About PTR & MX Records in Digital Ocean
I am going to deploy my next big project in DigitalOcean. Before going with DigitalOcean I just want to be clear on few things about PTR records.
I have read most of community answers related to PTR records. And, up to my knowledge (understanding as well), DigitalOcean configures PTR record based on *Droplets * name.
I have this scenario for my next project:
- I want to host my website in DigitalOcean Droplets (let’s say its IP is 22.214.171.124 with URL lets say (abc.co.uk)
- I want to set mail server in URL mail.abc.com.au and this is not in DigitalOcean and its IP is (let’s say) 126.96.36.199 in different server.
My Confusion is:
Should I name my droplets as “abc.com.au” or “mail.abc.com.au”?
And how do I configure A, MX, PTR records for perfect configuration so that there is no any issue related to spam and transaction of system generated mail (as far as I know, most of mail exchange services in these days do match dns and rdns for mail transaction (correct me if I am wrong))
