无需身份验证即可在javax.mail中发送邮件

Question

我使用javax.mail在Java中发送邮件.既然我的项目概念的一部分发生了变化,我必须发送邮件而不进行身份验证.我将不得不改变我的createSession()方法:

private void createSession() {
    properties.put("mail.smtp.auth", "true");
    properties.put("mail.smtp.starttls.enable", "true");
    properties.put("mail.smtp.host", server);
    properties.put("mail.smtp.port", port);

    session = Session.getInstance(properties, new javax.mail.Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(username, password);
        }
    });
}

这是相当明显的是,我应该换mail.smtp.auth到false,但我还需要改变？

Answer 1

private void createSession() {
    properties.put("mail.smtp.auth", "false");
     //Put below to false, if no https is needed
    properties.put("mail.smtp.starttls.enable", "true");
    properties.put("mail.smtp.host", server);
    properties.put("mail.smtp.port", port);

    session = Session.getInstance(properties);
}

我想,这就足够了.
