Bring up the "Connect using Password Authentication" window. Make sure yip.org (or whichever host name you've used) is selected in the Host Name pulldown menu.
Click on Properties. Go into the Forward tab, and ensure that the radio button under "Forwarded TCP/IP Connections" is set to Local. Then click on the New... button.
For POP3, follow these directions. The following sequence is a bit fuzzy due to the fact that I'm going on nothing but the documentation to make this. It should ask you for a name for the forward; enter POP3 or some name you want to appear in the list on the Forward tab. Next, it should ask you for the source port; enter "110" without the quotes. When it asks for the destination host, enter "yip.org". Then tell it that the destination port is "110". And finally, ensure that the box has a checkmark beside "Allow Local Connection Only".
For IMAP, follow these directions. The following sequence is a bit fuzzy due to the fact that I'm going on nothing but the documentation to make this. It should ask you for a name for the forward; enter IMAP or some name you want to appear in the list on the Forward tab. Next, it should ask you for the source port; enter "143" without the quotes. When it asks for the destination host, enter "yip.org". Then tell it that the destination port is "143". And finally, ensure that the box has a checkmark beside "Allow Local Connection Only".
You may have to restart your ssh program after adding the forward. Screenshots coming soon.
