Comment 2 for bug 1998678

Thanks Andreas; from the upstream discussion sounds like there is an issue with early expansion of internally bracketized elements, e.g. "${quote:1}". The upstream patch looks sensible and probably not terribly difficult to backport.

Thomas, can you attach (not paste) your exim4 configuration files to this bug report (please remove any passwords, host/network names, or other private info that may be in there).
