    I added additional spam checks to my postfix in main.cf
    smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_invalid_hostname, reject_non_fqdn_hostname, reject_unknown_recipient_domain, reject_non_fqdn_recipient, reject_unauth_destination, reject_non_fqdn_sender, reject_unknown_sender_domain, reject_unknown_recipient_domain, reject_rbl_client cbl.abuseat.org,reject_rbl_client dul.dnsbl.sorbs.net,reject_rbl_client ix.dnsbl.manitu.net, check_recipient_access mysql:/etc/postfix/mysql-virtual_recipient.cf, reject_unauth_destination
    The checks are quite powerful and are eliminating most of the spam mails. Now, I'm facing an issue with facebookmail.com. Some of the facebook notifications are blocked by ix.dnsbl.manitu.net.
    I added facebookmail into the postfix whitelist filter but the mails are still being blocked.

    Is there a way to check the postfix white- and blacklist filter before the dnsbl checks?

    Thanks a lot for your help!
