Apparently Barracuda will be publishing a free-to-use sender
blacklist called BRBL:

Haven't tried it myself but thought it may be of interest.
We have a system in use for members of a specific group within the
state. The system takes a list of ID numbers from an email and returns a
result for each number back to the sender. It requires a paid membership
and a manual verification by a human to sign up for the service. The
result emails are very structured, no images, plain text, proper and
complete headers. We have several clients who have the result emails
captured by the Barracuda Reputation System, they cannot seem to get the
result emails past their Barracuda. Other clients have no issues at all.
I have three other clients who we do spam filtering for, they have a
Barracuda between our spam filtering server and their Exchange servers.
They often trap their own intra office mail. Frank in LA emails Bob in
Atlanta, the Atlanta Barracuda says "spam" and bounces the message back
to Frank, then Frank's Barracuda says "spam" and bounces the message
back to Bob. They do not seem to be able to make it stop doing so and
will not pay for a tech to come onsite and investigate. I have a special
"slow" mail queue I dump their traffic into.
If the reputation is based on spam tagged from client managed systems I
would think it not much to count on.
