Virtual Mailboxes redux

[@lbutlr]

I’ve created virtual mailboxes in dovecot, and they show up in various clients, but the folders contain no messages. (I will get an ‘empty” folder icon named “@virtual” and an empty folder icon named “month” inside it. Is there a way I can verify what dovecot THINKS should be in the virtual folder via doveadm?
