The mailing list for listmasters using Sympa

[Steve Shipway <address@concealed>]

Just off the top of my head, maybe this would work --

is_editor([listname],[sender])                   smtp,smime,md5,dkim ->do_it
is_editor([listname],[header->X-Sender]) smtp,smime,md5,dkim  -> do_it
is_subscriber([listname],[sender])            smtp,smime,md5,dkim  -> do_it
true()                                                    smtp,dkim           
        -> request_auth
true()                                                    smime,md5           
       -> editorkey

This would allow editors and subscribers to post; non-subscribers would need 
to be authenticated (either via S/MIMEor challenge/response) and then would 
be forwarded for moderation.
