  A QUICK block is to add following line to   smtp-policy.spam.manual:
	"relaytest@abuse.net"@
  then it won't be received at all, but that isn't generic stopper.

  Does the message go thru ?  It should not, but I am not quite sure
  what it did back at 2.99.51..

  Even my current source accepts that, however it stops inside.
  Central to that stopping is folloing:

-       address="$(dequote "$address")"
+       # address="$(dequote "$address")"
 #
 # We need string ssift to detect '|' because '|' is not RFC822 special
 #


  However it alone breaks a few other things.  Quoted strings
  are then not valid as local parts at all -- fix is to add explicite
  dequotes in a few places, but perhaps easier would be to pick
  2.99.52+patch1  (router and router scripts)
