Eric,
I checked dns records by doing an nslookup and found their were no mx
records pointing to back to us. They point to the external ip address that
they should. The address space for the smtp connector is set to * so that
all mail should be sent to the smart host who delivers the mail. The mail
isn't reaching the smart host however because exchange believes it can still
deliver this mail locally.
Don,
I'm a little confused by your post. I assume teh check box you are
referring to is the "automatically update email addresses based on recipient
policy". We no longer have any reference to the external domain in our
recipient policies. So are you saying that if there is one user who has the
above box unchecked and still has an address at externaldomain.com that this
will cause exchange to try and deliver all mail for the entire domain locally
instead of to the smtp connector to the smarthost. Because I can make up any
address joe@externaldomain.com or ted@externaldomain.com and it will still
try to deliver the mail locally on the exchange server. Is it really
possible that one user's properties can affect mail delivery for the whole
domain?

Have you verified that your smart host doesn't have a rule that points the
message right back at you? (You can telnet to port 25 and craft a message
to the domain in question, or message track the one you already sent to see
if it traversed the connector.)

No. If the email address in the user properties does not show the old
domain, and the smtp address is set correctly in the user properties you
should be ok. What I meant was if all users were updated and then set to not
update again, they may still have the old properties.
If the users now have mailboxes hosted somewhere else, delete their
mailboxes off the exchange server and mail should start moving. If users
have a mailbox, Exchange will assume that's where mail is suppose to go,
even though the address is wrong. In other words, if you create a mail
enabled user, and add his real smtp address, exchange will put the mail in
his mailbox, even though it should go elsewhere.

Hope It Helps!
