a) Use or build a Milter proxy that sits between Postfix and Milter
and replace the SMFIR_DISCARD reply code 'd' with SMFIR_REJECT code
'r'.
b) Modify the Milter with a binary editor and replace SMFIR_DISCARD
reply code 'd' with SMFIR_REJECT code 'r'. Have some fun.
c) Modify Postfix. May the source be with you.
