Forum OpenACS Development: Getting rid of "crud" and prior responses in incoming email

I remember we used to do some processing to the incoming emails to remove various types of crud that would appear when people respond to the forum. For example, if they responded and the previous reply was attached.

There is no such processing in there now. Anyone know where this code is?

Also, by the time the forum code gets the incoming message, it is already switching into text instead of HTML. Anyone know where this happens?
