What the documentation says4Technical articles
Documentation from dmarcian explains that "neutral" means that the domain owner isn't asserting whether the IP address is authorized to send email. They suggest checking the SPF record for syntax errors and ensuring that all authorized sending sources are included.
Documentation from Microsoft explains that the most common cause of problems with SPF is incorrect TXT record syntax and they advise that you check your syntax carefully.
Documentation from Google explains that SPF Neutral (spf=neutral) means the domain owner asserts that they might not be willing to assert that the message came from who it appears to be. This can occur for various reasons, including a lack of an SPF record or a misconfigured record.
Documentation from RFC Editor explains that SPF records must adhere to a specific syntax, and deviations can lead to SPF failures or neutral results. Common syntax errors include incorrect use of mechanisms (e.g., 'include', 'a', 'mx', 'ip4', 'ip6'), modifiers (e.g., 'redirect', 'exp'), and terminators (e.g., 'all'). Ensuring proper syntax is crucial for SPF to function correctly.
