Message Posting Protocol
The Message Posting Protocol (MPP) operates on port 218 and facilitates the transfer and management of message posts across networked systems. It provides a mechanism for clients and servers to communicate by supporting both TCP and UDP transport. Widely referenced in official port documentation, it serves specific messaging-centric applications in distributed environments..
Message Posting Protocol (MPP) is designed to enable systems to post, transfer, and update messages across network nodes. MPP supports both connection-oriented (TCP) and connectionless (UDP) transports, providing flexibility depending on the requirements of reliability or speed.
MPP facilitates various functions such as message creation, retrieval, deletion, and management. It may operate similarly to basic networked messaging services by structuring message envelopes, addressing, and sequencing to ensure orderly communication between multiple clients and servers.
Although not widely utilized in mainstream modern messaging, MPP's standardized port assignment persists for compatibility with legacy systems and specialized applications. Its simplicity allows integration within lightweight or custom communication frameworks where structured message exchange is necessary.
