Managing domain and IP address groups

TRITON AP-DATA Email Gateway Help > Managing domain and IP address groups

Administrator Help | TRITON AP-DATA Email Gateway | Version 8.1.x

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 some email analysis is not performed. IP address groups can also be used for the email encryption functions.

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

You may delete a domain or IP address group from its respective list by selecting the check box to the right of the name and clicking Delete.

You should note the following 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.

Protected Domain group

The Protected Domain group should contain all the domains that an organization owns and needs the email system to protect. An open relay results when both the sender and recipient addresses are not in a protected domain.

The default Protected Domain group is empty after product installation. Domains may be added to or deleted from the Protected Domain group, but you cannot delete the Protected Domain group itself.


	Important Ensure that the Protected Domain group contains all the domains you want your email system to protect. An open relay is created when mail from an unprotected domain is sent to an unprotected domain within your organization. As a result, all mail from any domain that is not protected may be rejected.

The Protected Domain group should not be used to configure email delivery routes (in the Settings > Inbound/Outbound > Mail Routing page) if you need to define domain-based delivery routes via multiple SMTP servers. See Domain-based routes for information.

Trusted IP Address group

By default, the Trusted IP Addresses group is populated with all the IP addresses referenced in Microsoft Office 365. IP addresses may be added to or deleted from the Trusted IP Addresses group, but you cannot delete the Trusted IP Addresses group itself. The Trusted IP Addresses group may include up to 1024 addresses.

Trusted IP addresses may include your internal mail servers or a trusted partner mail server.

Mail from trusted IP addresses can bypass some relay controls (Settings > Inbound/Outbound > Relay Control).


	Note Mail from trusted IP addresses does not bypass policy and rule application.
