The https://intodns.com/ shows the following error for a domain:
PLESK_INFO: Reverse MX A records (PTR) ERROR: No reverse DNS (PTR) entries. The problem MX records are:
22.214.171.124.in-addr.arpa -> no reverse (PTR) detected
You should contact your ISP and ask him to add a PTR record for your ips
PLESK_INFO: None of your MX record IP addresses have corresponding reverse DNS entries (PTR records). If these MX records are used to send outgoing mail this will cause them to trip anti spam filters. Many SMTP servers will not accept mail from an IP with no reverse DNS.
If Plesk DNS server is used, add PTR record for the domain using KB article 213934905.
In case an external DNS server is used, it is required to contact Internet Service Provider (ISP) in order to add appropriate PTR records.
Note: It needed to wait for the DNS propagation period. It may take up 48 hours, but mostly faster.
