failed multi-view zone transfer

Notifications by default do not go to the server listed in the mname
field of the SOA record, so that the primary master does not notify

If you put the actual primary master's name in the mname, does it work

You saud that also-notify lists the slaves. This should ensure that
both slaves receive notifications, regardless of the mname value. If
that is not working, then it sounds to me like you've found a bug.
