The MTA adapter feature on FortiSandbox is a feature that allows FortiSandbox to act as a mail transfer agent (MTA) that can receive, inspect, and forward email messages from external sources. The MTA adapter feature can be used to integrate FortiSandbox with third-party email security solutions that do not support direct integration with FortiSandbox, such as Microsoft Exchange Server or Cisco Email Security Appliance (ESA). The MTA adapter feature can also be used to enhance email security by adding an additional layer of inspection and filtering before delivering email messages to the final destination. The MTA adapter feature can be enabled on FortiSandbox in an HA-Cluster, which is a configuration that allows two FortiSandbox units to synchronize their settings and data and provide high availability and load balancing for sandboxing services. However, one statement about this solution that is true is that the MTA adapter is only available in the primary node. This means that only one FortiSandbox unit in the HA-Cluster can act as an MTA and receive email messages from external sources, while the other unit acts as a backup node that can take over the MTA role if the primary node fails or loses connectivity. This also means that only one IP address or FQDN can be used to configure the external sources to send email messages to the FortiSandbox MTA, which is the IP address or FQDN of the primary node.
