Whenever I attempt to make a record for *.schneiderdonnelly.com.au and CNAME it, I get two errors:

• You can't mix CNAME/MX records together using the same hostname.
• Domain root's cannot be CNAME's, however you can web-forward this record to www.schneiderdonnelly.com.au instead for the same effect.

I've read it's possible so why can't I make it work?

I donated $5 to be a premium member and I've been trying to make it work for yonks.

I am prepared to swap DNS providers as long as they're free.
