MX Records are not updating for Zoho MX records

What is the name of the domain?

serano-catering.gr

What is the error number?

503

What is the error message?

Unable to send message;Reason:553 Reaying disalllowed. Invalid Domain - serano-catering.gr

What is the issue you’re encountering

I have properly set the MX records to point to zoho but they seem they do not work!

What steps have you taken to resolve the issue?

Deleted MX records and add them manually.
Delete MX records and set them automatically through zoho panel.

What feature, service or problem is this related to?

DNS not responding/updating

If this is what you’ve set them to, then your DNS is fine:

serano-catering.gr mail is handled by 10 mx.zoho.com.
serano-catering.gr mail is handled by 20 mx2.zoho.com.
serano-catering.gr mail is handled by 50 mx3.zoho.com.

Unable to send message;Reason:553 Reaying disalllowed. Invalid Domain - serano-catering.gr

The spelling is pretty bad on that. Is that the actual message? It’s likely that Zoho is not properly configured for email. Regardless, your DNS here is fine, and you’ll have to work with Zoho to resolve this issue.

Thank you for your reply!
There is some problem with zoho definitely.
Their DNS lookup tools shows the DNS working properly MX Lookup - Check MX records for any domain | Zoho Toolkit but on the admin panel it shows error for the MX records.
I have contacted them and waiting for their response.
