Sir, I believe you are right as the log entries stopped upon going to work today. Thank you for the sanity check. At home I was connected with Thunderbird running on my Linux system and at work I have the account added to my desktop Mac with Apple Mail. I do think it is a client issue at this point.

Unless you meanwhile managed to solve your issue I see none from my side. Should be client side else.
