My setup is as follows.
I have two Gmail accounts: a main Gmail account, and a secondary one that I have so I can use Google's SMTP server.
This SMTP server account is used whenever I need a server/script/IOT device/whatever to send mail to me so that I don't need to configure my main Gmail credentials (or more accurately, an app password) within the unsecured device.
My main Gmail account (say firstname.lastname@example.org) is setup to pull email from the SMTP account (say email@example.com) using the option "Check email from other accounts".
An example setup would be a cron job on Linux emailing me its run result. This would be sent to
firstname.lastname@example.org. The server is setup to use Gmail as an SMTP relay with credentials for
email@example.com and this works great.
However, in Sent for
firstname.lastname@example.org I see all the mail that is sent through
email@example.com. I have
Send mail as configured for this account too, however, I have unchecked the Alias option which I thought caused what I am seeing.
Is there a way to prevent
firstname.lastname@example.org sent mail from appearing in Sent in
