If a domain has a CNAME record, it MUST NOT have any other records of any other type whatsoever. So there's no way to set an SPF record for a CNAME domain only. IMO: It's OK for an SPF domain to be a CNAME, but again IMO each CNAME lookup should count against the SPF DNS lookup limit. Not sure how practical it is to do that. RFC 1912: 2.4 CNAME records A CNAME record is not allowed to coexist with any other data. In other words, if suzy.podunk.xx is an alias for sue.podunk.xx, you can't also have an MX record for suzy.podunk.edu, or an A record, or even a TXT record. Regards, Dianne.
