Description

Currently MimeMessageInputStreamSource use DeferredFileOutputStream from commons-io which does not buffer output stream when switched to FileOutputStream. In my preliminary test, simply wrap FileOutputStream with BufferedOutputStream could make a 50% performance improvement for mail larger than deferring threshold (currently 100kb).
