Hello,
You can't mix CNAMEs with other record types.
The whole domain name can't be defined as a CNAME even if you don't
add any A/MX records to it because it *must* have NS records.
With BIND you can't even load a zone file defined like you suggested.
named-checkzone complains:
dns_master_load: domain.com.zone:14: domain.com: CNAME and other data
zone domain.com/IN: loading from master file domain.com.zone failed:
CNAME and other data
zone domain.com/IN: not loaded due to errors.
Interesting read: http://tools.ietf.org/rfc/rfc1912.txt pages 5/6 for CNAMEs.
Usually you should use something like:
domain.com IN NS dns.server.com.
domain.com IN NS other.dns.com.
domain.com IN A x.x.x.x
www.domain.com IN CNAME domain.com.
domain.com IN MX 5 etc
AFAIK, SSL certs for www.domain are also valid for domain by default
so that shouldn't be a problem.
