Setting Up SPF To set up SPF, you need to add a TXT record to your domain's DNS settings. This record will list the IP addresses or hostnames that are authorized to send email on behalf of your domain. Example: v=spf1 include:_spf.google.com ~all
Configuring DKIM For DKIM, you'll need to generate a public-private key pair. The public key is published in your DNS records, while the private key is used by your mail server to sign outgoing emails. Most modern email service providers offer built-in DKIM support, simplifying the configuration process.
Deploying DMARC DMARC requires you to publish a TXT record in your DNS settings specifying your DMARC policy. This policy defines how recipient mail servers should handle emails that fail SPF or DKIM checks. Example: v=DMARC1; p=none; rua=mailto:dmarc-reports@yourdomain.com
Enabling BIMI To use BIMI, you need to have both SPF and DKIM properly set up. Then, you can create a BIMI record in your DNS settings that points to a SVG version of your logo. Example: default._bimi IN TXT "v=BIMI1; l=https://example.com/logo.svg; a=https://example.com/VMC.pem"
