Some comments about SURBLs
- Catherine Hampton, spambouncer.org:
- "The results have been nothing short of amazing; the only
blocklists that come even close [to SURBLs] in terms of
quantities of spam stopped are the SBL and CBL.
Given that you don't even need to look up host IPs to check the
SURBL, it has to qualify as one of the most useful BLs I've ever
tried."
- Ben Poliakoff, Reed College:
- "SURBL use has enhanced SpamAssassin's accuracy tremendously."
- Bob Harbour, President, Harbour Communication:
- "The improvements in the last 2 weeks has been amazing with the
addition of the SURBLs and the SpamAssassin 3. I am beginning to
get calls from customers wondering if we are having problems with
our mail server because they are not getting as much junk mail as
they were."
- Matt Yackley, Network Engineer, Perkins + Will, Inc.:
- "SURBL is one of the best tools available to help SpamAssassin catch
more spam than ever before."
- Lindsay Snider, Cumberland Technologies Inc.:
- "SURBL has been excellent for us. Before SURBL, we
continued to add and update SpamAssassin rules to try and catch spam as it
changed over time. Eventually, we began to see our
false positive level gradually increase, hence lowering our trust in the
system. We went back to basics using a stock SpamAssassin with the safe
SARE rules. We then turned up SURBL and ever since then
our scores have been a good deal more accurate.
Our false positive rate is zero or very near,
and very little spam gets through untagged anymore."
- Ross Carlson, Metacraft Internet Services:
- "I upgraded to the latest amavisd-new and SA, enabled the
DNSBL checks and now the system is tagging about 40% of the incoming
mail as spam, compared to about 5% before. I've had nearly 4,000
messages come through in the last 22 hours that had URIs in the SURBL.
Love it!"
