Add "ban user subscription" and "moderate user" buttons to moderation/subscription approval screens
A list admin writes: Probably the single feature from MM2 that I miss in MM3 is the option is to add a sender to the "discard"/"can't subscribe" list while handling the individual email. Is there a plan to bring such a feature to MM3? Or is our installed instance on mail.python.org out of date and this already exists?
