I am forwarding this to pkg-exim4-users to solicit the opinion of the user base. Origimal bug report not snipped to give the others full view of the request.

The rewrite rule rewrites also the recipient and the sender, which the normal headers_rewrite approach does not. I am also reluctant to add another headers_rewrite to both external transports. > I'm just surprised to see that the Debian exim4-config package > doesn't offer this choice.

I am reluctant to change the behavior of the package in a way that is so hard to understand. Implementing this will cause confusion with a lot of users. pkg-exim4-users, what do you think?
