The CommuniGate Pro Server implements a Certificate Server, issuing Certificates for its users.
A CommuniGate Pro Domain can act as a Certificate Authority for all its Accounts if:
To specify Domain S/MIME settings, use the WebAdmin Interface to open the Domain Settings pages. Open the Security page and click the S/MIME link. If the Domain has a valid Private Key, a page similar to those for the generic Domain Certificate are displayed. These fields can be used to enter a special S/MIME certificate for the Domain. This Certificate is used as the Issuer (Certificate Authority) for all S/MIME Certificates requested by users in this Domain.
If the special S/MIME Certificate is not specified, then the generic Domain Certificate is used as the Issuer Certificate.
