 In this session, we're going to discuss DMARC. DMARC is another method of providing validation of emails, which works in tandem with the SPF and DKIM that we've discussed in earlier sessions. If you go online and do some googling of what DMARC is, you're going to find a lot of information. But in short, it is basically another method to prevent jerks from spoofing emails. It does so by validating the alignment of your SPF and DKIM that you already have set up and basically builds on top of those technologies to provide a better method of preventing spoofing from occurring.
