For a more permanent solution you can set:

service auth {
  unix_listener auth-userdb {
    mode = 0666
  }
}

You have multiple users with different UIDs, right? You need to run
doveadm as root then, so that it can change the UID when needed (and
then you don't also need to change the permissions above).
