Help converting Apache HTACCESS directives to nginx?

Server NGINX
1

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.
