What is DKIM (DomainKeys)?
This blog explains what DKIM, or DomainKeys, is, how it works, and how it can help you prevent spam and fraud.
DKIM (DomainKeys Identified Mail) is a technology used to verify the authenticity of emails. This technology makes outgoing messages from your organization more trustworthy. The emails are digitally signed, so the recipient knows that the email actually comes from your domain. Want to learn more about various mail settings? Then also read our blogs about SPF and DMARC.
What is the purpose of DKIM?
The purpose of DKIM is to prevent spam and fraud by securing emails sent from a domain. By using DKIM, an email provider can confirm that an email actually originates from the domain name it was sent from. DKIM uses cryptographic principles to verify and confirm the authenticity of an email.
How does DKIM work?
The DKIM process begins with sending an email. This email is sent from a domain (www.voorbeeld.nl) and contains a DKIM signature. This signature is a code used to verify the authenticity of the email. The email provider checks the DKIM signature and compares it with the "public key" stored in the domain's DNS records.
If the DKIM signature matches, the email provider confirms that the email actually originates from the domain it was sent from. This means the email provider has verified the authenticity of the email.
Preventing cybercrime
Using DKIM is an effective way to prevent fraud and cybercrime. Thanks to the DKIM verification process, sent emails are more trustworthy and are less likely to end up in spam folders. Whether you're a large or small organization, it's important for everyone to use DKIM.
