DSPAM can give results of 99.995 accuracy. (I've had that at times), but the
best I've seen with SA is 95% correct.
We use DSPAM on a large number of customers, and as its not Heurestic, there
s no need to update anything (like you have to do with SA).
Training/retraining can be make to do it automaticly for customers (via
forwarding or via webmail etc)
Its just as good (or better) than other commercial software.
Thanks

Me.
I switched ca. 9 months ago when SpamAssassin failed to detect more and
more spam (had around 5-10 false negatives in a week with ca. 3500
mails/week). DSPAM is far better (2-3 false negatives) and produces less
false positives especially for unknown senders/uncommon subjects. DSPAM
classified messages as ham which I would have deleted without further
notice because they look so spammy but in reality they WERE ham.
DSPAM needed quite a big training corpus for me (10000 ham/spam mails)
and you should test it thoroughly as it rewrites mails (signature in the
body) and imho these routines could be implemented more
conservatively/carefully. For example in 3.4 it destroyed subjects with
umlauts and S/MIME signed messages. While the first bug was fixed in 3.4,
S/MIME signed message were not (at least until 3.4.7, don't know newer
versions).

Can it be made to not modify the message at all or to just add one header
line with a score? I just want to use it to get a second opinion and then
process the scroe with Spamassassin.
