I first heard about the Ashley Madison breach on July 15, 2015 in a post by Brian Krebs. I immediately wondered what the fallout of such a breach would be. Would Ashley Madison's new tagline be "1 million divorces and counting!" Would the perpetrators try to profit from the stolen data, perhaps through blackmail?

When you begin to work with DMARC, you realize just how important identifier alignment is. Identifier alignment forces the domains authenticated by SPF and DKIM to have a relationship to the "header From" domain.
This is the second in a new ongoing series for us that gives you the tips and tricks you need for successful DMARC deployment . Read the previous tip here.

DomainKeys, or DK, was a signing technique implementation which contributed/evolved into DomainKeys Identified Mail, or DKIM. Since development efforts shifted into working on DKIM in 2004, there have been many improvements and far broader adoption of DKIM in email services. All new uses of email signing should use DKIM rather than DK, as the accepted successor technology.
In response to the article on PC World, Yahoo email anti-spoofing policy breaks mailing lists, we want to take the opportunity to comment on the benefits of DMARC and the important role it plays in securing companies and consumers.
So you’ve heard a lot about this new thing called DMARC, but don’t totally understand what to do? You are at the right place! After all, at Agari we are the DMARC guys. (Someone said this to me at a conference recently. I think it deserves a t-shirt. ☺) If you take a few minutes to read on, we will help you understand why you should publish your business’ first DMARC record.

The companies—along with others such as financial-service companies Bank of America Corp., FMR LLC's Fidelity Investments and eBay Inc.'s PayPal—are hoping to create an environment that allows the recipient of an email from, say, a bank, to feel secure that it isn't a trick.
