The Remote Mailslot Protocol is a simple, unreliable, insecure, and unidirectional interprocess communications (IPC) protocol between a client and server. A mailslot server creates a mailslot, and a mailslot client writes messages to the mailslot created by the server. The server then reads these messages, thus achieving communication between the client and server. A mailslot is represented locally on the server as a file.
