I don't think the [log in to unmask] case is the same as the
East Anglia one.  I unsubbed M.R.Wrathall from about 4 list here when
mail bounced and have had no further activity.  I think the East
Anglia case is unique right now and from my reader it appears to
be active again.  I've asked the postmaster there for assistance.
