Generic Email Source: SPF-Identified Servers


Description

SPF provides a way to identify servers that are authorized to send on behalf of a domain. Authorization to send on behalf of a domain usually means the domain owner has a connection (either technical or administrative) with the server in question. Be aware that SPF-Identified servers may not be sending DMARC-compliant email.

Possible Action

Servers that are authorized using SPF are likely capable of sending DMARC compliant email. However, be sure to review SPF-identified sources to make sure SPF records remain accurate (all legitimate sources are authorized), and that SPF records are not granting unintentional authorization (in the case where SPF is authorizing unrelated servers).
