Ready to Learn More about DMARC? Join Our Webinar with ExactTarget

If you have any interest in the latest news around email, email security, or phishing you’ve probably heard the buzz following up last week’s announcement of a new technology to help fight phishing and spoofing emails called DMARC (which stands for Domain-based Message Authentication, Reporting & Conformance). Along with all of the interest that we have seen both from the media and from the industry-at-large, I’ve still seen a fair amount of confusion around what DMARC currently is and is not. I wanted to take a couple of moments to help provide a bit more clarity on the topic as well as discuss some of the upcoming ways in which Return Path is helping to continually educate the email and security world on DMARC.

Remembering J.D.

This is the hardest thing I’ve ever had to write in 12 years as Return Path’s CEO. I hope it never has an equal.

One of our long-time employees, J.D. Falk, passed away today after a year-long struggle with cancer. J.D., which most people don’t know was short for Jesse David, was only 37 years old. Although I cannot claim to be a close friend of J.D.’s, I have known him fairly well in the industry going back about eight years, and he has been a trusted member of our team here for the last four+ years.

J.D. did great work for us at Return Path, but my admiration for him goes beyond that.

Rate Limiting with Sender Score

A number of our ISP partners have been using the Sender Score to inform their rate limiting algorithm, permitting IPs with a higher score to send at a higher rate, while those with lower scores are restricted to lower rates of delivery attempts.
