You can find a deeper look into SPF syntax here. This is a basic overview of what an SPF record can contain. *You can find more information about the differences between fail and softfail here. +all – this tag allows any server to send email from your domain, so we advise strongly against it.
~all – (softfail) non-authorized emails will be accepted but marked*. all – (fail) non-authorized emails will be rejected*. In order to access your incoming messages, you need an email client: a program that can retrieve email from an email account, allowing a user to read, forward, delete, and reply to email. There can not be more then one incoming mail server for an email account. The “all” tag has the following basic options: The incoming mail server is the server associated with you email address account. It is important because it indicates what policy and how strictly it should be applied when a receiving server detects a server which is not listed (authorized) in your SPF record.
The end of the SPF record is the “all” tag.Also, ESPs typically publish SPF records for sending domains on your behalf, so you will want to verify with them as well. You should consult with these third parties to discover which domain to use as a value here. Next comes the “include” statement, which is needed for every third-party organization that sends email on your behalf.įor example: v=spf1 ip4:40.113.200.201 ip6: 2001:db8:85a3:8d3:1319:8a2e:370:7348 include:.The SPF version tag should be followed with all IP addresses that are authorized to send email on behalf of your domain.įor example: v=spf1 ip4:40.113.200.201 ip6: 2001:db8:85a3:8d3:1319:8a2e:370:7348.It will always be v=spf1, as other SPF versions have been discontinued.
