Hi devs! I've seen unsubscribe emails coming into the mailing lists now and then these days (both user and user-zh mailing lists).
Instead of telling the user to send emails to some specific email addresses again and again, can we allow user to unsubscribe by sending "Unsubscribe" directly to user mailing list? By doing so we can also filter out these emails to keep a cleaner topic lists in the mailing lists.
