Why Does SPF alignment fail? Case : Your SPF alignment mode is set to strict SPF alignment failed While the default SPF alignment mode is relaxed, setting a strict SPF alignment mode can lead to alignment failures if the return-path domain happens to be a subdomain of the root organizational domain, while the From: header incorporates the organizational domain. This is because for SPF to align in a strict mode, the domains in the two headers must be an exact match.
However, SPF alignment will pass if the two domains Job Function Email List share the same top-level domain for relaxed alignment. SPF alignment failed Shown above is an example of a mail that shares the same top-level domain but the domain name isn’t an exact match ( the Mail From domain is a subdomain of the organizational domain company.com). In this case, if your SPF alignment mode is set to “relaxed”, your email will pass SPF alignment, however for a strict mode, it will fail the same. Case : Your domain has been spoofed A very common reason for SPF alignment failures is domain spoofing.
This is the phenomenon when a cybercriminal takes over your identity domain name or address to send emails to your receivers. While the From: domain still bears your identity, the Return-path header displays the original identity of the spoofer. If you have SPF authentication in place for your forged domain, the email inevitably fails alignment on the receiver’s side.
