Not sure if it's of interest, but you might want to look at the postfix 
mailserver configuration setup and see if that translates to an API.

postconf  lists the configuration settings (in alphabetical order)
postconf -n  list non-default settings
postconf <setting>  display "setting = value"
postconf -e <setting> = <value>  edit the configuration file, changing that setting

The editing option replaces any existing version of that setting and 
adds the new value at the end of the file.

Having all the values at the end of the file works well, because for a 
simple setup you don't need to change many settings and they don't 
depend on order.
