[bitfolk] Bitfolk's spamassassin service configuration

Hi all I've moved my mailserver over to my Bitfolk VPS and I've configured it to use several spam-reducing tools. I'm also using Bitfolk's shared spamassassin instance as described here: http://bitfolk.com/customer_information.html#toc_3_SpamAssassin___London__UK (many thanks for providing this, by the way!) It occurred to me that this service might be doing some of the same things as I've configured locally and that this might be unnecessary duplication. I've looked for an explanation of the configuration on the wiki but I couldn't find one. I can see from the headers on incoming spam that Bitfolk's spamds check messages against at least bl.spamcop.net, dnsbl.sorbs.net and psbl.surriel.com: X-Spam-Report: ... * 1.2 RCVD_IN_BL_SPAMCOP_NET RBL: Received via a relay in bl.spamcop.net * 0.6 RCVD_IN_SORBS_WEB RBL: SORBS: sender is an abusable web server * 2.7 RCVD_IN_PSBL RBL: Received via a relay in PSBL ... (IP addresses redacted to protect the guilty!) Andy / Bitfolk people: Would it be possible to list the external services against which your Spamassassin service is configured to check so that we can avoid double-checking them? For the record I'm adding zen.spamhaus.org to the mix as well as doing SPF and DKIM/ADSP checking (which might be duplicating DNS queries if Bitfolk's spamds are doing the same).
