E-Mail sucks! Your users just keep clicking the links in those damn phishing mails. And you can’t do anything about it. Hell somebody might be sending spam in your name and you have no idea about it. Let me blow your mind: You can solve these problems, for free. And I will introduce you the tools you need.
The cure to your E-Mail headaches hides behind three small acronyms:
- SPF: Sender Policy framework, tells others which mail servers are authorized to send E-Mail for your domain.
- DKIM: Domain Keys Identified Mail, uses encryption and DNS to verify an E-Mail sender and that it was not altered in transit
- DMARC: Domain based Message Authentication, Reporting and Conformance. Builds on SPF and DKIM and implements a policy and reporting system around them
