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

  • sammy@yourdomain.com sammy@gmail.com

This will forward the emails from sammy@yourdomain.com to sammy@gmail.com

Hope that this helps!
Regards,
Alex
