Hi everyone,

Tell me if this is a dumb idea: Would it be possible to have an upper 
and lower threshold on PB scoring to filter the terribly obvious spam 
from the not so obvious spam?

In single message mode, one can use the Penalty Boxes scoring system on 
a single message to mark it spam/ham. I feel it is much more powerful 
and reliable than dropping a message because of a faulty RBL hit or 
misconfigured rDNS/SPF record.

The double threshold might work like so: If your normal PB threshold is 
50, then let's say you might set the lower threshold to be 40 and the 
upper would be 65.

Messages scoring below 40 would obviously be passed on to the user with 
no problem
Messages scoring between 40-65 would be passed to the user, but with the 
[SPAM] and/or Reason tags
Messages scoring over 65 would be blocked with no further notice to the user

It would work like an extended version of the bayesian confidence 
setting, but for all tests. It would drop the most glaringly obvious 
spam (multiple rbl hits, forged helo, forged local sender, etc), but 
leave the maybe/maybe not spam (single rbl hit, single bombre hit, low 
bayesian score, etc) for the user to filter on their own via server side 
(exim) filters or client-side (outlook) filters.

Does such functionality already exist in ASSP?

One problem I already can think of is different users believing 
different things are spam/ham and wanting different thresholds. I think 
that a lot of the shortcomings in ASSP that become obvious in 
multi-user/multi-domain setups could be overcome by supporting 
per-user/per-domain configs, but that is a discussion for another thread.

Thanks,
David
