GitHub user chikei opened a pull request:

    JAMES-2343 Use buffered file output stream for MimeMessageInputStreamSource

    Couldn't figure a way to reuse existing DeferredFileOutputStream, so I just copy it and
add buffer.

> 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).
