基于RHQ配置邮件预警（Email Alert）
写在前面
关于Rhq的安装，请参考《RHQ简介与安装》,之前安装演示中对应的版本为rhq3.0，现在配置邮件预警使用的版本为RHQ4.2，不过安装过程大同小异，还是具有参考价值的。
实现原理
Rhq发送预警邮件的实现原理是通过调用其内置jboss服务器的mail服务来完成的。Rhq安装过程中会要求用户填写smtp服务器地址、smtp服务器端口以及账户信息。但是对于某些需要授权信息的邮件服务器来说，这还是不够的，还需要修改其内置服务器中关于mail服务的相关配置。
mail服务的配置文件是%RHQ_Hom%e\jbossas\server\default\deploy下的mail-service.xml文件
