[Dovecot] How to configure Lazyexpunge plugin?

Hi,

I tried the plugin but it is not working. Am using virtual mailboxes.

I added the following in dovecot.conf then restarted dovecot. Please guide me to the correct configuration.

############################## namespace private { prefix = separator = / inbox = yes }

# namespace for lazy_expunge plugin: namespace private { prefix = .EXPUNGED/ separator = / location = maildir:~/Maildir/expunged }

protocol imap { mail_plugins = lazy_expunge }

plugin { lazy_expunge = .EXPUNGED/ }#################################
