Works fantastic with catch-all aliases, being able to compose or reply with a custom alias, and automatically selecting the correct alias when replying to an email. I've yet to find a provider's web interface that does this correctly, or allows you to do it at all. Gmail is hostile when it comes to alias / catch-all.
