I want to migrate to ZohoMail only some of the email adresses of my domain.

 

I want my email server MX mail.mydomain.com (priority 10) to bounce incomming messages that are not find mydomain to MX mx.zohomail.com (priority 20)

 

example.

In mydomain.com qmail server I have one only address A@mydomain.com

In mydomain at zoho.com I have only one address Azoho@mydomain.com

 

Actually a message to Azoho@mydomain.com does not arrive to MX at zoho because my primary email server rejects the message because it was not on his list of users.

 

At DNS I have
