[Dovecot] Help configuring dovecot

[Spectron International, Inc.]

I installed Dovecot and OpenLDAP and at least now Dovecot is connecting to
LDAP and it seems to be getting all the information. My problem is that now
I'm getting the following error:

"mail process isn't allowed for root"

I changed the dovecot.conf file to use the dovecot account that the Debian
package creates:

login_user = dovecot
authuser = dovecot  #was root

and it still doesn't work. What does that error means? Directory permissions
wrong? Cant run as root? Root can't read mail? The important thing is, how
do I solve it?
