Outbound Email Security – Part 1 – SPF
September 4, 2015
Email, as a technology, has been around for longer than “The Web”. While one often hears about security for the web (in the form of encryption, tor, etc), rarely do people discuss email security. As with any technology there are many areas to “secure”, however this series will focus on outbound email security as it relates to anti-spam and anti-phishing. There are three key technologies in play, SPF, DKIM, and DMAC, so this will be a three part series. We’re going to be covering both the “How” (to set it up) along with the very important “Why” (you should set it up). Today we’re starting with Sender Policy Framework, or SPF.
