SMTP client library for Clojure. That’s it.
Tarayo is heavily inspired by drewr/postal.
-
Only targets SMTP
-
Provide only one feature.
-
Use drewr/postal for
sendmail.
-
-
Explicit connection
-
Handle the connection manually.
-
-
Well tested
"Tarayo" is a tree name called "Tree of post office" in Japan.
(require '[tarayo.core :as tarayo])
;; => niltarayo.core/connect is a function to connect SMTP server.
You need to call tarayo.core/close function before quitting, or use with-open macro.
(type (tarayo/connect {:host "localhost" :port 25}))
;; => tarayo.core.SMTPConnectionOther examples are follows:
- SSL connection
-
(tarayo/connect {:host "localhost" :port 465 :ssl.enable true}) - TLS connection
-
(tarayo/connect {:host "localhost" :port 587 :starttls.enable true}) - Connection with user authentication
-
(tarayo/connect {:host "localhost" :port 25 :user "USERNAME" :password "PASSWORD"})

{:content (java.nio.file.Files/readAllBytes (.toPath (io/file "test/resources/image.png")))

;; => {:result :success, :code 250, :message "250 OK\n"}Like above, tarayo only supports SMTP, but you can also use for generating parameter to call Gmail API.
The entire email message in an RFC 2822 formatted and base64url encoded string. Returned in messages.get and drafts.get responses when the format=RAW parameter is supplied.
To generate this parameter, you can use tarayo.mail.mime.
(require '[tarayo.mail.mime :as mime]
'[tarayo.mail.session :as session])
;; => nil
(defn- mime-message->raw-string [^jakarta.mail.internet.MimeMessage mime-msg]
(let [buf (java.io.ByteArrayOutputStream.)]
(.writeTo mime-msg buf)
(org.apache.commons.codec.binary.Base64/encodeBase64URLSafeString (.toByteArray buf))))
;; => any?
(let [msg {:from "[email protected]"
:to "[email protected]"
:subject "hello"
:body "world"}
mime-msg (mime/make-message (session/make-session) msg)]
(mime-message->raw-string mime-msg))
;; => string?Example using shrubbery.
(require '[shrubbery.core :as shrubbery])
;; => nil
(let [conn (shrubbery/stub
tarayo/ISMTPConnection
{:send! "ok"
:connected? true
:close true})]
(tarayo/send! conn "foo"))
;; => "ok"Copyright 2020-2023 Toyokumo,Inc.
