Repeating Peter, that would simply be a misconfiguration. RFC 1034, Section 3.6.2: "If a CNAME RR is present at a node, no other data should be present; this ensures that the data for a canonical name and its aliases cannot be different. This rule also insures that a cached CNAME can be used without checking with an authoritative server for other RR types." Let's imagine an additioanl RR to you example: www.example.net. MX 10 mail.somebodyelse.com Which MX should the nameserver return? Which one would be right?
