I think your description is correct. When I checked it out a while ago I
got the impression Razor and Pyzor were the same idea written in
different languages and that they do query the same database which makes
it useless to have both, just bump the score on one would have the same
effect with less network traffic.
Since SA is the slowest thing on a MailScanner box I looked for
efficient use of the network and DCC got my vote, it uses a single UDP
packet for the query and another for the answer. They also update the
software more often than the others and Paul Vixie is behind it which in
my book makes it good.
I think that since they all share the same idea you shouldn't use more
than one, just bump the score instead. At least in theory they should
give the same result most of the time. You wouldn't query the same RBL
twice, would you? You would double the score instead if you trusted it.
Less things to break and upgrade. Less network traffic which means
better performance.
DCC has been very reliable for me and it's always in the top 5 of my
spam traps. Top 3 of the ones with more points (Bayes99, SpamCop and
DCC). I would much rather bump the score than add another very similar
product.
