answered in the FAQ, in the section titled "3.6 - How can I restrict a list
such that only subscribers can send mail to the list?".

Security by obscurity is not good security.
I'm blocking all email to *-outgoing in my mail server software (Postfix)
using it's regexp access lists feature. I have it return "550 Use list@domain
instead". There are ways (described in the Majordomo FAQ) to do this with
Sendmail as well.
