## Overview
The Multipart Bodypart Conversion filter is typically used to compress a MIME message before FTPing a message to an FTP server. A simple policy containing a Multipart Bodypart Conversion filter as a predecessor of an FTP Upload filter could be written to achieve this functionality.
## Configuration
The following fields must be configured on this filter screen: Name: Enter a name for this filter in the field provided. Multipart Content Type: Specify the MIME content type that you want to compress the multipart message to. To compress a multipart message to a ZIP file, enter "multipart/x-zip" in this field.
