A service is an abstraction that collects settings information—usually to set up communication protocols, such as ISP settings—and specific folders for a single instance of an MTM. The behaviour can be different in different MTMs. For example, for SMTP a service typically relates to a single mail account.
If a service can contain entries, opening the service from within a message client application should display these entries.
Users can normally edit service settings using a dialog. It is up to the MTM to provide a dialog for entering and editing settings, and to store them in a suitable stream. In order that settings can be easily accessed both by server-side and client-side MTM components, the code to store and access settings is normally implemented in a separate library.
If the user no longer wants to send or retrieve messages using the service, the user can delete a service entry, which deletes the settings associated with it are removed.
