At this step, create a list of trusted networks and network hosts that are allowed to send email messages via Kaspersky Secure Mail Gateway.
As a rule, these are internal networks and network hosts of your organization.
For example, you can specify the IP addresses of Microsoft Exchange servers used at your organization.
If trusted networks are not specified, Kaspersky Secure Mail Gateway will not be receiving messages from internal mail servers and redirect them outside the network of your organization.
To add a list of trusted networks and network hosts:
Type the domain names in FQDN format.
Type IP addresses in IPv4 format or subnet addresses in CIDR format.
The Adding a trusted network window closes.
Addresses are added one at a time. Repeat the process of adding addresses to the list for all addresses that you are adding.
Proceed to the next step of the wizard.
