;;; Commentary:

;; Note: Now mail.yahoo.com provides POP3 service, the webmail
;; fetching is not going to be supported.

;; Note: You need to have `url' and `w3' installed for this backend to
;; work. `w3' must be 4.0pre46+one-line-cookie patch or standalone
;; `url'.

;; Todo: To support more web mail servers.

;; Known bugs:
;; 1. Net@ddress may corrupt `X-Face'.

;; Warning:
;; Webmail is an experimental function, which means NO WARRANTY.
