Hello @ajinananth

This domain bitzburg.com does not have valid DKIM keys or none. Kindly create them for the domain by either creating a website or creating them manually
https://community.cyberpanel.net/t/how-to-manually-set-up-spf-dkim-and-dmarc-inside-cyberpanel/30666#installing-and-setting-up-opendkim-4

I’m using zoho mail for bitzburg.com

For email server we use bitzburg.in. we are tring to send email by bitzburg.in. ex, From: [email protected] to [email protected].

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

What do you mean

[email protected] mail is hosted in ZOHO.

[email protected] mail is hosted in our own server using cyberpanel.

When I send mail from [email protected] to [email protected] then the mail is rejected dut to “Mail rejected due to antispam policy”.

But when I send the mail from [email protected] to any other mail like gmail, its working

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.

I think you are not understand the problem,

Both domains are different one domain is .com another is .in

.com is hosted in zoho mail.
.in is hosted in cyberpanel.

I’m saying [email protected] is not sending mail to [email protected]

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.

This is configured properly, Kindly gothrough the first conversation, I have shared the screenshot of rDNS is properly configured, But in mail-tester.com, It says no rDNS configured.

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 - mail.mailserver.com should be the correct ptr record

This happened exactly after you updated ?

who is your domian provider?

godaddy is the domain 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.

I have attached the email received in gmail inbox(No Spam).

Kindly follow my advice. You are going round in circles.

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 domain.com not maildomain.com. You need to fix this

Sorry for more questions,

right now i’m getting this error when i send to zoho hosted email
