No, only http is supported.

You may use the same nginx instance to work with http for this.  This 
also allows load-balancing and so on.

E.g. if you want to use php with fastcgi for this, try something 
like:

mail {
    auth_http  http://localhost:8080/auth.php
    ...
}

http {
     server {
         listen 8080;
         fastcgi_pass ...;
         ...
     }
}

And then run appropriate php fastcgi application as you usually do 
for normal php scripts under nginx.

Of course for really simple cases you may implement your auth 
server in embedded perl or even with rewrite module.  :)  But this 
isn't an option in real life since normally you need to do some 
database lookups and therefore need some context where you may use 
blocking calls.
