MTA-STS enforce vs. testing: know before you switch

RFC 8461 defines two modes: testing and enforce

in testing mode, failures are reported via TLS-RPT but mail still delivers

in enforce mode, the sending server must abort if TLS negotiation fails

I always recommend at least 30 days in testing mode with TLS-RPT active before switching

the reports show you exactly who will break

no guessing required
