Yes, the slave discards notifies, as I've seen in the log. Now can I (or
should I) allow notification from my internal slave, either by adding it as
a master for that zone or by adding it in my 'notifers' acl, which is used
inside the zone statement?
What I'd like to do is giving redundancy, but I'm not sure this is the
correct way to do it.

Well, no, the zone isn't really significant ( about 100 lines), but the idea
was fine. Actually, reinstalling bind9 solved this, so I guess something had
gone wrong when updating from 9.3.2 to 9.3.4.

Thanks for your answer too.
