unscannable

A term used to describe a message that cannot be scanned for viruses because the message exceeds either a configured maximum file size or maximum scan depth. Compound messages, such as zip files that contain many levels, may exceed the maximum scan depth.

In Symantec Brightmail Gateway, a message can be unscannable for viruses for a variety of reasons. For example, if it exceeds the maximum file size or maximum scan depth configured on the Scanning Settings page, or if it contains malformed MIME attachments, it may be unscannable. Compound messages such as zip files that contain many levels may exceed the maximum scan depth. You can configure how unscannable messages are processed.

A file that cannot be scanned by Symantec Scan Engine for any reason. For example, encrypted files are unscannable.
