Hi Zoho,

You have no PTR record for your secondary mail server.

ERROR: No reverse DNS (PTR) entries. The problem MX records are:
141.166.91.103.in-addr.arpa -> no reverse (PTR) detected
You should contact your ISP and ask him to add a PTR record for your ips

Please address this problem as soon as your technical team can.

Thanks
