Greetings.

I have a web application from which I have the MX records of zoho Mail and those of Mailgun, with priorities of 10, 20, 50, 70, being 70 those of mailgun, it works correctly, but when I send automatic emails, from my APP, I don't get the emails associated with Zoho mail. Any other mail from somewhere other than the app goes into the inbox and mailgun emails go out correctly.

Does anyone know how to fix it?

PD: I use the DNS in Digitalocean
