Add option to limit per user, posts per day or week
Moved from: https://bugs.launchpad.net/mailman/+bug/1465752
It would be very useful to add list options to limit the number of posts each subscriber can make per hour, day, week, or arbitrary time frame. Many lists have rules limiting subscribers to 2, 3, 5, or 10 post per day, but depend the honor system or on moderators to enforce the rule.
This has been implemented in GroupServer http://groupserver.org/groupserver/features/details/#postingRate
There is a script for this feature described here http://mailman.9.n7.nabble.com/To-restrict-sending-email-messages-per-day-td36569.html#a36617
