Implementing SPF, DKIM and DMARC in M365
· 6 min read
I recently decided to take a look at how SPF, DKIM and DMARC actually work under the hood, whilst I've always had a rough, wishy washy idea of what the purpose was I never fully understood the implementation or what the records meant.
So I learnt, and what better way to implement the theory than to implement these records in my developer instance?
This post will detail the implementation process in a M365/Exchange Online only environment and won't touch so much on the nitty gritty of what or how.
