Question

我正在使用javamail，我尝试使用身份验证，或者没有，但它不起作用。有人可以帮忙吗？

 private boolean InitMailer(String sSMPTGateWay)
{
    try
    {
        oProps=new Properties();
        oProps.put("mail.smtp.host",sSMPTGateWay);
        //oProps.put("mail.smtp.socketFactory.port", "465");
        //oProps.put("mail.smtp.port", "465");
        oProps.put("mail.smtp.starttls.enable", "true");

      //  oProps.put("mail.smtp.socketFactory.class",
    //      "javax.net.ssl.SSLSocketFactory");
    oProps.put("mail.smtp.auth", "true");
    //oProps.put("mail.smtp.port", "465");

        Authenticator auth = new javax.mail.Authenticator() {
                            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("mmyemail@gmail.com","mypassword");
            }
        };

        oSession=Session.getInstance(oProps,auth);
        oSession.setDebug(true);
        oTransport=oSession.getTransport(oSession.getProvider("smtp"));
        System.out.println("tento di connettermi");
        oTransport.connect();
        System.out.println("connesso?");
        if(!oTransport.isConnected())
        {
            ErrorLog.warningLog("MService: MService(): Mail Server "+sMailGateWay+" non operativo. Tento un altro Gateway.");
            return false;
        }
   }
    catch(Exception e)
    {
        e.printStackTrace();
        ErrorLog.warningLog("MService: MService(): Mail Server "+sMailGateWay+" non operativo. Tento un altro Gateway.");
        return false;
    }
    return true;
}

private void sendMessage(String sFrom,String sTo,String sSubject,String sBody) throws Exception
{
        if(Constants.ENABLE_MAIL_SERVICE.equals("NO"))
        {
            ErrorLog.warningLog("Tentativo di invio, Mail disabilitata: \n From:"+sFrom+"\n To:"+ sTo +"\n Subject: "+sSubject + "\n Body:\n"+sBody);
            return;
        }
        if(Constants.ENABLE_MAIL_SERVICE.equals("TEST"))
            sTo=Constants.TEST_MAIL;

        MimeMessage msg=new MimeMessage(oSession);
        msg.setFrom(new InternetAddress(sFrom));
        msg.addRecipient(Message.RecipientType.TO,new InternetAddress(sTo));
        msg.setSubject(sSubject,"iso-8859-1");
        msg.setSentDate(new Date());
        msg.setText(sBody,"iso-8859-1");
        System.out.println("mando mex");
        oTransport.send(msg);
}

这是错误，这不是错误，但电子邮件未发送

Answer 1

修复所有这些common JavaMail mistakes，你会得到更多。特别是，调用oTransport.sendMessage而不是oTransport.send。

Answer 2

当您使用本地smtp服务器时，有时候您的ISP会阻止端口25

如果您使用的是主机提供商提供的SMTP服务器，则需要验证用户名和密码。 javax.mail.PasswordAuthentication类用于验证密码。

尝试更改properties.put("mail.smtp.port", "25");

到properties.put("mail.smtp.port", "587"); // 465 also option

检查您是否未获得任何解决方案Java mail mistakes

Answer 3

您发布的错误与属性有关。改变它。

    oProps.put("mail.smtp.auth", "true");
    oProps.put("mail.smtp.starttls.enable", "true");
    oProps.put("mail.smtp.host", "smtp.gmail.com");
    oProps.put("mail.smtp.ssl.trust", "smtp.gmail.com");
    oProps.put("mail.smtp.port", "587");

我无法使用javamail发送电子邮件
