Hey guys.. sorry if this isn't the ideal position for this topic. Please move where you see fit.

Anyway, I'm looking for an e-mail client.. but here's the thing: I want it to show me what's in my inbox without taking the emails away.

Example of what I DONT want:
If I set up a web based email account (Yahoo for example) and use Eudora to check it, the emails show up on Eudora. If I would want to go someplace else and want to check my email on the actual web-based "option", the emails are gone from there. They are no longer on the server. Is there any way I could use an email client (for checking multiple addresses, primarily) but still have the option of reading older emails through the web?

I'm looking either for options to change or a program that keeps the emails on the server.

Much thanks
