MTA-STS
A policy, published in DNS and on an HTTPS URL, that tells sending servers to deliver email to your domain only over an encrypted (TLS) connection with a valid certificate.
How this affects you
MTA-STS protects email sent to your domain, so it's about your inbox, not about sending with Vaartix. Set it up with your inbox provider. Pair it with TLS-RPT so you hear about servers that couldn't connect securely.
