    When using the resolvers from your ISP some RBL stop working because of free usage limits.
    E.g. DnsBlocklists - Spamassassin Wiki

    If a set with separate cpanel dnsonly is available is there a best practise to also use them as resolvers.

    And is there a proven way to separate the way resolvers are used.

    You can modify the resolvers used on your system by editing the following file:

    /etc/resolv.conf

    You may find the following thread helpful:

    Setup Own DNS Resolvers on DNS-Only

    Thank you.

    Thanks Micheal, I already had read this thread you posted. I am looking for specific ideas to tackle the rbl query limit. Not sure if own resolvers for different servers in different datacenters are the way to go. Since a few others should have run into this limit with spamassassin I hope to get some insight. Let's see.
