Today on Heavy Networking, all about improving email security with SPF (Sender Policy Framework), DMARC (Domain-based Message Authentication, Reporting & Conformance), and DKIM (Domain Keys Identified Mail). Our guest is Alex Blackie. He wrote an article on Email Authenticity 101 that I thought explained these topics really well. If you're a domain manager, you should listen to this one, even if you don't route mail through your domain. You can keep the bad guys from spamming in your name!
