The mailing list for listmasters using Sympa

[Riccardo Veraldi <address@concealed>]

Hello,
i would like to use a scenario which reject all emails sent to a list 
unless the sender is the only one person who is allowed to send.
I can already do this with my own scenario but mails are forwarded to 
editor. I would like to reject without forwarding mail to editor.
is it possible to do ?
thank you very much

Rick
