That might work a tad better, yep.  The Return-path: rule is header-only
as is the local sent Received: rule, but the others are body-only.

Justin's idea to use the IP address works too, but I did get a few false
positives for that exemption.

  - I searched my ham and bounces for these Return-paths:
    - <>
    - <mailer.?daemon
    - <postmaster
    - <.*(virus|norton|amavis|symantec).*\@
  - producing 787 messages for which looked for the following exemptions:
    - locally received in header ("local")
    - my From: header in body ("from")
    - my Message-Id: in body ("msgid")
    - my IP in body ("ip")

count           exemptions              verdict
638             none                    almost definitely blowback
51              ip from                 real bounces
24              local msgid             real bounces
17              ip msgid                real bounces
15              from local              real bounces
12              local                   real bounces
9               ip from local           real bounces
4               ip local msgid          real bounces
4               ip from msgid           real bounces
4               ip                      2 real bounces, 2 blowback
3               ip from local msgid     real bounces
3               from local msgid        real bounces
2               from                    real bounces
1               msgid                   1 blowback

count per each exemption:
  ip      92
  from    87
  msgid   56
  local   70

Hmmm... I accidentally added my MTA message-id format as an exemption,
producing that one "false positive" for msgid at the bottom.
