\preliminary
\brief The QMailServiceConfiguration class provides a simple framework for creating
wrappers classes that simplify service configuration management.
QMailServiceConfiguration provides a simple interface for manipulating the configuration
parameters of a single service within an account configuration. For each specific
service implemented, a configuration class derived from QMailServiceConfiguration
should be implemented to make the configuration easily accessible.

\enum QMailServiceConfiguration::ServiceType
This enum type is used to describe the type of a service
\value Unknown The type of the service is unknown.
\value Source The service is a message source.
\value Sink The service is a message sink.
\value SourceAndSink The service is both a message source and a message sink.
\value Storage The service is a content manager.
