I have been doing the following.
In the main.cf, note the spamsources:
smtpd_client_restrictions =
permit_sasl_authenticated,
permit_mynetworks,
reject_unauth_destination,
check_reverse_client_hostname_access pcre:/etc/postfix/fqrdns.pcre,
reject_unknown_reverse_client_hostname,
check_client_access hash:/etc/postfix/spamsources
smtpd_sender_restrictions =
permit_sasl_authenticated,
permit_mynetworks,
reject_unauth_destination,
reject_unknown_address,
check_sender_access hash:/etc/postfix/spamsources
I have a file called spamsources. The basis pattern is a tld, 500, and
a friendly message:
------
stream 500 your message
download 500 your message
top 500 your message
xyz 500 your message
-----------
You need to postmap the file to make spamsources.db
These goofy tlds are cheap to buy, hence a spam source.
