I recently switched my main webserver (where I host clients' websites) from apache to nginx and I wrote a custom generic configuration file to handle everything in one place, so domains and subdomains are handled on the fly by creating directories and subdirectories.

Use server_name. Instead of

if ($host ~* ^(.*)\.(.*\..*)$) {
set $sub $1;
set $domain $2;
}

you may write in 0.7.x

server {
listen 80 default;
server_name ~^(.*)\.(.*\..*)$;
set $sub $1;
set $domain $2;

...
}

As to the redirect:

server {
listen 80 default;
server_name _;
rewrite ^ http://www.$host$request_uri?;
}

server {
listen 80 default;
server_name www.*;
...
}
