Could not the same procmail rule used for detecting mail duplicates be
using at the mail entry ? Something like :

:0 ic
| cd procmail/mail.backup && rm -f dummy `ls -t msg.* | sed -e 1,1024d`

# don't guard duplicated mails.
:0 Whc: procmail/msgid.lock
| formail -D 8192 procmail/msgid.cache
# let's save them to procmail/duplicates for now.
:0 a:
procmail/duplicates

Maybe a bit adapted for the particular kind of bounces ?

Or you could add a special tag to the headers, and reject bounced mails
which present this header or something ?
