[MM3-users] Only allow users to subscribe from certain domains

Does Mailman have anyway to just allow users to subscribe themselves to a list from certain domains... ie any user from test.com or test2.com

I do not believe this exists, but have a list manger who is asking. I feel they will have to either, approve all requests, or have a web frontend built that could filter that out and then send the subscribe commands in the backend.

Thanks
