I get relatively little.
I'm using Exim4 + some RBL checks + some custom checks + ClamAV +
SpamAssassin (using some of the SARE rulesets, an OCR plugin for image
spam, and Bayes tests).
During the last four weeks, ratio of reject:accept as follows:
exim_main.log.4 10428 : 730
exim_main.log.3 9967 : 703
exim_main.log.2 11870 : 915
exim_main.log.1 14411 : 686
exim_main.log 9883 : 662
So... between 93 and 96% of all connections fired at my main MX result
in rejections of some sort. And I don't get people shouting about false
positives either, apart from once in a blue moon a Yahoo group my wife
subscribes to shuts her out because their messages get rejected (most
often because they contain multiply-forwarded messages). There is a
method for complaints which slips the checks so that people being
rejected know where to complain to :)
...and to followup to Chris Burton's email where he listed:
cbl.abuseat.org is included in sbl-xbl.spamhaus.org, which is the one I
use (personal preference).
IMO bl.spamcop.net should never be used, but that's because I've been on
"the receiving end" as a hosting administrator. The Spamcop listing
policies are too easy to subvert (given that they're automatic),
although getting off bl.spamcop.net is as easy as getting on it. I have
no comments about list.dsbl.org as I've never used it.
