[MM3-users] Re: Does mailman2 regular_exclude_list equal mailman3 receive_list_copy ?

Do you plan to reintroduce the de-duplication feature so that if a mail list subscriber is on multiple email lists that are cc'd/bcc'd they only get the message one time?

Are you aware of solutions feature outside of Mailman3 core? Say filtering in postfix-mta? (might complicate tracking of dups in postfix)

For "mailman core", could we filter in outbound send of mailman? Example - could the processing pipeline be modified to track/discard duplicate msgs?
