Installing and configuring James
从Apache James官网可以下载到最新的版本。
我下载的是2.3.1的zip版本（我的是windows操作系统）。
解压到一个文件夹。这是解压出来的目录结构：
james-2.3.1
+---apps
+---bin
\---lib
+---conf
+---ext
+---lib
+---logs
+---tools
\---lib
运行bin里面的run.bat：
Using PHOENIX_HOME: E:\james-2.3.1
Using PHOENIX_TMPDIR: E:\james-2.3.1\temp
Using JAVA_HOME: C:\jdk1.5.0_06
Using PHOENIX_TMPDIR: E:\james-2.3.1\temp
Using JAVA_HOME: C:\jdk1.5.0_06
Phoenix 4.2
James Mail Server 2.3.1
Remote Manager Service started plain:4555
POP3 Service started plain:110
SMTP Service started plain:25
NNTP Service started plain:119
FetchMail Disabled
注意需配置好JRE的路径。运行成功后文件夹里将会生成一个文件夹：james，里面存放了配置文件等等。
主要的配置文件为app\james\SAR-INF下的config.xml，servername，dns等等都在这个文件配置。
修改好配置后，重新运行run.bat即可。
运行服务后，可以使用telnet命令登录进行管理：
C:\>telnet localhost 4555
默认的端口为4555，可在config.xml里面更改。

使用help命令可以获取命令列表：

| help | display this help |
| listusers | display existing accounts |
| countusers | display the number of existing accounts |
| adduser [username] [password] | add a new user |

关闭james服务可以使用CTRL+C，但是最适当的做法是登录到Remote Administration Tool使用shutdown命令进行关闭。
