Why SPF Authentication Fails : None, Neutral, Hardfail, Softfail, TempError, and PermError SPF authentication failures can happen due to the following reasons: The receiving MTA fails to find an SPF record published in your DNS You have multiple SPF records published in your DNS for the same domain Your ESPs have changed or added to their IP addresses which have not been updated on your SPF record If you exceed the DNS lookup limit for SPF If you exceed the maximum number of permitted void lookup limit of.
Your flattened SPF record length exceeds the SPF Job Function Email List characters limit Given above are various scenarios of why SPF authentication fails. You can monitor your domains with our DMARC analyzer to get reports on SPF authentication failures. When you have DMARC reporting enabled, the receiving MTA returns any one of the following SPF authentication failure results for on the reason for which your email failed SPF. Let’s get to know them better: Types of SPF Fail Qualifiers The following are types of SPF.
Fail qualifiers each of which is added as a prefix before the SPF fail mechanism:“Pass “Fail” “~” “Softfail” “?” “Neutral” How do these matter? Well in a situation your email does fail SPF, you can choose how stringently you want receivers to handle it. You may specify a qualifier to “pass” messages that fail check (deliver them), “Fail” delivery, or take a “Neutral” standpoint (do nothing). Case : SPF None result is Returned In the first case scenario,- if the receiving email server performs a DNS lookup and is unable to find the domain.
