Hi Paolo,
It is "20 most recently deleted mailboxes with the same path" So if someone delete/create/deletes "user/bovik/some_folder" over and over again, there will only be a maximum of 20 "DELETED/user/bovik/some_folder/<timestamp>" mailboxes on disk. The older ones are discarded. > 1) what happens if thirty users delete one mailbox each, all with > different names?

For each affected mailbox, there will be only the 20 most recently- deleted "DELETED/user/x...@example.com/.../<timestamp>" mailboxes on disk. The first 80 deletions will be gone.
