G Suite: Traffic Segmentation (Send Email from Selected Addresses to Paubox)

This configuration can be used to direct email from a subset of users out via Paubox, rather than directing all email traffic from your organization out via Paubox. This is done in the G Suite Admin Panel by creating a group of email addresses, host, and routing rule. 

Note: The complete setup instructions for Paubox Encrypted Email for G Suite are here. The  configuration below can be used in place of Part II: G Suite - Adjust Gmail Settings.

Note: This method CANNOT be used if there is an existing outbound gateway set in G Suite. 

A Paubox subscription or trial subscription is required (don't have one? sign up here!)
