It looks like to rewite that filter example code id have to use 
filter_message() and extract the same info from $ctx->mime_entity.

The part that isn't clear to me is does filter_message() run once for 
the entire email and all the mime parts are inside the one 
$ctx->mime_entity?

Or does filter_message() run multiple times once for each part like 
text/plain, text/html, application/pdf, etc?
