Email Strict Transport Security: Our First Report

In EMAIL STRICT TRANSPORT SECURITY WITH MTA-STS I wrote about the challenges of setting up Email Strict Transport Security (MTA-STS). Here at Agilicus we believe in encryption for all, so much so that we’ve placed our domains in the browser preload lists. But, that left a hole in good old SMTP, which I resolved with that setup using a new pod on Kubernetes to act as the server/agent.

Today we received our first report, from Microsoft, showing that yes it is working. Good to know!
