High
Escalate DMARC from monitoring to enforcement
Change your DMARC policy from p=none to p=quarantine (then p=reject). Review your DMARC aggregate reports first to ensure legitimate senders pass authentication.
_dmarc.isc.org TXT "v=DMARC1; p=quarantine; rua=mailto:dmarc-reports@isc.org"
Medium
Deploy MTA-STS policy
Publish an MTA-STS DNS record and host a policy file at https://mta-sts.isc.org/.well-known/mta-sts.txt. This tells senders to require TLS when delivering mail to your domain.
_mta-sts.isc.org TXT "v=STSv1; id=20240101"
