use case diagrams

The Use Case Diagram 


In many design processes, the use case diagram is the first that designers will work with when starting a project.  This diagram allows for the specification of high level user goals that the system must carry out.  These goals are not necessarily tasks or actions, but can be more general required functionality of the system.

SMTP

Simple Mail Transfer Protocol, a protocol for sending e-mail messages between servers. Most e-mail systems that send mail over the Internet use SMTP to send messages from one server to another; the messages can then be retrieved with an e-mail client using either POP or IMAP. In addition, SMTP is generally used to send messages from a mail client to a mail server. This is why you need to specify both the POP or IMAP server and the SMTP server when you configure your e-mail application.
