如何用clojure阅读我的电子邮件？

Question

I want to parse messages from my IMAP inbox with clojure.

I know there is clojure-mail library, but I do not have a gmail account. Thanks!

The Apache Commons IMAP client library is a reasonable choice. The core of their example program is trivially replicated in well under 20 lines of Clojure, if one doesn't bother with failure handling:

(ns mail-client.core
  (:import [org.apache.commons.net PrintCommandListener]
            [org.apache.commons.net.imap IMAPClient]))

(defn get-mail [server username password]
  (doto (IMAPClient.)
    (.setDefaultTimeout 60000)
    (.addProtocolCommandListener (PrintCommandListener. System/out true))
    (.connect server)
    (.login username password)
    (.setSoTimeout 6000)
    (.capability)
    (.select "inbox")
    (.examine "inbox")
    (.status "inbox" (into-array String ["MESSAGES"]))
    (.logout)
    (.disconnect)))
