Step 2. Configuring email routing (transport_map)

Configure email routing at this step.

By default, Kaspersky Secure Mail Gateway uses the settings of your DNS server for email routing. To configure email routing manually, create a transport map: enter the names of the domains for which email messages are intended and then type the IP addresses or FQDN names of the domains to which Kaspersky Secure Mail Gateway will be redirecting messages intended for the domains.

For example, if you want messages intended for the example.com domain to be redirected to the address 1.1.1.0:25, add the example.com domain to the transport map and then specify the IP address 1.1.1.0 and port number 25 for routing messages intended for the example.com domain.

To configure email routing:

1. Click the Add a record to the transport map link to open the Email routing window.
2. In the Enter domain name field, type the name of the domain for which email messages are intended.

   Type the domain names in FQDN format.

3. In the Enter email destination address (IPv4, domain name or FQDN) field, type the IP address or domain name of the server the routing of email to which you want to configure.

   You can enter an IPv4 address (for example: 192.0.0.1 or 192.0.0.0/16), an IPv6 address (for example: 2607:f0d0:1002:51::4), subnet mask in CIDR format (for example: fc00::/7), domain name or FQDN.

4. In the Enter the port number to connect with the email destination address, select the port number.

   The default value is 25.

5. Select one of the following options:
   • Do not enable MX lookup.
   • Enable MX lookup (for domain names or FQDNs).
6. Click OK.

   The Email routing window closes.

Transport map records are added one at a time. Repeat the process of adding records to the transport map for all records that you are adding.

Proceed to the next step of the wizard.
