Hello, I have a Dovecot 2.2.22 configured with mdbox storage.
THe server have about 50 mailboxes configured.Only in one mailbox I have a strange problem, sometime (in the last 2 month happens 3 times).
All the mail (Except INBOX) and all folders disappear. THe space on disk remain allocated. To this mailbox are connected 3 computers (2 PC Windows 10, and 1 Mac OS). I cannot determine who and why this happens to this mailbox. Can someone tellme how I can find the PC that delete all mail.
