I am testing a setup with gsuite where the desired outcome is that Postfix keeps mailboxes for all accounts (those that use gsuite and some that don't). Postfix should also be able to send out emails.
The MX records point to gsuite and emails are received there. Gsuite is set-up to forward emails to Postfix which works alright for all external emails from other domains. The last remaining issue is that local emails coming from our domain and sent out through the Postfix server get delivered locally which means they will not appear in the Gsuite inbox.
Is there a way to force Postfix to send these mails through the internet as opposed to delivering them to the local mailboxes? I would prefer not having to set Postfix up to relay to Gsuite.
Postfix is set up with virtual mailboxes and I would prefer to keep the se-up as it is as much as possible.
