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 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 domains to which the email messages are addressed and then enter the IP addresses or fully qualified domain names (FQDN) to which Kaspersky Secure Mail Gateway must redirect messages addressed to these domains.
Example: To redirect messages addressed to the "example.com" domain to the 192.168.0.1:25 address:

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 receives email messages from any sources, including untrusted ones. Kaspersky Secure Mail Gateway receives messages from untrusted sources only for the domains you specified. Messages from untrusted sources sent to other domains are rejected.
If local domains are not specified, Kaspersky Secure Mail Gateway will not be receiving messages for your internal mail servers.
