Secure website support: Let's Encrypt
Why has FastMail requested a Let's Encrypt SSL certificate for my custom domain?
As more browsers move toward encouraging secure HTTP for all traffic, it's clear that in the future, users of our websites and file hosting features will need certificates to securely serve files over HTTPS. Without this support, browsers will make it harder for viewers to access non-secure content.
Toward that end, FastMail is in the process of integrating Let's
Encrypt support to our domain and file hosting
features. We will automatically generate a certificate for your domain using
the Let's Encrypt enrollment process. We do this by responding to requests for
/.well-known/acme-challenge/ for your domain.
The certificate is not yet being used to serve secure HTTP for your domain: we are in the process of preparing and testing our support.
When will secure HTTP for my domain become active?
We don't have a firm release date yet, but hope to enable this feature early in 2018.
