Err, sorry.  You should stop this, as you now have an unencrypted
connection from your windows box to mail.iinet.net.au:110.

What's happening here is:

- winxp box listens on port 9999
- connections to winxp box port 9999 are forwarded over the ssh
  tunnel, and the linux box makes a connection to its localhost port
  9998.
- linux box listens on port 9998
- connections to linux box port 9998 are forwarded over the ssh tunnel
  back to the winxp box, which makes a connection to
  mail.iinet.net.au port 110.

The other solution (single forwarding) is the correct one:

  ssh -L 9999:mail.iinet.net.au:110 linuxbox

Apologies for getting this wrong in the first instance.
