    maybe taking a OutputStreamSupplier as a parameter would allow to decouple the concerns
?

> 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).
