Probably to avoid confusion on the user's part.  As long as you
understand each DNSBL's listing reasons, there's no real reason not to
use several.  Speed of DNS lookups could slow mail delivery.  Put the
larger, aggregate lists like sbl-xbl.spamhaus.org and list.dsbl.org
first to get the most from each lookup.

Yes, the sbl-xbl lists are excellent.  Conservative but effective.

Installing the clamav-milter in addition to DNSBLs helps tremendously.
The daily barrage of Windows viruses just disappears.
