Authentication

DNSSEC

DNSSEC provides a way to ensure that the DNS answers a client is receiving from a DNS resolver are correct and have not been tampered with. DNSSEC must be configured at the domain's registrar and nameservers.

Learn more about DNSSEC.

SPF

Sender Policy Framework (SPF) authenticates email by checking the sending email server IP address against a list of domains provided by the SPF record of the envelope from domain. The SPF record can include other records, with up to 10 DNS lookups.

DMARC

Domain-based Message Authentication, Reporting, and Conformance (DMARC) ensures that the SPF and DKIM authentication mechanisms actually authenticate against the same base domain that the end user sees.

MTA-STS

SMTP MTA Strict Transport Security (MTA-STS) provides a way for domain owners to tell email services that they should only send email to the domain over a verified TLS connection to specific email servers. This prevents man-in-the-middle attacks when the sending email server supports it.

TLSRPT

SMTP TLS Reporting (TLSRPT) is a mechanism for sending email servers to provide statistics to domain owners about failures to establish TLS connections for SMTP. This allows domain owners to proactively identify TLS misconfigurations and man-in-the-middle attacks.
