Email communication is an important part of any business. It is the primary way to stay in touch with customers, partners, and employees. However, email communication can also be a security risk if not implemented correctly. In this blog post, we will discuss DKIM, DMARC, and SPF records for email communication and why they are important.
“What the heck are these records”, you ask?
1. DKIM, or DomainKeys Identified Mail, is an email validation system that uses cryptographic signatures to verify that an email has not been tampered with during transit.
DKIM EXAMPLE: v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DERSDDFSAD4GNADCBiQKBgLKLKLhjiwKtN5rDmSOvMw6wu4Q6YfHUWndP7eoWFd63wUOLc0FvFASDFLQ5qaHOHpN3s5xBe0ageeoJgugIBcjYXY/nqK8FLC4Sp/Wwxkm9kdq1E4FASDLLWQ3cKTry4uIY5RTAWTkUfjiFmIs13mgDCxs5dCLYN+nzeI+ASDFASDASDQAB;
3. SPF, or Sender Policy Framework, is an email validation system that checks whether the sender of an email is authorized to send emails from the domain.
SPF EXAMPLE: v=spf1 ip4XX.XX.XX.XX include:spf.protection.outlook.com -all
DKIM, DMARC, and SPF records help to ensure that your email communication is secure and not susceptible to spoofing or tampering. By implementing these records, you can help protect your business and your customers from email security risks.
As you can see, DKIM, DMARC, and SPF are all important records for email communication. They help to ensure that your emails are not tampered with and that the sender is authorized to send emails from your domain.
How to verify if you have these records or not?
What to consider before adding these records?
Before you add the DKIM, DMARC, and SPF records to your DNS configuration, you should comprehend the following:
– The DKIM selector: This is the name of the DKIM key that will be used to sign your emails. You can use any name that you like, but it must be unique.
– The DMARC policy: This is the policy that will be used to determine what to do with emails that fail DKIM or SPF checks. The options are to quarantine, reject, or accept the email.
– The DKIM private key: This is the private key that will be used to sign your emails. It must be kept secret and must not be shared with anyone.
– The DKIM public key: This is the public key that will be used to verify DKIM signatures. It must be published in the DNS records for your domain.
– The SPF record: This is a list of IP addresses that are authorized to send emails from your domain. You should only include IP addresses that you trust.
Adding DKIM, DMARC, and SPF records to your DNS configuration can help protect your business from email security risks. By considering the factors above, you can ensure that your implementation is successful.
