Note that end user-defined lists have precedence over all other lists. This may
affect your decision regarding whether to enable end user preferences.
Also, lists that you create have precedence over lists created by Symantec.
However, third party DNS blacklists do not have priority over all Symantec lists.
In the event of a conflict between Open Proxy Senders and an entry from a DNS
blacklist, Open Proxy Senders will “win.”
Creating groups and adding members
Group policies are configurable message management options for an unlimited
number of user groups which you define. Policies collect the spam, virus, and
content filtering verdicts and actions for a group.
Add or remove members from a group
You can specify groups of users based on email addresses, domain names, or
LDAP groups. For each group, you can specify email filtering actions for
different categories of email.
