RevMen,
I was looking for a similar thing but more for getting advanced e-mail features along with e-mail history. I was just about to post my own e-mail related question but saw yours.
Anyways, here is a free program that will allow you to preview e-mails that you have waiting for you in, up to, 10 different e-mail accounts. You can delete them from the mail server without downloading them or leave them be.

I haven't tried it yet because it needs a support program beyond .net called "OpenNETCF". The link is on his page so everything that you need is there.
