I'm very new to all things DNS, yet I am trying to set up some SPF records. So far the SPF Setup Wizard has been immensely helpful, and I think I have things pretty much set; however I'd really like to know what the difference between mx:domain.com and include:domain.com is. Is it somewhat redundant to have both? Or do they both do mutually exclusive things? Thanks in advance.

  • "include:" includes the settings from another SPF-record (must point to a different name) - it does not actually specify any hosts ifself.

  • "mx:" includes the hosts designated by MX-records for a domain name (same a using "a:" for each of the host names pointed to by the MX-records).

The 'include' directive allows you to import SPF settings from another zone. Imagine if you are a company that has 5-7 zone. Rather than writing the SPF records each time, you can just write them on one and import to the others.

Hope that helps!
