Hello all,

I have a hard time getting the following situation sorted out and would 
appreciate any input to solve it.
I'm in a firewalled LAN which provides a ssh-proxy to access outside
machines 
which I have to use like so:

1) build tunnel
ssh ProxyUser@SSHPROXY -L 2022:OUTSIDEBOX:22

2) make connection
ssh -X OutsideboxUser@localhost -p 2022

What I now wish to do is to access an outside mailserver (especially port
993) 
through this proxy and am stuck how to conceptually do this - build another 
tunnel through the tunnel?

If anybody can nudge me in the right direction, I would be very grateful.

Johannes
