HI Alan
I have outbound email disabled at the moment. If I enable the otbound email and look at the message as your article suggests then I see that the sender is service@paypal.com
I have raised the diagmostic logging to max for authentication. The application event log has many event IDs of 4006 and 3006

Neither error is going to help isolate the account.  The 4006 error is a problem sending mail to a domain and not sure about the 3006.

My article advises the error to look for.  It usually turns out to be an old account that hasn't been used for a while and the password is weak.

You could follow the advice in my 2nd blog by changing the Authentication methods (then restarting the SMTP service) and stop this from happening immediately.  You then should change ALL your passowrds to strong passwords and make sure you set them to be changed regularly.
