What Is an SPF Record?

SPF lets a domain owner publish which servers may send its email. Learn how SPF works, its mechanisms and qualifiers, and the 10-lookup limit.

A step-by-step guide to setting up SPF: inventory your senders, build one TXT record, publish it at the root, test it, and migrate to -all.

DKIM lets receivers verify your mail is authentic and unaltered using a private key signature and a public key you publish in DNS.

Step-by-step DKIM setup: generate a 2048-bit key pair, publish the public key TXT at your selector hostname, enable signing, verify, and rotate.

DMARC ties SPF and DKIM to the visible From address, lets you set a policy, and reports who sends mail as your domain. Here is how it works.

A step-by-step guide: publish a monitoring record at p=none, read your reports, then ramp through quarantine to reject without blocking real mail.

A step-by-step guide to setting up BIMI: enforce DMARC, build a compliant SVG, get a VMC or CMC, and publish your _bimi TXT record.
