Maybe you've already done this, but just to double check...

On the moderation tab you set a private incoming account, with a  
single word.  For example, if you have an list address of  Schools@mail....ukthen
  you want to define a secret incoming address like: secret     Then  
you provide the moderator's address in the lower part of the  
moderation tab.

Then to send a message to the list you send it to secret@mail...

The security is keeping the secret address, well, secret.  Anyone can  
a trigger an announcement email if they know the secret address.
