Everyone who uses e-mail needs spam filtering, and some filters definitely work better than others. Some people we know were trying to design tests of filter quality, which turns out to be extremely difficult.

What one might call 'filtering quality' assessment, should be the very very last step after "does it have the features I want?", "does it install/is it supported/supportable?", "does it crash?", "does it make lots of stupid mistakes?", "is it likely going to compare favorably with what we already have?".
