Sending and receiving e-mail is a very useful function for some applications that perform special tasks. For example, a tool software that monitors the use of a network server resource, if it has the ability to automatically send e-mail, can send an alarm email to the system administrator when it finds that the server's resources are already near the pre set critical state, so that the system administrator can be sent to the system administrator. Take timely measures to avoid major accidents. In Visual Basic, the application can implement the function of sending and receiving e-mail by calling the Microsoft Corp's MAPI (Messaging Application Programming Interface, the message application programming interface).
