iPrism uses the SMTP protocol to support sending or receiving, via email:
Reports
Alerts (on monitored activity)
System Notifications (upgrades, filter list problems, registration)
Access Requests (request access button on block page)
By default, iPrism will perform a DNS (MX record) lookup to deliver these emails if no mail relay is specified. If iPrism is installed in a network where a DNS server is not available or a DNS MX record lookup is not desirable, messages can be sent directly to a Mail Server or SMTP "Smarthost" via IP using the iPrism "SMTP Relay" function.
The destination IP of the destination Mail Server or SMTP "Smarthost" (if used, typically for efficiency) can be configured in the SMTP Relay field (shown below). If SMTP Relay is a "Smarthost," iPrism will delegate the delivery of the email to the relay and not attempt to directly contact the recipient's Mail Server.
Important: if required, ensure iPrism's IP address is allowed to relay through the SMTP Relay host.
Go to System > Networking > SMTP Relay frame
Enter the IP address of the SMTP Relay
Important: It is strongly recommended that you check SMTP Relay functionality using email diagnostics, see:
