Hi,

SURBL is surprisingly effective, considering the fact that it only
contains about 450-500 entries. I have written a simple command
script that downloads the rbldns zone file and converts it to a body
filter. I have scheduled it to run once a day. Here are yesterday's
stats with 9666 hits for the SURBL test (note that the individual
tests show total number of hits, while the spam summary only counts
one hit per message irrespective of the number of recipients):

Furthermore, SURBL has a rather low overlap with most other tests
(only unique hits are counted here):

If anyone is interested, I can make the SURBL script available for
download (together with some other scripts, e.g., the log analysis
and test check scripts that generated the results seen above). The
best solution is of course to have the SURBL test implemented
directly in Declude, especially since it is a realtime blocklist, but
until then this filter will do just fine.
