[Mailman-Users] Restrict by domain?

[Casella, Richard A]

Can't seem to find this in the archives.

Is it possible to restrict access to a list by my own domain?
Some lists I would like to have inaccessible to anyone outside
our domain (posting, subscribing, reading, etc).

I tried using the Privacy Options, hold post with header value
matching regular expression, but can't seem to get the syntax
for negating our domain.

Anyone have any ideas?
