Meaning of ‘DKIM’

Domain Keys Identified Mail, or DKIM, is a type of security technology used to protect emails from being spoofed and misused. DKIM is an email authentication method that verifies the identity of the sender by using digital signatures. It works by adding a special header to each outgoing email sent from the domain. This header contains a cryptographic signature that can be verified against the sender’s public key stored in the Domain Name System (DNS).

The purpose of DKIM is to help prevent malicious actors from sending out fraudulent emails that appear to come from legitimate sources. The process ensures that incoming mail has not been tampered with and is coming from an authorized sender. In addition, it helps detect forged headers in messages sent out by spammers or phishers.

In order for DKIM to work, both the sender and recipient must have compatible software and use properly configured DNS records. The sender must have their private/public key pairs generated and published in DNS records associated with their domain name. They also need to configure their mail server to add the digital signature when sending out an email message. On the receiving end, the recipient’s mail server must have a copy of all valid public keys associated with domains they receive messages from in order to verify authenticity of any incoming messages through DKIM verification process.

When an email passes through a DKIM-enabled system, it will add two fields: one containing the signature itself, called “DKIM-Signature”; another containing information about where to find the corresponding public key, called “DKIM-Selector”. The receiving mail server will then pull up this information from DNS and compare it against its own record of public keys for that particular domain. If everything matches up correctly then it will trust that message as authentic and allow it through without any further checks or processing required.

By implementing DKIM technology on your mail servers you can ensure that only authentic messages are allowed into your network while keeping malicious emails out which could potentially cause serious damage or disruption if they were able to get past your security measures undetected. This makes it essential for businesses who rely heavily on email communication with customers or partners as well as anyone who wants additional protection against fraudsters trying to use their domain name for nefarious purposes.
