With ACL plugin enabled, the master user's ACLs are used. And your
master user has no ACLs, so nothing is shown. The proper fix for this
would be to set a default ACL for the master user, but default ACLs
don't exist yet. So you'll have to kludge this, by changing the master
user back to the login username. Try if this works:

userdb {
  args = uid=mailreader gid=mailreader allow_all_users=yes master_user=%u
  driver = static
}

Also don't set your home to /. Better not to set it at all.
