Relay on external email
Posted on 2011-10-29
We wanted to prevent email, both internal and external, from being delivered to a specific user. So, using a test account, we Remove Exchange Attributes in ESM and ran the Clean Up wizard. This meant the mailbox was still there but orphaned. We then sent a test email to this user and on both internal and external senders receive an NDR as expected. Great, just what we want. We then brought the test account back on line by selecting Reconnect in ESM, and chose the account from AD. This process did not generate any errors. To test, we again sent test messages both internally and externally. What we didn't expect was that although the internal emails are delivered successfully, an NDR is returned to any external sender. Basically, this user can no longer receive external email. Any ideas?
