Yes. Create the namespace as described in

I know Courier has a non-standard feature that causes expunging messages
to move them to Trash mailbox instead of really expunging. Dovecot
doesn't support this feature and I'm not planning on implementing it. It
should be possible to implement a plugin to do it though.
But Thunderbird can be configured to handle deletion by copying it to
Trash, which should do pretty much the same thing. Are your users not
using this setting?
