SPF Record (validated) not working.
We have a major issue here. We’ve added an SPF record to our domain and tried every possible solution with it including following two for which we believe both should work, one blocking any server and the other one blocking every server but the one associated with mx record - our second droplet’s mail server:
* “v=spf1 -all”
* “v=spf1 mx -all”
However, neither one of those work. We’ve tried the -all one first by trying to send an email from our server, and it went through without a bounce back, and we have received it on the other end. We then tried creating a whole new server and tried sending an email from there (this time using mx -all) and again - it did went through.
We’ve also tried having our domain (wehavebeenthinking.com.) as a host name instead of ’@’, as pointless as that may be - just to make sure.
We’ve also waited after each change for DNS records to get updated and checked it each time over whatsmydns.net
Please take a look below for our DNS setup for this domain. We’re going crazy over this and would appreciate any help on it!
