External

In the External section of the S/MIME certificates panel you can view the public certificates of external persons (sometimes called "other people") - here defined as a person identified by an e-mail address which is not part of the DME system. Say that an external accountant sends a signed e-mail to the CFO of your company. The accountant's public certificate will then be extracted from his mail and stored here as the public certificate of an external person. Now every user in the DME system will be able to receive signed messages from the accountant, and DME users who have uploaded their personal certificates will be able to send signed and encrypted messages to the accountant without further setup, simply by selecting the appropriate functions in their client.

The certificates of external persons are automatically stored here, if the option Automatically store unknown certificates is selected in the Collaboration section of the Server configuration panel (see Collaboration).

Otherwise you can upload a public certificate by clicking the Import Certificates icon in the tab toolbar. If you do this, the imported certificates are trusted if their issuing certificate authority (CA) exists in the DME certificate store (see Root).
