Managing domain and IP address groups

A collection of domain names or IP addresses can be defined in a single group for use in email functions. For example, you can define a domain name group to establish domain-based delivery options, or you can define an IP address group for which Reputation Service, Real-time Blacklist (RBL), or directory attack prevention analysis is not performed. IP address groups can also be used for the email encryption functions. Domain groups are added and configured on the page Settings > Users > Domain Groups; IP groups are added and configured on the page Settings > Inbound/Outbound > IP Groups.

You can perform the following operations on domain or IP address groups:

  • Adding a domain group
  • Editing a domain group
  • Adding an IP address group
  • Editing an IP address group

There are two special default groups of domain or IP addresses:

  • Protected Domain group
  • Trusted IP Address group

See Third-party encryption application for information about using the Encryption Gateway default IP address group. Default groups cannot be deleted.
