I like the idea about the cname. Can a cname be used as a
host for a MX record?
CNAME's can only be used for things that only have an A record. for example, you can't use a CNAME for a domain, which needs a SOA, A, NS, MX record.
Not sure if you are ACKing or NAKing?
Pdinc.us mx 1 smtprelay.pdinc.us Smtprelay.pdinc.us cname spamscan.google.com
Spamscan.google.com does have an A record, and ought not to have a MX, etc.
in general, CNAME's should be avoided except when absolutely neccessary.
