Projeto de um protocolo para a recuperação eficiente de informação em caixas postais eletrônicas.

Abstract

This work presents a proposal for a new protocol for the access and retrieval of messages in an Internet eletronic mail system. Currently there are two protocols that can be used to access and retrieve messages. This kind of work is made by the POP and IMAP protocols. None of these protocols offer functionality that helps in the automatic administration of electronic mailboxes. A new protocol, named Smart Post Office Protocol - SPOP, stores the messages in the mail server, associated with special messages folders, called Smart Folders or SFolders. Each SFolder has a rule that specifies the kind of messages that it will store. This work also defines a language that is used to contruct the rules of a SFolder, called Smart Folder Definition Language (SFDL). Once the SFolder has been created, the entire message classification process is performed automatically, ensuring the consistency of the classification whenever the client accesses the mailbox. The retrieval of messages can then be performed efficiently.
