For what it's worth, I use MailScanner with no RBLs at the MS level, only in SA.
I run a local DNS server, and I periodically see this in netstat -anp:

udp     8736      0 127.0.0.1:33867         127.0.0.1:53            ESTABLISHED
18169/MailScanner:


which is the MailScanner process connecting to the local DNS server, presumably
for SA RBL lookups.
