After watching the recent thread about filtering restrictions, it's
got me curious as to whether mine are optimal. I've recently added
support for backscatterer checking in my restrictions, and I moved
Stan's fqrdns.pcre check higher in my list per his suggestion in an
earlier thread. Mine now look like:
smtpd_recipient_restrictions =
...
check_sender_access hash:/etc/postfix/check_backscatterer,
I think your backscatterer setup may not work - the stanza below is
the only place it's used on our servers:
smtpd_data_restrictions =
...
check_sender_access btree:/etc/postfix/backscatterer,
reject_unauth_pipelining
Just as a sanity check, the contents of /etc/postfix/backscatterer:
<> reject_rbl_client ips.backscatterer.org
postmaster reject_rbl_client ips.backscatterer.org
