I am looking for free email (S/Mine) certificates and I was thinking about LetsEncript.
They offer SSL certificates for domains (homepages).
I also use these certificates for my domains/homepage. So I thought I could possibly also use this for the emails from you. I am satisfied with this certificate, which I could even automate creating and renewing the certificate on my server.
Does LetsEncript also offer this, if yes, where can I find the corresponding instructions?
