I am unaware of CGP providing this type of pre-queue control to helper
scripts, they are all post-queue.  Though there is a pre-queue like mode
for applying helper rules before data is fully accepted it is not the
same as something like the Postfix Access Delegation Protocol.   This
has been a big deficiency for using CGP as a filtering front-end and it
would be great if this was resolved.  Seems to be a very low priority
though.
