Countermeasures against spoofing emails, specifications for email encryption: What is DKIM?
Guarantee of the sender's authenticity and the integrity of the message content using public key cryptography!
On our company website, we introduce measures against spoofing emails and the specifications for email encryption. "DKIM" (DomainKeys Identified Mail) utilizes public key cryptography, where the public key is recorded in DNS, and the MTA signs the email using a private key. This allows the receiving MTA to verify the authenticity of the sender and the integrity of the email content. By setting up the record, the receiving mail server can determine whether the email was sent by a legitimate sender upon receiving it. Please refer to the related links for more information. [Contents] ■ Example of operation ■ If only the DKIM settings are configured, the processing is left to the receiving mail server ■ If the sender wants to control the processing, DMARC settings are necessary ■ Is S/MIME not sufficient? *Detailed information can be viewed through the related links.
