[Exim] ACL reverse_host_lookup

Hi,

is the following possible?


=========================================
hostlist broken_mxs = 213.164.69.229 : 168.215.198.88

acl_check_rcpt:
  require  verify        = reverse_host_lookup
           hosts         = ! broken_mxs
           message  = reverse host lookup failed
=========================================

In special I have a problem with the ACL not regarding the hosts which
should NOT be checked.
It looks like exim pays no attention to the hosts entry...
So my question is if this ACL statement should work...
