[MM3-users] How to separate bans for sending emails to lists and subscribing to them

Hi, Our requirements for using Mailman are that we can have non-members send an email to a list from any domain name, but only people who's email addresses match a list of specific domains should be able to actually subscribe to those lists.

I can't seem to find any way of doing this. Any ideas?

I have tried using the bans (global and on each list) but these appear to stop all subscriptions and emails being sent to or from a list if the address matches a ban.

Having moderated list subscriptions seems to be the only workaround, but this wouldn't be great if we could automate it (we are currently using Listserv which does allow us to do this)

Thank you,
