Can't send/receive mails even after mx records visible at third party tool

Can't send/receive mails even after mx records visible at third party tool

Hi,

I have configured mx records for my domain(buddycorp.in) as per instructions and verified in the third party website provided.
But still not able to send/receive mails on my account.
Am able to login to zoho mail with my credentials and compose a new mail to be sent, but not received on other side.
When I try to send a mail from other domains, getting message delivery error.
Request you to please provide suggestions in solving my problem.
