Custom file types

The cloud service provides a number of file formats and file types to enable you to manage messages containing attachments. File types allow you to quarantine attachments by specific formats, for example GIF files or HTML documents. File formats are more generic: for example, the Sound format includes anything related to sound files, including RealAudio, Windows Media Audio, MPEG Audio, and MIDI files.

If the available file formats and types do not meet your requirements, you can set up custom file types containing one or more file types and MIME types. You can then use the custom file types to quarantine or park messages with the attachments you specify.
