The Domain-based Authentication Details chart on the
Threat tab of Dashboard
displays the number of messages that failed Sender IP Match, Sender Policy Framework
(SPF),
DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting
&
Conformance (DMARC) authentication based on the selected mail traffic direction.
Sender IP Match is a way that readily enables you to simultaneously allow all
inbound email traffic from a particular domain while equally preventing spoofing by
manually
defining the allowed IP ranges. SPF, DKIM and DMARC are three email authentication
systems to
protect against email spoofing.
