You can't have a CNAME record for mydomain.org full stop.

You can only have a CNAME record if you have no other records for the
same label, and the label 'mydomain.org', being the top of your
delegated tree, will have SOA and NS records at least.

If you want to do this trick, you need to create a new name such as
www.mydomain.org as a CNAME record.

Then there's no problem creating an MX record for mydomain.org pointing
to myhostname.someddns.com, which is just as flexible as the CNAME.
