, using &quot;newsletter@ourcompany.com<wbr />&quot; as a sender address. In order to track down non-existent addresses etc, they want us to redirect all messages coming to &quot;newsletter@ourcompany.com<wbr />&quot; to &quot;tracking-email@maillistpr<wbr />ovder.com&quot;<wbr />. I've done it using the &quot;Mail contact&quot; functionality in Exchange 2007, but the problem is that NDRs are not forwarded. Out-of-office notifications, test emails are all forwarded out fine, it's just non-delivery reports that are not. When I check message tracking, it only shows a &quot;RECEIVE&quot; line and nothing else happens, so I suspect that Exchange is processing the message internally instead of forwarding it on. Is there a way to make Exchange forward those reports as well?
