I can send but can't receive emails - dmark and mx3 errors

hello,
I stopped receiving email on my account.

I can currently send but can't receive. I have checked the MX toolbox for that domain as you suggest and I get a couple of error messages. One of them is Dmarc invalid name and the other is mx3.zoho.com fail to connect. I have already set up the mx3 on my host which is DigitalOcean.

Thanks for helping me out.
