无法连接到我的邮件服务器（java） [英] Unable to connect to my mail Server (java)

问题描述

public $ $ $ $ $ $ $ $ $ $ $ $ $ $ ication ication ication ication ication ication ication ication ication ication ication ication ication ication ication ication ication throw throw throw throw throw throw throw throw throw ication throw throw ication ication ication ication ication ication ication ication ication ication ication ication ication ication ication认证;

属性props = System.getProperties（）;
props.setProperty（mail.store.protocol，imap）;

会话session = Session.getDefaultInstance（props）;
Store store = session.getStore（imap）;

尝试{

store.connect（host，user，password）;
} catch（Exception e）{
e.printStackTrace（）;
}
}
}

得到这个错误..我几乎尝试使用所有协议

  javax.mail.MessagingException：Connection refused：connect; 
嵌套异常是：
 java.net.ConnectException：Connection refused：connect 
 at com.sun.mail.imap.IMAPStore.protocolConnect（IMAPStore.java:571）
 at javax.mail.Service.connect（Service.java:288）
在javax.mail.Service.connect（Service.java:169）
在ConnectGmail.main（ConnectGmail.java:26）
  

任何帮助??

解决方案

您需要启用邮件身份验证才能使用它：

设置属性 mail.smtp.auth 到 true 以进行身份​​验证。

如果为true，请尝试使用AUTH命令验证用户。默认为false。

@see Package com.sun.mail.smtp的Javadoc

public class ConnectGmail {

  public static void main(String args[]) throws Exception {


    PasswordAuthentication authentication;

    Properties props = System.getProperties();
    props.setProperty("mail.store.protocol", "imap");

    Session session = Session.getDefaultInstance(props);
    Store store = session.getStore("imap");

    try {

      store.connect(host , user , "password");
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}

Got this ERROR .. I almost tried with all the protocol

javax.mail.MessagingException: Connection refused: connect;
  nested exception is:
    java.net.ConnectException: Connection refused: connect
    at com.sun.mail.imap.IMAPStore.protocolConnect(IMAPStore.java:571)
    at javax.mail.Service.connect(Service.java:288)
    at javax.mail.Service.connect(Service.java:169)
    at ConnectGmail.main(ConnectGmail.java:26)

any help ??

解决方案

You need to enable the mail authentification before you can use it:

Set property mail.smtp.auth to true to enalbe authentification.

If true, attempt to authenticate the user using the AUTH command. Defaults to false.

@see Javadoc of Package com.sun.mail.smtp
