Filters
The premium antispam service supports the following types of
filters:
■
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.
