I heard from an employee that they got an email when I was testing some features, specifically time off approval (and maybe other features too). I saw the email, and I'm pretty sure it was my fault since I put "testing" and random number in every field of the data.

I don't think this should happen. Since it's already happening, do you know why that's happening and how to turn off the email when it's running on local?

I'm using odoo 16 enterprise
