Java Mail 从交换服务器获取带有 pop3 的邮件 => 线程 "main"javax.mail.MessagingException 中的异常

Question

以下代码从交换电子邮件帐户获取邮件:

public class TicketMain {

    /**
     * @param args
     */
    public static void main(String[] args) throws Exception {
        final Properties props = new Properties();

        //XTrustProvider.install();

       // System.setProperty("sun.security.ssl.allowUnsafeRenegotiation", true);

        props.setProperty("mail.pop3.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        props.setProperty("mail.pop3.socketFactory.fallback", "false");
        props.setProperty( "mail.pop3.host", "10.30.0.103" );
        props.setProperty( "mail.pop3.user", "xxxx");
        props.setProperty( "mail.pop3.password", "xxxx!");
        props.setProperty( "mail.pop3.ssl.enable", "true");
        props.setProperty( "mail.pop3.port", "445" );
        props.setProperty( "mail.pop3.auth", "true" );      
        props.setProperty("mail.pop3.starttls.enable", "false"); 
       /* props.setProperty( "mail.pop3.starttls.enable", "true" );
        props.setProperty( "mail.pop3.starttls.required", "true" );*/

        Session session  = Session.getInstance(props);
        session.setDebug(true);



        Store store = session.getStore("pop3");
        store.connect("xxxx", "xxxx!");         
        Folder folder = store.getDefaultFolder();
        folder.open(Folder.READ_ONLY);
        Message message[] = folder.getMessages();
        for ( int i = 0; i < message.length; i++ )
        {
          Message m = message[i];
              System.out.println( "-------------------------\nNachricht: " + i );
              System.out.println( "From: " + Arrays.toString(m.getFrom()) );
              System.out.println( "Topic: " + m.getSubject() );   


          if ( m.isMimeType("text/plain") )
            System.out.println( m.getContent() );
        }
        folder.close( false );
        store.close();

    }

}

执行此应用程序时出现以下错误:

SSL 证书已导入到 java keystore 中。

这里有什么问题吗？

telnet 主机端口 正在从客户端工作。

Answer 1

您正在尝试建立到纯文本 POP3 端口而非 POP3S 端口的 SSL/TLS 连接。

因此，如果您想使用 SSL/TLS，您必须启用 starttls 但禁用 ssl。

    props.setProperty("mail.pop3.ssl.enable", "false");
    props.setProperty("mail.pop3.starttls.enable", "true"); 
    props.setProperty("mail.pop3.starttls.required", "true");
