When I'm at work, Yahoo webmail is blocked, but I can still preview a short list of emails on the Yahoo homepage by hovering over the envelope. My request to Yahoo is to show more info (list more messages, and much more text for each email) and make it possible to delete email (e.g. a little 'x' next to the email title). This way, my employer stays 'safe' and I remain 'connected' to my contacts.
