In NoSpamProxy it is possible to request and revoke certificates via a managed PKI of an external certificate provider. In addition, certificates can be promoted to a domain certificate – also called gateway certificate – for your own domains or for partner domains. With a domain certificate, all emails are encrypted/decrypted or signed, depending on the certificate and direction, if there is no separate certificate for the recipient/sender.

Requirements:

  • The Encryption module is licensed.
  • Certificate provider is set up (for requesting and revoking).
  • Certificate can be used by the entire company (upgrade for certificate).

Request certificates (manually via user)

  1. Go to People and identities > Domains and users > Corporate users.
  2. Highlight the contact.
  3. Click Request cryptographic keys for selected users and follow the instructions in the dialog.

 

Request certificates (automatically via a user group)

  1. Go to People and identities > Domains and users > Corporate users.
  2. Click Automatic user import.
  3. Highlight the relevant Active Directory import and click Modify.
  4. On the Groups tab, highlight the Active Directory group and klick Add.
  5. In the dialog Automatic key request, select the relevant provider and confirm.

Each time an Active Directory import (scheduled or manual) is performed, the system checks whether a new certificate is required for a user in the group.

 

Revoking certificates

  1. Go to People and identities > domains and users > Corporate users.
  2. Highlight the contact and click Modify.

  5. Click Revoke.
  6. Follow the indstructions from the dialog.

Please note: The other end must always support this and allow the certificate to be used for it. If you have any questions about the certificate, please contact the issuing authority.
