Overview of Mail Policies
The Email Security appliance enforces your organization’s policies for messages sent to and from your users through the use of mail policies. These are sets of rules that specify the types of suspect, sensitive, or malicious content that your organization may not want entering or leaving your network. This content may include:
- legitimate marketing messages
- phishing and other targeted mail attacks
- confidential corporate data
- personally identifiable information
You can create multiple policies that satisfy the disparate security needs of the different user groups within your organization. The Email Security appliance uses the rules defined in these policies to scan each message and, if necessary, perform an action to protect your user. For example, policies can prevent the delivery of suspected spam messages to executives while allowing their delivery to IT staff but with a modified subject to warn them of the content, or drop dangerous executable attachments for all users except those in the System Administrator group.
