Mail Fetching Not Happening?

I'm evaluating SC for use in our organization. We're really excited about the mail fetching and how we can combine that with a web form and business rules to generate new requests. However whenever I turn Mail Fetching on, it doesn't seem to fetch anything. I set up a test account and sent it a message, but SC is never getting it. I've left it checking mail for 20 minutes without stopping it, and it's set to check the mail every one minute.

The "Mail Fetching Status" line always says: "Last attempt to fetch mail : -"

Here are the relevent lines from the log (as near as I can tell):

Any thoughts?
