Try this
试试这个
props.put("mail.smtp.host", host);
props.put("mail.smtp.auth", "true");
props.put("mail.debug", "false");
props.put("mail.smtp.port", port);
And while creating session use this authentication code
在创建会话时使用此身份验证代码
l_session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
l_session.setDebug(true);

Our environment is running under WebSphere 7. To support secured smtps, correct variant to turn on SMTPS AUTHorization is:
我们的环境在 WebSphere 7 下运行。为了支持安全的 smtps，打开 SMTPS AUTHorization 的正确变体是：
"mail.smtps.auth=true"
“mail.smtp s.auth=true”
Actually, according to decompiled sources, before authorizing the mail session WebSphere checks if there is a property composed as: "mail."+ transportProtocol + ".auth" set to "true". This helped me to send emails via gmail.
实际上，根据反编译的来源，在授权邮件会话之前，WebSphere 会检查是否有一个属性组成为：“mail.”+ transportProtocol + “.auth” 设置为“true”。这帮助我通过 gmail 发送电子邮件。
