Feature Cross-Reference 207 About email filtering and message handling options ■ Content compliance policies ■ Email Firewall Policies: Like settings, these policies affect all users. However, they enable you to create specific system-wide strategies for handling email, including: ■ Attacks: Create strategies for automatic response to directory harvest attacks, spam attacks, and virus attacks. ■ Sender Authentication: Authenticate senders using either the Sender Policy Framework (SPF), or Sender ID, or both. ■ Sender Groups: Manage three types of Allowed Sender Lists, specify actions for three types of Blocked Senders Lists, and enable or disable three Symantec-managed Reputation Service lists. ■ Policy Resources: Create sets of data that enable further customization of email filtering and the actions taken on filtered email. You can employ policy resources when you create filter policies. Policy resources include: ■ Annotations (called Custom Disclaimers in Version 4.1): Add custom text to the beginning or end of the message body. ■ Archive: Send messages to a specific email address for storage. ■ Attachment Lists: Specify lists of attachment types for use in filtering, based on file naming or on the true type of each file, or use any of five pre-filled lists. ■ Dictionaries: Specify sets of words for use in filtering, or use of several predefined dictionaries. ■ Notifications: Create messages that can be sent to specific parties when filtering finds specific kinds of messages. ■ Group Policies: Tie all of the above categories together by specifying which filter policies apply to each group of users. You can specify groups of users based on email addresses, domains, LDAP groups, or IP addresses. Group Policies specify filter policies. Filter policies can make use of policy resources. Email firewall policies and email scanning settings can affect all messages.
