take it out of master.cf, put this in main.cf:
check_sender_access pcre:$postfix/checkbs.rc
in checkbs.rc:
/^(<>$|postmaster@|MAILER-DAEMON)/ reject_rbl_client ips.backscatterer.org
this only checks bounces.
be aware, that lusers at microsoft live programmed their password
check/reset email to look like a bounce, and, ms live has been on bs.org
for some time, due to current issues.

That looks interesting, however if I put this in master.cf:
smtp inet n - n - - smtpd
-o content_filter=amavisfeed:[127.0.0.1]:10024
-o smtpd_recipient_restrictions=check_sender_access \
dbm:/etc/postfix/check_backscatterer
I get this:
postfix/smtpd[22684]: fatal: parameter "smtpd_recipient_restrictions": specify at \
least one working instance of: check_relay_domains, reject_unauth_destination, \
reject, defer or defer_if_permit
It seems I am missing something? I know this question probably belong to the \
backscatterer.org people, but as you know of it, maybe you can be of assistance.

Hi Lars,
For me it seems a bit strange to have this on the master.cf. But I have
no idea how your configuration is like.
I have it in my main.cf together with all other restriction classes.
HTH,
Mikael
