We are currently migrating to Exchange 2003 from Lotus Domino 7. I have the Notes connector installed, directory synchronization is happening and mail is being routed between the two domains nicely. All inbound internet email is being routed through our Domino server and is correctly delivered to Exchange users.
However when an exchange user receives one of these external emails, our Notes domain name is being appended to the sender's address. For instance an exchange user who receives a message from firstname.lastname@example.org will show email@example.com@LOTUSDOMAIN in the To field instead.
This is causing problems when Exchange users reply to emails received from external senders.
Is it possible to somehow stop appending @LOTUSDOMAIN to all external email addresses?
