Configuring Guardian Digital Mail Suite

For this manual all examples will apply a real-life setup. The setup being used will have a main SMTP server which will act as a mail relay to a mailbox/spool server that stores the mail. The following diagram outlines this configuration:

We will be using the 192.168.50.0/24 network
(corp.guardiandigital.com) for our example. The two mail servers will be  
 
192.168.50.2 (smtp.corp.guardiandigital.com)  
192.168.50.3 (mailbox.corp.guardiandigital.com)

Generally these two mail servers will be the only mail servers located on the network they are on and will be protected by a firewall. Additionally, depending on the network configuration, DNS service may be required. However, both the configuration of a firewall and DNS is beyond the scope of this document.

• [NOTE:]The network 192.168.50.0/24 is being displayed in CIDR notation. For an explanation of this method refer to Appendix on page .
