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，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：

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");

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：

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

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 /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！
