Question

我在Openshift Free（redhat webhotel）上运行了一个web应用程序。从这个应用程序，我想通过我的Gmail帐户发送电子邮件与javax.mail-api。当我尝试从我的开发人员计算机上运行我的代码尝试时，它既可以使用SSL，也可以不使用SSL。但是当我从openhift服务器中的JSP页面运行它时，它不起作用。我从gmail那里得到了这个回复：

以下是没有SSL的代码：

public static void sendGmail(String to, String subject, String text) throws AddressException, MessagingException
{
    final String SMTP_HOST = "smtp.gmail.com";
    final String SMTP_PORT = "587";
    final String GMAIL_USERNAME = "xxx@gmail.com";
    final String GMAIL_PASSWORD = "xxx";

    System.out.println("Process Started");

    Properties prop = System.getProperties();
    prop.setProperty("mail.smtp.starttls.enable", "true");
    prop.setProperty("mail.smtp.host", SMTP_HOST);
    prop.setProperty("mail.smtp.user", GMAIL_USERNAME);
    prop.setProperty("mail.smtp.password", GMAIL_PASSWORD);
    prop.setProperty("mail.smtp.port", SMTP_PORT);
    prop.setProperty("mail.smtp.auth", "true");

    Session session = Session.getInstance(prop, new Authenticator()
    {
        protected PasswordAuthentication getPasswordAuthentication()
        {
            return new PasswordAuthentication(GMAIL_USERNAME,
                    GMAIL_PASSWORD);
        }
    });
    session.setDebug(true);


    MimeMessage message = new MimeMessage(session);

    message.setFrom(new InternetAddress(GMAIL_USERNAME));
    message.addRecipients(Message.RecipientType.TO,InternetAddress.parse(to));
    message.setSubject(subject);
    message.setText(text);
    message.setRecipients(Message.RecipientType.TO,InternetAddress.parse(to));
    Transport transport = session.getTransport("smtp");
    transport.connect(SMTP_HOST, GMAIL_USERNAME, GMAIL_PASSWORD);
    transport.sendMessage(message, message.getAllRecipients());
}

以下是使用SSL的代码：

public static void sendGmail(String to, String subject, String text) throws AddressException, MessagingException
{
    String host = "smtp.gmail.com";
    final String GMAIL_USERNAME = "xxx@gmail.com";
    final String GMAIL_PASSWORD = "xxx";

    Properties props = new Properties();
    props.put("mail.smtps.host", host);
    props.put("mail.smtps.auth", "true");
    Session session = Session.getInstance(props, null);
    session.setDebug(true);
    MimeMessage msg = new MimeMessage(session);
    msg.setSubject(subject);
    msg.setText(text);
    msg.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
    msg.setFrom(new InternetAddress(username));
    msg.setHeader("X-Mailer", "smtpsend");
        msg.setSentDate(new Date());

        SMTPTransport t = (SMTPTransport)session.getTransport("smtps");

    try
    {
        t.connect(host, username, password);
        t.sendMessage(msg, msg.getAllRecipients());
    } 
    finally
    {
        t.close();
    }
}

正如您所看到的，我在会话的调试模式下运行我的尝试，所以下面是我尝试的输出：

你们有什么线索为什么我的openhift服务器无法正常工作？

祝你好运弗雷德里克

Answer 1

感谢您的帮助。好像我需要在我的Gmail帐户中激活IMAP。之后它运作良好。

祝你好运弗雷德里克

Answer 2

我在gmail方面遇到了一些困难，因此我转而使用SendGrid将JavaMail集成到部署在OPENSHIFT上的虚拟项目的Web应用程序中。我使用了SendGrid试用版。

一些变化 -

           // The SendGrid SMTP server.
             String SMTP_HOST_NAME = "smtp.sendgrid.net";

              Properties   properties = new Properties();
              // Specify SMTP values.
              properties.put("mail.transport.protocol", "smtp");
              properties.put("mail.smtp.host", SMTP_HOST_NAME);
              properties.put("mail.smtp.port", 587);
              properties.put("mail.smtp.auth", "true");

你必须要这两个 -

final String sendGridUser ="NameUChoose"; // Use At SendGrid Registration
   final String sendGridPassword="*****" ; // Use At SendGrid Registration

其余部分与其他JavaMail代码几乎相同。

您还必须验证您的凭据，所以 -

           // Create the authenticator object.
              Authenticator authenticator = new SMTPAuthenticator();

创建一个单独的java类，如 -

package com.rana;

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;

public class SMTPAuthenticator   extends Authenticator
{
    final String sendGridUser ="NameUChoose";
    final String sendGridPassword="*******;
       public PasswordAuthentication getPasswordAuthentication()
       {
            String username = sendGridUser;
            String password = sendGridPassword;

            return new PasswordAuthentication(username, password);   
       }


}

如何从openshift服务器内部通过gmail-account发送带有javamail的电子邮件？
