Creating the Tunnel required for the Email Connection is a simple process. As we indicated before, we have separate
Entries for POP3 (Post Office Protocol 3), IMAP (Internet Mail Access Protocol - Revised POP3), and SMTP (Simple Mail Transport Protocol).
The design for creating the Tunnel is simple, define a port Locally which PuTTY can Encrypt and Forward to the Remote Server.
In this case, we are using the Actual Port (POP3-110, IMAP-143, and SMTP-25) Plus 3000, to map a local port number to the actual port number.
Using the template illustrated, you define the Local Port Number, and the Server Name : Actual Port number to create the defined Tunnel for use.
Simply add the three port definitions for the Tunnels. When you have created the three definitions, you will need to select the Session Category
and then click the Save Button to save the definitions for use.
