When configuring Network Prevent for Email, what is the role of Mail Transfer Agents (MTAs)?

A Mail Transfer Agent is an email-routing component responsible for transferring SMTP messages between mail systems. In a Symantec DLP Network Prevent for Email deployment, the MTA routes email to or through the prevention detector so that message headers, body content, and attachments can be inspected against DLP policies before delivery proceeds. Depending on the policy result and configured response rule, the email can be allowed, modified, redirected, quarantined, or blocked. An MTA is not responsible for browser security, general packet monitoring, or firewall administration. Although the option uses simplified wording, the MTA enables the capture and inspection workflow by directing SMTP traffic to the DLP detector. Therefore, option C most accurately represents the role of an MTA in Network Prevent for Email.
