This one has been working well for me:

sbl.spamhaus.org

I wrote a little php script that parses the mail log to tell me which DNSBL
is blocking the most spam so I could play with different DNSBL's and their
order.  After hundreds of thousands of SMTP connections, here are the
DNSBL's that are most effective for me and the order I use them in:

DNSBL NAME                              % of Spam mail blocked
----------------------------------------------------
sbl.spamhaus.org                                58%
blackholes.easynet.nl                   26.5%
bl.spamcop.net                          15.5%

This configuration is blocking 97% of all mail coming into my server.  (Do I
have a spam problem or what?) I played with every possible DNSBL order and
this order worked the best for me.  I don't know anything about spamhaus;
like whether or not they are dependable or if they are too aggressive about
blocking servers that shouldn't be blocked, etc.  I am simply publishing the
results that worked the best for me as far as blocking the most incoming
e-mail.  I can say that I haven't had any complaints about blocked e-mail
other than 3 newsletters that appear to not be related to DNSBL's at all.
(I service about 75 e-mail accounts).

I dropped proxies.blackholes.easynet.nl and spam.dnsrbl.net because they
were blocking less than 5% of the spam so I felt the extra bandwidth needed
to do the query wasn't justified.  If  either of these DNSBL's were listed
first, they still only blocked about 20% of the spam.  According to my
tests, using spamhaus alone will block over 75% of all spam.

Since you told me the news about easynet.nl, I'm doing a test using just
spamhaus and spamcop in that order.  I'll publish the results when it
handles a few thousand emails so the results will be statistically
significant.
