First time I was confused with custom DNS configuration with dynadot.com . I was also angry with them at support chat. Later On I discovered how to configure and get full dns server taste from dynadot.com Custom DNS.
I am giving here an example of a domain named example.com registered with dynadot and you have a server IP address 192.168.1.25. Login to dynadot account and go to Manage Domains and select Custom DNS server then First A record: Add A Record put IP address 192.168.1.25 Then MX Record : If you want to use mail server on the same IP Then Add MX record like this MX distance(10,0 or whatever you like on Priority basis) example.com
If you want to use mail server on the different IP Then Add MX record like this MX distance(10,0 or whatever you like on Priority basis) mail.example.com and Then ad SPF Record TXT Your SPF record [ you can create SPF record From mxtoolbox.com]
Now Subdomain Record I am adding for www,different mail ip ,DMARC and DKIM keys Add www A 192.168.1.25 mail A 192.168.1.24 _dmarc TXT "dmarc Values" _dkim_selector TXT " dkim values "
That's all . If you have further query Please contact dynadot support. Prepared by Md.Mesbahuddin Malik email address: mesbah.malik@gmail.com
