Send mailscanner RBL IP lookups to remote DNS server

[bloatedstoat]

Hello,

I'd like to send all RBL lookup queries to a remote standalone DNS server dedicated to RBL lookups only.

Our cPanel install uses the non-caching version of pDNS, a remote Bind install would go some way to getting access to our RBLs back without the "your query was blocked" issues we're currently facing.

If I were to add the following to /etc/mail/spamassassin/local.cf would MailScanner honour it and send the lookups to the dedicated DNS box?

dns_server xxx.xxx.xxx.xxx

In fact, can this be achieved at all with MailScanner?

Thank you!
