To do this, the delivery MTA uses the filtering results and the configuration settings for relaying inbound and outbound mail. ■ Inbound MTA: The component that receives inbound mail and forwards it to the Filtering Hub for processing. ■ Outbound MTA: The component that receives outbound mail and forwards it to the Filtering Hub for processing.
