Evan writes, “Hi Al, My email address has just been compromised and now I am receiving hundreds of System Administrator and Mail delivery failure notices sent to my inbox from all those poor people who have received unwanted spam from my address. I noticed your name on the web when I went searching to find out how and if I can stop this happening and was hoping that you might have some ideas other than changing my email address?”Hey Evan, I’m sorry to hear you’re going through that. But don’t despair, this soon will pass. In the mean time, here’s what you should do.Change your email password, just to be safe. All throughout history, it’s been pretty unlikely that the bounces coming back from spam have anything to do with sending from your actual email account and email system. Do change that password, though, just in case. If a bad guy had…

This doubles the percentage increase seen in 2020, and reflects an acceleration of growth in the second half of the year. Starting with […]

The intent behind DMARC (Domain-based Message Authentication, Reporting and Conformance) is to give a domain owner insight into who is sending mail using their domain and allow that domain owner to define a policy to tell ISPs what to do with mail that purports to be from them but doesn’t pass authentication checks (usually meaning that said mail is fraudulent). There’s a strong implication here that this is a domain level setting, it’s something that you would do at the highest possible level for your domain. Meaning here, I’d set a DMARC policy for spamresource.com, not for subdomains like newsletter.spamresource.com or email.spamresource.com. And generally speaking, that’s what you should do. It’s what I (usually) do.But what if you want to get granular and do this differently with one or more (or all) subdomains of your domain name? Here are some options.Do nothing (at the subdomain level). Maybe you’ll set a…
In the first quarter of 2021, we took a look at DMARC adoption among Fortune 100 companies. We thought we’d check in on the Fortune 100 to see how they have progressed in the last year. The post Fortune 100 DMARC Adoption – Revisited appeared first on dmarcian.
DMARC’s utility as an anti-spoofing technology stems from a significant innovation—instead of attempting to filter out malicious email, why not provide people with a way to easily identify legitimate email? The post DMARC: Central Component of Zero Trust appeared first on dmarcian.

It can be hard to overestimate the importance of maintaining a healthy, clean, and relevant email list in digital marketing.

There are several causes for DMARC failure. To ensure your emails are properly authenticated and your domain is protected from cybercrime such as spoofing, it’s critical to understand what caused DMARC to fail authentication. When it comes to cyber-attacks, 2021 has shown how unprepared businesses all over the world are. Although Google tries its best to block over 100 million spam messages every day, companies have lost millions of dollars in financial losses due to cybercrime. Spam comes in all shapes and sizes, so why are we so concerned about DMARC email authentication? 94% of all malware is downloaded to a computer via email, and the majority of people are not able to distinguish between a well-crafted phishing email and legitimate messages. DMARC, along with SPF and DKIM, helps you monitor who is sending messages from your email domain and protects your customers from phishing, spoofing, and other email scams. As…
