For email server we use we are tring to send email by ex, From: to

The mail is not sending only the mail hosted by zoho. Before it was working properly.

This is all wrong. What you are trying to do is impossible. Check the documentation you can only handle email delivery though zoho or cyberpanel choose one - Configure Email Delivery - Zoho Mail Setup

if you have set up local email delivery settings in your previous host, the emails sent from your previous email server will be delivered internally, and will not be delivered to your Zoho mail accounts.

Follow this guide to setup Achieve 10/10 Email score with CyberPanel! you need to setup rDNS ptr record for your mailserver etc. If you ran into issues kindly revert back here.

It was working properly before. we received the emails before.
I think this issue cause after update to latest version.

the rDNS is not configured correctly - should be the correct ptr record

This happened exactly after you updated ?

who is your domian provider?

The emails are working but, its only not received by zoho mails. The other emal providers its working fine.

Kindly refer the PTR for our IP.

We have to check with IP right not with domain?

Our IP is properly pointed rDNS.

But here they mentioned to set rDNS for domain name only right -

Honestly this is wrong. This is why you are getting errors during mail test here Email rejected by Zoho mail. If you read the rDNS error during mail test itself it states that your email was sent from not You need to fix this

Sorry for more questions,
