[Exim] Problems with ${lc:$domain}

Hi Folks,

whats wrong with this condition :

require_files = \ /opt/virtual-lists/${lc:$domain}/lists/${lc:$local_part}/config.db

exim 4.10 failed with :

Sep 4 23:04:14 lara exim[11218]: 2002-09-04 23:04:14 H=a087016.adsl.hansenet.de
(gandalf) [213.191.87.16]:34590 sender verify defer for <tks@???>: failed
to expand "/opt/virtual-lists/${lc" for require_files: "${lc" is not a known
operator (or a } is missing in a variable reference)


Hope for some good ideas...

Kind Regards
Christian
