Then you need to figure out what environment variables are needed, and use  
the import command to import them from the parent environment.

However, that only works if they are present in the parent environment to  
start with. When maildrop gets executed by your mail server, your mail  
server has no knowledge of the desktop environment that you're currently  
running, or even if you're logged in at all, and it won't have your desktop  
environment.

This is, basically, how to execute an external program from maildrop. How to  
actually get it what it needs to run, you'll need to figure that one out.
