Another approach is to impose a delay penalty on HTML, with the argument 
that it takes much more resources and it's much more error prone to 
determine if HTML is legitimate and not spam. Run all HTML through a 20 
minute queue, but pass plain text instantly.

Or maybe run separate filter processes for HTML, niced down a lot. On a 
heavily-loaded server, plain text goes to the front of the line.
