A brief DMARC primer

DMARC stands for Domain-based Message Authentication, Reporting and Conformance. What DMARC does is allow domain owners to publish policy statements in DNS telling receiver domains what to do with messages that do not authenticate. In addition, DMARC introduces the concept of “domain alignment.” What this means is that the authentication has to be from the […]


Looking for some experiences…

… with A client of mine asked today if it was worth registering domains with as a whitelisting process. I’ve asked a few delivery folks for their feedback, but I was wondering what the broader email community thought. Does registering there help delivery to domains behind barracuda processes?

How difficult is it to get on whitelists?

Just how difficult is it for a small business that runs a highly compliant mailing system to find their way onto whitelists at the big freemail/spam filter providers?

  • Ongoing Yahoo delays

    I've been hearing from folks over the last few days that they're seeing an uptick in deferrals from Yahoo! The deferrals are not uniform.
