[exim] message / log_message from sub ACLs

Hi,

Given a "subroutine" ACL like:

acl_check_spam:
   deny
     dnslists = <whatever>
     message = <something>
     log_message = <something>

   deny
     <more anti-spam measures...>

accept

called from a "warn" statement like:

acl_check_rcpt:
   warn
     !acl = acl_check_spam

then is there any way to get at the "message" or the "log_message" setup
by whichever acl_check_spam statement denied ?

( the log_message doesn't get logged in this scenario, as far as we can see )

Thanks for any clues!
