Solved Myself - Universal Email Abuse by Me
Using info found by searches on this forum I got the needed clue that a Universal Email problem caused the 6 error messages. When I turned off the emails the transaction completed successfully. I turned off the emails because I don't know how to make UE work. I posted details of my UE problem in the UE area. When I learn how to properly implement UE, I'll turn these emails back on.
