I’ve added following lines to my main.cf of Postfix to try to block more spams.

strict_rfc821_envelopes = yes
parent_domain_matches_subdomains = smtpd_access_maps
smtpd_helo_required = yes
smtpd_sasl_auth_enable = yes
smtpd_recipient_restrictions =
 permit_mynetworks,
 permit_sasl_authenticated,
 reject_unauth_destination,
 reject_invalid_hostname,
 check_client_access hash:/usr/local/etc/postfix/access_client,
 reject_unauth_pipelining,
 reject_non_fqdn_sender,
 reject_unknown_sender_domain,
 reject_non_fqdn_recipient,
 reject_unknown_recipient_domain,
 reject_rbl_client sbl.spamhaus.org,
 reject_rbl_client blackholes.mail-abuse.org

Also ADSL with dynamic IPs from Taiwan listed in access_client are blocked.
