RE: [cobalt-developers] Adding spam blacklists to sendmail on a Cobalt server

["ISPGuru" <bobgerman@xxxxxxxxxxx>]

I'm using ORDB, Spamhaus, NJABL, and the monkeys open proxy list with
plenty of success.  Across fourteen servers we are blocking a total of
70,000 to 80,000 messages per day.  We definitely saw false positives
right away with Spamcop when we implemented it, and since other people
on the net (see Google) have reported similar results, we figured better
safe than sorry.  The key is, use whatever lists you want -- then when
spam gets through, run it through Spamcop's web reporting tool, and it
will tell you if that spam source was on any lists that it knows about.
If it was, consider using that list.  If it wasn't, there wasn't much
you could do about it anyway.  Report it and move on.

Can you please give us some examples of good RBLs to use that will give
us the same coverage as spamcop without being what you call "too
aggressive"?  I ask because we use spamhaus, spamcop and ordb, and we
find that spamcopy catches over twice as much as the others put
together.  We've only had two false positives show up with spamcop in
about a year.

I agree, but the others can have this problem as well.  In our real-life
example, we've never had the problem.

They all say that, or certainly should, to avoid any responsibility.

So, which ones <smile>?
