Using a GMail's routing feature within Google Workspace for Business, I am able to set forwarding emails to 1st@my.org to 2nd@my.org. But replying to that email on 2nd@my.org's email editor (on GMail webapp on my.org), the recipient of it sees the from field as 2nd@my.org, not 1st@my.org.
Is there a way for an admin in the above scenario to force 2nd@my.org to reply as 1st@my.org for the emails that are sent to 1st@my.org then somehow forwarded to 2nd@my.org?
I know each user can setup their GMail editor to customize send mail as (e.g. webapps.stackexchange.com#14902 and webapps.stackexchange.com#131235), but I'm asking admin's feature so that each user doesn't have to bother customizing their editor.
I'm aware that Google Workspace comes with multiple routing options. For now, I'm using Default Routing but other routing option can be considered. I'm an admin in a small org that uses Google Workspace for nonprofit.
UPDATE 2024/03/26 To clarify, the solution doesn't have to be implemented in Google Workspace's rounting feature.
