But that is not what I mean. What is NOT allowed (by
the spec) is to have:
name IN MX 10 mail
mail IN CNAME some.mail.server
So you can have a CNAME pointing to MX, but not MX pointing to CNAME.
To be specific, a CNAME RR points to another name which could be an MX RR.
Apart from associated DNSSEC RRs, a CNAME basically overrides anything
else defined for that name.
