I am working on a ruby app where the user fills out a form that gets  
sent via email. Sometimes I work on the app at my computer at home and  
other times at work. I need to setup the development environment so  
that the app detects which server it is currently running on and uses  
the appropriate smtp host. I am relatively new to Ruby on Rails, so am  
not sure of the best way to do this. Thanks for any help.

I would probably keep it simple and just check the hostname of the  
machine by making a system call in development.rb

`hostname` # =\> ‘dev\_box1’

Hope this helps.

Or you could have 2 environements, development\_home, and development  
office, with the majority of settings being common, but with different  
smtp stuff.
