Statisticlly using DSPAM and then using SA with its results will make it
alot worse that just using DSPAM
SA gets ~95% correct, but DSPAM can get more like 99.995% correct after a
while.. Heurestuc Spam systems such as SA (yes HA bas bayesium stuff, but
its crap in its accuracy)) need constant updateing with new rules.
Stastistic systems such as DSPAM/Death2Spam etc just work.
I've love to see anything that will do better than DSPAM on the market (Free
or Commercial)
Any Anti-Spam people companies out there on this list want to compare it
with DSPAM?
Thanks

Yes, SA is one of my SMTP time filters as part of an Exim ACL. It is set
to
high enough to not have false positives, but blocks about 60% of the SPAM
which make it that far (I have other simple rule filters before SA; such
as
Distributed Check Sum). And just a note: I do not use the result of my
other
filters to train DSPAM. That tends to cause problems. As for the
percentage,
yes DSPAM can do that, although I do not know how.

There is no reason to place the result into SA. SA has its own bayes

check before acceptance) during the SMTP session without the bayes filter;
just rule based.

That's interesting. So SA is a prefilter to DSPAM? Do you reject email
at SMTP time with SA and then use DSPAM on what's left?
Spamprobe has a way of returning a one line score. I can:
cat message| spamprobe score
And I get a result with a number line 0.988234 so I can then process
that number. Can DSPAM do that? I'm also having problems compiling it
under Fedora Core 4 - can't find libmysqlclient - but I should go to
their support forum to solve that.
