Greetings,

It could be done.

As bogofilter processes multi-part mime it could keep the token lists 
separated for the different parts.  Given both text/html and text/plain, it 
would be possible to use the tokens from one and discard the tokens from 
the other.

As a research project, someone could make the changes and test to see how 
much difference the changes make.

Ciao,

David
