Well as for the open web mail, sorry about that. I guess i wasn't reading the question properly. But as for any other suggestions, well i use the http protocol to check and send emails on the road. Basically just using the web browser. My web host provided me with email accounts that could be accessed by using http://webmail.example.com.
It would bring up an "Internet" interface for mail. I think it was called Horde. Sorry again. It's not exactly a solution to your original problem. Kind of a crude work around (that is if you have access to a webmail account provide by the web host).
