That is the user based solution. The list admin based solution is to add person@example.com or ^person(\+.*)?@example\.com to accept_these_nonmembers.
Thanks Mark. However, as others will probably chime in, this is still a per-user setting. IE I'd need to set a accept_these_nonmembers for everyone who uses the +tag email option. I was thinking that there should be some config option that would (and if i knew python a bit better I may have attacked this)
When mailman checks if this sender is registered, I'm assuming (sorry for the phpesque here): if (in_array($sender, $registered_users))
Well before doing this check, the registered_users array could be walked through foreach($registered_user as &$user) { $user = preg_replace('/(.*)+.*(@.*)/', '/$1$2/', $user); }
