dns auth check

We have hosted the application dns auth check in order to run this application in our online workstations with Wine or directly.

Quick description about dns auth check:

Zero-dependency Node.js CLI that validates SPF, DKIM, DMARC, BIMI and MTA-STS email authentication for any domain. Counts recursive SPF lookups against the RFC 7208 limit, auto-discovers DKIM selectors across 18 common providers, and grades the result A+ to F with fix suggestions. CI-friendly.
