Why i was getting DNS error while connecting to cloudflare?

If you hover over the triangle it will tell you the reason.

Likely you have DNS entries that are not proxied that expose the IP address of a proxied record.

You’ll need to show the whole DNS page and give the domain for a full answer.

This was the full page and for our security I was try to hide ip address.

May I know how to solve this problem?

As I said, if you hover over the red triangle it will show you the warning.

It is likely warning you that the IP address of proxied records are also exposed by your MX record. Your MX record is pointing at rentalogue.in which is proxied. Since the MX record will be de-proxied by Cloudflare in order to make sure it works (Cloudflare can only proxy HTTP, not mail traffic) then this will expose your IP address as your mail and web servers are on the same IP address…

There is nothing you can do about this while mail and web servers are using the same IP address. It is only a warning so you can ignore it.

Also if mail.rentalogue.in is used by your mail clients to connect, you should change the DNS record to “DNS only” instead of proxied.

So, In MX record I need to change mail.rentalogue.in is it correct…?

Because web mails and webmail server was not working so need to change MX record mail.rentalogue.in then the mail server will work…?

No. In addition to updating the MX record, you also need to change the mail hostname to a :grey: A record containing the IPv4 address of the mailserver.

You also will want to evaluate why you have a second MX record that points to a hostname in another domain. Having two equally weighted MX records means that the sending mailserver will have to randomly choose which one will be sent the email. One of the MX records should be removed. Which one depends on where you expect your email to be delivered.
