Unify your webmail.
If you have multiple webmail addresses Mail Forward is a clever way of unifying them all and receiving them in one place. It definitely saves you time and the hassle of signing in and out all the time.
Yet if you have a mail client like Outlook or Thunderbird, that application can already do the job for you, so Mail Forward wouldn't be much use. I'm also worried that, considering Gmail and Yahoo Mail are constantly improving (and already offer mail forwarding, albeit not for up to 20 accounts) this type of app could quickly become obsolete.

Good for synchronizing to one webmail.
