Safe Senders
A list of IP addresses from which no outgoing email is spam, provided by Symantec based
on data from the Probe Network. Part of the Sender Reputation Service, Safe Senders is a
sender group in Symantec Mail Security for SMTP. You can specify actions to take on
messages from each sender group.

one or many Scanners. The configuration of each Scanner is managed via the Control
Center.
security The policies, practices, and procedures that are applied to information systems to ensure
that the data and information that is held within or communicated along those systems is
not vulnerable to inappropriate or unauthorized use, access, or modification and that the
networks that are used to store, process, or transmit information are kept operational and
secure against unauthorized access. As the Internet becomes a more fundamental part of
doing business, computer and information security are assuming more importance in
corporate planning and policy.
sender group A category of email senders that Symantec Mail Security for SMTP manages using the
Email Firewall feature. Sender groups can be based upon IP addresses, domains, third
party lists, or Symantec lists. You can configure the Email Firewall to take a variety of

Symantec Mail Security for SMTP allows you to specify an action for messages that fail
Sender ID authentication.

Symantec’s other filters.
