There actually is, it’s called dmarc and dkim records. The problem is that the companies don’t set up their domain names properly.
I checked the top 100 online retailers’ domain names recently and on 7 percent of them had their domain names set up, such as setting up dmarc records in their domain name to prevent email scams.
Pretty soon we will have NameBlock, and companies will be able to completely block certain scam domain names from even being registered, so that will help out a lot.
