dkim cname records replication

You need to add “check-names ignore; “ to the zone definition when dealing with active directory.  That ignores the invalid underscore character.

Subject: dkim cname records replication

Hello List,

I have this question about replication.

I have a replication between BIND 9.9.5-3.
We try to make dkim work with Microsoft office 365. In the documentation they said that it should be a CNAME record with the sectors and it works in the master. The problem is in the slave, with the name and the underscore character.

I wonder if bind support the underscore character? Or if someone has link that help me.


Thanks in advance!
