SPF "include" function question
Hello! I have what I hope is a basic SPF functionality question. Let's say I have mydomain1.com and mydomain2.com and both have SPF records set in DNS. Now if I put an "include:mydomain2.com" in the mydomain1.com SPF records, does that mean that any IP address in the mydomain2.com SPF record is included in the SPF record for mydomain1.com as a result?

David gave me a great way to see how everything breaks down in my SPF records, and Mahesh gave me the very specific answer I needed!
Note - add included lookup of domain1 or domain 2 only if they really used to send emails on behalf of, else separate SPF records should be configured for each domain
