Testing Inbound Mail When you have successfully tested an outbound mail message, you must
Deliverysend an inbound message to ensure that your router or firewall is properly configured to forward SMTP port 25 connections to the 3Com Email Firewall.
1Modify your Firewall or Router configuration to ensure that incoming SMTP port 25 connections are forwarded to the hostname or IP address of the 3Com Email Firewall.
2From an external mail address, send an email to an internal mail client.
3Check the Activity page of the 3Com Email Firewall to ensure the mail message shows up in the Mail Received Recently section. Click the Refresh button to provide an updated view.
In this scenario, the mail message should use the following route:
■External mail client to your Firewall/Router
■Firewall/Router to the 3Com Email Firewall
■3Com Email Firewall to the internal mail server
■Internal mail server to the internal mail client
If your message was not delivered, start with your external mail client and work your way along the route until the point at where the mail was not delivered to the next point.
When you have isolated the problem, modify your configuration and retry the test.
