Hi, I am finding no-matter what you add into the Postfix global white/blacklist - it get's ignored: The lines: smtpd_sender_restrictions = check_sender_access mysql:/etc/postfix/mysql-virtual_sender.cf smtpd_client_restrictions = check_client_access mysql:/etc/postfix/mysql-virtual_client.cf My other config: smtpd_recipient_restrictions = reject_invalid_hostname, reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_unknown_sender_domain, reject_unknown_recipient_domain, permit_mynetworks, permit_sasl_authenticated, check_recipient_access mysql:/etc/postfix/mysql-virtual_recipient.cf reject_unauth_destination, reject_rbl_client bl.spamcop.net, reject_rbl_client sbl-xbl.spamhaus.org, reject_rbl_client cbl.abuseat.org, reject_rbl_client b.barracudacentral.org, reject_rbl_client combined.rbl.msrbl.net, reject_rbl_client cidr.bl.mcafee.com, reject_rbl_client ix.dnsbl.manitu.net, reject_rbl_client hostkarma.junkemailfilter.com=127.0.0.2, reject_rbl_client bl.spameatingmonkey.net, reject_rbl_client smtp.dnsbl.sorbs.net, reject_rbl_client web.dnsbl.sorbs.net, reject_rbl_client zombie.dnsbl.sorbs.net, reject_rbl_client cidr.bl.mcafee.com, reject_rbl_client bl.mailspike.net, reject_rbl_client spamsources.fabel.dk, reject_rbl_client bl.score.senderscore.com, reject_rbl_client new.spam.dnsbl.sorbs.net, reject_rhsbl_sender dsn.rfc-ignorant.org, check_policy_service unixrivate/tumgreyspf permit If I move check_sender_access mysql:/etc/postfix/mysql-virtual_sender.cf into the "smtpd_recipient_restrictions =" it will happily work, but surely that can't be the best solution?
