Relay Domains

In order for Hermes SEG to deliver email, you must first set the domain(s) that Hermes SEG will process email for along with their corresponding email server(s). You can add as many domains and email servers as required. An email server can be configured as an IP address or a Host Name as long as the Hermes SEG can reach it over Port TCP/25. Multiple domains can be pointed to the same email server if necessary.

  2. In the Relay Domain field enter the domain name and in the Dest IP fields, enter the email server's IP address and click the Add button (Figure 1).
