When using the resolvers from your ISP some RBL stop working because of free usage limits. E.g. [url=http://wiki.apache.org/spamassassin/DnsBlocklists#dnsbl-block]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.
