I added additional spam checks to my postfix in main.cf Code: 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! Chris
You can not exclude domains from the rbl-check but you can whiteliste some ips from the rbl-check (or just remove ix.dnsbl.manitu.net). https://www.howtoforge.com/how-to-whitelist-hosts-ip-addresses-in-postfix
