Setting up SEP SBE, entered admin email address and left email server settings at default. Test email delivered successfully. After install to server and a handful of clients, I noticed "sending email failed" alerts after each client install.
We do not use Exchange.
Since, I have been experimenting with different settings for server, port, etc, none of which are working.
I have a support email into our email server provider, waiting a reply.
I guess my question here is, why did the test email during installation work?
