Well, I have exactly the same problem. And my solution to this is to use
a TCP forwarding via an SOCKS proxy.

  ssh -D7777 somehost

creates a SOCKS proxy on your local machine on port 7777. You can use
that now with your favourite application (capable connecting via SOCKS
proxies) or you can force your application to direct every TCP packet
through the proxy. I prefer the latter since I don't like to reset my
apps everytime I everytime the state of beeing behind a firewall changes.
I achieve this by using "tsocks". I tiny tool which forces programs to
use the provided SOCKS proxy (it's transparent).

So just install "tsocks", configure it accordingly (should be just a few
lines) and start your application like "tsocks evolution".

I hope that works for you as well.

Cheers,
