[MM3-users] Re: Whitelist in mailman3: How to allow only ~400 e-mail senders in a file whitelist to send to a list?

Thanks.

I also found the trick by looking to my 20 old mailman2[sic] lists, in all of them I had already "@whitelist" present :-) In mailman3 I added @whitelist@my.domain.com to accept_these_nonmembers.

Works fine. Problem solved.
