TLS >= 1.0

This really is not a good idea, otherwise we would be supporting SSL3 and earlier are “okay”.

RFC 8996: Deprecating TLS 1.0 and TLS 1.1

Skiff Mail won’t be added until they at very least have CAA or DANE, and a MTA-STS policy.

The fact they have not got one really says a lot about the authors. I think this is being plugged on social media, which is why it keeps getting suggested.
