smtp dane

SMTP DANE is a DNS-based email security protocol that helps protect against spoofing, tampering, and downgrade attacks by ensuring that SMTP connections are authenticated and encrypted. On WindowsForum.com, discussions focus on Microsoft's integration of SMTP DANE into Exchange Online, including new per-connector controls that allow administrators to set validation to Opportunistic, Mandatory, or None. The platform also covers the DNSSEC Enablement Wizard in the Exchange Admin Center and the relationship between SMTP DANE and MTA-STS. These features are part of Microsoft's broader push to make strong DNS-based email security the default for enterprise tenants, reducing reliance on manual configuration.
