If nothing else, you should likely add a disclaimer to your rules as you
can't control the threshold at which a site may be blocked for excessive
queries.  I doubt that most users on this list have email volumes as low
as yours (100?), and will go well above the thresholds you've tested.  I
am a what I consider a small site, yet I know I would generate well in
excess of 100,000 queries in 24 hours.

So, what happens with your plugin should a timeout or ban occur?
