The relaying problem gets solved and additionally you get *real* security in your email reading too. If you're using Windows on your laptop (can't blame you -- I do), you can try PuTTY, "a free Win32 Telnet/SSH client", that has port forwarding capabilities: http://www.chiark.greenend.org.uk/~sgtatham/putty/ Let me know if you need help setting up an ssh(1) tunnel.
