How can i configure my dns records to support zoho sites and zoho mail for my domain?

zoho sites required 2 records:

1. (cname)  mydomain.com >>  www.maydomain.com

2. (cname) www.maydomain.com >> zhs.zohosites.com

And zoho mail required the following 2 records:

3. (mx 10) mydomain.com >> mx.zoho.com

4. (mx 20) mydomain.com >> mx2.zoho.com

The first record and the third / forth records are conflicting!!

Is there a solution for that using only (A, CNAME, MX) records?

Thanks.
