I am trying to create a mail server. I bought the domain mastermails.info on godaddy.com. I am struggling with the setup of DNS. Whenever I change something in the MX record to make my server available for receiving emails by SMTP, I break something in the SPF record. Whenever I try to fix the SPF record, I get errors from the Kitterman testing tools, that it's not valid:
The TXT records found for your domain are: v=spf1 mx ptr ip4:126.96.36.199 ptr:mastermails.info mx:secureserver.net -all Checking to see if there is a valid SPF record. Found v=spf1 record for mastermails.info: v=spf1 mx ptr ip4:188.8.131.52 ptr:mastermails.info mx:secureserver.net -all evaluating... Results - PermError SPF Permanent Error: CNAME loop
I need help with the setup of DNS. My mail server is hosted on ip 184.108.40.206 with domain: mastermails.info. Here I want to have IMAP server and SMTP server. How to setup MX and PTR records to make it work? The biggest problem I have with reverse DNS not found error that I get whenever I want to send something by SMT using my mail server.
