TLS-RPT
A DNS TXT record (_smtp._tls.yourdomain) that asks sending servers to report problems they had making encrypted connections to your mail servers.
How this affects you
Like MTA-STS, TLS-RPT is about email sent to your domain. The reports tell you when a certificate or MTA-STS policy is wrong before it costs you incoming email. It doesn't change how Vaartix sends.
