No new feature needed, only a config addition.
I do not like to do it unconditionally on each mail in transit. because this header might be there on purpose. Yes, I can combine it with other ACL conditions to restrict it to submissing hosts etc. I only want to easy the configuration for the "assumed to be normal situation" when operating in submission mode. As in this mode Exim modifies the message in a way it otherwise wouln't be authorized to do. (IMHO) -- Heiko
