Priority Actions 3 total Achievable: Secure
Medium Deploy MTA-STS policy

Publish an MTA-STS DNS record and host a policy file at https://mta-sts.openai.com/.well-known/mta-sts.txt. This tells senders to require TLS when delivering mail to your domain.

_mta-sts.openai.com TXT "v=STSv1; id=20240101"
Low Configure TLS-RPT reporting

TLS-RPT (TLS Reporting) sends you reports about TLS connection failures when other servers try to deliver mail to your domain. Helps diagnose MTA-STS and STARTTLS issues.

_smtp._tls.openai.com TXT "v=TLSRPTv1; rua=mailto:tls-reports@openai.com"
Low Enable DNSSEC

DNSSEC (DNS Security Extensions) cryptographically signs DNS responses, preventing attackers from forging DNS answers. Contact your DNS hosting provider to enable DNSSEC signing.
