A novel idea, perhaps, but it's been pretty much done already.

The only problem with the approach is that it still allows the spam to use up
bandwidth, CPU and storage on your network/hosts, and does nothing to modify
the behavior of irresponsible companies or ISPs.  In other words, it doesn't
really have any consequences for the spammers.

IP-based blocklists (run at the MTA level) are a better solution in this
regard.

Of course, if you don't have control over your MTA, then I do recommend TMDA as
an excellent way to at least keep you from seeing what got on your network.
