Terms

For administrators of Microsoft Mail (PC), the following list of familiar terms and how they relate to Microsoft Exchange Server terms should help you understand differences between the two products:

MS Mail for PC Networks term	MS Exchange Server equivalent term	Descriptions
External, MMTA	MTA or MS Mail Connector MTA	The MTA is a integral part of the server and moves mail by talking with MTAs at other servers. The MS Mail Connector MTA can move mail between MS Mail PC postoffices. It also moves mail between MS Mail PC postoffices and the MS Mail Connector postoffice.
Windows Remote client	Windows client	All MS Exchange clients are remote clients. They need to have network connectivity to send and read mail.
Postoffice	Server	Postoffices are a collection of files. The server is an active process.
Directory synchronization	Directory replication	Replication occurs as needed within a site and between sites.
Directory synchronization server	Directory bridgehead servers	Replication is a peer-to-peer process within a site. Changes are sent to all servers, not to a central server. Between sites, directory bridgehead servers package up changes and forward them to other sites.
Downstream postoffices	Address space and Connected Sites property page.	When you add a new gateway to a site, configuration is done for the site, not per server. In other sites, you need to change the address space so mail to the gateway is routed to the site the gateway is installed into. This is related to the connected sites property.
Access component	Not applicable	See "Downstream postoffice" for more details.
Import.exe	Directory import and export	Close match of features
Postoffice address list	Site-server-recipients	Custom recipients do not need to be added to server recipient lists to be included in distribution lists.
Postoffice groups	Distribution lists (DLs)	DLs are created once per organization, not per postoffice. DLs are expanded to include all members. Membership in a DL is not limited to mailboxes and custom recipients - it includes public folders and distribution lists.
Modem scripts	Not applicable	Remote clients connect with RAS, Shiva or other remote access network software. Modem scripts are no longer needed for remote client access.
Shared folders	Public folders	Public folders are visible throughout the site. With site affinity, they can be accessible from other sites.
Group folders	Public folders	Public folders are visible throughout the site. Permissions can be assigned to any recipients.
Custom message	Form	Forms are easier to create and use. They no longer require changes to INI files, and are installed in folders or sites.
MSMAIL.INI	EXCHNG.INI or registry entries
SHARED.INI	Enterprise forms registry	Adding a custom form to the enterprise forms registry makes it available to all Windows clients in the site.
Custom command	EXCHNG.INI or registry entries
Custom menus	EXCHNG.INI or registry entries
FOLDCOMP.EXE	Automatic background task or offline.	The private and public information stores repack the data file to move unused space to the end of the file. Offline compaction reduces the size of the file.
MOVEUSER.EXE	Administrator program	Within a site, updating of distribution lists, and permissions on public folders is automatic. Between sites, or into different recipient containers, see the procedure in Microsoft Exchange Server Maintenance and Troubleshooting.
LMEXT.EXE	Administrator program	The file is created in the directory import format.
NOVEXT.EXE	Administrator program	The file is created in the directory import format.
TEMPLATE.EXE	Directory Import and Export in the Administrator program	Modifies more than template information - can also change distribution list members, display name and other properties of a recipient.
Gateway	Connector	Connectors are administered with the Administrator program, and run as Windows NT services on the server.
Mail Message File (MMF)	Personal Folders (PST)	Personal folders are only required for offline use or when not using the Microsoft Exchange Server information store.
