Temat: [exim] Generated address leaks in 'message/delivery-status' despite enabling 'hide_child_in_errmsg'
Hi

I'm using Exim to redirect email. I've set 'hide_child_in_errmsg' so that the target-email address does not leak. But it still does.

In the example below, the mail server MX.DESTINATION is handling the mails destined to the domain DESTINATION and forwards any message to INBOX@ACTUAL-DESTINATION.

It happened that ACTUAL-DESTINATION was not reachable for a while, so Exim wasn't able to deliver the message and created a bounce message:

Now, I would like to prevent INBOX@ACTUAL-DESTINATION from being leaked to somebody by Exim. (How) can I achieve that? Could this be considered a bug? Because I expected enabling 'hide_child_in_errmsg' to do exactly what I wanted.

Thanks,
Chris
