[Dovecot] Deleted email does not appear in the Trash folder

Hi all

I seem to have this problem whereby if I delete an email, then the deleted email does not appear in the Trash folder.

I tried setting dovecot mail_debug = yes, but I find in syslog, mail.log etc that there is very limited information.

If anyone could assit, I would be most greatful.

Kind Regards Brent Clark

P.s. I use Thunderbird as the mail client
