A feature of Symantec Mail Security for SMTP that provides automated synchronization
between LDAP directory sources and Symantec Mail Security for SMTP. This feature
enables alias expansion, facilitates application of filtering policies to users and groups,
and provides enhanced performance.
TCP (Transmission
Control Protocol)
The protocol in the suite of protocols known as TCP/IP that is responsible for breaking
down messages into packets for transmission over a TCP/IP network such as the Internet.
Upon arrival at the recipient computer, TCP is responsible for recombining the packets in
the same order in which they were originally sent and for ensuring that no data from the
message has been misplaced in the process of transmission.
TCP/IP (Transmission
Control Protocol/
Internet Protocol)
The suite of protocols that allows different computer platforms using different operating
systems (such as Windows, MacOS, or UNIX) or different software applications to
communicate. Although TCP and IP are two distinct protocols, each of which serves a
specific communications purpose, the term TCP/IP is used to refer to a set of protocols,
including Hypertext Transfer Protocol (HTTP), File Transfer Protocol (FTP), Simple Mail
Transfer Protocol (SMTP), Post Office Protocol (POP), and many others. This set of
protocols allows computers on the Internet to exchange different types of information
using different applications.
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.
toolbar
The various rows below the menu bar containing buttons for a commonly used subset of
the commands that are available in the menus.
Transformation Engine
A component of a Symantec Mail Security for SMTP Scanner that performs actions on
messages.
true file type
recognition
A technology that identifies the actual type of a file, whether or not the file extension
matches that type. In Symantec Mail Security for SMTP, 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 for SMTP, 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.
