Don't try to login as root. Use a human account.

Uh, I also have:

/var/log/mail.err:
Dec 17 18:48:35 dovecot: auth: Error: userdb(test00001,127.0.0.1): user not
found from userdb passwd-file
Dec 17 18:48:35 dovecot: imap: Error: Authenticated user not found from
userdb

When I check /mnt/dovecot/userlist.passwd, everything looks ok.

There is no userdb { driver = passwd } (please show `doveconf userdb`
output).
You can use doveadm to see if a user exists (if dovecot will find it in
the userdb): http://wiki2.dovecot.org/Tools/Doveadm/User
