What are the ways to Check SPF records on a domain?
There is a website where i can do it manually using - http://www.mxtoolbox.com/SuperTool.aspx
How can i do it
For what is worth - MailBee's .NET Objects support this as well. I only say this because we already owned this component and I was about to implement something else when I found this goodie already baked into what we had.
