      You should made some network sniffing, to check if the issue is not
      other stuff like :

      - TCP ECN activated and not activated
      - fixup protocol (à la PIX and not so good)
      - Check the logs of the NIDS
      - Is the NIDS configured to RST session ? is the RST send to the
        both side ?
      - ...

      Could you show up some (tcpdump|postfix) logs with this issue ?

      Hope this helps.
