Are you asking to check spf record of   email domain to check its validation like (to resolve issue of spam/junk)? if yes then there are so many sites who provide such details.
I am looking for an API or do we have the way to find it in Linux ie in the form of dnslookup or something similar

My system is set to go directly to the OpenDNS name servers for DNS resolution. However, the results I get from "nslookup" differ from what I get if I query the same name server from another machine with the same resolv.conf settings.

That leads me to believe that DNS info is being cached locally somewhere. I don't have bind or nscd installed.

Where is this caching taking place and how can I clear/flush it?

I used to have opendns set up as my DNS.

network manager still has opendns IP addresses in the relevant entry of the gui. Also /etc/network/interfaces has the opendns IPs.

However, this has stopped working and I appear to be using my ISP DNS

How do I get back to my previous situation of using opendns?
