Question

What is the mail flow for Google Workspace after HENNGE One has been installed?

Answer

If you transmit e-mails from Google Workspace to Google Groups, the e-mails will be delivered to the individual addresses by deploying registered e-mail addresses in the group.
Mail delivery pathway (flow) differs according to the Google Workspace setting.

[Specify the HENNGE One IP address/ host on the Outbound Gateway settings]

HENNGE One goes through this pathway twice for a time before the address extraction/ a time after the address extraction.

1. The mail delivery flow for Google Workspace -> Group Address (before the address extraction)
   
   [Google Workspace] -> [HENNGE One] -> [Group Address]
   
   
2. The mail delivery flow for Group Address -> Each user address (after the address extraction)
   
   [Group Address] -> [HENNGE One] -> [Mail Box of each user]
   
   

[Specify the hostname of HENNGE One on the Outbound Routing settings]

HENNGE One goes through this pathway only before the address extraction.

1. The mail delivery flow for Google Workspace -> Group Address (before the address extraction)
   
   [Google Workspace] -> [HENNGE One] -> [Group Address]
   
   
2. The mail delivery flow for: Group Address -> Each user address (after the address extraction)
   [Group Address] -> [Mail Box of each user]
   
   

NOTE: The both actions via outbound gateway/outbound routing taken on HENNGE One Service shall be the target of filtering /archiving only “1. Before the address extraction.”
