Port Forwarding with Microsoft Outlook
Port forwarding offers a quick and easy way of keeping your personal and company email private and secure. The following instructions will help you quickly configure your TinyTERM product and Outlook to work together to keep your email secure.
When using port forwarding, there are two external hosts that you will be communicating with: the secure host that is running SSH, and the unsecure host that handles email. These instructions will configure your desktop or laptop system to send and receive email over the secure host, who will communicate with the unsecure mail server. In some cases, the mail server will be running on the same secure server as SSH. In this case, you'll use the same host names for both.
In the examples below, mailhost.com is used to represent your mail server, and securehost.com is used to represent the secure server running SSH.
To configure your TinyTERM product for port forwarding, you need to first establish a secure connection/session with your secure server. To do this, launch TinyTERM and then select Edit|Session Properties... to display the Session Properties menu.
Next, you need to secure your outbound SMTP connection. Select Edit|Session Properties... to display the Session Properties menu. Click on the "Port Forwarding" tab.
Next, you need to secure your inbound POP3 connection.
Now that TinyTERM is setup for port forwarding, you need to configure Outlook to operate through your new secure connection. Launch Outlook, and select Tools|Accounts... to view a list of your active email accounts.
Now you'll configure your email account to use the secure ports.
If your secure server is different from your mail server, you may need to configure the outgoing mail server for authentication.
You are now setup to send and receive email over a secure, encrypted channel!
It is important to remember that TinyTERM must be running and a session established with your secure server in order for port forwarding to work properly. If TinyTERM is not running, or you don't have a session established, Outlook will be unable to retrieve your email and will respond with "Mail Delivery Error" messages.
The server names used above should be changed to the names or IP addresses of your actual secure server and mail server. The 10025 and 10110 port numbers used in the examples may be changed to anything above 1024. Port 25 is assigned to be the SMTP server and must not be changed. Likewise, port 110 is assigned to the POP3 server and must not be changed.
