The answer is/was ...:
The SMTP Virtual Server was corrupted. The solution was to create a new
SMTP virtual server instance and the rest of the related/affected settings.
First, of course, I had to stop the old/default one. Once the new instance
was running I had to remember to adjust the SmallBusiness SMTP Connector to
use the new VS for bridging. It all seems fine now though I have no reasons
for the SMTP becoming corrupted. ...which is kinda scary since there is no
monitor of it should it decide to act up again
