Step D: Check the Hosts File
If your network is not configured with DNS, you also need to add a static entry to the hosts file on your AWS Elemental Delta node. To do so:
To check the hosts file
-
Open the file
/etc/hosts
in Nano as shown here:sudo nano /etc/hosts
You see something similar to this:
132.0.0.1 SYS-1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 SYS-1 localhost localhost.localdomain localhost6 localhost6.localdomain6
-
Add a line to the end of the file that has the IP address of the relay server, a space, and the hostname of the relay server as shown below.
192.0.2.0 ExampleMailHostname
-
Use the keys Ctrl+o to save the file, then Ctrl+x to exit Nano.
