I was under the impression that auto-clean folders only work against "known" folder names (such as Inbox, Sent, Junk, etc)
Can auto-clean rules be setup at the domain level to automatically purge mail after 10 days for ALL (current and future) users and ALL (current and future) folders ?
For example, if I setup auto-clean rule today at the domain level, and next week a user were to create a custom folder called "Email from Joe" via IMAP or Webmail would the auto-clean rule automatically include that new folder, or would we need to create a "one off" auto-clean rule for that "Email from Joe" folder?
