Overview of networking on the MSS

The MSS uses Internet standard networking protocols for message transport and subscriber directory updates. The MSS supports the SMTP/MIME protocol for message transport and supports the LDAP (Lightweight Directory Access Protocol) protocol to communicate with other networked Modular Messaging and Messaging Networking systems and trusted servers such as Avaya Mailbox Manager.

Message transport using SMTP/MIME

The SMTP/MIME protocol has the following message-transport features:

• The ability to create and send multimedia messages to any Internet/Intranet mailbox having an address of the form user@domain.
• The ability to receive any message sent from an Internet/Intranet originator. Originators designate MSS destination mailboxes using addresses of the [email protected].
• The ability to transport messages to and from Internet/Intranet domains. Multimedia message components, such as voice, fax text, and binary media types are transported in MIME format.

Support of the SMTP/MIME protocol has the following benefits:

• Uses standard, non-proprietary protocols.
• Leverages the flexibility of MIME regarding message content.
• Allows messages to be transported natively, without transcoding.
• Allows subscribers to send messages via the Internet to email users.
• Increases subscriber choices for message access to include industry-standard email platforms.
• Provides cost saving to customers by allowing message transport using shared existing Internet facilities.

See Defining MSS System Administration parameters for information on administration of TCP/IP ports, including SMTP.

Subscriber directory updates using LDAP

The LDAP protocol provides an open interface to add, change, delete, and query directories between two systems. LDAP on the MSS supports the following subscriber directory functionality:

• Accepts requests for changes in the local subscriber directory, including additions, changes, and deletions.
• Initiates requests for a remote subscriber update from an administered networked machine.
• Accepts requests from administered networked machines for an update of local subscribers.
• Authenticates both incoming and outgoing update sessions.
