How to import a certificate into WorldClient

WorldClient’s web server currently does not support generating certificate requests. If you have IIS you can use its certificate wizard to create the request and import the response. WorldClient will then be able to use it. You do not need to continue to use IIS at that point, you can disable the service and continue to use WorldClient’s built-in webserver.

If you have purchased or otherwise generated a certificate from some source other than MDaemon, you can still use that certificate by using the Microsoft Management Console (MMC) to import it into the certificate store that MDaemon uses.

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” »
