Install certificates on Symantec Messaging Gateway (SMG)

Error: No stored certificate request matches this certificate.

Manage certificates for your system. The TLS certificate is used by MTAs in each Scanner appliance; the Control Center uses the HTTPS certificate for secure Web management; Domain keys are used for DomainKeys Identified Mail (DKIM) signing of outbound mail.

Solution: SMG will not install a certificate without either:

• the private key included in the PEM file
• a CSR that already exists in the SMG
