google is your friend

Your outgoing IP needs to resolve with a reverse lookup. So you'll need a PTR record and an A record for your outgoing connection.

Hello,

These kind of issues are normally caused by a mismatch between your SMTP service name and the name returned when a DNS lookup is performed on the IP address.

Chances are the DNS Record, in this case a PTR Record for Reverse Lookup, is maintained by your service provider as they are responsible for the internet connection used by the mail server.

the reason for that is that your hostname in mail configuration do not have DNS A entry
