Oops, sorry, I meant
     Send= Editor
       with
     Editor= your-e-mail,(YOURLISTNAME)
The effect is similar to Send=Private, but with the difference you noted
(i.e., with Send=Private, only the attempting sender gets the bounce,
while with Send=Editor the sender gets a message "Your message has been
submitted to <XX> for approval" and the Editor gets what is technically
an approval request but in practice, in this application, is a bounce).
In essence, all members of your list are editors, so they can all send
without further approval (i.e., intervention).  For anyone who isn't on
the list, the message is forwarded "for approval" to the first-listed
Editor, which you would set to your own address.
 
BTW, in addition to this security addition, I also recently changed all my
lists to
      Subscription= Open,Confirm
(i.e., addition of the "Confirm" option, which results in an e-mail to
someone subscribing or unsubscribing requesting confirmation with a
"random-looking" code).  This virtually eliminates problems with
nuisance subscriptions caused by forged addresses, since it is a lot
harder to intercept e-mail destined for someone else than it is to forge
e-mail to look like it came from someone else.
 
Also, I set
      Validate= Yes
which requires me to provide my password with "add" "del" "get" "set" and
other commands, to reduce greatly the likelihood of someone forging a
listowner address to do mischief, and
      Review= Owner
to prevent people from creating junk-mail lists from "review" commands
and in general increasing the sense of privacy for list members.
 
These restrictions have proven to have negligible negative effect
compared to the benefits and increased sense of security, and I would
recommend that all listowners consider adopting them for lists that are
nominally "open." To summarize:
      Send= Editor
      Editor= your-e-mail,(YOURLISTNAME)
      Subscription= Open,Confirm
      Validate= Yes
      Review= Owner
