Question About Dovadm syntax

Hello All,

I just have a quick question about doveadm commands.

1. Is there a command that we can use to count emails for a particular end user?

2. If an end user needed to copy/move emails from one account to another, is there a command?

Also, I've searched Google results, numerous Ubuntu, CentOS, Fedora forums, Doveadm forums, and read the DoveCot/DoveADM man pages numerous times and either I am over looking, or I am not understanding. Thus why I am asking here.
