NDRs on a normal basis during Exchange 2003 to Exchange 2007 during coexistence
We have begun moving mailboxes from Exchange 2003 to Exchange 2007 and are getting several NDR messages a day from both Internal and External sources to accounts that have not yet been moved.
I have checked a couple of these accounts, and they has no limitations on who can send email to them.
The issue here I believe is the hub transport server, as it had been inactive for the most part before the move. However the accounts on the Exchange Server 2007 do not seem to have this issue.
The size the mail stores is over 150GB so it will take more than a fews to get past this. Especially since they will only give us 6 hours/day to move the boxes.
Any ideas on what we are missing here?

So far it happens only when email is directed to users.
The 8bitmine ESMTP verb was on, when I telneted into the Exchange 2003 server.
I haved the removed 8bitmine ESMTP verb through ASDIEdit, and have verified that it is off now.
Waiting to see if it happens again.

Some additional information. Distribution lists do not seem to be an issue. However the issue with the outside email still is here:
#< #5.6.1 smtp;554 5.6.1 Body type not supported by Remote Host> #SMTP#
#< #5.6.1 smtp;554 5.6.1 Body type not supported by Remote Host> #SMTP#

Okay I've turned 8bitmime off on both sides as the Hub Transport was advertising it as well. However now there is a new error.
#< #4.4.6> #SMTP#, which to what I can tell, the message has exceeed its hop count for delivery.
Everything does comes in through the hub transport, but not everything is bouncing.

Can you confirm SenderID is disabled on the 2007 box at the moment ?
(I know I'm not helping much at the moment but if it was easy you would have fixed it by now!)

We use a smart host so SenderId is not enabled. All the spam control is performed outside of Exchange.

Also could you telnet to port 25 and type EHLO to show the avalable verbs lease as it could be an issue with 8bitmime.
