SPF (Sender Policy Framework) records are TXT records on your domain that authorize certain servers to send mail using your domain name. DMARC is a potent tool when it comes to stopping email spoofing. SPF none is treated as a fail in DMARC; the SPF authentication check failed, therefore, DMARC fails.

However, if an email is forwarded like in the email list scenario, SPF authentication can fail since the intermediate server's IP address is not on the SPF IP list. When this happens, and if no DKIM is set up, the legitimate email fails DMARC authentication since it fails both SPF and DKIM authentication, in which case, it's a false negative. In this case, DKIM check always fails and DMARC authentication result is up to SPF DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that uses SPF and DKIM to decide the authenticity of an email.

Note. Its an optional security protocol, and DKIM is not a universally adopted standard. In that case, the organizational domain's DMARC record will be used for all subdomains without an explicitly published DMARC record, by the DMARC policy discovery process. This means that without DMARC a sender has no say in whether a failing message is bounced, sent to a spam folder, or handled in some other way. How does DMARC work?
