Attachment is showing as part of body when uploads from Internet Explorer 10 or 11. If same attachment is uploaded via IE 8 or IE 9 it appears as attachment in Incident snapshot.
Uploaded file to mail.naver.com via IE 8. IE 8 uploaded file using "Content-Type: multipart/form-data" method as result of this we received incident where attachment name is displayed as attachment instead of body. Where as the same upload via IE 11 uses method "Content-Type: application/x-www-form-urlencoded; charset=utf-8" which shows file name as body instead of attachment in incident.

By default DLP Network Monitor and Web prevent support multipart/form-data method for attachment. For any different method like application/x-www-form-urlencoded we need to modify NonMultipartAttachment.properties file.
