When I first ran into this problem after inheriting a zone with bad names,
I discovered that BIND would wouldn't accept A-records with underscores,
but WOULD accept CNAMES with underscores. I made a script which changed
the underscores to hyphens and then added a CNAME with the underscored
version. This gave time to phase out the bogus names while keeping BIND
happy. This still works fine with 8.2.3; I haven't any 9.x nameservers
