The goal of this java programming assignment is to create a simple mail client

that sends e$-$mail to any recipient. Your client will need to establish a TCP

connection with a mail server $($e$.$g$.,$ a Google mail server$),$ dialogue with the

mail server using the SMTP protocol, send an e$-$mail message to a recipient

$($e$.$g$.,$ your friend$)$ via the mail server, and finally close the TCP connection with

the mail server.

For this assignment, the Companion Website provides the skeleton code for

your client. Your job is to complete the code and test your client by sending e$-$

mail to different user accounts. You may also try sending through different

servers $($for example, through a Google mail server and through your university

mail server$).$
