It goes something like this:

Say we have a CamelDataWrapper dw and a target stream target_stream. And
we want to write the data wrapper to the stream using a filter in
between:

             
CamelStreamFilter *filter_stream;
CamelMimeFilter *filter;

filter_stream = camel_stream_filter_new_with_stream (target_stream);
filter = camel_mime_filter_FILTERTYPE_new (...);
camel_stream_filter_add (filter_stream, filter);
camel_data_wrapper_decode_to_stream (dw, filter_stream);

For available filters, take a look at:
http://www.pvanhoof.be/files/libcamel-api/html/Filters.html

This is probably the most important one (decoder/encoder):

I'm not sure how I'm going to support the filtering, decoding and
encoding of data. I'm thinking about simplifying this rather than
wrapping all available filters. If others have a different opinion, let
me know.
