I think an MTA level configuration for using some block lists can help you.

Like this, for our postfix+postgrey mailservers:


smtpd_sender_restrictions =
        check_sender_access hash:/etc/postfix/sender_access_rejected,
        hash:/etc/postfix/access,
        permit_mynetworks,
        reject_invalid_hostname,
        reject_non_fqdn_sender,
        reject_non_fqdn_recipient,
        reject_non_fqdn_hostname,
        reject_invalid_hostname,
        reject_unknown_sender_domain,
        reject_unknown_recipient_domain,
        reject_unauth_pipelining,
        reject_unauth_destination,
        check_recipient_maps,
        reject_rbl_client relays.ordb.org,
        reject_rbl_client list.dsbl.org,
        reject_rbl_client sbl-xbl.spamhaus.org,
        reject_rbl_client combined.njabl.org,
        reject_rbl_client bl.spamcop.net,
        reject_rbl_client dnsbl.sorbs.net,
        check_policy_service inet:127.0.0.1:10030,
        permit_mx_backup
