Bugfix
- [security] On Grav 2.0, email settings can no longer read your site, system or theme configuration directly, which was a way around the restriction added in 5.0.4 that already stopped them reading it through
config(GHSA-p597-crqc-m349). Requires Grav 2.0.16 or later, which is also where the underlying protection for email settings lives.
