def attachments = message.getAttachments();
attachments.values().each{ attachment ->
  def inputStream = attachment.getInputStream();
  def result = new ByteArrayOutputStream();
  def buffer = new byte[1024];
  def length;
    while ((length = inputStream.read(buffer)) != -1) {
        result.write(buffer, 0, length);
     }
  def byteArray = result.toByteArray();
   message.setProperty("attachment_body", byteArray);
}

Thank you very much. I will check it out. Also, there was already a MIME decoder as a standard feature. I will try that as well. Thank you for your time.
