SPF failure occurs when the sender IP address is not found in the SPF record. This means the email is sent to spam or discarded.<\/p>\n

If DMARC is not implemented :-<\/strong><\/p>\n

<\/p>\n

<\/p>\n

SPF Softfail (~all) –<\/strong> The tilde \u201c~\u201d in front of \u201call\u201d means that any servers not listed in SPF record should be treated as a softfail, ie. mail can be allowed through but should be tagged as spam or suspicious.\u00a0<\/p>\n

SPF Softfail example:<\/strong>
v=spf1 include:spf.protection.outlook.com ~all<\/p>\n

In this case the include:spf.protection.outook.com authorizes Office 365 to send emails. Any emails originating from different servers should be marked as spam by the receivers.<\/p>\n

SPF Hardfail (-all) –<\/strong> The minus \u201c-\u201d in front of \u201call\u201d means that any senders not listed in SPF record should be treated as a hardfail. This means they are unauthorized senders and emails from them should be discarded.<\/p>\n

SPF Hardfail example:<\/strong>
v=spf1 ip4:192.168.0.1 -all<\/p>\n

In this case only the IP address 192.168.0.1 is authorized to send emails.<\/p>\n

<\/p>\n

<\/p>\n

If DMARC is implemented :-<\/strong>
DMARC ignores the nuances of softfail and hardfail in your SPF configuration i.e. ~all and -all are treated equivalently as a SPF fail.\u00a0<\/p>\n
