This is actually configurable on the server side.  But you have to use
non-free web-interface to be able to set the option: ‘Settings’ →
‘Forwarding and POP/IMAP’ [0] → ‘IMAP Access’ → ‘When a message is
marked as deleted and expunged from the last visible IMAP folder’ =
‘Immediately delete the message forever’.

If you open ‘basic HTML’ interface that does not require non-free
Javascript, you will not see that option (as well as many others) in
settings dialog at all, as though it never existed.
