[Dovecot] Dovecot Configuration

Can somebody, please, point me in the right direction in finding a COMPLETE and EXACT definition of the Dovecot configuration hierarchy. In other words what configuration options exist both at the top level but also at each subconfiguration elements (ex. sections etc).

While my C is a bit rusty, I can still make sense of source code and with a bit of effort I will figure it out. I have been going through the src/config/all-settings.c but still have large gaps. A hint in the right direction on how the config works might help clarify and speed things up.

Thanks Andreas Kasenides
