CERTIFICATE

For an extra layer of security RiskFilter supports the use of TLS verification. This helps prevent devices such as non-trusted routers from allowing a third party to monitor or alter the communications between server and client. It also enables SMTP agents to authenticate each others identities, should this be necessary. The RiskFilter server can receive messages transferred over TLS and can also send messages via this protocol to particular domains.

For TLS to work, the domains that will use this TLS authentication must be listed in the Domain-based Delivery screen. Certificates are managed in the General > Certificate > Certificate Management screen.

•Once every week after the first notification.

•Every day during the last week before expiry.
