    I want to know which email spammers "Black Hole Lists" do you fill in the ISPConfig 3.1 control panel form?

    By default, there is only the Is it enough? :rolleyes:

    My experience is it does not work if you enter them in the ISPConfig form.
    I edit /etc/postfix/ I have now
    grep recipient_restrictions
    smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, reject_rbl_client, reject_rbl_client, reject_rbl_client, check_recipient_access mysql:/etc/postfix/, check_recipient_access mysql:/etc/postfix/

    There are very few rbls which are good enough to reject with, you get lot more benefit from using postscreen with weighted rbls, as you can use many lesser quality rbls which couldn't be used alone to add up and reject based on multiple hits.
    concept21 and Taleman like this.
