Gmail now lists email forwarding and POP3 access on it’s about page:

While I’m quite happy with my Exim+Mutt setup, all this talk of Gmail made me create an account and check out what’s good about it (other than the 1GB of space). I was thinking of putting a webmail system on top of our IMAP/POP3 setup, but SquirrelMail just can’t compare to Gmail. Maybe I should spend some more time checking other open source webmail packages.
