POP3 Gmail access with Clojure and JavaMail

I recently had the need to access gmail using Clojure. I used JavaMail to accomplish this via pop3. Below is some code that I wrote to help me get emails. Hope you find it useful Enjoy 🙂


(use '[clojure.contrib.duck-streams])
(def props (System/getProperties))
; Get the default Session object.
(def session (javax.mail.Session/getDefaultInstance props))

; Get a Store object that implements the specified protocol.
(def store (.getStore session "pop3s"))

;Connect to the current host using the specified username and password.
(.connect store "pop.gmail.com" "username@gmail.com" "password")

;Create a Folder object corresponding to the given name.
(def folder (. store getFolder "inbox"))

; Open the Folder.
(.open folder (javax.mail.Folder/READ_ONLY ))
; Get the messages from the server
(def messages (.getMessages folder))

(defn getFrom [message](javax.mail.internet.InternetAddress/toString (.getFrom message)))
(defn getReplyTo [message] (javax.mail.internet.InternetAddress/toString (.getReplyTo message)) )
(defn getSubject [message] (.getSubject message))

;print out the body of the message
(for [m messages] (read-lines(.getInputStream m)) )

;;;;;code for sending an email

(def props (System/getProperties))
(. props put "mail.smtp.host", "smtp.gmail.com")
(. props put "mail.smtp.port", "465")
(. props put "mail.smtp.auth", "true")
(. props put "mail.transport.protocol", "smtps")

(def session (javax.mail.Session/getDefaultInstance props nil))
(def msg (javax.mail.internet.MimeMessage. session))
(. msg setFrom (javax.mail.internet.InternetAddress. "sender@gmail.com"))
(. msg addRecipients javax.mail.Message$RecipientType/TO
"receiver@gmail.com")

(. msg setSubject "i am the subject")
(. msg setText "I am the body!!!")

(. msg setHeader "X-Mailer", "msgsend")
(. msg setSentDate (java.util.Date.))

; send the email
(def transport (. session getTransport))
(. transport connect "smtp.gmail.com" 465 "sender@gmail.com" "password")
(. transport sendMessage msg (. msg getRecipients javax.mail.Message$RecipientType/TO))
(. transport close)
