MTA-STS (Mail Transfer Agent Strict Transport Security)

Importance:

MTA-STS ensures that emails are transmitted over a secure (TLS) connection, preventing unauthorized interception and ensuring email integrity.

What We Do:

We publish an MTA-STS policy via a DNS record and host the policy on a public HTTPS endpoint. This enforces the use of TLS for emails sent to our domain, safeguarding against man-in-the-middle attacks.
