SPF

    Sender Policy Framework

    Verfahren zur Prüfung zulässiger E-Mail-Absender-Server

    SPF uses a Domain Name System (DNS) record to define which mail servers may send email on behalf of a domain. Receiving servers can thus detect forged sender addresses. On its own SPF is not sufficient; only together with DomainKeys Identified Mail (DKIM) and Domain-based Message Authentication, Reporting and Conformance (DMARC) does effective protection emerge.
