You can now forward outbound Gmail and Microsoft Exchange emails to your Proofpoint server and to encrypt them on their way to the target recipient whenever Enterprise DLP detects sensitive data. Encrypting outbound emails containing sensitive data prevents unauthorized individuals from reading these email messages.

Email DLP now supports inspection of .eml files and up to five levels of nested .eml email files. However, Enterprise DLP can only detect nested .eml files,—Enterprise DLP can't detect and inspect nested files in any other supported file types.

(Microsoft Exchange only) You can now configure Enterprise DLP to send an email notification to the sender of the outbound that matches the Email DLP policy rule. This enables Enterprise DLP to detect sensitive data immediately and notify email senders who their email wasn't sent out to the intended recipient due to a data security violation. As a result, the email sender knows about the block and can modify their email appropriately and attempt to resend it.

You can use the automated email notification feature only for Email DLP policy rules where the response Action is Forward email for approval to end user's manager Forward email for approval to admin, or Quarantine.
