One reason to keep the list open to non-subscribers is gateways. The
sysadmins here urge people to use the Usenet mirrors rather than
subscribing ourselves (they are pretty responsive about creating new
ones as they are needed). The mirrors are one-way, so I'd have to send
mail to say linux-kernel @
edu rather than post to
However, it would be easy to extend Majordomo and other packages to
keep a separate list of approved posters. It might even be a subset of
the subscribers in some cases! A new command, "participate", perhaps?
"subscribe" should implicitly mean "participate", of course. Since the
list of participants is only used for checking, it doesn't matter
whether addresses in it grow stale, so it should mean little or no
extra hassle for the list manager.
PS. Please remember to use the majordomo list for majordomo-specific
issues in response to this.
