I did that myself for quite some time, but note that while this of
course reduces the number of false negatives, it also increases the
number of false positives, so you won't necessarily increase the global
accuracy with such a setup. Giving useful _measures_ is really hard
though as they will heavily depend on the configuration/training of the
filters and of course also on the actual mail corpus they operate on.
