POP3 proxy via ssh through server

I sometimes work behind a firewall at a corporate site. They blockout
outgoing port 110 for POP3 and that's a pain. I have SSH outbound
access and I have a dedicated server that I can use to proxy my POP3
traffic. My POP3 server is at an ISP that I do not have SSH into. I
am not always behind this firewall, so I want a flexible solution to
reach POP3 directly or through this proxy.

Is there a software I can run on MY server to accept an SSH connection
from my laptop behind the corporate firewall which will forward
unencrypted traffic to TCP port 110 at the destination POP3 server?

laptop (ssh outbound) -> corp f/w -> (ssh port) my server (POP3) ->
ISP POP3

Help appreciated.

SSH will do all you need: look at the -L option.

Paul, thanks for the note. Did you understand that I _do not_ have
SSH access privilege to the actual POP3 server? I can/need only SSH
from laptop through the firewall to my server. The actual network
conversation between the server and the POP3 box would be "normal"
POP3 traffic. Does your guidance still stand?

I take it you didn't look at the docs for info on the -L option then :-)
It will do what you require.
