In SBS 2003 I need to add a user with an email adress from an external domain.
I have added the user and changed his primary email adress to the external one. Sending emails from his account works fine, but when the POP Connector retrieves emails they just disappear. Event viewer reports successful retrieval, but emails never appear in his inbox.
Other users on the external domain will still be hosted from their ISP, so it is important that he still can send out emails to other users in the domain.
