Using the TLS protocol
Message archiving supports TLS encryption, which provides you with an option to enhance the security of your outbound journaled email messages. The TLS protocol over SMTP is a certificate-based authentication method that provides security-enhanced data transfers by using symmetric encryption keys. However, using TLS is not mandatory. With TLS encryption enabled, message archiving automatically accepts the encrypted messages, decrypts them and then stored in your archive. You can find detailed information about setting up TLS (SSL) for Domino Server at the IBM website.
Note: Using TLS is not required for setting up journaling, but it is recommended for security.
