[Dovecot] Oops!

I was testing a new webmail client - like an idiot, against my own mailbox, instead of a test mailbox (or even a separate server) - and my Inbox got wiped. Fortunately I backup our mails nightly, so I only lost a couple from today.

No idea how the wipe occured - I didn't INTENTIONALLY perform a delete + purge...but it happened.

Is there a way of configuring Dovecot to ensure that any delete operation specified by a client results in a "move to Trash" as a precaution? Instead of relying on the client to perform it?
