New features in Symantec Mail Security for SMTP
Feature Description
Symantec Premium AntiSpam The premium antispam service includes the following
features:
■
Reputation service: Symantec monitors email
sources to determine how much of the email that is
sent from those sources is legitimate. Email from
those sources can then be blocked or allowed based
on the source’s reputation value as determined by
Symantec.
■
Language identification: Symantec can determine
the language in which a filtered message is written.
You can configure the premium antispam service to
automatically send messages that are written in
certain languages to a spam folder in the recipient’s
mailbox. To use this feature, you must deploy the
optional plug-in for Microsoft Outlook to the
desktop computers on your network.
■
URL filtering: Symantec builds its known-spammer
list based on URLs that appear in spam. This list
contains over 20,000 URLs.
■
Heuristic filtering: Heuristic filters scan the
headers and the body of a message to test for
characteristics that are usually inherent in spam,
such as opt-out links, specific phrases, and forged
headers.
■
Signature filtering: Messages that flow into the
Symantec Brightmail Logistics and Operations
Center (BLOC) are characterized using a unique
signature that is added to the database of known
spam. Using this signature, Symantec can group
and match seemingly random messages that
originated from a single attack.
Spam Quarantine The spam quarantine stores messages that are identified
as spam. An administrator account provides access to
quarantined messages. Users can check the quarantine
for misidentified messages, resend messages to their
inbox, and delete or search messages. Users can access
the spam quarantine through a Java-based Web server.
