there are a number of these servers, if you look at the url that I gave you.  One that should be pretty effective is one that concentrates on Asian spammers.  Apparently tons of spam is coming from Korea, China and Taiwan.  We do lots of business with Asia so we can't use that.  However, if we could, I bet that it would get rid of lots of the really filthy stuff that seems to hit us.

I agree, ordb seems a little passive for our taste.  Spamcop seems to be one of the most aggressive.  In spam, aggressive is good.  We have also noted that osirusoft and spamcop seem to be a good complement.  Stuff that gets by one usually gets caught by the other.

John,

I set this up last night as was very impressed; only had "relays.ordb.org" and was getting nil filtering -- a fraction of what my subject and body filters were getting.

Using all three, the rbl_filter trapped 75-80% of what my "aggressive" subject and body filters are getting.

If rbl filtering gets this good, my not need subject or body filters :)

I have mine copyto (I have a special account for this:
dynhost@xxxxxxxxxxxx) and discard too just to monitor.  However, they
seem to be pretty accurate for our needs.
