An address group is a list of email addresses to which your policy applies. Address groups allow you to organize multiple email addresses into a single group and apply the same policy to every address in the group.

For example, you have identified three types of content that you do not want transmitted through your company’s email system and have defined three filters (in parentheses) to detect these types of content:

Consider the following address groups within your company:

The filters that you use in the policies will be applied to these groups as follows:

Executives, HR staff, and IT developers have legitimate business reasons to send financial information, job search-related correspondence and VBS files, respectively, so you would not apply some filters to those groups.

In IMSS, email addresses identify the different members of your organization and determine the policies that apply to them. Defining accurate and complete address groups ensures that the appropriate policies apply to the individuals in those groups.
