Only you can tell if you have problems this might help solve. I
*guess* it can help in some cases.
Since the DNSBL queries are kind of unimportant, it might make
sense to use a separate server for those queries. You can usually
use a shorter timeout for DNSBL queries than for other queries.
I don't know if SA can be told to use a separate DNS server for
DNSBL lookups. Actually, I don't know if SA can be told what DNS
servers to use or if it simply uses the systems config.
