在windows平台使用Apache James搭建邮件服务器以及使用C#向外网发送邮件

首先环境搭建：

1、下载安装JDK，并且配置环境变量

2、下载Apache James ，下载解压之后的目录如图

双击bin下边的run.bat批处理文件安装James 服务，提示如下信息说明安装成功：

Using PHOENIX_HOME:   C:\james
Using PHOENIX_TMPDIR: C:\james\temp
Using JAVA_HOME:

Phoenix 4.0.

james 2.3.2.1
Remote Manager Service started plain:
POP3 Service started plain:
SMTP Service started plain:
NNTP Service Disabled
Fetch POP Disabled

安装之后如图所示：

修改E:\james-2.3.2.1\apps\james\SAR-INF\config.xml文件

将配置文件中的

········

<postmaster>Postmaster@localhost</postmaster>

···········

 <servernames autodetect="false" autodetectIP="false">

<!-- CONFIRM? -->

         <servername>localhost</servername>

      </servernames>

中的localhost修改为自己的域名，这里假设修改为star.com，如果开通账号为zsf的话那么邮件地址就是zsf@star.com，并且将autodetectIP修改为false。修改结果如下：

·····

<postmaster>Postmaster@star.com</postmaster>

······

<servernames autodetect="false" autodetectIP="false">

<!-- CONFIRM? -->

         <servername>star.com</servername>

      </servernames>

找到配置项：

<mailet match="RemoteAddrNotInNetwork=127.0.0.1" class="ToProcessor">
    <processor> relay-denied </processor>
    <notice>550 - Requested action not taken: relaying denied</notice>
</mailet> 

注释掉该配置项

找到下面的配置项，去掉注释：

<authRequired>true</authRequired>

这样的话访问邮箱就需要账号验证才行。

在控制台中输入命令行telnet localhsot 4555 进入James的控制台

提示输入Login ID和Password

Login ID 和Password在之前修改的配置文件中设置，找到节点

 <account login="root" password="!changeme!"/>

root就是Login ID,可以在此处修改登录的账号密码。登录成功之后提示：

Welcome root. HELP for a list of commands

输入 help 就可以查看James的相关命令

输入 adduser liemei 123456 回车就可以添加一个新的用户，用户的邮箱就是liemei@star.com，

账号就是liemei 密码是123456。

到目前为止基本的Apache James配置已经完成，但是要向外网如163邮箱发送邮件，还有一些问题，因为James的SMTP 服务默认在 25 端口启动，POP3 服务默认在 110 端口启动， NNTP 服务默认在 119 端口启动，所以如果想要在外网正常使用需要配置防火墙允许这些端口通过，配置的位置在防火墙高级设置，添加入站规则，如图

下一步就是在路由器中配置对应的外网映射，将域名star.com对应的外网IP地址映射到邮件服务器上，端口一一对应即可。

使用C#发送邮件测试

string senderServerIp = "xxx.xx.xx.x";  //域名star.com对应的外网IP

                string toMailAddress = "liushuaichao159@163.com";

                string fromMailAddress = "liemei@star.com";

                string subjectInfo = "Test sending e_mail";

                string bodyInfo = "Hello Eric, This is my first testing e_mail";

                string mailUsername = "liemei";

                string mailPassword = "123456"; //发送邮箱的密码（）

                string mailPort = "25";

                string attachPath = "";

                MyEmail email = new MyEmail(senderServerIp, toMailAddress, fromMailAddress, subjectInfo, bodyInfo, mailUsername, mailPassword, mailPort, false, false);

                email.AddAttachments(attachPath);

                email.Send();

发送邮件类：

 class MyEmail
    {
        private MailMessage mMailMessage;   //主要处理发送邮件的内容（如：收发人地址、标题、主体、图片等等）
        private SmtpClient mSmtpClient; //主要处理用smtp方式发送此邮件的配置信息（如：邮件服务器、发送端口号、验证方式等等）
        private int mSenderPort;   //发送邮件所用的端口号（htmp协议默认为25）
        private string mSenderServerHost;    //发件箱的邮件服务器地址（IP形式或字符串形式均可）
        private string mSenderPassword;    //发件箱的密码
        private string mSenderUsername;   //发件箱的用户名（即@符号前面的字符串，例如：hello@163.com，用户名为：hello）
        private bool mEnableSsl;    //是否对邮件内容进行socket层加密传输
        private bool mEnablePwdAuthentication;  //是否对发件人邮箱进行密码验证
