Hi, I have the following problem.

I used some emails in zoho because I did not have an email server configured. As soon as I finished configuring the server, I canceled my Zoho account to use only the emails from my server, but when I send an email, the following error appears:

Delivery to the following recipient failed permanently:

     centermusic@centermusic.net

Technical details of permanent failure: 
Google tried to deliver your message, but it was rejected by the server for the recipient domain centermusic.net by mx.zoho.com. [165.254.168.50].

The error that the other server returned was:
553 Relaying disallowed
