I can receive email but none of my sent email is going through. It gets processed out of the Outbox and shows up as a Sent Item but no one receives our email. Do I have a localized black hole phenomena??? It is a very small network and I don't have any perimeter servers. I have no send connectors. Any guides to setting up a send connector (assuming that's what I have to do)? UPDATE: I set up a send connector and it seems to be sending MY mail (logged in as admin) BUT it is also placing a copy of every sent msg into the inbox of outlook. I can send email but ALL other users are being blocked with a "security" issue message.
