I route emails to proton mail via @duck.com email. This strips out all trackers and simplifies the email address. However, when I wish to write a new email, I have to use the email format 'recipientatdomain.com_yourduck@duck.com' in the ' sending to' field. I would like to have an option to put this into my proton mail settings once, and have the option to select this method as preferred routing. This does not have to be specifically for duck.com.
