The relay option allows our Elastix UCS System to send and receive e-mails from any computer connected to the Internet.
To configure a domain in order to send and receive e-mails, we go to the Email | Domains menu.
Add a new domain in the Create Domain link.
Write the domain name and press Save. Remember Elastix supports as many domains as desired.
To set the Relay option, go to the Email | Relay menu. This option allows a network to send e-mails to external domains through our Elastix system. It is important to insert the network and the Netmask. For example, in the following screenshot, we will allow the networks 192.168.1.0 with Netmask 255.255.255.0 and 172.16.102.0 with Netmask 255.255.254.0.
