### 1.背景 ###

当我们搭建好james server后，所有操作都执行成功，foxmail作为客户端测试时，发送完文件，另一账号就是仍然收不到邮件， 而且编码使用javam mail 的IAMPFolder.appendMessages()也不能成功，非常纳闷，我也尝试了很久，尝试到怀疑人生，网上提问也未解决，详细请看[https://bbs.csdn.net/topics/392368913][https_bbs.csdn.net_topics_392368913]，最终还是在自己的努力下解决了。

### 2.分析问题 ###

在james服务端查看james-server.log日志发现报了如下错误：

        ... 85 more

发现是james服务本身报错，定位到位置为

org.apache.james.mailbox.store.StoreMessageManager.appendMessage(StoreMessageManager.java:311)

定位源码文件为StoreMessageManager 311行位置处的

file = File.createTempFile("imap", ".msg");

![70][]

此行意思为创建临时文件，单独编写代码测试，创建文件成功，输出为

C:\Users\Win10\AppData\Local\Temp\imap4466304417383536360.msg

测试代码如下：

package createTempFile;
    
    import java.io.File;
    import java.io.IOException;
    
    public class test {
    	public static void main(String[] args) {
    		try {
    			File file = File.createTempFile("imap", ".msg");
    			if (null != file) {
    				System.out.println(file.getPath());
    			}
    		} catch (IOException e) {
    			// TODO Auto-generated catch block
    			e.printStackTrace();
    		}
    	}
    }

输出：

![70 1][]

### 3.解决 ###

考虑到日志中提到：

ERROR 01:00:08,002 | james.mailprocessor | Exception calling ToSenderFolder: Unable to access mailbox.
    javax.mail.MessagingException: Unable to access mailbox.;

可能是用户权限问题造成不能成功创建文件。原来james收到邮件后创建临时消息，并在成功存储后进行删除，那到底是什么原因呢，经过多方查询，终于在james issues官网上查到bug原文地址：[https://issues.apache.org/jira/browse/JAMES-1514][https_issues.apache.org_jira_browse_JAMES-1514]

![70 2][]

其中解决方法为 petr在14年7月的回答：

    HI, it`s a JDK issue on Windows: the win-service is running as a local account and apparently can not access the user`s temp directory for temp-files creation.
    The easiest workaround is to set the java tempdir explicitely:
    -open <james-home>/con/wrapper.conf
    -add a WRITABLE temp directory on top of additional system properties:
    
    1.Java Additional Parameters
    wrapper.java.additional.15=-Djava.io.tmpdir=J:\tmp
    I haven`t played with windows-service accounts since my main target are ux-systems...

这是在windows上的jdk问题，windows上的服务作为本地用户运行，但是不能访问用户本省的temp文件目录进行临时文件的创建，最直接的方法是创建自己的java tempdir。

1.  打开james目录下conf/wrapper.conf
2.  添加有权限可写的临时文件目录到系统属性里面。我这里在C:\\Program Files\\james\\james-server-app-3.0.1目录下新建tmp文件夹

修改wrapper.java.additional.15=-Djava.io.tmpdir后的wrapper.conf如下所示：

此处由于启动是从bin目录启动，经测试写绝对路径会启动不起来，我这里是写的相对路径**../tmp**

修改完后,删除james生成的var目录，重新执行run.bat james start启动尝试，修复成功！
