Movemail options

Can `movemail' be run as a daemon like `fetchmail'?
I know that `mailutils' has `imap4d', but I don't grok exactly what
it does behind the scene.

What I want to achieve with `mailutils' is this:

- poll imap server at regular intervals to check for mail
- if mail is present, run `movemail' from emacs (or from my CLI)
- use emacs for in-out mail.

It would be nice if emacs had a minor-mode or whatever to do the
polling AND running movemail.

Thank!
