Mail client in Python?

[Ken D'Ambrosio]

Idle curiosity: is there a (decent) IMAP mail client (web or local)
written in Python? I've got a project that needs doing, and it just
occurred to me that a mail client might be the ideal interface; I'd have
to change some back-end stuff (to do database queries instead of IMAP or
POP queries), but could save myself a huge amount of work re-creating the
wheel.

Thanks for any recommendations!
