would be the correct one, as it says it is maildir format means anything
under Mail is your mail and imap will handle the rest

however this will impact Kmail if you try to read/write in same directory.
This is why my advise - rethink the whole setup.

Use
        mail_location = maildir:/var/spool/dovecot/%u/Mail
or similar

You would use Kmail as imap client and not as local mailbox reader ;-)
Forget that local reader part - you will use whatever imap client to access 
the mails from everywhere. This was your task correct?

log_path = /var/log/dovecot/dovecot.log
info_log_path = /var/log/dovecot/dovecot.info
etc
is set in /etc/dovecot/conf.d/10-logging.conf
