Yes, it is a FAQ!  We noticed another thing about this.  If you have 
wisely changed the "listname-outgoing" alias to something not obvious 
(as recommended in the FAQ), there is something else you need to watch 
out for.

The owner of a list, or anyone with the password, can post messages to 
a moderated list directly, bypassing moderation.  You just have to follow 
the format given by Liz above.  But what happens if you short-cut it, and 
just use the following at the top of the body of the text?

What happens is that the message still goes out to the list, with the 
headers a bit jumbled.  But what is worse is that the headers now include 
another line called "Apparently-To:", and this line gives away your 
secret renamed "listname-outgoing" alias!  

Seems like the FAQ should warn of this possibility.  Better yet, would be 
a change to MD to prevent it from happening.
