Hi, I’m brand new to nginx and I am trying to convert the app I wrote  
over from Apache as I need the ability to serve a lot of clients at once  
without a lot of overhead! I’m getting the hang of setting up nginx and  
FastCGI PHP but I can’t wrap my head around nginx’s rewrite format just  
yet. I know you have to write some simple script that goes in the server  
{} block in the nginx config but I’m not yet familiar with the syntax.  
Could anyone with experience with both Apache and nginx help me convert  
this to nginx format? Thanks!

No, you should not use this sendmail style configuration.  
However, I do not understand what the original htaccess should do.
