Whether it defeats the purpose depends on what the purpose is.
Is it a tool to save the bandwidth of accepting spam in the
first place?  Or is it a source of information for the process
of classifying messages as spam/ham?  It's whichever you want
it to be.

And what you want depends on the cost of receiving and
scanning messages and whether you're willing to pay that cost.
And that, in turn, depends on the resources (server hardware
and bandwidth) available have versus the consequences of knowing
that you've discarded/refused when you've had false positives.
