Setting one FROM email for all notifications

Hello!

We are facing a weird issue of late. We have a production version of out OJS hosted on Reclaim, so whenever the notification/email is sent from Reclaim using university email address, our system flags them as spam.

We want to set a single FROM email address that is like ‘do-not-reply@xyz.com’ (we are using SMTP). I couldn’t find any resource to do so in the documentation. Is this possible? If yes, then how to do so and also, I read about the envelope_sender but that is different than what we need to do if I am right.
