Configuring DKIM signing in MDaemon

DomainKeys Identified Mail (DKIM) is an open protocol for protecting email users against email address identity theft and email message content tampering. It does this by providing positive identification of the signer’s identity along with an encrypted “hash” of the message content.
To configure and use DKIM: 
  1. The system administrator creates a private/public key pair for the server and publishes the public key in the domain’s domain name server.
  2. Using the private key, the sending server creates a signature for each outgoing message. The resulting signature data is stored in a “DKIM-Signature” header within the message.
  3. The receiving server obtains the signature from the “DKIM-Signature” header and verifies it using the signer’s public key. Continue reading “Configuring DKIM signing in MDaemon” »
