I'd like to remove the "Sender" header that Exim adds automatically to some outgoing messages. Ideally, I'd like to remove it from all outgoing messages (from local users and SMTP auth)
I've added "local_from_check = false" near the top of the config file. I know that will only handle local users, but it's a start. It doesn't help (perhaps it's in the wrong place?)
I also added "headers_remove = sender:x-mailer" in the "dnslookup" routers section. That seems to remove the "X-Mailer" header properly, but not "Sender". I'm guessing that the "Sender" header is added later (maybe at transport?)
At this point, I'm stuck. Help!
