Hi I have installed postfix and configured it using this tutorial: https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-postfix-as-a-send-only-smtp-server-on-ubuntu-20-04
The only problem is that I cant set a custom MAIL FROM or envelope sender.
Please help me.

Hello there,
May I ask if what you try to achieve is to send the emails from a custom mail address like address@yourdomain.com and not be marked as sent from the server’s hostname?
If that is the case you need to add the domain in the Postfix config file -
/etc/postfix/main.cf
and if you want to configure forwarding as well you can add the actual forwarding in this file -/etc/postfix/virtual
This will forward the emails from sammy@yourdomain.com to sammy@gmail.com
Hope that this helps! Regards, Alex
