Question

我最近将电子邮件移至Google Apps。现在，我可以通过登录gmail.com上的电子邮件帐户查看和发送邮件。

sales@example.com，现在我正在尝试发送SMTP电子邮件，这些电子邮件在较旧的托管上使用以前的SMTP设置正常工作。

这是我的代码

Properties props = new Properties();
        props.setProperty("mail.transport.protocol", "smtp");
        props.setProperty("mail.host", "smtp.gmail.com");
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.port", "465");
        props.put("mail.debug", "true");
        props.put("mail.smtp.socketFactory.port", "465");
        props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        props.put("mail.smtp.socketFactory.fallback", "false");

        Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("sales@example.com", "my-new-password-on-gmail");
            }
        });

这是我看到的错误

港口号码465用于启用SSL（smtps）。其属性如下：

        properties.put("mail.smtps.host", "smtp.gmail.com");
        properties.put("mail.smtps.port", "465");
        properties.put("mail.smtps.auth", "true");
        properties.setProperty("mail.smtp.ssl.enable", "true");
        properties.setProperty("mail.transport.protocol", "smtps");

对于港口号。 587

    properties.put("mail.smtp.host", "smtp.gmail.com");
        properties.put("mail.smtp.port", "587");
        properties.setProperty("mail.smtp.starttls.enable", TRUE);
        properties.setProperty("mail.smtp.starttls.required", TRUE);
        properties.setProperty("mail.smtp.ssl.enable", "false");
        properties.setProperty("mail.transport.protocol", "smtp");

有效。！
