I have problems with ispconfig postfix whitelist. I add a domain who was listed in RBL barracuda and posfix continues blocking: Log: Code: Nov 7 09:16:18 mail postfix/smtpd[3979]: NOQUEUE: reject: RCPT from unknown[213.139.1.119]: 554 5.7.1 Service unavailable; Client host [213.139.1.119] blocked using b.barracudacentral.org; Client host blocked using Barracuda Reputation, see http://www.barracudanetworks.com/reputation/?r=1&ip=213.139.1.119; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<bosco.netma.com> I have Ubuntu 16.04.1 Ispconfig 3.1.1p1 postfix 3.1.0 main.cf: Code: smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, check_recipient_access mysql:/etc/postfix/mysql-virtual_recipient.cf, reject_rbl_client zen.spamhaus.org, reject_rbl_client b.barracudacentral.org, reject_rbl_client cbl.abuseat.org, reject_rbl_client bad.psky.me, check_recipient_access mysql:/etc/postfix/mysql-virtual_policy_greylist.cf Code: smtpd_sender_restrictions = check_sender_access regexp:/etc/postfix/tag_as_originating.re , permit_mynetworks, permit_sasl_authenticated, check_sender_access mysql:/etc/postfix/mysql-virtual_sender.cf, check_sender_access regexp:/etc/postfix/tag_as_foreign.re Code: smtpd_client_restrictions = check_client_access mysql:/etc/postfix/mysql-virtual_client.cf What can i do?
