ePrism User Guide - EdgeWave

Policy Overview
customize each configuration item individually. For each individual user group or domain, you can
use the Default Policy, or customize each group or domain individually.
Multiple Group Membership
In the event users are members of multiple groups, and different policies apply for these groups,
the following rules apply. In general, the least restrictive policy is applied when multiple group
membership policies apply.
Note: If a recipient or sender belongs to a group that does not have a policy defined, then
the Default Policy is used. In the situation where multiple policies are in effect, the least
restrictive policy will apply. If the Default Policy is the least restrictive, it will be the policy
in effect. It is a recommended best practice to make the Default Policy more restrictive
than the individual group policies.
Attachment Control
If a user is a member of more than one group when using attachment control, a setting of PASS
for any of the group policies will result in the attachment being passed though.
• Group A: Attachment Control is set to PASS
• Group B: Attachment Control is set to BLOCK
Result: The attachment will PASS.
Anti-Virus
• Group A: Anti-Virus ON
• Group B: Anti-Virus OFF
Result: The messages for the user will not be scanned for viruses.
Anti-Spam Scenario 1
• Group A: STA/DCC ON
• Group B: STA/DCC ON
Result: The message will always be flagged with an STA metric or DCC value for the mail
transport logs, and the specified action (such as Modify Subject Header) will take place.
