2.2.1.22 ValidateCert

The ValidateCert command is used by the client to validate a certificate that has been received via an S/MIME mail.

To validate a certificate, the server MUST verify that the certificate has not expired and has not been revoked. The server MUST walk up the certificate chain, verifying that each intermediate CA certificate has not expired and has not been revoked and that the root certificate is a trusted certification authority (CA). Certificate validation is particularly important for verifying signatures (for example, on S/MIME signed mail). The validation details are not within the scope of this protocol.

The ValidateCert namespace is the primary namespace for this section. Elements referenced in this section that are not defined in the ValidateCert namespace use the namespace prefixes defined in section 2.2.4.
