Mail-in-a-Box and G Suite (former Google Apps)

Hello! I’ve been using Mail-in-a-Box for a while and I recently wondered the following,

Does anyone knows if it’s possible to configure G Suite to use Mail-in-a-box as the Inbound and Outbound gateway?

Please reffer to the following links,

Inbound: https://support.google.com/a/answer/60730?hl=en
Outbound: https://support.google.com/a/answer/178333?hl=en

Cheers!
