I'm not learning anything new from this thread, I don't know if anyone
else has. I've been looking at getting an anti-spam tool for a while now
and evaluations have told me one thing - there isn't a tool that works
all of the time and makes everyone happy.

There are disadvantages to all of the tools. The one big advantage to a
challenge response tool? People stop complaining that they're getting
spam. Every other tool lets some spam through unless you completely lock
it down and then you miss legit email. This one in it's default setting
stops spam from getting to the end user.

As with everything, you have to train your users to use it properly or
the tool is completely useless.

We still haven't made a decision, and the spam goes on...
