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:
--------------------------------------------------------------------------
// headers removed
--1561484314-eximdsn-33613
Content-type: text/plain; charset=us-ascii
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
an undisclosed address
(generated from ORIGINAL@DESTINATION)
--1561484314-eximdsn-33613
Content-type: message/delivery-status
Reporting-MTA: dns; MX.DESTINATION
Action: failed
Final-Recipient: rfc822;INBOX@ACTUAL-DESTINATION
Status: 5.0.0
--1561484314-eximdsn-33613
Content-type: message/rfc822
// original message removed
--------------------------------------------------------------------------
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
