SPF
The sender policy framework is one main thing within three levels of checks. Within those three types of checks, SPF is one of a kind that comes with a DNS TXT record. This record includes the specified record of IP address. Your server allows the sender to mail to your inbox only when the IP verification has been successfully approved. With this feature, you can secure your mail from the hands of a scammer. For example, if you run a business with more e-mail transactions, scammers might break through your mail and try to send e-mails on your behalf and intent with personal sourcing information. At this time, the SPF setting will trace out the IP address, and if the IP address does not match your official business location, it will bounce out of the mail.

- A third-party domain that has been authorized for using your mail on behalf of your domain
- An ending tag “all” should be included for the policy indication. And this policy indication detects and alerts server that’s not part of your SPF record.
KIM
Domain Keys Identified Mail is popularly known as E-mail Signing. This is similar to SPF, which comes with a TXT record. This DKIM is also added with your domain’s DNS record, and this works at the sender’s server and not the receiver’s server. Due to this difference from SPF settings, this is said as the seal of your mail and ensures the trust and safety of the receiver. DKIM serves as your customized signature, which anyone can’t modify at any time of mail transaction. It ensures that hackers or spammers have not modified your content. Altering the content of an e-mail with a resend option can change the complete game, and the scammer can fetch the information from the receiver, leading to a huge disaster.

- P: this denotes the actual public key, which will be recorded with your domain DNS
DMARC
Domain-based Message Authentication, Reporting and Conformance comes at final stage of three-level configuration that reports protocol built around the other two safety settings. The purpose of this DMARC configuration can be explained in three different ways:

The DMARC record’s creation involves a version tag like DKIM, including a policy tag. The additional benefit of DMARC record is that you can gain features of pct. Pct is the calculation that results in a percentage of a suspicious message that the over setting receives within a particular period.
