public int filter_add (MimeFilter mf)
Add a filter that will be applied to any body content before it is passed to the caller.
Filters may be pipelined to perform multi-pass operations on the content, and are applied in the order they were added.
Note that filters are only applied to the body content of messages, and once a filter has been set, all content returned by a step with a state of CAMEL_MIME_PARSER_STATE_BODY will have passed through the filter.
