MX Plan and own SMTP server

Domains and Hosting
1

Goodmorning.

I have my domain with my smtp server declared in MX record of OVH dns zone.
When I migrate the domain from Aruba to OVH, I find MX Plan in my services.

Now I need to renew the domain.

I need to renew MX Plan to receive the emails on my mx server?

Thanks all
