PC DB: More MBG Files Than Local Postoffice Users

• Microsoft Mail for PC Networks, versions 2.1e, 3.0, and 3.2

An MBG file is used to store all incoming or outgoing mail.

There are two types of incoming mailbag files. All local postoffice users will have a unique mailbag that are of the form 0nnnnnnn.MBG. Mail destined for the postoffice that arrives from outside the postoffice is stored temporarily in a file called INQUEUE3.MBG.

Mail that arrives in the INQUEUE3.MBG file will either be distributed to a local user mailbag or forwarded to another outgoing mailbag via the Mailer process.

Outgoing mailbags are one of the following type: external postoffice, FFAPI postoffice, or gateway. The contents of these mailbags can be manipulated by using the Admin program's Queue function.

The version 3.0 Mail postoffice contains a special mailbag, the SYSTEM.MBG mailbag. Mail addressed to network/postoffice/$system will be put here. It is currently used for directory synchronization (Dir-Sync) mail; however, in future versions may also be used for other system mail functions
