I have a question when setting up my SPF record. I would like to know if I set up an inclusion record in the SPF record it will also "include" the subdomains of that primary domain that I have included.
Let's take a look at an example in my doubt:
v=spf1 +include:example.com -all
Will this "+ include: example.com" be covered if my email is sent from subdomain1.example.com or subdomain2.example.com ???
I really appreciate your comments.
