The history in my case is as follows:

Years ago, I used Outlook Express, and, for setting up NG access, they 
suggested an example email address: someone at microsoft.com.

I did not want to give my true email address, lest it be 'scraped', so I 
used: NOTsomeone at microsoft.com.  I added the NOT, to avoid misleading 
people.

Later, I was prevailed upon to change com to invalid.

List admins? This particular NG appears to be blessedly free of spam, 
but I hadn't realised it is moderated?
