Play Framework使用Apache Commons發送電子郵件

Question

我正在嘗試創建一個頁面，在Play Framework上發送帶附件的電子郵件。 我首先需要知道如何發送簡單的電子郵件。 我正在關注Apache Commons Userguide for Email 。

   Email email = new SimpleEmail();
        email.setHostName("smtp-mail.outlook.com");
        email.setSmtpPort(587);
        email.setAuthenticator(new DefaultAuthenticator("email@outlook.com", "password"));
        email.setSSLOnConnect(true);
        email.setFrom("user@outlook.com");
        email.setSubject("Subject");
        email.setMsg("This is a test mail ... :-)");
        email.addTo("add@outlook.com");
        email.send();

執行異常： [EmailException: Sending the email to the following server failed : smtp-mail.outlook.com:465]

我不知道為什么它說465甚至我將端口設置為587

終端上的異常： Caused by: com.sun.mail.util.MailConnectException: Couldn't connect to host, port: smtp-mail.outlook.com, 465; timeout 60000; Caused by: com.sun.mail.util.MailConnectException: Couldn't connect to host, port: smtp-mail.outlook.com, 465; timeout 60000;

程序接受端口號為465的原因是什么。

使用gmail時也會出現同樣的問題

It's answered in http://stackoverflow.com/questions/26393906/error-sending-email-with-gmail.

You have to login to "https://www.google.com/settings/security/lesssecureapps" for google and enable then run the program. It works.

If it's not enabled we get the following exception 
org.apache.commons.mail.EmailException: Sending the email to the following server failed : smtp.googlemail.com:465
