On NT, the msgstore channel is used to deliver messages to addresses on the local host. Indeed, on NT, the first msgstore channel seen in the PMDF configuration file is the local channel from the PMDF point of view; features such as aliases, etc., which apply to the "local" channel apply to that first msgstore channel on NT. (This is in contrast to the situation on OpenVMS and UNIX platforms, on which there is a separate l channel---the local channel--- which is distinct from the msgstore channel.) Such delivered messages are stored in the PMDF MessageStore, a message store geared towards IMAP usage, or the PMDF popstore, a message store streamlined for use with POP3 clients, respectively.

Normally, the PMDF MessageStore is used as the main "local" message store on NT platforms, and on NT, the PMDF configuration utility always generates a msgstore channel. The msgstore channel can also deliver to the PMDF popstore, however, so NT sites can, if they prefer, use the PMDF popstore as the main "local" message store; or sites can use both the PMDF popstore and the PMDF MessageStore.

The PMDF MessageStore is a complete message store, with its own management utilities, API, etc. For full details on the PMDF MessageStore and in particular the msgstore channel, see the PMDF popstore & MessageStore Manager's Guide.
