Viewing /var/log/maillog I get some information but cannot see which application generated that e-mail, nor the content of it which would likely allow me to see where it comes from.
Can anyone suggest how to track down the app so I can reconfigure the mail address?
Hold all delivery so you can examine the mystery message in the queue. I found this article on how to hold mail with Postfix:
This requires creating the file /etc/postfix/hold with a static hold rule and "compiling" it with the postmap command. Add a line to main.cf to use the new map.
