Domains and configuration of email routing

This section contains information on how to add domains and email addresses to a transport map, configure email routing for those domains, remove domains from the list, configure TLS security modes for incoming and outgoing email messages, and add a DKIM signature to messages.

By default, Kaspersky Secure Mail Gateway uses the settings of your DNS server for email routing. You can manually configure email routing. To do so, you must create a transport map. In the transport map, enter the names of the domains for which the email messages are intended and then enter the IP addresses or fully qualified domain names (FQDN) to which Kaspersky Secure Mail Gateway will be redirecting messages intended for these domains.

Example: If you want messages that are intended for the domain example.com to be redirected to the address 1.1.1.0:25, you must perform the following actions: Add the domain example.com to the transport map. Specify the IP address 1.1.1.0 and port number 25 for routing messages intended for the domain example.com.

This section also describes configuration of email routing for local domains (relay_domains).

Local domains (relay_domains) are domains of your organization for which Kaspersky Secure Mail Gateway will be receiving email messages from the outside. Kaspersky Secure Mail Gateway will receive messages only for the domains you specified. Messages intended for other domains are rejected.

If local domains are not specified, Kaspersky Secure Mail Gateway will not be receiving messages for your internal mail servers.
