Let's say i have 3 smtp appenders in same log4net file whose names are:

<appender name = "emailDevelopment".. />
<appender name = "emailBeta".. />
<appender name = "emailProduction".. />

Let's say i have 3 different servers(Dev, Beta, Production). Depending upon the server, i want to fire the log. In case of Development server, it would fire log from "emailDevelopment". I have a system variable in each server named "ApplicationEnvironment" whose value is Development, Beta, Production based on the server names. Now is there anyway i can setup root in log4net so that it fires email depending upon the server name.

<root>
      <priority value="ALL" />         
      <appender-ref ref="email<environment name from whose appender should be used>" />      
</root>
