Generate the certificate request.

  • From the Administration Console, locate the Configuration/SSL Certificates dialog.
  • Select New -> Certificate Request.
  • Supply all information.
    Note: The 'Hostname' (DNS name of the server) MUST resolve to the IP address of your Kerio MailServer in order for the certificate to work.
  • View the request file by selecting the request, and Show -> request. The request information will appear in a separate window.
    Second step: Submit the request file (CSR) to Comodo.
  • Select any option pertaining to Apache. This is the format required for OpenSSL, which is used by Kerio MailServer.
