Symantec Spam Folder
Agent for Exchange
An application designed to work on Microsoft Exchange Servers. Installed
separately, the Symantec Spam Folder Agent for Exchange creates a subfolder
and a server-side filter in each user's mailbox. The filter gets applied to messages
that a Scanner identifies as spam, routing spam into each user's spam folder,
relieving end users and administrators of the burden of using their mail clients
to create filters.
synchronize
To copy files between two folders on host and remote computers to make the
folders identical to one another. Copying occurs in both directions. If there are
two files with the same name, the file with the most current date and time is
copied. Files are never deleted during the synchronization process.
SyncService
A feature of Symantec Mail Security that provides automated synchronization
between LDAP directory sources and Symantec Mail Security. This feature enables
alias expansion, facilitates application of filtering policies to users and groups,
and provides enhanced performance.
threat
A circumstance, event, or person with the potential to cause harm to a system in
the form of destruction, disclosure, modification of data, or denial of service.
TLS (Transport Layer
Security)
A protocol that provides communications privacy over the Internet by using
symmetric cryptography with connection-specific keys and message integrity
checks. TLS provides some improvements over SSL in security, reliability,
interoperability, and extensibility. See also SSL.

extension matches that type. In Symantec Mail Security, you can specify filtering
actions based on the true file type or true file class of a file, or you can filter based
on the file name or extension.
unscannable
In Symantec Mail Security, 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.
virus
A piece of programming code inserted into other programming to cause some
unexpected and, for the victim, usually undesirable event. Viruses can be
transmitted by downloading programming from other sites or present on a diskette.
The source of the file you are downloading or of a diskette you have received is
often unaware of the virus. The virus lies dormant until circumstances cause the
