Set up comprehensive mail storage

As a G Suite administrator, you can ensure that a copy of all sent or received messages in your domain—including messages sent or received by non-Gmail mailboxes—is stored in the associated users' Gmail mailboxes.

For organizations that reroute messages to non-Gmail email servers, you can set up comprehensive mail storage to ensure that messages are stored in Gmail mailboxes for Google Vault archiving purposes.

You can also set this up if you have a non-Gmail system that uses the SMTP relay service to route messages on behalf of your users—for example, for ticket tracking systems, bug databases, or automated notification systems—and you want to display the messages in your users’ Gmail mailboxes. This is critical for storing messages in Google Vault for all users who enable SMTP relay.
