Sorry, haven't been following along... I discussed this several months back on the main list. https://mail.python.org/pipermail/mailman-users/2013-August/075523.html Basically I hacked a copy of find_member into scripts/check_subscriber: (http://paste.debian.net/hidden/c36ff81c/ ) check_subscriber is called by multiple postfix tcp_tables (one per list post addr in master.cf), such that incoming emails are checked against the membership list, and smtp rejected if not subscribed. Let me know if you want more details. -Jim P. _______________________________________________ Mailman-Developers mailing list Mailman-Developers@python.org https://mail.python.org/mailman/listinfo/mailman-developers Mailman FAQ: http://wiki.list.org/x/AgA3 Searchable Archives: http://www.mail-archive.com/mailman-developers%40python.org/ Unsubscribe: https://mail.python.org/mailman/options/mailman-developers/archive%40jab.org Security Policy: http://wiki.list.org/x/QIA9
