OK, that helps. It's my ISP's DNS, BTW (enough acronymns?) The 'localhost' refers to what (courierd?) was looking up, and the [::ffff:127.0.0.1] refers to what, then? I also have loglines that do not have 'localhost' but some other, external host and I still have (softdnserr [::ffff:127.0.0.1]). -- Ensign Walnut approaches Dr. Crusher with caution...
