Topology Planning will design how the existing mail flow will be modified to meet encryption and decryption requirements.
Topology Questions

- What will be the target of the mail?
- What ports will be used on the targets to receive mail?
- What rules will trigger the encryption of the mail?

- Mail flowing from Corporate mail server then to the Virtru Gateway for encryption then back to the Corporate servers for final delivery is the recommended mail flow. This will allow complete visibility into the mail delivery using existing procedures and policies.

Please Note: If you are using Google Apps for Business, the Google SMTP Relay Service may be an alternative means for final message delivery. Please note that this service has volume limitations.
