Hey - Managing SPF RFC limits in large environments can be rather challenging - given the limit of 10 entries. (especially before you adopt DKIM)

Some vendors such as ProofPoint offer services such as SPF hosting, which allow you to work around this constraint. (https://www.proofpoint.com/au/resources/solution-briefs/proo...)
