+;;; 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.
